Abstract
The present study explored whether acculturation, ethnic identity, and strength of faith predict quality of life among Portuguese Americans. The theoretical framework utilized to aid in the application of the findings was the MAIP model. The sample consisted of 387 participants, with a mean age of 45.39 (SD = 14.75). Nine standard multiple regression analyses were completed, which resulted in nine models. The results indicated that acculturation (i.e., Portuguese orientation and Anglo orientation), ethnic identity (i.e., commitment and exploration), and strength of faith were all predictors of quality of life among Portuguese Americans. In particular, Portuguese acculturation orientation and high levels of religious faith exhibited greater predictive power in relation to participants' quality of life concerning physical health, psychological health, social, economic, family, and spiritual domains. However, Anglo acculturation orientation was found to achieve greater predictive power in regards to environmental quality of life. Despite ethnic identity commitment and exploration showing statistical significance, its predictive power in comparison to the other independent variables was relatively lower. Implications of the present study suggest behavioral health professionals should consider the role of acculturation, ethnic identity, and faith among Portuguese American clients to provide culturally sensitive and appropriate care.
