"This study makes important contributions to our understanding of the potential benefits of parental leave policies by highlighting associations between paternity leave and parents' reports of relationship satisfaction and relationship conflict after a child's birth within the U.S.," said Richard Petts, a Ball State sociology professor who co-authored the study with Chris Knoester at Ohio State University. The report will soon by published online at the Journal of Marriage and Family.

"Results suggest that men using paternity leave and taking longer leaves correlate with mothers' reports of greater relationship satisfaction and pre-birth working mothers' reports of lower relationship conflict," Petts said. "As such, this study offers evidence that paternity leave may help to reduce gender inequalities and strengthen family relationships."
