Maternal and child health has been a priority public health issue for decades and is internationally considered one of the best measures for assessing the quality of healthcare. Currently, health systems are moving towards high-value care tailored to each individual patient. Patient satisfaction is generally an important indicator of the quality of care provided. Based on patient satisfaction results, measures can be taken to improve services. One way in which patient satisfaction can be assessed is through the development and application of satisfaction measurement tools (1).
As in other disciplines, perinatal care can benefit from systematic evaluation of patient-reported experience measures to improve the quality of care. Assessing women’s satisfaction with childbirth is a complex task that is increasingly important for healthcare providers, administrators and policy makers. It is essential to take into account women’s views and experiences in order to make improvements in midwifery care and ensure a positive experience for mothers and newborns. The most common way of assessing women’s satisfaction with childbirth is through the use of questionnaires (2). Questionnaires provide an effective way of obtaining information about patient experience and allow for comparison.
As birth satisfaction is a multidimensional construct, the instruments used to measure it are also very heterogeneous. The inconsistent approach to assessing women’s satisfaction with childbirth complicates the possibilities of comparison, both within a health system in one country and internationally. Authors of birth satisfaction questionnaires often focus only on some aspects of satisfaction, rather than on satisfaction as a whole. Moreover, it is evident that many questionnaires used to measure satisfaction with maternity care have not been thoroughly developed or tested (3, 4).
In 2017, two systematic reviews on instruments measuring women’s satisfaction with childbirth were published by Nilvér et al. (5) and Blazquez et al. (2). The authors focused on assessing instruments used to measure women’s satisfaction with care during childbirth related to the construction, reliability and validity of these instruments. The first review (5) analysed and evaluated thirty-six measurement tools and the second review (2) presented seventeen tools. The recommendations arising from these two studies are broadly similar. Both review studies (5, 2) emphasise the importance of identifying and assessing women’s experiences and satisfaction with childbirth. Knowing and respecting the needs of patients (birth mothers) plays a very important role in the process of improving maternal and child care. They point out that despite the fact that there is a wide range of tools available to measure women’s satisfaction with their birthing experience, there is great variation in their quality. Given the large number of instruments used in the literature and the lack of complete testing of many of them, the authors of the review studies recommend that researchers should not continue to develop new instruments but should seek to thoroughly test, adapt and improve those that already exist. When different instruments are used to measure the same construct of interest, it can be difficult to compare results in systematic reviews.
The aim of the literature review is:
to identify currently available instruments measuring women’s satisfaction with childbirth; to evaluate, compare and summarise their structure, content and psychometric properties.
The design of the literature review was adopted. The conduct of this literature review followed the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidance for completing systematic reviews of patient-reported outcome measures (6), adapted as necessary to suit this review.
Women’s satisfaction with childbirth
This review includes all studies in which women participated after childbirth, regardless of weeks of pregnancy, mode of delivery or number of children.
Studies in which participants were partners of women or health professionals were excluded.
This review includes full text articles in English.
This review includes validation studies.
Included are studies that reported psychometric properties related to the development, validity and reliability of instruments (questionnaires, scales) used to measure women’s satisfaction with childbirth.
Excluded studies were: case report or series, systematic review, meta-analysis, if an instrument was being used within a randomised trial or alternative study, or if the instrument was being used as part of the validation process of an alternative instrument.
Studies reporting instruments measuring women’s satisfaction with a specific birth situation (women’s satisfaction in preterm birth, after caesarean section, etc.) not related to the phenomenon of ‘satisfaction’ (instruments developed solely to measure specific concepts such as fear, anxiety, self-efficacy, etc.) were excluded. Studies using unidimensional instruments were also excluded.
A systematic search for studies was conducted to identify and locate relevant sources. All screening was completed by two reviewers independently (KR and JH; midwives with >15 years’ experience and also researchers with >10 years’ experience) and disagreements resolved through face to face discussion. Searches were conducted in Web of Science, Medline/PubMed, EBSCOhost, Science Direct, CINAHL, Wiley, Springer and ProQuest databases. Studies published in Czech or English in the period 2018–2022 were searched: “delivery” OR “lab*r” OR “birth” OR “childbirth” AND “validation” AND “questionnaire” OR “scale” OR “instrument” AND “women’s satisfaction” OR “experience” OR “perception”.
The identification and selection of research studies for this review are described in the PRISMA flow chart (Figure 1).
The psychometric properties of the measurement instruments were assessed according to the principles of the COSMIN methodology (6). Content validity, structural validity, internal consistency, reliability and cross-cultural validity were assessed. Three reviewers (KR, JH, PM – statistician and analyst) were involved in assessing the psychometric properties of the questionnaires. Results were evaluated once by each rater and inter-rater agreement was observed; any differences were resolved by discussion. Inter-rater reliability was ensured by strict adherence to the COSMIN manual for systematic reviews of PROMs (6, p. 28–32).
Thirty-one studies were included in the review (Table 1), reporting the psychometric properties of six measurement instruments (questionnaires, scales). Only one study (7) aimed to develop and validate a new measurement instrument of satisfaction with childbirth. Most researchers focused on existing instruments measuring women’s satisfaction with childbirth, which is consistent with the recommendations of the authors of previous review studies (2, 5). The aim of the studies was to translate, adapt and validate the already existing instruments in a new cultural and social setting. Five original measurement tools were adapted and validated in 21 countries.
All adaptations of measurement tools into a foreign language were done according to standards, most often by back-translation, expert review and pre-test (N=10–50). The structure and content of the questionnaires varied. They contain 3 to 10 different dimensions/factors and 10 to 52 items (Table 1). The items in the questionnaires were rated on a four to seven point Likert scale. The CEQ/CEQ2 questionnaire has some items rated on a visual analogue scale (12, 23).
The most frequently reported dimension was satisfaction with healthcare providers (perception of midwifery care and professional support, satisfaction with midwife, obstetrician, relationship with staff, quality of care provided). Other frequent dimensions reported were satisfaction focused on the woman herself (her emotions, perceptions of pain, feelings of safety, control, expectations, ability to participate in decision-making), support from loved ones (partner or other person present), the baby (contact, bonding) and the environment (Table 2).
Most studies have focused on women a few days to a few months postpartum, up to 5 years postpartum (37).

Content validity is the most important property of measurement tools. The content validity of measurement tools was assessed according to the COSMIN methodology (6). Clarity is one of the components of content validity. All the translated tools used in our review were pilot tested on the target population, which is a condition for inclusion of a study in the review (6). Face validity was performed for all studies. We report the assessment of the psychometric properties of each measurement tool according to the COSMIN manual for systematic reviews of PROMs (6, p. 28–29) in Table 3.

The aim of this review was to identify, describe and evaluate instruments measuring women’s satisfaction with childbirth. The World Health Organization (WHO) emphasized the importance of women’s positive experience of childbirth in its recent document “Intrapartum care for a positive childbirth experience” (42). The importance of woman-centred care, whereby the quality of perinatal care is optimized through a holistic, human rights-based approach, is emphasised. Measuring women’s satisfaction with childbirth requires valid, reliable and multidimensional tools (31).
The most commonly used questionnaires in research studies have been the Childbirth Experience Questionnaire (CEQ/CEQ2) and the Birth Satisfaction Scale-Revised (BSS-R).
The CEQ2 shows excellent psychometric properties in the study by Walker et al. (25). It contains 22 items that are rated on a 4-point Likert Scale, and three items are rated on a visual analogue scale. The CEQ2 is easy to understand and easy to complete. Items in the questionnaire focus on, for example, the woman’s feelings during labour, particularly her sense of security, the midwife’s behaviour, memories of the birth and the opportunity for shared decision-making during labour. The results of the questionnaire differ significantly between groups of women with different birth experiences (e.g., lower satisfaction among women with operative delivery, delivery longer than 12 hours, delivery with oxytocin augmentation) (23).
The BSS-R is a valid, reliable instrument to measure women’s satisfaction after childbirth, which can be easily and quickly completed by women, with only ten items rated on a 5-point Likert Scale. The content of the questionnaire focuses on, for example, feelings of anxiety and stress during childbirth, support from staff, co-decision making, sense of control, as well as the birth itself (length, injuries). In studies by Martin et al. (31), Nasiri et al. (32), Radoš et al. (38) and Ratislavová et al. (41), the scale has excellent psychometric results. Future studies need to focus on testing the stability and reliability of an instrument over time.
The BSS-R scale is currently recommended by the International Consortium for Health Outcomes Measurement (ICHOM) as the main tool for measuring women’s experiences of childbirth (43). ICHOM recommends that all obstetric care providers worldwide begin to measure satisfaction with childbirth using the BSS-R to better understand how to improve the lives of their clients. The BSS-R has been used in 39 countries and 134 sites worldwide in 2020 (44). Hollins Martin and Martin founded the Birth Satisfaction Consortium, which brings together researchers and professionals who work in perinatal care research and delivery. The consortium aims to (45): Translate and validate the BSS-R for use in different populations and cultures and make these versions available for use; Collecting data from around the world on women’s experiences and satisfaction with childbirth to improve the delivery of maternity care; Identifying risk (negative) and protective (positive) factors associated with the experience of childbirth in different cultural contexts; Opportunities to consult on preventive strategies to minimize the impact of psychological trauma during childbirth in different cultural contexts; Dissemination and sharing of research findings to maternity care professionals and the general public.
In terms of the limitations affecting this review, it should be noted that only studies published in English were assessed, relatively strict inclusion criteria were applied, and additional tools may have been validated during the time we were conducting the review. Therefore, some instruments may not have been identified. In the process of assessing the psychometric properties of the questionnaires, the selection of raters/reviewers should be mentioned. Evaluating the relevance, comprehensiveness and clarity of the included studies with respect to the construct of interest and the study population requires very good expertise. Assessing the validity of measurement instruments requires knowledge of statistical methods and procedures, as well as the subjective judgment of reviewers. The erudition of the reviewers is important and should always be mentioned when presenting results for individual studies (46). We assembled our review team with an awareness of the importance of the expert erudition of the reviewers.
Thorough testing of instruments measuring women’s satisfaction with childbirth, and adapting them to cultural and social contexts, is essential. Our study highlights two important and high-quality instruments that have been adapted and translated into a number of languages. This allows us to assess the quality of care provided in different countries, but also to identify cultural differences and the impact of different healthcare delivery systems on women’s satisfaction with childbirth. Research suggests that monitoring women’s satisfaction with childbirth gives women the opportunity to engage in perinatal care, contributes to improving the quality of care provided, and may play a role in avoiding litigation and maintaining competitive advantages for healthcare facilities whose clients are satisfied (47). It is essential that valid and reliable questionnaires are available for midwives in practice, for use in research, to inform clinical sites, and that the results help to develop the services offered.
