This study explored whether 3 culturally relevant variables (i.e., ethnic identity, familism, and enculturation) operated as sources of strength for 209 Mexican American women by buffering the relationship between their acculturation to the mainstream U.S. society and eating- and body-related concerns. In an effort to capture the underlying dimensions of women's eating- and body-related concerns, the authors used principal components analysis to identify 3 components: control concerns, restricted eating, and body dissatisfaction. As hypothesized, results from a series of hierarchical regressions suggested familism significantly buffered the links between acculturation to the mainstream U.S. society and all 3 eating- and body-related variables. However, enculturation did not moderate the associations, and ethnic identity moderated only the link between acculturation and restricted eating. (Contains 2 figures, 1 footnote and 2 tables.)
