學齡前兒童動作發展篩檢量表之開發與驗證－初步研究

Abstract

Background: Questionnaires available for screening the motor development of preschool children in Taiwan are few. Therefore, this study developed a Developmental Motor Screening Scale for Preschool Children (DMSSPC), and it exhibits high reliability and validity. Methods: The DMSSPC was developed on the basis of an expert meeting and a literature reviewarticle of assessment tools and questionnaires for screening motor development. After the meeting, subscales of the fine and gross motor scales of the DMSSPC were determined. The fine motor scale comprised grasp, manipulation, and visual motor integration subscales, whereas the gross motor scale contained stationary, locomotion, and body coordination subscales. Data on 150 preschool children (6 months to 6 years old) from Taipei City and New Taipei City were collected, and the children were divided into 6 age groups. All caregivers were interviewed by the rater and completed the DMSSPC at the initial visit. Fifty-four caregivers completed the DMSSPC again within a week. Twenty-four children were subjected to a test involving the Peabody Developmental Motor Scale, 2nd Edition (PDMS-2). The items were revised according to the difficulty estimate and unweighted fitting (mean square error) measured by Rasch analysis. The internal consistency (Cronbach's α) and test-retest reliability (intraclass correlation coefficient [ICC]) were analyzed. For validity, the expert validity and criterion validity of PDMS-2 were analyzed through S-CVI and Pearson correlation coefficients, respectively. The differences in the DMSSPC raw data among the 6 age groups were compared by analysis of variance involving post hoc analysis. Moreover, p ＜ 0.05 was considered significant. Result: After Rasch analysis, 71 and 95 items were included in the fine motor and gross motor scales, respectively. The difficulty estimates for the DMSSPC ranged from -9.77 to 4.52 for the fine motor scale and from -7.90 to 3.79 for the gross motor scale. The DMSSPC exhibited high internal consistency (Cronbach's α ＞ 0.92) and test-retest reliability (ICC = 0.797-0.988, p ＜ 0.01). The fine motor and gross motor scales of the DMSSPC were significantly correlated with all PDMS-2 domains (r = 0.85-0.98, p ＜ 0.01), except for reflex domains. Significant differences were observed in the scores for the various subscales of the gross and fine motor scales among different age groups in children aged younger than 5 years (p ＜ 0.05). The older children had higher motor scores for all subscales, except for the body coordination subscale. Conclusion: The DMSSPC developed in this study exhibited high reliability and validity. Furthermore, significant differences were observed in various motor subscale scores among different age groups. However, the difficulty estimate of all items was simpler. In the future, we will revise the DMSSPC items for adjusting the difficulty estimates.
