Abstract

Objective:The aim of this study was to translate, cross-culturally adapt, validate the content, and test the reliability of the Spanish version of the Weight Efficacy Lifestyle Questionnaire to assess self-efficacy in dietary behavior among Mexican adolescents.Methods:The study consisted of two phases. The first phase included the translation and cross-cultural adaptation of the Weight Efficacy Lifestyle Questionnaire (WEL), following the six steps proposed by Beaton. In the second phase, content validity (linguistic clarity, practical relevance, and theoretical significance) was assessed by obtaining the content validity coefficient (CVC), and reliability-consistency was assessed using Cronbach’s alpha and intraclass correlation coefficient after application to the target population. Results: The translation and adaptation of the instrument by the expert committee allowed subtle adjustments in the Spanish version for Mexican adolescents. The content validity coefficient of the items ranged from 0.81 to 0.99, the overall content validity coefficient was 0.96, the overall Cronbach’s alpha obtained was greater than 0.70, and the intraclass correlation coefficient was greater than 0.75, with all 20 scale items remaining intact.Conclusion: The translated and adapted Spanish version of the Weight Efficacy Lifestyle Questionnaire demonstrated adequate reliability and content validity, allowing its use in the Mexican population. It can be used by health professionals at different levels of care. The proposed version of the WEL questionnaire can help health professionals develop strategies based on a preventive approach, conduct initial assessments of dietary self-efficacy, and develop programs or interventions aimed at the treatment and control of obesity in Mexican adolescents.
