This mixed-methods study is based on focus groups with over 100 women in four states with operating programs and a secondary analysis of Pregnancy Risk Assessment Monitoring System (PRAMS) data. It presents evidence of how PFL may facilitate longer leave that possibly leads to improved mental health outcomes by providing more time at home. It also demonstrates that PFL may directly support mental health by providing women with increased financial security and work/life boundaries. Implications of PFL design features on access and shortcomings are also discussed. These results aim to inform national or additional state-level PFL programs that may benefit working women, their families, and their employers.
