The SRP is a structured professional judgment instrument that guides risk assessment in stalking situations. Stalking—a pattern of targeted, repeated, and unwanted intrusive acts—can cause significant harm to victims, particularly when it is persistent or involves physical violence. The SRP provides a structure for assessing the likelihood of these outcomes by evaluating the presence of risk factors linked to each. Judgments made using the SRP can help professionals to more effectively allocate resources to manage stalking situations. This entry describes the development of the SRP, outlines its use, describes its structure, and reviews the empirical evidence for the reliability and validity of the SRP.
