Exploring patient perceptions of movement through the stages of change model within a diabetes tele-care intervention.

Achieving strict control of diabetes is challenging for many patients and most need regularly to depend on ongoing support from health care professionals. One approach that might successfully provide this in a cost-effective and acceptable way is the delivery of advice and support over the telephone (tele-care). To date the process and effects of tele-care have however rarely been studied. This article explores the potential of one behavioural model, the trans-theoretical stages of change model (TTM), to understand and theorize about behaviour change for this chronic disease. Case study data are drawn from a wider randomized controlled trial (RCT) set up to assess the effectiveness of a pro-active call centre-based stepped treatment support to people with type 2 diabetes. The case study demonstrates the relevance and importance of the TTM model in this area. Different experiential and behavioural processes were of particular significance and held different meanings for the various change groups.
