Pittsburgh engineering attitudes scale — Revised: Evidence for an improved instrument

In the current study, we present data from the administration of our third and final version of the PEAS-R instrument as well as a final set of items. We administered the scale to 980 engineering students in conjunction with established measures of student motivation and strategic learning. An item analysis and a principle axis analysis with an oblimin rotation indicated student responses to the items were internally reliable and structurally valid. A confirmatory factor analysis, a more rigorous test of structural validity, also produced useful results. Finally, a correlational analysis between parceled items from the revised scale and established motivational measures provided evidence of concurrent validity.
