- Abstract
The results of a psychometric study of the Test of Patient Knowledge are reported. The 50-item, multiple-choice test, developed by Etzwiler and associates at the International Diabetes Center, consists of a total score and seven subscores based on seven nonoverlapping content categories: nutrition, insulin, general knowledge, methods of control, pattern control, exercise, and complications. The results described herein provide evidence for the validity of the test (content, concurrent, and discriminant validity), a high level of reliability (Cronbach's alpha = .88), readability for the layperson at the 7th- to 8th-grade level, and sensitivity to instructional gains. The literature on psychometric research with other tests of patient knowledge of diabetes is reviewed and compared with the results of this study.
