Summary
Brief summary
The study has several aims: (1) to test whether cognitive processing therapy (CPT) is helpful after recent trauma; (2) to test that CPT is as good as the usual therapy delivered in the sexual assault service (treatment as usual, TAU); (3) to ensure that counsellors not previously trained in CPT can learn and deliver the therapy with the same results as previous studies that have used highly experienced and trained cognitive behavioural therapists. We predict that CPT will be useful in reducing posttraumatic stress, that it will be at a minimum as good as treatment as usual, and we hypothesise that CPT therapists will show results comparable to previous treatment outcome studies using CPT.
