The structural validity and latent profile characteristics of the Abbreviated Profile of Mood States among Chinese athletes
Abstract
Abstract Background This study examines the structural validity of the Chinese version of the Abbreviated Profile of Mood States (POMS) among Chinese athletes and analyzes potential profiles to provide evidence for its effective use and recommendations for its application. Methods A total of 340 Chinese athletes completed the Chinese version of the Abbreviated POMS. Initially, exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were conducted to identify and verify the extractable dimensions of the Abbreviated POMS. Subsequently, the fit of the six-factor and seven-factor models of POMS was tested directly based on their theoretical structures. Finally, latent profile analysis was used to examine profiles based on the four-factor model derived from the factor analysis, six-factor model, and seven-factor model. Results The Abbreviated POMS was refined to a four-factor model, consisting of 27 items across four factors: positive mood, anger, fatigue, and confusion. The hypothesized six-factor and seven-factor models did not demonstrate satisfactory fit, suggesting that the seven dimensions function better as independent subscales. Iceberg and inverse iceberg profiles were observed across the four-factor model, six-factor model, and seven-factor model. Conclusion The Abbreviated POMS does not support its initial hypothesized structure among Chinese athletes. Caution is advised when using the Abbreviated POMS with athletes; it is recommended to use the four-factor model or evaluate each emotion as an independent subscale. The iceberg and inverse iceberg profiles can be used to categorize athletes’ emotional characteristics.
