Music intervention in patients undergoing hematopoietic stem cell transplantation: A systematic review and meta-analysis.

AIMS: To explore whether music intervention improves the quality of life (QOL) of patients undergoing hematopoietic stem cell transplantation (HSCT) and to evaluate its impact on patients' symptoms of depression/anxiety and fatigue. METHODS: This systematic review and meta-analysis was conducted in accordance with the Preferred Reporting Items of Systematic reviews and Meta-Analyses (PRISMA) guidelines. The databases PubMed, Cochrane CENTRAL, and EMBASE were searched from inception to September 30, 2022. The search strategy used a combination of the keywords "music" and "hematopoietic stem cell transplantation" or "HSCT." The outcomes assessed were QOL, depression and anxiety, and fatigue. Pooled standardized mean differences with 95% confidence intervals were calculated to compare the outcomes between the music intervention and control groups. Heterogeneity across the studies was assessed using a chi-square-based test, and the I2 and Q statistics. RESULTS: Meta-analysis of the included study population showed that music intervention for patients undergoing HSCT was associated with patients' improved QOL, and resulted in reduced depression/anxiety and fatigue compared to patients without music intervention. CONCLUSION: Music intervention benefits HSCT outcomes, including better QOL, less depression/anxiety, and less fatigue postoperatively. Future trials with larger samples are still warranted to strengthen the evidence supporting the benefits of music intervention in this patient population.

Preliminary Assessment of Individual Zone of Optimal Functioning Model Applied to Music Performance Anxiety in College Piano Majors.

Individual zone of optimal functioning (IZOF) is a psychological model studied and applied to quantify athletes' anxiety and predicts their achievement in sports competitions. This study aimed to determine the application of the IZOF model to evaluate music performance anxiety (MPA) in pianists because the causes of anxiety in athletes and musicians may be similar. A total of 30 college-level piano-major students were included in the study, and the anxiety level in performance was scored by the Competitive State Anxiety Inventory-2 questionnaire. In the first phase, participants recalled and self-scored the four important performances in the past year. Notably, seven piano teachers scored the performances. Both results were combined to identify the individual IZOF zone. Each student showed different anxiety scores for cognitive state anxiety (CA), somatic state anxiety (SA), and self-confidence (SC). In the second phase, all participants scored their anxiety level 1 day before the final performance, and the same judges evaluated the performance immediately afterward. A total of 60% of the participants who had at least two subscales inside the IZOF received performance scores greater than 90. In conclusion, the IZOF model provides information for both piano teachers and pianists to help review their anxiety intensity and predict their performance scores to some extent.
