  4. Prevalence of Intimate Partner Violence • In the US, 29.7% of women (18-65 yrs) report lifetime IPV victimization with African Americans overrepresented (33%) (Coker et al., 2002). • High rates of IPV (30-66% ) have been reported in Afro-Caribbean countries (Krug, Dahlberg, Mercy et al., 2002), but actual prevalence in US Virgin Islands never determined. • Health disparities for African American women – including maternal child health disparities & HIV/AIDS also associated with IPV (Sharps & Campbell, 2006; Campbell et al., 2008).

  5. Intersecting Epidemics of IPV, Substance Use and Mental Health • Abused women found to have increased risks of psychosocial and mental health illnesses such as substance use, family and social problems, depression, and anxiety/neuroses compared to never-abused women (Bonomi et al., 2009). • Substance use by both the woman and her partner has been found to independently predict IPV; social support moderated the effect of women’s substance use (Golinelli, et al, 2009).

  6. Purpose • To examine the association between intimate partner violence (IPV) and substance use among Afro Caribbean women in the US Virgin Islands and African American women in Baltimore city, Maryland. • To assess post-traumatic stress disorder as a mediating variable in the relationship between IPV and substance use among Afro Caribbean and African American women.

  7. Methods • Comparative case (N = 150 in each site) control (N = 150 in each site) study • Eligibility criteria • Women aged 18-55 years • Self-identify as Afro Caribbean or African American • Report of a male sex partner in the past two years • Women recruited from primary care, prenatal or family planning clinics • Questionnaire administered on a touch screen computer with optional headphones - an important methodological strategy • For women of low literacy • For sensitive information • Alerts interviewer if high score on DA or suicidality • Allows increased recruitment among Spanish speaking • Recording in Spanish & English by USVI residents • for increased cultural appropriateness • Study period 12/1/09 to present

  8. Measures • Intimate Partner Violence (IPV) in one’s lifetime assessed using the Abuse Assessment Screen (McFarlane & Helton - • Pushed, slapped, hit, kicked, or physically hurt &/OR • Forced sex &/OR • Pushed, slapped, hit, kicked, or physically hurt while currently pregnant • Any of the above by current or former husband, boyfriend, or male or female partner

  9. Measures • Substance Use • Drug use in past yr (street, over the counter, non- prescription drugs) • Alcohol use in past month • Cases with history of sexual violence – they or abusive partner under influence of alcohol or drugs during last forced sex incident • Cases – recent abusive partner drug user • Post-traumatic Stress Disorder (PTSD) • Assessed using 4-item Primary Care-PTSD • Scores summed; cutoff of 3 or more = PTSD+

  10. Study Population 1,201 screened from both sites 1,025 eligible US Virgin Islands Baltimore City, MD n=727 n=298 333 cases 88 controls 306 unselected controls 119 cases 104 controls 75 unselected controls As of 9/10/10

  11. Population-based Prevalence of Lifetime Intimate Partner Violence

  12. Population-based Prevalence of Lifetime Psychological Abuse Only Psychological abuse (above cutoff on WEB (Women’s Experiences of Battering) – being afraid &/or controlled by a current or ex-intimate partner

  13. Population-based Prevalence of Intimate Partner Violence in the Past 2 years n=63

  14. Perpetrator of IPV in the Past 2 years

  15. Demographics Age Employment

  16. Demographics - Education Baltimore USVI X 2 =2.42, p=0.49 X 2 =3.63, p=0.30

  17. Demographics – Marital Status Baltimore USVI X 2 =8.62, p<0.05 X 2 =1.10, p=0.78

  18. Proportion of women reporting drug and alcohol use (452 cases and 192 controls) X 2 =0.044, p=0.83 X 2 =12.74, p<0.001 *in the past year;**in the past month

  19. Does PTSD Mediate the Association Between IPV and Drug Use? Step 1: Is IPV associated with drug use? OR: 3.93; 95% CI: 1.76-8.78 Step 2: Is IPV associated with PTSD (mediator)? OR: 3.88; 95% CI: 2.19-6.88 Step 3: Is PTSD associated with drug use, adjusting for IPV? OR: 3.06; 95% CI: 1.69-5.51 Step 4: Significance testing using the Sobel Test p<0.013

  20. Proportion of women reporting substance use involvement during last forced sex among those with histories of sexual violence(n=135)

  21. Proportion of abused women reporting a recent substance-using partner (n=452) Note: These women 2 times were more likely to have PTSD symptoms in the past month (AdjOR: 2.09; 95% CI: 1.27-3.43).

  22. Conclusions • High rates of IPV, substance use and PTSD among women of African heritage in Baltimore and USVI • High rates of drug use for both abuser and victim in context of forced sex • High rate of drug use by abusers • IPV is associated with drug use but not alcohol use • PTSD mediates the relationship between IPV and victim drug use – self medication hypothesis • Abused women w/substance using abuser more likely to have PTSD • Use of substances as a way to cope with Sx of PTSD

  23. Implications • Women disclosing substance use and PTSD need further assessment to include IPV • Women in substance abuse Tx need assessment and interventions for IPV & PTSD • Women disclosing IPV need further assessment to include substance use and PTSD • Interventions targeting abusive partners should take into account substance abuse history
