This chapter considers the potential development of indigenous psychologies for African diasporic populations in uniquely multicultural regions, namely, the Caribbean and Canada. Black Psychology, or more appropriately, African American psychology, has a specific historical and disciplinary identity within the broader field of psychology. There has, however, been less explicit attention given to what psychological theories and practice may look like for Black, Western diasporic populations that are outside of the United States. Compared to African American Psychology, Caribbean Psychology, which seeks to address the needs of Afro-Caribbean populations and other populations in the region, is in its infancy, with theoretical and practical frameworks not yet clearly articulated. Comparatively, a uniquely Black Canadian psychology has yet to be conceived. By examining the sociocultural, historical, and political contexts of these regions, this chapter outlines five guideposts for developing indigenous psychologies for people who self-identify as “Black” or Afro-Caribbean in the Caribbean and Canada. These include epistemological and ontological considerations, explicit considerations of social justice, and the incorporation of decolonial and intersectional frameworks in designing and carrying out research studies with these peoples.
