This uncontrolled pilot interventional study will examine the feasibility and preliminary efficacy of RESTORE. RESTORE is a guided self-directed online intervention to improve anxiety, depression, and posttraumatic stress disorder (PTSD) in individuals exposed to COVID-19 related traumatic or extreme stressors. RESTORE is based on evidence-based psychotherapies and has been designed to overcome many of the barriers associated with accessing evidence-based psychotherapies. The intervention will be iteratively refined over the course of the study. The guidance methods will also be refined and manualized over the course of the study~The primary hypotheses are that RESTORE will be safe, feasible, and desirable to participants, and will lead to improvements in mental health symptom severity from baseline to post-intervention. Secondary hypotheses are that RESTORE will lead to significant improvements in perceived health, quality of life, and functioning from baseline to post-intervention. Participants will be assessed at baseline, pre-intervention, during the intervention (after module 4), immediately after the intervention, and 1 month after completion of the intervention.
There is considerable need for psychological intervention targeting stressor-related mental health symptoms related to COVID-19. The investigators have developed an online self-directed transdiagnostic intervention to address this need called RESTORE: Recovering from Extreme Stressors Through Online Resources and E-health. The specific aims of this project are to refine and investigate the feasibility, initial safety, and efficacy of RESTORE for addressing mental health symptoms in first responders, health care workers (HCW), and Canadian Armed Forces members exposed to COVID-19-related traumatic or extreme stressors.
