Cultural continuity, identity, and resilience among Indigenous youth: Honoring the legacies of Michael Chandler and Christopher Lalonde.

This essay is an introduction to the thematic issue of in honor of the work of Michael Chandler and Christopher Lalonde, developmental psychologists who made essential contributions to the study of identity and wellness among Indigenous youth in Canada and internationally. We outline their major contributions and illustrate the ways their innovative theory and methods have inspired decades of research, including the recent work presented in this issue, which addresses four broad themes: (1) the importance of a developmental perspective in mental health research; (2) the role of individual and collective continuity of identity in suicide prevention and mental health promotion; (3) Indigenous perspectives on trauma and resilience; and (4) Indigenous knowledge and values as a basis for culturally adapted and culturally grounded mental health services and interventions.
