BACKGROUND: Continuity of midwifery care has been proven to show an improvement in clinical outcomes for women and greater maternal satisfaction with maternity care. Several questionnaires have been developed to measure satisfaction with maternity services although few are suitable for continuity of midwifery maternity care models, and many have not been validated.

AIMS: The purpose of this study was to test the reliability and validity of the newly developed Continuity of Midwifery Care Satisfaction Survey (COMcareSS) with a cohort of women who have recently experienced continuity of midwifery care.

METHODS: The COMcareSS was distributed to women in Australia who had experienced a live birth within a continuity model of midwifery care and were up to two months postpartum. Factor analysis was conducted, and Cronbach's alpha coefficient calculated for the 34-item scale.

FINDINGS: In total 272 completed responses were recorded. Cronbach's alpha coefficient for the scale was 0.96 suggesting some redundancy in items. There was a lack of variation in responses. In factor analysis, only one factor could feasibly be attempted. This accounted for 76 % of variation in responses.

CONCLUSION: The COMcareSS scale is the first to be developed to measure maternal satisfaction with continuity of midwifery led care. The 34-item scale has good internal consistency. The scale may be unidimensional though the lack of variation in responses means that other possible latent constructs, were not able to be detected. Use of a standardised scale such as the COMcareSS will facilitate benchmarking between services and, comparison and meta-analysis in research studies.
