Neglect is the most common form of child maltreatment in the UK and the USA. This article reviews research about how child neglect is perceived by social workers. We conducted a systematic review and identified fifty relevant studies, using a range of methodologies, published since the 1989 Children Act. The themes were identified iteratively and synthesised using a narrative method. The review found that despite evidence that neglect is associated with several adverse outcomes, neglect is a lower priority for social work intervention compared to other forms of maltreatment. This is particularly true for emotional neglect and neglect of older children. The review found that social workers conceptualise poverty and neglect as being distinctly different and try to address poverty through practical, non-punitive interventions. However, assessments could better recognise how deprivation exacerbates other risk factors for neglect. The review found a lack of knowledge about perceptions of neglect in adolescents and children with a disability and about the threshold for intervention when neglect is cumulative. Practice may be improved by better recognising and addressing the societal context to neglect allegations and the risk of long-term harm. Achieving this may have resource and training implications.
