Abstract
The widely accepted bipartite definition of creativity, including originality and usefulness is often operationalized as such to evaluate divergent thinking (DT) tasks. Based on prior research, showing that these two subdimensions interact with each other to constitute creativity, the (face) validity of their operational separation for measurement was questioned. Another issue to be tackled was the workload that stems from scoring ideas (resulting from DT tasks) individually and twice. To examine methods decreasing workload, the common procedure was compared to the snapshot scoring technique. Furthermore, to investigate possible effects of another operational dimension definition on face validity, a combined ‘original usefulness’ dimension was proposed and compared to the separate dimension approach. Behavioral science university students (N = 198) took part in an online experiment (survey) with a 2x2 factorial design. They either rated ideas or idea sets (snapshot scoring) and either according to the separate dimensions or the combined ‘original usefulness’ dimension. The combined dimension approach showed greater outcome-related face validity reinforcing prior findings on the interaction effect of the two subdimensions and opposing their independent operationalization. Individual idea scoring was perceived as more accurate as compared to the snapshot scoring and interrater-reliabilities strengthened this stance. However, measuring outcome-related face validity reinforced the promising nature of the snapshot scoring technique. Taken together, future research should further explore the potential of the snapshot scoring technique and ways to increase inter-rater reliability when utilizing a combined dimension approach. Keywords: creativity measurement, divergent thinking tasks, snapshot scoring technique, operational definition, face validity, workload, interrater reliability
