<p dir="ltr">Procrastination is highly prevalent among college students and has profound impacts on college students’ academic performance, career development, mental health, and overall well-being. In recent years, researchers have begun exploring mindfulness as a potential protective factor and intervention for procrastination. This dissertation is composed of two independent studies that review and expand findings on the relationship between mindfulness and procrastination in college students. Chapter 1 is a systematized literature review of 21 studies on mindfulness and procrastination, revealing a consistent negative relationship between the two constructs across diverse cultural contexts. While some studies identified mediators and moderators of the relationship, most treated this relationship as a direct effect. In addition, majority of the studies used cross-sectional design and self-report quantitative measures. Chapter 2 tested a mediation model that explainsrelationships among mindfulness, self-compassion, and procrastination among 236 undergraduate students using self-report questionnaires. Results revealed that mindfulness significantly predicted lower procrastination, both directly and indirectly through self-compassion. Self-compassion partially mediated the negative relationship between mindfulness and procrastination. These findings indicate that mindfulness may reduce procrastination by promoting self-compassion, which demonstrates the potential of mindfulness interventions in reducing procrastination of college students. Limitations and future directions are discussed at the end of each chapter.</p>
