This paper discusses mobile-based interventions for management of non-communicable diseases such as hypertension and Type 2 diabetes. It builds upon the Persuasive System Design (PSD) model for developing mobile-based multi-intervention services for the prevention and management of the above- mentioned diseases, especially in developing countries such as Bangladesh. Identified gaps include lack of studies on system framework or design component for behaviour change services; no studies on smartphone based multi-intervention services for behaviour change; no user acceptance studies on smartphone services for management. This paper uses (a) Hevner's model for identifying gaps in the existing literature and developing a framework to address some of the gaps (b) the PSD model and social cognitive theory for developing the framework and content for behaviour change service to manage hypertension and Type 2 diabetes respectively. This paper has potential design implications for a broader research in mobile-based PSD and multi-intervention service for future developments.
