This project will fund efforts to expand both my theoretical and applied knowledge in the area of psychotherapy intervention delivery. I will pursue work with intervention approaches and populations to which I have had very little exposure as a clinical health psychologist in an academic setting. I will work towards three primary goals. First I will broaden my perspective on the delivery of psychological intervention by enhancing my understanding of the theoretical underpinnings and practical application of two specific psychotherapies, Dialectical Behavior Therapy and Acceptance and Commitment Therapy. Second, I will expand my understanding of current best practices for the treatment of individuals with chronic and persistent mental illness and will explore interventions that are effective for common psychological problems of children/adolescents. Finally, I will broaden my exposure to well-designed clinical trials designed to test the efficacy of selected psychological interventions. In order to address these goals, I will make one three-day trip to each of three carefully identified sites. Two of these sites are clinical and one is academic in nature. During these visits, I will immerse myself in a range of relevant clinical and research activities, such as direct observation of therapy groups, attendance at clinical and research team meetings, and meetings with mental health staff. This project will provide the opportunity for me to translate theory into practice and will enable me to broaden my intellectual perspective in the field of clinical psychology.
