In the present article, we provide a comprehensive review of the treatment strategies for obsessive-compulsive disorder (OCD), a common, chronic, and often debilitating disorder, characterized by overwhelming obsessions and compulsions.OCD typically starts in childhood or adolescence and persists throughout life, causing functional impairment across multiple domains. The article begins by describing the historical concepts of OCD from religious and guilt-based explanations to psychoanalytic perspectives, and then explores the changing understanding of OCD as a treatable condition. Recent advances include the development of evidence-based psychological treatments, such as exposure and response prevention, and pharmacological treatments, such as selective serotonin reuptake inhibitors. The latest version of the Diagnostic and Statistical Manual of Mental Disorders, and the International Classification of Diseases, has removed OCD from the anxiety disorder grouping and regrouped it into obsessive-compulsive and related disorders. We conclude by highlighting the current state of knowledge and development in the clinical management of OCD, including recommendations for first- and second-line treatments, alternative, or augmentative strategies for and novel agents under investigation for OCD. In future, the latest advances in neuroimaging, electrophysiology, digital technology, and data-driven analysis will help elucidate the pathophysiology of OCD and develop personalized intervention strategies.

PURPOSE: To determine the effects of provision of information on mother's problem focused coping ability during their child's intravenous procedure. METHODS: Data were collected from 56 mothers whose children have admitted to pediatric ward in the hospital. The participants included 27 intervention group mothers and 29 control group mothers. For the information intervention, "Programmed Information for Parental Coping before Intravenous Procedure (PIPC-IP)", video program was made based on self-regulation theory for the experimental group mothers. Mother's coping ability was measured by parental supportive behavior, parental beliefs and Profile of Mood State (POMS). RESULTS: Mothers who received PIPC-IP showed significantly higher levels of supportive behavior (t = 3.55, p = .005) and Parental Beliefs (t = 2.95, p = .005), but no significant difference in negative mood on POMS (t = .15, p = .87) compared to mothers in the control group. CONCLUSIONS: These results demonstrate that PIPC-IP is an effective intervention to increase the supportive behaviors and beliefs of mothers' problem focused coping ability but not the negative mood.

The purpose of this study was to develop and evaluate psychometrically the Korean version of the Primary Care Posttraumatic Stress Disorder Screen for the Diagnostic and Statistical Manual-fifth edition (K-PC-PTSD-5). In total, 252 participants were interviewed with the Structured Clinical Interview for Diagnostic and Statistical Manual-fifth edition-research version (SCID-5-RV). The K-PC-PTSD-5 showed good internal consistency (α = 0.872), test-retest reliability (r = 0.89), and concurrent validity (r = 0.81). A score of 3 was identified as the threshold for clinically significant posttraumatic stress disorder (PTSD) symptoms. Overall, the results indicate that the K-PC-PTSD-5 is a useful, timesaving instrument for screening PTSD symptoms.

Objective: This study presents the reliability and validity of the Korean version of the post-traumatic stress disorder (PTSD) checklist for the Diagnostic and Statistical Manual for Mental Disorders-fifth edition (DSM-5) (K-PCL-5) and the short form (K-PCL-5-S). Methods: Seventy-one subjects with PTSD, 74 subjects with mood or anxiety disorders, and 99 healthy controls were enrolled. The Korean version of the Structured Clinical Interview for DSM-5-research version was used to confirm the presence of PTSD. The Beck Depression Inventory-II (BDI-II), Beck Anxiety Inventory (BAI), Impact of Event Scale-Revised (IES-R), and Spielberger State Trait Anxiety Inventory (STAI) were used to evaluate the concurrent validity of the K-PCL-5 and K-PCL-5-S. Results: It presented good internal consistency (Cronbach’s α=0.93) and test-retest reliability (r=0.90). The K-PCL-5 and K-PCL-5-S were highly correlated with the BDI-II, BAI, IES-R, STAI-S, and STAI-T. The suggested cutoff score for PTSD was 33 for the K-PCL-5 with a sensitivity of 88.51 and specificity of 89.09, and 6 for the K-PCL-5-S with a sensitivity of 91.95 and specificity of 89.09. The data were best explained with a one-factor model. Conclusion These results demonstrated the good reliability and validity of the K-PCL-5 and K-PCL-5-S, and their suitability as simple tools for PTSD assessment.

BACKGROUND: The purpose of this study was to localize the cortical regions reflected by overlying scalp electrodes. METHODS: We enrolled 10 patients with epilepsy (5 males, mean age 29.7 years old). Thin slice coronal T1 weighted MR images were obtained and then scalp EEG electrodes were placed based on an international 10-20 system. Cortical locations of scalp electrodes were determined using a real-time frameless stereotactic image guidance system, Brainsight(R). RESULTS: The locations of 19 scalp electrodes were marked on the 3D rendered cortical surface of one representative patient's MRI; Fp1 (Fp2) on the anterior pole of the middle frontal gyrus, Fz on the mid-point of the interhemispheric fissure in the frontal lobe, F3 (F4) on the mid-portion of the middle frontal gyrus, F7 (F8) on the pars triangularis of the inferior frontal gyrus, Cz on the interhemispheric fissure where a lateral precentral gyrus starts, C3 (C4) scattered around postcentral gyrus, T3 (T4) on the middle temporal gyrus, P3 (P4) on the angular gyrus, Pz on the mid-point of the interhemispheric fissure in the parietal lobe, T5 (T6) on the posterior part of the inferior temporal gyrus, and O1 (O2) on the occipital pole. CONCLUSIONS: The locations of scalp electrodes were well correlated with conventional concepts of their cortical locations. The individual differences of the scalp electrode locations may be due to the different sizes and morphologies of the brains in each of the patients. Real time cortical localization of scalp electrodes using the Frameless Stereotactic Image Guidance System may provide useful information for more accurate localization of focal cerebral activity in partial epilepsy patients.

In determination of brain death, brain CT angiography (CTA) can be used as a new ancillary test to assist EEG which is the current gold standard. We report a patient with barbiturate coma therapy whose CTA showed weak filling of the internal carotid artery and its branches when his EEG demonstrated regional beta activities in the corresponding area, which finally disappeared. Combined use of CTA and serial EEGs would be helpful as brain death testing in a patient with barbiturate coma therapy.

Objective: The abuse of prescription drugs and over-the-counter medicines has been a major issue addressed as a serious public health problem worldwide. This study explored factors contributing to substance abuse in Korea by examining the status of substance abuse among Korean adults and evaluating their knowledge, attitudes, and intentions toward substance abuse. Methods: Data were collected online from a sample of participants 19 years old or older from May 20 to June 1, 2020 (n=1,020). The survey consisted of questions on demographics, perceptions of drug risk, motives for drug use, and attitudes toward drug addiction treatment. Principal component and multiple logistic regression analyses were used to explore the factors contributing to the perception of drug abuse. Results: In the multivariate regression analysis, overconfidence in handling drug usage, acceptance of addictive substances, and affirmation of public support for drug abuse were associated with opioid abuse (Nagelkerke R2=0.486), and additionally affirmation of legal cannabis usage and motivation to use diet pills were associated with diet pill abuse (Nagelkerke R2=0.569). Conclusion The findings of this study suggest that the actual situation of substance abuse among Korean adults increases awareness of and attitudes toward drug use related to substance abuse.

BACKGROUND: For diagnosis of post-traumatic stress disorder (PTSD), the Clinician-Administered PTSD Scale (CAPS) is one of the most widely used structured diagnostic interviews. METHODS: In this study, we aimed to develop and validate the Korean version of CAPS for the Diagnostic and Statistical Manual of Mental Disorders, 5th edition ([DSM-5] K-CAPS-5). Seventy-one subjects with PTSD, 74 with mood disorder or anxiety disorder, and 99 as healthy controls were enrolled. The Korean version of the structured clinical interview for DSM-5-research version was used to assess the convergent validity of K-CAPS-5. BDI-II, BAI, IES-R, and STAI was used to evaluate the concurrent validity. RESULTS: All subjects completed various psychometric assessments including K-CAPS-5. K-CAPS-5 presented good internal consistency (Cronbach's α = 0.92) and test-retest reliability (r = 0.91). K-CAPS-5 showed strong correlations with the structured clinical interview for DSM-5 PTSD (k = 0.893). Among the three subject groups listed above there were significant differences in the K-CAPS-5 total score. The data were best explained by a six-factor model. CONCLUSION: These results demonstrated the good reliability and validity of K-CAPS-5 and its suitability for use as a simple but structured instrument for PTSD assessment.

Objective: This study aims to understand the attitudes, stigma, and discrimination of the general adult population toward drug addiction. Methods: We conducted a cross-sectional nationwide survey with 1,020 Korean adults using an Internet web-based panel. Self-reported data were collected on demographics, experience with substance abuse, perceptions of narcotic analgesic use, beliefs about the legalization of cannabis use, coping with substance abuse and addiction, and perceptions of drug risks. All statistical analysis in this study utilized the IBM SPSS Statistics 26 program. Results: In this study, 1.6% of the participants reported abuse of opioid analgesics, 88.0% reported negative perceptions of drug addiction, and 76.9% reported agreeing to unfair treatment of drug addicts. Logistic regression analysis found that perceived stigma was more prevalent among women (odd ratio [OR]=2.087, p<0.01), old adults (OR=1.939, p<0.01), those with no personal experience of opioid misuse (OR=8.172, p<0.05), and those who were non-smoking (OR=2.011, p<0.01). In addition, the discriminatory attitude was more prevalent among participants with higher income (OR=1.989, p<0.001) and those who are non-smoking (OR=1.608, p<0.05). Conclusion This study provides information and guidelines for public intervention in drug addiction by identifying factors influencing social stigma and discriminatory behaviors toward drug addiction. The findings suggest that education on drug addiction prevention for the general adult population is necessary, and this education should include knowledge on coping with drug addiction and reducing stigma and discrimination toward drug addicts.

Objective: The Impact of Event Scale–Revised (IES-R) is a widely used self-report for assessing posttraumatic stress disorder (PTSD), originally aligned with Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV diagnostic criteria. This study aimed to evaluate the applicability of the IES-R under the DSM-5 guidelines and establish a cutoff point for DSM-5 PTSD diagnosis. Methods: A total of 238 participants recruited from multiple psychiatric centers, including 67 patients with PTSD, 72 patients with psychiatric controls, and 99 healthy controls, were included in the study. All participants completed the Korean version of the Structured Clinical Interview for the DSM-5 research version to confirm the presence of PTSD, the Korean version of PTSD Checklist for DSM-5 (PCL-5), the Beck Depression Inventory-II, the Beck Anxiety Inventory, and the Spielberger State Trait Anxiety Inventory. Results: The IES-R demonstrated good internal consistency and a high correlation with the PCL-5. Through factor analysis, 5 distinct dimensions emerged within the IES-R: sleep disturbance, intrusion, hyperarousal, avoidance, and numbness-dissociation. A proposed cutoff score of 25 on the IES-R was suggested for identifying patients with PTSD. Conclusion These findings underscore the scale’s concurrent validity with the DSM-5 PTSD criteria and its effectiveness as a screening tool. Implementing a cutoff score of 25 on the IES-R can enhance its utility in identifying DSM-5 PTSD cases.
