A Validation Study of the Korean-Ruminative Response Scale in Korean Adolescents.

Objective: We aimed to evaluate the psychometric properties of Korean version of Ruminative Response Scale (K-RRS) for Korean adolescents.

Methods: A community sample of 1220 adolescents was recruited from middle schools and high schools. Exploratory factor analyses and confirmatory factor analyses were conducted, and additional analyses were performed to assess the reliability and validity of the K-RRS.

Validation of the mood and anxiety symptom questionnaire in korean adolescents.

Objective: The tripartite model categorizes symptoms of depression and anxiety into three groups: 1) non-specific general distress that is shared between depression and anxiety, 2) depression-specific symptoms that include low positive affect and loss of interest, and 3) anxiety-specific symptoms that include somatic arousal. The Mood and Anxiety Symptoms Questionnaire (MASQ) was developed to measure these three factors of depression and anxiety. The purpose of the present study was to test the psychometric properties of the Korean version of the MASQ (K-MASQ) in adolescents.

Effects of VRK2 (rs2312147) on white matter connectivity in patients with schizophrenia.

Recent genome-wide association studies of schizophrenia reported a novel risk variant, rs2312147 at vaccinia-related kinase 2 gene (VRK2), in multiple Asian and European samples. However, its effect on the brain structure in schizophrenia is little known. We analyzed the brain structure of 36 schizophrenia patients and 18 healthy subjects with regard to rs2312147 genotype groups.

Intolerance of uncertainty, worry, and rumination in major depressive disorder and generalized anxiety disorder.

Intolerance of uncertainty (IU) can be defined as a cognitive bias that affects how a person perceives, interprets, and responds to uncertain situations. Although IU has been reported mainly in literature relating to worry and anxiety symptoms, it may be also important to investigate the relationship between IU, rumination, and depression in a clinical sample. Furthermore, individuals who are intolerant of uncertainty easily experience stress and could cope with stressful situations using repetitive thought such as worry and rumination.

Usefulness of mindfulness-based cognitive therapy for treating insomnia in patients with anxiety disorders: a pilot study.
