Psychometric properties of the Brunel Mood Scale among athletes and non-athletes in Singapore

Researchers in sport and exercise psychology have shown an enduring interest in mood responses, the study of which relies on well-validated and culturally relevant measures. The current study was a cross-cultural validation of the 24-item Brunel Mood Scale (BRUMS: Terry et al., [1999]. Development and validation of a mood measure for adolescents. Journal of Sports Sciences, 17, 861-872. doi:10.1080/026404199365425) in a Singaporean context. The six-factor measurement model was tested among a sample of 1,444 English-speaking Singaporean participants (440 females) aged from 18-65 years, including 954 who were involved in sport. Structural equation modelling showed a good fit of the measurement model to the data (CFI = .956, TLI = .950, RMSEA = .052). Multisample analyses supported the invariance of the measurement model in different subsamples based on gender, age group, and sport participation. Concurrent measures correlated with subscale scores in line with theoretical predictions. Internal consistency and test-retest reliability were acceptable. Mood responses varied predictably by gender, age group, and sport participation. Findings supported the psychometric integrity of the BRUMS, providing opportunities to examine the antecedents, correlates, and behavioural consequences of mood responses among Singaporeans.
