Adherence to treatment regimens is crucial for effective disease management but is often hindered by various psychosocial and socioeconomic barriers. Parental mental health issues, family dynamics, financial constraints, and limited access to specialized care contribute to inconsistent treatment adherence, exacerbating the condition. Purpose/Aim: The aim of this study is to explore the multifaceted barriers to treatment adherence in children with AD and evaluate the effectiveness of current interventions targeting these challenges. The study seeks to identify strategies that can improve adherence and health outcomes by addressing psychosocial and socioeconomic factors. Method: The method involves a comprehensive review of existing literature on the impact of psychosocial and socioeconomic factors on treatment adherence in children with AD. The study also examines various interventions designed to address these barriers, including community support programs, family-centered interventions, financial aid, integrated care models, and telehealth solutions. Results: Results indicate that psychosocial barriers, such as parental anxiety and depression, significantly hinder effective disease management. Family dynamics, including poor communication and single-parent households, complicate adherence efforts. Socioeconomic factors, such as financial constraints and limited healthcare access, further impede adherence. Interventions that address these barriers show promise in improving treatment adherence and health outcomes. Community support programs and family-centered interventions enhance parental mental health and family communication. Financial aid programs and integrated care models help mitigate economic and logistical challenges. Telehealth solutions improve access to specialized care, particularly in underserved areas. Conclusion: The study concludes that a holistic approach integrating medical treatment with psychosocial and socioeconomic support is essential for managing pediatric AD effectively. Policy recommendations include increased funding for community support programs, expanded telehealth services, and the integration of social services with medical care. Addressing these barriers comprehensively can enhance treatment adherence and improve the quality of life for children with AD. Further research should focus on long-term outcomes and diverse populations to refine these interventions and ensure they meet the needs of all affected children.展开更多
