[Screening for risk of child abuse and neglect. A practicable method?].

Selective primary prevention programs for child abuse and neglect depend on risk screening instruments that have the goal of systematically identifying families who can profit most from early help. Based on a systematic review of longitudinal studies, a set of established risk factors for early child abuse and neglect is presented. Nearly half of the items included in screening instruments can be seen as validated. Available studies indicate a high sensitivity of risk screening instruments. Positive predictive values, however, are low. Overall, the use of risk screening instruments in the area of primary prevention for families at risk represents a feasible method, as long as stigmatizing effects can be avoided and participating families also benefit beyond preventing endangerment.
