Psychometric properties of the Japanese version of the Adult Attention-deficit hyperactivity disorder (ADHD) Self-Report Scale (ASRS-J) and its short scale in accordance with DSM-5 diagnostic criteria.

We developed the Japanese version of the Adult ADHD Self-Report Scale (ASRS-J) and report its psychometric properties. The ASRS-J and other questionnaires were administered to 48 adults with ADHD, 46 adults with non-ADHD psychiatric disorders, 96 non-clinical adults, and 894 university students. ADHD diagnoses were made using the Japanese semi-structured diagnostic interview for adult ADHD, which is compatible with the DSM-5.

Reliability and validity of ADHD diagnostic criteria in the Assessment System for Individuals with ADHD (ASIA): a Japanese semi-structured diagnostic interview.

Background: With reports of a high prevalence of attention-deficit/hyperactivity disorder (ADHD) in adults, publication of ADHD diagnostic criteria in DSM-5, and the urgent need for a relevant diagnostic instrument conforming to DSM-5, we developed the Assessment System for Individuals with ADHD (ASIA), a Japanese semi-structured diagnostic interview. We report here the reliability and validity of ASIA ADHD diagnostic criteria.

Methods: ASIA ADHD criterion A corresponds to DSM-5 ADHD criterion A and has 144 original questions assessing nine inattention symptoms and nine hyperactivity-impulsivity symptoms, each having four childhood and four adulthood questions.

Reliability and validity of the Pervasive Developmental Disorders Assessment System.

Aim: To test the reliability and validity of the Pervasive Developmental Disorders Assessment System (PDDAS), a Japanese semistructured interview system.

Methods: The PDDAS, consisting of 91 items including 12 major items corresponding to 12 items in criterion A of DSM-IV autistic disorder criteria, 36 items on autistic symptoms and three Asperger's disorder (AS) screening items for diagnosing pervasive developmental disorders (PDD) and their subtypes and 40 items for other information including early development and past/family histories, was administered to mothers of 77 PDD children and 64 non-PDD children.

Results: The PDDAS had satisfactory interrater reliability (ranges of kappa, r and raw agreement rate were 0.

Autism-spectrum quotient Japanese version measures mental health problems other than autistic traits.

The purpose of the present paper was to examine the extent to which the Autism Spectrum Quotient Japanese version (AQ-J) measures mental health problems other than autistic traits, with the 12-item General Health Questionnaire Japanese version (GHQ-12) as a criterion. A questionnaire involving AQ-J and GHQ-12 was sent to 2000 adults aged 20-39 randomly selected from the general population, and intact data were obtained from 215 (mean age, 30.4 years; 86 male).

Autism-Spectrum Quotient-Japanese version and its short forms for screening normally intelligent persons with pervasive developmental disorders.

A Japanese version of the Autism Spectrum Quotient (AQ), AQ-J was administered to 25 normally intelligent high-functioning pervasive developmental disorder (HPDD) patients (mean age, 24.2 years; 24 male, one female) and 215 controls (mean age, 30.4 years; 86 male, 129 female) randomly selected from the general population.
