The aim of this study was to evaluate theprevalence of night eating syndrome (NES) and its correlates in schizophrenicoutpatients. Methods: The 14 items of self-reported night eatingquestionnaire (NEQ) was administered to 201 schizophrenic patients in psychiatricoutpatient clinic. We examined demographic and clinical characteristics, bodymass index (BMI), subjective measures of mood, sleep, binge eating, andweightrelated quality of life using Beck's Depression Inventory (BDI),Pittsburgh Sleep Quality Index (PSQI), Binge Eating Scale (BES) and Koreanversion of Obesity-Related Quality of Life Scale (KOQoL), respectively. Results: The prevalence of night eaters in schizophrenicoutpatients was 10.4% (21 of 201). Comparisons between NES group and non-NES grouprevealed no significant differences in sociodemographic characteristics,clinical status and BMI. Compared to non-NES, patients with NES reportedsignificantly greater depressed mood and sleep disturbance, more binge eatingpattern, and decreased weight-related quality of life. While 'morning anorexia'and 'delayed morning meal' (2 of 5 NES core components in NEQ) were notdiffered between groups, 'nocturnal ingestions', 'evening hyperphagia', and'mood/sleep' were more impaired in NES group. Conclusion: These findings are the first to describe theprevalence and its correlates of night eaters in schizophrenic outpatients.These results suggest that NES has negative mental health implications,although it was not associated with obesity. Further study to generalize theseresults is required.

Background Although mood stabilizers such as lithium (LIT), valproate (VAL), and lamotrigine (LMT) appear to be efficacious treatments for bipolar disorder (BD) in research settings, the longterm response to these mood stabilizers in clinical practice is highly variable among individuals. Thus, the present study examined the characteristics associated with good or insufficient responses to long-term treatment with LIT, VAL, or LMT for BD. Methods This study retrospectively analyzed the medical records of patients who visited an outpatient clinic with a diagnosis of BD I or II. Data from patients who were treated with one of three mood stabilizing medications (LIT, VAL, or LMT) for more than 6 months were selected, and the long-term treatment responses were evaluated using the Alda scale. For the purposes of this study, two response categories were formed: insufficient response (ISR), including non-response or poor response (Alda total score � 6), and good response (GR; Alda total score � 7). Results Of the 645 patients included in the present study, 172 were prescribed LIT, 320 were prescribed VAL, and 153 were prescribed LMT for at least 6 months. A binary logistic

ObjectiveThis study aimed to evaluate the validity and reliability of a Korean version of the Mood Disorder Questionnaire-Adolescent version (K-MDQ-A) as a screening instrument for bipolar disorders in adolescents.MethodsOne hundred two adolescents with bipolar disorders and their parents were recruited from November 2014 to November 2016 at 7 training hospitals. One hundred six controls were recruited from each middle school in two cities of South Korea. The parent version of the original MDQ-A was translated into Korean. The parents of all participants completed the K-MDQ-A. The diagnoses of bipolar disorders were determined based on the Korean version of K-SADS-PL. The test-retest reliability with a 10-month interval was investigated in 33 bipolar adolescents.ResultsK-MDQ-A yielded a sensitivity of 0.90 and a specificity of 0.92 when using a cut-off score of endorsement of 5 items, indicating that symptoms occurred in the same time period and caused moderate or serious problems. The internal consistency of the K-MDQ-A was good. The correlations between each item and the total score ranged from 0.40 to 0.76 and were all statistically significant. Factor analysis revealed 3 factors that explained 61.25% of the total variance. The mean total score was significantly higher in bipolar adolescents (7.29) than in controls (1.32). The Pearson correlation coefficient for the total test-retest score was 0.59 (p<0.001).ConclusionThe K-MDQ-A completed by parents showed the excellent validity and reliability and may be a useful screening tool for adolescents with bipolar disorders attending in- and outpatient psychiatric clinics.

Background: The aim of this study was to screen Korean college students for correlates, and comorbidities associated with attention-deficit hyperactivity disorder (ADHD). Methods: A total of 2,593 college students participated in the study. Socio-demographic and clinical data were collected and self-report scales, such as the Adult ADHD Self-Report Scale-Version 1.1, the Center for Epidemiologic Studies Depression Scale, the Korean version of the Mood Disorder, a modified Korean version of the 16-item Prodromal Questionnaire, and the Alcohol Use Disorders Identification Test were included. Students with and without ADHD were compared using univariable analyses, and the association of ADHD with other psychiatric comorbidities was predicted using multivariable analyses. Results: Of the total participants, 4.7% were diagnosed with ADHD. Multivariable analysis revealed that ADHD in college students was significantly associated with depression, psychotic-like experience, alcohol abuse, and female sex after adjustment. We found that ADHD in young college students was associated with several psychiatric comorbidities. Conclusion: These results suggest the need for early detection of ADHD in young adults and highlight the importance of implementing early psychiatric intervention for problems such as depression, psychotic-like experience, and alcohol abuse in adults with ADHD.
