A contribution to the validation of the Italian version of the Body Image Scale (BIS)

BACKGROUND: The Body Image Scale (BIS) is a 10-item mono-factorial scale, designed to capture distress and symptoms related to body image in cancer patients. This paper describes the conversion and psychometric evaluation of an Italian BIS version. METHODS: After the back-translation procedure, the Italian version of the BIS, together with the Hospital Anxiety and Depression Scale and the Short Form 36 Health Survey Questionnaire, have been administered to a sample of Italian adult females, surgically treated for a breast cancer at least one year before. RESULTS: Data on 109 participants were analyzed. The response rate was 92.5%. Response prevalence was adequate for 9 out of 10 items. Principal component analysis showed a one-factor structure. Internal consistency (Cronbach’s alpha =0.924) was good. The BIS correlated with the theoretically pertinent subscales of the other administered tools and was able to discriminate participants (discriminant validity) according to the undertaken surgical treatment (p = 0.031). CONCLUSIONS: This study supports the valid and reliable use also of the Italian version of the BIS.
