Measurement model of subjective mood states in adolescent athletes

Abstract:

This study was designed to obtain evidence of the internal validity of a Spanish version for adolescents of the Profile of Mood States questionnaire, POMS (Andrade, Arce, Armental, Rodriguez and De Francisco, 2008). Andrade et al.'s version was previously developed with items selected through scaling objects. The sample for this study was composed of 320 adolescent athletes - 194 males and 126 females - with a mean age of 14.95 (SD = 1.29). A confirmatory factor analysis was used to test the congruence between the data and the proposed model. The best fitting measurement model was one with 29 items and 6 first-order factors: Tension, Depression, Anger, Vigour, Fatigue and Friendliness. The values obtained for the most habitual global goodness-of-fit indices were as follows: χ2(361) = 684.25 (p <.01), CFI =.96, NNFI =.96, RMSEA =.053 (with limits of.047 and.059 for the confidence interval at 90%) and SRMR =.061.
