摘要

分层线性建模(HLM)已被推荐为一种元分析技术,用于单例实验设计(SCED)研究的定量综合。HLM方法是灵活的,可以对各种不同的SCED数据复杂性进行建模,例如干预异质性。使用HLM的一个主要优点是,参与者和/或研究特征可以被纳入模型中,试图解释干预的异质性。在SCED研究的荟萃分析中纳入调节因子尚未受到关注,需要进行方法学研究。在扩展方法学工作以验证包括不同级别的调节者在内的分层线性模型之前,需要对该领域中通常遇到的调节者的特征进行概述。这将为未来方法研究中嵌入的设计条件提供信息,并确保这些条件是现实的,对SCED荟萃分析领域具有代表性。本研究介绍了SCED荟萃分析的系统综述结果,特别关注调节因子特征。最初的搜索共产生910篇文章和书籍章节。在排除重复研究和非同行评审研究后,两名独立研究人员保留并筛选了658项独特的同行评审研究。60篇文章符合纳入标准,符合数据检索条件。介绍了从这60项荟萃分析中检索到的慢化剂特征的分析结果。结果部分的第一部分概述了每个主持人级别(在参与者级别、参与者级别和研究级别内)的主持人特征,包括主持人类型、主持人数量与该级别单元数量的比率、测量量表和数据缺失程度。结果部分的第二部分侧重于用于量化主持人有效性的指标和分析方法。根据系统审查的结果,对未来方法学工作中应纳入的条件提出了建议。

Characteristics of Moderators in Meta-Analyses of Single-Case Experimental Design Studies.

Hierarchical linear modeling (HLM) has been recommended as a meta-analytic technique for the quantitative synthesis of single-case experimental design (SCED) studies. The HLM approach is flexible and can model a variety of different SCED data complexities, such as intervention heterogeneity. A major advantage of using HLM is that participant and-or study characteristics can be incorporated in the model in an attempt to explain intervention heterogeneity. The inclusion of moderators in the context of meta-analysis of SCED studies did not yet receive attention and is in need of methodological research. Prior to extending methodological work validating the hierarchical linear model including moderators at the different levels, an overview of characteristics of moderators typically encountered in the field is needed. This will inform design conditions to be embedded in future methodological studies and ensure that these conditions are realistic and representative for the field of SCED meta-analyses. This study presents the results of systematic review of SCED meta-analyses, with the particular focus on moderator characteristic. The initial search yielded a total of 910 articles and book chapters. After excluding duplicate studies and non peer-reviewed studies, 658 unique peer-reviewed studies were maintained and screened by two independent researchers. Sixty articles met the inclusion criteria and were eligible for data retrieval. The results of the analysis of moderator characteristics retrieved from these 60 meta-analyses are presented. The first part of the results section contains an overview of moderator characteristics per moderator level (within-participant level, participant level, and study level), including the types of moderators, the ratio of the number of moderators relative to the number of units at that level, the measurement scale, and the degree of missing data. The second part of the results section focuses on the metric used to quantify moderator effectiveness and the analysis approach. Based on the results of the systematic review, recommendations are given for conditions to be included in future methodological work.

期刊介绍: For two decades, researchers and practitioners have turned to Behavior Modification for current scholarship on applied behavior modification. Starting in 1995, in addition to keeping you informed on assessment and modification techniques relevant to psychiatric, clinical, education, and rehabilitation settings, Behavior Modification revised and expanded its focus to include treatment manuals and program descriptions. With these features you can follow the process of clinical research and see how it can be applied to your own work. And, with Behavior Modification, successful clinical and administrative experts have an outlet for sharing their solutions in the field.
