Didactic interventions have shown to improve metabolic outcomes, although benefits last less than six months and are not sustained in the long term. Educational programs need to target psychological factors such as patient's confidence, to ensure self-management strategies are sustained in the long term. Barriers in diabetes self-management behaviours map on to the Information-Motivation-Behavioural skills (IMB) Model of behavioural change. The model was critically constructed based on analysing previous interventions and addressing limitations of the theories that have been used among clients with HIV risk. Chang et al (2014) systematically reviewed the IMB model-based behavioural interventions and found that effects of IMB model persisted up to 12 months in studies followed up patients for 12 months.
