Développement et validation en langue française de l'Échelle de Mesure de l'Efficacité AutoRégulatrice des Affects en Sport (EARAS)

The purpose of this study was to develop and validate the affective self-regulatory efficacy scale (EARAS) in a French sample. The instrument was developed from an adaptation to the sport context of a scale measuring this construct in everyday life (Bandura et al., 1996, 2001, 2003). A series of four complementary studies was carried out with a total sample of 669 students to: (a) develop a preliminary version of EARAS (study 1), (b) confirm the factorial structure of the instrument and examine its invariance (study 2), (c) evaluate the stability of the instrument (study 3), and (d) examine the construct validity of the scale (study 4). The bifactor model of affective self-regulatory efficacy provided the best fit. The EARAS presents satisfactory psychometric properties and constitutes a reliable and valid instrument for developing future research on the role of affective self-regulatory efficacy with in the sports activities of French people.
