Data from the South Carolina School/Community Program for Sexual Risk
Reduction Among Teens were analyzed to determine direct and indirect e
ffects of demographic and psychosocial factors on female adolescents'
decisions to engage or not engage in premarital sexual intercourse. Th
e Interaction Model of Client Health Behavior provided a framework to
explain the interrelationships among the variables. Age, family struct
ure, peer influence, commitment to partner, and sexual attitudes had d
irect effects on premarital sexual intercourse. Race, religiosity, sex
role attitude, reproductive knowledge, and parent-adolescent communic
ation had indirect effects on premarital sexual intercourse.
