Research Trends on Self-Determined Solitude Motivation among Koreans

Objectives The purpose of this study is to analyze research trends on self-determined solitude motivation among Koreans. Through this analysis, the study aims to review existing research and broaden the understanding of self-determined solitude motivation, thereby suggesting directions for future research. Methods A total of 35 journal articles and master's and doctoral theses published in Korean and English from 2012 to 2023 were analyzed. We examined overall publication trends, such as publication year and academic field, as well as research method trends, including research types, subjects, and statistical methods. To investigate the content trends of variables studied in relation to self-determined solitude motivation, we categorized the variables by area and analyzed their frequency and co-occurrence. Results First, approximately 80% of the studies on self-determined solitude motivation among Koreans were published after 2019, with a slightly higher proportion of theses. Most of the research was conducted in the fields of psychology and education. Second, quantitative research was predominant, with young adults being the primary subjects. The measurement tool developed by Lim et al. (2012) was mainly used, and regression analysis and cluster analysis were commonly employed. Third, the majority of variables studied in relation to self-determined solitude motivation among Koreans were personal variables, with a focus on emotional and personality-related variables. Frequently studied variables in conjunction with self-determined solitude motivation included life satisfaction and well-being, loneliness, eating alone, depression, and adult attachment. Conclusions Research on self-determined solitude motivation among Koreans has been increasing since 2019, with a significant focus on master's theses and quantitative studies targeting young adults. Many studies have examined the relationship between self-determined solitude motivation and factors such as life satisfaction and well-being, loneliness, and eating alone. This suggests the need for future research employing diverse methods and perspectives.
