The CAP Inventory was designed primarily as a screening tool for the detection of physical child abuse by protective services workers in their investigations of reported child abuse cases. The CAP Inventory is a 160-item, reliable and valid objective self-report screening instrument that can assist protective services workers in making case decisions. It contains a total of 10 scales. The primary clinical scale (Abuse) can be divided into six-factor scales: Distress, Rigidity, Unhappiness, Problems With Child and Self, Problems With Family, and Problems With Others. In addition, the CAP Inventory contains three validity scales: Lie, Random Response, and Inconsistency.
