The traditional cultural values and changing attitudes of Puerto Rican families are examined in this literature review. Puerto Rican families are "enmeshed" in their relationships due to the pervasive influence of the extended family system, it is argued. In a review of migration patterns, first from Europe to Puerto Rico, and subsequently to the mainland United States, it is observed that acculturation takes place by the third generation, resulting in selective acquisition of traits. Changing attitudes of the younger generation in terms of specific family roles are discussed. Research findings from the island as well as the mainland are analyzed and assessed for their impact on negative stereotypes regarding the Puerto Rican family. The paper suggests a number of topics which researchers can study to help better understand the Puerto Rican family: (1) evaluation of the dynamics of acculturation and cultural change from a Puerto Rican man's perspective; (2) multicultural analysis of Hispanic families; (3) the socialization of Puerto Rican children and their families on the mainland; and (4) multicultural ecological perspective of the Puerto Rican family in terms of interaction with environment.
