Abstract
Obsessive-compulsive and related disorders (OCRDs) and disorders due to addictive behavior (DABs) are prevalent conditions that share common neurobiological and behavioral characteristics. This scoping review aims to identify and map the range of subjective assessment tools (e.g., interviews and self-report instruments) for assessing Research Domain Criteria (RDoC) and related constructs underlying DABs and OCRDs, such as impaired response inhibition, habit formation, and compulsivity. A scoping review was performed following the PRISMA Extension for Scoping Reviews (PRISMA ScR). The search was conducted in Medline, Web of Science, PsycINFO, and EMBASE databases. No constraints of data or document type were adopted. The search yielded 615 instruments, of which 79 were deemed transdiagnostic and capable of assessing at least one of the target constructs. Noteworthy tools included are the Cambridge-Chicago Compulsivity Trait Scale, the Self-report Habit Index, the Reward Probability Index, the Threat-Related Reassurance-Seeking Scale, and the recent Positive Valence Systems Scale. Despite the growing body of literature on OCRDs and DABs as new diagnostic chapters and the number of tools with the potential to assess their transdiagnostic constructs clinically, most instruments were designed to capture dimensions or psychopathology not directly (or primarily) related to OCRDs, DABs and the concepts of impaired response inhibition, habit formation, and compulsivity in the context of these conditions. Further studies exploring the correlation between subjective assessments, corresponding behavior paradigms, and neuroimaging data would be of great value in the translation of RDoC constructs and domains into clinical settings.
