Differentiation of Aggressive Behavior of Institutionalized Schizophrenics with the Hand Test

Changes and trends in personality assessment documented through examination of the first issues of the Journal of Personality Assessment (JPA) for the years 1937 to 1997 revealed the following: (a) compared to the Journal of Personality and PsychologicalReview, JPA published more women first authors and coauthors in every issue except in 1987; (b) of the total 8,524 individuals whose assessment protocols comprised data sets in the 7 issues, l,6 15 (19%) were patients and 4,839 (57%) were undergraduate college students; (c) combining patients and nonpatients, the average age of children under 13 was 12.24 years, the average age of high school students was 15.28 years, and the average age of adults was 24.20 years; (d) only 6% of the participants were identified as African American, Mexican American, Asian Americans, or other; and (e) in the 74 articles examined, 98 different tests, techniques, or tasks to assess personality were discussed. We suggest that future research should include a more diverse group of participants that includes more older people and more people of color.
