The Music Self-Perception Inventory-Short (MUSPI-S) is a theoretically based instrument consisting of 28 items with subscales that assess music self-concept globally and in six specific areas. The present study sought to validate a German translation of the MUSPI-S using a sample of 444 secondary school students. In addition to participants’ scores from the German translation of the MUSPI-S, associated data included demographic background variables, self-reported school grades in various subjects, and interest in the school subject of music. Confirmatory factor analyses supported the hypothesized factor structure and measurement model for MUSPI-S scores. Latent factor correlations among MUSPI-S subscale scores and correlations of these scores with school grades and interest in the school subject of music aligned well with theoretical expectations and previous research. Findings also provided evidence for strict measurement invariance of scores in the German MUSPI-S across subgroups of gender, school year (i.e., grade level), and musical activity. MUSPI-S subscale factor-level means did not reliably differ among seventh-, eighth-, and ninth-grade students but favored females over males and musically active over non-active students on nearly all subscales. Overall, this evidence supports the use of the German translation of the MUSPI-S in assessing a wide range of important self-perceived musical abilities for research and practical assessment purposes.

对德国 7 至 9 年级学生的音乐自我认知量表 （MUSPI-S） 的简表分数进行验证


音乐自我感知量表-短期 （MUSPI-S） 是一种基于理论的工具，由 28 个项目组成，分量表评估全球和六个特定领域的音乐自我概念。本研究试图使用 444 名中学生的样本来验证 MUSPI-S 的德语翻译。除了参与者从 MUSPI-S 的德文翻译中获得的分数外，相关数据还包括人口统计背景变量、自我报告的学校各种科目的成绩以及对学校音乐科目的兴趣。验证性因子分析支持 MUSPI-S 评分的假设因子结构和测量模型。MUSPI-S 分量表分数之间的潜在因子相关性以及这些分数与学校成绩和对学校音乐科目的兴趣的相关性与理论预期和以前的研究非常吻合。研究结果还为德国 MUSPI-S 在性别、学年（即年级）和音乐活动亚组之间的分数严格测量不变性提供了证据。MUSPI-S 子量表因子水平均值在七年级、八年级和九年级学生之间没有可靠的差异，但在几乎所有子量表上都偏向于女性而不是男性，音乐活跃的学生优于非活跃的学生。总的来说，这些证据支持使用 MUSPI-S 的德文翻译来评估广泛的重要自我感知音乐能力，以用于研究和实践评估目的。
