Reliability and validity of the Polish version of the Movement Imagery Questionnaire-3 (MIQ-3)

Abstract

background Imagery is often beneficial not only in gaining a psychological advantage when competing but also in building selfesteem and self-confidence. The aim of this study was to examine the reliability and validity of the Polish adaptation of the Movement Imagery Questionnaire-3 (MIQ-3), consisting of 12 questions measuring 3 dimensions: Visual internal imagery, visual external imagery and kinesthetic imagery. participants and procedure A sample of athletes (N = 276 - 102 women, 174 men (M = 21.25, SD = 6.35)) of various disciplines (football, volleyball, karate, swimming, etc.) with different sport experience (from recreation to the national team) filled in the MIQ-3 questionnaire in the Polish language. results The results of the confirmatory factor analysis (CFA) with maximum likelihood confirmed that the established three-factor model reflects well the relationships observed in the respondents' answers (satisfactory value of RMSEA below the recommended value of.05 (RMSEA =.04) and a high value of the index above.90 CFI (CFI =.93)). Reliability indicators (composite reliability - CR) observed for individual factors indicated a very high internal consistency (external visual imagery =.75, internal visual imagery =.79 and kinesthetic imagery =.82). The results indicated that good stability and internal consistency were maintained over a 3-week period. In addition, analyses were examined across age, level of experience and gender. conclusions The results of the present study support the psychometric properties of the Polish adaptation of the MIQ-3.
