Objective:
To investigate the differential effects of an internet-based cognitive-behavioral writing therapy (iCBT) on post-traumatic stress disorder (PTSD) symptoms after intensive care in patients and their spouses.
Methods:
This reanalysis of a randomized controlled trial compared PTSD symptom severity (measured by PCL-5) before and after therapy considering potential influencing factors in the per-protocol population.
Results:
A significant reduction in post-traumatic symptom severity after iCBT was found. Eleven of the 25 treated participants showed a clinically significant change (PCL-5 difference≥10 points). The number of words written by the participants in the therapy modules had a significant impact on iCBT efficacy.
Conclusion:
iCBT appears to be a promising option to augment therapy for PTSD, particularly for physically impaired patients following critical illness.
