Although it is often assumed that different ethnic groups will have different patterns of marriage, this study found considerable similarity in couple types across four ethnic combinations of married couples (both Hispanic, both Caucasian, Hispanic Male-Caucasian Female, Hispanic Female-Caucasian Male).This study is based on ENRICH data used in a dissertation by Jeffery Garrett (2004) who found no significant differences between the four groups of couples on the major ENRICH scales (i.e. marital satisfaction, communication, conflict resolution).
