Efficacy of Learning Disorder Treatment for Reading or Mathematics Disorders: An Open Study.

Objectives: This study aimed to identify the effectiveness of treatment programs for children with reading (RD) or mathematics disorders (MD). Structured treatment programs were developed to improve phonological awareness and number sense among children and adolescents with RD or MD, respectively, and the effectiveness of the learning disorder treatment programs were evaluated.

Methods: We used standardized, objective diagnostic, and evaluation tools not only to recruit participants with RD, MD, or comorbid attention deficit and hyperactivity disorder, but also to assess the effectiveness of the treatments regarding both improved core neurocognitive deficits of RD or MD and academic achievement.

Beyond Attention-Deficit Hyperactivity Disorder: Exploring Psychiatric Comorbidities and Their Neuropsychological Consequences in Adults.

Objectives: This study aimed to identify the psychiatric comorbidity status of adult patients diagnosed with attention-deficit hyperactivity disorder (ADHD) and determine the impact of comorbidities on neuropsychological outcomes in ADHD.

Methods: The study participants were 124 adult patients with ADHD. Clinical psychiatric assessments were performed by two boardcertified psychiatrists in accordance with the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition.

Cognitive Developmental Trajectories in Adult ADHD Patients and Controls: A Comparative Study.

Objective: There is an updated conceptualization of whole-lifespan attention-deficit hyperactivity disorder (ADHD), promoted by awareness of probable persistence of impairment into adulthood. We investigated cognition trajectories from adolescence to mid-adulthood in ADHD.

Method: Data of 240 patients with ADHD and 244 healthy controls (HCs) were obtained; clinical symptoms and neuropsychological functions were assessed using the various tests.

Validity of the Korean Version of DIVA-5: A Semi-Structured Diagnostic Interview for Adult ADHD.

Background: This study was to assess the validity of the Korean version of the semi-structured Diagnostic Interview for Adult ADHD, third edition (DIVA-5). The secondary aim was to compare sociodemographic and psychiatric comorbidities in adult patients with and without a diagnosis of ADHD.

Methods: A total of 279 participants were recruited from nine psychiatric outpatient clinics in Korea.

Development of the Korean Practice Parameter for Adult Attention-Deficit/Hyperactivity Disorder.

Objectives: Adult attention-deficit/hyperactivity disorder (ADHD) is an important mental health problem that needs resolution, especially considering the high rates of ADHD continuation from childhood to adolescence/adulthood and the high prevalence of ADHD in adults. Adults with ADHD have lifelong negative impacts and require close monitoring with long-term follow-up. Hence, the establishment of a Korean practice parameter for adult ADHD is necessary to minimize discontinuation of treatment and enable information sharing among Korean mental health professionals.

Comparison of Attention-Deficit/Hyperactivity Disorder Practice in Adults According to a Training Background in Child Psychiatry.

Objectives: Awareness of attention-deficit/hyperactivity disorder (ADHD) in adults has significantly increased; however, clinical data specific to the Korean population are insufficient. Clinical experience of ADHD may differ based on whether psychiatrists have received pediatric psychiatry-specific training. In order to prepare a practice parameter for adult ADHD patients in Korea, we examined questionnaire data to observe how pediatric psychiatry training could affect clinical practice for adults with ADHD.

Clinical Utility and Cut-Off Scores of the Korean Adult Attention-Deficit/Hyperactivity Disorder Rating Scale.

Objectives: This study was conducted to re-validate the clinical efficacy of the Korean Adult Attention-Deficit/Hyperactivity Disorder (ADHD) Rating Scale (K-AARS), which is a self-report scale for ADHD in adults, and to determine the clinical utility and cut-off scores of K-AARS.

Methods: The participants were 135 drug naïve adults with ADHD and 144 healthy controls. To diagnose ADHD based on the diagnostic criteria of the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition, two board-certified pediatric psychiatrists interviewed the participants and completed the Mini International Neuropsychiatric Interview.

Developmental Trajectories of Attention in Normal Korean Population.

Objectives: This study aimed to investigate the trajectory of change of diverse attention and working memory in Koreans from 4 to 40 years of age.

Methods: The data of 912 subjects from 4 to 15 years of age obtained from a previous standardization study of the computerized comprehensive attention test were merged with the newly obtained data of 150 subjects aged 16 to 40 years from this study. We evaluated the various kinds of attention, in which each subtest had five indicators.

Cross Validation of Attention-Deficit/Hyperactivity Disorder-After School Checklist.

Objectives: This study aimed to evaluate the efficacy of the attention-deficit/hyperactivity disorder (ADHD)-After School Checklist (ASK) by comparing the results of the Comprehensive Attention Test (CAT) and Clinical Global Impression-Severity (CGI-S) Scale and then by calculating the area under the receiver operating characteristic (ROC) curve.

Methods: We performed correlation analyses on the ASK and CAT results and then the ASK and CGI-S results. We created a ROC curve and evaluated performance on the ASK as a diagnostic tool.

Development of the Attention-Deficit Hyperactivity Disorder-After School Checklist.

Objectives: This study aimed to develop the attention-deficit hyperactivity disorder (ADHD)-After School Checklist (ASK) to evaluate the severity of ADHD symptoms and self-management ability in children and adolescents in South Korea. Additionally, we evaluated the reliability and validity of the scale.

Methods: We developed the ASK to evaluate the effect of ADHD psychopathologies on self-management and interpersonal impulsivity.

A multicenter, randomized, double-blind, placebo-controlled study of aripiprazole in children and adolescents with Tourette's disorder.

Objective: To examine the short-term efficacy and tolerability of aripiprazole for children and adolescents with Tourette's disorder.

Method: This 10-week multicenter, double-blind, randomized, placebo-controlled trial was conducted from August 2008 to April 2010. Children and adolescents (aged 6-18 years) with a DSM-IV diagnosis of Tourette's disorder and a Yale Global Tic Severity Scale total tic score of 22 or more were randomly assigned (1:1 ratio) to placebo or aripiprazole.
