Mexican American women have higher fertility rates and higher divorce rates than does the general population of the United States. In light of these data and the documented negative effects of marital distress and divorce on spouses, Mexican American women appear to be at risk for psychological stress. To provide some insight into the marital problems of Mexican American women, the relationship of interethnically and intraethnically married Mexican American women was compared in terms of cultural background or level of acculturation, level of marital satifaction, and marital problems. Interculturally married Mexican American women (N=15) married to Anglo American men and intraethnically married Mexican American women (N=12) married to Mexican American men participated in individual interviews and completed: (1) an acculturation questionnaire that assessed their level of identification with the Mexican American culture and with the Anglo American culture; (2) a Problem Inventory that asked them to identify problems in their marriages due to cultural differences; and (3) a marital satisfaction questionnaire. The results revealed that, compared to intraethnically married women, interethnically married women were more acculturated toward the Anglo American culture than toward the Mexican American culture and showed a trend that asked them to identify problems in their marriages due to cultural differences, and (3) a marital toward a higher level of marital satisfaction. Correlational analyses revealed that for both groups, levels of acculturation were significantly correlated to marital problems, marital satisfaction, and social support systems. The results also provided evidence for a greater degree of traditionality in the intraethnic marriages, consequently leading to marital distress and dissatisfaction. (Author/NRB)
