Abstract

Background: Disordered eating behaviors and body dissatisfaction are highly prevalent among adolescents and linked to negative health outcomes. While Hispanic adolescents appear to be at high risk of disordered eating and body dissatisfaction, validated tools for assessment of these health concerns among this population are lacking. Methods: This study used Confirmatory Factor Analysis to establish factorial validity for the Kids Eating Disorder Survey (KEDS) among a community sample of Hispanic adolescents. Internal consistency was measured by the Kuder-Richardson Formula 20 (KR-20). Results: Participants (N = 690) were Hispanic (100%) and female (53%), with a mean age of 12 years. After testing the psychometric properties of KEDS and implementing modifications, the resulting two-factor KEDS model (M-KEDS) showed acceptable fit (TLI = 0.98, CFI = 0.99, RMSEA = 0.06) for the Weight Dissatisfaction (renamed to Negative Weight Attitudes) and Purging/Restriction (renamed to Extreme Weight Control Behaviors) sub-scales and good internal consistency (KR-20 = 0.77). Conclusion: M-KEDS is a factorial valid instrument for assessing Extreme Weight Control Behaviors and Negative Weight Attitudes among Hispanic adolescents. Hispanics are among the fastest-growing racial/ethnic groups in the United States, warranting further research on negative weight attitudes and extreme weight control behaviors in this population.
