Development and Validation of a Body Image Assessment for Patient after Lower Limb Amputation: The Chinese Amputee Body Image Scale - CABIS

Rehabilitation professionals increasingly understand that psychological issue is an important key to achieve rehabilitation goals. Previous studies proved that body image has significant relationship with amputation rehabilitation, however, measurements on body image are not well stated. The aim of this study is to develop a Chinese version of Amputee Body Image Scale (CABIS). In this study, linguistic validity, content validity, test-retest reliability and construct-validity were examined. The 20 items CABIS showed with clear presentation and good content understandability. Expert panel agreed that CABIS covered major constructs in body image for patients after amputation. Moreover, test-retest reliability was found to be good (α= .857, p< .01). A three-factor structure can be extracted from factor analysis. These three factors were personal factor, social factor and functional factor. Furthermore, the internal consistency of the three individual factors and the overall CABIS were .852, .826, .636, and .694 respectively. The moderate internal consistency further confirmed that the items within each factor of the CABIS measure the same construct. Some psychometric properties of CABIS were collected. Further research on criterion-related validity and improvement on factor stability are recommended.
