What this trial studies

This trial aims to evaluate the effectiveness of combining in-home decluttering assistance with group cognitive behavioral therapy (CBT) for adults suffering from hoarding disorder (HD). Participants will first undergo 12 sessions of CBT, after which they will be randomly assigned to receive either 10 home visits focused on decluttering or be placed on a waitlist. The study will assess the impact of this augmented intervention on hoarding symptoms, clutter levels, and daily functioning. Additionally, the trial will explore the cost-effectiveness of the combined approach.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older diagnosed with hoarding disorder who live within a one-hour commute from the social services office in Stockholm, Sweden.

Not a fit: Patients currently receiving CBT for hoarding disorder or those with severe home conditions that pose risks to staff may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could significantly reduce hoarding symptoms and improve daily functioning for individuals with hoarding disorder.

How similar studies have performed: Previous research has indicated that in-home decluttering can be a promising intervention when combined with CBT, but this specific approach has not yet been tested in a randomized controlled trial.
