Outcomes for women with co-occurring disorders and trauma: program-level effects

Area of Science:

• Psychiatry
• Psychology
• Public Health

Background:

• Women with mental health problems, substance use disorders, and histories of interpersonal violence face complex, intersecting challenges.
• Existing services may not adequately address the multifaceted needs of this population.
• Trauma-informed, consumer-involved approaches are increasingly recognized as crucial for effective care.

Purpose of the Study:

• To evaluate the program-level effects of a comprehensive, integrated, trauma-informed, and consumer-involved service model.
• To identify program-level factors that explain heterogeneity in treatment outcomes.
• To assess the impact on post-traumatic symptoms, drug use problem severity, and mental health symptoms at 6 months.

Main Methods:

• Meta-analysis of a nine-site quasi-experimental study.
• Assessment of program-level effects at 6-month follow-up.
• Examination of program-level variables to explain heterogeneity in effect sizes.

Main Results:

• Significant improvements observed in post-traumatic symptoms (p < 0.02) and drug use problem severity (p < 0.02).
• Mental health symptoms showed a nearly significant improvement (p < 0.06).
• Higher levels of integrated counseling were associated with significantly better mental health symptoms (p < 0.01) and reduced alcohol (p < 0.001) and drug use problem severity (p < 0.001).

Conclusions:

• The integrated service model demonstrates effectiveness in addressing complex needs of women with co-occurring disorders and trauma histories.
• Service integration, particularly counseling integration, is a key factor in achieving better outcomes.
• Further research is warranted to optimize service delivery and address remaining heterogeneity.
