The reliability and validity of the Swedish version of Body Shape Questionnaire

• 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 .94 to .97, and high split-half reliability (above .93). Furthermore, it showed high validity by correlating highly with the body dissatisfaction subscale of the Eating Disorders Inventory (r=.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.
