Objectives. This study aimed to assess the psychometric properties of the Czech adaptation of the Comprehensive Assessment of Acceptance and Commitment Therapy Processes (CompACT) questionnaire, which assesses three psychological flexibility processes consistent with the ACT Triflex. Participants. The data was collected from 299 participants (209 females, 87 males, and 3 other/did not specify) aged 18 to 70 years (M = 29.27, SD = 10.51). Statistical analyses. Confirmatory factor analysis (CFA) with a robust maximum likelihood estimation method was used to assess factor validity. Furthermore, the authors used structural equation modelling (SEM) to assess convergent, concurrent, and incremental validity. Finally, the authors used McDonald’s omega for the assessment of internal consistency. Results. The CFA showed that the original 23-item model did not fit the data well. Through a series of confirmatory factor analyses and modification indices, the authors found an alternative 17-item model. However, the model did not fit with the data acceptably. Moderate to high correlations (-.81 to -.54) between the latent factors of the 17-item CompACT and the Action and Acceptance Questionnaire-II (AAQ-II) indicate good convergent validity. Low to moderate correlations (-.64 to -.33) between the latent factors of the 17-item CompACT and a shorter version of the Depression Anxiety Stress Scale (DASS-21) and Satisfaction With Life Scale (SWLS) indicate acceptable concurrent validity. Partial regression coefficients of the CompACT latent factors were not alongside the AAQ-II questionnaire significant predictors of distress outcomes. Of the CompACT latent factors, only the Valued Actions subscale was a significant predictor of subjective well-being, indicating the poor incremental validity of CompACT over the AAQ-II. The questionnaire had good internal consistency, with McDonald’s omega ranging from .75 to .85.
