其他摘要：Imagery can be defined as the ability to represent and rehearse in the mind behaviors related to a given situation. The Sport Imagery Questionnaire was developed to measure the frequency of imagery use among athletes. The present study aimed to adapt and to evaluate the psychometric properties of the Brazilian version of this instrument. Study 1 appraised content validity using five sport scientists as judges to quantify the quality of the adaptation for each item; then the Content Validity Coefficient was calculated. Study 2 had 260 athletes from six types of sport answer the Brazilian questionnaire. Exploratory and confirmatory factor analyses were conducted to test factorial validity, Cronbach ’ s alpha was calculated to assess reliability, and comparisons between groups were used as criterion validity. Study 1 results showed good quality of the adaptation according to the judges. Study 2 showed a 5-factor latent structure which corroborates with the literatu re. Reliability of the scale was high ( α = .91), whereas separately subscales ranged between Motivational General: Arousal ( α = .87) and Motivational Specific ( α = .94). Regarding group differences, sex showed no significa nt difference between men and women ( p = .55; d = .09) and neither did levels of practice between amateur, semi-professionals and professional athletes ( p = .71; f = .07). Types of sports revealed moderate effect size and significantly less imagery practice among synchronized swimming, football and beach volleyball athletes, whereas mixe d martial artists showed higher frequency of imagery ( p <.05; f = .23). Factor structure, reliability and validity of mixed groups are evidence of a successful cross-cultural adaptation of the Sport Imagery Questionnaire to Brazil.
