The investigators will investigate internet delivered prolonged exposure delivered as a ten-week treatment comprising of six modules (psychoeducation/rational, in vivo exposure, imaginal exposure, common problems during exposure, hot spots and relapse prevention). The feasibility and acceptability and preliminary effects of treatment- and assessment procedures will be evaluated using a within-group design with repeated measurements and qualitative interviews. Recruitment is designed to be broadly inclusive with minimal exclusion criteria. Patients will be recruited from a psychiatric clinic specialized in PTSD in Stockholm, Sweden and by advertisements in newspapers and social media.
The primary objective with this study is to investigate the feasibility and acceptability of ten weeks of internet delivered prolonged exposure delivered through a digital platform with therapist support. The secondary objective is to investigate preliminary effects of internet delivered prolonged exposure in terms of reducing symptoms of post-traumatic stress, depression and increase quality of life.
