| Abstract: | Analyzed test–retest reliability data gathered from 106 sources (89 independent samples), using a multiple-regression method in an attempt to estimate the effects of several factors on questionnaire stability. We examined 8 self-report inventories: the High School Personality Questionnaire, the 16PF, the MMPI, the Myers–Briggs Type Indicator, the CPI, the Guilford–Zimmerman Temperament Survey, the EPPS, and the OPI. Samples ranged in size and encompassed a wide range of Ss divergent on status and age. We found S's age and status, number of test items, test interitem correlation, and test–retest interval to be significant predictors of reliability. Variables representing general adjustment were found to be less predictable than extraversion variables, and short-term reliability was more predictable than long-term reliability. S's sex and specific questionnaires were not found to have a significant effect on reliability. (PsycINFO Database Record (c) 2010 APA, all rights reserved) |
