The aim of the research was to explain the association between early self-schemas and sexual risk behaviours in homosexual men over 25 years of age in the Barcelona-Lechería-Puerto La Cruz conurbation, Anzoátegui State, 2017. The study has been based on the doctrinal approaches of the Bianco School and on the approaches of Applied Behavioural Analysis and Cognitive-Behavioural Orientation. It is a non-experimental design, field research type and correlational level. In order to explore the variables: self-schemas and sexual risk behaviours, we worked with the survey technique, based on a questionnaire, divided into two sections: The self-schema inventory (IA) and the inventory of sexual risk behaviours (ICR), both validated separately by the judgement of three (3) experts in Behavioural Guidance and their reliability was determined using the halving technique, based on the Spearman-Brown reliability coefficient, obtaining significant indices: 0.98 for the IA and 0.71 for the ICR.
