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.
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.
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.
The SI-R can be used to validly assess hoarding severity in geriatric populations.
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.
囤积障碍（HD）是一种慢性病，其特征是对老年人的健康和功能造成严重损害。研究人员和临床医生通常使用修订版储蓄量表（SI-R）来确定症状严重程度，该量表是一种经过验证的用于评估囤积障碍的自我报告测量工具。本研究首次对患有囤积障碍的老年样本中SI-R的心理测量特性进行了评估。
参与者包括156名患有囤积障碍的老年人和23名无精神疾病诊断的老年人。比较了两个样本的人口统计学和囤积障碍症状严重程度测量结果。在囤积障碍样本中检验了聚合效度和区分效度。使用验证性因素分析来检验在原始样本中观察到的三因素结构的可重复性。
囤积障碍样本中的参与者在SI-R上的得分显著高于非精神疾病样本。SI-R与杂乱程度以及焦虑和抑郁症状显著相关。三因素模型在囤积障碍样本中拟合不佳。
SI-R可用于有效评估老年人群中的囤积严重程度。
治疗老年患者的临床医生应考虑避免使用SI-R分量表，因为它们在老年人中可能在理论上区分度较低。
