Health Psychology: A Lifespan Approach offers a comprehensive exploration of health psychology theory, issues, and applications through a lifespan lens. Its biopsychosocial approach and chronological organisation examine the interactions of health and illness from preconception through to older age, with each chapter focusing on a specific life stage and highlighting mind-body interactions, health behaviours, and relevant interventions. Emphasis is placed on lifecourse health trajectories and how early life experiences - particularly adversity and social inequalities - shape later health outcomes. Features include: * Case studies that demonstrate real-world applications of theory * 'Under the Microscope' boxes showcasing cutting-edge research * Key terms and curated further reading to reinforce and expand learning This essential textbook equips undergraduate and postgraduate students with the tools to understand and apply health psychology across the lifespan.
