摘要:Abstract Although the “identity” term is used mainly in social psychology, in the present approach the “Identity Structures” concept (IS) represents a set of seven structures that plays the role of interfaces between the individual internal psychological world (having as a core the Self) and the social environment. The paper presents data regarding Identity Structures dynamics in two groups: one composed of middle-aged adults, the other consisting of older adults. It is also discussed the relation between Identity Structures and mental health.
