Interviewer instructions

The purpose of this question is to identify individuals with psychosis such as schizophrenia which is widely recognised as a serious mental problem. Appropriate words should be used in the local language to describe this mental condition that is associated with symptoms that change a person's behaviour, thinking or perceptions.
Behavioural changes are usually noticed by other people, while changes in thinking and perceptions can be identified only by interviewing the individual with the condition. Schizophrenia is often a chronic disease. It may have long periods of
remission between active episodes.
See the explanation for question Q6000 with regard to general aspects of self report for all chronic conditions.
