PSYCHOMETRIC PROPERTIES OF MIDWIFE- MOTHER RELATIONSHIP SCALE IN DELIVERY ROOM (M.M.R.S)

There is lack of knowledge about features of midwife-mother relationship in
different condition and setting where the midwife has different levels of responsibility in terms of the
normal and high-risk pregnancy. This study aimed to develop a scale for evaluating the midwife- mother
relationship in delivery room.
Methods & Materials: This is a methodological research. Participants were 480 mothers who
hospitalized at post-partum ward in a university hospital of Arak, Iran in 2014. Preliminary item pool
was developed by qualitative part of the study and literature review. Target group determined the validity
of the instrument by using the impact item method. The validity of the questionnaire was determined
with content validity ratio (CVR), content validity index (CVI), face validity and exploratory factor
analysis. Reliability of the instrument was reported by Alpha Cronbach coefficient.
Results: In the qualitative phase 66-item of questionnaire was developed. Those with impact item index
over 1.5, CVR over 0.42, and CVI over 0.79 were considered as valid; while the rest were eliminated
resulting in a 48-item scale. Exploratory factor analysis loaded a 43-item with a four factor solution that
jointly accounted for 60.4% of observed variance. Cronbach’s alpha coefficient showed excellent
internal consistency (α=0.93).
Conclusion: The findings showed that the designed questionnaire was a valid and reliable instrument
for measuring midwife- mother relationship in delivery room. It is easy to use the scale, and it contains
the most significant features of midwife-mother relationship
