Changes in and stability of hostile characteristics: Results from a 4-year longitudinal study of children.

Changes in and stability of hostility characteristics and their relationship to age, sex, and family support were examined among 108 10-18-year-olds in a 4-year longitudinal study. Clinical ratings of Structured Interview potential for hostility, self-reported Minnesota Multiphasic Personality Inventory-derived hostile attitudes, and perceptions of family support were obtained at study entry and at follow-up when subjects were ages 15-21. Results showed relative stability of hostility rankings across 4 years, with males being more hostile than females
