Physical punishment is
associated with a range of mental health problems in children, youth and adults, including depression, unhappiness, anxiety, feelings of hopelessness, use of drugs and alcohol, and general psychological maladjustment.26 — 29 These relationships may be mediated by disruptions in parent — child attachment resulting from pain inflicted by a caregiver, 30,31 by increased levels of cortisol32 or by chemical disruption of the brain's mechanism for regulating stress.33 Researchers are also finding that physical punishment is linked to slower
cognitive development and adversely affects academic achievement.34 These findings come from large longitudinal studies that control for a wide range of potential confounders.35 Intriguing results are now emerging from neuroimaging studies, which suggest that physical punishment may reduce the volume of the brain's grey matter in areas
associated with performance on the Wechsler Adult Intelligence Scale, third edition (WAIS - III).36 In addition, physical punishment can cause alterations in the dopaminergic regions
associated with
vulnerability to the abuse of drugs and alcohol.37
Past research examining the validity of PCS in Chinese samples has indicated that it is positively
associated with other measures of
cognitive vulnerability including the children's dysfunctional attitudes scale as well as negatively correlated with levels of stress, anxiety, and depression (Auerbach et al. 2009a, b).
Results suggest that higher levels of attachment insecurity were
associated with increased psychological symptoms, higher levels of
cognitive vulnerabilities, and greater general and relationship impairments.
