Even though memory performance is a commonly researched aspect of obsessive-compulsive disorder (OCD), a coherent and unified explanation of the role of specific cognitive factors has remained elusive. To address this, the present meta-analysis examined the predictive validity of Harkin and Kessler's (2011b) executive function, binding complexity, and memory load (EBL) Classification System concerning affected versus unaffected memory performance in OCD. We employed a multilevel meta-analytic approach (Viechtbauer, 2010) to accommodate the interdependent nature of the EBL model and interdependency of effect sizes (305 effect sizes from 144 studies, including 4,424 OCD patients). Results revealed that the EBL model predicted memory performance; that is, as EBL demand increases, those with OCD performed progressively worse on memory tasks. Executive function was the driving mechanism behind the EBL's impact on OCD memory performance, as it negated binding complexity, memory load, and visual or verbal task differences. Comparisons of subtask effect sizes were also generally in accord with the cognitive parameters of the EBL taxonomy. We conclude that standardized coding of tasks along individual cognitive dimensions and multilevel meta-analyses provides a new approach to examine multidimensional models of memory and cognitive performance in OCD and other disorders.

强迫症记忆表现的多维模型建模：多层次元分析评论。

尽管记忆力是强迫症 (OCD) 的一个普遍研究的方面，但对特定认知因素的作用的连贯和统一的解释仍然难以捉摸。为了解决这个问题，本荟萃分析检查了 Harkin 和 Kessler (2011b) 执行功能、结合复杂性和记忆负荷 (EBL) 分类系统关于强迫症中受影响与未受影响的记忆性能的预测有效性。我们采用多级元分析方法 (Viechtbauer, 2010) 来适应 EBL 模型的相互依赖性质和效果大小的相互依赖性（来自 144 项研究的 305 个效果大小，包括 4,424 名强迫症患者）。结果显示，EBL 模型预测了记忆性能；也就是说，随着 EBL 需求的增加，强迫症患者在记忆任务上的表现越来越差。执行功能是 EBL 对强迫症记忆性能影响背后的驱动机制，因为它否定了绑定复杂性、记忆负荷以及视觉或语言任务差异。子任务效果大小的比较也大体上符合 EBL 分类法的认知参数。我们得出结论，沿着个体认知维度和多层次元分析的标准化任务编码提供了一种新方法来检查强迫症和其他疾病中记忆和认知表现的多维模型。（PsycInfo 数据库记录 (c) 2021 APA，保留所有权利）。子任务效果大小的比较也大体上符合 EBL 分类法的认知参数。我们得出结论，沿着个体认知维度和多层次元分析的标准化任务编码提供了一种新方法来检查强迫症和其他疾病中记忆和认知表现的多维模型。（PsycInfo 数据库记录 (c) 2021 APA，保留所有权利）。子任务效果大小的比较也大体上符合 EBL 分类法的认知参数。我们得出结论，沿着个体认知维度和多层次元分析的标准化任务编码提供了一种新方法来检查强迫症和其他疾病中记忆和认知表现的多维模型。（PsycInfo 数据库记录 (c) 2021 APA，保留所有权利）。
