Aim and Background: Being overweight, a severe public health problem, is associated with experimental avoidance. This study aims to examine the reliability and validity of the Turkish version of the Acceptance and Action Questionnaire for weight-revised (AAQW-R) in people with a BMI above 25
Methods: The sample consisted of 207 participants. The participants who gave informed consent were asked to fill out a demographic form, AAQW-R, AAQ-2, WSSQ, and GHQ. Internal consistency and item-total correlation were evaluated using Cronbach’s alpha coefficient. CFA was used to test the factor structure. The temporal stability was assessed with the test-retest method. AAQW-R has significant correlations with BMI, AAQ-2, WSSQ, and GHQ.
Results: CFA demonstrates a three-factor structure (χ2 = 57.0, df = 31; RMSEA = 0.0714; RMSEA 90% CI lower bond=0.0411, RMSEA 90% CI upper bond=0.100, CFI = 0.968; TLI = 0.954). AAQW-R and subscales of AAQW-R have significant correlations with AAQ-2, AAQW-R, BMI, WSSQ, and GHQ (p
