International group singing study with people with Parkinson's

We hypothesised that there would be no changes in health-related quality of life measures (PDQ-39) and mental well-being measures (DASS) after the six-month group singing intervention. We included 95 people living with a confirmed diagnosis of Parkinson's from three countries (Australia, South Korea and United Kingdom). MANOVA showed statistically significant multivariate effects of Time, Country, Time by Country and Time by Gender interactions on QoL. Follow-up univariate ANOVAs revealed main effects of Time on Stigma and Social Support domains of QoL; both improved. Further, MANOVA revealed a multivariate effect of Time on mental well-being; anxiety and stress significantly decreased from pre-test to post-test. This first international singing study with people with Parkinson’s demonstrated that group singing enhanced some aspects of quality of life and mental well-being. Participating in a weekly group singing program for a 6-month period positively impacted on social support, and feeling stigmatized, as well as reductions in anxiety and stress. The findings are encouraging and warrant further research.本研究假设：在为期六个月的团体歌唱干预后，健康相关生活质量量表（PDQ-39）与心理健康福祉量表（DASS）的测量结果不会发生变化。本研究共纳入来自澳大利亚、韩国与英国三个国家的95名经确诊的帕金森病患者。多元方差分析（MANOVA）结果显示，时间、国家、时间×国家交互作用以及时间×性别交互作用对生活质量（QoL）存在统计学意义显著的多元效应。后续单变量方差分析显示，时间对生活质量的病耻感与社会支持维度存在主效应，且两项指标均得到改善。此外，多元方差分析结果表明，时间对心理健康福祉存在多元效应：受试者的焦虑与压力水平在前测至后测阶段显著降低。这项针对帕金森病患者的首个国际性歌唱研究证实，团体歌唱可改善生活质量与心理健康福祉的部分维度。每周参与一次团体歌唱项目、持续六个月，可对社会支持水平与病耻感产生积极影响，同时可降低焦虑与压力水平。本研究结果令人振奋，值得开展进一步的相关研究。
