As an immigrant population becomes more prominent in an established culture, research strategies for examining intragroup differences are needed to understand their health care risks and strengths. However, acculturation also must be taken into account. Our objective in this secondary analysis was to identify the most useful acculturation parameter for examining depressive symptoms in relation to strengths and resources among women of Mexican descent living in the United States during the vulnerable perinatal period and to examine other intragroup differences among the women by childbearing status (pregnant or postpartum). Our secondary analysis was done with a subsample of 129 women from a larger cross-sectional study of 315 women of Mexican descent who were recruited from three urban community health centers and an associated bilingual school in the United States. Exposure to the United States in childhood, a poor sense of mastery, and dissatisfaction with life were more related to depressive symptom experience than childbearing status or more traditional demographic variables such as age, income, or education.

Although intrinsic strength factors have rarely been included in research related to depression in women of Mexican descent, they were more directly related to lack of depressive symptoms than traditional demographic risk factors.

The purpose of this study is to test the reliability and validity of a Spanish translation of the Resilience Scale (RS), which was originally created in English by Wagnild and Young (1993). A team of bilingual, bicultural translators participated in the translation process to enhance the linguistic accuracy and cultural appropriateness of the Spanish translation. As part of the convenience sample of 315 women of Mexican descent who participated in the larger study, data from 147 women who preferred to read and write in Spanish were used in this analysis. The English version of the RS consists of a 17-item "Personal Competence" subscale and an 8-item "Acceptance of Self and Life" subscale for a total of 25 items. However, two items had low item-total loadings and were removed to form a modified 23-item RS. The exploratory principal components factor analysis, varimax rotation, and subsequent goodness of fit indices were ambivalent on whether a one or two-factor solution was appropriate, but the chi-square difference test clearly demonstrated that the two-factor solution of the Spanish version was more useful in explaining variance than a one-factor solution. Internal consistency reliability was estimated with Cronbach's alpha (alpha = 0.93) which was acceptable for the 23-item RS as well as its subscales. Construct validity was demonstrated by a significant positive correlation between resilience and life satisfaction (r = 0.36; p < 0.001), and a significant negative correlation between resilience and depressive symptoms (r = -0.29; p < 0.01). This analysis ultimately supports the appropriateness of the modified 23-item Spanish translation of the RS and its subscales in a sample of urban, low-income women of Mexican descent in the U.S.
