The relationship between fine particulate matter (PM) and schizophrenia severity.

Purpose: Although particulate matter (PM) is reported to affect the rate of emergency admissions for schizophrenia, no study has examined the relationship between particulate matter less than 2.5 μm in diameter (PM) and the severity of schizophrenia.

Methods: We obtained data on patients with schizophrenia at a psychiatric hospital, and on air pollution in Sakai, Japan between Feb 1, 2013 and April 30, 2016.

Psychological assessment of acute schizophrenia patients who experienced seclusion either alone or in combination with restraint.

Objective Numerous studies on the effects of seclusion and/or restraint in acute psychiatric treatment have reported both positive and negative effects. However, no studies to date have evaluated the effects of seclusion and/or restraint on schizophrenia patients using a rating scale. Thus, to examine the effects of seclusion and/or restraint on schizophrenia patients, we used the Brief Psychiatric Rating Scale and assessed the psychological condition of patients.
