Issues surrounding the classification and diagnosis of schizophrenia, including reliability and validity
Reliability concerning schizophrenia is the extent to which psychiatrists can agree on the same diagnosis when assessing the patients independently. The document which psychiatrist use is call DSM 4r, this document is a positive reinforcement as it improved reliability and can eventually lead to curing patients which is the main point of diagnosis. However it also disproves reliability as not all cases of schizophrenia are of the same cause and strength, notably this leads to individual difference, each person who has symptoms of schizophrenia has a different set of psyches. Furthermore Rosenhans study on ‘being sane in insane places ‘clearly displays unreliability of diagnosis. the study involved normal people saying to psychiatrists that they heard voices in their head ‘auditory voices’, all of the normal patients were diagnosed as having schizophrenia, also none of the staff recognised them to be normal. Above all this study makes it clear that diagnosing a patient is more complicated than simply claiming or having one of more symptoms of schizophrenia.
On the other hand validity is a key aspect when diagnosis and classification is going to take place. If scientists cannot agree on who has schizophrenia then questioning what it is becomes completely meaningless.
Another point which is closely linked to validity is subjectivity, each psychiatrist has come from different backgrounds and varies in cultural upbringing so, not all the psychiatrists will agree on every aspect of the diagnosis process, which makes each patient very different and they cannot necessarily follow the same diagnosis program. However the outcome of diagnosis is beneficial, and the main and most important aspect of diagnosis is that its aimed to help people after treatment, and the outcome of the diagnosis and classification links to all aspects of the medical model.
