The Development of an Imagination Scale

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.
