Rating Scale Data and its Utility: Additional Evidence to be Explored in the Medical Education Continuum
Keywords:Construct Validity, Intern Survey, PD Survey, Rating scale
The purposes of this study are to assess the utility of self-appraisals and ratings of program directors (PDs) and to introduce new ways to use self-assessed and rating scale data. The data for this study was collected from graduates of our school who were enrolled in different residency programs around the country. The interns and PDs completed a similar set of questions. The correlation between the ratings of the two group was .21. The Cronbach’s alpha of interns and PD surveys were .89 and .97, respectively. The interns consistently rated themselves lower compared to ratings the PDs assigned them. The two groups agreed on the areas of strengths and weaknesses based on their mean ratings and rank-ordering of competencies. This study proposes that lowest mean ratings of measures that appear at the bottom in the rank-ordering be considered as areas that deserve special attention. The results of this study brought validity evidence to the utility of self-appraisals and PD’s ratings of interns.
