Insights
This study characterized hoarding behavior in clinical patients, finding that Hoarding Disorder (HD) was diagnosed in less than half. Alcohol use disorder was noted in patients without HD, suggesting home visitation programs aid early detection.
Area of Science:
- Clinical Psychology
- Psychiatry
- Public Health
Background:
- Hoarding behavior is prevalent but poorly understood in clinical settings.
- Hoarding Disorder (HD) is a key component, but not all individuals with hoarding behavior have HD.
- Differentiating between hoarding behavior and HD is crucial for effective treatment.
Purpose of the Study:
- To characterize a clinical sample of patients with hoarding behavior.
- To identify differential characteristics between patients with and without a formal HD diagnosis.
- To evaluate the role of home visitation programs in managing hoarding behavior.
Main Methods:
- Analysis of patients from a Barcelona home visitation program (2013-2020).
- Inclusion criteria: score ≥ 4 on the Clutter Image Rating scale.
- Assessment of sociodemographic data, DSM-5 diagnoses, and clinical information.
Main Results:
- 243 subjects were included; hoarding behavior was often long-standing (median 10 years).
- 100% of cases presented hoarding-related complications.
- Hoarding Disorder (HD) was diagnosed in 117 patients (48.1%).
Conclusions:
- Differential characteristics exist between patients with and without HD.
- Alcohol use disorder may be significant in patients without HD.
- Home visitation programs can facilitate early detection and prevent complications.
Objective:
Hoarding behaviour is a common but poorly characterised problem in real-world clinical practice. Although hoarding behaviour is the key component of Hoarding Disorder (HD), there are people who exhibit hoarding behaviour but do not suffer from HD. The aim of the present study was to characterise a clinical sample of patients with clinically relevant hoarding behaviour and evaluate the differential characteristics between patients with and without HD.
Methods:
This study included patients who received treatment at the home visitation program in Barcelona (Spain) from January 2013 through December 2020, and scored ≥ 4 on the Clutter Image Rating scale. Sociodemographic, DSM-5 diagnosis, clinical data and differences between patients with and without an HD diagnosis were assessed.
Results:
A total of 243 subjects were included. Hoarding behaviour had been unnoticed in its early stages and the median length in the sample was 10 years (IQR 15). 100% of the cases had hoarding-related complications. HD was the most common diagnosis in 117 patients (48.1%).
Conclusions:
The study found several differential characteristics between patients with and without HD diagnosis. Alcohol use disorder could play an important role among those without HD diagnosis. Home visitation programs could improve earlier detection, preventing hoarding-related complications.
