Fourteen percent of adolescents globally experience mental health issues, with parenting significantly impacting their physical and psychological well-being. A study conducted in Bheemdatt Municipality from September 15 to October 14, 2022, evaluated the relationship between parenting style and mental health among 583 school-going adolescents. Researchers assessed depression, anxiety, stress, and self-esteem using validated scales. Findings revealed that 37.39% of participants reported depression, 42.19% anxiety, and 24.69% stress, with an average self-esteem score of 22.26. An authoritative parenting style positively correlated with better mental health outcomes, while authoritarian parenting linked to higher depression and lower self-esteem. The permissive style was associated with increased stress. Factors such as social support and experiences of bullying significantly affected mental health results. The study emphasizes the importance of parental involvement and advocates for positive parenting practices to enhance adolescents’ mental health. It recommends that schools implement programs to raise awareness about mental health, provide stress management resources, and enforce anti-bullying policies to support students effectively.
