Croatian Translation and Initial Psychometric Validation of the Negative Behaviors in Health Care Questionnaire

This cross-sectional study aimed to produce an adapted Croatian version and validate the Negative Behaviors in Health Care Questionnaire. Methods: The translation, cultural adaptation, and psychometric evaluation of the questionnaire were approached. Clinical specialists and qualified bilingual speakers participated in both forward and backward translation. Face validity was tested. The survey's original developer approved the final version. The reliability of the questionnaire was assessed using the test-retest method and Cronbach alpha coefficient. Exploratory and confirmatory factor analyses and assessments of divergent and convergent validity were conducted for the questionnaire. The collected data were analyzed using SPSS 21.0 and R program version 3.5.2. for Windows. Results: A 5-factor structure was obtained, just like the original version of the questionnaire, which was confirmed by CFA – although not all fit coefficients were satisfactory. Internal consistency reliability was found to be high and test-retest reliability was satisfactory. Conclusions: The adapted, translated, and validated survey provides a valuable tool for assessing lateral and vertical aggression between and towards nurses regarding contributing factors, frequency, severity, uses of aggression, and fear of retaliation.
