This study addresses the association of diverse individual variables, traditionally associated with sexual risk practices in the general population, with sex under the influence of alcohol in adolescents with divorced parents. A sample of 132 adolescents provided information about their knowledge and attitudes toward HIV/AIDS and sexual risk behaviors, self-concept, social anxiety, and sexual sensation seeking. Binary logistic regression revealed that not having sex under the influence is associated with a more positive predisposition to practice safe sex when finding an obstacle, and with less sexual sensation seeking. These and other findings are discussed. (Contains 2 tables.)
