Abstract

Hoarding is the excessive acquisition of, and failure to discard of, large numbers of items, leading to personal distress. Impairments on memory and executive functions have been systematically associated with hoarding behavior, predominantly focusing upon clinical (mainly middle-aged-elderly) patients with hoarding and/or PTSD. We were interested in hoarding-related memory and executive problems in younger non-clinical hoarders or non-hoarders, based on their Saving Inventory-Revised scores. In total, 113 young adults (aged 18–35 years) were assigned to either a hoarder group (N = 40) or non-hoarder group (N = 73) determined by their scores on the Saving Inventory-Revised (SI-R). Working memory (WM) and inhibition control (IC) were measured using the Adult Executive Functioning Inventory (ADEXI) and the Dysexecutive Questionnaire Revised (DEX-R) measured general executive function (EF). The Hospital Anxiety and Depression Scale measured anxiety and depression. After controlling for gender and anxiety, the analysis revealed that the hoarders reported significantly more problems than the non-hoarders on both the IC and general EF. There was no significant between-group difference on the WM sub-scale ADEXI. Self-reported deficits in IC and EF are associated with hoarding behavior. The IC deficits cold explain hoarders’ inability to resist urges to buy, and general EF deficits suggest other domains are involved.

摘要

囤积是指过度获取大量物品，但未能丢弃，导致个人痛苦。记忆和执行功能的损害与囤积行为系统地相关，主要集中在具有囤积和/或 PTSD 的临床（主要是中年老年人）患者身上。我们对年轻的非临床囤积者或非囤积者的囤积相关记忆和执行问题感兴趣，基于他们的储蓄库存修正分数。总共有 113 名年轻人（18-35 岁）被分配到囤积者组（N  = 40）或非囤积者组（N  = 73），这取决于他们在储蓄清单修订版上的得分（先生）。工作记忆 (WM) 和抑制控制 (IC) 使用成人执行功能量表(ADEXI) 和功能障碍问卷修订版 ( DEX-R) 测量一般执行功能 (EF) 进行测量。医院焦虑和抑郁量表测量焦虑和抑郁。在控制了性别和焦虑之后，分析显示，在 IC 和一般 EF 上，囤积者报告的问题明显多于非囤积者。WM 子量表 ADEXI 没有显着的组间差异。自我报告的 IC 和 EF 缺陷与囤积行为有关。IC 缺陷冷淡地解释了囤积者无法抵制购买的冲动，而一般的 EF 缺陷表明涉及其他领域。
