Stage 6 of Erikson's Theory of Psychosocial Development

The sixth stage of psychosocial development, intimacy versus isolation, occurs during early adulthood, from approximately ages 19 to 29. A crucial prerequisite for this stage is a well-developed sense of self, established during adolescence. With a strong identity, individuals are prepared to form deep, intimate relationships and share their lives with others. Conversely, adults who did not successfully form a positive self-concept in the previous stage may struggle with feelings of loneliness and emotional isolation.
