“…These studies cannot be easily compared because the age ranges studied in their samples were not identical. However, the tendency for Japanese parents or teachers to give lower scores to children’s behaviors appears consistent among questionnaires such as the CBCL [29], ADHD-RS [33,34], and Social Responsiveness Scale [40,41]. One partial explanation for the relatively lower scores of Japanese children on behavioral measures such as the SDQ is that Japanese informants tend to respond to Likert-type ratings by choosing the scale’s midpoint, whereas U.S. informants tend to choose the scale’s extreme values [42].…”

“…Each item is scored on a 4-point scale, and inattention (sum of odd-numbered items), hyperactivity-impulsivity (sum of even-numbered items), and total score (sum of all items) can be calculated. The Japanese versions of the ADHD-RS home and school forms were shown to be valid, reliable, and to have a two-factor structure [33,34]. In this study, 41 parents and 43 teachers of primary schoolchildren completed the home form and school form, respectively.…”

BackgroundAlthough child mental health problems are among the most important worldwide issues, development of culturally acceptable mental health services to serve the clinical needs of children and their families is especially lacking in regions outside Europe and North America. The Strengths and Difficulties Questionnaire (SDQ), which was developed in the United Kingdom and is now one of the most widely used measurement tools for screening child psychiatric symptoms, has been translated into Japanese, but culturally calibrated norms for Japanese schoolchildren have yet to be established. To this end, we examined the applicability of the Japanese versions of the parent and teacher SDQs by establishing norms and extending validation of its psychometric properties to a large nationwide sample, as well as to a smaller clinical sample.MethodsThe Japanese versions of the SDQ were completed by parents and teachers of schoolchildren aged 7 to 15 years attending mainstream classes in primary or secondary schools in Japan. Data were analyzed to describe the population distribution and gender/age effects by informant, cut-off scores according to banding, factor structure, cross-scale correlations, and internal consistency for 24,519 parent ratings and 7,977 teacher ratings from a large nationwide sample. Inter-rater and test-retest reliabilities and convergent and divergent validities were confirmed for a smaller validation sample (total n = 128) consisting of a clinical sample with any mental disorder and community children without any diagnoses.ResultsMeans, standard deviations, and banding of normative data for this Japanese child population were obtained. Gender/age effects were significant for both parent and teacher ratings. The original five-factor structure was replicated, and strong cross-scale correlations and internal reliability were shown across all SDQ subscales for this population. Inter-rater agreement was satisfactory, test-retest reliability was excellent, and convergent and divergent validities were satisfactory for the validation sample, with some differences between informants.ConclusionsThis study provides evidence that the Japanese version of the SDQ is a useful instrument for parents and teachers as well as for research purposes. Our findings also emphasize the importance of establishing culturally calibrated norms and boundaries for the instrument’s use.

“…The ADHD-RS is a reliable and easy-to-administer instrument both for diagnosing ADHD in children and adolescents, and for assessing treatment response. Containing 18 items, the scale is linked directly to DSM-IV diagnostic criteria for ADHD (Tani et al, 2010). The Wechsler Intelligence Scale for Children -Third Edition (WISC-III) or Fourth Edition (WISC-IV), Japanese version was used to assess the Full Intelligent Quotient (FIQ) of patients with ADHD (David, , 2010.…”

Attention Deficit/Hyperactivity Disorder (ADHD) and autism spectrum disorder (ASD) are highly comorbid, and both disorders share executive function deficits. Accumulating evidence suggests that ASD patients have significantly lower peripheral oxytocin (OXT) levels compared with their normal counterparts, and that the repetitive behavior seen in ASD is related to abnormalities in the OXT system. In this study, we investigated whether serum levels of OXT are altered in pediatric patients with ADHD. We measured serum OXT levels: drug naive ADHD (n=23), medicated ADHD (n=13), and age- and sex- matched, neurotypical controls (n=22). Patients were evaluated using the ADHD-RS. Serum levels of OXT in total subjects with ADHD were significantly decreased compared with those of neurotypical controls, and serum levels of OXT in drug naive ADHD patients were significantly lower than those in medicated ADHD patients. Interestingly, there was a significant negative correlation between serum OXT levels and ADHD-RS total scores, as well as ADHD-RS inattentive scores in all ADHD patients. In conclusion, this study suggests that decreased levels of OXT may play a role in the pathophysiology of patients with ADHD and its inherent inattentiveness.

BackgroundTipepidine (3-[di-2-thienylmethylene]-1-methylpiperidine) has been used solely as a nonnarcotic antitussive in Japan since 1959. The safety of tipepidine in children and adults has already been established. It is reported that tipepidine inhibits G-protein-coupled inwardly rectifying potassium (GIRK)-channel currents. The inhibition of GIRK channels by tipepidine is expected to modulate the level of monoamines in the brain. We put forward the hypothesis that tipepidine can improve attention deficit/hyperactivity disorder (ADHD) symptoms by modulating monoaminergic neurotransmission through the inhibition of GIRK channels. The purpose of this open-label trial was to confirm whether treatment with tipepidine can improve symptoms in pediatric patients with ADHD.Subjects and methodsThis was a 4-week, open-label, proof-of-efficacy pilot study for pediatric subjects with ADHD. Ten pediatric ADHD subjects (70% male; mean age, 9.9 years; combined [inattentive and hyperactive/impulsive] subtype, n=7; inattentive subtype, n=3; hyperimpulsive subtype, n=0) received tipepidine hibenzate taken orally at 30 mg/day for 4 weeks. All subjects were assessed using the ADHD Rating Scale IV (ADHD-RS), Japanese version, and the Das–Naglieri Cognitive Assessment System (DN-CAS), Japanese version.ResultsA comparison of baseline scores and 4-week end-point scores showed that all the ADHD-RS scores (total scores, hyperimpulsive subscores, and inattentive subscores) improved significantly (P<0.001). Furthermore, a comparison of baseline DN-CAS total scores and 4-week end-point scores showed a mild trend of improvement (P=0.093). Tipepidine was well tolerated, with no patients discontinuing medication because of side effects.ConclusionOur pilot study suggests that tipepidine therapy may prove to be an effective alternative treatment for pediatric patients with ADHD. Nonetheless, more detailed randomized, double-blind trials are needed to confirm tipepidine’s efficacy.
