The study of attachment is a valuable theoretical framework to understand the influence of parents and friends on the evolution and development of adolescents. This study aimed to determine parents' and peers' attachment style, the relationship between parents' and peers' attachment and body dissatisfaction in adolescents with eating disorders (ED), and to compare it with a control group. The sample consisted of 260 adolescents (Mage = 15.35, SDage = 1.461): a control group consisting of 129 non-clinical subjects and an ED group composed by 131 adolescents diagnosed with ED who attended five ED units located in different regions of Spain. They completed the Body Shape Questionnaire (BSQ-34) and the Inventory of Parent and Peer Attachment (IPPA). Adolescents with ED have less trust with their parents, worse communication with their parents and peers, and greater alienation with fathers and peers. The results showed a statistically significant relationship between parents' attachment and body dissatisfaction in both groups. In ED group, peers' alienation was positively correlated to body dissatisfaction. Parental attachment and alienation feelings with peers could influence body dissatisfaction in ED adolescents.
