Das kognitiv-behaviorale Modell des pathologischen Hortens: Evidenz und Behandlungsansätze
摘要
Hoarding disorder is now classified as a distinct disorder in established classification systems. One reason for this classification is the consistent finding of poorer treatment outcomes with therapy manuals that are currently available. This raises the question of the relevance of disorder-specific causal and maintaining factors, as well as treatment approaches. The aim of this article is to describe the evidence for the cognitive–behavioral model and the related treatment. Regarding information processing deficits, individuals with hoarding disorder consistently exhibit impairments in categorization skills and reduced cognitive confidence. Dysfunctional beliefs and excessive emotional attachment to possessions have shown a significant association with hoarding symptoms in previous studies. Avoidance behavior appears to be relevant to the disorder but not disorder-specific. One treatment manual addresses these factors by teaching cognitive strategies (such as organizational training), cognitive techniques, and exposure therapy (through discarding objects). Initial findings suggest effectiveness for some patients. Optimizing treatment and intensification of research activities would be desirable for this disorder. With prevalence rates of almost 5%, the use of disorder-specific diagnostics and therapy in clinical practice may be indicated.
