The main goal of the study is to explore the relationship between coping styles and vulnerability to eating disorders in a sample of adolescent girls, according to their age. The sample comprises 1396 girls, aged 13 to 18, who completed the Eating Disorders Inventory-3 (EDI-3) and the Adolescent Coping Scale (ACS). The regression analysis shows that the coping strategy most closely linked to the likelihood of developing an ED in all age groups is Intropunitive Avoidance. The scales of the Intropunitive Avoidance dimension that have the most explanatory power are Tension Reduction and Self-Blame. Girls aged 13 and 17 are identified as the highest risk groups. Physical and social changes are proposed as the hypothetical explanation for the difference between age groups. Emphasis is placed on the need for specific prevention programs for adolescents, particularly those at high risk.
