Clutter Image Rating Scale

What Is the Clutter Image Rating Scale?

The Clutter Image Rating Scale (CIRS) is a standardized visual assessment tool developed by researchers at the Institute for Living and Hartford Hospital. It uses a series of photographs depicting rooms at varying levels of clutter to help individuals, therapists, and other professionals objectively measure how cluttered a living space is. The scale provides a common language for describing clutter severity and is one of the most widely used assessment instruments in hoarding research and clinical practice.

The CIRS was designed to overcome a fundamental challenge in hoarding assessment: people with hoarding disorder often have difficulty accurately describing or recognizing the severity of their clutter. By using visual comparisons rather than verbal descriptions, the CIRS reduces subjectivity and provides a more reliable baseline for evaluating progress over time.

How the Scale Works

The CIRS presents nine photographs for each of three rooms — the living room, kitchen, and bedroom. Each set of nine images shows the same room at progressively increasing levels of clutter, from completely clear (rated 1) to extremely cluttered with virtually no visible floor or surface space (rated 9). The individual being assessed selects the photograph that most closely matches the current state of each room in their home.

The rating breakdown is generally understood as follows:

• 1-2: Minimal to no clutter. The room is tidy with clear surfaces and open floor space. This is within the range of normal household organization.
• 3-4: Mild clutter. Surfaces are partially covered and some items are on the floor, but the room remains functional and pathways are clear.
• 5-6: Moderate clutter. Significant portions of surfaces and floor space are occupied by items. Furniture may be partially buried, and navigating the room requires some effort.
• 7-8: Severe clutter. Most surfaces and large portions of the floor are covered. The room is difficult to use for its intended purpose, and movement is restricted to narrow pathways.
• 9: Extreme clutter. Virtually every surface and the entire floor is covered. The room is completely unusable, and entry may be difficult or impossible.

A composite score is typically calculated by averaging the ratings across all three rooms. Scores of 4 or above generally indicate clinically significant clutter that may warrant professional intervention.

Who Uses the CIRS?

The Clutter Image Rating Scale is used by a range of professionals involved in hoarding assessment and treatment:

• Therapists and psychologists use the CIRS during initial assessment to establish a baseline and during treatment to measure progress in therapy sessions focused on hoarding behavior.
• Social workers use the scale during home visits to document living conditions, particularly in cases involving vulnerable adults, children, or individuals receiving government assistance.
• Hoarding cleanup professionals reference the CIRS to estimate the scope of work and provide accurate cost estimates before beginning a project.
• Code enforcement and health inspectors may use the CIRS as a standardized documentation tool when evaluating properties for violations.
• Researchers rely on the CIRS to study hoarding prevalence, treatment outcomes, and the effectiveness of various interventions.

CIRS vs. Other Assessment Methods

The CIRS is one of several tools used to assess hoarding severity. Other common instruments include the Saving Inventory-Revised (SI-R), which measures acquisition, difficulty discarding, and clutter through a questionnaire, and the Hoarding Rating Scale (HRS), a brief five-item interview-based tool. The CIRS is unique in its visual approach, which makes it particularly useful for individuals who may underreport their clutter severity in verbal or written assessments.

Many clinicians use the CIRS in combination with questionnaire-based tools to get the most complete picture of hoarding severity. The visual format also makes the CIRS more accessible to individuals with limited literacy or those for whom English is a second language.

Taking a Self-Assessment

While a professional evaluation provides the most reliable results, self-assessment can be a valuable first step. If you are concerned about clutter levels in your home or the home of a loved one, our hoarding assessment tool can help you evaluate severity and determine whether professional help may be beneficial. Self-assessment is most useful when approached honestly and without judgment — the goal is not to assign blame but to understand the current situation and identify the best path forward.
