Abstract

ABSTRACT: Objectives : Hoarding disorder (HD) is a chronic condition characterized by severe impairment in health and functioning for older adults. Researchers and clinicians commonly use the Saving Inventory-Revised (SI-R), a self-report measure validated for the assessment of HD, to establish symptom severity. This study represents the first evaluation of the psychometric properties of the SI-R in a sample of older adults with HD. Methods : Participants were 156 older adults with HD and 23 older adults with no psychiatric diagnoses. Demographic and HD symptom severity measures were compared between the two samples. Convergent and discriminant validity was examined in the HD sample. A confirmatory factor analysis was used to test the replicability of the three-factor structure observed in the original sample. Results : Participants in the HD sample scored significantly higher on the SI-R than did the non-psychiatric sample. The SI-R was significantly correlated with clutter level and symptoms of anxiety and depression. A three-factor model demonstrated poor fit in the HD sample. Conclusions : The SI-R can be used to validly assess hoarding severity in geriatric populations.Clinical Implications : Clinicians working with geriatric patients should consider refraining from use of the SI-R subscales as they may be less theoretically distinct in older adults.
