The Personal Wellbeing Index (PWI) for Adults is a tool used to measure subjective wellbeing and life satisfaction across various life domains, including health, relationships, standard of living, personal safety, community connection, and overall life satisfaction. It provides insights into how individuals perceive their own quality of life and identifies key factors that contribute to overall wellbeing. The PWI is widely used by researchers, policymakers, and practitioners to assess wellbeing in different populations and guide interventions to enhance quality of life.
