The purpose of the study presented here was to examine whether a measure of femininity ideology, normed on largely white, middle-class samples of adolescent girls, could be verified among a sample of low-income Latina adolescents. The results revealed that the previously identified factor structure could not be confirmed for this sample, which brings the scales’ validity for use with low-income, Latina samples into question. These findings suggest that minority girls may interpret femininity ideologies differently than do white, middle-class girls and underscore the importance of examining the validity of measurement tools for use with diverse populations. They emphasize that improving measurement for diverse populations is needed to develop culturally responsive and relevant intervention strategies.
