The reliability and validity of the Questionnaire - Children with Difficulties (QCD)

Background: The aim of this study was to evaluate the reliability and validity of the Questionnaire-Children with Difficulties (QCD), which was developed for the evaluation of children's daily life behaviors during specified periods of the day. Methods: The subjects were 1,514 Japanese public elementary and junior high school students. For the examination of reliability, Cronbach's alpha was calculated to assess the internal consistency of the questionnaire. With regard to validity, correlation coefficients were calculated to examine whether QCD scores correlated with those of the ADHD-Rating Scale (ADHD-RS) and the Oppositional Defiant Behavior Inventory (ODBI). Results: Cronbach's alpha coefficient for the total score of the QCD was .876. The correlation coefficients of the QCD score with ADHD-RS and ODBI scores were -.514 and -.577, respectively. Conclusions: The internal consistency and validity of the QCD were demonstrated. The QCD is a reliable and valid instrument for evaluating daily life problems for children during different time periods of the day.ArticleCHILD AND ADOLESCENT PSYCHIATRY AND MENTAL HEALTH. 7:11 (2013)journal articl

Parent–Child Interaction Therapy (PCIT) for young children with Attention-Deficit Hyperactivity Disorder (ADHD) in Japan

Abstract Early intervention for preschoolers with Attention-Deficit Hyperactivity Disorder (ADHD) is important considering the impact on their prognosis. Parent–Child Interaction Therapy (PCIT) is a psychotherapy treatment for the parent–child dyad and has been shown to be effective for children with disruptive behaviors. We present the treatment course of PCIT for two Japanese children with ADHD. Case 1 is a 2-year-old female child with hyperactivity and aggressiveness. Case 2 is a 4-year-old male child with restlessness and intolerability to daily events. For both cases, PCIT was effective in improving the problematic behaviors. PCIT may serve as a treatment option for Japanese children with ADHD

Reliability of Telepsychiatry Assessments Using the Attention-Deficit/Hyperactivity Disorder Rating Scale-IV for Children With Neurodevelopmental Disorders and Their Caregivers: Randomized Feasibility Study

BackgroundGiven the global shortage of child psychiatrists and barriers to specialized care, remote assessment is a promising alternative for diagnosing and managing attention-deficit/hyperactivity disorder (ADHD). However, only a few studies have validated the accuracy and acceptability of these remote methods. ObjectiveThis study aimed to test the agreement between remote and face-to-face assessments. MethodsPatients aged between 6 and 17 years with confirmed Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition diagnoses of ADHD or autism spectrum disorder (ASD) were recruited from multiple institutions. In a randomized order, participants underwent 2 evaluations, face-to-face and remotely, with distinct evaluators administering the ADHD Rating Scale-IV (ADHD-RS-IV). Intraclass correlation coefficient (ICC) was used to assess the reliability of face-to-face and remote assessments. ResultsThe participants included 74 Japanese children aged between 6 and 16 years who were primarily diagnosed with ADHD (43/74, 58%) or ASD (31/74, 42%). A total of 22 (30%) children were diagnosed with both conditions. The ADHD-RS-IV ICCs between face-to-face and remote assessments showed “substantial” agreement in the total ADHD-RS-IV score (ICC=0.769, 95% CI 0.654-0.849; P<.001) according to the Landis and Koch criteria. The ICC in patients with ADHD showed “almost perfect” agreement (ICC=0.816, 95% CI 0.683-0.897; P<.001), whereas in patients with ASD, it showed “substantial” agreement (ICC=0.674, 95% CI 0.420-0.831; P<.001), indicating the high reliability of both methods across both conditions. ConclusionsOur study validated the feasibility and reliability of remote ADHD testing, which has potential benefits such as reduced hospital visits and time-saving effects. Our results highlight the potential of telemedicine in resource-limited areas, clinical trials, and treatment evaluations, necessitating further studies to explore its broader application.
