Recently, Kristine Schmitz, an assistant professor in the Department of Pediatrics at Robert Wood Johnson Medical School, published a study in the "American Journal of Preventive Medicine" investigating a correlation between paternal depression and child behavioral issues in the classroom. Schmitz said she found that children whose fathers reported depressive symptoms were more likely to exhibit hyperactivity or similar symptoms to attention deficit hyperactivity disorder (ADHD). They were also more likely to experience difficulties in social interactions, she added.
