More humane explanation, disorder has physical cause- no blame attached. Cause recognised as being outside patient’s control, i.e. genetics. Effective treatments; treatments successful, drug therapy- widely used to treat a range of common psychopathologies. Based on medical model, psychological evidence, well established scientific principles form basis. Support for foundations on which the research and subsequent claims are made. Classification system based on medical model, symptoms, provide diagnosis/treatment, good level of reliability. 2 doctors follow same outline, same symptoms, should give same diagnosis to patient.
Rosenhan’s study questioned reliability- ‘normal’ patients classified as insane by several psychiatrists. Questions the reliability/validity of systems which biological model is based. Complex mental illnesses are biological in origin- reductionist; reducing complex human behaviour to one single cause, exclusion of all others. Explaining in terms of biology removes responsibility from individual, result in ‘giving up’ on overcoming their conditions. Only treat symptoms of disorder, prevent underlying causes being dealt with. Result in relapse or increased dependency. Labelling; ethical concern in relation to the ‘label’ a mental illness diagnosis can have on an individual and the social stigma that this may entail for them in different areas of their life.
