Developmental variations in factors related to initial and increased levels of adolescent drug involvement

The impact of maternal and adolescent factors on initial and increased levels of drug use by adolescents was examined in two groups of adolescents: 210 younger adolescents (ages 12-14 at initial assessment) and 199 older adolescents (ages 15-18). The adolescents and their mothers were interviewed at 2 points in time, 3 years apart. The results indicated that adolescent unconventionality is a crucial determinant fdr both initial and increased levels of drug use for both age groups, but intrapsychic distress is more important for the younger adolescent's initial use. Lack of maternal attachment and poor control techniques were associated with initial levels of drug use for both groups. However, the mother-child relationship and models of the mother's unconventionality had a greater impact on the older than on the younger group's increased involvement. Interactive results suggest that adolescents from both age groups who are well adjusted can off-set the potential risks of maternal models of drug use.
