Changes in Behaviour Symptoms of Patients with Attention Deficit/Hyperactivity Disorder during Treatment: Observation from Different Informants

摘要

Objective The aim of this study was to determine changes in behaviour among patients with attention deficit/hyperactivity disorder (ADHD) by different informants during treatment in the clinical setting. Methods Seventy-nine patients with ADHD were recruited. They completed 12-months of treatment with oral short-acting methylphenidate, two-to-three times per day, at a dose of 0.3-1.0 mg/kg. Among the 79 patients (mean age, 9.1±1.9 years), 39 were classified as the ADHD-C/H type (hyperactive-impulsive type and combined type) and 40 as the ADHD-I type (inattentive type). At baseline, and after 12 months, their behaviour was assessed using the Child Behaviour Checklist (CBCL), Teacher's Report Form (TRF), ADHD Rating Scale (ADHD-RS), and Clinical Global Impression-Severity (CGI-S). Results Patients classified as the ADHD-C/H type had higher scores on three CBCL subscales, on the ADHD-RS and CGI-S compared to the ADHD-I type patients. After 12-months of treatment, for all patients, there were significant improvements in the four subscales of the TRF as well as the ADHD-RS and CGI-S scores, but not on the CBCL. In addition, the patients with the ADHD-C/H type had greater improvements on the four subscales of the TRF after treatment. However, there were no differences noted on the CBCL, ADHD-RS and CGI-S. Conclusion The results of this study showed that during treatment, in the clinical setting, there are different assessments of behaviour symptoms, associated with ADHD, reported by different informants. Assessments of behaviour profiles from multiple informants are crucial for establishing a fuller picture of patients with ADHD.
