Abstract

Purpose: Disordered eating patterns, particularly binge eating, are prevalent in Hispanic samples, yet the biopsychosocial risk factors remain understudied in minority populations. The relationship between diet self-efficacy and bulimic symptoms has been established in non-Hispanic white samples but not yet in Hispanics. This study sought to identify the direct role of diet self-efficacy on eating disorder risk and symptomology in a multicultural Hispanic sample, and to investigate the potential indirect relations among diet self-efficacy, self-esteem, body mass index (BMI), and eating disorder risk and symptomology in Hispanics and non-Hispanic whites.

Methods: The present study surveyed 1339 college students from diverse ethnic backgrounds. Participants completed four standardized scales to assess acculturation, diet self-efficacy, global self-esteem, and eating disorder symptomology and risk. Self-reported height and weight were used for BMI calculations, and the data were analyzed in a robust maximum-likelihood structural equation modeling (SEM) framework.

Results: The findings highlighted diet self-efficacy as a predictor of eating disorder risk and symptomology. Diet self-efficacy partially explained the covariation between self-esteem and eating disorder risk and symptomology, and between BMI and eating disorder risk and symptomology for the entire sample.

Conclusion: Diet self-efficacy emerged as an important construct to consider in developing eating disorder prevention and treatment models.
