To assess the discriminative capacity of the Kenny Music Performance Anxiety Inventory (K-MPAI), in its version adapted for Brazil, in a sample of 230 Brazilian adult musicians.
The Social Phobia Inventory (SPIN) was used to assess the presence of social anxiety indicators, adopting it as the gold standard. The Mann-Whitney U test and the receiver operating characteristic (ROC) curve were used for statistical analysis, with p ≤ 0.05 set as the significance level.
Subjects with social anxiety indicators exhibited higher mean total K-MPAI scores, as well as higher individual scores on 62% of its items. The area under the ROC curve was 0.734 (p = 0.001), and considered appropriate. Within the possible cutoff scores presented, the score -15 had the best balance of sensitivity and specificity values. However, the score -7 had greater specificity and accuracy.
The K-MPAI showed appropriate discriminant validity, with a marked association between music performance anxiety and social anxiety. The cutoff scores presented in the study have both clinical and research value, allowing screening for music performance anxiety and identification of possible cases.
在230名巴西成年音乐家样本中,评估巴西版肯尼音乐表演焦虑量表(K-MPAI)的区分能力。
采用社交恐惧症量表(SPIN)评估社交焦虑指标的存在情况,并将其作为金标准。采用曼-惠特尼U检验和受试者工作特征(ROC)曲线进行统计分析,将p≤0.05设定为显著性水平。
有社交焦虑指标的受试者K-MPAI总分均值较高,且其62%的项目单项得分也较高。ROC曲线下面积为0.734(p = 0.001),认为是合适的。在所呈现的可能的临界分数中,分数-15的敏感性和特异性值平衡最佳。然而,分数-7具有更高的特异性和准确性。
K-MPAI显示出适当的区分效度,音乐表演焦虑与社交焦虑之间存在显著关联。研究中呈现的临界分数具有临床和研究价值,可用于筛查音乐表演焦虑并识别可能的病例。
