The purpose of this study is to analyze research trends related to suicidal ideation among the elderly. To this end, 82 academic papers were selected through the Research Information Sharing Service (RISS) using keywords such as "elderly," "suicidal ideation," and "depression." These studies were systematically categorized based on general characteristics, research variables, keywords, statistical analyses, and research methods. The first relevant study was published in 2006, and since then, two to three papers have been published annually. Notably, from 2013 to 2020, the average number of publications increased to eight per year. However, since 2021, the number of studies has returned to two to three per year, indicating that the earlier upward trend has not been sustained. In terms of sample size, studies with 301 to 400 participants were the most common, accounting for 48 papers. Quantitative research made up 96% of all studies. The most frequently used statistical methods were regression analysis, correlation analysis, and t-tests. Keywords such as "suicidal ideation," "depression," and "stress"—all with negative connotations—were predominantly used, while positive terms such as "self-esteem," "social support," and "life satisfaction" were relatively underrepresented. Therefore, in light of the transition into a super-aged society, it is recommended that future research increase in volume and focus more on qualitative approaches that explore life satisfaction, reduction of depression, and the value of life among the elderly. Moreover, greater emphasis should be placed on studies related to policy, institutional, and social measures for suicide prevention among older adults.
