The goal of this study was to construct a reliable and valid scale that assesses the work-life balance attitudes of millennial college women. The items that created the Future Work-Life Balance Attitudes Scale (FWLBAS) were based on the Kaleidoscope Career Model and proved similar to findings from a previous qualitative pilot study. The scale was administered to an online sample of 508 millennial college women in their senior year of college. The data were then analyzed via exploratory and confirmatory factor analyses, and internal consistency reliability estimates were generated. The scale showed high reliability. The exploratory and confirmatory factor analyses led to the development of three subscales, namely “defining working motherhood,” “work-life balance strategies,” and “influence of college personnel,” and revisions of the item content of the FWLBAS. This scale is the first work-life balance instrument of its kind focusing on the population of millennial college women.
