想像力量表之編製

Abstract

本研究目的在發展「想像力量表」，視其信度與效度，全量表共包含13題開放式題項。研究者透過項目分析、Cronbach’s α、重測信度、個別項目信度、成分信度、組合信度及驗證性因素分析等統計方法來分析處理實證資料。根據驗證性因素分析結果顯示，實證資料尚且支持Vygotsky之想像力概念理論（Vygotsky’s theoretical conceptions of imagination）暨想像力激發機制（the arousing mechanism of imagination）之「想像力量表」的假設模式，兩者適配尚稱符合。本研究初步發現「想像力量表」可分為「發想力」、「流暢力」、「變通力」，以及「獨創力」四個分量表，而四個分量表分數表徵之一級潛在因素，可以被「想像力量表」解釋的百分比分別為 .46、 .96、 .55、 .20。

This study develops and examines the reliability and validity of an imagination scale (IS) with 13 open-ended items categorized into 4 subscales: initiation, fluency, flexibility, and originality. Item analysis and confirmatory factor analysis were used to determine Cronbach's α, test-retest reliability, individual item reliability, composite reliability, and criterion-related validity of the IS. Second-order confirmatory factor analysis shows that there was an acceptable goodness-of-fit among the IS, Vygotsky’s theoretical conceptions of imagination, and the arousing mechanism of imagination. The IS accounted for .46, .96, .55, and .02 of the variance associated with the 4 subscales.
