Abstract
Objective: The authors examine how many Aboriginal children attending two reservation-based elementary schools in Northern Alberta, Canada, would demonstrate symptoms associated with ADHD using standardized parent and teacher questionnaires. Method: Seventy-five Aboriginal children in Grades 1 through 4 are tested. Seventeen of the 75 (22.7%) Aboriginal children demonstrated a match on parent and teacher forms, with T-scores greater than 1.5 standard deviations from the mean on the Conners’ ADHD Index, Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV) Hyperactive/Impulsive Index, DSM-IV Inattentive Index, and/or DSM-IV Total Combined T-score. Results: The number of Aboriginal children found to have symptoms associated with ADHD is significantly higher than expected based on prevalence rates in the general population. Conclusion: These findings suggest either a high prevalence of ADHD in Aboriginal children or unique learning and behavioral patterns in Aboriginal children that may erroneously lead to a diagnosis of ADHD if screening questionnaires are used.
