"External validation of the Runco Ideational Behavior Scale"
MetadataShow full item record
The Runco Ideational Behavior Scale, RIBS, was recently created as a tool for assessing ideation. It is intended as a useful criterion for measuring divergent thinking, which includes originality, fluency, and flexibility. While studies have shown that the RIBS has internal consistency, there is no evidene for how it relates to other measures of creativity. This study compared the RIBS to two other creativity tests, How Do You Think (HYDT)and the Torrance Figural Test of Creative Thinking (TTCT) to examine convergent validity. Each test was given to 72 students at a private midwestern university. The students were either introductory psychology students or advanced painting students, 46 were female and 26 were male. There was no statistically significant relationship between the RIBS and the TTCT, showing no convergent validity between the two tests which claim to measure the same construct. Contrary to expectations, there was large significant correlation between the HDYT and the RIBS. These results suggest that the RIBS and the TTCT do not measure the same construct. The strong positive correlation between RIBS and HDYT scores suggests the RIBS measures constructs similar to those of the HDYT. This brings into question the usefulness of the RIBS as a measurement of divergent thinking.
