"Objectives. The objectives are obtain the internal consistency,validity and factorial structure of the Self-Efficacy forAIDS scale, wich was developed in American population byKasen, Vaughan and Walter (1992) and adapted in mexicansamples for López and Padilla (1999). Instruments: It is employedthe Self-efficacy to Prevent the AIDS Scale of 27 itemsof López and Padilla (1999), together with closed questionsLikert type, dicotomics and two opened questions on relevantaspects of the sexual conduct to validate the scale,under a format self-applied test of pencil and paper. Materialand Methods. It is a correlacional study with a notexperimental design of transverse type. It was accomplishedwith a simple random sample of 962 adolescentswich were taken of 60 public health centers of Monterrey.None went to consult by motives related to the AIDS.Results. The scale was adjusted to a normal distribution(Zk-s(Normal)=1.369; p=0.047). It presents a mean of 95.14and a standard deviation of 25.80. Its reliability, by the alphaof Cronbach, was 0.89. SEA - 27 shows a structure of fourindependent factors that explain 58.47% of the total variance.Conclusions: Thus, it is concluded that SEA - 27 is areliable and valid scale.
