Factor validity and reliability of the resistive self-regulatory efficacy in sport scale (RSRESS) in a French sample.
Résumé
The purpose of this study was to develop and validate the Resistive Self-Regulatory Efficacy in Sport Scale (RSRESS) in a French sample. The instrument was developed on the basis of the literature. A series of four complementary studies was carried out with a total sample of 1306 athletes. In the first study, a preliminary version was developed and its clarity was evaluated. The initial factorial analysis identified a one-factor model with good internal consistency. The second study confirmed the factorial structure of the instrument and showed its partial invariance across genders. The third study demonstrated the temporal stability of the RSRESS. In the fourth study, the expected relationships between the RSRESS and both moral disengagement and affective self-regulatory efficacy were found, supporting the construct validity of the instrument. The RSRESS thus presents satisfactory psychometric properties and constitutes a reliable and valid instrument for developing future research on the role of self-regulatory efficacy in moral issues.
