Innovation self-efficacy: A very brief measure for engineering students

Abstract

When survey time is limited, education researchers may be faced with the choice of using an extremely brief measure of innovativeness or using no measure at all. To meet the need for a very brief measure, a 5-item innovation self-efficacy (ISE.5) scale was developed using the 19-item Dyer et al. Innovative Behavior Scale (IBS) as a starting point, adapted for undergraduate engineering students, and then condensed using confirmatory factor analysis. The ISE.5 measures innovation self-efficacy as a unitary construct drawn from Dyer et al.'s five innovative behavior components (Questioning, Observing, Experimenting, Networking Ideas and Associational Thinking) and has good internal and external validity as well as good test-retest reliability. The ISE.5 (as a measure of innovation self-efficacy) is shown to be an important mediator between innovation interests and a desire to pursue innovative work as a career postgraduation. This mediator relationship is consistent among important sub-populations of engineering students such as females, underrepresented minorities and first generation college students. While not a substitute for a full multi-factor innovation assessment tool, the ISE.5 can serve as an important indicator of innovation self-efficacy among an undergraduate engineering student population.
