Insights
Hoarding is a complex behavior involving excessive acquisition and difficulty discarding items, often linked to obsessive-compulsive disorders (OCDs). Further research is needed to refine its definition and guide effective therapeutic interventions.
Area of Science:
- Psychiatry
- Behavioral Science
- Clinical Psychology
Background:
- Hoarding is a behavioral abnormality characterized by excessive collection of poorly usable objects.
- It is often associated with obsessive-compulsive disorders (OCDs) and geriatric populations.
- The existing literature on hoarding is heterogeneous, lacking a consistent definition.
Purpose of the Study:
- To describe the psychopathological and clinical spectrum of hoarding.
- To contribute to a clearer classification of hoarding disorder.
- To review the existing literature on hoarding behavior.
Main Methods:
- Systematic review of the literature on hoarding.
- Discussion of psychopathological and clinical aspects of hoarding.
- Analysis of the heterogeneity in hoarding research.
Main Results:
- Hoarding is a complex behavioral phenomenon linked to various mental disorders.
- Its psychopathological structure can include elements of OCDs, impulse-control disorders, and ritualistic behavior.
- Severe self-neglect is a potential consequence of hoarding.
Conclusions:
- The term 'hoarding' has limited heuristic value without further specification.
- Current understanding of hoarding does not adequately guide therapeutic interventions.
- Hoarding requires careful case-by-case evaluation in relation to psychopathological concepts.
Objective:
Hoarding is a behavioural abnormity characterized by the excessive collection of poorly usable objects. It is described mainly in association with obsessive-compulsive disorders (OCDs) and in geriatric populations. Yet the literature on the phenomenon is heterogeneous and the notion obviously lacks a consistent definition. This review attempts to describe the psychopathological and clinical spectrum of hoarding and may contribute to clarify its classification.
Method:
Systematic review and discussion of the literature on hoarding.
Results:
Hoarding is a complex behavioural phenomenon associated with different mental disorders. The psychopathological structure is variously composed of elements of OCDs, impulse-control disorders, and ritualistic behaviour. Severe self-neglect is a possible consequence of hoarding.
Conclusion:
Without further specifications the term hoarding is of limited heuristic value and cannot guide therapeutic interventions satisfactorily. The condition needs to be evaluated carefully in every particular case in relation to the aforementioned psychopathological concepts.
