Abstract:
Popular measures of psychological flexibility (PF), such as the Acceptance and Action Questionnaire (AAQ-II) and Brief Experiential Avoidance Questionnaire (BEAQ) have been criticized for questionable psychometric properties. The critiques include poor divergent validity with negative emotionality and disregarding PFs theoretical definition of flexible contact with the present moment while acting in the service of chosen values. Recently, the Personalized Psychological Flexibility Index (PPFI) has been proposed as an alternative self-report measure of PF that attempts to address these issues above. The current study sought to test the psychometric properties of the PPFI in a large sample from the general population who completed a cross-sectional survey. Exploratory factor analysis indicated that the Persian version of the PPFI has a three-factor structure mapping onto the avoidance, acceptance, and harnessing subscales. Confirmatory factor analyses supported a three-factor solution, showed a good model fit, and good internal consistencies. Test of incremental validity indicated the PPFI explained more variance in 10 of 15 outcomes than the BEAQ or AAQ-II.
