Objective: To compare psychopathology and personality in parents of children with ADHD and control parents. Method: A total of 140 parents were subdivided according to presence and duration of ADHD. Assessment was based on various ADHD self-rating scales, the revised Symptom Checklist (SCL-90-R), the Patient Health Questionnaire (PHQ), and the revised NEO Five Factors Inventory (NEO-FFI). Results: Parents with lifelong persistent ADHD were most abnormal on all dimensions of ADHD psychopathology, the SCL-90-R, the PHQ, and the neuroticism and conscientiousness dimensions of the NEO-FFI. The scores of parents with current ADHD approached those of parents with persistent ADHD on most dimensions, and both groups scored higher than did parents with either remitted ADHD or no ADHD, or controls. The scores of the latter three groups were not significantly different from each other. Conclusion: Among parents of children with ADHD, parents with lifelong persistent or current ADHD show highest scores of psychopathology.
