This report presents a comprehensive research proposal for a randomized controlled trial (RCT) investigating the efficacy of music therapy in managing generalized anxiety disorder (GAD) among adolescent school students. The proposal begins with an executive summary highlighting the prevalence of anxiety disorders, particularly GAD, and the potential of music therapy as a non-pharmaceutical intervention. It outlines the study's aims and objectives, emphasizing the need to determine music therapy's impact on GAD prevalence and severity. The background and rationale section provides a detailed overview of GAD, its symptoms, diagnostic criteria, and prevalence in the Australian population. It also reviews existing literature on the pathophysiology of anxiety disorders and various treatment modalities, including cognitive behavioral therapy and pharmacological interventions. The proposal then describes the research plan, including the hypotheses, study design (RCT), study population, exposure measure (music therapy), outcome measures, statistical analysis, and anticipated outcomes. The study hypothesizes that music therapy will reduce the severity of GAD symptoms and prevent relapse. The report concludes with a list of references.
