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.
