Risk-taking behaviour among young adults has become a growing concern due to its potential impact on health, safety, and long-term wellbeing. The effect of parenting and peer interactions on risk-taking behaviour among young adults has also become a compelling field of inquiry, as it ties in with the subjects of developmental psychology, public health, and social policy. In the last decades, research has shifted in how parental or peer impacts have been studied discretely to more integrative models that examine their interaction among adolescent and young adult behaviors. Underscored by the alarming Malaysia statistics on juvenile offence cases and juvenile apprehensions in 2024, this study is significant to examine how these psychosocial variables influence the risk-taking tendencies among young adults particularly in the urban setting. Thus, to investigate the relationship between parenting styles, peer pressure, and risk-taking behaviour among young adults in Kuala Lumpur, a quantitative, cross-sectional survey design was employed. A total of 249 young adults aged 18–25 has been recruited using a purposive sampling from community across Kuala Lumpur. Standardized instruments from the Parental Authority Questionnaire (PAQ), Peer Pressure Questionnaire-Revised (PPQ-R), and the Domain-Specific Risk-Taking (DOSPERT) scales were used, and the data was analyzed using descriptive statistics and correlational analysis. The findings revealed significant gender differences, with male participants reporting a higher likelihood of engaging in risk-taking behaviours, while female participants perceived such behaviours as more dangerous. The results also showed that permissive parenting and peer pressure were significantly associated with a higher likelihood of engaging in risk-taking behaviours. Authoritarian parenting and peer pressure were also linked to lower perceptions of risk, suggesting that both parenting style and peer influence play important roles in shaping how young adults behave and assess danger. These findings underscore the need for promoting balanced parenting and helping young adults to critically evaluate peer-driven behaviour. Further study may extend the sample size to capture different cultural and regional dispositions and bring in psychological and sociological theories that would explain how parenting styles, interaction with peers and risky behaviour are interwoven. It is also worth investigating how risk-taking behaviour among urban youth is affected when they interact with their peers on digital media.
