Measures of normal variations in personality, called "psychological type," are frequently used in education (e.g., to identify learning styles) and counseling (e.g., in career counseling). However, the most frequently used measure of types has been criticized on various psychometric grounds. The present study investigated the psychometric properties of an alternative measure, the Personal Preferences Self-Description Questionnaire (PPSDQ). The study was conducted with 328 Hispanic high school students, partly to determine whether the sound psychometric quality of PPSDQ scores was compromised on this sample by vocabulary or language issues. The results of reliability and factor analyses were generally favorable with regard to PPSDQ score integrity. The PPSDQ may have some utility in evaluating Jungian psychological types even with Hispanic American high school students. Appendixes present reliability analyses for the students and for 49 preservice teachers and a correlation matrix for item packets. (Contains 3 tables and 31 references.) (Author/SLD)
