There are three major controversies regarding personality development in middle adulthood:
1) Whether a midlife crisis truly exists or is a myth
2) Whether development is better explained by normative-crisis models or life events models
3) The debate around stability versus change in personality over time.
Relationships and family dynamics also impact development, as adults navigate marriage, divorce, empty nests, and caring for aging parents and adult children. Personality is marked by both stability and change during this period.
