The Weight Influenced Self-Esteem Questionnaire (WISE-Q): factor structure and psychometric properties.
Weight-based self-esteem (WBSE) is hypothesized to be the core cognitive feature of eating disorders. The Weight Influenced Self-Esteem Questionnaire (WISE-Q) was designed to measure the influence of a negatively perceived body image on multiple dimensions of self-esteem, which we believe to be one aspect of WBSE. Study 1 sought to determine the factor structure of the WISE-Q as well as to examine the reliability and concurrent validity of WISE-Q scores among eating disorder and undergraduate student participants. In Study 2, validity was further investigated by examining changes in WISE-Q scores with treatment. The WISE-Q has two factors representing generalized and expected WBSE. Evidence of internal and test-retest reliability was found. Also, the pattern of correlations between WISE-Q scores and other constructs was in line with predictions. As expected, WISE-Q scores improved with treatment yet remained high.
