In this chapter, we write from the colonized position and in support of strategies that can move the field of multicultural psychology toward decolonization of both research methods and key concepts. Indeed, we believe that what is often understood as multicultural psychology needs to be decolonized as well. To the extent that the multicultural movement privileges domestic issues in the United States, it fails to acknowledge the broader multicultural international context of colonization and oppression. In this chapter, we focus primarily on the methodological challenges faced by investigators working primarily with ethnocultural populations in the United States. Our thesis is that the key task at hand is engaging in decolonizing methodologies, as suggested by Smith (1999). The context of where people work and live is not inconsequential. For example, we work in Puerto Rico, a territory of the United States that was first colonized by Spain and later colonized by the United States as of 1898. It remains one of the last colonies of the Western hemisphere, and as such its political, economic, and social structures are subordinate to the United States. With few exceptions, the development of nearly all psychological research, training, and practice responds to broader historical, social, economic, and political forces (Bernal, 2006). Thus, it is with the critical lens of a subordinated position that we approach the issue of research methods.(PsycInfo Database Record (c) 2022 APA, all rights reserved)
