Dispositional insight scale: Development and validation of a tool that measures propensity toward insight in problem solving

This article reports the development of a brief self-report measure of dispositional insight problem solving, the Dispositional Insight Scale (DIS). From a representative Australian database, 1,069 adults (536 women and 533 men) completed an online questionnaire. An exploratory and confirmatory factor analysis revealed a 5-item scale, with all items loading onto a single factor. Internal consistency was acceptable with a Cronbach’s alpha of .74. The DIS showed convergent validity with other constructs that are theoretically related to insight: High need for cognition, intuition and positive affect. Normative data for the scale are also reported. The DIS appears to be useful for measuring a disposition toward insight in problem-solving.
