Reliability and Validity of the Dissociative Experiences Scale Among South Korean Patients With Schizophrenia.

The Dissociative Experiences Scale (DES) is the most widely used self-report tool for use with the general population and various clinical entities, including those with schizophrenia. This preliminary study tested the reliability of the DES, especially temporal stability and validity, in patients diagnosed with schizophrenia receiving inpatient or outpatient treatment. The DES was administered at a university-affiliated training hospital in South Korea to a total of 68 patients (39 inpatients and 29 outpatients) whose diagnosis of schizophrenia was confirmed using the Structured Clinical Interview for DSM-IV Axis Disorders.

Print media coverage of post-traumatic stress disorder: content analysis of three major Korean newspapers.

The print media is still one of major sources for health-related information. To shed light on how the media accurately delivers information for post-traumatic stress disorder (PTSD), we searched the newspaper articles and analyzed their contents for accuracy in the description of symptoms, causes, and treatment of PTSD. The articles featuring PSTD were searched from the very first available to 2010 at on-line search systems of three major Korean newspapers.

Psychometric properties of the Childhood Trauma Questionnaire-Short Form (CTQ-SF) in Korean patients with schizophrenia.

Objective: Despite increasing interest in the relationship between childhood trauma and psychosis, measures used to assess early trauma have not had their psychometric properties extensively tested among individuals with serious mental illness. This study investigated the reliability and validity of one of the most widely-used self-reports of early adversity, the Childhood Trauma Questionnaire, Short Form (CTQ), among patients with schizophrenia.

Methods: The CTQ was administered to 100 patients (52 inpatients and 48 outpatients) diagnosed with schizophrenia in three training hospitals.

However, few studies have investigated the chronological change of such delusions within a society. To investigate specifically the changes in the persecutory delusions of schizophrenia that have occurred over time, we compared the nature of the persecutors and their persecutory behaviors among inpatients with schizophrenia.
