The present study explored the effects of attachment and acculturation on relationship satisfaction for Latino young adults in their current close friendships. The study included 287 Latino students attending four-year universities who possessed a close friendship with a non-family member. The results indicate that attachment but not acculturation predicts relationship satisfaction for Latino young adults, with secure individuals more satisfied in their close friendships. Women were more satisfied than men with friends of the same- and opposite-sex. Latinos with high acculturation possessed non-Latino friends. Previous studies suggest Latinos look more anxious on attachment scales. However, this study indicates that attachment as measured by the Experiences in Close Relationships Scale may accurately predict friendship satisfaction for this population. High quality close friendships lead to positive health and mental health outcomes for young adults. The implications, limitations and suggestions for further research are discussed.
