| Study objectives | To test whether: implementation intention strategies increase three-month compliance to prescribed medicines among patients in primary care compared to those control group patients using their usual strategies. Do implementation intentions increase adherence to medication prescribed for coronary heart disease? N.B. The pilot study revealed problems with recruiting non-adherent participants. Two alternative studies were, therefore, administered. |

| Intervention | Both studies were randomly controlled trials: Study 1: 120 cardiac patients were recruited and randomised into three groups (control, Theory of Planned Behaviour (TPB) questionnaire only, TPB questionnaire + formed implementation intention). They were telephoned at 7, 28 and 90 days post-recruitment. Fruit and vegetable consumption was recorded at recruitment and at each of the follow-up time points. 97 participants completed the study. Study 2: 249 patients presenting with a prescription for antibiotics were recruited and randomised into four groups (control, TPB questionnaire only, TPB questionnaire + formed own implementation intention, TPB questionnaire + researcher provided implementation intention). They were telephoned on the day after their antibiotics were due to be completed to record their adherence to the medication. A fifth group of participants was recruited who only received the follow-up telephone call. 241participants completed the study. |
