Abstract

The purpose of this study was to determine Psychometric aspects of the Persian version of Infant Movement Motivation Questionnaire (IMMQ) for infants of 3 to 11 months. In this regard, 528 parents and their infants (239 girls and 289 boys) in Tehran were selected as samples through the method of random cluster sampling. For this purpose, first by using a translation - re translation method, IMMQ was translated into Persian by 3 motor behavior experts and 2 English teaching specialists. Confirmatory and Exploratory factor analysis was used for the validation of questionnaire structure; Cronbach alpha coefficient was computed for internal consistency of questionnaire. Also, intra-class correlation coefficient under test-retest method was used to evaluate the temporal reliability of items. The results of Confirmatory and Exploratory factor analysis showed that IMMQ is multifactorial; so that, in total, four factors consisting activity, exploration, motivation and adaptability can explain % 53/32 of the total variance. Moreover, the fit indexes of the extracted model (PGFI = 0.71, NFI = 0.92, RMSEA = 0.078) were favorable and acceptable. Also, Cronbach alpha coefficient (α = 0/93) and intra-class correlation coefficient (r = 0.88) of the Persian version of IMMQ with 27 questions the like of original version, had acceptable internal consistency and temporal reliability. So the results showed that the Persian version of IMMQ can be used for clinical or research purposes as well as an educational tool for parents.
