This course introduces students to clinical psychology through an evidence-centered exploration of mental health, diagnosis, risk, and treatment. Using a project-based approach, students select a mental health topic of personal or disciplinary interest and work with real data to investigate questions relevant to practice, policy, and public understanding. The course emphasizes how evidence is generated, interpreted, and used to guide real-world decisions. Students examine evidence drawn from epidemiological studies to evaluate risk factors, and targets of intervention, while considering the policy implications of mental health research. Throughout the course, students develop skills in evidence-based reasoning and research literacy. By engaging with data, not just reading about it, students learn how psychological science informs decisions that shape mental health care and public policy, and how those decisions affect individuals and communities.
