Background <p>Procrastination, defined as the voluntary delay of intended actions, affects personal and academic tasks and is linked to decreased quality of life and well-being. This study evaluates the prevalence, causes, and effects of chronic procrastination among adults in Saudi Arabia, with a focus on demographic associations, psychological impacts, and coping strategies.</p> Objective <p>To determine the prevalence of chronic procrastination among adults in Saudi Arabia, identify its demographic and psychological predictors, and evaluate its effects on personal well-being, academic performance, and daily functioning.</p> Methods <p>A cross-sectional study was conducted among 1,093 participants, aged 18–55 years, residing in Saudi Arabia. Data were collected through a self-administered online survey covering demographics, procrastination behaviors, and coping strategies. Statistical analysis, including chi-square and exact probability tests, identified associations between procrastination frequency and demographic factors.</p> Results <p>Of the participants, approximately 70% reported frequent procrastination, with academic tasks (56.6%) and household chores (13.9%) being the most delayed activities. Common reasons for procrastination included poor time management (76.2%), boredom (59.7%), and lack of motivation (57.3%). Over 65% experienced health impacts, such as sleep problems and stress. Procrastination significantly affected both personal life (55.1%) and work/studies (70%). Time management, task division, and deadline-setting were the most utilized strategies, though effectiveness varied.</p> Conclusion <p>The study indicates a high prevalence of procrastination among young adults, particularly students, with detrimental impacts on personal and academic functioning. Training programs focused on time management and prioritization could help reduce procrastination.</p> Categories <p>Psychology, Behavioral science, Time management, Well-being.</p>
