Abstract : The overall goal of this study is to investigate the validity and reliability of factors that contribute to adolescents' sexual risk-taking behaviour. Given the significant contribution of sexual risk-taking behaviour research targeting adolescence in Malaysia and the lack of clear conclusions regarding the impact, this study focuses on assisting and guiding parents at home, teachers in school, and government policymakers in developing competitive strategies in the current challenging years ahead. A total of 123 participants were chosen. Participants ranged in age from 20 to 24 years old and could be either male or female. The questionnaires were distributed to the participants using a random sampling method. The Rosenberg Self-Esteem Scale, General Self-Efficacy Scale, Family Communication Scale, and HIV Risk-Taking Behaviour Scale were administered to the participants. Exploratory factor analysis was used to analyse the quantitative data. The current study's findings indicated that all of the instruments used in this study had good internal consistency and could be used in future studies. Finally, the current scale can be used to identify high-risk adolescents in other states by providing education and conducting the necessary analyses and adaptations.
