Validation of the Greek version of Mother's Autonomy in Decision Making (MADM) scale

Ensuring expectant mothers have the capacity to make well-informed decisions regarding their prenatal care, encompassing medical interventions, and birthing preferences are crucial for fostering favorable health outcomes for both mother and newborn. The Mother's Autonomy in Decision Making (MADM) scale serves as a commonly utilized tool for evaluating the autonomy of pregnant women in the decision-making processes related to prenatal care and childbirth. The aim of this study is to validate the MADM scale in women who had at least one home childbirth experience in Greece.

A retrospective online survey collected data from Greek women with home childbirth experience (January 2010 - December 2023). We utilized a self-administered questionnaire and the Greek version of the MADM scale.

The study included 162 women, predominantly of Greek nationality (94.4%) and residing in Attica (54%). The MADM scale showed a median score of 38. The confirmatory factor analysis indicated acceptable fit and reliability (comparative fit index, CFI=0.92; Tucker-Lewis index, TLI=0.91; root mean square error of approximation, RMSEA=0.07; Cronbach's α=0.92). Age correlated weakly negatively with the MADM scale score (Spearman's rho= -0.166, p=0.035). Additionally, women attending antenatal preparation courses with a midwife before their first home birth had higher MADM scores (median 39 vs 35, p=0.037).

The study underscores the importance of the MADM scale, demonstrating its reliability and validity for women living in Greece. Younger age and attending antenatal preparation courses with a midwife were associated with higher MADM scores, highlighting education's role in maternal autonomy.
