Background: Victims of violent crime are at elevated risk of developing acute stress disorder (ASD) as well as subsequent post-traumatic stress disorder (PTSD), both of which are linked to severe psychological distress. The aim of this 12-month prospective study was to evaluate the efficacy of cognitive-behavioral therapy (CBT) vs. cognitive-behavioral therapy with a significant other (CBT-SO), relative to usual care (UC), for the improvement of post-traumatic, depression and anxiety symptoms and the prevention of PTSD among victims of violent crime with ASD.
Methods: A total of 166 victims of violent crime with ASD were assigned to CBT (n = 54), CBT-SO (n = 52) or UC (n = 60). Self-report assessments and diagnostic interviews were completed at pre-treatment and post-treatment as well as at 6-month and 12-month follow-ups.
Results: CBT and CBT-SO participants had fewer depression symptoms than those in the UC group up to 12 months post-event. Significantly fewer participants in the CBT condition met criteria for PTSD than in the UC group up to 12 months post-event. The CBT group did not differ from the CBT-SO group on any variable at any assessment time.
Limitations: Findings must be interpreted in light of the quasi-experimental nature of the study and limitations concerning the management of missing data.
Conclusions: Further research is warranted in order to assess whether more extensive involvement of a significant other in therapy may lead to better outcomes for victims of violent crime with ASD.
