Psychometric properties of the Spanish version of the sport motivation scale in Paraguay

The aim of the present research was to validate the Spanish version of the Sport Motivation Scale (SMS) in Paraguay using a sample of 195 athletes, 98 males and 97 females from nine sports. Results of a confirmatory factor analysis partially confirmed the seven-factor structure of the scale. The correlations between the SMS subscales, physical self-concept and goal orientations supported the construct validity of the scale. Likewise, the internal consistency was acceptable in all subscales. Finally, no gender differences were found on any of the subscales. In conclusion, these results support the use of the SMS to assess the motivation in sport context in Paraguay.
