Objectives:
The aim of the study was to translate and validate the Polish version of the Comprehensive Assessment of Acceptance and Commitment Therapy Processes (CompACT). This is a self-report questionnaire used to assess psychological flexibility, including three scales: "Openness to Experience", "Behavioural Awareness" and "Valued Action".
Methods:
A total of 791 individuals (423 women; 53.5%) aged 18-84, participated in the study. Additional data was gathered on life-satisfaction, the level of depression, anxiety and stress, psychological inflexibility, cognitive fusion, contact with present moment, self-perception, committed action, and valued living as the source of theoretical validity.
Results:
The internal structure of the full 23-item version was not confirmed (analogically as in the studies on the original version). The internal structure of the shorter 18-item version of the CompACT was confirmed, and a new 9-item version was proposed. Both versions (18-item and 9-item) exhibited good psychometric properties, incremental validity and measurement invariance across gender.
Conclusions:
CompACT-18 and CompACT-9 are reliable and valid tools to measure psychological flexibility and its three components.
