An exploratory study on spatiotemporal clustering of suicide in Korean adolescents. Child Adolesc Psychiatry Ment Health 2024; 18:54. [PMID: 38730504 PMCID: PMC11088016 DOI: 10.1186/s13034-024-00745-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/18/2024] [Accepted: 05/01/2024] [Indexed: 05/13/2024] Open
Abstract
BACKGROUND Adolescent suicides are more likely to form clusters than those of other age groups. However, the definition of a cluster in the space-time dimension has not been established, neither are the factors contributing to it well known. Therefore, this study aimed to identify space-time clusters in adolescent suicides in Korea and to examine the differences between clustered and non-clustered cases using novel statistical methods. METHODS From 2016 to 2020, the dates and locations, including specific addresses from which the latitude and longitude of all student suicides (aged 9-18 years) in Korea were obtained through student suicide reports. Sociodemographic characteristics of the adolescents who died by suicide were collected, and the individual characteristics of each student who died by suicide were reported by teachers using the Strengths and Difficulties Questionnaire (SDQ). Density-Based Spatial Clustering of Applications with Noise (DBSCAN) analysis was used to assess the clustering of suicides. RESULTS We identified 23 clusters through the data analysis of 652 adolescent suicides using DBSCAN. By comparing the size of each cluster, we identified 63 (9.7%) spatiotemporally clustered suicides among adolescents, and the temporal range of these clusters was 7-59 days. The suicide cluster group had a lower economic status than the non-clustered group. There were no significant differences in other characteristics between the two groups. CONCLUSION This study has defined the space-time cluster of suicides using a novel statistical method. Our findings suggest that when an adolescent suicide occurs, close monitoring and intervention for approximately 2 months are needed to prevent subsequent suicides. Future research using DBSCAN needs to involve a larger sample of adolescents from various countries to further corroborate these findings.

Preventive effect of aripiprazole once-monthly on relapse into mood episodes in bipolar disorder: A multicenter, one-year, retrospective, mirror image study. J Affect Disord 2024; 351:381-386. [PMID: 38302064 DOI: 10.1016/j.jad.2024.01.257] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/29/2023] [Revised: 01/25/2024] [Accepted: 01/28/2024] [Indexed: 02/03/2024]
Abstract
BACKGROUND We conducted a one-year, retrospective, mirror-image study to investigate the clinical effectiveness and safety of aripiprazole once monthly (AOM) in patients with bipolar disorder (BD). We compared pre-treatment conditions with outcomes after 12 months of AOM treatment. METHODS Seventy-five bipolar patients were recruited from 12 hospitals in Korea. We included 75 patients with BD who had received at least three AOM treatments from September 2019 to September 2022 and had accessible electronic medical record (EMRs) for the year before and after the baseline visit. RESULTS The overall number of mood episodes significantly decreased from a mean of 1.5 ± 1.2 episodes pre-AOM to 0.5 ± 1.2 episodes post-AOM. Manic episodes significantly decreased from 0.8 ± 0.8 episodes pre-AOM to 0.2 ± 0.5 episodes post-AOM, and depressive episodes significantly decreased from 0.5 ± 0.8 episodes pre-AOM to 0.2 ± 0.6 episodes post-AOM (p = 0.017). Moreover, the number of psychiatric medications and pills and the proportion of patients treated with complex polypharmacy were significantly decreased post-AOM. LIMITATIONS The small sample size was insufficient to fully represent the entire population of individuals with BD, and potential selection bias was introduced due to only including subjects who received AOM three or more times. CONCLUSION The results of this study suggest that AOM can reduce mood episode relapse and may be clinically beneficial in the treatment of BD patients, potentially reducing issues associated with polypharmacy in some individuals.

Latent Classes based on Clinical Symptoms of Military Recruits with Mental Health Issues and Their Distinctive Clinical Responses to Treatment over 6 Months. CLINICAL PSYCHOPHARMACOLOGY AND NEUROSCIENCE : THE OFFICIAL SCIENTIFIC JOURNAL OF THE KOREAN COLLEGE OF NEUROPSYCHOPHARMACOLOGY 2023; 21:778-786. [PMID: 37859451 PMCID: PMC10591162 DOI: 10.9758/cpn.23.1061] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/01/2023] [Revised: 03/09/2023] [Accepted: 03/10/2023] [Indexed: 10/21/2023]
Abstract
Objective : This study aimed (1) to identify distinct subgroups of psychiatric patients referred for a mental health certificate for military service suitability and (2) to determine whether there is a difference in clinical features such as treatment responsiveness and prognosis among certain subgroups. Methods : We conducted latent profile analysis (LPA) using the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) clinical profiles of the participants. Linear mixed model analysis was performed to examine changes in the severity of clinical symptoms and functional level according to the treatment period of the latent classes derived from the LPA. Results : The results indicated that the best-fitting model was a three-class model, comprising Class 1 (mild maladjustment), Class 2 (neurotic depression and anxiety), and Class 3 (highly vulnerable and hypervigilant). We demonstrated that the three subgroups displayed different characteristics in treatment responsiveness and clinical course based on their Clinical Global Impression-Severity and Global Assessment of Functioning scores over a treatment period of 6 months. While subjects in Classes 1 and 2 significantly improved over 6 months, those in Class 3 showed little or no improvement in our clinical parameters. Conclusion : This study has yielded data with clinical implications for treatment planning and interventions for each subgroup classified that were based on MMPI-2 clinical profiles of military recruits who might be maladjusted to serve.

Development of a Guideline for Antipsychotic-induced Hyperprolactinemia in Korea Using the ADAPTE Process. CLINICAL PSYCHOPHARMACOLOGY AND NEUROSCIENCE : THE OFFICIAL SCIENTIFIC JOURNAL OF THE KOREAN COLLEGE OF NEUROPSYCHOPHARMACOLOGY 2023; 21:447-456. [PMID: 37424413 PMCID: PMC10335910 DOI: 10.9758/cpn.22.979] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/24/2022] [Revised: 04/11/2022] [Accepted: 04/11/2022] [Indexed: 07/11/2023]
Abstract
Objective To develop an evidence-based guideline for the diagnosis and treatment of antipsychotic-induced hyperprolactinemia by adapting existing high-quality clinical guidelines with a view to improve the clinical symptoms and long-term quality of life of patients by providing appropriate management. Methods This guideline was developed according to the ADAPTE methodology. The adaptation process included determining key health questions, systematically searching and screening guidelines, evaluating the quality and contents of these guidelines, deriving recommendations for key questions, and performing a peer review. The selection criteria for the guideline search were (1) evidence-based guidelines, (2) published within the last 5 years, and (3) written in English or Korean. Results After evaluating the quality and content, we finally selected three guidelines for adaptation. The final output of the development process was 25 recommendations for 10 key questions. We adopted the Agency for Health Research Quality methodology and presented the level of evidence from levels I to IV. In addition, we defined the recommendation grades from grade A (strongly recommended) to D (no recommendation) based on the level of evidence and clinical significance of the recommendation. Conclusion The development and dissemination of the adapted guideline is expected to increase the certainty of medical decision making and improve the quality of medical care. Further studies on the effectiveness and applicability of the developed guideline are necessary.

Korean Medication Algorithm Project for Bipolar Disorder 2022: Comparisons with Other Treatment Guidelines. CLINICAL PSYCHOPHARMACOLOGY AND NEUROSCIENCE : THE OFFICIAL SCIENTIFIC JOURNAL OF THE KOREAN COLLEGE OF NEUROPSYCHOPHARMACOLOGY 2023; 21:32-48. [PMID: 36700310 PMCID: PMC9889890 DOI: 10.9758/cpn.2023.21.1.32] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Revised: 09/15/2022] [Accepted: 09/19/2022] [Indexed: 01/27/2023]
Abstract
The objective of this study was to compare recommendations of the Korean Medication Algorithm Project for Bipolar Disorder 2022 (KMAP-BP 2022) with other recently published guidelines for treating bipolar disorder. We reviewed a total of six recently published global treatment guidelines and compared treatment recommendation of the KMAP-BP 2022 with those of other guidelines. For initial treatment of mania, there were no significant differences across treatment guidelines. All guidelines recommended mood stabilizer (MS) or atypical antipsychotic (AAP) monotherapy or a combination of an MS with an AAP as a first-line treatment strategy in a same degree for mania. However, the KMAP-BP 2022 recommended MS + AAP combination therapy for psychotic mania, mixed mania and psychotic depression as treatment of choice. Aripiprazole, quetiapine and olanzapine were the first-line AAPs for nearly all phases of bipolar disorder across guidelines. Some guideline suggested olanzapine is a second-line options during maintenance treatment, related to concern about long-term tolerability. Most guidelines advocated newer AAPs (asenapine, cariprazine, long-acting injectable risperidone, and aripiprazole once monthly) as first-line treatment options for all phases while lamotrigine was recommended for depressive and maintenance phases. Lithium and valproic acid were commonly used as MSs in all phases of bipolar disorder. KMAP-BP 2022 guidelines were similar to other guidelines, reflecting current changes in prescription patterns for bipolar disorder based on accumulated research data. Strong preference for combination therapy was characteristic of KMAP-BP 2022, predominantly in the treatment of psychotic mania, mixed mania and psychotic depression.

Psychometric Properties of the Korean Version of Functioning Assessment Short Test in Bipolar Disorder. CLINICAL PSYCHOPHARMACOLOGY AND NEUROSCIENCE : THE OFFICIAL SCIENTIFIC JOURNAL OF THE KOREAN COLLEGE OF NEUROPSYCHOPHARMACOLOGY 2023; 21:188-196. [PMID: 36700325 PMCID: PMC9889907 DOI: 10.9758/cpn.2023.21.1.188] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/25/2022] [Revised: 08/04/2022] [Accepted: 08/05/2022] [Indexed: 01/27/2023]
Abstract
Objective The Functioning Assessment Short Test (FAST) is a relatively specific test for bipolar disorders designed to assess the main functioning problems experienced by patients. This brief instrument includes 24 items assessing impairment or disability in 6 domains of functioning: autonomy, occupational functioning, cognitive functioning, financial issues, interpersonal relationships, and leisure time. It has already been translated into standardized versions in several languages. The aim of this study is to measure the validity and reliability of the Korean version of FAST (K-FAST). Methods A total of 209 bipolar disorder patients were recruited from 14 centers in Korea. K-FAST, Young Mania Rating Scale (YMRS), Bipolar Depression Rating Scale (BDRS), Global Assessment of Functioning (GAF) and the World Health Organization Quality of Life Assessment Instrument Brief Form (WHOQOL-BREF) were administered, and psychometric analysis of the K-FAST was conducted. Results The internal consistency (Cronbach's alpha) of the K-FAST was 0.95. Test-retest reliability analysis showed a strong correlation between the two measures assessed at a 1-week interval (ICC = 0.97; p < 0.001). The K-FAST exhibited significant correlations with GAF (r = -0.771), WHOQOL-BREF (r = -0.326), YMRS (r = 0.509) and BDRS (r = 0.598). A strong negative correlation with GAF pointed to a reasonable degree of concurrent validity. Although the exploratory factor analysis showed four factors, the confirmatory factor analysis of questionnaires had a good fit for a six factors model (CFI = 0.925; TLI = 0.912; RMSEA = 0.078). Conclusion The K-FAST has good psychometric properties, good internal consistency, and can be applicable and acceptable to the Korean context.

The Korean Medication Algorithm Project for Depressive Disorder (KMAP-DD): Changes in Preferred Treatment Strategies and Medications over 20 Years and Five Editions. J Clin Med 2023; 12:jcm12031146. [PMID: 36769798 PMCID: PMC9917906 DOI: 10.3390/jcm12031146] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2022] [Revised: 01/27/2023] [Accepted: 01/30/2023] [Indexed: 02/04/2023] Open
Abstract
BACKGROUND The Korean Medication Algorithm Project for Depressive Disorder (KMAP-DD) is an expert consensus guideline for depressive disorder created in 2002, and since then, four revisions (2006, 2012, 2017, 2021) have been published. In this study, changes in the content of the KMAP-DD survey and recommendations for each period were examined. METHODS The development process of the KMAP-DD was composed of two stages. First, opinions from experts with abundant clinical experience were gathered through surveys. Next, a final guideline was prepared through discussion within the working committee regarding the suitability of the results with reference to recent clinical studies or other guidelines. RESULTS In mild depressive symptoms, antidepressant (AD) monotherapy was preferred, but when severe depression or when psychotic features were present, a combination of AD and atypical antipsychotics (AD + AAP) was preferred. AD monotherapy was preferred in most clinical subtypes. AD monotherapy was preferred for mild depressive symptoms, and AD + AAP was preferred for severe depression and depression with psychotic features in children, adolescents, and the elderly. CONCLUSIONS This study identified the changes in the KMAP-DD treatment strategies and drug preferences in each period over the past 20 years. This work is expected to aid clinicians in establishing effective treatment strategies.

CLINICAL PSYCHOPHARMACOLOGY AND NEUROSCIENCE : THE OFFICIAL SCIENTIFIC JOURNAL OF THE KOREAN COLLEGE OF NEUROPSYCHOPHARMACOLOGY 2022; 20:747-761. [PMID: 36263649 PMCID: PMC9606436 DOI: 10.9758/cpn.2022.20.4.747] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/27/2022] [Revised: 07/05/2022] [Accepted: 07/06/2022] [Indexed: 08/30/2023]
Abstract
OBJECTIVE We revised the Korean Medication Algorithm Project for Bipolar Disorder (KMAP-BP), first published in 2002 and revised in 2006, 2010, 2014, and 2018, to reflect recent progress in the treatment of bipolar disorder. METHODS The questionnaires consisted of 56 items for adult patients and 7 items for child/adolescent patients, and were used to obtain the consensus of experts regarding pharmacological treatment strategies for various phases of bipolar disorder. The review committee included 87 Korean psychiatrists and 40 child and adolescent psychiatry experts. RESULTS For treatment of manic episodes, a combination of a mood stabilizer (MS) and atypical antipsychotics (AAP), or monotherapy with MS or AAP were recommended as first-line treatments. Combinations of MS and AAP, or AAP and lamotrigine (LMT) were recommended as first-line treatments for depressive episodes regardless of the severity. Monotherapy with MS, AAP, or LMT were also first-line treatments for mild to moderate depressive episodes. For mixed features, a combination of MS and AAP, or monotherapy with AAP or MS were recommended as first-line treatments, and a combination of AAP and LMT, or MS and LMT were the first-line treatments for depressive mixed state. CONCLUSION The recommendations of the KMAP-BP 2022 have changed from the previous version, to reflect the evolution of the social culture and healthcare system in Korea and recent evidence regarding pharmacotherapy of bipolar disorder. The KMAP-BP 2022 provides clinicians with a wealth of information regarding appropriate strategies to treat patients with bipolar disorder.

Abstract
The Korean Medication Algorithm Project for Depressive Disorder (KMAP-DD) first was published in 2002, and has been revised four times, in 2006, 2012, 2017, and 2021. In this review, we compared recommendations from the recently revised KMAP-DD 2021 to four global clinical practice guidelines (CPGs) for depression published after 2010. The recommendations from the KMAP-DD 2021 were similar to those from other CPGs, although there were some differences. The KMAP-DD 2021 reflected social culture and the healthcare system in Korea and recent evidence about pharmacotherapy for depression, as did other recently published evidence-based guidelines. Despite some intrinsic limitations as an expert consensus-based guideline, the KMAP-DD 2021 can be helpful for Korean psychiatrists making decisions in clinical settings by complementing previously published evidence-based guidelines, especially for some clinical situations lacking evidence from rigorously designed clinical trials.

Abstract
OBJECTIVE This study investigated the prevalence and comorbidities of attention deficit hyperactivity disorder (ADHD) among adults and children/adolescents in Korea. METHODS This study used data from the Korea Health Insurance Review and Assessment Service collected from 2008 to 2018. Study participants comprised patients with at least one diagnosis of ADHD (International Statistical Classification of Diseases and Related Health Provisions, 10th revision code F90.0). Prevalence rates and psychiatric comorbidities were also analyzed. RESULTS We identified 878,996 patients diagnosed with ADHD between 2008 and 2018. The overall prevalence rate of diagnosed ADHD increased steeply from 127.1/100,000 in 2008 to 192.9/100,000 in 2018; it increased 1.47 times in children/adolescents (≤ 18 years) and 10.1 times in adults (> 18 years) during this period. Among adult and children/ adolescent ADHD patients, 61.84% (95% confidence interval [95% CI] 61.74-61.93) and 78.72% (95% CI 78.53- 78.91) had at least one psychiatric comorbidity, respectively. CONCLUSION Our results showed that the prevalence rate of diagnosed ADHD has increased in Korea; however, it is lower than the global average. Further studies are required to identify and treat vulnerable populations appropriately.

Abstract
Objective In the 19 years since the Korean College of Neuropsychopharmacology and the Korean Society for Affective Disorders developed the Korean Medication Algorithm Project for Depressive Disorder (KMAP-DD) in 2002, four revisions have been conducted. Methods To increase survey efficiency in this revision, to cover the general clinical practice, and to compare the results with previous KMAP-DD series, the overall structure of the questionnaire was maintained. The six sections of the questionnaire were as follows: 1) pharmacological treatment strategies for major depressive disorder (MDD) with/without psychotic features; 2) pharmacological treatment strategies for persistent depressive disorder and other depressive disorder subtypes; 3) consensus for treatment-resistant depression; 4) the choice of an antidepressant in the context of safety, adverse effects, and comorbid physical illnesses; 5) treatment strategies for special populations (children/adolescents, elderly, and women); and 6) non-pharmacological biological therapies. Recommended first-, second-, and third-line strategies were derived statistically. Results There has been little change in the four years since KMAP-DD 2017 due to the lack of newly introduced drug or treatment strategies. However, shortened waiting time between the initial and subsequent treatments, increased preference for atypical antipsychotics (AAPs), especially aripiprazole, and combination strategies with AAPs yield an active and somewhat aggressive treatment trend in Korea. Conclusion We expect KMAP-DD to provide clinicians with useful information about the specific strategies and medications appropriate for treating patients with MDD by bridging the gap between clinical real practice and the evidence-based world.

Abstract
OBJECTIVES The Korean Medication Algorithm Project for Bipolar Disorder (KMAP-BP) is based on expert consensus and has been revised five times since 2002. This study evaluated the changes in treatment strategies advocated by the KMAP-BP over time. METHODS The five editions of the KMAP-BP were reviewed, and the recommendations of the KMAP-BP were compared with those of other bipolar disorder (BP) treatment guidelines. RESULTS The most preferred option for the initial treatment of mania was a combination of a mood stabilizer (MS) and an atypical antipsychotic (AAP). Either MS or AAP monotherapy was also considered a first-line strategy for mania, but not for all types of episodes, including mixed/psychotic mania. In general, although lithium and valproic acid were commonly recommended, valproic acid has been increasingly preferred for all phases of BP. The most notable changes over time included the increasing preference for AAPs for all phases of BP, and lamotrigine for the depressive and maintenance phases. The use of antidepressants for BP has gradually decreased, but still represents a first-line option for severe and psychotic depression. CONCLUSIONS In general, the recommended strategies of the KMAP-BP were similar to those of other guidelines, but differed in terms of the emphasis on rapid effectiveness, which is often desirable in actual clinical situations. The major limitation of the KMAP-BP is that it is a consensus-based rather than an evidence-based tool. Nevertheless, it may confer advantages in actual clinical practice.

Effects of Paliperidone Palmitate on Healthcare Utilization and Costs for Patients with Schizophrenia: A Claim-based Mirror-image Study in South Korea. CLINICAL PSYCHOPHARMACOLOGY AND NEUROSCIENCE 2020; 18:303-310. [PMID: 32329310 PMCID: PMC7242100 DOI: 10.9758/cpn.2020.18.2.303] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/01/2019] [Revised: 12/05/2019] [Accepted: 12/18/2019] [Indexed: 12/12/2022]
Abstract
Objective Long-acting injectable (LAI) antipsychotics, such as paliperidone palmitate (PP), are known to improve treatment adherence in patients with schizophrenia, which can lead to reductions in relapse and hospitalization rates. However, relatively few studies have demonstrated the economic impact of LAIs, especially in Asian populations. Methods We conducted a claim-based mirror-image study to explore changes in healthcare utilization and associated costs, among 1,272 South Korean patients with schizophrenia (ICD-10-CM code F20), between the 1-year periods before and after the initiation of PP treatment. Results Patients accessed outpatient services more frequently after versus before starting PP treatment, with the number of prescription days increasing by 133.45 (p < 0.0001) and the associated costs increasing by USD 1,497.15 (p < 0.0001). The number of admission days was reduced by 11.33 after starting PP treatment (p < 0.0001) and the associated costs were reduced by USD 1,220.75 (p < 0.0001). However, admission cost savings were different according to patients’ oral drug compliance. The daily dosages for benztropine, procyclidine, and propranolol decreased, showing that there were fewer side-effects after PP-treatment (p < 0.0001). Conclusion Although the high acquisition cost of PP has been regarded as an obstacle to its clinical use, our results imply that the high prescription costs for PP may be counterbalanced by the reduced admission costs associated with its use. Economic outcomes for patients treated with LAIs should be investigated further to help healthcare decision-makers and providers to determine the value of LAIs relative to other treatment medications.

Abstract
Objective Whether long-acting injectable antipsychotics (LAI) are superior to oral antipsychotics remains a controversial question, and results vary depending on the study design. Our study was performed to compare outcomes of oral antipsychotics and paliperidone palmitate (PP) in clinical practice by investigating the numbers of admissions and bed days. Methods We performed a retrospective observational mirror-image study at a single medical center, reviewing medical charts to obtain the clinical data. Forty-six patients with a diagnosis of schizophrenia or schizoaffective disorder who had received at least two doses of PP were included in the analysis. The Wilcoxon signed-rank test was used to compare the numbers of bed days and admissions 1 year before starting PP with those numbers at 1 year after. Results The mean number of admissions fell from 0.83 to 0.17 per patient (p < 0.0002), and the median fell from 1 to 0. The mean number of bed days decreased significantly, from 24.85 to 8.74 days (p < 0.006). The outcomes remained similar in sensitivity analyses set up with different mirror points. Conclusion Our results indicate that initiating PP reduced the mean numbers of hospital admissions and bed days compared with prior oral medication. LAIs may thus be cost effective in practice; its use bringing about cost reductions greater than its purchase cost.

The prevalence and diagnostic classification of mixed features in patients with major depressive episodes: A multicenter study based on the DSM-5. Int J Methods Psychiatr Res 2019; 28:e1773. [PMID: 30786322 PMCID: PMC6877217 DOI: 10.1002/mpr.1773] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/04/2018] [Revised: 01/09/2019] [Accepted: 01/12/2019] [Indexed: 01/12/2023] Open
Abstract
OBJECTIVES The purpose of this study was to evaluate the prevalence of mixed features using the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) and to examine how patients with mixed states would be classified using the DSM-5. METHODS In total, 12 hospitals participated in this study, and data on the demographic characteristics and clinical diagnoses of patients treated between October 2013 and September 2016 were obtained. We reviewed the data for opposite-polarity symptoms according to the DSM-5 criteria and the research-based diagnostic criteria. RESULTS Of the 859 patients included in the final analysis, the prevalence of mixed features in patients with major depressive episodes based on the DSM-5 remained low. Patients with major depressive disorder were more likely to be classified as experiencing anxious distress and/or a cluster-B personality disorder in mixed state patients not diagnosed with DSM-5 mixed features, whereas more mixed state patients with bipolar disorder were diagnosed with mixed features using the DSM-5. CONCLUSIONS The prevalence of mixed features did not increase significantly when the DSM-5 was used, and patients with mixed states were more likely to be classified as having anxious distress and/or a cluster-B personality disorder in addition to mixed features.

Abstract
OBJECTIVES This study aimed to identify the specific relationship between subdomains of religious variables and cognitive functions in outpatients with Alzheimer's disease (AD). METHODS We recruited 325 patients with AD from a psychiatry outpatient clinic. The Korean version of the Consortium to Establish a Registry for Alzheimer's Disease and the Duke University Religion Index were used to assess cognitive functions and religiosity. We performed structural equation modeling and partial correlation analysis after controlling for demographic data. RESULTS The model in which religiosity beneficially affects cognitive functions showed acceptable model fit (root-mean-square error of approximation = 0.076, Tucker-Lewis index = 0.921, comparative fit index = 0.947). In the partial correlation analysis, organizational religious activity demonstrated positive relationships with memory ( r = 0.144, P = .010), language ( r = 0.149, P = .007), and constructional ability ( r = 0.191 P = .001). Nonorganizational religious activity and intrinsic religiosity were positively associated with memory ( r = 0.115, P = .040; r = 0.140, P = .012) and constructional ability ( r = 0.207, P = .000; r = 0.136, P = .015). CONCLUSIONS The findings suggest that religiosity positively affects cognitive functions and that each religious variable is related differently to the subdomains of cognitive functions in patients with AD.

Korean Medication Algorithm for Bipolar Disorder 2018: Comparisons with Other Treatment Guidelines. CLINICAL PSYCHOPHARMACOLOGY AND NEUROSCIENCE 2019; 17:155-169. [PMID: 30905116 PMCID: PMC6478090 DOI: 10.9758/cpn.2019.17.2.155] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 07/23/2018] [Revised: 07/30/2018] [Accepted: 07/31/2018] [Indexed: 12/29/2022]
Abstract
The objective of this study was to compare recommendations of the Korean Medication Algorithm Project for Bipolar Disorder 2018 (KMAP-BP 2018) with other recently published guidelines for treating bipolar disorder. We reviewed a total of five recently published global treatment guidelines and compared treatment recommendation of the KMAP-BP 2018 with those of other guidelines. For initial treatment of mania, there were no significant differences across treatment guidelines. All guidelines recommended mood stabilizer (MS) or atypical antipsychotic (AAP) monotherapy or a combination of an MS with an AAP as a first-line treatment strategy for mania. However, the KMAP-BP 2018 did not prefer monotherapy with MS or AAP for psychotic mania. Quetiapine, olanzapine and aripiprazole were the first-line AAPs for nearly all phases of bipolar disorder across guidelines. Most guidelines advocated newer AAPs as first-line treatment options for all phases while lamotrigine was recommended for depressive and maintenance phases. Lithium and valproic acid were commonly used as MSs in all phases of bipolar disorder. As research evidence accumulated over time, recommendations of newer AAPs (such as asenapine, cariprazine, paliperidone, lurasidine, long-acting injectable risperidone and aripiprazole once monthly) became prominent. KMAP-BP 2018 guidelines were similar to other guidelines, reflecting current changes in prescription patterns for bipolar disorder based on accumulated research data. Strong preference for combination therapy was characteristic of KMAP-BP 2018, predominantly in the treatment of psychotic mania and severe depression. Further studies were needed to address several issues identified in our review.

Korean Medication Algorithm Project for Bipolar Disorder 2018 (KMAP-BP 2018): Fourth Revision. CLINICAL PSYCHOPHARMACOLOGY AND NEUROSCIENCE 2018; 16:434-448. [PMID: 30466216 PMCID: PMC6245301 DOI: 10.9758/cpn.2018.16.4.434] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/09/2018] [Revised: 05/15/2018] [Accepted: 05/16/2018] [Indexed: 12/12/2022]
Abstract
Objective The Korean Medication Algorithm Project for Bipolar Disorder (KMAP-BP) was first published in 2002 through an expert consensus of opinion, and updated in 2006, 2010, and 2014. This study constitutes the fourth revision of the KMAP-BP. Methods A 50-item questionnaire was used to obtain the consensus of experts regarding pharmacological treatment strategies for various phases of adult bipolar disorder and six items for pediatric bipolar disorder. The review committee included 84 Korean psychiatrists and 43 child and adolescent psychiatry experts. Results The preferred first-step strategies for acute mania were the combination of a mood stabilizer (MS) and an atypical antipsychotic (AAP), MS monotherapy, and AAP monotherapy. A combination of a MS and an AAP, and AAP monotherapy were preferred for psychotic mania. The first-step strategies for mild to moderate bipolar depression were monotherapy with MS, AAP, or lamotrigine (LMT), and the combination of a MS and an AAP or LMT, or a combination of an AAP and LMT. The combination of two among a MS, AAP, and LMT were preferred for non-psychotic severe depression. A combination of a MS and an AAP or the combination of an AAP with an antidepressant or LMT were the first-line options for psychotic severe depression. Conclusion The recommendations of the KMAP-BP 2018 have changed from the previous version by reflecting recent developments in pharmacotherapy for bipolar disorder. KMAP-BP 2018 provides clinicians with a wealth of information regarding appropriate strategies for treating patients with bipolar disorder.

Modality-Specific Working Memory Systems Verified by Clinical Working Memory Tests. CLINICAL PSYCHOPHARMACOLOGY AND NEUROSCIENCE 2018; 16:489-493. [PMID: 30466221 PMCID: PMC6245297 DOI: 10.9758/cpn.2018.16.4.489] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/04/2017] [Revised: 09/06/2017] [Accepted: 09/10/2017] [Indexed: 11/18/2022]
Abstract
Objective This study was to identify whether working memory (WM) can be clearly subdivided according to auditory and visual modality. To do this, we administered the most recent and universal clinical WM measures in a mixed psychiatric sample. Methods A total of 115 patients were diagnosed on the basis of DSM-IV diagnostic criteria and with MINI-Plus 5.0, a structured diagnostic interview. WM subtests of Korean version of Wechsler Adult Intelligence Scale-IV and Korean version of Wechsler Memory Scale-IV were administered to assess WM. Confirmatory factor analysis (CFA) was used to observe whether WM measures fit better to a one-factor or two-factor model. Results CFA results demonstrated that a two factor model fits the data better than one-factor model as expected. Conclusion Our study supports a modality model of WM, or the existence of modality-specific WM systems, and thus poses a clinical significance of assessing both auditory and visual WM tests.

Abstract
Objective This 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. Methods One 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. Results K-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). Conclusion The 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.

Abstract
Objective It is not easy to diagnose bipolar disorders accurately in the clinical setting. Although Korean version of the Mood Disorder Questionnaire (K-MDQ) is easily administered, it still has weakness regarding case finding. In this study, we suggest a new weighted version of the K-MDQ to increase its screening power. Methods Ninety-five patients with bipolar disorders and 346 controls (patients with schizophrenia, patients with depressive disorders, patients with anxiety disorders, and subjects without any psychiatric disease) were enrolled in this study. The subjects received brief information on the K-MDQ, and then independently completed the questionnaire. Results Using odds ratios, we constructed a new weighted K-MDQ (W-K-MDQ). Item 1 (feel so good or hyper) was weighted 7 times and item 4 (less sleep) 3.5 times. Item 7 (easily distracted) and item 11 (more interested in sex) were excluded. Part 2 (simultaneity) and 3 (functional impairment) were also excluded as in the original K-MDQ. The sensitivity of the W-K-MDQ with a cutoff value of 10 was enhanced to 0.789. The area under the receiver operating characteristic curve was increased to 0.837. Conclusion We suggested a new formula for K-MDQ using 11 of its items. The W-K-MDQ can be easily applied with good sensitivity to screen for bipolar disorders in clinical settings in Korea. Further evaluations with larger samples are needed to establish the usefulness of the W-K-MDQ.

Korean Medication Algorithm for Depressive Disorders 2017: Third Revision. CLINICAL PSYCHOPHARMACOLOGY AND NEUROSCIENCE : THE OFFICIAL SCIENTIFIC JOURNAL OF THE KOREAN COLLEGE OF NEUROPSYCHOPHARMACOLOGY 2018; 16:67-87. [PMID: 29397669 PMCID: PMC5810446 DOI: 10.9758/cpn.2018.16.1.67] [Citation(s) in RCA: 26] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/12/2017] [Accepted: 08/01/2017] [Indexed: 12/22/2022]
Abstract
OBJECTIVE In 2002, the Korean Society for Affective Disorders developed the guidelines for the treatment of major depressive disorder (MDD), and revised it in 2006 and 2012. The third revision of these guidelines was undertaken to reflect advances in the field. METHODS Using a 44-item questionnaire, an expert consensus was obtained on pharmacological treatment strategies for MDD 1) without or 2) with psychotic features, 3) depression subtypes, 4) maintenance, 5) special populations, 6) the choice of an antidepressant (AD) regarding safety and adverse effects, and 7) non-pharmacological biological therapies. Recommended first, second, and third-line strategies were derived statistically. RESULTS AD monotherapy is recommended as the first-line strategy for non-psychotic depression in adults, children/adolescents, elderly adults, patient with persistent depressive disorder, and pregnant women or patients with postpartum depression or premenstrual dysphoric disorder. The combination of AD and atypical antipsychotics (AAP) was recommended for psychotic depression in adult, child/adolescent, postpartum depression, and mixed features or anxious distress. Most experts recommended stopping the ongoing initial AD and AAP after a certain period in patients with one or two depressive episodes. As an MDD treatment modality, 92% of experts are considering electroconvulsive therapy and 46.8% are applying it clinically, while 86% of experts are considering repetitive transcranial magnetic stimulation but only 31.6% are applying it clinically. CONCLUSION The pharmacological treatment strategy in 2017 is similar to that of Korean Medication Algorithm for Depressive Disorder 2012. The preference of AAPs was more increased.

Abstract
Objective The aim of this study was to examine the validity of the Korean version of the Hypomania Checklist-32, second revision (HCL-32-R2) in mood disorder patients. Methods A total of 454 patients who diagnosed as mood disorder according to Structured Clinical Interview for DSM-IV Axis I Disorders, clinician version (SCID-CV) (bipolar disorder [BD] I, n=190; BD-II, n=72; and major depressive disorder [MDD], n=192) completed the Korean module of the HCL-32-R2 (KHCL-32-R2). Results The KHCL-32-R2 showed a three-factorial structure (eigenvalue >2) that accounted for 43.26% of the total variance. Factor 1 was labeled “active/elated” and included 16 items; factor 2, “irritable/distractible” and included 9 items; and factor 3 was labeled “risk-taking/indulging” and included 9 items. A score of 16 or more on the KHCL-32-R2 total scale score distinguished between BD and MDD, which yielded a sensitivity of 70% and a specificity of 70%. MDD and BD-II also could be differentiated at a cut-off of 15 with maximized sensitivity (0.67) and specificity (0.66). Cronbach’s alpha of KHCL-32-R2 and its subsets (factors 1, 2, and 3) were 0.91, 0.89, 0.81 and 0.79, respectively. Correlations between KHCL-32-R2 and Montgomery-Asberg Depression Rating Scale, Young Mania Rating Scale and Korean version of Mood Disorder Questionnaire were −0.66 (p=0.41), −0.14 (p=0.9), and 0.61 (p<0.001), respectively. Conclusion The KHCL-32-R2 may be a useful tool in distinguishing between bipolar and depressive patients in clinical settings.

Abstract
In this review, we compared recommendations from the Korean Medication Algorithm Project for Depressive Disorder 2017 (KMAP-DD 2017) to other global treatment guidelines for depression. Six global treatment guidelines were reviewed; among the six, 4 were evidence-based guidelines, 1 was an expert consensus-based guideline, and 1 was an amalgamation of both evidence and expert consensus-based recommendations. The recommendations in the KMAP-DD 2017 were generally similar to those in other global treatment guidelines, although there were some differences between the guidelines. The KMAP-DD 2017 appeared to reflect current changes in the psychopharmacology of depression quite well, like other recently published evidence-based guidelines. As an expert consensus-based guideline, the KMAP-DD 2017 had some limitations. However, considering there are situations in which clinical evidence cannot be drawn from planned clinical trials, the KMAP-DD 2017 may be helpful for Korean psychiatrists making decisions in the clinical settings by complementing previously published evidence-based guidelines.

Abstract
Objective Although aripiprazole has been widely used to treat various psychiatric disorders, little is known about the adequate dosage for Asian patients in clinical practice. Hence, we evaluated the initial and maximum doses of aripiprazole from 2004 to 2014 to estimate the appropriate dosage for Korean psychiatric inpatients in clinical practice. Methods In this retrospective study, we reviewed the medical records of patients who were hospitalized in five university hospitals in Korea from March 2004 to December 2014. The psychiatric diagnosis according to the text revision of the Diagnostic and Statistical Manual of Mental Disorders, 4th edition during index hospitalization and the initial and maximum doses of aripiprazole were evaluated. Results There were 74 patients in Wave 1 (2004–2006), 201 patients in Wave 2 (2007–2010), and 353 patients in Wave 3 (2011–2014). The initial doses of aripiprazole in all diagnostic groups were significantly lower in Wave 3 than in Wave 2. The maximum doses of aripiprazole in each diagnostic group were not significantly different among Waves 1, 2, and 3. Conclusion The relatively low initial doses of aripiprazole documented in our study may reflect a strategy by clinicians to minimize the side effects associated with aripiprazole use, such as akathisia.

Abstract
OBJECTIVES As South Korea has the highest incidence of completed suicides, the present study aimed to investigate the predictive power of the variables that have been associated with suicide attempts in Korean patients diagnosed with depression. METHODS Hundred participants were divided into two groups: suicide attempters (31%) and suicide non-attempters (69%). Participants with a history of more than one suicidal attempt were assigned to the suicide attempter group. A hierarchical logistic regression analysis was performed to determine the predictive strengths of the variables that were likely to be associated with suicide attempts. RESULTS After controlling for the effects of such variables as the severity of depressive symptoms, life stress events and impulsivity, the severity of past suicidal ideation was the most important predictive factor for discriminating suicide attempters from suicide non-attempters. The odds ratio for attempting suicide relative to not attempting suicide increased by a factor of 4.408 for each unit of increase in suicidal ideation. CONCLUSIONS The present study suggests that the most severe suicidal ideation throughout one's entire life should not be overlooked and may be a major predictor of the risk of suicide.

Abstract
We examined predictors of suicide attempts in clinically depressed adolescents in Korea and gender differences in suicidal behavior. In total, 106 adolescents diagnosed with depressive disorder were recruited in South Korea. We assessed various variables that might affect suicide attempts, and used a structured interview for the diagnosis of depression and comorbidities and to evaluate suicidality. Demographic and clinical characteristics of the subjects were compared between suicide attempt and non-suicide attempt groups and we examined significant predictors of suicide attempts. Gender differences in suicidal ideation and suicidal behavior were also analyzed. Among 106 depressed participants, 50 (47.2%) adolescents were classified in the suicide attempt group. Generally, the suicide attempt and non-suicide attempt group shared similar clinical characteristics. The suicide attempt group had more females, more major depressive disorder diagnoses, more depressive episodes, and higher suicidal ideation than the non-suicide attempt group. Suicidal ideation was the only significant predictor of suicidal attempt, regardless of gender. Higher suicidal ideation frequency scores and more non-suicidal self-injurious behaviors were shown in the female suicide attempt group than the male suicide attempt group. It is recommended that suicidal ideation be assessed regularly and managed rigorously to decrease suicide risks in depressive adolescents.

Abstract
This study describes the use of a smartphone application based on the Korean version of the Mood Disorder Questionnaire in screening for bipolar spectrum disorders in a large general population. All data were collected between May 2011 and July 2011. A total of 27,159 individuals participated in the survey, using a smartphone application. The prevalence of positive screening results for bipolar spectrum disorders among 27,159 participants using the smartphone Korean Mood Disorder Questionnaire application was 8.2 percent. These results are similar to traditional paper-based results. The Korean Mood Disorder Questionnaire positive group exhibited more frequent occurrences of previous psychiatric treatment than the group with negative results. In a logistic regression analysis involving subjects with past psychiatric history, age group significantly predicted Korean Mood Disorder Questionnaire results. The smartphone application may be a useful screening tool for bipolar spectrum disorders. This study included only individuals who actively participated, and thus, the possibility of a selection bias should be considered.

Abstract
OBJECTIVE The purpose of this study was to investigate the efficacy and tolerability of atypical antipsychotics (AAPs) with augmentation by blonanserin in schizophrenic patients. METHODS aA total of 100 patients with schizophrenia who were partially or completely unresponsive to treatment with an AAP were recruited in this 12-week, open-label, non-comparative, multicenter study. Blonanserin was added to their existing AAP regimen, which was maintained during the study period. Efficacy was primarily evaluated using the Positive and Negative Syndrome Scale (PANSS) at baseline and at weeks 2, 4, 8, and 12. Predictors for PANSS response (≥20% reduction) were investigated. RESULTS The PANSS total score was significantly decreased at 12 weeks of blonanserin augmentation (-21.0±18.1, F=105.849, p<0.001). Moreover, 51.0% of participants experienced a response at week 12. Premature discontinuation of blonanserin occurred in 17 patients (17.0%); 4 of these patients dropped out due to adverse events. The patients who benefited the most from blonanserin were those with severe symptoms despite a treatment with a higher dose of AAP. CONCLUSION Blonanserin augmentation could be an effective strategy for patients with schizophrenia who were partially or completely unresponsive to treatment with an AAP.

The Protective Role of Resilience in Attenuating Emotional Distress and Aggression Associated with Early-life Stress in Young Enlisted Military Service Candidates. J Korean Med Sci 2015; 30:1667-74. [PMID: 26539013 PMCID: PMC4630485 DOI: 10.3346/jkms.2015.30.11.1667] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/22/2015] [Accepted: 08/11/2015] [Indexed: 11/20/2022] Open
Abstract
Early life stress (ELS) may induce long-lasting psychological complications in adulthood. The protective role of resilience against the development of psychopathology is also important. The purpose of this study was to investigate the relationships among ELS, resilience, depression, anxiety, and aggression in young adults. Four hundred sixty-one army inductees gave written informed consent and participated in this study. We assessed psychopathology using the Korea Military Personality Test, ELS using the Childhood Abuse Experience Scale, and resilience with the resilience scale. Analyses of variance, correlation analyses, and hierarchical multiple linear regression analyses were conducted for statistical analyses. The regression model explained 35.8%, 41.0%, and 23.3% of the total variance in the depression, anxiety, and aggression indices, respectively. We can find that even though ELS experience is positively associated with depression, anxiety, and aggression, resilience may have significant attenuating effect against the ELS effect on severity of these psychopathologies. Emotion regulation showed the most beneficial effect among resilience factors on reducing severity of psychopathologies. To improve mental health for young adults, ELS assessment and resilience enhancement program should be considered.

The Korean Medication Algorithm for Depressive Disorder: second revision. J Affect Disord 2015; 167:312-21. [PMID: 25010375 DOI: 10.1016/j.jad.2014.05.031] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/20/2013] [Revised: 05/19/2014] [Accepted: 05/20/2014] [Indexed: 12/27/2022]
Abstract
AIM This study constitutes a revision of the guidelines for the treatment of major depressive disorder (MDD) issued by the Korean Medication Algorithm Project for Depressive Disorder (KMAP-DD) 2006. In incorporates changes in the experts׳ consensus that occurred between 2006 and 2012 as well as information regarding newly developed and recently published clinical trials. METHODS Using a 44-item questionnaire, an expert consensus was obtained on pharmacological treatment strategies for (1) non-psychotic MDD, (2) psychotic MDD, (3) dysthymia and depression subtypes, (4) continuous and maintenance treatment, and (5) special populations; consensus was also obtained regarding (6) the choice of an antidepressant (AD) in the context of safety and adverse effects, and (7) non-pharmacological biological therapies. RESULTS AD monotherapy was recommended as the first-line strategy for nonpsychotic depression in adults, children and adolescents, elderly adults, and patients with postpartum depression or premenstrual dysphoric disorder. The combination of AD and atypical antipsychotics (AAP) was recommended for psychotic depression. The duration of the initial AD treatment for psychotic depression depends on the number of depressive episodes. Most experts recommended stopping the initial AD and AAP therapy after a certain period in patients with one or two depressive episodes. However, for those with three or more episodes, maintenance of the initial treatment was recommended for as long as possible. Monotherapy with various selective serotonin reuptake inhibitors (SSRIs) and serotonin and norepinephrine reuptake inhibitors (SNRIs) was recommended for dysthymic disorder and melancholic type MDD. CONCLUSION The pharmacological treatment strategy of KMAP-DD 2012 is similar to that of KMAP-DD 2006; however, the preference for the first-line use of AAPs was stronger in 2012 than in 2006.

Abstract
Our goal was to compare the recommendations of the Korean Medication Algorithm Project for Bipolar Disorder 2014 (KMAP-BP 2014) with other recently published guidelines for the treatment of bipolar disorder. We reviewed a total of four recently published global treatment guidelines and compared each treatment recommendation of the KMAP-BP 2014 with those in other guidelines. For the initial treatment of mania, there were no significant differences across treatment guidelines. All recommended mood stabilizer (MS) or atypical antipsychotic (AAP) monotherapy or the combination of an MS with an AAP as a first-line treatment strategy for mania. However, the KMAP-BP 2014 did not prefer monotherapy with MS or AAP for dysphoric/psychotic mania. Aripiprazole, olanzapine, quetiapine, and risperidone were the first-line AAPs in nearly all of the phases of bipolar disorder across the guidelines. Most guidelines advocated newer AAPs as first-line treatment options in all phases, and lamotrigine in depressive and maintenance phases. Lithium and valproic acid were commonly used as MSs in all phases of bipolar disorder. As research evidence accumulated over time, recommendations of newer AAPs - such as asenapine, paliperidone, lurasidone, and long-acting injectable risperidone - became prominent. This comparison identifies that the treatment recommendations of the KMAP-BP 2014 are similar to those of other treatment guidelines and reflect current changes in prescription patterns for bipolar disorder based on accumulated research data. Further studies are needed to address several issues identified in our review.

Abstract
OBJECTIVE To constitute the third revision of the guidelines for the treatment of bipolar disorder issued by the Korean Medication Algorithm Project for Bipolar Disorder (KMAP-BP 2014). METHODS A 56-item questionnaire was used to obtain the consensus of experts regarding pharmacological treatment strategies for the various phases of bipolar disorder and for special populations. The review committee included 110 Korean psychiatrists and 38 experts for child and adolescent psychiatry. Of the committee members, 64 general psychiatrists and 23 child and adolescent psychiatrists responded to the survey. RESULTS The treatment of choice (TOC) for euphoric, mixed, and psychotic mania was the combination of a mood stabilizer (MS) and an atypical antipsychotic (AAP); the TOC for acute mild depression was monotherapy with MS or AAP; and the TOC for moderate or severe depression was MS plus AAP/antidepressant. The first-line maintenance treatment following mania or depression was MS monotherapy or MS plus AAP; the first-line treatment after mania was AAP monotherapy; and the first-line treatment after depression was lamotrigine (LTG) monotherapy, LTG plus MS/AAP, or MS plus AAP plus LTG. The first-line treatment strategy for mania in children and adolescents was MS plus AAP or AAP monotherapy. For geriatric bipolar patients, the TOC for mania was AAP/MS monotherapy, and the TOC for depression was AAP plus MS or AAP monotherapy. CONCLUSION The expert consensus in the KMAP-BP 2014 differed from that in previous publications; most notably, the preference for AAP was increased in the treatment of acute mania, depression, and maintenance treatment. There was increased expert preference for the use of AAP and LTG. The major limitation of the present study is that it was based on the consensus of Korean experts rather than on experimental evidence.

Abstract
INTRODUCTION The objective of the current study was to assess, in a naturalistic treatment setting, the clinical benefits of lamotrigine add-on therapy for patients with bipolar disorder. METHODS This was an open-label, prospective, naturalistic, 12-week, observational study that included 98 bipolar patients treated with lamotrigine add-on therapy, in addition to mood stabilizers or atypical antipsychotics for 1-4 weeks. The clinical benefits of lamotrigine augmentation were evaluated using the Clinical Global Impression-Clinical Benefit (CGI-CB) Scale, and the Clinical Global Impression of Bipolar Disorder-Severity scale was used to evaluate the severity of the patients' conditions. RESULTS According to paired t-test analyses, the mean CGI-CB score significantly decreased from 7.2 ± 2.7 at baseline to 3.8 ± 2.5 at Week 12. Likewise, the mean score for Clinical Global Impression of Bipolar Disorder-Severity scale significantly decreased from 4.7 ± 0.9 at baseline to 3.1 ± 1.2 at Week 12. Analysis of covariance showed that the extent to which CGI-CB scores changed from baseline to Week 12 did not significantly differ between patients with bipolar I and II disorder. However, the change in CGI-CB scores between Weeks 4 and 12 was significantly smaller in bipolar II patients than bipolar I patients. A total of 21 (21.4%) patients dropped out during the course of the study, and 30 patients (30.6%) reported 82 adverse events. DISCUSSION The results of this study demonstrated that the use of lamotrigine in patients with bipolar disorder, especially those whom conventional mood stabilizers or antipsychotics are insufficiently effective or intolerable, can be beneficial regardless of the type of bipolar disorder.

Is it useful to use the Korean version of the mood disorder questionnaire for assessing bipolar spectrum disorder among Korean college students? Asia Pac Psychiatry 2014; 6:170-8. [PMID: 23857742 DOI: 10.1111/appy.12026] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/22/2012] [Accepted: 11/18/2012] [Indexed: 01/08/2023]
Abstract
INTRODUCTION The purpose of this study was to assess the usefulness of the Korean version of the Mood Disorder Questionnaire (K-MDQ) as a screening tool for the identification of bipolar spectrum disorder (BSD) among Korean college students. METHODS The sample of 1,020 college students was stratified to reflect geographical differences among the students. The K-MDQ and an epidemiological survey were administered between November 2006 and February 2007. To validate the K-MDQ as a screening tool for BSD, the Korean version of the Bipolar Spectrum Diagnostic Scale (K-BSDS) and the Structured Clinical Interview for DSM-IV (SCID) were also administered. RESULTS The rates satisfying MDQ criterion 1, and all three MDQ criteria, were 55.5% and 2.3%, respectively. According to the K-BSDS, 59.9% of the sample met the criteria for BSD using a threshold of 10, while no statistical differences were observed among subgroups. When we examined the diagnostic agreement between K-MDQ and K-BSDS, 79.5% of students who met MDQ criterion 1 were also positive on the BSDS. Sixteen (21.6%) of the 74 students who participated in the SCID interview were diagnosed with BSD. DISCUSSION Although the K-MDQ is a useful tool to assess BSD among inpatients and outpatients, it does not appear useful as a screening tool to detect BSD among college students.

Characteristics of bipolar symptoms in psychiatric patients: pattern of responses to the Korean version of the Mood Disorder Questionnaire. Asia Pac Psychiatry 2014; 6:120-6. [PMID: 23857745 DOI: 10.1111/j.1758-5872.2012.00224.x] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/15/2012] [Accepted: 06/07/2012] [Indexed: 11/30/2022]
Abstract
INTRODUCTION Bipolar disorders are relatively frequent but easily misdiagnosed. The Korean version of the Mood Disorder Questionnaire (K-MDQ) is a screening instrument for bipolar disorders. The aim of this study was to establish the pattern of responses to the K-MDQ for several psychiatric disorders. METHODS The subjects for this study were 345 patients with bipolar disorders, schizophrenia, depressive disorders or anxiety disorders, as determined using the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision, and 96 controls from five hospitals. The subjects completed the questionnaire by themselves. RESULTS The total K-MDQ score was higher in the bipolar disorder group than the other groups. Although the mean K-MDQ score differed significantly between the bipolar disorder group and the other groups, the distributions of total scores for the groups overlapped, and in particular with the schizophrenia group. The area under the receiver operating characteristics curve was relatively high for the bipolar disorder group and the other subjects, but it was less than 0.8 between the bipolar disorder group, and the schizophrenia and control groups. DISCUSSION There are some distinguishing features of the K-MDQ pattern for each disorder, but their similarities were significant. This made it difficult to differentially diagnose the disorder using only the total K-MDQ score. The diagnostic power of the K-MDQ can only be improved in the clinical setting by utilizing reinforcing criteria to diagnose bipolar disorders. Clinicians should be cautious in their interpretation of the K-MDQ, and the use of additional data is essential.

One-year rehospitalization rates of patients with first-episode bipolar mania receiving lithium or valproate and adjunctive atypical antipsychotics. Psychiatry Clin Neurosci 2014; 68:418-24. [PMID: 24506520 DOI: 10.1111/pcn.12145] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/10/2013] [Revised: 11/05/2013] [Accepted: 12/04/2013] [Indexed: 12/26/2022]
Abstract
AIM We compared the 1-year rehospitalization rates of first-episode bipolar manic patients who were discharged while being treated with lithium or valproate in combination with an atypical antipsychotic. METHODS We investigated the rehospitalization status of first-episode bipolar manic patients who were discharged between 1 January 2003 and 31 December 2010 while they were taking lithium or valproate in combination with aripiprazole, olanzapine, quetiapine, or risperidone. Rehospitalization rates during a 1-year period after discharge were compared between the group receiving lithium plus an atypical antipsychotic and the group receiving valproate plus an atypical antipsychotic using the Kaplan-Meier method. A Cox regression model was used to analyze covariates hypothesized to affect time to rehospitalization. RESULTS The rehospitalization rate was 17.3% during the 1-year follow-up period. We found significant differences in the rehospitalization rates of patients in the lithium (23.1%) and the valproate (13.3%) groups using the Kaplan-Meier formula. According to Cox proportional hazards regression analysis, higher Clinical Global Impression-Bipolar Version-Severity score at discharge (P = 0.005) and lithium treatment (P = 0.055) contributed to the risk of rehospitalization. CONCLUSION Treatment with valproate and an atypical antipsychotic can be more effective than treatment with lithium and an atypical antipsychotic in preventing rehospitalization during the 1 year after hospitalization due to a first manic episode in patients with bipolar I disorder. Higher Clinical Global Impression-Bipolar Version-Severity scores at discharge also negatively affected rehospitalization rates.

Abstract
We aimed to compare the recommendations of the Korean Medication Algorithm Project for Depressive Disorder 2012 (KMAP-DD 2012) with other recently published treatment guidelines for depressive disorder. We reviewed a total of five recently published global treatment guidelines and compared each treatment recommendation of the KMAP-DD 2012 with those in other guidelines. For initial treatment recommendations, there were no significant major differences across guidelines. However, in the case of nonresponse or incomplete response to initial treatment, the second recommended treatment step varied across guidelines. For maintenance therapy, medication dose and duration differed among treatment guidelines. Further, there were several discrepancies in the recommendations for each subtype of depressive disorder across guidelines. For treatment in special populations, there were no significant differences in overall recommendations. This comparison identifies that, by and large, the treatment recommendations of the KMAP-DD 2012 are similar to those of other treatment guidelines and reflect current changes in prescription pattern for depression based on accumulated research data. Further studies will be needed to address several issues identified in our review.

Abstract
INTRODUCTION The Feasibility Study of the Korean Medication Algorithm Project for Bipolar Disorder 2002 (KMAP-BP 2002) revealed its clinical usefulness in 2005. Since much more data had become available since 2002, it was revised in 2006 as KMAP-BP 2006. For the same reason, revision of KMAP-BP 2006 is now necessary. METHODS The questionnaire, amended on the basis of KMAP-BP 2006 and new data, was sent to 94 experts, 65 of whom replied. RESULTS In an acute manic episode, a combination of a mood stabilizer (MS) with an atypical antipsychotic (AAP) is recommended as first-line strategy. Monotherapy with MS is first-line in a hypomanic episode. Triple combination of a MS, an AAP, and an antidepressant (AD), is the first-line strategy in non-psychotic severe depression. Also MS+AAP and MS+AD are recommended as first-line. In psychotic bipolar depression, MS+AAP+AD, MS+AAP and AAP+AD are first-line strategies. In bipolar depression, lithium, lamotrigine and valproic acid are selected as first-line MS and quetiapine, olanzapine and aripiprazole are preferred antipsychotics. In maintenance treatment, a combination of MS with AAP and monotherapy of MS are recommended as first-line. DISCUSSION In treating bipolar disorder, even the first step of treatment, the expert consensus has changed from our studies in 2002 and 2006.

Abstract
PURPOSE To evaluate and compare the therapeutic efficacy of quetiapine in bipolar I and II depression patients in the clinical setting. PATIENTS AND METHODS This was an 8-week, multicenter, open-label, observational study for bipolar depression. The dosage of quetiapine was flexible, and concomitant medications were permitted on clinician's judgments. A total of 1097 patients were enrolled, and 764 bipolar depression patients who exhibited good therapeutic compliance (>75% compliance rate) were analyzed. RESULTS Clinical Global Impression - Bipolar scale and Montgomery-Asberg Depression Rating Scale scores were significantly improved at weeks four and eight compared with the baseline scores. At the end of the 8-week study, the response rate was 58.9%, and the remission rate was 42.1%. However, there were no significant differences in the response and remission rates between bipolar I and II disorder (BD-I and BD-II) patients (response rate 60.1% versus 56.3%; remission rate 44.5% versus 37.0%). Montgomery-Asberg Depression Rating Scale score at baseline (β = 0.612, P < 0.001), duration of current episode (β = -0.152, P = 0.001), and presence of remission on previous episode (β = 0.111, P = 0.012) were significantly associated with improvements in depressive symptoms. Fatigue (16.0%), somnolence (14.9%), and manic/hypomanic switching (0.6% at week four, 0.3% at week eight) were observed throughout the study period. CONCLUSION The results of this study suggest that quetiapine improves depressive symptoms in BD-I and BD-II patients with a minimal incidence of manic switching. The therapeutic efficacy of quetiapine increased with time. Quetiapine could be an effective and safe modality for the treatment of BD-I and BD-II.

Abstract
BACKGROUND The purpose of this study was to assess the prevalence of bipolar spectrum disorder (BSD) in the general Korean population. METHODS A sample of college students (n = 1026) was stratified to reflect geographical differences accurately in Korean college students. The Korean version of the Mood Disorder Questionnaire (K-MDQ) was administered and an epidemiological survey carried out between November 2006 and February 2007. BSD was defined as a score of at least seven K-MDQ symptoms that co-occurred and resulted in minimal or more functional impairment. RESULTS The prevalence of BSD was 18.6% (95% confidence interval [CI] 16.2-21.0) in total, being 19.8% (95% CI 16.3-23.2) in men and 17.5% (95% CI 14.2-20.8) in women. The prevalence of BSD was more common in rural dwellers than in urban dwellers (P = 0.008, chi-square test). Univariate and multivariate regression models showed that rural residence was a significant factor associated with BSD. There were significant relationships between BSD and gender, age, and socioeconomic status. CONCLUSION The prevalence of BSD found in the present study is higher than that reported by other epidemiological studies in Korea and in international studies.

Abstract
Objective Brain-derived neurotrophic factor (BDNF) plays an important role in cell survival, differentiation, and cell death as well as in neural plasticity. Recent studies have suggested that BDNF is involved in the pathogenesis of bipolar disorder. The aim of this study was to investigate the association of the genetic variations of the BDNF gene with bipolar disorder in Korea. We also studied the possible association of these genetic variants with clinical features. Methods The allelic and genotypic distributions of Val66Met polymorphism of the BDNF gene were analyzed using a polymerase chain reaction-based method in 184 bipolar patients and 214 controls. Analysis was performed to investigate an association of the Val66Met polymorphism of the BDNF gene and the clinical features in bipolar patients. Results No significant difference was found between bipolar patients and controls in the genotype and allele frequencies for the investigated BDNF polymorphism. However, the age of onset of bipolar disorder among the Val/Val (25.57), Val/Met (30.42) and Met/Met (32.45) genotype groups were significantly different (p=0.037). Conclusion This study suggests that Val66Met polymorphisms are unlikely to contribution to the genetic predisposition to bipolar disorder as a whole. But Val66Met polymorphism may be associated with age of onset of the disorder, further studies designed to investigate the relationship in a larger population may be warranted.

Abstract
OBJECTIVE This study explored the clinical characteristics and risk factors of suicidal ideation in a sample of first graders from South Korea. Children's depression and aggression and maternal depression were examined as possible risk factors. METHODS This study is a school-based, cross-sectional study of 5 elementary schools in Gunpo City, South Korea. Participants were 707 first graders (mean age, 6.54 years) and their mothers. We assessed children's depressive and aggressive symptoms using the Behavior Assessment System for Children-2 (BASC-2) and maternal depression using the Beck Depression Inventory (BDI). Two items from BASC-2 and 1 item from BDI identified children's and maternal suicidal ideation. RESULTS Twenty-seven (3.8%) children evidenced suicidal ideation. Children with suicidal ideation had higher mean scores of depression domain (10.11 ± 5.34 vs 4.57 ± 3.44, P < .0001) and aggression domain (7.78 ± 3.84 vs 3.80 ± 2.85, P < .0001) on BASC-2 and maternal depression (9.78 ± 6.45 vs 7.28 ± 5.38, P = .02) on BDI. In regression analysis, children's depression (odds ratio [OR], 1.19; 95% confidence interval [CI], 1.07-1.32; P = .001) and aggression (OR, 1.24; 95% CI, 1.08-1.41; P = .002) contributed significantly to children's suicidal ideation, whereas maternal depression was not significantly related to children's suicidal ideation (OR, 0.99; 95% CI, 0.92-1.06; P = .75). CONCLUSIONS This study demonstrated that even first graders had a considerable prevalence of suicidal ideation and that depression and aggression were associated with suicidal ideation in young children.

[PMID: 21329990 DOI: 10.1016/j.psychres.2011.01.009] [Citation(s) in RCA: 29] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/28/2010] [Revised: 12/27/2010] [Accepted: 01/11/2011] [Indexed: 10/18/2022]
Abstract
We examined the prevalence of painful physical symptoms in patients with major depressive disorder (MDD), clinical correlations therewith, and associations between painful symptoms and depression severity, quality of life, and suicidality, in a clinical sample in Korea. A total of 414 psychiatric outpatients at least 18years of age, with a primary diagnosis of MDD based on the DSM-IV-TR, were enrolled at the discretion of their treating psychiatrist. Patients were assessed for the presence or absence of painful physical symptoms (PPS+ and PPS-, respectively), defined by a total score ≥5 on the pain subscale (PS) of the Depression and Somatic Symptoms Scale (DSSS). DSSS and the Clinical Global Impressions-Severity of Illness scale (CGI-S) determined depression severity, and the EuroQoL Questionnaire-5 dimensions (EQ-5D) determined perceived quality of life. Questions about suicidality during current depressive episode were also asked to the participants. Overall, 30.4% of patients were classified as PPS+. PPS+ patients were older, less educated, less frequently unmarried, and more frequently widowed/divorced/separated compared to PPS- patients. PPS+ patients showed a significantly greater depression severity (CGI-S mean difference 0.92; 95% CI=0.68 to 1.16; DSSS mean difference 18.39; 95% CI=16.28 to 20.50), a significantly lower quality of life (EQ-5D VAS mean difference -18.15; 95% CI=-22.68 to -13.62), and significantly higher suicidal ideation (OR 1.73; 95% CI 1.04-2.86) during the current depressive episode. This study suggests that assessment of depressive patients should include detailed questions about painful physical symptoms, and treatment of MDD should involve management targeting painful physical symptoms as well as emotional and non-painful physical symptoms.

Effect of initial ziprasidone dose on treatment outcome of korean patients with acute manic or mixed episodes. Psychiatry Investig 2011; 8:207-13. [PMID: 21994507 PMCID: PMC3182385 DOI: 10.4306/pi.2011.8.3.207] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/19/2011] [Revised: 03/22/2011] [Accepted: 04/23/2011] [Indexed: 11/19/2022] Open
Abstract
OBJECTIVE We investigated the efficacy and tolerability of ziprasidone combined with divalproex to determine the relationship between the initial dose of ziprasidone and the treatment effect among Korean patients with acute bipolar manic or mixed disorders. METHODS This study was a 6-week, open-label, prospective investigation of Korean patients with an acute manic or mixed episode of bipolar disorder. Sixty-five patients were recruited. The patients were categorized based on the initial dose of ziprasidone as follows: low (20-79 mg/day) and standard (80 mg/day). Ziprasidone was given in combination with divalproex in flexible doses, according to the clinical response and tolerability. RESULTS The response and remission rates were significantly higher in the standard-dose group than the low-dose group. The combination of ziprasidone and divalproex was well-tolerated and adverse events were mostly mild with no statistically significant increase in body weight. CONCLUSION The results of this study showed that a standard starting dose of ziprasidone in combination with divalproex for bipolar disorder is more effective than a low starting dose.

Mental health and extracurricular education in Korean first graders: a school-based cross-sectional study. J Clin Psychiatry 2011; 72:861-8. [PMID: 21367346 DOI: 10.4088/jcp.09m05907gry] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/12/2009] [Accepted: 06/14/2010] [Indexed: 10/18/2022]
Abstract
OBJECTIVE This study explores the results of mental health screening in Korean first graders in association with the amount of time the children spent in extracurricular education. METHOD The study included a community sample of 761 boys and girls, with a mean age of 6.6 years, collected from 5 elementary schools in Gunpo-si, South Korea, in July 2007. Primary caregivers completed a questionnaire that included information on demographic characteristics, the amount of time the children spent in extracurricular education and other activities, and an adapted form of the Behavior Assessment System for Children, Second Edition (BASC-2) to screen for mental health problems. RESULTS These first graders spent a mean of a little over 2 hours each day in extracurricular education. Extracurricular education demonstrated positive correlations with 4 BASC-2 domains, including hyperactivity (r = 0.092, P < .05), aggression (r = 0.073, P < .05), conduct problems (r = 0.073, P < .05) and depression (r = 0.137, P < .01). A positive linear relationship between depression and extracurricular education was also evident in regression analyses (F = 2.25, R(2) = 0.022, P = .001). The relationship held true even when controlling for time spent with parents, time spent with friends, and time spent asleep. Post hoc analyses revealed that children receiving more than 4 hours of extracurricular education per day showed a sharp increase in depressive symptoms as well as a decrease in the amount of time spent with caregivers. CONCLUSIONS Results of this study demonstrate that excessive amounts of time spent in extracurricular education (greater than 4 hours per day) may be associated with depression in school-aged children. These findings have relevance for mental health screening and educational policy.
