BACKGROUND
Current cognitive behavioral models of hoarding view hoarding as a multifaceted problem stemming from various information processing deficits. However, there is also reason to suspect that the consequences of hoarding may in turn impact or modulate deficits in information processing. The current study sought to expand upon the existing literature by manipulating clutter to examine whether the presence of a cluttered environment affects information processing.
METHODS
Participants included 34 individuals with hoarding disorder. Participants were randomized into a clutter or non-clutter condition and asked to complete various neuropsychological tasks of memory and attention.
RESULTS
Results revealed that hoarding severity was associated with difficulties in sustained attention. However, individuals in the clutter condition relative to the non-clutter condition did not experience greater deficits in information processing.
LIMITATIONS
Limitations include the cross-sectional design and small sample size.
CONCLUSIONS
The current findings add considerably to a growing body of literature on the relationships between information processing deficits and hoarding behaviors. Research of this type is integral to understanding the etiology and maintenance of hoarding.
背景
当前囤积症的认知行为模型将囤积视为一个源于各种信息处理缺陷的多方面问题。然而，也有理由怀疑囤积的后果可能反过来影响或调节信息处理方面的缺陷。本研究试图通过操纵杂乱程度来扩展现有文献，以检验杂乱环境的存在是否会影响信息处理。
方法
参与者包括34名患有囤积症的个体。参与者被随机分为杂乱组或非杂乱组，并被要求完成各种记忆和注意力方面的神经心理学任务。
结果
结果显示囤积严重程度与持续注意力困难有关。然而，与非杂乱组相比，处于杂乱环境中的个体在信息处理方面并未出现更大的缺陷。
局限性
局限性包括横断面设计和样本量小。
结论
当前的研究结果极大地丰富了关于信息处理缺陷与囤积行为之间关系的文献。这类研究对于理解囤积症的病因和维持机制至关重要。
