Which psychological concept describes the older adult's sense of fulfillment in life and acceptance?

The concept that reflects an older adult's sense of fulfillment in life and acceptance is integrity. This term is rooted in Erik Erikson's psychosocial development theory, specifically in the stage called "integrity vs. despair," which typically occurs during late adulthood. In this stage, individuals review their lives and feel a sense of satisfaction or fulfillment if they believe they have lived meaningfully and made valuable contributions. When a person achieves integrity, they are able to look back on their life without regrets, embracing their experiences and choices.

Integrity allows older adults to accept the past, including both successes and failures, fostering a sense of wisdom. This acceptance contributes to overall psychological well-being, enabling them to face the end of life with a sense of peace and completeness.
