What does it truly mean to be “healthy”? In this introductory topic, we challenge the traditional view of health as merely the absence of disease and instead embrace a dynamic biopsychocultural framework. You will explore how health definitions vary dramatically across global cultures and examine why diversity is an essential pillar of modern medicine. Crucially, we will ground our foundational learning in contemporary issues, analyzing how socio-cultural determinants uniquely shape the healthcare experiences, disparities, and resilience within transgender and gender-nonconforming communities. Finally, we will look at the evolution of health psychology as a discipline and map out the diverse career and graduate pathways available to you.
