The purpose of this study was to analyze the existing researches utilizing
meta-analysis on evaluating the effect of music used in general medical
settings. For this study, the total of 220 variables was derived from 58
studies conducted between 2000 and 2015. And total of 220 variables were
divided into research background, types of medical services, music selection,
dependent variables and intervention time. The results indicated that the
overall mean effect size was -0.48, Second, the effect size of cardiothoracic
surgery was the most effective(-1.13) but there was no statistical difference
compared to the other medical services. Third, with music selection, the
effect size of music selected by patients was larger than the effect size of
music selected by researchers. However, there was no significant statistical
difference. Fourth, with dependent variables, the effect size of psychological
variables was the largest(-1.16). Finally, with intervention time, music used
in pre-operation was the most effective(-1.16), and there was a significant
statistical difference.
