A strong therapeutic alliance is consistently related to successful outcomes in couple therapy. However, most of the research done on therapeutic alliance has been done among non-Latino White individuals and couples, failing to account for other ethnic minorities like Latinos. Latinos tend to share certain commonalities as opposed to non-Latino clients that may alter the relationship between alliance quality and relationship quality. This exploratory study was designed to understand whether Latino clients have higher initial levels of alliance and a stronger alliance-outcome relationship in couple therapy when compared to non-Latino White couples. The sample consisted of 567 couples seeking therapy to improve their relationship (99 Latino and 468 non-Latino White couples). A multigroup moderation model was used to test whether Latino ethnicity moderates the association between alliance quality at session four and relationship quality at the final session. Similar findings of the association previously established between alliance quality and relationship quality were found. Results indicated that there was no statistically significant difference between Latinos and non-Latino Whites on initial levels of alliance quality nor on the relationship between alliance quality and relationship quality.
