Throughout the educational, medical, psychological, and social sciences, meta-analysis is the present-day, broadly accepted means for combining many quasi-experiments in a synthesis for the purpose of establishing the weight of scientific evidence bearing on a certain research question. Meta-analysis thereby is the preferred method for determining the preponderance of evidence in clinical-outcome research relating to questions of treatment efficacy and treatment effectiveness. Relatively few meta-analyses appear in the literature of the communication disorder sciences. The purpose of this tutorial is to enhance the familiarity and accessibility of this technology in the domains of audiology and speech-language pathology. The results of the accompanying example constitute a preliminary meta-analysis of patient-perceived treatment effectiveness. The substance of the tutorial, however, transcends disciplinary interests regarding types of communication disorder.
在教育、医学、心理学和社会科学领域，元分析是当今广泛接受的一种方法，用于将多个准实验综合起来，以确定与某个研究问题相关的科学证据的权重。因此，元分析是确定临床结果研究中有关治疗效果和治疗有效性问题的证据优势的首选方法。在交流障碍科学文献中出现的元分析相对较少。本教程的目的是提高听力学和言语语言病理学领域对这项技术的熟悉程度和可及性。随附示例的结果构成了对患者感知的治疗效果的初步元分析。然而，本教程的内容超越了对交流障碍类型的学科兴趣。
