Psychometric characteristics of the Brunel Mood Scale in a Singaporean context

Mood profiling serves several functions in the sporting domain, including monitoring of athlete mindset, early problem identification, performance prediction, and screening for pathogenic behaviours. The 24-item Brunel Mood Scale (BRUMS; Terry, Lane, Lane, & Keohane, 1999) is yet to be validated or researched extensively in a Singaporean context, and hence the current investigation provided a cross-cultural re-validation of the BRUMS. The six-factor measurement model was tested on a sample of 1,444 English-speaking Singaporean participants (age range = 18– 56+ yr., median = 22–25 yr.; male = 991, female = 440, unspecified = 13), including 954 involved in sport and 490 non-sport participants. In addition, a subgroup of 243 participants completed the BRUMS and concurrent measures of affect and psychological distress. A subgroup of 141 participants completed the BRUMS on two occasions to assess test-retest reliability. Structural equation modelling showed a good fit of the data to the measurement model (CFI = .937, TLI = .927, RMSEA = .062). Multi-sample modelling (sport vs non-sport, ≤ 25 yr. vs 26+ yr.) further supported the factorial validity of the measure. Relationships between BRUMS subscales and concurrent measures were consistent with theoretical predictions. Internal consistency and test-retest reliability coefficients were acceptable. Findings supported the psychometric integrity of the BRUMS for use in a Singaporean context, providing opportunities for further investigation of the antecedents, correlates and behavioural consequences of mood responses among Singaporean sport and non-sport participants
