This paper presents the investigation of the psychometric properties of the Graduate Program Self-Assessment (GPSA) questionnaires, developed by the Educational Testing Service, for the evaluation of nursing doctoral education. The data are from the 1984 cooperative program evaluation from 326 faculty, 659 doctoral students, and 296 alumni. The primary emphasis was on assessing content validity, factorial (construct) validity, concurrent (criterion-related) validity, and internal-consistency reliability (coefficient alpha) of the 16 summary scales for the faculty, student, and alumni questionnaires. In general, the questionnaires demonstrated satisfactory validity and reliability. The analysis provided supportive evidence that there are indeed multiple dimensions of quality in doctoral education and that those dimensions can be measured with the GPSA questionnaires and demonstrated to correlate with other measures of quality. Specific recommendations for summary scale changes were made to improve the psychometric properties of the scales. Fifteen tables are provided. (Author/TJH)
