Methods A total of 100 BD patients and 129 healthy controls (HCs) were included in the study conducted at Ankara Etlik City Hospital Psychiatry Clinic. These patients were diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), and the Structured Clinical Interview for DSM-5 (SCID-5). Sociodemographic forms, the Turkish Vesion of BEDS, the Young Mani Rating Scale (YMRS), the Hamilton Depression Rating Scale (HAM-D), the Brief Psychiatric Rating Scale (BPRS), the Bulumic Investigatory Test Edinburgh (BITE), and the Dutch Eating Behavior Questionnaire (DEBQ) were used to assess validity and reliability. Results No statistically significant differences were found between the patient and control groups regarding the total and subscale scores of the BITE, BEDS, and DEBQ. The correlation coefficient between each item and the total score ranged from 0.313–0.644. Cronbach's alpha for the scale was 0.821. The removal of any items from the original scale did not lead to an improvement in Cronbach’s alpha. The BEDS score was found to be significantly correlated with the BITE score, DEBQ total score, emotional eating score, and external eating score (p < 0.001). There was no correlation between the BEDS score and the DEBQ Restrictive Eating Rubscale, YMRS, BPRS, or HAM-D scale scores. Conclusion The Turkish version of the BEDS is a valid and reliable scale that can be used as an assessment tool in the evaluation of eating disorders in the Turkish BD population. Validity Reliability Bipolar Disorder Barcelona Bipolar Eating Disorder Scale Eating Disorder INTRODUCTION Bipolar disorder (BD) is a chronic psychiatric illness affecting approximately 1% of the population and is characterized by recurring mood episodes, typically alternating between depression and mania and/or hypomania ( 1 , 2 ). Research indicates that nearly 70% of individuals develop symptoms before the age of 25 ( 3 ). BD is frequently accompanied by psychiatric comorbidities, which substantially impair social, occupational, and family functioning ( 4 ). Comorbidity is particularly common in BD type 1 patients ( 5 ) and has been associated with poorer outcomes, earlier onset, and a reduced treatment response ( 6 ). Moreover, mixed mood features and a higher frequency of suicidal behaviors are more prevalent in BD patients with comorbid conditions ( 7 , 8 ). The most commonly observed comorbidities include anxiety disorders, substance use disorders (SUD), obsessive–compulsive disorder (OCD), attention-deficit/hyperactivity disorder (ADHD), various personality disorders, and eating disorders (ED) ( 9 – 11 ). BD and ED display multiple overlapping clinical characteristics that point to a clinically meaningful association between the two conditions ( 12 ). A central feature common to both is impulsivity. In BD, impulsive behaviors can manifest across different mood states, ranging from excessive spending and risky sexual behaviors during manic episodes to substance misuse or self-harming tendencies during depressive phases ( 13 ). Comparable patterns are evident in binge eating disorder (BED), where recurrent, uncontrolled eating episodes are driven by diminished inhibitory control and a sense of loss of restraint ( 14 ). This shared tendency toward impulsive action is one reason why both BD and ED frequently cooccur with other psychiatric disorders characterized by deficits in self-regulation, such as SUD, ADHD, borderline personality disorder, and impulse-control disorders ( 15 ). Another domain of convergence is mood and affective instability. BD is defined by cyclical fluctuations between manic, depressive, or mixed states ( 16 ), whereas ED patients often exhibit heightened reactivity to emotional stress, rapid mood shifts, and difficulties in regulating negative affect, particularly in the context of eating and body image ( 17 ). These parallels suggest that affective dysregulation may serve as a transdiagnostic vulnerability factor that contributes to the onset and persistence of both disorders. Notably, BD and ED tend to emerge in adolescence or early adulthood, a sensitive developmental window in which they can substantially impair academic achievement, social relationships, and occupational functioning ( 18 ). Epidemiological studies provide further support for this overlap. The reported prevalence rates of ED in individuals with BD range between 6% and 31%, which are significantly higher than those reported in the general population ( 12 ). Meta-analytic evidence suggests that individuals with bipolar disorder have a substantially increased risk of developing ED, with BED and bulimia nervosa emerging as the most prevalent comorbid conditions ( 15 ). Importantly, the coexistence of BD and ED has been associated with a more severe illness trajectory, including earlier onset of BD, increased frequency of mood episodes, greater risk of suicidality, greater likelihood of mixed affective states, and reduced psychosocial functioning ( 16 , 17 ). The Barcelona Bipolar Eating Disorder Scale (BEDS) is a concise, self-report instrument developed by Carla Torrent, Eduard Vieta, and colleagues in 2004 to screen for disordered eating behaviors in individuals with BD ( 19 ). This tool consists of ten items and was designed as a rapid and clinically practical tool to capture eating pathology that may be overlooked by standard eating disorder measures, particularly given the influence of mood instability and impulsivity on eating patterns in BD patients. Subsequent multicenter validation confirmed its reliability, validity, and sensitivity to change, with prevalence estimates highlighting its clinical utility ( 20 ). In addition to its original Spanish version, the scale has also been validated in French populations, further supporting its cross-cultural applicability ( 21 ). Despite these advances, a validated Turkish version of the BEDS is lacking. Considering that eating behaviors are culturally embedded, linguistic adaptation and validation are crucial to ensure psychometric accuracy ( 22 ). Furthermore, comorbidity with BD and an eating disorder is associated with earlier onset, increased frequency of episodes, greater suicidality, and poorer functional outcomes ( 15 ). Therefore, systematic screening in Turkish clinical populations is particularly important. Turkish versions of many eating disorder measurement tools are available. However, there is no Turkish version that can be used to diagnose and screen for ED in the BD population. A culturally adapted version would not only enhance diagnostic accuracy and early intervention but also enable international comparability in research ( 23 ). In conclusion, the overlapping features of BD and ED, such as impulsivity, emotional dysregulation, early onset, and increased comorbidity, highlight the importance of an integrated clinical approach ( 24 ). Therefore, systematic assessment of eating-related pathology in BD patients, followed by timely and personalized interventions, is essential to improve patient prognosis and reduce the cumulative burden of these comorbid disorders. Given these associations, the development of simple, self-administered tools to screen for ED symptoms in BD patients is crucial to prevent missed or delayed diagnoses. This study aims to adapt the BEDS to the Turkish population and assess its validity and reliability in both clinical and nonclinical populations. METHOD Participants and Procedure The study included consecutive patients with BD who presented to the Psychiatry Clinic of Etlik City Hospital between January 2024 and February 2025. Diagnostic evaluations were conducted in accordance with the DSM-5 criteria and verified through the Structured Clinical Interview for DSM-5 (SCID-5). The participants’ current clinical status was evaluated via the Young Mania Rating Scale (YMRS) and the Hamilton Depression Rating Scale (HAM-D) to ascertain whether they were in a remitted or acute episode. The control group was composed of psychiatrycally healthy volunteers recruited from the Family Medicine Clinic of the same hospital. To exclude patients with psychiatric conditions, both the SCID-I and SCID-II were administered. The eligibility criteria for both groups included being between 18 and 65 years of age, having literacy in Turkish, having sufficient cognitive ability to complete questionnaires and interviews, and being willing to participate. The exclusion criteria included the presence of intellectual disability, psychotic disorders, alcohol or SUD, OCD, ADHD, personality disorders, severe medical conditions, or any other psychiatric diagnosis confirmed through the SCID-5. All required permissions to use the relevant scales were secured from their original developers to conduct the validity and reliability assessment of the Turkish version of the BEDS. Ethics Committee Approval: Before starting this study, permission was obtained from the ethics committee of the Scientific Research Committee of Ankara Dışkapı Yıldırım Beyazıt Training and Research Hospital (date: 07/01/2019, number: 58/14). All stages of the study were carried out in according to provisions of the Declaration of Helsinki as revised in Edinburgh 2000. Each participant was informed about the study beforehand and informed consent was obtained from all of them. Clinical trial number: not applicable Translation and Adaptation of the Scale The BEDS was translated into Turkish via a forward–backward translation procedure. Initially, a bilingual psychiatrist who was a native Spanish speaker translated the scale into Turkish. A second psychiatrist, blinded to the original version, performed a back-translation into Spanish. Discrepancies were resolved through consensus, and the final Turkish version was approved after pilot testing in a small patient sample to ensure linguistic clarity and cultural appropriateness. No further modifications were needed. All participants received comprehensive information regarding the study’s objectives and procedures, and written informed consent was obtained prior to the interviews and scale administration. During the baseline assessment, all participants were administered the YMRS and HAM-D. The cut-off score for both the YMRS and HAM-D was set at 7 (25, 26), and four patients were excluded from the study due to a YMRS score above 7 and two patients due to a HAM-D score above 7. Those with euthymia were first administered the SCID, and then the following assessments were administered to patients and healthcare professionals: the sociodemographic data collection form (BEDS), the Edinburgh Bulimia Research Scale (EBAT), the Dutch Eating Behavior Questionnaire (DEBQ), and the brief psychiatric rating scale (BPRS). Seven patients who completed the scales incompletely or incorrectly were excluded from further assessment. Twelve participants were excluded due to comorbid psychiatric disorders. Five of them had the comorbid OCD diagnosis and seven had the comorbid panic disorder diagnosis, Ultimately, 100 BD patients and 129 healthy controls were included in the study. Data collection tools Sociodemographic Data Collection Form : A structured sociodemographic and clinical information form was designed specifically by the research team for this study. This form included items assessing demographic variables such as age, sex, marital status, educational attainment, employment status, and income level as well as clinical variables such as age at illness onset, illness duration, family history of psychiatric and medical disorders, previous hospitalizations, history of depressive and manic episodes, and current medication use. Information regarding physical comorbidities and metabolic syndrome components was also documented. Young Mania Rating Scale (YMRS) : The YMRS, originally developed by Young and colleagues, is one of the most commonly used clinician-administered instruments for assessing manic symptom severity (27). The scale comprises 11 items evaluating domains such as elevated mood, motor activity or energy, sexual interest, sleep, irritability, speech, thought content, disruptive or aggressive behavior, appearance, and insight. Seven items are rated on a five-point Likert scale, whereas the remaining four are rated on a nine-point scale. The total scores range from 0 to 44, with higher scores reflecting greater manic symptom severity. The Turkish adaptation was validated by Karadağ et al. (28), who demonstrated its reliability and validity in clinical populations. Hamilton Depression Rating Scale (HAM-D) : The HAM-D, originally developed by Hamilton, is a clinician-rated scale designed to assess the severity of depressive symptomatology. In this study, the 17-item version was employed, covering domains such as mood, guilt, suicidal ideation, sleep disturbances, agitation, anxiety, weight loss, and somatic complaints. The items are rated on either a three- or five-point scale, with higher scores reflecting greater severity of depressive symptoms. In clinical practice, scores between 16–25 reflect mild depression, scores between 26–40 indicate moderate depression, and scores above 40 indicate severe depression. The Turkish version has been validated and shown to be reliable by Akdemir et al. (29). Edinburgh Bulimia Research Test (EBAT) : The EBAT, also known as the Bulimic Investigatory Test, Edinburgh (BITE), was developed by Henderson and Freeman in 1987 (30) as a self-report questionnaire for assessing bulimia-related symptoms and eating attitudes. It consists of 33 items (36 questions in total due to subitems), the majority of which are scored dichotomously (“Yes/No”). Five items are reverse-scored to reduce response bias. In addition, six items evaluate symptom frequency and severity via graded response options. Total scores ≥20 indicate the presence of binge eating, scores between 10–19 suggest abnormal eating attitudes, and scores <10 are considered nonpathological. The reported Cronbach’s alpha values are 0.87 for the symptom scale and 0.62 for the severity subscale. The Turkish validation study confirmed its psychometric adequacy in a sample of university students (31). Barcelona Bipolar Eating Disorder Scale (BEDS) : The BEDS was specifically developed to provide a brief, self-administered screening tool for the detection of eating disturbances in patients with BD (20). It comprises 10 items scored on a four-point scale (0–3), with higher values reflecting greater severity of eating pathology. The item scores are summed to yield a total score, which represents the overall severity of ED symptoms. The scale was originally validated in Spanish populations by Torrent et al. (20) and subsequently adapted into French (21). The Turkish adaptation in the present study followed a rigorous translation–back-translation process to ensure semantic and conceptual equivalence. Dutch Eating Behavior Questionnaire (DEBQ) : The DEBQ, developed by Van Strien et al. (32), is a 33-item self-report instrument assessing three dimensions of eating behavior: emotional eating (13 items), external eating (10 items), and restrained eating (10 items). Each item is rated on a five-point Likert scale ranging from “never” (1) to “very often” (5). Factor analyses of both the original and Turkish versions confirmed the three-factor structure. The reliability coefficients are high, with Cronbach’s alpha values reported as 0.95 for restrained eating, 0.94 for emotional eating, and 0.80 for external eating in Dutch samples. The Turkish version demonstrated comparable psychometric properties, with alphas of 0.91, 0.92, and 0.72 for restrained, emotional, and external eating, respectively (33). Brief Psychiatric Rating Scale (BPRS) : Originally developed by Overall and Gorham in 1962 (34), the BPRS is a clinician-administered scale designed to evaluate psychiatric symptom severity across a wide range of domains. The version employed in this study includes 18 items assessing symptoms such as anxiety, depression, hostility, suspiciousness, hallucinations, unusual thought content, conceptual disorganization, and emotional withdrawal. Each item is scored on a 7-point scale (0 = not present to 6 = extremely severe), yielding a total score ranging from 0--108. Scores between 15–30 generally indicate mild symptomatology, whereas scores ≥30 suggest severe psychopathology. The Turkish validation study was conducted by Soykan in 1990 (35), confirming the instrument’s clinical utility. Statistical analysis Internal consistency was evaluated via Cronbach’s alpha, and item–total correlations as well as Cronbach’s alpha values if an item was deleted were calculated. Construct validity was assessed through principal component analysis, which was supported by the Kaiser–Meyer–Olkin (KMO) measure and Bartlett’s test of sphericity. Convergent validity was examined by calculating Pearson correlation coefficients between the BEDS and other measures (DEBQ, BITE, YMRS, HAM-D, and BPRS). Group differences were analyzed via independent-samples t tests and chi-square tests, with statistical significance set at p < 0.05. RESULTS The comparisons of employment status, educational status, smoking status, marital status, weight status, income level, BITE and BEDS scores, total and subscale DEBQ scores and years of education between the BD and HC groups and the YMRS, HAM-D and BPRS scores of the BD group are shown in Table 1 . A statistically significant difference was detected between the BD and HC groups in terms of age, employment, smoking status, education, weight status and income level (p < 0.001) (Table 1 ).

A principal component analysis was conducted on all 10 items of the BEDS. The KMO value of 0.846 indicated sampling adequacy, supporting the use of factor analysis in the entire sample. Bartlett’s test of sphericity was statistically significant (χ² = 640.005, df = 45, p < 0.001), confirming the suitability of the data for factor analysis. Table 3 presents the factor loadings, which ranged from 0.341–0.717. The eigenvalue for the identified factor (severity and frequency of worry) was 3.326, accounting for 33.256% of the total variance.

The correlations between the BEDS total score and these measures for the entire sample are presented in Table 4 . Correlation analyses revealed a negative association with BITE (p < 0.001). In contrast, the BEDS total score was positively correlated with the DEBQ total score as well as with the scores of the emotional and external eating subscales (all p < 0.001). No significant associations were observed with the DEBQ restrictive eating subscale, YMRS, BPRS, or HAM-D.

DISCUSSION This study aimed to adapt the BEDS into Turkish and examine its psychometric properties in a clinical sample of individuals with bipolar disorder and healthy controls. The results strongly support the use of the Turkish version of the BEDS as a valid and reliable instrument for identifying disordered eating behaviors in this population. The Barcelona Bipolar Eating Disorder Scale is a brief self-report instrument designed to assess disordered eating behaviors specifically within the context of bipolar disorder. It evaluates impulsive and emotion-driven eating tendencies, such as loss of control over eating, binge-like episodes, and eating in response to mood fluctuations. Rather than diagnosing a specific eating disorder, the BEDS captures the overall severity and frequency of eating-related disturbances that may emerge as part of affective instability and impulsivity in individuals with bipolar disorder. Therefore, establishing a valid and reliable version of such a scale for Turkish-speaking populations would increase its utility in both academic research and clinical practice, ultimately facilitating clinicians’ ability to monitor and follow patients more effectively. The internal consistency of the Turkish BEDS was found to be high (Cronbach's alpha = 0.821), which is comparable to the values reported in the original Spanish validation (0.79) ( 20 ) and the French version (0.82) ( 21 ). These results suggest that the scale maintains its reliability across different languages and cultural contexts. The item–total correlations ranged between 0.31 and 0.64, confirming that all the items contributed meaningfully to the underlying construct. These findings suggest that the BEDS reliably captures a coherent dimension of eating pathology, as it manifests in BD. Exploratory factor analysis supported a unidimensional structure, with factor loadings ranging from 0.34–0.72 and a single factor explaining 33.26% of the total variance. The Kaiser–Meyer–Olkin measure (0.85) and the significant Bartlett’s test (χ² = 640.01, p < 0.001) verified the adequacy of the data for factor analysis. This structure corresponds closely to the original validation, suggesting that the Turkish version preserves both the semantic and conceptual integrity of the scale. One of the problems with the scales used to assess psychiatric disorders is their length and/or the need for expert administration, which limits their clinical utility ( 20 ). In brief, self-administered screening measures are particularly valuable in clinical practice, where lengthy or interviewer-based instruments can be difficult to administer. Given the high comorbidity rates of BD and ED—especially binge eating disorder and bulimia nervosa—early detection of eating pathology in this population is essential ( 18 ). In line with this, the significant correlations observed between BEDS total scores and the emotional and external eating subscales of the DEBQ underscore the instrument's clinical sensitivity. The lack of correlation with restrained eating suggests that the BEDS focuses primarily on loss of control and emotion-focused eating rather than cognitively controlled dietary restriction. The inverse correlation with the Edinburgh Bulimic Investigation Test (BITE) may be attributed to differences in scoring direction and item framing between the two scales. Considering this context, the results are consistent with previous evidence linking BD to binge-eating symptomatology ( 24 ). Furthermore, the lack of correlation between BEDS scores and the YMRS, HAM-D, or BPRS supports the scale's discriminant validity and suggests that eating disorders are not merely reflections of existing manic, depressive, or general psychopathological states. This finding suggests that such tendencies may represent enduring personality traits rather than transient mood-related phenomena in BD patients. From a clinical perspective, the BEDS offers several practical advantages. Its brevity, clarity, and self-reported design make it suitable for use in time-constrained psychiatric settings ( 21 ). Unlike more extensive instruments such as the DEBQ or BITE, the BEDS specifically targets impulsive and emotionally reactive eating behaviors, which are common yet often overlooked in BD ( 17 ). Early identification of these symptoms is crucial, given the established links between BD–ED comorbidity and poorer clinical outcomes, including earlier onset, increased episode frequency, elevated suicidality, and reduced psychosocial functioning ( 24 ). The Turkish adaptation provides clinicians with a culturally appropriate and psychometrically sound tool for identifying such comorbidities. Routine application may enhance early intervention and contribute to a more integrative understanding of BD by accounting for both affective and behavioral dysregulation. Cultural and linguistic adaptation is vital when psychological instruments are translated, as eating behaviors are strongly influenced by cultural norms regarding food, body image, and emotional expression. The successful validation of the Turkish BEDS demonstrated that the construct of impulsivity-driven, emotionally mediated eating is recognizable and clinically relevant in the Turkish population. This achievement not only improves diagnostic precision in local practice but also promotes cross-cultural comparability in international BD and ED research. This study has several strengths. Compared with previous validation efforts, the present study included a relatively larger sample size (100 BD patients and 129 healthy controls). Moreover, the diagnostic accuracy of the clinical sample was ensured through the use of structured interviews (SCID-5), thereby increasing methodological rigor. Nevertheless, several limitations must be acknowledged. First, the patient sample consisted solely of individuals with BD type I, limiting generalizability to other BD subtypes, such as type II or cyclothymia. Second, the cross-sectional design prevents assessment of the scale’s sensitivity to longitudinal changes or treatment outcomes. Third, although the sample size was adequate for psychometric testing, future studies should include larger and more diverse samples to examine measurement invariance across gender, age, and illness stage. Third, although the sample size was adequate for psychometric testing, future studies should include larger and more diverse samples to examine measurement invariance across gender, age, and illness stage. In summary, the Turkish version of the Barcelona Bipolar Eating Disorder Scale has excellent psychometric properties, including high internal consistency, a coherent factor structure, and meaningful convergent validity. The scale effectively identifies impulsive and emotion-driven eating behaviors that are prevalent yet often underrecognized among individuals with bipolar disorder. Its brevity and ease of administration make it well suited for both clinical practice and research. Integrating the BEDS into routine assessment protocols may facilitate early detection of comorbid eating disturbances and enhance comprehensive care and prognosis in patients with bipolar disorder.

Reliability","fulltext":[{"header":"INTRODUCTION","content":"\u003cp\u003eBipolar disorder (BD) is a chronic psychiatric illness affecting approximately 1% of the population and is characterized by recurring mood episodes, typically alternating between depression and mania and/or hypomania (\u003cspan citationid=\"CR1\" class=\"CitationRef\"\u003e1\u003c/span\u003e, \u003cspan citationid=\"CR2\" class=\"CitationRef\"\u003e2\u003c/span\u003e). Research indicates that nearly 70% of individuals develop symptoms before the age of 25 (\u003cspan citationid=\"CR3\" class=\"CitationRef\"\u003e3\u003c/span\u003e). BD is frequently accompanied by psychiatric comorbidities, which substantially impair social, occupational, and family functioning (\u003cspan citationid=\"CR4\" class=\"CitationRef\"\u003e4\u003c/span\u003e). Comorbidity is particularly common in BD type 1 patients (\u003cspan citationid=\"CR5\" class=\"CitationRef\"\u003e5\u003c/span\u003e) and has been associated with poorer outcomes, earlier onset, and a reduced treatment response (\u003cspan citationid=\"CR6\" class=\"CitationRef\"\u003e6\u003c/span\u003e). Moreover, mixed mood features and a higher frequency of suicidal behaviors are more prevalent in BD patients with comorbid conditions (\u003cspan citationid=\"CR7\" class=\"CitationRef\"\u003e7\u003c/span\u003e, \u003cspan citationid=\"CR8\" class=\"CitationRef\"\u003e8\u003c/span\u003e). The most commonly observed comorbidities include anxiety disorders, substance use disorders (SUD), obsessive\u0026ndash;compulsive disorder (OCD), attention-deficit/hyperactivity disorder (ADHD), various personality disorders, and eating disorders (ED) (\u003cspan additionalcitationids=\"CR10\" citationid=\"CR9\" class=\"CitationRef\"\u003e9\u003c/span\u003e\u0026ndash;\u003cspan citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e).\u003c/p\u003e\u003cp\u003eBD and ED display multiple overlapping clinical characteristics that point to a clinically meaningful association between the two conditions (\u003cspan citationid=\"CR12\" class=\"CitationRef\"\u003e12\u003c/span\u003e). A central feature common to both is impulsivity. In BD, impulsive behaviors can manifest across different mood states, ranging from excessive spending and risky sexual behaviors during manic episodes to substance misuse or self-harming tendencies during depressive phases (\u003cspan citationid=\"CR13\" class=\"CitationRef\"\u003e13\u003c/span\u003e). Comparable patterns are evident in binge eating disorder (BED), where recurrent, uncontrolled eating episodes are driven by diminished inhibitory control and a sense of loss of restraint (\u003cspan citationid=\"CR14\" class=\"CitationRef\"\u003e14\u003c/span\u003e). This shared tendency toward impulsive action is one reason why both BD and ED frequently cooccur with other psychiatric disorders characterized by deficits in self-regulation, such as SUD, ADHD, borderline personality disorder, and impulse-control disorders (\u003cspan citationid=\"CR15\" class=\"CitationRef\"\u003e15\u003c/span\u003e).\u003c/p\u003e\u003cp\u003eAnother domain of convergence is mood and affective instability. BD is defined by cyclical fluctuations between manic, depressive, or mixed states (\u003cspan citationid=\"CR16\" class=\"CitationRef\"\u003e16\u003c/span\u003e), whereas ED patients often exhibit heightened reactivity to emotional stress, rapid mood shifts, and difficulties in regulating negative affect, particularly in the context of eating and body image (\u003cspan citationid=\"CR17\" class=\"CitationRef\"\u003e17\u003c/span\u003e). These parallels suggest that affective dysregulation may serve as a transdiagnostic vulnerability factor that contributes to the onset and persistence of both disorders. Notably, BD and ED tend to emerge in adolescence or early adulthood, a sensitive developmental window in which they can substantially impair academic achievement, social relationships, and occupational functioning (\u003cspan citationid=\"CR18\" class=\"CitationRef\"\u003e18\u003c/span\u003e).\u003c/p\u003e\u003cp\u003eEpidemiological studies provide further support for this overlap. The reported prevalence rates of ED in individuals with BD range between 6% and 31%, which are significantly higher than those reported in the general population (\u003cspan citationid=\"CR12\" class=\"CitationRef\"\u003e12\u003c/span\u003e). Meta-analytic evidence suggests that individuals with bipolar disorder have a substantially increased risk of developing ED, with BED and bulimia nervosa emerging as the most prevalent comorbid conditions (\u003cspan citationid=\"CR15\" class=\"CitationRef\"\u003e15\u003c/span\u003e). Importantly, the coexistence of BD and ED has been associated with a more severe illness trajectory, including earlier onset of BD, increased frequency of mood episodes, greater risk of suicidality, greater likelihood of mixed affective states, and reduced psychosocial functioning (\u003cspan citationid=\"CR16\" class=\"CitationRef\"\u003e16\u003c/span\u003e, \u003cspan citationid=\"CR17\" class=\"CitationRef\"\u003e17\u003c/span\u003e).\u003c/p\u003e\u003cp\u003eThe Barcelona Bipolar Eating Disorder Scale (BEDS) is a concise, self-report instrument developed by Carla Torrent, Eduard Vieta, and colleagues in 2004 to screen for disordered eating behaviors in individuals with BD (\u003cspan citationid=\"CR19\" class=\"CitationRef\"\u003e19\u003c/span\u003e). This tool consists of ten items and was designed as a rapid and clinically practical tool to capture eating pathology that may be overlooked by standard eating disorder measures, particularly given the influence of mood instability and impulsivity on eating patterns in BD patients. Subsequent multicenter validation confirmed its reliability, validity, and sensitivity to change, with prevalence estimates highlighting its clinical utility (\u003cspan citationid=\"CR20\" class=\"CitationRef\"\u003e20\u003c/span\u003e). In addition to its original Spanish version, the scale has also been validated in French populations, further supporting its cross-cultural applicability (\u003cspan citationid=\"CR21\" class=\"CitationRef\"\u003e21\u003c/span\u003e).\u003c/p\u003e\u003cp\u003eDespite these advances, a validated Turkish version of the BEDS is lacking. Considering that eating behaviors are culturally embedded, linguistic adaptation and validation are crucial to ensure psychometric accuracy (\u003cspan citationid=\"CR22\" class=\"CitationRef\"\u003e22\u003c/span\u003e). Furthermore, comorbidity with BD and an eating disorder is associated with earlier onset, increased frequency of episodes, greater suicidality, and poorer functional outcomes (\u003cspan citationid=\"CR15\" class=\"CitationRef\"\u003e15\u003c/span\u003e). Therefore, systematic screening in Turkish clinical populations is particularly important. Turkish versions of many eating disorder measurement tools are available. However, there is no Turkish version that can be used to diagnose and screen for ED in the BD population. A culturally adapted version would not only enhance diagnostic accuracy and early intervention but also enable international comparability in research (\u003cspan citationid=\"CR23\" class=\"CitationRef\"\u003e23\u003c/span\u003e).\u003c/p\u003e\u003cp\u003eIn conclusion, the overlapping features of BD and ED, such as impulsivity, emotional dysregulation, early onset, and increased comorbidity, highlight the importance of an integrated clinical approach (\u003cspan citationid=\"CR24\" class=\"CitationRef\"\u003e24\u003c/span\u003e). Therefore, systematic assessment of eating-related pathology in BD patients, followed by timely and personalized interventions, is essential to improve patient prognosis and reduce the cumulative burden of these comorbid disorders. Given these associations, the development of simple, self-administered tools to screen for ED symptoms in BD patients is crucial to prevent missed or delayed diagnoses. This study aims to adapt the BEDS to the Turkish population and assess its validity and reliability in both clinical and nonclinical populations.\u003c/p\u003e"},{"header":"METHOD","content":"\u003cp\u003e\u003cstrong\u003eParticipants and Procedure\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eThe study included consecutive patients with BD who presented to the Psychiatry Clinic of Etlik City Hospital between January 2024 and February 2025.

Those with euthymia were first administered the SCID, and then the following assessments were administered to patients and healthcare professionals: the sociodemographic data collection form (BEDS), the Edinburgh Bulimia Research Scale (EBAT), the Dutch Eating Behavior Questionnaire (DEBQ), and the brief psychiatric rating scale (BPRS). Seven patients who completed the scales incompletely or incorrectly were excluded from further assessment. Twelve participants were excluded due to comorbid psychiatric disorders. Five of them had the comorbid OCD diagnosis and seven had the comorbid panic disorder diagnosis, Ultimately, 100 BD patients and 129 healthy controls were included in the study.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eData\u0026nbsp;\u003c/strong\u003e\u003cstrong\u003ecollection tools\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eSociodemographic Data Collection Form\u003c/strong\u003e: A structured sociodemographic and clinical information form was designed specifically by the research team for this study. This form included items assessing demographic variables such as age, sex, marital status, educational attainment, employment status, and income level as well as clinical variables such as age at illness onset, illness duration, family history of psychiatric and medical disorders, previous hospitalizations, history of depressive and manic episodes, and current medication use. Information regarding physical comorbidities and metabolic syndrome components was also documented.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eYoung Mania Rating Scale (YMRS)\u003c/strong\u003e: The YMRS, originally developed by Young and colleagues, is one of the most commonly used clinician-administered instruments for assessing manic symptom severity (27). The scale comprises 11 items evaluating domains such as elevated mood, motor activity or energy, sexual interest, sleep, irritability, speech, thought content, disruptive or aggressive behavior, appearance, and insight. Seven items are rated on a five-point Likert scale, whereas the remaining four are rated on a nine-point scale. The total scores range from 0 to 44, with higher scores reflecting greater manic symptom severity. The Turkish adaptation was validated by Karadağ et al. (28), who demonstrated its reliability and validity in clinical populations.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eHamilton Depression Rating Scale (HAM-D)\u003c/strong\u003e:\u0026nbsp;The HAM-D, originally developed by Hamilton, is a clinician-rated scale designed to assess the severity of depressive symptomatology. In this study, the 17-item version was employed, covering domains such as mood, guilt, suicidal ideation, sleep disturbances, agitation, anxiety, weight loss, and somatic complaints. The items are rated on either a three- or five-point scale, with higher scores reflecting greater severity of depressive symptoms. In clinical practice, scores between 16\u0026ndash;25 reflect mild depression, scores between 26\u0026ndash;40 indicate moderate depression, and scores above 40 indicate severe depression. The Turkish version has been validated and shown to be reliable by Akdemir et al. (29).\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eEdinburgh Bulimia Research Test (EBAT)\u003c/strong\u003e: The EBAT, also known as the Bulimic Investigatory Test, Edinburgh (BITE), was developed by Henderson and Freeman in 1987 (30) as a self-report questionnaire for assessing bulimia-related symptoms and eating attitudes. It consists of 33 items (36 questions in total due to subitems), the majority of which are scored dichotomously (\u0026ldquo;Yes/No\u0026rdquo;). Five items are reverse-scored to reduce response bias. In addition, six items evaluate symptom frequency and severity via graded response options. Total scores \u0026ge;20 indicate the presence of binge eating, scores between 10\u0026ndash;19 suggest abnormal eating attitudes, and scores \u0026lt;10 are considered nonpathological. The reported Cronbach\u0026rsquo;s alpha values are 0.87 for the symptom scale and 0.62 for the severity subscale. The Turkish validation study confirmed its psychometric adequacy in a sample of university students (31).\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eBarcelona Bipolar Eating Disorder Scale (BEDS)\u003c/strong\u003e: The BEDS was specifically developed to provide a brief, self-administered screening tool for the detection of eating disturbances in patients with BD (20). It comprises 10 items scored on a four-point scale (0\u0026ndash;3), with higher values reflecting greater severity of eating pathology. The item scores are summed to yield a total score, which represents the overall severity of ED symptoms. The scale was originally validated in Spanish populations by Torrent et al. (20) and subsequently adapted into French (21). The Turkish adaptation in the present study followed a rigorous translation\u0026ndash;back-translation process to ensure semantic and conceptual equivalence.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eDutch Eating Behavior Questionnaire (DEBQ)\u003c/strong\u003e: The DEBQ, developed by Van Strien et al. (32), is a 33-item self-report instrument assessing three dimensions of eating behavior: emotional eating (13 items), external eating (10 items), and restrained eating (10 items). Each item is rated on a five-point Likert scale ranging from \u0026ldquo;never\u0026rdquo; (1) to \u0026ldquo;very often\u0026rdquo; (5). Factor analyses of both the original and Turkish versions confirmed the three-factor structure. The reliability coefficients are high, with Cronbach\u0026rsquo;s alpha values reported as 0.95 for restrained eating, 0.94 for emotional eating, and 0.80 for external eating in Dutch samples. The Turkish version demonstrated comparable psychometric properties, with alphas of 0.91, 0.92, and 0.72 for restrained, emotional, and external eating, respectively (33).\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eBrief Psychiatric Rating Scale (BPRS)\u003c/strong\u003e: Originally developed by Overall and Gorham in 1962 (34), the BPRS is a clinician-administered scale designed to evaluate psychiatric symptom severity across a wide range of domains. The version employed in this study includes 18 items assessing symptoms such as anxiety, depression, hostility, suspiciousness, hallucinations, unusual thought content, conceptual disorganization, and emotional withdrawal. Each item is scored on a 7-point scale (0 = not present to 6 = extremely severe), yielding a total score ranging from 0--108. Scores between 15\u0026ndash;30 generally indicate mild symptomatology, whereas scores \u0026ge;30 suggest severe psychopathology. The Turkish validation study was conducted by Soykan in 1990 (35), confirming the instrument\u0026rsquo;s clinical utility.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eStatistical\u0026nbsp;\u003c/strong\u003e\u003cstrong\u003eanalysis\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eInternal consistency was evaluated via Cronbach\u0026rsquo;s alpha, and item\u0026ndash;total correlations as well as Cronbach\u0026rsquo;s alpha values if an item was deleted were calculated.

The results strongly support the use of the Turkish version of the BEDS as a valid and reliable instrument for identifying disordered eating behaviors in this population.\u003c/p\u003e\u003cp\u003eThe Barcelona Bipolar Eating Disorder Scale is a brief self-report instrument designed to assess disordered eating behaviors specifically within the context of bipolar disorder. It evaluates impulsive and emotion-driven eating tendencies, such as loss of control over eating, binge-like episodes, and eating in response to mood fluctuations. Rather than diagnosing a specific eating disorder, the BEDS captures the overall severity and frequency of eating-related disturbances that may emerge as part of affective instability and impulsivity in individuals with bipolar disorder. Therefore, establishing a valid and reliable version of such a scale for Turkish-speaking populations would increase its utility in both academic research and clinical practice, ultimately facilitating clinicians\u0026rsquo; ability to monitor and follow patients more effectively.\u003c/p\u003e\u003cp\u003eThe internal consistency of the Turkish BEDS was found to be high (Cronbach's alpha\u0026thinsp;=\u0026thinsp;0.821), which is comparable to the values reported in the original Spanish validation (0.79) (\u003cspan citationid=\"CR20\" class=\"CitationRef\"\u003e20\u003c/span\u003e) and the French version (0.82) (\u003cspan citationid=\"CR21\" class=\"CitationRef\"\u003e21\u003c/span\u003e). These results suggest that the scale maintains its reliability across different languages and cultural contexts. The item\u0026ndash;total correlations ranged between 0.31 and 0.64, confirming that all the items contributed meaningfully to the underlying construct. These findings suggest that the BEDS reliably captures a coherent dimension of eating pathology, as it manifests in BD.\u003c/p\u003e\u003cp\u003eExploratory factor analysis supported a unidimensional structure, with factor loadings ranging from 0.34\u0026ndash;0.72 and a single factor explaining 33.26% of the total variance. The Kaiser\u0026ndash;Meyer\u0026ndash;Olkin measure (0.85) and the significant Bartlett\u0026rsquo;s test (χ\u0026sup2; = 640.01, p\u0026thinsp;\u0026lt;\u0026thinsp;0.001) verified the adequacy of the data for factor analysis. This structure corresponds closely to the original validation, suggesting that the Turkish version preserves both the semantic and conceptual integrity of the scale.\u003c/p\u003e\u003cp\u003eOne of the problems with the scales used to assess psychiatric disorders is their length and/or the need for expert administration, which limits their clinical utility (\u003cspan citationid=\"CR20\" class=\"CitationRef\"\u003e20\u003c/span\u003e). In brief, self-administered screening measures are particularly valuable in clinical practice, where lengthy or interviewer-based instruments can be difficult to administer. Given the high comorbidity rates of BD and ED\u0026mdash;especially binge eating disorder and bulimia nervosa\u0026mdash;early detection of eating pathology in this population is essential (\u003cspan citationid=\"CR18\" class=\"CitationRef\"\u003e18\u003c/span\u003e). In line with this, the significant correlations observed between BEDS total scores and the emotional and external eating subscales of the DEBQ underscore the instrument's clinical sensitivity. The lack of correlation with restrained eating suggests that the BEDS focuses primarily on loss of control and emotion-focused eating rather than cognitively controlled dietary restriction.\u003c/p\u003e\u003cp\u003eThe inverse correlation with the Edinburgh Bulimic Investigation Test (BITE) may be attributed to differences in scoring direction and item framing between the two scales. Considering this context, the results are consistent with previous evidence linking BD to binge-eating symptomatology (\u003cspan citationid=\"CR24\" class=\"CitationRef\"\u003e24\u003c/span\u003e). Furthermore, the lack of correlation between BEDS scores and the YMRS, HAM-D, or BPRS supports the scale's discriminant validity and suggests that eating disorders are not merely reflections of existing manic, depressive, or general psychopathological states. This finding suggests that such tendencies may represent enduring personality traits rather than transient mood-related phenomena in BD patients.\u003c/p\u003e\u003cp\u003eFrom a clinical perspective, the BEDS offers several practical advantages. Its brevity, clarity, and self-reported design make it suitable for use in time-constrained psychiatric settings (\u003cspan citationid=\"CR21\" class=\"CitationRef\"\u003e21\u003c/span\u003e). Unlike more extensive instruments such as the DEBQ or BITE, the BEDS specifically targets impulsive and emotionally reactive eating behaviors, which are common yet often overlooked in BD (\u003cspan citationid=\"CR17\" class=\"CitationRef\"\u003e17\u003c/span\u003e). Early identification of these symptoms is crucial, given the established links between BD\u0026ndash;ED comorbidity and poorer clinical outcomes, including earlier onset, increased episode frequency, elevated suicidality, and reduced psychosocial functioning (\u003cspan citationid=\"CR24\" class=\"CitationRef\"\u003e24\u003c/span\u003e). The Turkish adaptation provides clinicians with a culturally appropriate and psychometrically sound tool for identifying such comorbidities. Routine application may enhance early intervention and contribute to a more integrative understanding of BD by accounting for both affective and behavioral dysregulation.\u003c/p\u003e\u003cp\u003eCultural and linguistic adaptation is vital when psychological instruments are translated, as eating behaviors are strongly influenced by cultural norms regarding food, body image, and emotional expression. The successful validation of the Turkish BEDS demonstrated that the construct of impulsivity-driven, emotionally mediated eating is recognizable and clinically relevant in the Turkish population. This achievement not only improves diagnostic precision in local practice but also promotes cross-cultural comparability in international BD and ED research.\u003c/p\u003e\u003cp\u003eThis study has several strengths. Compared with previous validation efforts, the present study included a relatively larger sample size (100 BD patients and 129 healthy controls). Moreover, the diagnostic accuracy of the clinical sample was ensured through the use of structured interviews (SCID-5), thereby increasing methodological rigor. Nevertheless, several limitations must be acknowledged.\u003c/p\u003e\u003cp\u003eFirst, the patient sample consisted solely of individuals with BD type I, limiting generalizability to other BD subtypes, such as type II or cyclothymia. Second, the cross-sectional design prevents assessment of the scale\u0026rsquo;s sensitivity to longitudinal changes or treatment outcomes. Third, although the sample size was adequate for psychometric testing, future studies should include larger and more diverse samples to examine measurement invariance across gender, age, and illness stage. Third, although the sample size was adequate for psychometric testing, future studies should include larger and more diverse samples to examine measurement invariance across gender, age, and illness stage.\u003c/p\u003e\u003cp\u003eIn summary, the Turkish version of the Barcelona Bipolar Eating Disorder Scale has excellent psychometric properties, including high internal consistency, a coherent factor structure, and meaningful convergent validity. The scale effectively identifies impulsive and emotion-driven eating behaviors that are prevalent yet often underrecognized among individuals with bipolar disorder. Its brevity and ease of administration make it well suited for both clinical practice and research. Integrating the BEDS into routine assessment protocols may facilitate early detection of comorbid eating disturbances and enhance comprehensive care and prognosis in patients with bipolar disorder.\u003c/p\u003e"},{"header":"Declarations","content":"\u003cp\u003e\u003cstrong\u003eAcknowledgements:\u0026nbsp;\u003c/strong\u003eBefore starting this study, permission was obtained from the ethics committee of the Scientific Research Committee of Dışkapı Education and Research Hospital (fund number: 58/14, Date:07/01/2019).

These patients were diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), and the Structured Clinical Interview for DSM-5 (SCID-5). Sociodemographic forms, the Turkish Vesion of BEDS, the Young Mani Rating Scale (YMRS), the Hamilton Depression Rating Scale (HAM-D), the Brief Psychiatric Rating Scale (BPRS), the Bulumic Investigatory Test Edinburgh (BITE), and the Dutch Eating Behavior Questionnaire (DEBQ) were used to assess validity and reliability.\u003c/p\u003e\u003ch2\u003eResults\u003c/h2\u003e\u003cp\u003eNo statistically significant differences were found between the patient and control groups regarding the total and subscale scores of the BITE, BEDS, and DEBQ. The correlation coefficient between each item and the total score ranged from 0.313\u0026ndash;0.644. Cronbach's alpha for the scale was 0.821. The removal of any items from the original scale did not lead to an improvement in Cronbach\u0026rsquo;s alpha. The BEDS score was found to be significantly correlated with the BITE score, DEBQ total score, emotional eating score, and external eating score (p\u0026thinsp;\u0026lt;\u0026thinsp;0.001).
