Evaluation of a Web-Based ADHD Awareness Training in Primary Care: Pilot Randomized Controlled Trial With Nested Interviews

BACKGROUND: Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder affecting up to 5% of children and adults. Undiagnosed and untreated ADHD can result in adverse long-term health, educational, and social impacts for affected individuals. Therefore, it is important to identify this disorder as early as possible. General practitioners (GPs) frequently play a gatekeeper role in access to specialist services in charge of diagnosis and treatment. Studies have shown that their lack of knowledge and understanding about ADHD can create barriers to care. OBJECTIVE: This pilot randomized controlled trial assesses the efficacy of a web-based psychoeducation program on ADHD tailored for GPs. METHODS: A total of 221 participants were randomized to either a sham intervention control or an awareness training intervention and they completed questionnaires on ADHD knowledge, confidence, and attitude at 3 time points (preintervention, postintervention, and 2-week follow-up). Participants in the intervention arm were invited to participate in a survey and follow-up interview between 3 and 6 months after the intervention. RESULTS: The responses of 109 GPs were included in the analysis. The knowledge (P<.001) and confidence (P<.001) of the GPs increased after the intervention, whereas misconceptions decreased (P=.04); this was maintained at the 2-week follow-up (knowledge, P<.001; confidence, P<.001; misconceptions, P=.03). Interviews and surveys also confirmed a change in practice over time. CONCLUSIONS: These findings demonstrate that a short web-based intervention can increase GPs’ understanding, attitude, and practice toward ADHD, potentially improving patients’ access to care.
