The development of a maternal satisfaction scale for caesarean section.
Satisfaction has become an important outcome measure. The purpose of this study was to develop a valid, reliable maternal satisfaction scale for women undergoing caesarean section. After Research Ethics Board approval, each patient gave verbal consent. To ensure face validity, patients were interviewed before and after caesarean section. Interviewing until no new items were generated ensured content validity. A draft scale using a 7 point Likert scale was given to 115 patients. Items endorsed by less than 15% of patients were deleted. Item-total correlations, principal component and factor analysis were performed and items in factors with less than three items or complex loadings excluded. Correlating the new scale to a Visual Analogue Scale (VAS) for satisfaction assessed construct validity. Reliability, as measured by internal consistency, was tested using Cronbach's alpha. Twenty-five women were interviewed for item generation. Patients were both nulliparous and multiparous and all received regional anaesthesia for elective or non-emergent caesarean section. Six items of the 33 on the draft scale were excluded because of lack of endorsement. Five items were excluded after principal component and factor analysis and two after item-total correlations. The correlation between the scale total and the VAS was 0.48. Cronbach's alpha was 0.82 for the total scale. Maternal sense of control was the item most related to satisfaction. This scale provides more detailed information than a simple VAS. In the population studied, this tool was found to be a valid and reliable method for assessing maternal satisfaction in women undergoing non-emergent caesarean section.
