Test-retest Reliability of the Persian version of the questionnaire Affordances in the Home Environment for Motor Development-Infant Scale and its Relation with Infant Movement
Since the home environment is the first place on which children (particularly, those under two years of experience and development) are highly dependent, the existence of a questionnaire for evaluating this environment is necessary. Therefore, in the present study, the test-retest reliability of the Affordance in the Home Environment for Motor Development-Infant Scale (AHEMD-IS) is reported.
The aim to this study was to investigate certain psychometric characteristics of the AHEMD-IS. Therefore, 112 mother-infant (3–18 months old infants) couples participated in this study. The AHEMD and the Ages and Stages Questionnaire (ASQ) were completed by all the participants and 46 participants re-completed the questionnaire for investigating their repeatability. Finally, the collected data were analyzed using tests of correlation coefficients in SPSS-21.
The findings of the AHEMD-IS enjoys acceptable reliability. The intra-class coefficient (ICC) of the total score of the questionnaire was 0.78, the intra-class coefficient of physical space was 0.96, the intra-class coefficient of a variety of stimuli was 0.93, the intra-class coefficient of the gross motor toys was 0.93, and the intra-class coefficient for fine motor toys was 0.96. In addition, the concurrent validity indicated that the section on the diversity of stimuli and toys for fine movements had a significant correlation with the motor sections of the ASQ (p
The results of this study indicated that the AHEMD-IS is a reliable instrument for 3–18 month old infants.
