This nursing assignment critically appraises a randomized controlled trial (RCT) investigating the impact of music therapy on patients with depression, focusing on the study by Erkkila et al. (2019). The assignment evaluates the RCT's validity, addressing the PICO question: 'Does music therapy help in reducing depression among adults suffering from depressive disorder?'. The critique assesses the study's methodology, including randomization, sample size, blinding, and outcome measures such as the MADRS, HADS-A, and GAF scales. The report analyzes the statistical significance of the findings and discusses the generalizability of the results, considering the study's strengths, limitations, and implications for clinical practice, particularly in the context of a patient diagnosed with depression. The paper concludes that individual music therapy, when combined with standard care, is effective in reducing depressive symptoms in patients diagnosed with depression.
