OBJECTIVE: Type 2 diabetes mellitus and its complications are increasingly prevalent in Sri Lanka. Patients with poor glycaemic control commonly experience diabetes complications. Although diabetes self-management is a vibrant feature in management of diabetes, studies on the effect of health education on patient clinical health outcomes are inadequate in Sri Lankan perspectives. The is study aimed to evaluate the impact of health education on patient clinical outcomes, utilising a translated version (Sinhala) of health education impact questionnaire (heiQ™) in patients diagnosed with type 2 diabetes for their health-related behaviours, capabilities and motivations.

DESIGN: This study was designed as a prospective, non-experimental, step-up controlled study, with health education as the main intervention.

SETTING: The study sample recruited from two main independent tertiary care facilities in Western and Southern Provinces of Sri Lanka.

METHODS: Patients who were diagnosed with Type 2 diabetes and comply with the selection criteria were enrolled to the study. The intervention consisted with two repeated one to one education sessions followed up in six and twelve months with further subdivision of intervention group to sub groups (A and B) followed up with single and repeated education intervention. The education session was delivered to sub group B at baseline and after six months and at baseline for cases subgroup A. The heiQ™ was administered at baseline prior to any intervention or measurement of study parameters (HbA1C, BP, Lipids and weight) and repeated at six and 12 months.

RESULTS: The results of this study based on analysis of covariance (ANCOVA) indicated significant improvement of the knowledge in all other domains between baseline to six months, six to twelve months and baseline to twelve months except for skills and technique acquisition between baseline to six months among intervention group in comparison to the non- intervention group (control group). The assessment of health education program an average score of more than five confirming the success of the education intervention.

CONCLUSION: The translated version of heiQ™ was well adapted in Sri Lanka for assessing knowledge improvement among Sri Lankan participants with type 2 diabetes.
