"Compulsive Shopping" is characterized by poorly controlled preoccupations/urges/behaviors focused on shopping and spending, causing significant distress/impairment. This study looked at what roles executive and related memory problems might exist in compulsive shopping. 205 adults completed on-line questionnaires measuring compulsive shopping, mood, as well as working memory and inhibition components of executive function. The was used to assign participants to either a (HCS) group or (LCS) group. Working memory (WM) and inhibition control (IC) were measured as two components of executive function (EF) using the (ADEXI), the DEX-R) measured general EF. The measured anxiety and depression. MANCOVA and mediation analyses were carried out controlling for age, gender, anxiety, depression. The HCS group scored significantly higher on all three EF measures, indicating greater executive difficulties. Subsequent mediation analyses with the ADEXI-IC as the mediator removed the significance of the relationship between Group and both the DEX-R and ADEXI-WM outcome variables. Thus, observed Group difference in DEX-R and ADEXI-WM could be fully accounted for by group differences in inhibitory control. The results highlight the role inhibitory control plays in compulsive shopping.
“强迫性购物”的特点是对购物和消费的难以控制的强烈关注/冲动/行为，导致明显的痛苦/障碍。本研究着眼于执行功能和相关记忆问题在强迫性购物中可能扮演的角色。205 名成年人完成了在线问卷，测量强迫性购物、情绪，以及工作记忆和抑制执行功能的成分。使用来将参与者分配到高强迫性购物（HCS）组或低强迫性购物（LCS）组。使用（ADEXI）测量工作记忆（WM）和抑制控制（IC）作为执行功能（EF）的两个组成部分，（DEX-R）测量一般 EF。用测量焦虑和抑郁。在控制年龄、性别、焦虑和抑郁的情况下，进行 MANCOVA 和中介分析。HCS 组在所有三个 EF 测量上的得分明显更高，表明执行困难更大。随后的中介分析显示，ADEXI-IC 作为中介物，消除了组间差异与 DEX-R 和 ADEXI-WM 结果变量之间关系的显著性。因此，DEX-R 和 ADEXI-WM 中观察到的组间差异可以完全归因于抑制控制的组间差异。结果强调了抑制控制在强迫性购物中的作用。
