The aim of this study was to determine the content and face validity of the Mackey Childbirth Satisfaction Rating Scale (MCSRS) questionnaire cross-culturally adapted to Brazilian Portuguese.
The MCSRS is a questionnaire with 34 items related to childbirth satisfaction. The forward- and back-translated versions were compared with the original material, and 10 experts analyzed each item according to the following criteria: clarity, semantic equivalence, appropriateness, and cultural relevance. The final version was presented to 10 mothers for face validation to ensure the questionnaire would suit the target population.
The total of 34 items assessed by experts for clarity, semantic equivalence, appropriateness, and relevance showed positive agreement of 0.85, 0.92, 0.97 and 0.97; negative agreement of 0.13, 0.09, 0.04 and 0.04; and total agreement of 0.75; 0.85, 0.94 and 0.94, respectively. Multilevel linear modeling was applied with crossed random effects and with nested random effects for each judge. The intercept of each criterion was as follows: clarity, 0.87; semantic equivalence, 0.92; appropriateness, 0.96; and cultural relevance, 0.96. The overall mean of agreement was 92.8%. The face validity measurement yielded 80% of agreement on the items, all of them clearly understood.
The final version of the Brazilian Portuguese MCSRS questionnaire had face and content validity confirmed. This instrument of evaluation of maternal satisfaction during childbirth was validated to be applied in the Brazilian female population.

The aim of this study was to determine the expression of the immunohistochemical markers p16 and Ki-67 in cervical intraepithelial neoplasms and their influence on the level of agreement among different observers and for the same observer.
The study included 184 patients with cervical intraepithelial neoplasms previously confirmed through biopsies performed between 2005 and 2006. Three pathologists reviewed the biopsies by using hematoxylin-eosin staining to reach a consensus on the diagnosis. Subsequently, an immunohistochemical study analyzed the expression of p16 and Ki-67 in such cases.
The comparison among the reviewing pathologists revealed only moderate agreement (kappa = 0.44). The agreement improved when the differentiation of highgrade lesions (cervical intraepithelial neoplasm - CIN - 3) was analyzed (kappa = 0.59). p16 staining exhibited a high negative predictive value and sensitivity; however, the specificity was low. Overall, both qualitative and quantitative analyses of p16 and a quantitative analysis Ki-67 exhibited low accuracy. The agreement among diagnoses before immunohistochemistry was 0.47. The use of immunohistochemistry increased the agreement to 0.68.
Our study showed that the agreement among observers using traditional diagnostic criteria of cervical intraepithelial lesions can improve with the use of immunohistochemistry.
