Violence is the use of physical force to cause harm to people, animals, or property, such as pain, injury, death, damage, or destruction. Some definitions are somewhat broader, such as the World Health Organization's definition of violence as "the intentional use of physical force or power, threatened or actual, against oneself, another person, or against a group or community, which either results in or has a high likelihood of resulting in injury, death, psychological harm, maldevelopment, or deprivation."
Abuse is the improper usage or treatment of a thing, often to unfairly or improperly gain benefit. Abuse can come in many forms, such as: physical or verbal maltreatment, injury, assault, violation, rape, unjust practices, crimes, or other types of aggression. To these descriptions, one can also add the Kantian notion of the wrongness of using another human being as means to an end rather than as ends in themselves. Some sources describe abuse as "socially constructed", which means there may be more or less recognition of the suffering of a victim at different times and societies.
Psychological abuse, often called emotional abuse, is a form of abuse characterized by a person subjecting or exposing another person to a behavior that may result in psychological trauma, including anxiety, chronic depression, or post-traumatic stress disorder amongst other psychological problems.
Child abuse is physical, sexual, emotional and/or psychological maltreatment or neglect of a child, especially by a parent or a caregiver. Child abuse may include any act or failure to act by a parent or a caregiver that results in actual or potential wrongful harm to a child and can occur in a child's home, or in organizations, schools, or communities the child interacts with.
Sibling abuse includes the physical, psychological, or sexual abuse of one sibling by another. More often than not, the younger sibling is abused by the older sibling. Sibling abuse is the most common of family violence in the US, but the least reported. As opposed to sibling rivalry, sibling abuse is characterized by the one-sided treatment of one sibling to another.
Childhood trauma is often described as serious adverse childhood experiences (ACEs). Children may go through a range of experiences that classify as psychological trauma; these might include neglect, abandonment, sexual abuse, emotional abuse, and physical abuse, witnessing abuse of a sibling or parent, or having a mentally ill parent. These events have profound psychological, physiological, and sociological impacts and can have negative, lasting effects on health and well-being such as unsocial behaviors, attention deficit hyperactivity disorder (ADHD), and sleep disturbances. Similarly, children whose mothers have experienced traumatic or stressful events during pregnancy have an increased risk of mental health disorders and other neurodevelopmental disorders.
Child sexual abuse (CSA), also called child molestation, is a form of child abuse in which an adult or older adolescent uses a child for sexual stimulation. Forms of child sexual abuse include engaging in sexual activities with a child, indecent exposure, child grooming, and child sexual exploitation, such as using a child to produce child pornography.
The effects of domestic violence on children have a tremendous impact on the well-being and developmental growth of children witnessing it. Children who witness domestic violence in the home often believe that they are to blame, live in a constant state of fear, and are 15 times more likely to be victims of child abuse. Close observation during an interaction can alert providers to the need for further investigation and intervention, such as dysfunctions in the physical, behavioral, emotional, and social areas of life, and can aid in early intervention and assistance for child victims.
Child neglect, often overlooked, is the most common form of child maltreatment. Most perpetrators of child abuse and neglect are the parents themselves. A total of 79.4% of the perpetrators of abused and neglected children are the parents of the victims, and of those 79.4% parents, 61% exclusively neglect their children. The physical, emotional, and cognitive developmental impacts from early childhood neglect can be detrimental, as the effects from the neglect can carry on into adulthood.

People in prison are more likely than the general United States population to have received a mental disorder diagnosis, and women in prison have higher rates of mental illness and mental health treatment than do men in prison. Furthermore, women in prisons are three times more likely than the general population to report poor physical and mental health. Women are the fastest growing demographic of the United States prison population. As of 2019, there are about 222,500 women incarcerated in state and federal prisons in the United States. Women comprise roughly 8% of all inmates in the United States.

Adverse childhood experiences (ACEs) include childhood emotional, physical, or sexual abuse and household dysfunction during childhood. The categories are verbal abuse, physical abuse, contact sexual abuse, a battered mother, household substance abuse, household mental illness, incarcerated household members, and parental separation or divorce. The experiences chosen were based upon prior research that has shown to them to have significant negative health or social implications, and for which substantial efforts are being made in the public and private sector to reduce their frequency of occurrence. Scientific evidence is mounting that such adverse childhood experiences (ACEs) have a profound long-term effect on health. Research shows that exposure to abuse and to serious forms of family dysfunction in the childhood family environment are likely to activate the stress response, thus potentially disrupting the developing nervous, immune, and metabolic systems of children. ACEs are associated with lifelong physical and mental health problems that emerge in adolescence and persist into adulthood, including cardiovascular disease, chronic obstructive pulmonary disease, autoimmune diseases, substance abuse, and depression.

The influence of childhood trauma on the development of psychopathy in adulthood remains an active research question. According to Hervey M. Cleckley, a psychopathic person is someone who is able to imitate a normal functioning person, while masking or concealing their lack of internal personality structure. This results in an internal disorder with recurrent deliberate and detrimental conduct. Despite presenting themselves as serious, bright, and charming, psychopathic people are unable to experience true emotions. Robert Hare's two factor model and Christopher Patrick's triarchic model have both been developed to better understand psychopathology; however, whether the root cause is primarily environmental or primarily genetic is still in question.
A juvenile sex crime is defined as a legally proscribed sexual crime committed without consent by a minor under the age of 18. The act involves coercion, manipulation, a power imbalance between the perpetrator and victim, and threats of violence. The sexual offenses that fall under juvenile sex crimes range from non-contact to penetration. The severity of the sexual assault in the crime committed is often the amount of trauma and/or injuries the victim has suffered. Typically within these crimes, female children are the majority demographic of those targeted and the majority of offenders are male. Juvenile sex offenders are different than adult sex offenders in a few ways, as captured by National Incident Based Reporting System: they are more likely to be committed in school, offend in groups and against acquaintances, target young children as victims, and to have a male victim, whereas they are less likely than their adult counterpart to commit rape.
