| Abstract: | Adolescence is a critical developmental period characterized by rapid cognitive, emotional, and social transformation. During this stage, establishing psychological well-being and adaptive thought patterns can influence lifelong happiness. Positive psychology, emphasizing strengths and virtues, identifies two particularly effective approaches positive thinking and gratitude practices. This paper explores the theoretical underpinnings, empirical evidence, mechanisms of change, and practical implications of implementing these interventions among adolescents. Drawing from cognitive-behavioral and broaden-and-build frameworks, the paper discusses how positive thinking fosters optimism and resilience, while gratitude enhances appreciation and social bonds. A review of research highlights consistent, though modest, improvements in adolescents’ happiness, life satisfaction, and positive affect following structured interventions. Challenges in measurement, cultural adaptation, and program sustainability are also examined. The findings suggest that age-appropriate, culturally responsive, and ethically implemented gratitude and positive-thinking programs in schools can significantly promote emotional well-being and resilience among adolescents. Future research directions include longitudinal studies, cross-cultural validations, and digital intervention designs. |
