Price, JosephA. Dake, Judy Murnan, Jaime Dimmig, and SutoidemAkpanudo  \nABSTRACT  \nThis article has three purposes: to explain the two different uses of power analysis that can be used in health education research; to examine the extent to which power analysis is being used in published health education research; and to explain the implications of not using power analysis in research studies. Articles in seven leading health education journals (American Journal of Health Behavior, American Journal of Health Education, American Journal of Health Promotion, Health Education &Behavior, Health Education Research, Journal of American College Health, and Journal of School Health) were analyzed for the years 2000–2003. For four of the seven journals, less than 5% of their research articles reported a power analysis. Only two journals (American Journal of Health Behavior and Health Education Research) had a modest number of research articles (14–35%) that reported power analysis. This is the first reported examination of power analysis in health education journals. The findings indicate a potential problem with the quality of health education research being reported.  \nINTRODUCTION  \nThere are several purposes to this article, the first of which is an overview of power analysis: what it is, why it is important, and how to calculate it. The second purpose is the relative importance of power analysis to adequate survey return rates. While these two issues could be learned elsewhere (e.g., various research methods texts and journal articles), this article provides those readers who are less familiar with power analysis a summary of the key points as they relate to health education survey research. The third purpose of this article is to assess the use of power analysis in seven leading health education journals. This article is directed at readers unfamiliar with power analysis, as well as those who are better versed in its use, with the intent being to increase the appropriate use of power analysis in health education survey research.  \nTheory of Power Analysis  \nAnytime a researcher conducts a quantitative study, it is essential that the researcher calculate the statistical power of a study before any data are collected, with the possible exception of pilot studies. In fact, grant proposals to some federal agencies require that a power analysis be conducted before the proposal is submitted. A statistical power assessment tells us how likely it is that a statistical significance test (e.g., t-test, ANOVA, chi-square) will detect a significant difference between two or more groups, given that a difference actually exists. In other words, statistical tests attempt to disprove the null hypothesis that there is no difference or no association between or among various samples.1 Rejection of a null hypothesis means that a difference or an association may be inferred from the study sample to the population.  \nUsing statistical significance tests to assess data from a study can result in several different outcomes (Figure 1) . In the first cell (A), we see that the null hypothesis is  \nJames H.
