Cultural adaptation and validation of the Sport Imagery Questionnaire for Children (SIQ-C) to the portuguese language

Abstract

The aim of this study was to translate, adapt and validate the Sport Imagery Questionnaire for Children to Brazilian Portuguese. For this purpose, analyzes of reproducibility, internal consistency and confirmatory factor analysis were conducted. The final sample consisted of 521 athletes from 14 sports and ages 14 and 19 (M = 16.31, SD = 1.18). High indices of internal consistency (α = 0.870), reproducibility (0.824) and content validity were verified. In the confirmatory factor analysis, it was observed the appropriate global indexes of adjustment to the five-factor instrument model (RMSEA = 0.060; CFI = 0.90; TLI = 0.88; SRMR = 0.047). The translated instrument has adequate psychometric indicators to evaluate sport imagery, presents a reproducible factor structure and is a reliable test to measure the frequency of imagery use in Brazilian adolescent athletes
