简要总结
The primary aim of trial is to determine the clinical efficacy of in-home decluttering augmentation of group CBT for reducing hoarding severity in adults with HD. The trial takes place in Sweden.
详细描述
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.

研究组 & 干预措施
In-home decluttering
Study participants receive weekly sessions of in-home decluttering for 10 weeks.
干预措施: In-home decluttering practice (Behavioral)
Delayed treatment
Study participants receive weekly session of in-home decluttering after a 10 week delay.
结局指标
主要结局
Saving Inventory-Revised (SI-R)
时间窗: Change from baseline (week 0) to post-treatment (week 10),
The SI-R is a 23-item questionnaire with 3 sub-scales: 1) difficulty discarding, 2) excessive clutter, and 3) excessive acquisition.
Clutter Image Rating Scale (CIR)
时间窗: Change from baseline (week 0) to post-treatment (week 10).
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.
