English et al. report that children whose families are characterized by interpersonal violence, including psychological aggression and verbal aggression, may exhibit a range of serious disorders, including chronic depression, anxiety, post-traumatic stress disorder, dissociation and anger. Additionally, English et al. report that the impact of emotional abuse "did not differ significantly" from that of physical abuse. Johnson et al. report that, in a survey of female patients, 24% suffered emotional abuse, and that this group experienced higher rates of gynecological problems. In their study of men emotionally abused by a wife/partner or parent, Hines and Malley-Morrison report that victims exhibit high rates of post-traumatic stress disorder and drug addiction, including alcoholism.
