Abstract

A recent study identified three distinct treatment-response trajectories in pediatric OCD where higher levels of contamination symptoms predicted a limited response to cognitive-behavioral therapy (CBT). This study extends these findings by examining which specific symptoms characterize limited CBT response from baseline to 3-year follow-up, with an emphasis on contamination symptoms. The study sample comprised 269 pediatric patients with OCD, all receiving stepped-care treatment with manualized CBT. Differences in single item-reporting between the three trajectory groups were examined using linear mixed-effect modeling. Limited responders displayed a higher symptom load across all OCD symptom categories at 3-year follow-up, dominated by contamination symptoms. Five of these (obsessions about dirt and germs, about bodily fluids, about the feeling of contamination and compulsions regarding handwashing and showering) showed persistence from baseline to 3-year follow-up. The results indicate that presence of specific contamination symptoms may influence long-term symptom severity trajectories in young patients with OCD.
