This work focuses on a comprehensive population health perspective in addressing these conditions, with a particular emphasis on Attention-Deficit/Hyperactivity Disorder (ADHD). The presented chapters encompass a diverse range of research studies aimed at identifying barriers and facilitators to mental health access, introducing clinical protocols, understanding decision-making strategies, and exploring the impact of internal and external factors on treatment outcomes, all while considering the critical lens of health equity. Chapters 2 and 3 examine the implementation of a shared-care approach to ADHD treatment in the unique context of China, delving into the identification of both barriers and facilitators that influence the adoption and effectiveness of such an approach across different metropolitan areas of the country, and within different pediatric healthcare settings. Socio-cultural factors, healthcare infrastructure, and the role of stigma are explored to shed light on the challenges and opportunities in expanding access to quality care for children and adolescents with ADHD. Presenting an innovative clinical protocol, Chapter 4 introduces a shared decision-making approach to stimulant titration for ADHD treatment. By involving patients, parents, and healthcare providers in the decision-making process, the protocol aims to enhance treatment outcomes and adherence. The significance of patient autonomy and tailored interventions is discussed, emphasizing the need to empower individuals in their healthcare journeys. Building upon the findings of Chapter 4, Chapter 5 explores the reasons behind the limited clinical adoption of placebo-controlled stimulant titration interventions for ADHD. Chapter 5 investigates the ethical, methodological, and practical considerations that have hindered, (or in some cases enabled) its use as a clinical standard of care. Chapter 6 examines how different decision-making strategies employed in stimulant titration trials lead to varying recommended maintenance doses following the trials. Herein, a shared decision-making approach that emphasizes parental collaboration, an expert decision-making approach which mimics classical top-down medicine, and a computer-based approach using a ranked-choice voting algorithm are compared. Against the backdrop of the COVID-19 pandemic, Chapter 7 delves into the experiences of parents whose children have been diagnosed with mental health conditions. The study investigates challenges in accessing care, adapting to remote interventions, and addressing the exacerbated psychosocial stressors during the pandemic. Health equity is underscored as a central concern, as disparities in care access and support are magnified during times of crisis. Together, these works present a comprehensive exploration of child and adolescent mental health treatment from a population health perspective. The individual chapters collectively contribute to a deeper understanding of barriers, facilitators, protocols, decision-making strategies, and real-world challenges that healthcare users, practitioners, and organizational or system-level providers face, while emphasizing the critical role of health equity in shaping effective and inclusive interventions.enAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Collaborative CareShared Decision MakingHealth EquityChild and Adolescent Mental HealthStimulant TitrationAttention-Deficit/Hyperactivity DisorderPopulation HealthThesis
