Occupational Therapy Students’ Test/Re-Test Reliability of the Readiness for Interprofessional Education Learning Scale and Interdisciplinary Education Perception Scale
Abstract
The purpose of this study was to establish the test/re-test reliability of two interprofessional education (IPE) instruments, the Readiness for Interprofessional Learning Scale (RIPLS) and the Interdisciplinary Education Perception Scale (IEPS) among occupational therapy (OT) graduate students. The intent was to compare results based on previous IPE experience and year in the program. The RIPLS and IEPS were distributed to 111 OT students at one university. Both instruments were distributed a second time 10-14 days later. Cronbach’s alpha, weighted Kappas, intraclass correlation coefficients (ICC), standard error of measurement, and minimal detectable change were calculated for each instrument. Assessments occurred for all subjects, between students with and without previous IPE experience, and first and second-year students in the program. Overall and between group composite score reliability for the RIPLS and IEPS were fair to excellent (ICC≥0.72). RIPLS subscale ICC’s were variable per previous IPE experience and year in program, ranging from fair-excellent (ICC=0.45-0.93). IEPS subscale ICC’s were excellent for second-year students (ICC≥0.79), and fair-excellent for students with or without previous experience and first-year students (ICC=0.50-0.84). There were no differences for the RIPLS within or between sessions or groups. First-year students had significantly higher scores compared to second-year students within sessions for the IEPS composite score, Competency and Autonomy subscale, and Perception of Actual Cooperation subscale (p≤0.035). Both instruments have acceptable test-re-test reliability; however, previous IPE experience and year in program should be accounted for when distributing the instruments and interpreting the results.
