Parenting style is a pattern of behavioural approaches used by a parent when interacting with their child, which significantly influences their lives. Parenting styles also significantly impact adolescent well-being across various aspects. Adolescence is a crucial stage of development, spanning the ages of 10-19, which is marked by rapid biological, psychological, and social changes. The study examines four parenting styles, such as authoritative, authoritarian, permissive, and neglectful, which are effects on adolescents' psychological, physical, social, emotional, and educational well-being. The study revealed that authoritative parenting style is characterised by warmth, responsiveness, and structured guidance, which consistently support positive outcomes in all areas of well-being. Conversely, authoritarian and permissive styles often result in adverse outcomes such as poorer mental health and diminished well-being. The study emphasises the significance of supportive family environments, open communication, and nurturing practices in promoting adolescents' well-being. The findings hold significant educational implications, emphasising the need for strong home-school partnerships and parental guidance programmes to enhance adolescent well-being. The study concludes by emphasising the profound impact of parenting styles on adolescent development and the crucial role of authoritative methods in promoting overall well-being.
