Recent research has demonstrated an associative link between some form
s of mental illness and violence. While much of this violence is commi
tted by persons with schizophrenia, the characteristics of violent ver
sus nonviolent schizophrenic patients has received limited attention.
Two studies with small sample sizes compared these groups on psycholog
ical dimensions in acute care settings, but there appears to be no stu
dy of continuing care inpatients. This study compared a statewide samp
le of violent and nonviolent inpatients with schizophrenia on several
domains of-social interpersonal behavior. In a between-group analysis,
violent patients showed evidence of serious dysfunction in community
self-care and community adjustment, whereas the nonviolent were more i
mpaired in the areas of depression, restlessness, and internal confusi
on. A within-group analysis of patients with interpersonal violence an
d those with noninterpersonal violence yielded similar findings of ser
ious community dysfunction versus internal confusion. The implications
are discussed.
