Development and psychometric properties of Midwives' Knowledge and Practice Scale on Respectful Maternity Care (MKP-RMC).

Objective To develop a scale for evaluating knowledge and practice of midwives on Respectful Maternity Care (RMC). Methods An exploratory sequential mixed method study was conducted from January 2018 to July 2019 in two non-teaching public hospitals in Tehran, Iran. In the first part of the study, a literature review and qualitative study were carried out in order to develop the preliminary item pool. Then face, content and construct validity and reliability (internal consistency and test-retest) were assessed. Results The MKP-RMC scale has 23-item in knowledge and 23-item in practice section that loaded in three factors: Giving emotional support, providing safe care and preventing mistreatment. Exploratory factor analysis accounted for 43.47% and 58.62% of observed variance in knowledge and practice sections, respectively. The internal consistency and internal correlation coefficient of both section of MKP-RMC indicated acceptable reliability. Conclusion The MKP-RMC is a valid and reliable tool for measuring midwives' knowledge and practice of respectful care during labor and childbirth. The MKP-RMC could be used in maternity services to evaluate and improve quality of childbirth care through development of educational interventions for effective behavioral change. Confirmation of validity and reliability of translated version of the scale in other maternity care providers and different contexts is recommended.
