Spring is an online guided self-help programme for the reduction of posttraumatic stress disorder symptoms. It is based on the principles of trauma-focused cognitive behavioral therapy and consists of 8 steps covering psychoeducation, grounding techniques, management of anxiety, behavioral activation, imaginal exposure, cognitive restructuring, in vivo exposure, and prevention of relapse. The user of the programme also receives up to 3 hours of therapist guidance. Originally Spring was developed by the research team at Cardiff University. In the current study, the most recent second version of the Spring programme adapted to the Lithuanian population will be used. The main aim of the study is to evaluate the efficacy of the Lithuanian version of the Spring programme in reducing ICD-11 posttraumatic stress disorder symptoms.
