The purpose of this research was to make a first contribution to the study of possible psychological styles in terms of the way in which athletes approach their sports practice, regardless of the specific sport they practice; allowing the identification of certain persistent and consistent tendencies in their motor and tactical behaviour. To this end, an instrument, the Sport-Practice Style Questionnaire (EPD, for its Spanish initials), was designed and validated, proceeding to determine its construct validity by means of a confirmatory factor analysis (CFA) and a structural equation model (SEM). The sample consisted of 645 participants, 38% male and 62% female, with a mean age of 21 years (20.6 ± 7.6 ± 7.6). The scale has shown good initial results in terms of validity and reliability, giving rise to an unpublished instrument, designed and validated in Spanish, aimed at athletes of different levels, and which allows them to identify different styles in their sporting practice.
