with mental health professionals has also been found to help people with diabetes develop the skills to manage their medications and challenges of self-management effectively. Psychological mechanisms and adherence As self-management of diabetes typically involves lifestyle modifications, adherence may pose a significant self-management burden on many individuals. For example, individuals with diabetes may find themselves faced with the need to self-monitor their blood glucose levels, adhere to healthier diets and maintain exercise regimens regularly in order to maintain metabolic control and reduce the risk of developing cardiovascular problems. Barriers to adherence have been associated with key psychological mechanisms: knowledge of self-management, beliefs about the efficacy of treatment and self-efficacy/perceived control. Such mechanisms are inter-related, as one's thoughts (e.g. one's perception of diabetes, or one's appraisal of how helpful self-management is) is likely to relate to one's emotions (e.g. motivation to change), which in turn, affects one's self-efficacy (one's confidence in their ability to engage in a behaviour to achieve a desired outcome). As diabetes management is affected by an individual's emotional and cognitive state, there has been evidence suggesting the self-management of diabetes is negatively affected by diabetes-related distress and depression. There is growing evidence that there is higher levels of clinical depression in patients with diabetes compared to the non-diabetic population. Depression in individuals with diabetes has been found to be associated with poorer self-management of symptoms. This suggests that it may be important to target mood in treatment. In the case of children and young people, especially if they are socially disadvantaged, research suggests that it is important that healthcare providers listen to and discuss their feelings and life situation to help them engage with diabetes services and self-management. To this end, treatment programs such as the Cognitive Behavioural Therapy - Adherence and Depression program (CBT-AD) have been developed to target the psychological mechanisms underpinning adherence. By working on increasing motivation and challenging maladaptive illness perceptions, programs such as CBT-AD aim to enhance self-efficacy and improve diabetes-related distress and one's overall quality of life. Research Type 1 diabetes Diabetes type 1 is caused by the destruction of enough beta cells to produce symptoms; these cells, which are found in the Islets of Langerhans in the pancreas, produce and secrete insulin, the single hormone responsible for allowing glucose to enter from the blood into cells (in addition to the hormone amylin, another hormone required for glucose homeostasis). Hence, the
