Patterns of injuries: accident or abuse.

This study uses two types of independent variables, age and the location of the physical wound, to develop a model of injury patterning that identifies violent behavior without direct observation of the assault. In this research, domestic violence injuries are compared to accidental injuries. The results indicate that there are specific and predictable injury patterns that separate abuse from other kinds of wounds. A logistic regression model was developed to identify the regions of the body most susceptible to injury from domestic assault. Using the age of the victim and the injury regions, probabilities were calculated to determine which wounds were caused by abuse.
