This study investigated the relationship of terminal core values to delinqu
ency, substance use, and sexual behavior in a sample of 544 high school stu
dents. Students were classified according to their dominant value, and comp
arisons were made in regard to thirty-one indicators of delinquency, substa
nce use, and sexual activity. As predicted by social control and strain the
ories, groups valuing fun/enjoyment and security were strongly identified w
ith delinquency and substance use. Groups valuing self-respect, being well-
respected, sense of accomplishment, warm relationships with others, and sen
se of belonging exhibited low frequency of delinquent behavior and substanc
e use. Sense of belonging tended to be related to lower sexual activity, wh
ile warm relationships with others and being well-respected were associated
with the most sexual activity. Gender differences in problem behaviors wer
e also explored. The implications for theory and intervention are discussed
, and values self-confrontation is proposed as a method for reducing proble
m behaviors.
