The objective of this paper is to understand the intended sexual and condom behaviour patterns among teenage higher secondary school students in India. To achieve this, variables including perceived norms, perceived peer group norms, risk behaviour patterns, perceived chances of getting AIDS and relevant sociodemographic variables were regressed on intended sexual behaviour. Regression of actual sexual behaviour was carried out with perceived norms, perceived peer group norms and intended sexual behaviour as the independent variables. In this paper a conceptual model has been framed based on the theory of reasoned action, health belief model and self-efficacy theory. Cumulative scores are computed for perceived norms, perceived peer group norms, risk behaviour patterns, opinion on handling condoms and perceived chances of getting AIDS. Along with these variables, possible confounding variables such as age, gender, type of family, mother's education and father's education were considered for their effect on intended sexual and condom behaviour. The results revealed that perceived norms and perceived peer group norms showed significant association with intended sexual behaviour and actual sexual behaviour and that children of more highly educated parents are less likely to engage in sexual activities in their adolescent years.
