They share many commonalities. Both the diseases have a very high prevalence, mortality, and disability. The current article reviews the available evidence on psycho‑social interventions in management of depression in diabetes. A literature search was performed using MEDLINE, PubMed, PsycINFO, Embase, and Cochrane Review for English language articles published during 1960‑2012. There is limited published literature on role of psycho‑social interventions in management of depression among diabetics. The available evidence suggests that psycho‑social interventions, particularly CBT, are effective in improving depression in patients with diabetes. However, these interventions are not consistently associated with improvement in markers of glycemia control (HbA1c levels). Key words: Cognitive behavioral therapy, collaborative care, depression, diabetes, psycho‑social interventions Introduction in people with diabetes was 11% and the prevalence of clinically relevant depression was 31%. A study conducted Diabetes and depression are major public health problems by World Health Organization across 60 countries found associated with significant burden. They share many health decrement to be greater with co‑morbid depression commonalities. Both diabetes and depression are and diabetes in comparison to either of them present considered as civilization disease, i.e., diseases, which alone.[4] Individuals with diabetes and depression had a increases with the development of the society, due to change 2‑fold increase in health care costs compared with those in the environmental and social factors. Diabetes and who did not have depression.[5] Diabetics with co‑morbid depression also share a bi‑directional causal association.[1] depression had a 36‑38% increased risk for mortality over a 2‑year period.[6] Both the diseases have a very high prevalence, mortality, and disability. When present together, these conditions impact Most cases of depression among diabetics get undetected individuals’ quality of life significantly. The prevalence due to commonality of the symptoms of the two of depression in diabetes ranges between 15‑40% in conditions (fatigue, weight gain or weight loss, appetite multi‑national studies.[2] Anderson et al.[3] in a meta‑analysis changes, and sleep disturbances), associated stigma and negative perception of depression.
