Separate research has evaluated trajectories of posttraumatic stress symptoms (PTSS) and obsessive-compulsive symptoms (OCS), but no study has evaluated OCS trajectories following trauma exposure nor combined PTSS/OCS trajectories. The present study evaluated combined PTSS/OCS trajectories among 585 survivors of Hurricane Helene, spanning three waves of data collection over 12 months. A 3-class solution was supported, including resilient (i.e., consistently low PTSS and OCS), chronic (i.e., elevated PTSS and OCS with gradual reduction over time), and moderate-yet-diverging (i.e., moderate elevations in PTSS and OCS with gradually declining PTSS and persistent and increasing OCS over time) classes. This study shows both overlap and differentiation in symptom trajectories from earlier research, with the moderate-yet-diverging trajectory suggesting unique OCS pathways distinct from PTSS.
