尽管记忆表现是强迫症（OCD）的一个普遍研究方面，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，本荟萃分析检验了Harkin和Kessler （2011b）的执行功能、绑定复杂性和记忆负荷（EBL）分类系统对强迫症患者受影响和未受影响的记忆表现的预测有效性。我们采用了多层次元分析方法（Viechtbauer, 2010）来适应EBL模型的相互依赖性和效应量的相互依赖性（来自144项研究的305个效应量，包括4,424名强迫症患者）。结果表明，EBL模型可以预测记忆性能；也就是说，随着EBL需求的增加，强迫症患者在记忆任务中的表现越来越差。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、记忆负荷和视觉或口头任务差异。子任务效应量的比较也与EBL分类的认知参数基本一致。我们的结论是，标准化的任务编码和多层次的荟萃分析为研究强迫症和其他疾病的记忆和认知表现的多维模型提供了一种新的方法。
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.
