Development of a multi-component lifestyle intervention for preventing type 2 diabetes and cardiovascular risk factors in adults with intellectual disabilities.

Background We report on the development of the 'STOP Diabetes' education programme, a multi-component lifestyle behaviour change intervention for the prevention of type 2 diabetes and cardiovascular risk factors in adults with intellectual disabilities (ID). Methods We combined qualitative stakeholder interviews with evidence reviews to develop the intervention, guided by the MRC Framework and informed by intervention mapping and two existing diabetes prevention programmes. We conducted two pilot cycles drawing on additional stakeholder interviews to inform and refine the intervention. Results The STOP Diabetes education programme employed a theoretical framework, using sound learning and behavioural principles and concrete kinaesthetic methods, to provide the grounding for innovative games and activities to promote health behaviour change in adults with ID. Qualitative data also suggested that two educators and one support person delivering a programme of one carer session followed by seven 2.5-h sessions over 7 weeks was acceptable to service users, carers and educators and appeared to benefit the participants. Conclusions The STOP Diabetes education programme was successfully developed and is suitable for a definitive randomized controlled trial.
