The knowledge gained from studying diverse populations should help to address inequities and prepare us to deal with the needs of the increasing number of older minorities in this country. At the same time, research that is not properly conducted threatens to lead us astray and misconstrue relationships and outcomes related to behavioral aspects of aging. In this article, we propose that simple comparisons between groups are neither necessary nor sufficient to advance our understanding of ethnic minorities. We discuss common pitfalls conducted in group-differences research, including a specific treatment on the issue of statistical power issues. Our goal is to encourage the use of multiple methodological designs in the study of issues related to racial and ethnic minorities by demonstrating some of the advantages of lesser employed approaches.
通过研究不同人群所获得的知识，应有助于解决不平等问题，并使我们有能力应对我国日益增多的老年少数族裔的需求。与此同时，开展不当的研究可能会使我们误入歧途，误解与衰老行为方面相关的关系和结果。在本文中，我们提出，群体间的简单比较对于增进我们对少数族裔的理解既无必要也不充分。我们讨论了群体差异研究中常见的陷阱，包括对统计功效问题的具体处理。我们的目标是通过展示一些较少使用的方法的优势，鼓励在研究与种族和少数族裔相关的问题时采用多种方法设计。
