Age and Sex Differences in Personality during Adolescence
The study sought to determine what changes occur in adolescent personality in the age period between 12 and 19 yr. Specifically the aims were to identify the personality dimensions that distinguish boys from girls at various age periods and any age trends in personality change. The Interpersonal Style Inventory was administered to 331 boys and 358 girls from six high schools. Boys and girls were significantly differentiated on this inventory at each of four age levels through use of discriminant function analyses. Girls scored more Sociable, Nurturant, Conscientious, Help-seeking, and Anxious at all age levels. The boys scored more Detached, Withholding, Self-sufficient, and Stable. Results were in close agreement with those reported by Sealy and Cattell and by Garai and Gurin. Age trends, however, were few in number.
