| Abstract: | Acceptance and Commitment Therapy (ACT) makes it possible to improve the effectivity of bariatric surgery. Psychological flexibility is the central proces within ACT. To measure this construct, psychometrically sound instruments are needed. The Avoidance and Fusion Questionnaire for Youth (AFQ-Y) is a reliable and valid self-report measure for psychological flexibility, but has never been evaluated in a bariatric surgery candidates population. In the present study the psychometric properties of the AFQ-Y were investigated in a population of Dutch adult bariatric surgery candidates (N = 34). Patiënts received a survey containing the Dutch version of the AFQ-Y and instruments to measure theoretically related constructs as psychological flexibility, facets of mindfulness, anxiety, depression, mental- and physical health. An exploratory factor analysis replicated the previously found one-factor solution measuring psychological inflexibility. Additional analyses revealed that the AFQ-Y has satisfactory psychometric properties, and can be used to measure psychological inflexibility in a population of adult bariatric surgery candidates. Furthermore, the AFQ-Y showed incremental validity beyond measures of facets of mindfulness and psychological flexibility, in explaining mental health and psychological symptoms. The possibilities for using the AFQ-Y in postoperative support programs and psychological screening for bariatric surgery, as well as strengths and weaknesses of the present study are discussed. |
