The research question is: to what extent does the large gender gap in ADHD diagnosis reflect true differences in symptom prevalence, versus patient-side utilization costs, versus physician decision-making under uncertainty? The setting is particularly well-suited to this question because DSM-V diagnostic guidelines for ADHD are explicitly gender-neutral, making any gender difference in physician thresholds a detectable deviation from uniform clinical rules.</p>
