Using latent patient-centered fear extinction profiles to guide treatment in pediatric OCD.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundWhile exposure with response prevention (ERP) is the frontline treatment for pediatric obsessive-compulsive disorder (OCD), not all patients benefit. Impairments in extinction learning are implicated in pediatric OCD's etiology and treatment, with impaired pre-treatment extinction learning associated with worse ERP outcomes. However, available methods for assessing patients' difficulties with fear extinction are costly and underdeveloped. In response, we used person-centered profiles to characterize latent fear extinction patterns among youth with OCD, and investigated the degree to which scores on common rating scales correspond to profile membership.
methodsYouth with OCD (n=98) completed a diagnostic clinical battery followed by a differential fear conditioning/extinction task, in which skin conductance response (SCR) to stimuli served as the primary outcome. Parallel process growth mixture modeling (i.e., person-centered trends in concurrent change over time SCR to differential stimuli) was used to illuminate latent profiles of fear conditioning/extinction processes. The Bose-Chaudhuri-Hocquenghem method compared latent classes to identify clinical correlates of impaired extinction.
resultsA 2-profile solution was retained. Profile 1 (85%) was characterized by typical patterns of fear acquisition and extinction learning. Profile 2 (15%) exhibited elevated levels of SCR and impairments in threat discrimination during extinction. Several items on anxiety and OCD rating scales were significantly different between profiles.
conclusionsFindings identified two distinct profiles in how youth with OCD responded to a fear extinction task, with one demonstrating substantial difficulty. Future directions should examine the extent to which impaired fear extinction ability inhibits ERP effectiveness, and consider utilizing patient-centered profiles as an initial prognostic indicator of ERP appropriateness.
