Abstract
BACKGROUND Hoarding disorder (HD) affects approximately 2.5% of the general population, leads to significant distress and impairment, and is notoriously difficult to treat. The crux of developing effective treatments for HD is our ability to reliably and validly measure relevant constructs in HD to better understand its presentation and, subsequently, formulate appropriate interventions. METHODS We identified measures specific to HD and evaluated their psychometric properties using rating criteria formulated by the Consensus-based Standards for the selection of health Measurement INstruments (COSMIN) group. RESULTS The 17 included measures were developed to assess adult and pediatric hoarding severity, functional impairment, and maladaptive processes (e.g., material scrupulosity). The Saving Inventory-Revised, the most widely used measure of HD severity showed the strongest psychometric properties. However, psychometric investigations were generally of poor quality across all measures and results indicated unsatisfactory performance of measures. LIMITATIONS The current review excluded non-English measures and ratings inherently contain some element of subjectivity despite use of predetermined criteria and two independent reviewers. CONCLUSIONS We suggest that clinical researchers continue to develop and modify measures used to conceptualize and, ultimately, improve treatment for HD.

Abstract
Executive functions (EF) deficits are hypothesized to be a core contributor to hoarding symptoms. EF have been studied in adult hoarding populations, but studies in youth are lacking. The current study compared multiple EF subdomains between youth with obsessive-compulsive disorder (OCD) and youth with OCD and hoarding symptoms. Forty youth (8-18 years old) with a primary diagnosis of OCD were recruited. Participants were divided by hoarding severity on the Child Saving Inventory (CSI) into either the "hoarding group" (upper 33.3%) or the "low-hoarding group" (lower 66.7%). Groups were compared on EF tasks of cognitive flexibility, decision-making, and inhibitory control. Youth in the hoarding group exhibited significantly higher cognitive flexibility and lowered perseveration than the low-hoarding group. Hoarding and low-hoarding groups did not differ in any other EF subdomain. Hoarding symptoms in youth with OCD were not associated with deficits in EF subdomains; instead, youth who hoard exhibited higher cognitive flexibility compared to youth with low hoarding symptoms.
