Mental health and rape history in relation to non-medical use of prescription drugs in a national sample of women

The current study examined prevalence and correlates of non-medical use of prescription drugs (NMUPD), with particular emphasis on lifetime history of rape and PTSD as risk associates.Interviews conducted via telephone using Computer-Assisted Telephone Interviewing technology, resulting in a nationally representative sample of 3001 non-institutionalized, civilian, English or Spanish speaking women (aged 18–86 years) residing in households with a telephone. Demographic characteristics, rape history, general health/mental health, and substance abuse variables were assessed. NMUPD was assessed by asking if, in the past year, participants had misused a prescription drug. Multivariable logistic regressions were conducted for each theoretically derived predictor set. Significant predictors from each set then entered into final multivariable logistic regression to determine significant predictors of past-year NMUPD.NMUPD was endorsed by 5.5% of the sample (n =  164). Final multivariable model showed that Lifetime Posttraumatic Stress Disorder, other forms of substance use/abuse, and a history of drug or alcohol facilitated rape were significantly associated with increased likelihood of NMUPD. Risk reduction efforts targeting non-medical prescription drug use among women who have experienced traumatic events and/or abuse substances are warranted. Trauma-focused interventions for drug or alcohol facilitated rape victims should include treatment or prevention modules that specifically address NMUPD.
