The Trauma Recovery and Empowerment Model: A Quasi-Experimental Effectiveness Study.

Area of Science:

• Psychiatry
• Psychology
• Trauma Studies

Background:

• Trauma survivors with co-occurring mental illnesses and substance use disorders often require specialized interventions.
• The Trauma Recovery and Empowerment Model (TREM) is a group intervention designed for women trauma survivors.

Purpose of the Study:

• To test the effectiveness of the TREM intervention compared to services as usual for women trauma survivors with co-occurring disorders.
• To evaluate changes in substance abuse, mental health symptoms, quality of life, and perceived safety.

Main Methods:

• A quasi-experimental design involving 251 women with histories of abuse and co-occurring disorders.
• Intervention group (n=153) received TREM plus usual services; comparison group (n=98) received usual services.
• Data collected at baseline, 6 months, and 12 months.

Main Results:

• TREM participants demonstrated greater reductions in alcohol and drug abuse severity, anxiety, and stressful events.
• TREM participants reported increased perceived personal safety.
• No significant group differences were found for PTSD, global mental health, quality of life, or interpersonal abuse exposure.

Conclusions:

• The TREM intervention shows preliminary evidence of effectiveness for a diverse group of women trauma survivors with co-occurring disorders.
• TREM, when added to usual services, may offer benefits for specific outcomes like substance abuse and anxiety.
• Further research is warranted to confirm these findings and explore mechanisms of change.
