The UCLA hoarding severity scale: Development and validation
Open accessAbstract
Background Effective management of Hoarding Disorder (HD) must begin with assessment of the severity of hoarding symptoms and functional impairment. We sought to validate the UCLA Hoarding Severity Scale (UHSS), a semi-structured, clinician-administered rating scale that measures the severity of both the core symptoms of HD and the associated features of indecisiveness, perfectionism, task prolongation, and procrastination, which are significantly associated with the diagnosis and impairment of HD.Methods Hoarding symptom severity was measured in 62 patients who met DSM-5 diagnostic criteria for HD and 65 normal controls, using the UHSS and the Saving Inventory-Revised (SI-R), a well validated self-report measure of hoarding symptoms.Results The UHSS showed significant internal consistency (Cronbach׳s α=.70). Principal components analysis revealed three factors that accounted for 58% of the variance: 1) associated features and functional impairment, 2) clutter volume and social impairment, and 3) difficulty discarding, urges to save, and excessive acquisition. UHSS and SI-R scores were significantly correlated. UHSS and SI-R total and factor scores of HD patients were all significantly different from those of controls.Limitations Inter-rater and test-retest reliability were not assessed. The initial version of the UHSS did not contain rater instructions, so it lacked quantifiable anchor points for ratings.Conclusions The UHSS showed internal consistency, construct validity, convergent validity, and known groups discriminant validity. The UHSS validly measures the core symptoms, associated features, and functional impairment of patients with HD. Utilizing a valid clinician-administered scale will provide a more comprehensive and accurate clinical assessment of patients with HD.

All participants met DSM-5 criteria for hoarding disorder, established by clinical interview and scores on the UHSS and SI-R.
“All participants were required to meet DSM-5 criteria for HD, determined using a clinical interview in conjunction with scores on the UCLA Hoarding Severity Scale (UHSS; Saxena, Ayers, Dozier, & Maidment, 2015), a 10-items clinician-administered assessment, and on the Savings Inventory- Revised (SI-R; Frost et al., 2004), a 23-item self-report measure.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
