This chapter provides an overview of a new theoretical framework that serves to integrate personality psychology and other fields, such as organizational behavior. The first section describes a structural model of personality that incorporates traits, motives, abilities, and narratives, with social roles. The second section describes basic patterns of continuity and change in personality and how this might be relevant to organizational behavior. The third section describes the ASTMA model of person-organization transaction (attraction, selection, transformation, manipulation, and attrition), which describes the primary transactions between personality and organizational experiences across the life course. The goal for the chapter is to build a bridge between modern personality psychology and organizational behavior, such that the two fields can better inform one another.
