Abstract

本研究的主要目的為再度瞭解手側化量表的建構效度,以調查研究與因素分析做為主要的研究與統計方法。研究者以之前所發展的量表以及初步探索性因素分析所獲得的二因素成分為基礎,選取與之前完全不同的小班至小學六年級的學童樣本進行調查。為避免研究偏誤,排除資優與障礙兒童資料後,共獲得644筆資料。研究者首先進行題項分析刪除不適當題項,最後共有20題項進入因素分析歷程,以主成分分析法抽取共同因素並採用斜交轉軸方式後,僅獲得單因素成分,此次結果並不支持之前手側化為二因素的發現。
The purpose of this study was to re-explore the construct validity of a handedness inventory developed by the researchers. Based on the previous study, another psychometric study was conducted again through survey research and factor analysis. Children aged 4 to 12 years from one kindergarten and one primary school in Taipei City were screened for inclusion to the study. None of the subjects in this study had been recruited in the previous study. In order to reduce study bias, suspected gifted children and those with disabilities were excluded. Data obtained from the remaining 644 children were analyzed. The item analysis was conducted and the inappropriate items were deleted. This resulted in an inventory that contained 20 items. Second factor analysis was then carried out using the principle components analysis with directed oblimin rotation. Although we expected two factors' result, the analysis yielded only one factor.
