This meta-analysis assessed the efficacy of the Cogmed Working Memory Training program in improving near-transfer measures (verbal and visuospatial working memory) and far-transfer measures (attention, executive function, and academic achievement) in school-age children with and without neurological insults or disorders. Relevant studies were searched in databases and clinical trial registries using the keyword Cogmed. Ten published studies and unpublished data from one study met the inclusion criteria. Hedges was calculated for each outcome measure obtained at pre-intervention, post-intervention, and 3-6 month time points. Analysis compared outcome measures in the control versus experimental groups and examined the role of moderators on treatment effects (control group intervention, intervention environment). Data revealed significant medium-size effects of the Cogmed program in improving verbal and visuospatial working memory post-intervention and for verbal working memory only at the 3-6 month time point. However, the training did not generalize to the far-transfer measures. Analyses indicated that only the type of intervention provided for the control group moderated treatment effects on verbal and visual working memory. Meta-analytic findings suggest that the Cogmed program leads to short-term improvements and in some cases, long-term improvements in working memory in school-age children; however, these effects may not generalize to far-transfer measures.
本荟萃分析评估了 Cogmed 工作记忆训练计划在改善学龄儿童近迁移测量（言语和视空间工作记忆）和远迁移测量（注意力、执行功能和学业成绩）方面的疗效，这些儿童包括有或无神经损伤或障碍者。使用关键字“Cogmed”在数据库和临床试验登记处搜索相关研究。符合纳入标准的有 10 项已发表的研究和 1 项研究的未发表数据。在干预前、干预后和 3-6 个月的时间点，计算每个结果测量的 Hedges 值。分析比较了对照组和实验组的结果测量，并研究了调节因素对治疗效果的影响（对照组干预、干预环境）。数据显示，Cogmed 计划在干预后显著改善了言语和视空间工作记忆，并且仅在 3-6 个月的时间点显著改善了言语工作记忆，具有中等效果。然而，训练并未推广到远迁移测量。分析表明，只有对照组提供的干预类型调节了言语和视觉工作记忆的治疗效果。荟萃分析结果表明，Cogmed 计划可导致学龄儿童短期和在某些情况下长期改善工作记忆；然而，这些效果可能不会推广到远迁移测量。
