Families with a child on the waitlist for trauma-focused services will be invited to participate. Participation involves completing a baseline assessment of family functioning and trauma characteristics. Participants will then be randomized to either Project Support or the treatment as usual control group. All participants will be invited to complete the post-test assessment 4-6 weeks after the baseline assessment, prior to beginning trauma-focused services.
