Aggression in African-American boys: a discriminant analysis.

The main purposes of this study were to determine whether familial variables found to be related to the development of aggressive behavior in Caucasian boys may also be related to similar aggressive patterns in inner-city African-American boys and to assess the relative importance of these variables for classifying the subject population into aggressive and nonaggressive groups. Discriminant analyses were performed using 83 African-American boys, with a mean age of 13.9 years, who were classified as institutionalized aggressive, noninstitutionalized aggressive, and noninstitutionalized nonaggressive subjects. Although the same father and mother variables were used in the analyses, the father variables were not related to group membership. Furthermore, the results showed that both groups of aggressive boys reported more aggression within as well as outside their family home settings than their nonaggressive counterparts. Socioeconomic-related factors such as employment status of parent(s), size of family, and number of parents in the household were not useful predictors of aggressive and nonaggressive group membership.
