Partners showed a statistically significant increase in the domains Communication and information (<em>p</em> = .012) and Organization (p = .012) after moving to SFRs. For mothers, only several statements within these domains showed a significant increase after transitioning to SFRs. In conclusion, parental satisfaction increased in specific domains after the transition from an OBU to SFR environment in a level III NICU.
