This study examined shifts in adolescents' attachment relationships with parents and peers during a 7-week wilderness therapy program. Ninety-six adolescents, aged 14-17, completed three quantitative measurements evaluating attachment relationships with mother, father and peers pre and post treatment. Adolescents reported improved attachment relationships in terms of decreased anger and increased emotional connection towards parents. Results also showed adolescents' more troubled attachment relationships in terms of trust and communication with parents by the end of treatment. Adolescents reported similarly mixed results in both a positive and negative direction regarding peers. These findings indicate the complexity of parent-adolescent relationships particularly considered in the context of out-of-home care and point to the importance of continued exploration in this area.
