A Meta-Analysis on the Effects of Aromatherapy: Overall Effect Size, Effect Size on the Moderating Variables, Effect Size on the Dependent Variables

The main purpose of this study was to analyze synthetically researches and draw up guidelines direction on aromatherapy. To analyze the data, we selected 29 previous studies which is related with the aromatherapy. Effect sizes on the moderating variables, dependent variables and the whole of aromatherapy were calculated by using the CMA (Comprehensive Meta-Analysis) program. This study implemented meta analysis by using the random-effects model as the results of homogeneity test had statistically significant effect. We found that the overall effect size of 121 from selected studies had upper-middling effects at the level of .678. The effect size of general groups as a study participants had an effect than patient groups at the level of .751. The effect size of dry inhalation as a method inhaling aroma had an effect than diffusion inhalation at the level of .684. And also the effect sizes of period experiments (21-30day), number of time (11-15 time), time once per experiment (2minutes), dependant variables(psychology response) yield effects .905, 1.095, 1.332 and .768 respectively. As the result, this study implies a way which is to derive effectively further studies on the aroma therapy.
