摘要：background Imagery is often beneficial not only in gaining a psychological advantage when competing but also in building self_esteem 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),consist?ing 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,vol?leyball,karate,swimming,etc.) with different sport expe?rience (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 estab?lished 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,inter?nal 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 ex?perience and gender.conclusions The results of the present study support the psychometric properties of the Polish adaptation of the MIQ-3.
