Objectives:to analyze the internal consistency of the evaluation instrument of the
adherence to the good practices of childbirth and birth care in the
professionals, through Cronbach’s Alpha Coefficient for each of the
dimensions and for the total instrument. Method:this is a descriptive and cross-sectional study performed in obstetric
centers of eleven public hospitals in the Federal District, with a
questionnaire applied to 261 professionals who worked in the delivery care.
Results:The study was attended by 261 professionals, 42.5% (111) nurses and 57.5%
(150) physicians. The reliability evaluation of the instrument by the
Cronbach Alfa resulted in 0.53, 0.78 and 0.76 for dimensions 1, 2 and 3,
after debugging that resulted in the exclusion of 11 items. Conclusions:the instrument obtained Cronbach’s alpha of 0.80. There is a need for
improvement in the items of dimension 1 that refer to attitudes, knowledge,
and practices of the organization of the network of care to gestation,
childbirth, and birth. However, it can be applied in the way it is used to
evaluate practices based on scientific evidence of childbirth care.
