Physical Health Consequences
The immediate physical effects of abuse or neglect can be relatively minor (bruises or cuts) or severe (broken bones, hemorrhage, or even death). In some cases the physical effects are temporary; however, the pain and suffering they cause a child should not be discounted. Meanwhile, the long-term impact of child abuse and neglect on physical health is just beginning to be explored. Below are some outcomes researchers have identified:

Shaken baby syndrome. The immediate effects of shaking a baby, which is a common form of child abuse in infants, can include vomiting, concussion, respiratory distress, seizures, and death. Long-term consequences can include blindness, learning disabilities, mental retardation, cerebral palsy, or paralysis (Conway, 1998).

Impaired brain development. Child abuse and neglect have been shown, in some cases, to cause important regions of the brain to fail to form properly, resulting in impaired physical, mental, and emotional development (Perry, 2002; Shore, 1997). In other cases, the stress of chronic abuse causes a "hyperarousal" response by certain areas of the brain, which may result in hyperactivity, sleep disturbances, and anxiety, as well as increased vulnerability to post-traumatic stress disorder, attention deficit/hyperactivity disorder, conduct disorder, and learning and memory difficulties (Dallam, 2001; Perry, 2001).

Poor physical health. A study of 700 children who had been in foster care for 1 year found that more than one-quarter of the children had some kind of recurring physical or mental health problem (U.S. Department of Health and Human Services, 2003). A study of 9,500 HMO participants showed a relationship between various forms of household dysfunction (including childhood abuse) and long-term health problems such as sexually transmitted diseases, heart disease, cancer, chronic lung disease, skeletal fractures, and liver disease (Felitti et al., 1998; Hillis, Anda, Felitti, Nordenberg, & Marchbanks, 2000).  Top

Psychological Consequences
The immediate emotional effects of abuse and neglect—isolation, fear, and an inability to trust—can translate into lifelong consequences, including low self-esteem, depression, and relationship difficulties. Researchers have identified links between child abuse and neglect and the following:

Poor mental and emotional health. In one long-term study, as many as 80 percent of young adults who had been abused met the diagnostic criteria for at least one psychiatric disorder at age 21. These young adults exhibited many problems, including depression, anxiety, eating disorders, and suicide attempts (Silverman, Reinherz, & Giaconia, 1996). Other psychological and emotional conditions associated with abuse and neglect include panic disorder, dissociative disorders, attention-deficit/hyperactivity disorder, posttraumatic stress disorder, and reactive attachment disorder (Teicher, 2000).

Cognitive difficulties. The National Survey of Child and Adolescent Well-Being found that children placed in out-of-home care due to abuse or neglect tended to score lower than the general population on measures of cognitive capacity, language development, and academic achievement (U.S. Department of Health and Human Services, 2003).

Social difficulties. Children who are abused and neglected by caretakers often do not form secure attachments to them. These early attachment difficulties can lead to later difficulties in relationships with other adults as well as with peers (Morrison, Frank, Holland, & Kates, 1999).  Top

Behavioral Consequences
Not all victims of child abuse and neglect will experience behavioral consequences; however, child abuse and neglect appear to make the following more likely:

Difficulties during adolescence. Studies have found abused and neglected children to be at least 25 percent more likely to experience problems such as delinquency, teen pregnancy, low academic achievement, drug use, and mental health problems (Kelley, Thornberry, & Smith, 1997).  

Juvenile delinquency and adult criminality. A National Institute of Justice study indicated being abused or neglected as a child increased the likelihood of arrest as a juvenile by 59 percent. Abuse and neglect increased the likelihood of adult criminal behavior by 28 percent and violent crime by 30 percent (Widom & Maxfield, 2001).

Alcohol and other drug abuse. Research consistently reflects an increased likelihood that abused and neglected children will smoke cigarettes, abuse alcohol, or take illicit drugs. According to a report from the National Institute on Drug Abuse, as many as two-thirds of people in drug treatment programs reported being abused as children (Swan, 1998).

Abusive behavior. Abusive parents often have experienced abuse during their own childhoods. It is estimated approximately one-third of abused and neglected children will eventually victimize their own children (Prevent Child Abuse New York, 2003).  Top

Societal Consequences
While child abuse and neglect almost always occur within the family, the impact does not end there. Society as a whole pays a price for child abuse and neglect, in terms of both direct and indirect costs.

Direct costs. Direct costs include those associated with maintaining a child welfare system to investigate allegations of child abuse and neglect, as well as expenditures by the judicial, law enforcement, health, and mental health systems to respond to and treat abused children and their families. A 2001 report by Prevent Child Abuse America estimates these costs at $24 billion per year.

Indirect costs. Indirect costs represent the long-term economic consequences of child abuse and neglect. These include juvenile and adult criminal activity, mental illness, substance abuse, and domestic violence. They can also include loss of productivity due to unemployment and underemployment, the cost of special education services, and increased use of the health care system. Prevent Child Abuse America recently estimated these costs at more than $69 billion per year (2001).  Top

Summary
Much research has been done about the possible consequences of child abuse and neglect. The effects vary depending on the circumstances of the abuse or neglect, personal characteristics of the child, and the child's environment. Consequences may be mild or severe; disappear after a short period or last a lifetime; and affect the child physically, psychologically, behaviorally, or in some combination of all three ways. Ultimately, due to related costs to public entities such as the health care, human services, and educational systems, abuse and neglect impact not just the child and family, but society as a whole.
