The mission of the Society for Interpersonal Theory and Research (SITAR) is to encourage the development of theory and research in the field of interpersonal theory.

The Society is an international, multidisciplinary, scientific association devoted to interpersonal theory and research that is broadly informed by, but not limited to, the meta-constructs of agency and communion, and their implications for normal and abnormal psychology. By encouraging systematic theory and empirical research, the Society seeks to identify the universe of interpersonal constructs, articulate the dynamic processes and mechanisms underlying interpersonal behavior, and illuminate interconnections between the self and interpersonal relations.

The aims of the Society are (1) to encourage the development of this interdisciplinary theory and research, (2) to create and support a community of interpersonal scholars, (3) to foster the communication, understanding, and application of research findings and theoretical advances, and (4) to enhance the scientific and social value of interpersonal theory and research.

The Society provides the following services: four educational meetings per year, an active website, an active listserv, and an electronic newsletter. These activities promote the following goals: to communicate current theoretical developments, research ideas, methods, and findings; to encourage ongoing discussion of work in progress; and to facilitate collaborative and interdisciplinary research.
