1.0 INTRODUCTION


This essay compares and contrasts psychological and biological explanations of major depression, the predominant theories used in explaining major depression. Biological theories of major depression refer to genetic and neurochemical level factors used to explain the aetiology of depression while psychological theories of depression look at cognitive and behavioural-level explanations behind clinical depression (Davey 2011). The essay will look at each theory individually before making comparisons in terms of similarities and later contrast them looking at variances, before coming to a conclusion regarding which one offers the best explanation for major depression.

2.0 What is major depression?

This is a clinical disorder characterised by extreme distress to the person, leading to significant diminishment in many areas of life such as occupational effectiveness or social impairment in relating with other people. Persons who are diagnosed with major depression experience long-term maladaptive cognitive patterns lasting beyond 6 months at which point it becomes major depression (Davey 2011). It is characterized by certain physiognomies such as feelings of sadness, apathy, lack of motivation, loss of appetite, irregular sleeping, and general negativity about self or the world (Weissman et al., 1996).
