Assessment for symptoms of psychosis
The psychosis is used clinically as a generic term to refer to the positive symptoms of psychotic disorders, namely unusual beliefs and anomalous experiences, as well as disturbances of thought and language. Assessment tools in psychosis reflect these developments in the academic literature, as well as the mushrooming of cognitive behavioural interventions for individuals with distressing psychotic experiences. The Paranoia Checklist was designed to investigate paranoid thoughts of a more clinical nature than the Paranoia Scale, and to provide a multidimensional assessment of paranoid ideation. Thought disorder has not received as much attention as delusions and hallucinations in the research literature, and this is reflected by the smaller number of scales available. Quality of life scales are numerous, but tend to be too lengthy for use with psychotic populations. For hallucinations, a useful place to start is by identifying the physical characteristics of the voices.
