Validity of the Korean Version of the Brief Irritability Test in Psychiatric Patients.

Objective: This study aimed to investigate the validity and reliability of the Korean version of the Brief Irritability Test (BITe) and adapt it for Korean patients with psychiatric disorders.

Methods: A total of 296 patients at the Department of Psychiatry of Hanyang University Guri Hospital completed the BITe, Korean Beck Depression Inventory-II, Korean Beck Anxiety Inventory, the Korean version of the State-Trait Anger Expression Inventory, and Barratt Impulsiveness Scale-11. Construct validity was confirmed through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA).

A psychometric evaluation of the National Stressful Events Survey for PTSD-Short Scale (NSESSS-PTSD) among Korean psychiatric outpatients.

The National Stressful Events Survey for PTSD-Short Scale (NSESSS-PTSD) is a brief screening measure for DSM-5 PTSD that has not been evaluated for its psychometric properties in clinical population. We developed a Korean version of the original English scale through translation-back translation process and examined its reliability and validity among treatment-seeking adults at a psychiatric outpatient unit of a university-affiliated hospital in South Korea. The sample comprised adults diagnosed with PTSD ( = 100) and other psychiatric disorders ( = 134).

The Relationship between Stress, Inflammation, and Depression.

A narrative review about the relationship between stress, inflammation, and depression is made as follows: Chronic stress leads to various stress-related diseases such as depression. Although most human diseases are related to stress exposure, the common pathways between stress and pathophysiological processes of different disorders are still debatable. Chronic inflammation is a crucial component of chronic diseases, including depression.

Dissociative Identity Disorders in Korea: Two Recent Cases.

Although dissociative identity disorder (DID), the most severe of the dissociative disorders, has retained its own diagnostic entity since its introduction in the DSM-III, cases of DID are rarely seen in South and East Asia, likely due to the higher prevalence of possession disorder. We report two patients with DID who were recently admitted to our inpatient psychiatric unit and demonstrated distinct transitions to several identities. Their diagnoses were confirmed through a structured interview for dissociative disorders and possible differential diagnoses were ruled out by psychological, neuroimaging, and laboratory tests.
