Validity and Reliability of the Acceptance and Action Questionnaire-II: Latvian Version

Abstract

The objective of this study was to assess the psychometric properties of the Latvian version of the Acceptance and Action Questionnaire-II (AAQ-II), measuring psychological flexibility described as the ability to act according to chosen values while consciously being in contact with subjectively unpleasant present moment experiences. The scale provides a single score across 7 items. The original AAQ-II was translated to Latvian and then back to English. The Satisfaction with Life Scale, Flourishing Scale and Meaning in Life Questionnaire was applied for testing the convergent validity of the AAQ-II. Participants of the study were 191 people, ranged in age from 19 to 68 (159 women, mean age M = 30.62, SD = 9.50). Reliability analysis, exploratory and confirmatory factor analysis (EFA and CFA) of the scale were performed. EFA indicated a one-factor structure. Results showed that the Latvian version of AAQ-II has good psychometric properties and convergent validity. Testing of the original model by CFA resulted in acceptable fit indices.
