Although child neglect is the most common form of child maltreatment, considerable confusion remains regarding its definition. A conceptual definition of neglect is presented based on an ecological model of child maltreatment. The definition focuses on the basic needs of children that are not met, rather than on the intentions or behavior of parents. The replacement of parental culpability by a shared responsibility including parents, families, the community, and society is suggested. Neglect is seen as a heterogeneous phenomenon that varies by type, severity, and chronicity. In addition, neglect is understood as existing on a continuum ranging from optimal to grossly inadequate care. The context within which neglect occurs, including parents' understanding of children's needs, religious and cultural beliefs, and poverty, influences the approaches of clinicians, researchers, and policymakers toward the problem of child neglect.
