A Longitudinal Investigation of Intimate Partner Violence Among Mothers With Mental Illness

Abstract

Severe mental illness, substance use, and intimate partner violence have emerged as major intersecting public health problems that adversely and disproportionately impact the lives of women in the United States. This longitudinal study investigated the demographic and clinical correlates of intimate partner violence in a sample of 324 mothers with severe mental illness. A secondary analysis of longitudinal data was conducted by using multiple logistic regression. Participants were part of a longitudinal, community-based study of mothers with severe mental illness, which was aimed at understanding how these mothers viewed motherhood. The women were interviewed initially at baseline (interviews were conducted between 1995 and 1996) and then about 20 months later at follow-up (interviews were conducted between 1997 and 1998). At follow-up the prevalence rate of intimate partner violence was 19%. Multiple logistic regression analyses showed a significant positive relationship between alcohol and drug misuse at baseline and intimate partner violence at follow-up, indicating that women with a co-occurring diagnosis of a substance use disorder (dual diagnosis) were more likely than women without such a diagnosis to report intimate partner violence. The number of lifetime psychiatric hospitalizations and the number of symptoms related to psychiatric disability exhibited at baseline were positively associated with intimate partner violence at follow-up, and age was inversely associated with intimate partner violence. Mental health professionals serving mothers with mental health problems need to be aware of and prepared to assess the significant correlation between these intersecting public health problems in order to influence successful interventions. Particular attention must be given to the special treatment needs related to dual diagnosis and victimization and the impact of these factors on this vulnerable population.
