The aim of this study was to translate into Spanish and validate the Multidimensional Sportspersonship Orientations Scale (MSOS), which was developed in English and validated by Vallerand et al. (1997). The MSOS consistsof five subscales that measure full commitment toward sport, respect for social conventions, respect and concern for rules and officials, respect and concern for opponents, and negative approach towards sportspersonship. The Spanish version of the scale showed acceptable levels of internal consistency and temporal stability over a four-week period. The results of a confirmatory factor analysis confirmed the five-factor structure of the MSOS. Correlations among the subscales confirmed the scales construct validity. Finally, gender differences were obtained. These findings support the use of the Spanish version of the MSOS for assessing individual differences in sportspersonship orientations
