Background: Body-focused repetitive behaviours (BFRBs) such as skin picking and hair pulling are frequent but under-diagnosed and under-treated psychological conditions. As of now, most studies use symptom-specific BFRB scales. However, a transdiagnostic scale is needed in view of the high co-morbidity of different BFRBs. Aims: We aimed to assess the reliability as well as concurrent and divergent validity of a newly developed transdiagnostic BFRB scale. Method: For the first time, we administered the 8-item Generic BFRB Scale (GBS-8) as well as the Repetitive Body Focused Behavior Scale (RBFBS), modified for adults, in 279 individuals with BFRBs. The GBS-8 builds upon the Skin Picking Scale-Revised (SPS-R), but has been adapted to capture different BFRBs concurrently. A total of 170 participants (61%) were re-assessed after 6 weeks to determine the test–retest reliability of the scale. Results: Similar to the SPS-R, factor analysis yielded two dimensions termed symptom severity and impairment. The test–retest reliability of the scale was satisfactory (r =.72, p<.001). Concurrent validity (r =.74) with the RBFBS was good (correlational indexes for concurrent validity were significantly higher than that for discriminant validity). Discussion: The GBS-8 appears to be a reliable and valid global measure of BFRBs. We recommend usage of the scale in combination with specific BFRB scales to facilitate comparability across studies on obsessive-compulsive spectrum disorders. [ABSTRACT FROM AUTHOR] |
