What causes mood disorders and what might explain the western world's rising incidence or depression among youth and young adults?
The biological perspective on depression focuses on genetic predispositions and on the abnormalities in brain structures and functions (including those found in neurotransmitter systems). The social-cognitive perspective examines the influence of cyclic self-defeating beliefs, learned helplessness, negative attributions and stressful experiences. The bio-psychosocial approach considers influences interacting on many levels. Increased rates of depression among young westerners may be due to the rise of individualism and the decline of commitment to the religion and family, but this is a correlational finding, so the cause-effect relationship is not yet clear.
