Validation of an Arabic version of the eating disorder inventory's body dissatisfaction subscale among adolescents, adults, and pregnant women.

ABSTRACT

INTRODUCTION: The 9-item Body Dissatisfaction Subscale (BDS) of the Eating Disorder Inventory is one of the most used tools for assessing thinness-oriented body dissatisfaction in research and clinical practice. However, no validated Arabic version of this scale exists to date. In this study, we sought to validate this instrument in three samples of native Arabic-speaking adolescents, adults, and pregnant women from Lebanon. METHODS: A total of 826 adults, 555 adolescents, and 433 pregnant women were included. To examine the factor structure of the BDS, we performed an exploratory factor analysis (EFA), using a principal component analysis via the FACTOR software on the first split-half subsample among Lebanese adults. We used data from the second split-half in the adult sample to conduct a Confirmatory Factor Analysis (CFA) through the SPSS AMOS v.29 software. That verified model was tested via CFA on adolescents and pregnant women. RESULTS: The EFA showed a bidimensional structure for the BDS, with all 9 items retained and divided into Factor 1 = Body Satisfaction (negatively-worded items) and Factor 2 = Body Dissatisfaction (positively-worded items). The CFA demonstrated invariable goodness-of-fit of the instrument in the three studied populations. McDonald's omega values were also adequate in the three samples, demonstrating its reliability. Moreover, the BDS showed invariance across sex among both adolescents and adults. Finally, higher BDS scores were correlated with more disordered eating, less body appreciation and less functionality appreciation, thus attesting to convergent validity of the scale. In addition, BDS scores correlated positively with depression and anxiety scores, indicating adequate patterns of divergent validity. CONCLUSION: In light of our findings, we endorse the use of the BDS by healthcare professionals in Arabic-speaking countries, in order to assess thinness-oriented body dissatisfaction in an appropriate and timely manner and ease early referral to a specialist, thereby preventing the deleterious health-related risks associated with this condition.

Body dissatisfaction is conceptualized as the pejorative subjective assessment of one's own body and discontent with the visual perception of it or with a particular feature of appearance, which is considered to be the most important global measure of stress related to the body. Body dissatisfaction has been found to be a predictor for the development of an eating disorder and occurs in individuals with different mental disorders. The 9-item Body Dissatisfaction Subscale (BDS) of the Eating Disorder Inventory is one of the most used tools for assessing thinness-focused body dissatisfaction, but has not yet been validated in Arabic. To this end, we aimed to translate and validate the Arabic version of the BDS in the present study, which would in turn facilitate research and improve clinical practices related to body dissatisfaction in Arabic-speaking nations. The present findings provide support for the psychometric properties of the Arabic version of the BDS for examining body dissatisfaction in Arabic-speaking adolescents, adults, and pregnant women in Lebanon.
