After being informed about the study potential risks, all patients giving written informed consent will undergo screening to determine eligibility for study entry. They will be randomly assigned to one of four conditions (Imagery rescripting past; Imagery rescripting future; Imaginal exposure past; Imaginal exposure future) at a 1:1:1:1 ratio (n = 115 per group). Participant will be assigned using a variance minimization method that controls for between group variance in continuous and categorical variables- SPIN, ASI-3, OCI-R, GAD-7 and gender with a completely random assignment p random = .2 (for algorithm see Sella et al., 2018). Participants will attend three \~1.5 hour online ZOOM sessions (baseline-assessment and measurement, intervention, post assessment and measurement and follow-up measurement).
In this multiple baseline study, participant will enter the intervention phase either 7 or 14 days after the baseline stage.
Assessors will be blind to the treatment condition.
