The items are based on the 42 core competency statements developed by the Interprofessional Education Collaborative's expert panel (2011). This Collaborative convened representatives from six national professional associations: the American Association of Colleges of Nursing, the American Association of Colleges of Osteopathic Medicine, the Association of Schools of Public Health, the American Association of Colleges of Pharmacy, the American Dental Education Association, and the Association of American Medical Colleges.
Overall response rates were low, with 481 of 3236 students responding (14.9%) for the original study. Response rates in subsequent samples ranged from 9% to 19%.
In the original study, factor analysis accounted for 79% of the variance in the response data in four factors. Component alphas for the four factors ranged from 0.96 to 0.98. In the refinement studies, exploratory factor analysis with another sample showed alphas for two strong factors consistently in the same range. Confirmatory factor analysis with a third sample yielded a normed Chi-square (X2/df) value of 2.85, which is within the acceptable range for model fit with high alpha values for each factor (0.92 for Factor 1 and 0.96 for Factor 2).
Relation to Other Variables:
Scores on the four domains in the original study did not significantly differ across years of education or discipline (i.e., medicine, nursing, and pharmacy). However, the median score for roles and responsibilities was significantly different for nurses compared to other disciplines.
