A German version of the Caregiver Skills scale for caregivers of patients with anorexia nervosa

Objective To investigate acceptance, reliability, convergent validity, factor structure and sensitivity to change of a German translation of the Caregiver Skills (CASK) scale measuring skills related to caring for patients with eating disorders. Methods Two hundred and thirty‐three parents (76% female) of adolescent patients (mean age 15.1) with anorexia nervosa (AN) completed the 27 items of the CASK. We calculated item/scale characteristics, internal consistencies and bivariate correlations with other measures of caregiving burden. We evaluated goodness‐of‐fit of the 6‐factor model using confirmatory factors analysis and explored the sensitivity to change following two skills‐based trainings. Results The fit of the 6‐factor model was acceptable (Root Mean Square Error of Approximation: 0.077, Standard Root Mean Square Residual: 0.080). Cronbach's alpha was excellent for the total (.94) and acceptable for all subscales (0.73–0.85). The total CASK score was 68.04 (max. 100) showing relatively high self‐rated caregiver skills. Non‐completion rates of most items were low (
