The scope of the paper is limited to preventive interventions for children at risk for psychosocial problems and child maltreatment. A selected parent training model, the Triple P — Positive Parenting Program (Triple P; Sanders, 1999) is highlighted because it has emerged as a leader in the use of a rigorous, multi-level, prevention-focused assessment methodology. This paper adds to the extant literature by providing a theoretical review of assessment within preventive interventions and reviewing the Triple P approach to implementing this methodology successfully. Future directions are discussed.
