Saving inventory – Revised: Psychometric performance across the lifespan

Abstract

Background: The Saving Inventory-Revised (SI-R) is the most widely used self-report measure of hoarding symptom severity. The goal of this study is to establish a firm empirical basis for a cutoff score on the SIR and to examine the functioning of the SIR as a screening tool and indicator of hoarding symptom severity across the lifespan. Methods: This study used archival data from 1,116 participants diagnosed with a clinical interview in 14 studies conducted by research groups who focus on hoarding. We used receiver operating characteristic (ROC) analysis and the Youden's Jstatistic to determine optimal cutoff scores for classifying participants who would be likely to receive a hoarding diagnosis. Results: Overall, the discriminant performance of the SIR Total score and each of the three subscales was high, confirming the status of the SIR is an excellent screening tool for differentiating hoarding from non-hoarding cases. The optimal SIR Total cutoff score is 39, although analyses suggested that older adults require a significantly lower cutoff and adults younger than 40 years require a significantly higher cutoff score. Limitations: The confidence interval around the optimal cutoff for the SIR Total score for oldest age group was wide in comparison to those reported for the younger groups, creating more uncertainty around the optimal cutoff score for this group. Conclusions: This paper provides investigators and clinicians with the data necessary to select evidence-based cutoff scores on the SIR that optimally suit their relative need for sensitivity and specificity in different age groups.

Treatment outcomes in older adults with hoarding disorder: The impact of self‐control, boredom and social support

“…The level of improvement in the current study is comparable to what has been observed with CBT in other studies with older patients 20 . However, it is important to note that less than half of the sample demonstrated clinically significant change, and the median post‐treatment SI‐R score remained above the recommended clinical cut‐off for older adults 21 . This suggests that many participants continued to experience considerable levels of distress and impairment and indicates a need for further treatment.…”

Moreover, several limitations must be taken into account when interpreting the results, most notably, the unusually high attrition rate.…”

Investigating associations between hoarding symptoms and affective and cognitive empathy

“…A final set of analyses were conducted to examine TASIT-S performance of the subgroup of participants in the current sample who reported clinically significant hoarding symptoms (SIR > 39; Kellman-McFarlane et al, 2019). Participants within the subgroup ranged in age from 21.86 to 72.02 years old, with the mean age being 33.76 years old.…”

“…After controlling for depression, performance on TASIT 2 was a unique individual predictor of hoarding symptoms, b = À.580, t(273) = À2.766, p < .01. TASIT-S scores for individuals who had clinically significant hoarding symptoms (i.e., SIR scores > 39; Kellman-McFarlane et al, 2019) were compared to the normative data. This subgroup of participants showed moderate impairment in TASIT 1: emotion recognition (z = À2.17).…”

Traumatic and stressful life events in hoarding: the role of loss and deprivation

“…Total scores vary from 0 to 92. Recently, a score of 39 was proposed as the optimal cut-off to differentiate people with problematic from nonproblematic hoarding symptoms (Kellman-McFarlane et al, 2019).…”
