Revisiting the Mackey Childbirth Satisfaction Rating Scale: Spanish adaptation, factor analysis, and sources of construct validity

BackgroundWomen's dissatisfaction with perinatal health care services is associated with poor postpartum outcomes for the mother and the baby. The Mackey Childbirth Satisfaction Rating Scale is a frequently used measure of women's childbirth satisfaction. However, its factor structure has been inconsistent across investigations. The goal of this study was to evaluate the psychometric properties of the scale (i.e., factor structure and sources of validity evidence).MethodsThis study is a descriptive prospective investigation. Participants included 106 pregnant women (mean age = 31.86, SD = 4.12) recruited from a public university hospital situated in South Madrid. Sources of construct validity of the Mackey were explored with the Women's View of Birth Labor Satisfaction Questionnaire. Sources of criterion validity were investigated with measures of pain (labor, delivery, and just after birth) and post-traumatic stress symptoms.ResultsMinor adaptations in item distribution resulted in an adequate fit of the original six-factor solution of the Mackey scale (i.e., oneself, the partner, the baby, the nurse, the physician, and overall satisfaction). Sources of validity evidence supported the construct and criterion validity of the scale.ConclusionsObtaining a psychometrically and conceptually sound factor solution is fundamental when validating a scale. With the present study, researchers and clinicians (e.g., midwives) will be able to measure women's childbirth satisfaction in a more robust manner. Both antecedents and consequences of satisfaction were found to correlate with several satisfaction subscales, which might help guide prevention programs in mother care in a more efficient way.
