['We sought to determine if maternal depression contributed to the use of corporal punishment in children with attention-deficit/hyperactivity disorder (ADHD).', 'The data were gathered through chart review of clinic-referred children with ADHD and their mothers who were evaluated at a psychiatric clinic located in a large academic medical center in Seoul, Korea. Daily records kept by parents and 13 items from the Physical Assault of the Parent-Child Conflict Tactics Scales (CTSPC) were used to assess corporal punishment. Ninety-one children with ADHD and their mothers were included in this study.', 'Mothers who used corporal punishment showed significantly higher scores on the Beck Depression Inventory (t = -2.952, df = 89, p < 0.01) than mothers who did not. Moreover, maternal depression contributed to the use of corporal punishment in ADHD children (Nagelkerke R2 = 0.102, p < 0.05).'] Does maternal depression predict maternal use of corporal punishment in children with attention-deficit/hyperactivity disorder?
