This systematic review and meta-analysis investigated the efficacy of spelling interventions for the remediation of dyslexia and spelling deficits. Theoretically important moderators, such as the treatment approach as well as orthographic and sample characteristics, were also considered. Thirty-four controlled trials that evaluated spelling interventions in children, adolescents, and adults with dyslexia and spelling deficits were included. Results show that treatment approaches using phonics, orthographic (graphotactic or orthographic phonological spelling rules), and morphological instruction had a moderate to high impact on spelling performance. A significant influence of interventions that teach memorization strategies to improve spelling could not be confirmed. This work shows that understanding the principles of an orthography is beneficial for learners with dyslexia or spelling deficits and presents key components for effective spelling intervention.

这项系统的审查和荟萃分析调查了拼写干预对诵读困难和拼写缺陷的治疗效果。从理论上讲，重要的主持人，例如治疗方法以及正字法和样本特征也要考虑。包括34项对照试验，评估了患有阅读障碍和拼写缺陷的儿童，青少年和成人的拼写干预措施。结果表明，使用拼音，正字法（笔法或拼字法语音拼写规则）和形态学指导的处理方法对拼写性能有中等到较高的影响。教书记忆策略以改善拼写的干预措施的重大影响无法确定。
