The present study examines perceived acceptance from one’s ingroup (i.e., intragroup acceptance) and collective self-esteem among Latinos as a function of Spanish proficiency. Using a correlational design, Study 1 demonstrates that Latinos’ (n = 53) Spanish-speaking inability is associated with lower private regard, membership, and less felt similarity to other Latinos, which was explained in part by greater perceptions of intragroup rejection. Moreover, Study 1 results were not moderated by overall Latino identification. Utilizing an experimental design, Study 2 demonstrates that non-Spanish-speaking Latinos (n = 40) put in a situation wherein they must disclose their inability to speak Spanish to another Latino were less likely to categorize themselves as Latinos, reported lower collective self-esteem, and reported less connectedness to other Latinos. These findings are discussed within a broader model of intragroup acceptance and identification, whereby cultural practices serve as markers of credibility that aid in felt acceptance within ethnic minority communities. Implications for acculturation are discussed.
