Clutter Image Rating

Functionality & Mechanism

The Clutter Image Rating (CIR) is a validated pictorial instrument designed for the standardized assessment of home clutter. The system presents a series of nine equidistant photographs for three distinct rooms: the kitchen, living room, and bedroom. Each series visually depicts a clutter severity continuum from 1 (uncluttered) to 9 (severely cluttered). The interface captures a rating for each room by prompting the selection of the image that most accurately represents the environment, facilitating objective measurement and progress monitoring.

Evidence & Research Context

• Two validation studies established the psychometric properties of the CIR in both mid-life and geriatric adult populations diagnosed with hoarding disorder.
• The scale demonstrates robust internal consistency, test-retest reliability, and inter-observer reliability for rating clutter severity.
• Validation analyses confirmed strong convergent validity with established questionnaire and interview measures of clutter.
• The instrument shows strong divergent validity, correlating more significantly with clutter-specific measures than with other hoarding symptoms or general psychopathology scales.

Intended Use & Scope

This instrument is designed for clinicians, researchers, and human service professionals to conduct rapid, standardized assessments of clutter. Its primary utility is as a screening and progress-monitoring tool within a comprehensive clinical evaluation. The CIR assesses the single dimension of clutter and does not serve as a standalone diagnostic instrument for hoarding disorder; professional interpretation is required.
