Study Shows Women Veterans with History of Sexual Abuse at Higher Risk for Substance Use Disorder


BACKGROUND:
Multiple reports have documented a high prevalence of rape and sexual harassment among military women and women Veterans. Research also has shown that women’s experiences of sexual assault or rape are associated with the development of substance use disorders; moreover, adult female victims of rape who experience additional instances of rape show a higher risk of problem substance use. This retrospective cohort study examined the associations between rape history and substance use disorders among 1,004 women Veterans (age <51 years) who received care at two Midwestern VAMCs. Using data from a telephone survey, investigators assessed: demographics, rape history, substance abuse and dependence, depression, and PTSD. Another variable was sexual partnership, which included "men only," "women only," "both men and women," and "no partners." "Women only" and "both men and women" were classified as sexual partnerships with women.

FINDINGS:

  • Lifetime substance abuse disorder was higher for women Veterans with a history of rape.
  • Two-thirds (62%) of study participants reported lifetime sexual assault, including 11% reporting attempted rape and 51% reporting at least one completed rape. Women with women as sex partners had significantly higher rates of rape and lifetime substance use disorder (73% of women with women as sex partners reported lifetime rape vs. 48% of exclusively heterosexual women).
  • Almost the entire study population (97%) reported lifetime use of alcohol, and 77% reported using alcohol in the past year. However, women with lifetime rape were more likely to report abstinence from drinking (50%) than women with no rape (41%).
  • Fewer women Veterans (47%) reported lifetime use of illicit drugs, mainly marijuana (45%), cocaine (16%), hallucinogens (13%), and amphetamines (10%).
  • Women reported the highest rates of rape during childhood and military service (51% and 25%, respectively), and those reporting rape in any period of their lives were significantly more likely to report rape in other periods. For example, women Veterans reporting in-military rape were significantly more likely to report post-military rape (18% vs. 9%).

LIMITATIONS:

  • Only 43% of eligible women who received care at two medical centers were located and participated. Therefore, results may not be generalizeable to all female patients under age 51 or women at other VA medical centers.
  • This was a retrospective study that did not include detailed diagnostic interviews. For example, investigators did not conduct an extensive assessment of the timing between substance abuse and rape self-reports.
  • Investigators relied on validity of alcohol and drug self-report via telephone interviews.

What are HSR&D Publication Briefs?

HSR&D requires notification by HSR&D-funded investigators about all articles accepted for publication. These journal articles are reviewed by HSR&D and publication briefs or summaries are written for a select number of articles that are then forwarded to VHA Central Office leadership to keep them informed about important findings or information. Articles to be summarized are selected by HSR&D based on timeliness of the findings, interest of leadership, or potential impact on the organization. Publication briefs are written for only a small number of HSR&D published articles. Visit the HSR&D citations database for a complete listing of HSR&D articles and presentations.
