[Adaptation and validation of the Spanish version of the Sport Anxiety Scale SAS-2 for young athletes].

The aim of this study is to design a Spanish version of the Sport Anxiety Scale (SAS-2). The questionnaire, originally developed by the Washington University research group in sport psychology to evaluate anxiety in young athletes, was translated and adapted following the APA protocol and its psychometric properties were assessed through internal consistency analysis, confirmatory factor analysis and validity evidence. The Spanish version of the Sport Anxiety Scale has revealed good internal consistency indexes in each subscale and its factor structure has faithfully replicated the one obtained in the original measure. Results indicate that the adapted version of the questionnaire is an adequate and valid measure for the assessment of anxiety in young athletes.
