The International Society for Self and Identity (ISSI) is a scholarly association dedicated to promoting the scientific study of the human self. The Society members come from all over the globe, representing many different academic and professional disciplines. The members of ISSI share an interest in cognitive, emotional, and behavioral processes related to the self-system. These include the ability for people to think consciously about themselves, to form images and concepts of what they are like, to evaluate their characteristics and capabilities, to plan deliberately for the future, to worry about how they are being perceived by others, and to direct their own behavior in line with personal standards. Because this ability to self-reflect has important implications for understanding behavior, the self has emerged as a central focus of theory and research in many domains of social and behavioral science.

The official journal of ISSI is Self and Identity, which is published by Psychology Press. Self and Identity is a peer-reviewed academic journal that focuses on research and theory relevant to the aims of the society.
