A conceptual framework for adult development is proposed, based on a synthesis of the literature on role theory and various age-related adult developmental theories. It is proposed that adult development may not be as linear, uniform, and age-related as has been suggested. An individual adult could be in varying developmental stages across the life roles. The four life roles can be described as relationship with self, relationship with work, relationship with others, and relationship with family. A life role is partially defined by the societal expectations of appropriate role behaviors. Specific behaviors and tasks can be identified as characteristics of each stage of the cycle of each life role. The developmental stages of a life role cycle are initiation, adaptation, reassessment, and reconciliation. Any individual adult redefines the life role by modifying self-perceptions and expectations for appropriate role behavior. It is concluded that a conceptual framework that acknowledges the complexity and diversity of adult life while at the same time offering a systematic method for assessment would assist educators and student service providers in designing and planning programs, instruction, and curricula to meet the needs of adult learners as well as those of the institution.
