The evaluation of expectation and satisfaction of pregnant women with prenatal care in Primary Health Care, in the perception of the users, is an important strategy that contributes to the quality of prenatal care. This study aimed to evaluate the expectation and satisfaction of the pregnant women with prenatal care in Primary Health Care, through the application of the Brazilian version of the Patient Expectations and Satisfaction with Prenatal Care (PESPC) instrument. Data were collected in eight prenatal public health services in the city of Bauru, being six Basic Health Units (BHU) and two Family Health Units (FHU). Data collection was performed through individual interviews and search in medical records. 377 pregnant women participated in the study. For the statistical analysis of data, the statistical software SAS version 9 was used. The following analyzes were performed: descriptive statistics, analysis of the frequency of the instrument's items, verification of the association among qualitative variables by Fisher's Exact Test, association measurement of qualitative variables through simple logistic regression analysis in which the gross Odds Ratio was calculated with its respective 95% confidence intervals, and reliability analysis through the calculation of Cronbach's alpha. The level of significance was 0.05. The Brazilian version of the PESPC instrument, which has 41 items distributed in two domains (expectation and satisfaction), was used. It is a Likert type scale, with response options ranging from 1 "totally agree" to 6 "totally disagree". For the expectation, the possible interval is 12-72 and; for satisfaction, it is 29-174; the lowest values represent high expectation and satisfaction with prenatal care. The majority of the pregnant women were multiparous 288 (76.4%), with a mean age of 27 years, 237 (62.9%) were housewives, 215 (57.0%) of the participants had six or more prenatal consultations. A low expectation prevalence 279 (74%) and a high satisfaction (58.8%) of pregnant women with prenatal care were identified. The simple logistic regression association tests showed that, for the expectation domain, there was no relationship among the variables and, for the satisfaction domain, the variable "having used the same prenatal service" showed association and statistical significance (p = 0.0398, OR = 1.711; IC 95% CI = 1.03-2.82). By Student's t test, there were no differences between the two services (BHU and FHU) for the two domains of the instrument. Reliability demonstrated adequate values for internal consistency for the domains of the adapted version of the PESPC instrument (expectation α = 0.82; satisfaction α = 0.91). It was concluded that the evaluation of the expectation and satisfaction of pregnant women with prenatal care in Primary Health Care in Bauru resulted in a predominance of low expectation and high satisfaction with prenatal public health services for both models of services evaluated, BHU and FHU. The Brazilian version of the PESPC instrument was adequate to evaluate the ...
