Testing the Model of Psychological Flexibility in the Serbian Cultural Context: The Psychometric Properties of the Acceptance and Action Questionnaire

Summary/Abstract: The aim of this study was to examine the theoretical model of psychological flexibilityproposed by creators of Acceptance and Commitment Therapy. To do this, we investigated thestructural and convergent validity of the Acceptance and Action Questionnaire – II, translatedinto the Serbian language. The study was performed on 1781 Serbian speaking adults. Bymethods of robust confirmatory factor analysis, two models have been tested. The best fit wasachieved with the data-driven model constructed by adding three pairs of correlated residualsto the original hypothesized model of latent structure. This model demonstrated it`s structuralinvariance across samples divided by gender and by previous experience with servicesprovided by mental health professionals. Excellent convergent validity of the scale wasdemonstrated through adequate correlations with indicators of subjective well-being, styles ofemotional regulation, and coping strategies. Our findings suggest that the Serbian adaptationof the Acceptance and Action Questionnaire – II is a valid and reliable measure of behavioralavoidance, implicating that the construct of psychological flexibility has been demonstrated asconceptually similar to those previously found across various languages and cultural contexts
