Design outcomes

Primary

Measure	Time frame
Psychological flexibility, the core construct of acceptance-commitment therapy, is measured using the CompACT (Comprehensive Assessment of Acceptance and Commitment Therapy Processes). A pre/post survey is carried out for all participants in the group psychotherapy before the start and after the end of the intervention (pre/post measurement points). In the intervention group, the pre-post surveys are the same as the T1 and T2 measurement points. In the waiting control group, the CompACT is also recorded three weeks before participation in the group psychotherapy (T1). This means that the pre-/post-survey times are T2 and T3. In the control group, psychological flexibility is measured at two points in time, at T1 and T2, three weeks apart, which corresponds to the duration of the ACT intervention.	—

Secondary

Measure	Time frame
At all measurement points in the intervention group, waiting control and control group, depression and anxiety symptoms are measured using the depression module of the Patient Health Questionnaire (PHQ-9) and the Generalized Anxiety Disorder (GAD-7) module. Only post-ACT intervention, after the last session, a questionnaire specially developed for the study will be used to evaluate the metaphors used in group psychotherapy.	—
