Psychometrics of rating scales for externalizing disorders in Japanese outpatients: The ADHD-Rating Scale-5 and the Disruptive Behavior Disorders Rating Scale.

Objectives: This study validated the Japanese version of the Attention-Deficit/Hyperactivity Disorder-Rating Scale-5 (ADHD-RS-5) and the Disruptive Behavior Disorders Rating Scale. We extended the ADHD-RS-5 by adding the oppositional defiant disorder and conduct disorder subscales to compare the two rating scales psychometrically.

Methods: We examined the internal consistency, test-retest reliability, construct validity and criterion validity of the two rating scales in 135 Japanese outpatients aged 6-18 years.

Validity and reliability of the Japanese versions of the coronavirus anxiety scale for adolescents and obsession with COVID-19 scale for adolescents.

Background: The coronavirus disease 2019 (COVID-19) has caused mental health issues in both adults and adolescents. The Coronavirus Anxiety Scale (CAS) and Obsession with COVID-19 Scale (OCS) questionnaires measure anxiety and persistent and disturbed thoughts (also known as obsessions) related to COVID-19. We developed Japanese versions of the CAS (, CAS-JA) and OCS (, OCS-JA) questionnaires to make them suitable for adolescents and validated the characteristics of these scales.

Psychometrics of the kiddie schedule for affective disorders and schizophrenia present and lifetime version for DSM-5 in Japanese outpatients.

Objective: The Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime version (K-SADS-PL) is a widely used semi-structured diagnostic interview in child and adolescent psychiatry. However, the psychometric properties of its updated version, the K-SADS-PL for DSM-5, have scarcely been examined, especially for criterion validity. This study was designed to examine the inter-rater reliability, criterion validity and construct validity of the K-SADS-PL for DSM-5 in 137 Japanese outpatients.

Guided internet-based cognitive behavioral therapy for obsessive-compulsive disorder: A multicenter randomized controlled trial in Japan.

Unlabelled: Few studies have compared the effectiveness of internet-based cognitive behavior therapy (ICBT) for obsessive-compulsive disorder (OCD) with treatment as usual (TAU). We investigated the effectiveness of guided ICBT for patients with OCD. This prospective, randomized, controlled, assessor-blinded, multicenter clinical trial was conducted at three facilities in Japan from January 2020 to March 2021.

Practical applications of brief screening questionnaires for autism spectrum disorder in a psychiatry outpatient setting.

Objectives: This study was designed to examine the diagnostic performance of the social and communication disorders checklist (SCDC) and strength and difficulties questionnaire (SDQ) to detect autism spectrum conditions (ASC), along with the social responsiveness scale-second edition (SRS-2) as reference, in a psychiatry outpatient setting.

Methods: We translated the SCDC into Japanese since its Japanese version was unavailable. We examined its test-retest reliability as well as the internal consistency reliability and diagnostic performance of the three questionnaires among 41 Japanese psychiatric outpatients, using the best-estimate diagnosis of ASC based on the diagnostic interview for social and communication disorders, as a gold standard.

Guided Internet-Based Cognitive Behavioral Therapy in Japanese Patients With Obsessive-Compulsive Disorder: Protocol for a Randomized Controlled Trial.

Background: Cognitive behavioral therapy for obsessive-compulsive disorder has been established, but access to this therapy in Japan is limited. Internet-based cognitive behavioral therapy may improve treatment accessibility and sufficiently improve obsessive-compulsive symptoms. There are few randomized controlled trials examining the effectiveness of internet-based cognitive behavioral therapy in patients with obsessive-compulsive disorder.

The Kiddie Schedule for Affective Disorders and Schizophrenia Present and Lifetime Version (K-SADS-PL) for DSM-5: A validation for neurodevelopmental disorders in Japanese outpatients.

Objective: The Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime version (K-SADS-PL) is a widely used semi-structured diagnostic interview in child and adolescent psychiatry. However, given the extensive use of the K-SADS-PL in clinical practice and research and its adaptation for use in many languages and cultures, validation studies of the instrument are scarce. This study was designed to examine the inter-rater reliability, criterion validity and construct validity of the updated instrument, the K-SADS-PL for DSM-5, in Japanese outpatients totaling 95 children and adolescents.

Generalized social anxiety disorder: A still-neglected anxiety disorder 3 decades since Liebowitz's review.

In the 3 decades since Liebowitz's review of 'a neglected anxiety disorder,' controversy and challenges have remained in the study of social anxiety disorder (SAD). This review examines evidence around the classification and subtyping of SAD, focusing on generalized SAD. Substantial discrepancies and variation in definition, epidemiology, assessment, and treatment of generalized SAD exist as the international literature on it has grown.

Long-term outcome and preprocedural predictors of atrial tachyarrhythmia recurrence following pulmonary vein antrum isolation-based catheter ablation in patients with non-paroxysmal atrial fibrillation.

Background: Although various empiric adjunctive ablation techniques are widely performed with pulmonary vein antrum isolation (PVAI) to enhance the procedural efficacy of catheter ablation in non-paroxysmal atrial fibrillation (NPAF) patients, they are not required in all NPAF patients.

Methods And Results: Eighty consecutive NPAF patients refractory to antiarrhythmic drugs underwent a PVAI-based ablation. Structural heart disease was present in 40% of patients and systolic dysfunction in 21%.

Time-dependent variation in coronary flow velocity reserve induced by adenosine triphosphate: comparison to low-dose dipyridamole.

Background: Measuring the coronary flow velocity reserve (CFVR) by transthoracic Doppler echocardiography (TTDE) has been widely performed using adenosine. Although adenosine infusion is known to induce transient variation of hyperemia, the timing to measure the CFVR has not been well addressed. Therefore, we aimed to clarify the difference between the peak CFVR and at 2 min following adenosine triphosphate (ATP) infusion compared to the CFVR after low-dose dipyridamole infusion.

[The neurotic disorders].

The clinical practice of child and adolescent psychiatry includes encounters with disorders not particular to childhood and adolescence, but seen in adulthood as well. For example, among the neurotic disorders, obsessive-compulsive disorder can be seen from around 3 years of age, with rapid rise in prevalence from around age 10. Increase is also seen in cases of anorexia nervosa from around age 11.

Relationship of hypersensitivity to anxiety and depression in children with high-functioning pervasive developmental disorders.

Aims: Sensory-perceptual abnormalities, which include hyper- and hyposensitivity, have been identified by numerous researchers as prevalent in individuals with pervasive developmental disorders (PDD). Hypersensitivity has a greater impact on PDD patients' daily lives than hyposensitivity. The purpose of the present study was to clarify the relationship of hypersensitivity to anxiety, depression and other psychopathology in children with PDD.

Evaluation of attention-deficit/hyperactivity disorder symptoms in male children with high-functioning pervasive developmental disorders.

Background: Although there are many reports of high rates of hyperactivity and attention deficits in children with Pervasive Developmental Disorders (PDD), controversy remains about the applicability of the diagnosis of Attention-Deficit/Hyperactivity Disorder (ADHD) to PDD children. The present study elucidates the similarities and differences of ADHD symptoms in PDD children compared to ADHD children.

Methods: Twenty-seven male children with PDD+ADHD Combined type (ADHD-C), 17 males with ADHD-C, and 9 males with PDD without ADHD-C, were compared on measures of ADHD symptoms and related behaviors using parent ratings and teacher ratings on the ADHD Rating Scale (ADHDRS), the Child Behavior Checklist (CBCL) and the Teacher Report Form (TRF).

Hyperactivity and comorbidity in Japanese children with attention-deficit/hyperactivity disorder.

No previous study about comorbidity of attention-deficit/hyperactivity disorder (ADHD) in Japan have carried out both a comprehensive investigation using a structured interview and a comparison between ADHD subtypes. The aim of the present study was to clarify the relationship between hyperactivity and disruptive behavior disorder (DBD) in ADHD by comparing a hyperactivity group (HG) with a non-hyperactivity group (non-HG). After diagnosis was carried out by strict exclusion, the 41 ADHD subjects (6-14 years old; IQ, 70-121) diagnosed according to DSM-IV were divided into HG (n = 24) and non-HG (n = 17), and compared for comorbidities and psychopathologies.
