Abstract

Psychometric properties of the Swedish version of the Body Shape Questionnaire (BSQ) were examined using data from three samples: (1) a sample from the general population (n= 1157), (2) a student sample (n= 124) and (3) a clinical sample (n= 90). Analyses showed that a single factor solution might be a reasonable solution as 32 of the 34 items loaded heavily on the first factor. The derived short 14-item version of the BSQ also showed a coherent structure with all the items loading on one single factor. The BSQ showed high test-retest reliability, very high internal consistency, ranging from 0.94 to 0.97, and high split-half reliability (above 0.93). Furthermore, it showed high validity by correlating highly with the body dissatisfaction subscale of the Eating Disorders Inventory (r= 0.72 and higher), and high discriminant validity. Thus, the Swedish version of the BSQ showed good concurrent and discriminant validity as well as high reliability.
