Czech adaptation of the Brunel Mood States for adolescent athletes

Abstract

The Brunel Mood States is a 24-items long questionnaire (formerly referred to as the Profile of Mood States for Adolescents POMS-A) used to capture emotional profile of an individual. It has been used in various settings including sport psychology, where it is considered a valid indicator for overtraining syndrome. The aim of this study was to develop the Czech adaptation of BRUMS and verify its psychometric properties in adolescent athletes. The data were collected from a sample of 246 participant (50.8% females; age range 14-19 years). Confirmatory factor analysis was used to evaluate original six-dimensional structure (with factors of Depression, Tension, Confusion, Anger, Fatigue, and Vigor). Even though this model showed acceptable fit to the data, Depression and Tension factors were empirically indistinguishable. Therefore, we proposed and verified alternative five-factor model with these two factors collapsed. Measurement invariance across gender was assessed using the Multiple Indicators Multiple Causes (MIMIC) model. Although three items showed signs of differential item functioning, the Czech adaptation of the instrument can in general be considered a measurement invariant.
