Towards a Clinically Valid Mechanistic Assessment of Exposure and Response Prevention: Preliminary Utility of an Exposure Learning Tool for Children with OCD.

Despite advances in understanding mechanisms underlying fear processes, there remains a significant gap between insights produced via laboratory assessment and concrete tools for harnessing these insights in clinical practice. In addressing this gap, researchers would ideally introduce tools that are feasible for patients in clinical practice, easily disseminated to practitioners, and clinically useful. We present pilot data on the Exposure Experience Questionnaire (EEQ), a brief measure designed to assess exposure learning mechanisms. Ten children (ages 8-15) with a primary diagnosis of obsessive-compulsive disorder (OCD) underwent exposure and response prevention in which they completed weekly exposures in clinic and at home. During each exposure, children completed an exposure practice form which included the EEQ. Results suggest the preliminary feasibility and internal consistency of this measure, with comparable utility in clinic and home settings. The EEQ was associated in the expected direction with slope of OCD symptoms, such that greater exposure learning in both clinic and homework exposures predicted improved outcome. Although limited by small sample size, these data support the continued research on the feasibility and utility of the EEQ and suggest that quantifying learning processes following exposure may be a useful addition to mechanistic research in OCD.
