Cross-Cultural Adaptation and Validation Study of the Brazilian Version of the Multidimensional State Boredom Scale (MSBS)

Resumen

This study aimed to conduct a transcultural adaptation of the Multidimensional State of Boredom Scale (MSBS) for the Brazilian sociocultural context. A total of 329 volunteers (79% female and 21% male), aged between 12 and 68 years (M = 33.08, SD = 12.44), participated in the study. The process involved expert back-translation carried out by bilingual language professionals and a boredom specialist. Participants completed the MSBS and a socioeconomic questionnaire. A committee of judges evaluated the content validity, indicating excellent levels. Confirmatory factor analysis (CFA) revealed that the scale retained its multidimensional structure, consisting of five factors (Disengagement, High Arousal, Inattention, Low Arousal, and Time Perception subscales), consistent with the original version of the MSBS. Additionally, the Brazilian version of the MSBS demonstrated strong reliability. These findings suggest that the MSBS has excellent psychometric properties in the Brazilian context. The study contributes to a deeper understanding of the state of boredom, its association with mental disorders, and facilitates cross-cultural comparisons within the general population.
