The positive psychology movement has been influential in the development of research agendas that focus on positive psychological constructs and their benefits. Of these, life satisfaction has been studied as an antecedent, mediating, and outcome variable in a wide array of studies ranging from medicine and health to psychology, management science, and economics. The purpose of this book is to present research from around the world related to a wide range of life satisfaction issues. The book is loosely structured around 3 themes: adolescent life satisfaction, older adult life satisfaction, and income-related satisfaction issues.
