Eksperimentel: Reinforced Prolonged Exposure (RPE)
All participants will be scheduled to attend a weekly Prolonged Exposure therapy session for 12 consecutive weeks, and followed for 12 additional weeks.
RPE participants will receive voucher-based reinforcement contingent on attendance to scheduled Prolonged Exposure therapy sessions.

Prolonged Exposure Therapy is considered the "gold standard" treatment for PTSD in psychiatry.
It uses a cognitive-behavioral approach that repeatedly and systematically exposes patients to memories of their traumatic events to reduce fear and arousal.
The PE therapy offered in this study will be based on procedures used by Foa and colleagues, described in their book-length treatment manual (Foa, Hembree, & Rothbaum, 2007).
Andre navne:
Those in the PE+CM condition will also be able to earn voucher-based incentives for each therapy session that they attend as scheduled, with a maximum of $480 for full adherence to all sessions.
Specifically, participants will earn $30 for attending Session 1, $40 for attending Session 2, $50 for attending Session 3, and $60 for attending Sessions 4 through 9.
There will be no payment for Sessions 10 through 12.
Because it is very important that participants attend sessions on schedule, voucher values will be reset starting from $30 if participants miss a scheduled session.
Vouchers can be exchanged for goods and services in the community (e.g., gift cards to local retailers).
