Nowadays, over two millions people are developing diabetes worldwide and its prevalence is increasing all over the world. Psychological factors have significant impacts on initiation, symptom presentation, and the trend of the disease. Physical treatments may result in non-compliance due to their bothersome effects like pain, especially in children. In addition, restricted diet, meticulous meal, and the amount of activity give rise to non-compliance and exhaustion.

Diabetes is a risk factor for psychiatric disorders such as depression, anxiety, eating disorders, and adjustment disorders in all ages and learning disorders and deficits in visouspatial ability in children and adolescents. Psychiatric disorders lead to more metabolic disregulation, more adverse effects, and decreased quality of life. Psychosocial adverse effects of diabetes are the most important predictors of its mortality.

Psychosocial interventions including medical treatment as well as psychotherapies are effective to reduce morbidities and mortalities of diabetes; patients' qualities of lives are highly correlated to amounts of psychosocial supports. These supports result in better metabolic controls and improving relationship with family members, for children, and better metabolic control and decreased rates of admission in hospital, for adolescence. Psychiatric and psychological interventions lead to patients improving self-confidence, more self-support and better quality of life.
