Aggressive Acts Among Patients With Schizophrenia

Status Suspended

Clinical Trial Summary

The purpose of this series of study has a many-fold intention depicted as follows: to describe and characterize schizophrenic patients' aggressive acts in hospital and community, to identify and specify heterogeneity in their structure, and to look for and set up risk factors for prevention. This study investigates four major issues: (1) Establishing an objective behavior rating scale for measuring aggressive acts; (2) Understanding the characteristics and incidence of aggressive acts by patients with schizophrenia; (3) Exploration of the heterogeneous structure of aggressive acts by patients with schizophrenia; and (4) Identifying the risk factors of aggressive acts of patients with schizophrenia.

Clinical Trial Description

Psychiatric patients’ aggressive acts can occur frequently and are recognized as a significant problem in psychiatric services. Understanding of aggressive acts in clinical settings and community is still incomplete and the clinical care of aggressive acts remains unsatisfactory. This study investigates four major issues: (1) Establishing an objective behavior rating scale for measuring aggressive acts; (2) Understanding the characteristics and incidence of aggressive acts by patients with schizophrenia; (3) Exploration of the heterogeneous structure of aggressive acts by patients with schizophrenia; and (4) Identifying the risk factors of aggressive acts of patients with schizophrenia. At first, the content validity, construct validity, and internal consistency of the Chinese version of Violence Scale were examined. Both of retrospective survey and prospective panel design were used for data collection. Patients fulfilling the DSM-IV criteria of schizophrenia in hospital and community, and their siblings and family caregivers, were recruited as different phases of study subjects, after signing informed consent for understanding their past history, prospective occurrence of aggressive acts, and the related risk factors. It is therefore to establish objective measures and to develop insights into the heterogeneity and related risk factors of aggressive acts, for improvement in the management and prevention of aggressive acts. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
