Chilean Validation of the Operationalized Psychodynamic Diagnosis - Structure Questionnaire (OPD-SQ) for Personality Structure

Background: This is the validation of the Operationalized Psychodynamic Diagnosis - Structure Questionnaire (OPD-SQ) Methods: A clinical sample of 399 adults and a nonclinical sample of 50 healthy adults completed measures of depression, attachment, psychiatric symptomatology and distress. Internal consistency and concurrent validity were assessed. Test-retest and Reliable Change Index were also calculated, as the ability of the OPD-SQ to distinguish between the clinical and control subsamples. Results: High internal consistencies were found; significant differences between clinical and non-clinical samples, and significant associations with psychiatric symptomatology, depression and psychological distress. Conclusion: The Chilean OPD-SQ has good reliability, and discriminates between clinical and healthy samples.
