Probing identity, integration and adaptation: Big questions, little answers

•Selected studies of identity, integration and adaptation are presented to address questions about the process and measurement of acculturation.•The significance of cultural context for the relationship between integration and adaptation is highlighted.•Recommendations are made for future research to shape the development of acculturation theory.

In Berry, 1990 and Berry, 1997 acculturation typology integration is defined by two core components – maintenance of traditional heritage culture and participation in the wider society. These components, underpinned by attitudes, behaviors and identities, are believed to contribute in an additive fashion to the psychological and sociocultural adaptation of immigrants and ethnic minorities, and international research has shown that integration generally leads to more positive outcomes than separation, assimilation or marginalization. This paper draws on an international program of research and describes four multi-method studies that raise and explore key questions about the process, assessment and context of integration and its relationship to adaptation. Three questions are posed for consideration: (1) How is the dynamic process of integration experienced and articulated by immigrants? (2) How do our conceptualization and measurement of identity as an aspect of heritage culture maintenance impact the additive model of integration and adaptation? and (3) Under what conditions does integration fail to be adaptive? Tentative answers are offered, and recommendations are made for future studies to guide the development of acculturation theory and research.
