Disseminating evidence-based practices for adults with PTSD and severe mental illness in public-sector mental health agencies.

Frueh et al. (2009) looked at how to move proven trauma therapies into busy public mental-health clinics.

They wrote a roadmap that mixes staff training, weekly supervision, fidelity checks, and clear accountability.

The focus is adults who carry both PTSD and severe mental illness, a group that often gets bounced between programs.

The paper does not give new outcome numbers.

Instead it lists the exact steps an agency needs so therapists keep using the trauma tools after the workshop ends.

Aller et al. (2023) tested one of these trauma tools—plain-language Narrative Exposure Therapy—in adults with severe illness and saw big PTSD drops.

That study shows the 2009 roadmap can lead to real client gains when a clinic actually follows through.

Novak et al. (2019) fills in the training details the roadmap only sketched: use behavioral skills training up front, then keep giving coaching and feedback.

Vroom et al. (2022) pushes the idea further, telling leaders to stop waiting for perfect studies and start building the agency systems Christopher’s team outlined.

If you supervise in a community clinic, you can copy the four-part plan: pick one trauma model, train with role-play, track fidelity each month, and tie continued funding to correct use.

Start small—one team, one supervisor—and add the other teams once the paperwork feels routine.
