The aim of this study is to explore the types of academic approaches that utilize the enneagramto study parents, and to emphasize the enneagram's importance. We analyzed the research subjectsof 432 thesis and journal articles published in Korea that contained the enneagram as the key topicfrom 1999 to 2013. We divided academic approaches into seven areas: literature research, contentsanalysis, survey, experimental research, in-depth interview, program development, and scaledevelopment. Then we sorted the articles by subject to single out studies that analyze parents toelucidate their academic development.The results show that since 2009 the dominant trend in researches utilizing the enneagram tostudy parents is to conduct in experimental research, and it is continuously on the rise. Oursuggestion is as follows: we admit that the number of subjects of analysis may have beenaccidently omitted by the provider. Secondly, sorting out the process that classified mixed researchmethods as miscellaneous may need reclassification in the future. Thirdly, comparing the researchtrend path with other countries may be of value to enlighten enneagram researchers with futuresubjects of research.
