Objective. The present study aims to evaluate the use of LifeGuide to deliver an intervention promoting the performance of three condom-related behaviours in a broad population using persuasive messages. Design. A 3 (intervention: control vs. positively-framed message vs. negatively-framed message) x 3 (time: pre-intervention, post-intervention, three-month follow-up) randomized controlled design was used to compare changes in behaviour and intention. Methods. An online LifeGuide-based intervention was completed by 439 individuals aged between 13 and 85 years of age (females, n = 310, M age = 30.80, SD = 12.75). Pre-intervention, extended Theory of Planned Behaviour (TPB) psychological measures and self-report condom-related behaviour were completed. Immediately post-intervention, TPB measures were completed again. Three months later, all pre-intervention measures were completed. Results. Intention to treat MANOVA analysis showed a main effect of time on the TPB measures (F(36, 400) = 3.92, p =
