Abstract—This article explores the intricate relationship between parenting practices and externalizing behavioral problems in children, focusing on attention deficit hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), and conduct disorder (CD). Rooted in a bio-psychosocial perspective, the study investigates the influence of parental factors on the development of externalizing behaviors. It examines the impact of parenting practices on these issues. Empirical evidence reveals a strong association between negative parenting practices, such as poor supervision and harsh discipline, and the manifestation of externalizing behavioral problems. This article underscores the critical role of parental intervention, particularly through psychosocial parent training programs, in mitigating these issues. Findings suggest that positive parenting practices correlate with reduced behavioral problems, emphasizing the importance of a supportive family environment. The study concludes by highlighting the implications for social work professionals, advocating for tailored interventions, and emphasizing the interconnectedness of early childhood development with later life stages. This comprehensive analysis provides valuable insights for practitioner.
