(„In a related article, Durrant and Ensom4 summarize research done over the last 20 years suggesting that the physical punishment of children is associated with increased levels of child aggression and is no better at eliciting compliance than other methods. Furthermore, physical punishment during childhood is associated with behavioural problems in adult life, including depression, unhappiness, anxiety, feelings of hopelessness, use of drugs and alcohol, and general psychological maladjustment.”)

-Durrant i Ensom4 sumiraju istraživanja urađena u poslednjih 20 godina, koja sugerišu da je fizičko kažnjavanje dece povezano sa povećanim nivoima dečije agresivnosti i nije bolji metod u izazivanju poštovanja u odnosu na druge metode. Osim toga, fizičko kažnjavanje u detinjstvu je povezan sa problemima u ponašanju u odraslom dobu, uključujući depresiju, nesrećom, anksioznost, osećanje bespomoćnosti, upotrebe droga i alkohola, kao i opšte psihološke neprilagođenosti.
