Internet-Based Behavioural Parent Training Intervention for Children With Attention Deficit/Hyperactivity Disorder

The study design was a 2-parallel-group experimental longitudinal study. Firstly, the children received a diagnostic interview by an experienced child and adolescent psychiatrist at Wuhan Mental Health Centre for confirmation of inclusion and exclusion criteria. Parents who were eligible for the inclusion criteria and interested in the internet-based behavioural Parent Training (I-BPT) program were recruited. After the assessments of ADHD symptoms and psychiatric comorbidity, participants were randomly assigned in a 1:1 ratio to either the routine clinical care (RCC) group or I-BPT+RCC group using computer-generated randomization numbers. Participants in the I-BPT+RCC group were offered 2 months (8 weeks) of internet-assisted parent training in addition to routine outpatient treatment. The RCC group initially received only routine outpatient treatment, yet, after post-follow-up assessment, they were provided with the same I-BPT intervention for ethical considerations. Both groups were followed up after intervention by electronic questionnaire.
