The second edition will be an update and further elaboration of the literature related to subjective well-being, happiness, and life satisfaction. It will have a new substantial section that focuses on reviewing much of the literature of subjective well-being within specific life domains (social life, material life, leisure life, work life, community life, spiritual life, family life, health life, sex life, travel life, etc.) In the 1st edition the research in these various life domains was discussed only briefly. The second edition will maintain the same organizational structure of the first edition; that is, Part 1 will focus on introduction (definitions and distinctions; examples of measures of subjective well-being, happiness, and life satisfaction; and motives underlying subjective well-being). Part 2 will focus on psychological strategies that are allow people to optimize subjective well-being by engaging in psychological processes related to the relationship between and among life domains (e.g., social life, family life, love life, spiritual life, community life, financial life, etc.) This part will contain four chapters related to these various βinter-domainβ processes: bottom-up spillover, top-down spillover, horizontal spillover, and compensation. Part 3 of the book will focus on βintra-domainβ psychological strategies designed to optimize subjective well-being. These include re-evaluation based on personal history, re-evaluation based on self-concept, re-evaluation based on social comparison, goal selection, goal implementation and attainment, and re-appraisal. Part 4 of the book will focus on balance processesβhow people attempt to create balance in their lives using psychological processes within specific life domains (intra-domain strategies) and processes that relate one domain to another (inter-domain strategies).
