STABILITY OF EDWARDS PERSONAL PREFERENCE SCHEDULE NEED SCALE SCORES AND PROFILES OVER A SEVEN-WEEK INTERVAL

Abstract

Seven-week test-retest correlations were obtained for need scale scores and individual need profiles for a sample of pre-flight students. The coefficients for need scales were in the 50's and 60's (2 of 15 were below .50). Mean scores on 7 of the need scales changed significantly over the seven-week intertest interval. Of the 74 individual profile correlations, 64 were significant; the median value was .75. There was some evidence that low profile stability was related to a low consistency score on one or both administrations. The test-retest data were compared with other reliability studies of the Personal Preference Schedule.
