Suicide-related behavior (SRB) is significantly more prevalent among female (40.8%) than among male (28%) inmates, although suicide risk is higher among the latter. When instrumental behavior (IB) is excluded and only suicidal acts (SA) considered, rates for the two groups are more comparable (11.9% and 16%, respectively). Compared with other female inmates, the SRB group is more suicidal, hostile, and impulsive and more likely to have been previously victimized and to be diagnosed with Axis I and II disorders. Women with IB are not significantly different from those with SA, except that their behavior provides significantly greater tension release.
