This study was conducted to evaluate whether the adjectival self-description checklist may provide a viable method of quickly obtaining initial personality type information. The Personal Preferences Self-Description Questionnaire (PPDSQ) was administered to more than 420 college students, and data were analyzed using classical reliability analysis and both exploratory and LISREL confirmatory factor analyses. Students also took the Myers Briggs Type Indicator (MBTI). Results generally supported a conclusion that PPSDQ scores are reasonably reliable and valid. Thirteen tables and two figures present details of the statistical analyses. An appendix presents some descriptive MBTI statistics. (Contains 21 references.) (Author/SLD)
