Abstract

BackgroundWomen exposed to gender-based violence GBV experience a high rate of common mental disorders and suicidal behaviour -mental disturbance-. Little is known however about the timing of onset of mental disturbance following first exposure to GBV amongst women with no prior mental disorder.

MethodsThe analysis was undertaken on the Australian National Mental Health and Wellbeing Survey dataset N = 8841. We assessed lifetime prevalence and first onset of common mental disorder and suicidal behaviour mental disturbance and exposure to GBV and its first occurrence based on the Composite International Diagnostic Interview Version 3 WMH-CIDI 3.0. We used the Kaplan-Meier method to derive cumulative incident curves for first onset mental disturbance. The two derived subgroups were women who experienced GBV without prior mental disturbance; and women never exposed to GBV stratified to match the former group on age and socio-economic status.

ResultsFor women with no prior mental disorder, the cumulative incidence curves showed a high incidence of all mental disturbances following first GBV, compared to women without exposure to GBV all log rank tests <0.0001. Nearly two fifths 37% of any lifetime mental disturbance had onset in the year following first GBV in women exposed to abuse. For these women, over half 57% of cases of lifetime PTSD had onset in the same time interval. For GBV exposed women, half of all cases of mental disturbance 54% and two thirds of cases of PTSD 66.9% had onset in the five years following first abuse. In contrast, there was a low prevalence of onset of mental disturbance in the comparable imputed time to event period for women never exposed to GBV for any mental disturbance, 1% in the first year, 12% in five years; for PTSD 3% in the first year, 7% in five years.

ConclusionsAmongst women without prior mental disturbance, common mental disorders and suicidal behaviour have a high rate of onset in the one and five year intervals following exposure to GBV. There is a particularly high incidence of PTSD in the first year following GBV.
