This thesis discusses the biological, social, and cognitive transitions during adolescent development. Common difficulties that are associated with adolescent girls are reviewed, including identity development, self-esteem, and psychological states including depression and anxiety. An overview of strategies for working with adolescents that use existentialism and spirituality as a theoretical approach is offered along with the rationale for choosing this approach. Prevention programs that show demonstrated efficacy are summarized, and finally a proposed prevention program, O.W.L.S.: Circle of Wisdom, is introduced. |
