Examined the relations between aggressive problem-solving strategies and aggressive behavior and the intervening role of social acceptance in that relation in early and late adolescents.

The age at which young people expected the initiation of certain sexual practices was studied with 522 15- and 16-year olds. There was progression in modal ages indicated from least intimate to more intimate behaviors.

Using a 1987 sample of 526 undergraduates, this study examines changes in student alcohol use, alcohol abuse, and attitudes toward drinking over their college careers. The maturation of attitude and behavior observed in females was not seen in males, for whom college may represent a period of protracted adolescence. (SLD)

Whether there are themes underlying adolescent drug use, and whether these themes are related to age, sex, or type of drug use was studied with 2,637 6th through 12th graders in Oklahoma. Age, gender, and user differences were identified as reasons adolescents use drugs. (SLD)

Inconsistencies in adolescents' self-reports of sexual behavior were studied for 758 rural adolescents (eighth-grade students in rural Maryland) who completed surveys over 3 years.

Perceptions of costs and benefits are related to gender, age, and the behaviors themselves. (SLD)

Relative fits of 3 factor-structure models of adolescent reckless behavior were examined using the 10-item Reckless Behavior Questionnaire with 1,357 college and 181 high school students. Both one- and two-factor models were found to be satisfactory representations. Implications of a study of construct validity are discussed. (SLD)
