Evaluating the psychometric characteristics of the Work-related Acceptance and Action Questionnaire (WAAQ) in a sample of healthcare professionals

The Work-related Acceptance and Action Questionnaire (WAAQ) has been developed to assess psychological flexibility in occupational settings. The aim of this study was to evaluate reliability and validity of the Swedish translation of WAAQ in a sample of 184 healthcare professionals. A principal component analysis supported a one-factor-solution, explaining 53.8% of the overall multivariate variability. WAAQ showed good internal consistency (Cronbach's alpha 0.85) and good test-retest reliability (ICC = 0.85). Validity was assessed by analysing the relationship between WAAQ and other work-related constructs. Spearman's rank correlations illustrated a significant negative relationship between WAAQ and perceived stress and a significant positive correlation with work engagement. Results from the study are consistent with previous studies on WAAQ, supporting the use of the Swedish translation of the instrument among healthcare professionals.
