Abstract

Background:

Understanding eating behaviors in Latin American contexts is crucial, given the current epidemic of obesity among adolescents in this region.

Objective:

The study aimed to analyze the psychometric properties of the Addiction-Like Eating Behavior Scale (AEBS) in adolescents from Peru.

Methodology:

The study was psychometric in nature, conducted with a sample of 1,249 adolescents from coastal (Chimbote, n = 841) and jungle (Tarapoto, n = 408) cities in Peru. An exploratory factor analysis (EFA) was performed, and a scree plot was used to determine the factors. Additionally, a confirmatory factor analysis (CFA) was conducted to evaluate the goodness-of-fit indices used for structural validity, and the reliability of the Peruvian version of the AEBS was determined using McDonald's Omega.

Results:

The EFA reported the presence of three factors (KMO = 0.80 and p < 0.000). Furthermore, the CFA reported adequate fit indices (χ² = 881.401; CFI = 0.957; TLI = 0.946; RMSEA = 0.074; and SRMR = 0.066) confirming the structure. The reliability was acceptable, with ω > 0.65 for all factors.

Conclusion:

The adapted version of the AEBS is valid and reliable for use with Peruvian adolescents.

Self-Discrepancy Theory

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.
