The purpose of this study is to determine the relationship levels between university students' life satisfaction, academic procrastination behavior, and student's individual responsibility behaviors. The research is conducted as a correlational study within a survey model. The study was conducted with 401 students, 256 female and 145 male, enrolled in a 4-year undergraduate program at Akdeniz University during the academic year 2022-2023. The data for the research were collected through face-to-face interviews using a personal information form, the 'Life Satisfaction Scale' adapted into Turkish by Dagli and Baysal (2016) from the original developed by Diener, Emmons, Larsen, Griffin (1985), the 'Academic Procrastination Scale' adapted into Turkish by Balkis (2006) from the original developed by Aitken (1982), and the 'Student's Individual Responsibility Scale' adapted into Turkish by Dogan (2015) from the original developed by Signn and Ader (2001). According to the findings of the research, there is a negative relationship between university students' life satisfaction and academic procrastination levels, a positive relationship between life satisfaction and student's individual responsibility behaviors, and a negative relationship between academic procrastination and student's individual responsibility behaviors.
