Music Performance Anxiety, a subset of social anxiety disorder (SAD), can significantly impede the lives of professional voice users (PVUs). This pilot cohort study evaluates the efficacy of Transformational Breath (TBr), a facilitated conscious breathing technique that employs high ventilation breathing, as a therapeutic intervention for anxiety management in PVUs. We recruited PVUs diagnosed with mild to moderate SAD and randomly assigned them to an intervention group (n = 12) that completed three TBr sessions with a certified practitioner, or to a waitlist control group (n = 12). Both groups were assessed using a battery of psychological (Generalised Anxiety Disorder Scale (GAD-7), Patient Health Questionnaire (PHQ-9), Social Phobia Index (SPIN), Kenny’s Music Performance Anxiety Inventory (K-MPAI), Warwick-Edinburgh Mental Well-Being Scale (WEMWBS)) and physiological (blood pressure, heart rate, respiratory rate, oxygen saturations, peak expiratory flow rate) measures on three separate occasions. The outcome measures were evaluated before and after each session in the intervention group. No Group x Time interaction was found for any of the physiological or psychological measures. However, a significant Time main effect was found for K-MPAI (X2(5)=20.157, p = .001) and GAD-7 (X2(5)=12.79, p = .025) within the TBr group. Post hoc Wilcoxon-signed rank tests with Bonferroni correction for multiple comparisons revealed significant differences between K-MPAI scores at time points Post 3 and Pre 3 (z = 3.00, adj. p = .040), Post 3 and Pre 2 (z = 3.27, adj. p = .016) and Post 3 and Pre 1 (z = 2.95, adj. p = .048). No pairwise differences were found for GAD-7. The pattern of results suggests that TBr may be effective in acutely decreasing music performance anxiety.

音乐表演焦虑（Music Performance Anxiety）属于社交焦虑障碍（Social Anxiety Disorder, SAD）的一个亚型，可对专业嗓音使用者（Professional Voice Users, PVUs）的生活造成显著阻碍。本先导队列研究评估了转化性呼吸疗法（Transformational Breath, TBr）——一种由认证从业者引导、采用高通气量呼吸模式的有意识呼吸技术——用于管理专业嗓音使用者焦虑症状的治疗效果。本研究招募了确诊为轻度至中度社交焦虑障碍的专业嗓音使用者，并将其随机分配至干预组（n=12）与等待列表对照组（n=12）：干预组需在认证从业者的指导下完成三次转化性呼吸疗法疗程，对照组则纳入等待名单。两组均在三个独立时间点接受多维度评估，其中心理评估量表包括广泛性焦虑障碍量表（Generalised Anxiety Disorder Scale, GAD-7）、患者健康问卷（Patient Health Questionnaire, PHQ-9）、社交恐惧指数（Social Phobia Index, SPIN）、肯尼音乐表演焦虑量表（Kenny’s Music Performance Anxiety Inventory, K-MPAI）以及沃里克-爱丁堡心理健康量表（Warwick-Edinburgh Mental Well-Being Scale, WEMWBS），生理评估指标则涵盖血压、心率、呼吸频率、血氧饱和度与峰值呼气流速。干预组在每次疗程前后均接受结局指标评估。分析结果显示，所有生理与心理指标均未出现组间×时间的交互效应。但在转化性呼吸疗法组内，K-MPAI（χ²(5)=20.157, p=0.001）与GAD-7（χ²(5)=12.79, p=0.025）均存在显著的时间主效应。经Bonferroni多重比较校正的事后Wilcoxon符号秩检验显示，K-MPAI得分在以下时间点间存在显著差异：疗程3后与疗程3前（z=3.00, 校正p=0.040）、疗程3后与疗程2前（z=3.27, 校正p=0.016）以及疗程3后与疗程1前（z=2.95, 校正p=0.048）；而GAD-7得分未发现显著的两两差异。整体结果模式表明，转化性呼吸疗法或可快速降低音乐表演焦虑水平。
