In the past, studies examining the effects of stress and social support on glycaemic control have tended to focus on Type I diabetes (insulin dependent) or have employed combined samples. As a consequence, the needs of the Type II diabetes (non-insulin dependent) group have not been fully investigated. This paper examined the role of life stress, support (functional and diabetic) and glycaemic control in a sample of Type I and Type II diabetics. No relationships were found between these factors for the combined group (Type I and Type II) or the Type I and Type II groups assessed individually. When the Type II group was analysed, however, depression and anxiety appeared to be related to HbAl. Furthermore, depressed and anxious subjects were also found to have lower levels of functional support which was associated with poorer levels of glycaemic control. No such relationships were found for the Type I group. This paper discusses these findings and the need for future research to focus specifically on the needs of the Type II group.
