Meta-analysis of Specific Music Therapy Measures and Their Implications for the Health Care System.
The purpose of the activity reported in this article was to conduct an exhaustive search of the Journal of Music Therapy, filter the articles on the desired parameters, and organize data for analysis and interpretation. Specifically, the researcher studied whether (a) there was a significant difference in physiological measures, (b) there was a significant difference in quality of life, (c) there was a significant difference in satisfaction levels, (d) there was a significant difference in pain reduction, (e) there was a significant difference in procedural length, (f) there was a significant difference in length of stay, and (g) whether the overall effect size and 95% confidence level support the recommendation of music therapy in the health care setting. Twenty-four studies met criteria for inclusion in the systematic review. Results revealed an overall effect size of d = 0.61. However, results of the 95% confidence interval included 0, which suggests that there may not be a statistically significant difference in the health care setting on desired measures. Further results and implications are discussed within the article.
