Accurate evaluation of patients' psychotic state is essential to decrease psychotic symptoms and protect the patient and others. The aim of this paper is to conduct a literature review in order to access the utility, reliability and validity of current rating scales that are purported to measure psychotic acuity of inpatient population. A search of a number of electronic databases was undertaken to retrieve potential articles that focus on the measurement of acute psychosis. We identified some conceptual and theoretical problems when using a scale that is monitoring the progress of discharge and assesses the outcome of treatments. The findings revealed a difficulty in finding a commonly agreed definition of acute psychosis and a problem of obtaining frequent measures, and the frequency of measurement and fluctuation in psychosis. The most dominant scales in assessing psychosis were reviewed: the Global Assessment of Functioning Scale, the Brief Psychiatric Rating Scale and the Positive and Negative Symptom Scale. Several issues related to the scales' inter‐rater reliability and construct validity remain unexplored. None of these scales addressed the conceptual and theoretical problems that we identified. A new scale that will measure acuity of symptoms in inpatient settings needs to be created.
