Abstract

This paper deals with the different risk scales of eating disorder in adolescents. The main objective is to create a scale to measure the risk of developing eating disorders using social and behavioral variables. The trial sample included 605 adolescents, aged 12–17 years (M = 14.27; SD 1.44), randomly selected from several centers who requested to participate in a health program. After using the principal component extraction method (PCA) with adequate internal consistency and reliability, and with a total explained variance of 60%, factor analysis showed five factors: satisfaction with body image, self-esteem, use of social networks, negative relationship with food, and image and social recognition. Pearson’s correlation coefficients between our scale and reference scale (SCOFF) factors provided information on converging validity. However, the Cronbach’s alpha values for dimensions 3 and 4 failed to reach the desired scores, and it was noted that not all dimensions had the same number of elements. Therefore, future interventions and proposals to develop a stronger scale are proposed. Despite the drawbacks, our findings provide a solid foundation for further analysis to find the most reliable method of analysis possible in this innovative area. We believe that this scale can help both health and education professionals to develop effective interventions.
