an examination of the factor structure of the psychopathy checklist

When a weapon was involved, an object (e.g., bottle of alcohol) was the most common
(48.9%) followed by a knife (38.3%); a chemical spray was the least common (4.3%),
and the type of weapon was unknown in 8.5% of cases. Weapons were obtained
opportunistically in 42.6% of offenses involving a weapon, and were obtained by choice,
prior to the offense in 38.3% of offenses. It was unclear how the weapon was obtained
in 19.1% of offenses that involved a weapon.
Regarding violence severity, over half of the offenses (55.4%) involved physical
violence with no weapon use, 26.9% involved physical violence with weapon use, and
13.1% involved no physical violence and no weapon use. Injuries were most often minor
(57.7%; e.g., bruises, minor medical treatment), 2.3% of victims were severely injured
(e.g., lasting impairment or life-threatening injury), 7.7% of victims were seriously injured
(e.g., required substantial hospital treatment), 12.3% were assaulted without injury, and
in 13.8% of offenses, no assault occurred (e.g., victim was threatened with a weapon).
In one offense (1.0%), the injuries suffered by the victim resulted in his/her death. For a
graphical display of violence severity based on victim injury, refer to Figure 2.
