This study examined violence in dating relationships among Thai secondary school students.Eight schools were selected using a stratified random sampling. Participants were 309 male and 326 female students ranging in ages from 14 to 19. Self-administered questionnaires were used to collect data in 2003. Overall, 19% of males and 6% of females reported experiences of the physically and psychologically abusive relationship. Gender played a significant role in perceptions of sex role-stereotypes, dating experiences, and experiences of dating violence. Threatening to end a relationship was the main sexual coercive act used to obtain sexual intercourse.
