Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Cognitive behavioral therapy (CBT) is the current evidence-based treatment for HD but the majority of sufferers remain symptomatic after CBT with impairing levels of clutter in their homes. Home visits, with a focus on in-home decluttering, have in previous research been shown to be a promising intervention when combined with CBT. However, augmenting CBT with subsequent home visits has not yet been tested in a randomized controlled trial (RCT). In response to this, in this trial, we aim to investigate the efficacy of a coordinated intervention, consisting of CBT and in-home decluttering for HD, in an RCT. In this trial, 90 participants with HD will initially receive 12 sessions of CBT through a psychiatric outpatient service. After CBT, participants will be randomized to receive either 10 home visits in 10 weeks, or to a wait list condition. Our hypothesis is that augmenting CBT with home visits will lead to a reduction in hoarding symptoms and clutter and improved daily functioning compared to wait list. We will also investigate the cost-economical aspects of the intervention. Results from this trial have the potential to reveal whether in-home decluttering should be added to CBT in order to reduce symptoms of hoarding and improve function in indviduals with HD.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

In-home decluttering

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

Group Type EXPERIMENTAL

In-home decluttering practice

Intervention Type 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.

Delayed treatment

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

Group Type NO_INTERVENTION
