The social-psychological mechanisms that underpin adherence to anti-hypertensive medication are poorly understood. It has been estimated that, within the first year of diagnosis, up to 50% of patients prescribed anti-hypertension agents discontinue their medication, or do not fully adhere to the regimen recommended by their general practitioner (GP). The purpose of this research project was to investigate both motivational and volitional influences on medication adherence within one theory-driven framework.

The project included two linked studies. The first was an empirical study, in which a conceptual model of adherence to anti-hypertensive medication was developed, using an expanded version of Ajzen's (1991) 'Theory of Planned Behaviour' (TPB). The second was an intervention study, in which motivational, volitional, and combined motivational-volitional interventions designed to increase adherence, were tested. The TPB results informed the motivational conditions, and Gollwitzer's (1993) concept of implementation intentions, which deals with the problems people encounter in translating goals into action, informed the volitional ones.
