Validation of the Interprofessional Collaborative Competency Attainment Survey (ICCAS) retrospective pre-test measures.

Establishing the effectiveness of IPE experiences is essential, and current assessment measures may be subject to various types of bias. The Interprofessional Collaborative Competency Attainment Survey (ICCAS) is administered after the learning experience as retrospective pretest and posttest measures of perceived collaborative practice skills. Because the ICCAS does not have an actual pretest, there are potential risks of recall bias and social desirability bias. To address these concerns, Jackson (2017) proposed conducting a true ICCAS pretest before the learning experience and examining the differences between the true and retrospective pretest scores and the differences between these pretest and posttest scores. This study design was implemented for two in-person Interprofessional forums conducted in the Fall ( = 745) and following Spring ( = 599) semesters. Students from 11 (Fall) and 12 (Spring) health professions education programs were included. True ICCAS pretest scores did not significantly differ from the retrospective pretest scores in either sample, although the effect sizes for pretest to posttest gains were slightly smaller for the true pretest scores. These results support and provide confidence for using the standard ICCAS administration methodology by demonstrating the administration methodology is not adversely impacted by recall or social desirability biases.
