In the era of Corona and due to social distancing, the amount of social participation decreased drastically. The purpose of this research was to investigate the relationship between life expectancy and social participation during the Corona epidemic. This research was of correlational type and the statistical population of the current research consisted of students of Farzangan ۴ Karaj High School (۲۰۲۰-۲۰۲۱). The study consisted of ۱۷۵ students who were selected by stratified random sampling based on Morgan's table. The measurement tools in the present study were two questionnaires: "Schneider's Life Expectancy Questionnaire" and "Sohrabi et al.'s Social Participation Questionnaire". Pearson's correlation coefficient and regression analysis were used to analyze the research hypotheses. The results of the research showed that all the correlation coefficients calculated between life expectancy and its components, including factor thinking and strategic thinking with social participation, were positive and significant at the alpha level of ۰.۰۱ (p < ۰.۰۱). The positive coefficients obtained show that there is a direct relationship between life expectancy and social participation, and students who have higher life expectancy have higher social participation. Also, according to the results, life expectancy explains ۲۳.۳% of social participation, and its subscales, i.e., factor thinking, ۲۰.۶% and strategic thinking, predict ۱۴.۲% with social participation. As a result, life expectancy has a positive and significant relationship with social participation with the two subscales of agentive thinking and strategic thinking.
