Abstract Objectives Pelletier, Rocchi, Vallerand, Deci, and Ryan (2013) proposed a new version of the Sport Motivation Scale (SMS; Pelletier, Fortier, Vallerand, Tuson, & Blais, 1995) as a measure of different types of behavioral regulations in sport, as outlined in self-determination theory (Ryan & Deci, 2000). They examined various aspects of reliability and validity of scale scores, and concluded that the new scale performs better than the original version. They also claimed that the SMS-II is superior to other measures of motivation in sport, including the Behavioral Regulation in Sport Questionnaire (BRSQ) developed by Lonsdale, Hodge, and Rose (2008). By comparing the evidence presented in papers by Pelletier et al. and Lonsdale et al., our objective was to examine the relative merits and shortcomings of the two measures and suggest directions for future research into sport motivation measurement.

Conclusion It was not our intention in this paper to dismiss the newly created Sport Motivation Scale II (Pelletier et al., 2013). Instead, our purpose was to examine Pelletier et al.'s (2013) claim that the SMS-II is superior to the BRSQ. We believe the evidence highlights the considerable similarities between the two measures in terms of construct validity evidence derived from both scales, including some evidence that was not entirely consistent with theory. Given these similarities, we question whether the SMS-II is superior to the BRSQ or that it addresses the limitations evident in the BRSQ regarding simplex structure. In our opinion, further work is required for both measures. In the meantime, we suggest that authors carefully examine the reliability and validity of scores derived from the measure they choose for their own studies.
