© 2019 Elsevier Inc. The Hoarding Disorder-Dimensional Scale (HD-D) is a new measure of hoarding symptom severity developed by the Diagnostic and Statistical Manual (5th Edition) Obsessive-Compulsive Spectrum Disorders Sub-workgroup. The aim of the current study was to assess the psychometric properties of this measure in a large, community sample. Five hundred and seventeen participants completed the study. The results indicated that the HD-D consists of a single factor accounting for 66% of the variance. The measure demonstrated high internal consistency (α = 0.87–0.88) and test-retest reliability (r = 0.84). The HD-D also demonstrated good convergent and divergent validity in this sample. There appeared to be good convergence between internet and paper and pencil formats of the HD-D (r = 0.88). Overall, the results indicate that the HD-D demonstrates sound psychometric properties in a community sample.
