Abstract
Diabetes Mellitus identified as the world’s fastest growing chronic disease is also capable of serious life threatening complications such as heart disease, visual impairment, kidney disease, limp amputation, and stroke. Diabetes and depression have consistently been found in many studies to exist co-morbidly. Given its association with poorer self-care adherence and decreased glycemic control, depression increases the risk of complications associated with diabetes. On the other hand, social support and self-efficacy are associated with better self-care adherence as it is argued that they are protective factors in the development of depression in chronic disease populations. In order to significantly reduce the risks of diabetic related complications, adherence to self-management of the disease is vital. This study aimed to firstly investigate whether the psychosocial factors of depression, social support, and self-efficacy predicted adherence to specific type 2 diabetes self-care behaviours such as blood glucose monitoring, physical activity, and medication compliance. Secondly, this study aimed to assess how each of these psychosocial measures affect diabetes self-care adherence tasks by investigating the moderating effect of depression and social support in the relationship between self-efficacy and the three chosen diabetic self-care tasks. It was hypothesised that depression would predict poor diabetes self-care adherence, while social support and self-efficacy should predict good diabetes self-care adherence. It was also hypothesised that social support and depression would moderate the relationship between self-efficacy and the three diabetes self-care adherence tasks. Specifically, self-efficacy may have a greater effect on diabetes self-care adherence tasks when combined with social support, and have a lesser effect on diabetes selfcare adherence tasks when combined with depression. The participants in this study consisted of a clinical population of consumers who were registered in the Linking Chronic Disease Services Program and identified as having a complex or poorly managed chronic disease. The measure used in this study is developed by the Linking Chronic Disease Service which has included the Ongoing Needs Identification tool as a major part of their assessment. This study is secondary to a larger program evaluation that evaluates the success of the Linking Chronic Disease Services Program. De-identified archival data collected for the program evaluation were manipulated to use for research purposes required in this study. Results found only partial support for self-efficacy in its prediction of diabetes self-care adherence tasks, significantly predicting only medication compliance to the exclusion of blood glucose monitoring and physical activity. Considering that the data were not measured and collected for research purposes, results were largely non-significant and inconclusive. Based on the inconclusive results of this study, it is highly recommended that future research with this clinical population use measures that are recognised and designed specifically for research purposes to assess variables under consideration.
