Adaptation and validation into Spanish of the brief scale of mood regulation through music (B-MMR)

BACKGROUND: Music plays a crucial role in mood regulation by influencing emotions, reducing stress, and enhancing overall well-being. Few instruments measure the use of music as a mood regulatory strategy. This study aimed to adapt and validate the Brief Music in Mood Regulation Scale (B-MMR), a 21-item self-report instrument, to the Spanish language. METHOD: Data was analysed from 429 Spanish students and was collected between September and December 2024. The B-MMR was used alongside the Basic Emotions Questionnaire. A confirmatory factor analysis, reliability, invariance analysis and external validity tests were conducted. RESULTS: Confirmatory factor analysis of the B-MMR with 7 factors and 3-item each demonstrated robust indicators of global adjustment replicating the original structure of the questionnaire, as well as satisfactory reliability and validity data. The invariance analysis showed homogeneity in the measurement model. CONCLUSIONS: The Spanish version of the B-MMR is a valuable instrument to further understand music's psychological impact on mood in the Spanish population.
