Outcome Measures

Primary Outcomes (2)

• Saving Inventory-Revised (SI-R)

  The SI-R is a 23-item questionnaire with 3 sub-scales: 1) difficulty discarding, 2) excessive clutter, and 3) excessive acquisition.

  Change from baseline (week 0) to post-treatment (week 10),

• Clutter Image Rating Scale (CIR)

  Three sets of photographs, each comprising 9 photos of a room with varying levels of clutter. A selection is made as to which photograph best resembles the room of the participant.

  Change from baseline (week 0) to post-treatment (week 10).

Study Arms (2)

In-home decluttering

EXPERIMENTAL

Study participants receive weekly sessions of in-home decluttering for 10 weeks.

Behavioral: In-home decluttering practice

Delayed treatment

NO INTERVENTION

Study participants receive weekly session of in-home decluttering after a 10 week delay.

Interventions

In-home decluttering practice BEHAVIORAL

The in-home decluttering intervention comprises 10, 1.5-hour home-visits over the course of 10 weeks. These home visits are personalized, goal-oriented and focused on decluttering. They include 1) a brief check-in, 2) guided unclutter time 3) a reflective period during which participants share their thoughts and objectives for the coming week, and 4) homework assignments.
