Violent typologies among women inpatients with severe mental illness

Extant severe mental illness (SMI) and physical violence literature focus disproportionately on community-based men samples. To address this empirical imbalance, the current study explored violence towards others and oneself among women inpatients with SMI. As those with SMI are more likely to be victims than perpetrators of violence, victimisation was also an important factor assessed in this study.

The study used a quantitative within-subject cross-sectional design. Data were extracted from 5675 inpatient women cases between 2009 and 2013.

Women with a manic disorder (without psychotic features) were 4.5 times, whilst those with psychotic disorders were 2 times, more likely to be physically violent to others compared to those with major mood disorders. Conversely, women with a major mood disorders were 4.8 times and 7.5 times more likely to engage in violence towards oneself (deliberate self-harm), compared to those with psychotic disorder and manic disorders, respectively. The past victimisation increased the likelihood of later physical violence.

The data illuminate differential risk factors among women inpatients with SMI that may help predict violence occurring towards others and oneself and allow gender comparisons with the established literature.
