Relationship between Competency to Consent to Treatment and Psychological Well-Being: Mediating Effect of Empowerment and Emotion.

This study was conducted to evaluate the competency to consent to the treatment of psychiatric outpatients and to confirm the role of empowerment and emotional variables in the relationship between competency to consent to treatment and psychological well-being. The study participants consisted of 191 psychiatric outpatients who voluntarily consented to the study among psychiatric outpatients. As a result of competency to consent to treatment evaluation, the score of the psychiatric outpatient's consent to treatment was higher than the cut-off point for both the overall and sub-factors, confirming that they were overall good.

Development of a Modified Korean Version of the Epworth Sleepiness Scale Reflecting Korean Sociocultural Lifestyle.

Objective: The Epworth Sleepiness Scale is a measure used for the diagnosis of sleep disorders including obstructive sleep apnea (OSA) syndrome, insomnia, and narcolepsy. Although a Korean version has been developed (the KESS), Korean lifestyle such as the floor culture and low driving rates has not been considered. We aim to develop and validate a modified KESS (mKESS) that reflects the Korean lifestyle.

Circadian polymorphisms in night owls, in bipolars, and in non-24-hour sleep cycles.

People called night owls habitually have late bedtimes and late times of arising, sometimes suffering a heritable circadian disturbance called delayed sleep phase syndrome (DSPS). Those with DSPS, those with more severe progressively-late non-24-hour sleep-wake cycles, and those with bipolar disorder may share genetic tendencies for slowed or delayed circadian cycles. We searched for polymorphisms associated with DSPS in a case-control study of DSPS research participants and a separate study of Sleep Center patients undergoing polysomnography.

Evaluation of two circadian rhythm questionnaires for screening for the delayed sleep phase disorder.

Objective: Delayed sleep phase disorder (DSPD) is a condition in which patients often fall asleep some hours after midnight and have difficulty waking up in the morning. Circadian chronotype questionnaires such as Horne-Östberg Morningness-Eveningness Questionnaire (MEQ) and Basic Language Morningness (BALM) scale have been used for screening for DSPD. This study was to evaluate these two chronotype questionnaires for screening of DSPD.

Development and validation of a screening scale for depression in Korea: the Lee and Rhee Depression Scale.

Objective: The aim of this study was to develop a culturally sensitive instrument that addressed how individuals express and experience depression to detect this disorder in Koreans. We also assessed the validity, reliability, and diagnostic utility of this scale (Lee and Rhee Depression Scale; LRDS).

Methods: The sample consisted of 3,697 normal adults selected from 12 administrative districts (Do) and 448 Korean patients diagnosed with depression using the Structured Clinical Interview for DSM-IV Axis I disorders (SCID-I).

Coercion in psychiatric care: can paternalism justify coercion?

Background: It has long been debated whether coercion can be justified as paternalism in the field of mental health and it is still a continuing issue of controversy today.

Aims: This study analyses whether coercive intervention in mental health can be justified by the basic assumptions of paternalists: the assumption of incompetence, the assumption of dangerousness and the assumption of impairment.

Method: This study involved 248 patients: 158 (63.

No Evidence for Association between Tyrosine Hydroxylase Gene Val81Met Polymorphism and Susceptibility to Tardive Dyskinesia in Schizophrenia.

Objective: Tyrosine hydroxylase (TH) is the rate-limiting enzyme in dopamine biosynthesis. Because the TH Val81Met polymorphism is located in the amino-terminal regulatory domain of the tetrameric enzyme, it is a candidate marker for susceptibility to dopamine-related traits. We investigated the hypothesis that TH Val81Met polymorphism can influence susceptibility to tardive dyskinesia (TD) in schizophrenia.

Association study between glutathione S-transferase GST-M1, GST-T1, and GST-P1 polymorphisms and tardive dyskinesia.

Objectives: Data from several studies suggest that oxidative stress may play a role in the pathophysiology of tardive dyskinesia (TD). Glutathione S-transferase (GST) enzymes play important roles in protecting cells against oxidative stress. In the present study, we investigated the hypothesis that polymorphisms in genes for these detoxifying enzymes can influence susceptibility to TD in patients with schizophrenia.
