“…In response to the proposed objective, the instrument's psychometric properties were examined in a sample of pre-service teachers. In accordance with the results of previous research (Barkoukis et al, 2008;Guay, Morin, Litalien, Valois, & Vallerand, 2015;Núñez et al, 2010;Stover et al, 2012), the confirmatory factorial analysis, conducted to provide evidence of validity based on internal structure, considered the factor correlated model originally proposed by Vallerand et al (1989), as well as, different alternative models that could be supported by the SDT postulates. Furthermore, the instrument's invariance across gender, its internal consistency and temporal stability were analysed.…”
