Abstract
The aim of this randomized controlled trial was to investigate the effects of guided internet-based cognitive be-havior therapy (ICBT) for posttraumatic stress disorder (PTSD). Sixty-two participants with chronic PTSD, asassessed by the Clinician-administered PTSD Scale, were recruited via nationwide advertising and randomizedto either treatment (n= 31) or delayed treatment attention control (n= 31). The ICBT treatment consisted of8 weekly text-based modules containing psychoeducation, breathing retraining, imaginal and in vivo exposure,cognitive restructuring, and relapse prevention. Therapist support and feedback on homework assignmentwere given weekly via an online contact handling system. Assessments were made at baseline,... (More)

Sixty-two participants with chronic PTSD, asassessed by the Clinician-administered PTSD Scale, were recruited via nationwide advertising and randomizedto either treatment (n= 31) or delayed treatment attention control (n= 31). The ICBT treatment consisted of8 weekly text-based modules containing psychoeducation, breathing retraining, imaginal and in vivo exposure,cognitive restructuring, and relapse prevention. Therapist support and feedback on homework assignmentwere given weekly via an online contact handling system. Assessments were made at baseline, post-treatment,and at1-yearfollow-up.Mainoutcomemeasures were theImpact of Events Scale—Revised(IES-R)and the Post-traumatic Stress Diagnostic Scale (PDS). Results showed significant reductions of PTSD symptoms (betweengroup effect on the IES-R Cohen'sd= 1.25, andd= 1.24 for the PDS) compared to the control group. Therewere also effects on depression symptoms, anxiety symptoms, and quality of life. The results at one-yearfollow-up showed that treatment gains were maintained. In sum, these results suggest that ICBT with therapistsupport can reduce PTSD symptoms significantly.
