Abstract
Although the study of midlife has increased somewhat over the last decade, middle-aged adults are often omitted from research on adult development and aging. Possible reasons for the lack of attention to middle age are considered and recommendations for ways to increase research on midlife are suggested to generate new knowledge and to dispel the myths. Findings related to the happiness curve and the midlife crisis are discussed in the context of addressing misconceptions. A model of midlife as a pivotal period in the life course at the intersection of growth and decline is presented. Closing the research gap in the middle of the life course will help to further our understanding of this understudied age period. The findings can inform interventions to promote well-being among the middle-aged with concomitant benefits for the welfare of those younger and older who depend on them.
