Using structural equation modeling, a good fit was found for a path model with (a) partner communication and intention to use condoms as outcome variables; (b) self-esteem, self-efficacy, and decision making as antecedent variables; and (c) perceived norms about sexual practices, attitudes toward condom use, and knowledge of HIV as mediating variables. A good fit also was found for a slightly elaborated model involving condom use as outcome variable that was fitted in a subsample with 319 adolescents who reported sexual experience. Gender differences are discussed, as well as implications for intervention programs promoting safer-sex behaviors. 收起
