Abstract

BackgroundThe Clutter Image Rating (CIR) Scale though extensively used to assess hoarding behavior, has mainly been validated in Western populations.MethodsThe current study sought to validate the CIR in a sample of psychiatric outpatients (n = 500) in Singapore. Convergent and divergent validity as well as inter-observer reliabilities between participant CIR and interviewer-rated CIR were calculated.ResultsThe CIR performed fairly in identifying participants with and without hoarding problems according to the Savings Inventory Revised (SI-R). The CIR composite demonstrated good convergent validity with the SI-R clutter subscale, the SI-R total and the Activities of Daily Living Scale for Hoarding (ADL-H) scale and discriminant validity with the Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI), and Quality of Life Enjoyment and Satisfaction Questionnaire – Short Form (Q-LES-Q-SF) scale.ConclusionsFindings add valuable knowledge to the utility of the CIR in an Asian population.

Highlights

The Clutter Image Rating (CIR) Scale though extensively used to assess hoarding behavior, has mainly been validated in Western populations
Classification of hoarding status As the presence of clinically significant hoarding problems was not a prerequisite for our study, the Saving Inventory - Revised (SI-R) scores were used as a reference to understand the hoarding characteristics in our sample
It was previously established that a cutoff score of 41 or higher on the SI-R would indicate clinically significant hoarding symptoms [30]

Summary

Introduction

The Clutter Image Rating (CIR) Scale though extensively used to assess hoarding behavior, has mainly been validated in Western populations. Several instruments have been developed to assess the severity of hoarding symptoms and associated functional impairment [9, 16] These include self-report questionnaires such as the Saving Inventory - Revised (SI-R) [17] which examines the three main domains of hoarding behavior: difficulty discarding, excessive clutter, and excessive acquisition, the Sagayadevan et al BMC Psychiatry (2016) 16:407. Others include semistructured interviews such as the Hoarding Rating Scale-Interview (HRS-I) [19] which assesses the three main features of hoarding (clutter, difficulty discarding, and excessive acquisition) as well as the distress and interference caused by the hoarding behavior
