A dysfunctional family is a family in which conflict, misbehavior, and often child neglect or abuse on the part of individual parents occur continually and regularly, leading other members to accommodate such actions. Children sometimes grow up in such families with the understanding that such an arrangement is normal. Dysfunctional families are primarily a result of codependent adults, and may also be affected by addictions, such as substance abuse (e.g., alcohol and/or drugs), or sometimes an untreated mental illness. Dysfunctional parents may emulate or over-correct from their own dysfunctional parents. In some cases, a "child-like" parent will allow the dominant parent to abuse their children.
A common misperception of dysfunctional families is the mistaken belief that the parents are on the verge of separation and divorce. While this is true in a few cases, often the marriage bond is very strong as the parents' faults actually complement each other. In short, they have nowhere else to go. However, this does not necessarily mean the family's situation is stable. Any major stressor, such as relocation, unemployment/underemployment, physical or mental illness, natural disaster, etc. can cause existing conflicts affecting the children to become much worse.
Dysfunctional families have no social, financial or intellectual bounds. Nevertheless, until recent decades the concept of a dysfunctional family was not taken seriously by professionals (therapists, social workers, teachers, counselors, clergy, etc.), especially among the middle and upper classes. Any intervention would have been seen as violating the sanctity of marriage and increasing the probability of divorce, which was socially unacceptable at the time. Historically, children of dysfunctional families were expected to obey their parents (ultimately the father), and to cope with the situation alone.
Dysfunctional family members have common features and behavior patterns as a result of their experiences within the family structure. This tends to reinforce the dysfunctional behavior, either through enabling or perpetuation. The family unit can be affected by a variety of factors.
