The aim of this study was to investigate the validation of the Persian version of the Sports Mental Exercise Questionnaire.
The method of this study is a non-experimental research and is one of the instruments of validation research in which the required information was collected cross-sectionally. The statistical population consisted of athletes from East Tehran. The sample also included 400 people who were randomly selected and completed a sports mental exercise questionnaire. The questionnaire consists of 20 questions, two main dimensions (mental skills and mental techniques) and 5 subscales including basic skills, functional skills, interpersonal skills, self-talk and mental training. To assess the validity of the factor constructs, a confirmatory factor analysis was conducted on the basis of structural equation modeling. The Cronbach's alpha coefficient was used to determine internal consistency and the intraclass correlation coefficient was used to determine temporal reliability (at two-week intervals).
  The results show a good fit of the Persian version of the Mental Exercise Questionnaire. Internal consistency and temporal stability were also acceptable.
Thus, the Persian version of Sports Mental Exercise Questionnaire has acceptable validity among athletes and psychologists and researchers can use this questionnaire.
