Abstract:
Introduction: This study aimed to evaluate the validity and reliability of the Multidimensional Body Image Scale (MBIS), a seven-factor, 62-item scale developed for Malaysian female adolescents. This scale was evaluated among male and female Malaysian university students. Methods: A total of 671 university students (52.2% women and 47.8% men) completed a self-administered
questionnaire on MBIS, Eating Attitude Test-26, and Rosenberg Self-Esteem Scale. Their height and weight were measured. Results: Results in confirmatory factor
analysis showed that the 62-item MBIS reported poor fit to the data, ²/df = 4.126, p < 0.001, CFI = 0.808, SRMR = 0.070, RMSEA = 0.068 (90% CI = 0.067, 0.070).
After re-specification of the model, the model fit was improved with 46 items remaining, ²/df = 3.346, p < 0.001, CFI = 0.903, SRMR = 0.053, RMSEA = 0.059
(90% CI = 0.057, 0.061), and the model showed good fit to the data for men and women separately. This 46-item MBIS had good internal consistency in both men (Cronbach’s alpha = 0.88) and women (Cronbach’s alpha = 0.92). In terms of construct validity, it showed positive correlations with disordered eating and body weight status, but negative correlation with self-esteem. Also, this scale discriminated well between participants with and without disordered eating. Conclusion: The MBIS-46 demonstrated good reliability and validity for the
evaluation of body image among university students. Further studies need to be conducted to confirm the validation results of the 46-item MBIS.
