The research titled “The Level of Peer Pressure in Adolescents in Relation to Demographic Variables in Kathmandu Metropolitan City, Nepal” aimed to investigate the level of peer pressure experienced by adolescents in public and private education institutions and explored the influence of various demographic variables, including sex, age, and education level. The study collected data from a sample of 400 students (200 from public education institutions and 200 from private education institutions) using a quantitative research design, with a Chi-Square test to determine the association of the variables. Adolescent peer pressure was measured using the Peer Pressure Questionnaire (PPSQ), which consists of 25 questions. The results showed that adolescents experienced a moderate level of peer pressure, and most were able to stand their ground and resist the influence of peers. Overall, the level of peer pressure was slightly higher among higher secondary-level students compared to their counterparts. Additionally, no statistically significant differences were found between public and private education institutions, as students from both experienced similar levels of peer pressure.
