Basic psychological needs (BPN) are a central construct of the self-determination theory (SDT). However, there is a lack of instruments specifically adapted to measuring these in the field of music. The aim of this study was to validate a Spanish-language scale of satisfaction and dissatisfaction of BPN in musical activity. The participants were 339 musicians aged 18–65 years old. Internal consistency and convergent and discriminant validity were evaluated by comparing five models using confirmatory factor analysis and a multi-trait multi-method approach. The construct validity was evaluated with respect to satisfaction/fun experienced when performing music. The results indicated a good fit of the model in relation to the measure of each BPN. Satisfaction of the BPN positively predicted satisfaction/fun in performing and practicing music and dissatisfaction produced the opposite effect. The adapted instrument contributes to research on motivation in music education.

音乐活动的基本心理需求量表：测量音乐活动中的基本心理需求

基本心理需求 (BPN) 是自决理论 (SDT) 的核心构造。然而，在音乐领域缺乏专门用于测量这些的仪器。本研究的目的是验证西班牙语言对 BPN 在音乐活动中的满意和不满意量表。参与者是 339 名年龄在 18-65 岁之间的音乐家。通过使用验证性因素分析和多特征多方法方法比较五个模型来评估内部一致性以及收敛和区分有效性。结构效度是根据演奏音乐时体验到的满意度/乐趣来评估的。结果表明模型与每个 BPN 的测量值有很好的拟合。BPN 的满意度正向预测演奏和练习音乐的满意度/乐趣，而不满意度则产生相反的效果。改编的乐器有助于研究音乐教育的动机。
