title: 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.
abstract: 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. The ASRS-J, its subscales, and the short form, all had Cronbach's α values of around 0.80. Total scores on the ASRS-J and the ASRS-J-6 were highly correlated with readministration after a two-week interval. The total and 18 individual item scores in the ASRS-J were significantly higher in the ADHD group than the other three groups. ASRS-J scores were correlated with scores on the Japanese version of Conners' Adult ADHD Rating Scales-Self Report subscales (0.59≤r≤0.77), with one exception. ASRS-J scores were also correlated (albeit more weakly; r=0.38) with Beck Depression Inventory-II total scores. Employing optimal cut-offs, sensitivity, specificity, and positive and negative predictive values of the ASRS-J and ASRS-J-6 are all above 0.69. The ASRS-J and ASRS-J-6 showed acceptable psychometric properties, although further study is necessary.
