Abstract

Low statistical power undermines a credible scientific discipline. This paper presents a statistical power assessment of experimental communication research based on a random sample of 416 studies published in five central communication journals over the last two decades (2001–2023). Our analyses showed that there was a lack of attention to power and power analysis, with the majority of studies not even mentioning statistical power. We also demonstrated that between-subjects studies were overall underpowered for two-group, one-way multi-group, and factorial designs. Our findings suggest that conducting power analyses to ensure adequate statistical power should be a key priority for experimental communication research.

走向更强大的实验传播学：二十年研究评估（2001-2023）

统计能力低会破坏可信的科学学科。本文基于在过去二十年（2001-2023年）中发表在五家中央传播期刊上的416项研究的随机样本，对实验传播研究进行了统计能力评估。我们的分析表明，缺乏对权力和权力分析的关注，大多数研究甚至没有提到统计权力。我们还证明，两组、单向多组和析因设计的受试者间研究总体上效果不足。我们的研究结果表明，进行功率分析以确保足够的统计功率应该是实验传播研究的关键优先事项。

期刊介绍： Empirical research in communication began in the 20th century, and there are more researchers pursuing answers to communication questions today than at any other time. The editorial goal of Communication Research is to offer a special opportunity for reflection and change in the new millennium. To qualify for publication, research should, first, be explicitly tied to some form of communication; second, be theoretically driven with results that inform theory; third, use the most rigorous empirical methods; and fourth, be directly linked to the most important problems and issues facing humankind. Critieria do not privilege any particular context; indeed, we believe that the key problems facing humankind occur in close relationships, groups, organiations, and cultures.
