Identity Processes in Adulthood: Theoretical and Methodological Challenges

Abstract

Abstract The study of identity development in adulthood presents a number of fascinating theoretical challenges, including the relationship of identity to physical, cognitive, emotional, and social functioning. Equally challenging is the measurement of identity processes throughout the adult years. In this article, we discuss a theoretical model that relates identity to experiences in adulthood and incorporates the processes of identity assimilation, identity accommodation, and identity balance. We present data examining the relationship between the Identity and Experiences Scale (IES), a 33-item self-report rating scale, and the Defense Mechanisms Inventory (Gleser & Ihilevich, 1969). Relationships of identity processes to hypothesized personality constructs, gender, and age are discussed and examined as a basis for elaborating more fully on the model and its measurement.
