Under the Ministry of Health and Welfare of the Republic of Korea, the National Autism and Developmental Disorder Centers for people with developmental disabilities are gradually expanding. The headquarters of the National Autism and Developmental Disorder Center provides support for education, training, and research, and several centers have been effectively operating since 2020. This study aimed to provide practical recommendations and guidelines for specialists such as clinical psychologists, child psychiatrists, allied professionals, community workers, and related administrators. It was developed as a guideline to promote early diagnosis, provide important information on integrated treatment, and assist people with developmental disabilities in Korea to make the best decisions for their quality of life.

Background: Self-harm is an important public health problem with increasing incidences among adolescents for over a decade. This study aimed to identify factors associated with self-harm in adolescent psychiatric inpatients in Korea. We also investigated clinical characteristics associated with nonsuicidal self-injury disorder (NSSI-D) and suicidal behavior disorder (SBD) according to the Diagnostic and Statistical Manual of Mental Disorders 5 criteria. Methods: This retrospective study included 215 adolescents aged between 12 to 18 years, who were admitted to the psychiatric ward of Samsung Medical Center, Seoul, Korea, from January 2014 to February 2021. Participants were divided into three groups according to NSSI-D and SBD diagnostic criteria. Collected data were analyzed using chi-square test and analysis of variance test. Results: Overall, 57.7% of the participants (n=124) reported self-harm at least once in their lives. Patients with self-harm were more likely to have experienced parental conflict, parent-child relational problems, and verbal, physical, or sexual abuse. Among the three groups divided according to NSSI-D and SBD diagnostic criteria, patients with both NSSI-D and SBD were more likely to have experienced parent-child relational problems than those with either NSSI-D only or SBD only. Conclusion This study shows that parent-child relational problem is associated with high incidences of selfharm. Especially, the parent-child relational problem seemed to be a risk factor for SBD among patients with NSSI-D. These are important findings that provide an understanding of the self-harm characteristics and therefore improve prevention and treatment strategies in psychiatric adolescent patients.

Objective: This study aimed to determine the tic aggravation event rate and cumulative incidence rate in the use of methylphenidate (MPH) treatment in attention-deficit/hyperactivity disorder (ADHD) and the factors that influence tic aggravation. Methods: We conducted a retrospective chart review of children and adolescents aged between 6 to 15 years, who were diagnosed with ADHD from January 2017 to December 2019. A total of 121 subjects were included. The MPH dosage, psychiatric family history, comorbidity and past history of tics were assessed through chart review and the psychological examinations data were included. Collected data were analyzed using Cox regression and Kaplan-Meier survival analysis. Results: Tic aggravation event rates without a past history of tics were 2.9% with MPH treatment in ADHD. Past history of tics, total MPH dosage and age were the factors associated with tic aggravation ([HR 21.46, p<0.001], [HR 0.94, p=0.023], [HR 0.79, p=0.021] for each). Cumulative incidence of tic aggravation was different between groups with or without past tic history. When treated with MPH, all tic aggravation appeared within approximately eight months but for subjects with a past history of tic, aggravation showed within approximately six months (p<0.001). Conclusion Tic aggravation event rate was significantly low especially in the group without a past history of tics with the use of MPH in ADHD. However, a thorough assessment of past history of tics, and close monitoring during the first six-eight months of treatment with MPH is needed to avert a potential worsening of tics.

Chronic spontaneous urticaria (CSU) is defined as the occurrence of spontaneous wheals, angioedema, or both for >6 weeks in the absence of specific causes. It is a common condition associated with substantial disease burden both for affected individuals and societies in many countries, including Korea. CSU frequently persists for several years and requires high-intensity treatment; therefore, patients experience deteriorations in quality of life and medication-associated complications. During the last decade, there have been major advances in the pharmacological treatment of CSU and there is an outstanding need for evidence-based guidelines that reflect clinical practice in Korea. The guidelines reported here represent a joint initiative of the Korean Academy of Asthma, Allergy and Clinical Immunology and the Korean Dermatological Association, and aim to provide evidence-based guidance for the management of CSU in Korean adults and children. In Part 1, disease definition, guideline scope and development methodology as well as evidence-based recommendations on the use of antihistamines and corticosteroids are summarized.

Objectives: To identify the clinical utility of the Korean version of the Barkley Deficits in Executive Functioning Scale (K-BDEFS) assessing executive functioning. Methods: The patient group included 144 adult attention-deficit/hyperactivity disorder (ADHD) patients visiting the Adult ADHD Outpatient Clinic of the National Center for Mental Health. Adult ADHD Self-Report Scale version 1.1, Mini International Neuropsychiatric Interview, and K-BDEFS were used. The control subjects were 144 age, sex, and education-matched general adults who participated in the study of the validity of the K-BDEFS in Samsung Medical Center. Results: An analysis of the mean total K-BDEFS score, executive functioning symptom count, and ADHD-executive function (EF) index score revealed a significant difference between the adult ADHD and control group (p<0.05). Five subscales of the K-BDEFS, which assess the specific domains of the executive function, revealed a significant difference between the ADHD group and control group (p<0.05). The area under curve (AUC) of the K-BDEFS total score, the EF symptom count, and the ADHD-EF index were 0.943, 0.949, and 0.908, respectively, in the analysis using the receiver operating characteristic curve. All AUC values were over 0.90. Therefore, KBDEFS is a reliable and valid screening instrument for diagnosing adult ADHD. In an assessment of the sensitivity and specificity of the cutoff scores, a cutoff of 183.5 points for the K-BDEFS total score, 26.5 points for the EF symptom count, and 23.5 points for the ADHD-EF index showed a reliable sensitivity and specificity above 80%. Conclusion To the best of the authors’ knowledge, this is the first study to examine the predictive validity and clinical utility of K-BDEFS in adult ADHD. The results suggest that the K-BDEFS could be used as a valid and reliable tool for the diagnosis and clinical intervention of adult ADHD.

OBJECTIVE: This study aimed to clarify the role of acute alcohol use and alcohol use disorder in individuals exhibiting suicidal behaviors, including repetition of suicide attempt. METHODS: Data pertaining to 691 suicide attempters who had visited an emergency center and had been followed-up from 2010 to 2015 were gathered. Participants were categorized into following three groups according to alcohol use pattern at the time of the suicide attempt: 1) suicide attempters with neither alcohol use disorder nor acute alcohol consumption (NAU), 2) suicide attempters who had used alcohol during the suicide attempt but did not have alcohol use disorder (AAU), and 3) suicide attempters with alcohol use disorder (AUD). Group comparisons and multivariate Cox proportional models for suicidal behavior were used for statistical analysis. RESULTS: AUD have been shown to have lower lethality of suicide attempt but higher risk of suicide reattempts in the future. Furthermore, positive relationships between suicide reattempts and AUD persisted throughout the longer period than other groups. CONCLUSION Suicide attempters with AUD should be considered a high-risk group for suicide reattempts in future, and this group should be followed-up for a longer period with specialized care program.

OBJECTIVE: Severity of nausea and vomiting of pregnancy (NVP) is associated with adverse pregnancy outcomes and poorer quality of life (QOL). The aim of this study was to evaluate the severity of NVP and maternal well-being status using the Pregnancy-Unique Quantification of Emesis and Nausea (PUQE) scale in a Korean population. METHODS: A total of 527 pregnant women who were receiving prenatal care at 4 hospitals were asked to participate in the study between January 2015 and June 2015. The severity of NVP was evaluated by the PUQE scale and maternal well-being status was evaluated using the visual analogue scale (VAS). Statistical analyses were performed to determine the risk factors associated with NVP and the associations between the severity of NVP and QOL. RESULTS: Among the 472 eligible pregnant women, 381 (80.7%) were suffering from NVP during pregnancy. No significant differences (P>0.05) were observed in any of the variables between the 2 study groups, with the exception of smoking, alcohol consumption, and history of NVP. NVP history was found to be the most powerful risk factor (adjusted odds ratio, 11.6; 95% confidence interval, 4.7–28.7). The correlation coefficient (r) between the VAS scores of maternal well-being status and PUQE severity was −0.25 (r 2=0.062; P-< 0.001). CONCLUSION: In this study, an explicit decline in maternal well-being status was observed according to severity of NVP. The PUQE scale may be of help to clinicians, healthcare providers, and researchers because of its simplicity and usefulness as a tool for NVP evaluation.

OBJECTIVES: The aims of this study were to investigate the psychopathology in adolescents with internalizing disorder using the self-report version of Strengths and Difficulties Questionnaire (SDQ-SR) and the Minnesota Multiphasic Personality Inventory for adolescents (MMPI-A), and to explore the complementarity between these two inventories for diagnostic assessment. METHODS: Ninety-one patients aged 13–17 were divided into two groups by clinical diagnosis, 44 with internalizing disorder and 47 comparison group with other disorders. The data of SDQ-SR and MMPI-A completed by them were analyzed for the ability to predict internalizing disorder. RESULTS: The logistic regression analysis revealed that diagnostic predictability increased by 2.27 times with every 1 point of SDQ-SR emotional symptom score increment. Comparison of ROC curves for internalizing disorders showed that the SE and SP of SDQ-SR emotional symptom with score over 4 was 88.94 and 78.72, respectively. For A-anx of MMPI-A with score over 56, SE and SP was 77.27 and 74.47, respectively. However, combination of these scales could not enhance the predictability of diagnostic classification more than that of SDQ-SR emotional symptom alone. CONCLUSIONS: Emotional symptom scale of SDQ-SR and A-anx, A-aln, A and INTR of MMPI-A should be important subscales for diagnosing the internalizing disorder of adolescents, however, which needs to be examined further with a larger sample size including normal control group.
