Schizophrenia is considered to be the most costly, severe, chronic and devastating psychiatric illness that presents the most challenging mental health problem (Andreasen, 1989; Carson, 1996). Considered the leading public health problem, the lifetime prevalence rate is high at approximately 1% of the population; the occurring rate is one in 4000 diagnosed per year with severe morbidity and significant mortality rates linked to a high numbers of suicides (Andreasen & Carpenter, 1993; Silverstein et al., 2006). Bleuler's unique concept, that the defining features of schizophrenia are the splitting of diverse psychic functions and disintegrating of the personality, saw the true improvement of an absolute mental health disorder, that had precise necessary negative symptoms (ambivalence, autism, affective blunting, & attentional impairment) and negative accessory symptoms (psychotic based hallucinations, delusions, bizarre behaviour and formal thought disorder) that are psychogenically determined (Andreasen & Carpenter, 1993; Bruijnzeel & Tandon, 2011). Bleuler is said to have significantly broadened the scope of the schizophrenia diagnosis as a disease entity, with the idea that mild to severe cases exist and thus, the presence of simple and latent terms further branded a group of schizophrenias (Andreasen & Carpenter, 1993; Bruijnzeel & Tandon, 2011). For the purpose of this essay, I would be discussing the clinical cycle through the Assessment, Formulation, Intervention and Evaluation of the disorder talked about above.
Assessments.
In the assessment segment of the clinical cycle, it involves using suitable evaluations of assessment, which recognizes the concentration of symptoms and are related to the specific model of intervention that may be necessary. According to the DSM-V (APA, 2013), diagnostic criteria for schizophrenia involves; Criteria A: Two (or more) of the following, each present for a significant portion of time during a 1 -month period (or less if successfully treated).
