Abstract

Manager attitude is influential in female employees' perceptions of workplace breastfeeding support. Currently, no instrument is available to assess manager attitude toward supporting women who wish to combine breastfeeding with work. We developed and piloted an instrument to measure manager attitudes toward workplace breastfeeding support entitled the "Managers' Attitude Toward Breastfeeding Support Questionnaire," an instrument that measures four constructs using 60 items that are rated agree/disagree on a 4-point Likert rating scale. We established the content validity of the Managers' Attitude Toward Breastfeeding Support Questionnaire measures through expert content review (n=22), expert assessment of item fit (n=11), and cognitive interviews (n=8). Data were collected from a purposive sample of 185 front-line managers who had experience supervising female employees, and responses were scaled using the Multidimensional Random Coefficients Multinomial Logit Model. Dimensionality analyses supported the proposed four-construct model. Reliability ranged from 0.75 to 0.86, and correlations between the constructs were moderately strong (0.47 to 0.71). Four items in two constructs exhibited model-to-data misfit and/or a low score-measure correlation. One item was revised and the other three items were retained in the Managers' Attitude Toward Breastfeeding Support Questionnaire. Findings of this study suggest that the Managers' Attitude Toward Breastfeeding Support Questionnaire measures are reliable and valid indicators of manager attitude toward workplace breastfeeding support, and future research should be conducted to establish external validity. The Managers' Attitude Toward Breastfeeding Support Questionnaire could be used to collect data in a standardized manner within and across companies to measure and compare manager attitudes toward supporting breastfeeding. Organizations can subsequently develop targeted strategies to improve support for breastfeeding employees through efforts influencing managerial attitude.
