View Course Details
This course examines loneliness as a complex biopsychosocial phenomenon and significant public health challenge. Despite its prevalence across demographic boundaries, loneliness remains understudied in both psychological and medical contexts. The course provides a comprehensive analysis of loneliness through multiple theoretical frameworks, examining its unique characteristics as a subjective experience that transcends objective social circumstances. Students explore theoretical foundations and contemporary models of loneliness; neurobiological mechanisms and physiological consequences; psychological assessment methods and diagnostic considerations; cultural and sociological dimensions; relationships with chronic stress, depression, and mortality; evidence-based intervention strategies; and public health implications and policy approaches. Special attention is given to emerging research on how loneliness intersects with modern social dynamics, technology, and global events such as the COVID-19 pandemic. Students develop a sophisticated understanding of both individual and population-level approaches to addressing loneliness. The course integrates recent advances in social neuroscience, health psychology, and clinical research.
