The aim is to examine whether adopting or increasing condom use can be influenced by psychological treatment targeting both motivational and volitional aspects, when these components are matched to the characteristics of the recipients. Method: In a randomized controlled trial, 159 heterosexual young men (intervention groups, n = 113; control condition, n = 46) were exposed to 2 computer-delivered intervention arms, 1 targeting nonintenders (n = 36; motivational intervention arm) and the other targeting intenders (n = 77; volitional intervention arm). Intention and condom use were assessed through self-report questions at 3 points in time, each 2 weeks apart. Motivational intervention involved screen content requesting decisional balance for condom use and focus on past success to trigger self-efficacy. Volitional intervention encouraged the formation of specific if-then plans, where participants were required to choose and write about the most favourable situations by means of reflection on when, where, and how to carry them out, and of thinking about strategies for obstacles that might hinder condom use. Results: Experimental nonintenders obtained higher levels of condom use intention two weeks and one month later and of reported condom use one month later than control nonintenders. Experimental intenders reported an increase in condom use in comparison with control intenders one month later. Conclusions: At a 30-day follow-up, treatment was shown to have helped nonintenders to first increase their condom use intentions and later condom use, and intenders to improve condom use behavior. A stage-based computer-delivered intervention design including motivational and volitional treatment appears to be suitable for improving condom use motivation as well as behavior after a 1-month period.
