The effects of ethnicity, education and an informational video on pregnant women's knowledge and decisions about a prenatal diagnostic screening test

Genetic counseling processes and strategies for racially and ethnically diverse populations: A systematic review

Genetic counseling outcomes are influenced by the processes and strategies used by counselors, yet little is known about how these strategies directly impact patients and populations. In particular, tailoring genetic counseling consultations to best meet the needs of cultural, racial, and ethnically diverse populations has been explored. This review aims to identify genetic counseling strategies tailored for a diversity of racial and ethnic populations with the goal to find ways to improve genetic counseling outcomes. Medline, Cochrane CENTRAL, Embase, PsychInfo, and CINAHL databases were searched for original research articles published in English that employed genetic counseling processes and strategies to improve genetic counseling outcomes, specifically for participants from ethnically or racially diverse populations. A review of 5300 titles and abstracts resulted in the identification of 36 articles that met the inclusion criteria. Three themes emerged: (1) community involvement in culturally tailoring genetic counseling, (2) creation and use of culturally tailored resources, and (3) modifications to the genetic counseling process. The effectiveness of genetic counseling strategies could not be evaluated due to lack of consistent outcome measures in the articles. The involvement of diverse ethnic and racial populations in developing inclusive genetic counseling tools and practices will help the profession provide better patient care in the future. More research connecting genetic counseling processes and outcomes will help to assess how well these modified approaches meet the needs of diverse populations.

Latinx individuals' knowledge of, preferences for, and experiences with prenatal genetic testing: a scoping review

BACKGROUND

The American College of Obstetricians and Gynecologists recommends prenatal genetic testing (PGT) be offered to all pregnant persons regardless of known risk factors. However, significant racial/ethnic differences exist regarding acceptance of PGT contributing to disparities. Latinas (Latinx), one of the fastest growing ethnic groups in the United States, have low PGT acceptance rates. This systematic scoping review aimed to provide a landscape of existing literature on Latinx individuals' knowledge of, preferences for, and experiences with prenatal and preconception genetic testing. Synthesizing the current state of the science may inform development of culturally tailored interventions to support high-quality PGT decisions (e.g., informed, aligned with a pregnant persons' values).

METHODS

We conducted a structured, systematic literature search of published articles and gray literature in electronic databases (PubMed, PsycINFO, CINAHL, Medline, Embase, Eric, Social Services Abstracts, and PsycArticles). Articles in English published prior to March 2021 were retrieved relating to genetics, pregnancy, and Latina women. Articles underwent title, abstract and full-text review by independent investigators to assess inclusion and exclusion criteria. Risk of bias was evaluated by two investigators. Iterative thematic analysis was employed to group study findings into themes to identify possible targets for interventions.

RESULTS

The search generated 5511 unique articles. After title screening, 335 underwent abstract review and subsequently 61 full-text review. Twenty-eight studies met inclusion criteria and 7 additional studies were included after reviewing reference lists. Three overarching themes emerged: genetic knowledge/literacy (26/35, 74%), provider (mis)communication/patient satisfaction (21/35, 60%), and cross-cultural beliefs (12/35, 34%). Studies indicate discordant patient-provider language (n = 5), miscommunication (n = 4), and lack of concordant decision-making (n = 4) pose barriers to high-quality PGT decisions. Immigration status (n = 1) and religious beliefs (n = 5) are additional factors influencing PGT decisions.

CONCLUSIONS

Identified studies suggest that cultural and linguistic factors affect Latinx PGT decision-making. Latinx individual's comprehension and recall of PGT information is enhanced by culturally and linguistically concordant providers-suggesting that culturally-informed interventions may enhance PGT acceptability and support high-quality decisions. Future directions to surmount PGT disparities may include community health workers and cultural brokers to empower Latinx people to make informed decisions aligned with their values and preferences.

The use of video for patient information and education: A scoping review of the variability and effectiveness of interventions

OBJECTIVE

To provide an overview of video interventions used for patient information and education, and of the tools used to evaluate their effectiveness, in order to consider the feasibility of developing generic guidelines and appraisal tools for the use of video in patient care.

METHODS

A scoping review was carried out to describe and synthesise emerging knowledge, using thematic analysis of data. Studies focussed upon videos for health professional education were excluded, as were those which consider the impact of videos available via social media.

RESULTS

A narrative overview of 65 identified papers provides insight into the range and scope of studies. Common themes emerge, notably the aim of reducing anxiety and the variety of instruments designed to measure this. The use of self-report questionnaires was common, but their design is variable.

CONCLUSION

Targeted video-based intervention can improve patient experience and outcomes. High utility guidelines and appraisal tools, transferable between contexts, are needed to facilitate deployments at scale for sustainable outcomes.

PRACTICE IMPLICATIONS

Video production guidelines and appraisal tools will be of value to those engaged in video development and deployment. Guidance should be based upon emerging evidence of effectiveness and incorporate an emphasis on reusability.

Feasibility of Two Educational Methods for Teaching New Mothers: A Pilot Study

BACKGROUND

Printed health educational materials are commonly issued to prepare patients for hospital discharge. Teaching methods that engage multiple senses have been shown to positively affect learning outcomes, suggesting that paper materials may not be the most effective approach when educating new mothers. In addition, many written patient educational materials do not meet national health literacy guidelines. Videos that stimulate visual and auditory senses provide an alternative, potentially more effective, strategy for delivering health information. The acceptability of these methods, as perceived by nurses executing patient education initiatives, is important for determining the most appropriate strategy.

OBJECTIVE

The purpose of this study was to determine the feasibility of 2 educational methods for teaching new mothers how to care for themselves and their infants after hospital discharge. Feasibility was measured by adequate enrollment, acceptability of the intervention to patients and nurses, and initial efficacy.

METHODS

New mothers (n=98) on a Mother-Baby Unit received health information focused on self-care and infant care delivered as either simple printed materials or YouTube videos on an iPad. Mothers completed a pretest, post-test, and an acceptability survey. Following completion of the initiative, nurses who participated in delivering the health education using one of these 2 methods were asked to complete a survey to determine their satisfaction with and confidence in using the materials.

RESULTS

Mothers, on average, were 26 years old; 72% had a high school education; and 41% were African American. The improvement in knowledge scores was significantly higher for the iPad group (8.6% vs 4.4%, P=.02) compared to the pamphlet group. Group (B=4.81, P=.36) and time (B=6.12, P<.001) significantly affected scores, while no significant interaction effect was observed (B=5.69, P=.09). There were no significant differences in responses between the groups (all P values >.05). The nurses had a mean age of 44.3 years (SD 13.9) and had, on average, 16.6 years of experience (SD 13.8). The nurses felt confident and satisfied administering both educational modalities.

CONCLUSIONS

The pamphlet and iPad were identified as feasible and acceptable modalities for educating new mothers about self-care and infant care, though the iPad was more effective in improving knowledge. Understanding the acceptability of different teaching methods to patient educators is important for successful delivery of informational materials at discharge.

A systematic review of issues around antenatal screening and prenatal diagnostic testing for genetic disorders: women of Asian origin in western countries

Antenatal screening has become standard practice in many countries. However, not all pregnant women choose to be tested. In the UK, the incidence of some birth defects is found to be higher in babies of Asian women than in those of women from other ethnic groups, while there is some evidence suggesting that ethnic minorities, especially Asian women, are less likely to undergo antenatal screening and prenatal diagnosis, the reasons for which are unclear. This study aims to identify and describe the literature on issues around antenatal screening and prenatal diagnostic testing for genetic disorders among women of Asian descent in western countries. The Medline, CINAHL, ASSIA and PsycInfo databases were searched for the period of 1995 and 2010. Twenty-one studies met the inclusion criteria and were therefore reviewed. In general, Asian women were found to hold favourable attitudes towards testing. However, they reported a poorer understanding of testing than white women and not being offered a test, and were less able to make informed choices. Asian women in the UK and Australia were found to be less likely than their white counterparts to have undergone prenatal diagnosis, while such differences were not found in the USA and Canada. The equity of access to quality antenatal care, alongside comprehensive well thought out antenatal screening programmes, can be assured if strategies are in place which actively involve all ethnic groups and take account of social and cultural appropriateness for the population served. An understanding of broad factors that inform women's decision-making on test uptake would help health professionals provide women and their families with more culturally sensitive information and support that they may additionally need to make more informed choices.

Study protocol of a Dutch smoking cessation e-health program

BACKGROUND

The study aims to test the differential effects of a web-based text and a web-based video-driven computer-tailored approach for lower socio-economic status (LSES) and higher socio-economic status (HSES) smokers which incorporate multiple computer-tailored feedback moments. The two programs differ only in the mode of delivery (video- versus text-based messages). The paper aims to describe the development and design of the two computer-tailored programs.

METHODS/DESIGN

Respondents who smoked at the time of the study inclusion, who were motivated to quit within the following six months and who were aged 18 or older were included in the program. The study is a randomized control trial with a 2 (video/text) * 2(LSES/HSES) design. Respondents were assigned either to one of the intervention groups (text versus video tailored feedback) or to the control group (non-tailored generic advice). In all three conditions participants were asked to fill in the baseline questionnaire based on the I-Change model. The questionnaire assessed socio-demographics, attitude towards smoking, knowledge, self-efficacy, social influence, depression, level of addiction, action planning, goal actions, intention to quit smoking, seven-day point prevalence and continued abstinence. Follow-up measurements were conducted at six and twelve months after baseline.

DISCUSSION

The present paper describes the development of the two computer-tailored smoking cessation programs, their components and the design of the study. The study results reveal different working mechanisms of multiple tailored smoking cessation interventions and will help us to gain more insight into effective strategies to target different subgroups, especially smokers with a lower socio-economic status.

First-trimester Down syndrome screening: pregnant women's knowledge

OBJECTIVES

The primary aim of this study was to assess pregnant women's knowledge of first-trimester combined Down syndrome screening in a setting of required informed consent. As the secondary aim, we wanted to identify relevant differences in knowledge level among subgroups of pregnant women, including those informed in different ways about prenatal examinations.

METHODS

Data stem from a population-based cross-sectional questionnaire study including 15 multiple-choice questions assessing knowledge of different aspects of screening. Included were 6427 first-trimester pregnant women from three Danish obstetric departments offering prenatal screening free of charge. Both participants and non-participants in the screening program were included. The results are based on 4095 responders (64%). Differences between subgroups were examined using chi-squared tests and logistic regression analysis. Estimates are stated with 95% CI.

RESULTS

The majority of the participants (87.6 (86.6-88.6)% to 92.6 (91.7-93.3)%) correctly identified the test concept and the main condition being screened for. Fewer participants (16.4 (15.3-17.6)% to 43.3 (41.8-44.8)%) correctly recognized test accuracy and the potential risk of adverse findings other than Down syndrome. Knowledge level was positively associated with length of education (adjusted ORs 1.0 (0.8-1.4) to 3.9 (2.4-6.4)) and participation in the screening program (adjusted OR 0.9 (0.6-1.3) to 5.9 (3.9-8.8)). Participation in an individual information session was weakly associated with more knowledge.

CONCLUSION

The majority of the pregnant women correctly identified the test concept and the main condition being screened for. The pregnant women were found less knowledgeable on test accuracy and drawbacks.

Knowledge of prenatal screening and psychological management of test decisions

OBJECTIVES

To study associations between pregnant women's knowledge of prenatal screening and decisional conflict in deciding whether to participate in first-trimester screening for Down syndrome in a setting of required informed consent, and to study associations between knowledge and personal wellbeing, and worries in pregnancy.

METHODS

A population-based cross-sectional study with 6427 pregnant women consecutively included before the time of a nuchal translucency scan. Participants were recruited from three Danish obstetric departments offering prenatal screening free of charge. The results presented are based on 4111 pregnant women (64%). Knowledge was measured using 15 questions. The primary outcomes were measured using pre-existing validated scales, i.e. The Decisional Conflict Scale, the WHO Well-Being Index and the Cambridge Worry Scale. Associations were analyzed by multivariate logistic and linear regression analyses.

RESULTS

A higher level of knowledge was associated with less decisional conflict when deciding whether to participate in first-trimester Down syndrome screening (adjusted odds ratio 1.31 (95% CI, 1.26-1.37)). An increased level of knowledge was also associated with higher levels of wellbeing (adjusted linear coefficient 0.51 (95% CI, 0.26-0.75), P < 0.001). Knowledge was not associated with worries, either in general or specifically about something being wrong with the baby.

CONCLUSION

The results of this study indicate the importance of ensuring a high level of knowledge for pregnant women making choices about participation in prenatal screening for Down syndrome in order to improve the psychological management of test decisions.

Ethnic differences in participation in prenatal screening for Down syndrome: a register-based study

OBJECTIVE

To assess ethnic differences in participation in prenatal screening for Down syndrome in the Netherlands.

METHODS

Participation in prenatal screening was assessed for the period 1 January 2009 to 1 July 2009 in a defined postal code area in the southwest of the Netherlands. Data on ethnic origin, socio-economic background and age of participants in prenatal screening were obtained from the Medical Diagnostic Centre and the Department of Clinical Genetics. Population data were obtained from Statistics Netherlands. Logistic regression models were used to assess ethnic differences in participation, adjusted for socio-economic and age differences.

RESULTS

The overall participation in prenatal screening was 3865 out of 15 093 (26%). Participation was 28% among Dutch women, 15% among those from Turkish ethnic origin, 8% among those from North-African origin, 15% among those from Aruban/Antillean origin and 26% among women from Surinamese origin.

CONCLUSIONS

Compared to Dutch women, those from Turkish, North-African, Aruban/Antillean and other non-Western ethnic origin were less likely to participate in screening. It was unexpected that women from Surinamese origin equally participated. It should be further investigated to what extent participation and non-participation in these various ethnic groups was based on informed decision-making.

The role of numeracy on client knowledge in BRCA genetic counseling

OBJECTIVE

To assess the impact of numeracy and health literacy on client's ability to learn information orally communicated during a BRCA 1/2 genetic counseling session.

METHODS

Fifty-nine videotaped simulated genetic counseling sessions were shown to 246 analogue clients (AC) recruited to imagine themselves as the client in the genetic counseling session. AC numeracy, genetic literacy, state and trait anxiety, and decisional conflict were assessed. The primary outcome was AC learning about BRCA 1/2.

RESULTS

Health literacy and numeracy were moderately correlated, and each independently predicted learning. Higher numeracy was associated with higher knowledge scores only among ACs with adequate literacy. Decisional conflict was not related to literacy, numeracy, or knowledge acquisition. It was, however, inversely related to state anxiety so that the higher post-session state anxiety, the lower the AC's decisional conflict.

CONCLUSION

Numeracy and health literacy are associated with learning of orally communicated information during genetic counseling. It appears that numeracy can facilitate learning for literate subjects; it does not, however, make any difference in learning ability of clients with significant literacy deficits.

PRACTICE IMPLICATIONS

Numeracy plays an important role in client's ability to learn information communicated during medical sessions, especially among clients who are otherwise regarded as literate.

Information about prenatal screening for Down syndrome: ethnic differences in knowledge

OBJECTIVE

To evaluate the provision of information about prenatal screening for Down syndrome to women of Dutch, Turkish and Surinamese origins, and to examine the effects of this provision on ethnic differences in knowledge about Down syndrome and prenatal screening.

METHODS

The study population consisted of 105 Dutch, 100 Turkish and 65 Surinamese pregnant women attending midwifery or obstetrical practices in The Netherlands. Each woman was personally interviewed for 3 weeks (mean) after booking for prenatal care.

RESULTS

Most women reported to have received oral and/or written information about prenatal screening by their midwife or obstetrician at booking for prenatal care. Turkish and Surinamese women less often read the information than Dutch women, more often reported difficulties in understanding the information, and had less knowledge about Down syndrome, prenatal screening and amniocentesis. Language skills and educational level contributed most to the explanation of these ethnic variations.

CONCLUSION

Although most Dutch, Turkish and Surinamese women reported to have received information from their midwife or obstetrician, ethnic differences in knowledge about Down syndrome and prenatal screening are substantial.

PRACTICE IMPLICATIONS

Interventions to improve the provision of information to women from ethnic minority groups should especially be aimed at overcoming language barriers, and targeting information to the women's abilities to comprehend the information about prenatal screening for Down syndrome.

Perceptions of prenatal testing for birth defects among rural Latinas

Objectives To examine rural Latinas' understandings of prenatal testing, birth defects, and risk in the context of their expanded AFP (XAFP) screening decisions. Design We conducted a qualitative study using data from in-depth interviews with 33 Latina women receiving prenatal care at three clinic sites in rural areas of California. We analyzed qualitative data by identifying themes that emerged during iterative transcript readings. Quantitative data was used to generate descriptive summary statistics. Results The majority of the participants had not completed high school and had low levels of acculturation. Women in our study tended to view XAFP screening as a routine component of prenatal care that was important for the "health of the baby." Reasons for accepting the XAFP test included reassurance, emotional preparation, and desire for information. Misconceptions included a belief that a normal screening result provides a guarantee of the fetus's health. Generally, participants indicated that, regardless of the screening results, they would not undergo amniocentesis because of the potential miscarriage risk nor would they terminate a pregnancy if their fetus was found to have a chromosome problem. Numerous specific beliefs that differ substantially from medical models regarding birth defects were articulated. Conclusions XAFP screening decisions among rural Latinas are sometimes based on misconceptions of the meaning of test results and the risks associated with undergoing or foregoing testing, and therefore are frequently incongruent with personal testing philosophies and values. Educational efforts and counseling should include clear communication regarding the goals of prenatal screening programs to help these women make informed testing decisions that are reflective of their values and preferences.

Awareness and attitudes regarding prenatal testing among Texas women of childbearing age

Despite increased visibility and availability of prenatal testing procedures, very little is known about the attitudes among the populace toward these procedures. Using a computer assisted telephone interview of pregnant and non-pregnant women of childbearing age we analyze awareness and attitudes regarding prenatal tests among a diverse group of women of childbearing age in Texas. We also examine maternal characteristics associated with awareness and the willingness to undergo these procedures. While 89% were aware that such tests are available, younger, black and less educated women were less likely to know about prenatal tests for birth defects. Seventy-two percent of respondents said they would want their baby tested while Hispanic and black women were significantly more likely to express an interest than non-Hispanic whites. This study demonstrates the variability of knowledge and beliefs and confirms the importance of taking time to understand an individual's personal beliefs, knowledge and attitudes about prenatal diagnosis.

Do pregnant women in Greece make informed choices about antenatal screening for Down's syndrome? A questionnaire survey

OBJECTIVE

to investigate the knowledge and attitudes towards Down's syndrome screening among pregnant women presenting for prenatal screening in Greece, in order to explore whether Greek women are able to make informed choices.

DESIGN

survey using self-administered questionnaires.

SETTING

public hospital in Athens, Greece.

PARTICIPANTS

135 pregnant women with a gestational age of between 11 and 20 weeks, just before antenatal screening for Down's syndrome.

FINDINGS

a total of 96% of women had a positive attitude towards screening and 45% had a good level of knowledge concerning the screening process for Down's syndrome. A standard measure of informed choice was used, which was validated for use in Greek. We found that 44% of women made an informed choice and 56% of women made an uninformed choice. This was because of the low percentage of women with a good level of knowledge. It was also found that knowledge and attitudes were not associated and seemed to be independent of each other. A higher level of informed choice was associated with a higher level of educational achievement and income, time of decision-making and the satisfaction with the decision.

CONCLUSIONS

health professionals should ensure that all women receive appropriate and intelligible information about antenatal screening for Down's syndrome. This information should be suited to women's learning ability in order to increase their knowledge before undergoing screening. Health professionals should educate and increase women's knowledge, and also give women a chance to explore their attitudes and discuss the issues involved.

IMPLICATIONS FOR PRACTICE

on the basis of the current measure of informed choice, we found that knowledge is a weak determinant of uptake of screening. However, the measure focuses on knowledge regarding the screening process, rather than on the condition itself. In addition, informed choice is a far broader concept than the issues covered by the measurement tool. Therefore, it could be concluded that attempts to increase attitude-behaviour consistency (i.e. to increase uptake for women with positive attitudes towards screening and to decrease uptake for women with negative attitudes) could be more successful in increasing informed choice in screening for Down's syndrome in Greece.

Ethnic differences in determinants of participation and non-participation in prenatal screening for Down syndrome: A theoretical framework

OBJECTIVE

To develop a theoretical framework for analysing ethnic differences in determinants of participation and non-participation in prenatal screening for Down syndrome.

METHODS

We applied Weinstein's Precaution Adoption Process (PAP) Model to the decision of whether or not to participate in prenatal screening for Down syndrome. The prenatal screening stage model was specified by reviewing the empirical literature and by data from seven focus group interviews with Dutch, Turkish and Surinamese pregnant women in the Netherlands.

RESULTS

We identified 11 empirical studies on ethnic differences in determinants of participation and non-participation in prenatal screening for Down syndrome. The focus group interviews showed that almost all stages and determinants in the stage model were relevant in women's decision-making process. However, there were ethnic variations in the relevance of determinants, such as beliefs about personal consequences of having a child with Down syndrome or cultural and religious norms.

DISCUSSION

The prenatal screening stage model can be applied as a framework to describe the decision-making process of pregnant women from different ethnic backgrounds. It provides scope for developing culturally sensitive, tailored methods to guide pregnant women towards informed decision-making on participation or non-participation in prenatal screening for Down syndrome.

What role for public health in genetics and vice versa?

Some epidemiologists and geneticists claim that integrating genetics into public health policies and programs is necessary and unavoidable.

OBJECTIVE

To examine the extent to which further integration of public health and genetics is warranted.

METHODS

Synthesis of the literature in four areas: research, genetic services, regulation, and education. The analysis is limited to human genetics.

RESULTS

Public support for basic genetic research has and will continue to lead to new applications and to further understanding of human origins and dispersions. Some applied research, particularly for genetic risk factors for common complex diseases, has low yield and is better supported by private funds. The only genetic service for which a public health role is paramount is newborn screening. With the patenting of genes, and the proliferation of commercial interests in genetic tests and directly advertising them to the public, regulation by public health agencies is increasingly important. As most genetic testing and other services will be provided in the personal health care system, education about genetics is best left to the educational and medical systems. Public health practitioners should be aware of the limitations of genetic tests.

CONCLUSIONS

There is little need for further integration of genetic services and education into public health especially in countries in which public and private health services are dichotomized. Newborn screening and follow-up, however, are most safely and effectively provided under public health auspices. The most important area for strengthening the public health role is in the regulation of genetic tests and other genetic services provided primarily by the private sector. Continued support for basic genetic research is needed.

Postpartum depression and social support in adolescents

OBJECTIVE

The purpose of the study was to determine the effectiveness of a social support intervention delivered to pregnant adolescent girls between 32 and 36 weeks of gestation in preventing symptoms of depression at 6 weeks postpartum.

DESIGN

The study used a repeated measures design.

SETTING

Data were collected at a teenage parenting program, an educational option of the public school system.

PARTICIPANTS

Participants (n = 128) were pregnant and postpartum adolescents.

MAIN OUTCOME MEASURE

Symptoms of depression at 6 weeks postpartum.

INTERVENTION

Participants completed the Postpartum Support Questionnaire, Rosenberg's Self-Esteem instrument, and the Center for Epidemiological Studies of Depression instrument at baseline, then were randomly assigned to one of three intervention groups (pamphlet, video, or pamphlet plus video) or the control group. The content of the intervention was based on a synthesis of the literature describing social support needed and desired by postpartum adolescents.

RESULTS

No significant differences were found in Center for Epidemiological Studies of Depression instrument scores among the groups at 6 weeks postpartum. Using path analysis, the authors found that predictors of symptoms of depression at 6 weeks postpartum were (a) receiving more support from friends, family, and others and (b) having low self-esteem.

CONCLUSION

These findings differ from earlier studies, and both research and clinical implications are discussed.

Translating evidence-based information into effective risk communication: Current challenges and opportunities

Recent medical advances and the easy availability of evidence-based information at the point of care are believed to provide physicians with improved tools for risk communication. However, evidence indicates that physicians still display marked variability in ordering tests. Factors that determine a physician's test-ordering tendencies vary by specialization, practice, geographical location, defensive practice, and tolerance of uncertainty and are also modified by patient requests. Understanding of statistical terms on the part of both physicians and patients remains limited. Physicians may display limited ability to assess pretest and posttest probabilities, especially in low- and intermediate-risk patients, even after attending short courses in epidemiology, or may find the process impractical. Presentation of diagnostic-test results in a natural-frequency format might improve understanding. Both physicians and patients have difficulty grasping the term "number needed to treat" compared with "relative risk reduction" when comparing therapeutic options. Other patient-related factors that limit understanding include low literacy, individual risk tolerance, and framing patterns of the problem (potential gains vs losses). Despite numerous available modalities (quantitative and qualitative) of risk communication, consensus over the advantage of any single modality in translating evidence into risk communication is limited. It is essential that physicians remain patient-centered, generate trust, and build a partnership with the patient to achieve consensus for medical decision-making. Future studies are indicated to assess the effectiveness of novel risk-communication modalities based on patients' and physicians' characteristics and identify appropriate modality of translating evidence (quantitative or qualitative information).

People who influence women's decisions and preferred sources of information about prenatal testing for birth defects

BACKGROUND

More than half of Victorian pregnant women are undergoing prenatal testing for birth defects, although little is known about the factors that are influencing their decisions.

AIMS

To examine whom women perceived as influencing their decision about prenatal testing for birth defects, with whom they would have liked to talk more, and what sources of information they preferred.

METHODS

A total of 737 pregnant women aged 37 years and over, who either had or had not undergone prenatal testing (screening and/or diagnosis) completed a questionnaire in 18 hospitals throughout Victoria.

RESULTS

Over 90% reported that they themselves had a strong influence on their decision, and 70% reported their partner as strongly influencing their decision. Approximately 30% of women who had both screening and diagnosis and more than 20% of women who had no prenatal testing, would like to have discussed prenatal testing with women who had previously had testing. Face-to-face counselling with a doctor or counsellor was the preferred source of information, followed by a pamphlet as the second choice.

CONCLUSIONS

Given that both tested and untested women felt so strongly that they were responsible for their own decisions about prenatal testing, it is unlikely that universal acceptance and uptake will occur, even in this group of women of advanced maternal age. A support network of women who have already had testing could supplement existing sources of support. However, there continues to be a need for face-to-face sessions with a doctor or counsellor in combination with printed material.

Taking antenatal group B Streptococcus seriously: women's experiences of screening and perceptions of risk

BACKGROUND

Early-onset group B streptococcal disease is a serious cause of neonatal morbidity and mortality. Although screening protocols for group B streptococcus are common, little is known of women's perceptions of this screening and the disease itself. The purpose of this study was to gain an understanding of women's experiences, knowledge, and perceptions about this bacteria and its screening.

METHODS

Nine focus group interviews with 35 women explored their experiences and understanding of group B streptococcus screening. Transcribed interview data were interpreted to identify and articulate the women's experiences.

RESULTS

Most women had little knowledge or understanding of group B streptococcus, obtaining their information largely from the stories or experiences of friends or family. Women struggled to understand the meaning and implications, both physical and "moral," of the disease for their baby and for themselves, clearly indicating both the subjective and statistical importance of the concept of risk for pregnant women.

CONCLUSIONS

Group B streptococcus continues to be poorly understood by pregnant women who try to understand and weigh up its risks and implications so as to make the best decisions about screening. The women participated in screening ultimately, however, since it was seen to be patently "best for baby," relatively easy for them to undergo, and part of routine antenatal care.

A prenatal intervention study to improve timeliness of immunization initiation in Latino infants

This was a prospective randomized cohort study to assess the effectiveness of an educational immunization intervention with pregnant Latinas on timely initiation of infant immunization. Study participants were recruited from two community clinics in north San Diego County. A total of three hundred and fifty-two Latinas in the third trimester of pregnancy were recruited and randomly assigned to intervention or control groups. Participants received either a culturally and linguistically appropriate session on infant immunization (intervention) or a session on prevention of Sudden Infant Death Syndrome (control). The main outcome measures were pre-post immunization knowledge change and infant immunization status at 92 days. Immunization knowledge increased significantly in the intervention group [p < .0001, 95%CI (1.76, 2.47)]. No difference was found between groups in immunization series initiation: 95 percent of the children in the intervention group were up-to-date by 92 days from birth, and 93 percent of the control group was up-to-date at 92 days. The lack of significant association between receiving immunization education and infant immunization series initiation suggests that parent education may be necessary but not sufficient for timely immunization, particularly in clinics with effective well-child programs. Given the significant increase in immunization knowledge, the broader and perhaps more important implication is that language- and culturally specific infant health education messages in the prenatal period may have a positive long-term impact on the child's health and promote well-child care overall. Future studies should assess the role of prenatal well-child education in the context of clinics with low immunization levels.

Prospective assessment in newborns of diabetes autoimmunity (PANDA): maternal understanding of infant diabetes risk

PURPOSE

To assess accuracy of mothers' understanding of their newborns' genetic risk for type 1 diabetes and to identify predictors of the comprehension and retention of genetic information.

METHODS

Mothers of 435 newborns genetically screened at birth were informed of the infant's risk for type 1 diabetes using a standard script that provided both categorical and numerical risk information. The mothers' comprehension and retention of this information were assessed by structured interview on two occasions, approximately 3.6 weeks and approximately 3.9 months postnotification.

RESULTS

At the initial interview, 73.1% of mothers gave a correct estimate of their child's genetic risk, 3.2% overestimated risk, 13.3% underestimated risk, and 10.3% could not recall risk at all. At the follow-up interview, fewer mothers (61.9%) correctly estimated their child's risk and more mothers (24.4%) underestimated their child's risk. Maternal accuracy was associated with maternal education, ethnic minority status, infant risk status, maternal ability to spontaneously recall both categorical and numerical risk estimates, and length of time since risk notification. Underestimation of risk was associated with maternal education, family history of diabetes, time since risk notification, and maternal anxiety about the baby's risk.

CONCLUSION

The accuracy of mothers' recall of infant risk declines over time, with an increasing number of mothers underestimating the infant's risk. Effective risk communication strategies need to be developed and incorporated into genetic screening programs.

Levels of knowledge of Down syndrome and Down syndrome testing in Australian women

At their first hospital antenatal visit, 209 women were interviewed to explore their level of knowledge of Down syndrome and the available prenatal tests. Overall, the women had limited knowledge. Non-Caucasian women had less knowledge of Down syndrome, available prenatal tests and the association of Down syndrome with advanced maternal age than Caucasian women. Women with a history of a previous pregnancy and women over 35 years of age were not more aware of Down syndrome or the available tests than other women. These findings have significant implications for antenatal education and the implementation of screening programs for Down syndrome.

Midwife or doctor: a study of pregnant women making delivery decisions

Eighty-eight women from diverse educational backgrounds were interviewed as they made several important and related life decisions during their pregnancies. In this article, the focus is on the choice of birth attendant. There were few differences between those women who did and did not consider a midwife. Women who selected a midwife reported feeling more knowledgeable about birth attendants, more in control over the birth attendant decision, more satisfied about their delivery decisions, more in control of and satisfied with pain medication decisions, more autonomous in their pregnancy decision making, and more in agreement with "alternative birth" philosophies. and less in agreement with "conventional birth" philosophies. The participants also reported receiving more approval from spouse/significant other and friends, were more likely to use "gut instinct" and previous experience or habit to make pregnancy decisions, and were more ready to make these decisions than were women who had not selected a midwife as their primary birth attendant.

The risks of multimedia methods: effects of actor's race and gender on preferences for health states

OBJECTIVE

While the use of multimedia methods in medical education and decision support can facilitate learning, it also has certain hazards. One potential hazard is the inadvertent triggering of racial and gender bias by the appearance of actors or patients in presentations. The authors hypothesized that race and gender affect preferences. To explore this issue they studied the effects of actors' race and gender on preference ratings for health states that include symptoms of schizophrenia.

DESIGN

A convenience sample of patients with schizophrenia, family members of patients, and health professionals was used. Participants were randomly assigned to rate two health states, one portrayed by either a man of mixed race (Hispanic-black) or a white man and the second portrayed by either a white woman or a white man.

MEASUREMENTS

Visual analog scale (VAS) and standard gamble ratings of health state preferences for health states that include symptoms of mild and moderate schizophrenia.

RESULTS

Studies of the effects of the race of the actor (n = 114) revealed that racial mismatch between the actor and the participant affected the participant's preferences for health states. Ratings were lower when racial groups differed (mean difference, 0.098 for visual analog scale ratings and 0.053 lower in standard gamble, P = 0.006 for interactions between the race of the subject and the actor). In studies of the effects of a female actress on ratings (n = 117), we found no evidence of a corresponding interaction between the gender of the actor and the study participant. Rather, an interaction between actor's gender and method of assessment was observed. Standard gamble ratings (difference between means, 0.151), but not visual analog scale ratings (difference, 0.005), were markedly higher when the state was portrayed by the actress (P = 0.003 for interactions between actor's gender and method of preference assessment). Differential effects on standard gamble ratings suggest that an actor's gender may influence the willingness of viewers to gamble to gain health benefits (or risk attitude).

CONCLUSIONS

Educators and researchers considering the use of multimedia methods for decision support need to be aware of the potential for the race and gender of patients or actors to influence preferences for health states and thus, potentially, medical decisions.

Videotape increases parent knowledge about poliovirus vaccines and choices of polio vaccination schedules

OBJECTIVE

To study the effect of an educational videotape about poliovirus vaccines and choices of schedules for parents/guardians of children starting the polio vaccination series.

DESIGN

Prospective, randomized trial comparing two educational interventions.

SETTING

Five pediatric offices (two university-based, two health maintenance organization staff models, and one private practice) and a local health department immunization clinic in the greater Lansing, MI, area.

PARTICIPANTS

A total of 287 parents/guardians of 2- to 3-month-olds presenting for well-child care and due for the first set of immunizations including poliovirus vaccine.

INTERVENTIONS

Parents/guardians were randomized to read the vaccine information statement (VIS) alone or to read the VIS and view a 15-minute videotape about polio vaccination and choices of schedules produced by Michigan State University. The intervention groups were similar by race/ethnicity, education, and relationship to the child.

OUTCOME MEASURES

Change in knowledge about the risk of poliomyelitis in the United States, transmission of poliomyelitis, characteristics of the two poliovirus vaccines, and choices of polio vaccination schedules; and parent opinion on effectiveness of the interventions, as measured by pre- and postintervention questionnaires.

RESULTS

Both interventions resulted in increased test scores of knowledge. However, videotape viewers scored significantly higher on their posttest compared with parents/guardians assigned to VIS only. This significant increase was noted across all practice types, two of three major racial/ethnic groups, and educational levels. (The increase for Hispanic parents/guardians approached significance). Reading the VIS did not improve posttest scores for videotape viewers. Reading the VIS did improve posttest scores for those assigned to VIS only, but these scores still were not as high as for videotape viewers who did not read the VIS.

CONCLUSIONS

This study demonstrated that a complicated discussion of risks/benefits of two vaccines and their schedules of administration could be communicated effectively via a videotaped presentation. In addition, the videotape was more effective than VIS alone in increasing short-term knowledge, regardless of practice type, race/ethnicity, or educational level. As immunization schedules increase in complexity and parents are asked to make more choices, videotaped information may be a better method to achieve the goal of truly informed consent.

Prenatal screening and women's perception of infant disability: a Sophie's Choice for every mother

Prenatal screening can significantly benefit parents and the community. However, it has created a dilemma for women as it requires them to quickly decide whether to continue a pregnancy or terminate it should the test indicate a foetal abnormality. This can be psychologically traumatic for women torn between their connection to an unborn child with all its possible imperfections, and a desire to prevent its suffering as a disabled child in later life. A woman must also consider her own and her family's future welfare. Extensive research into the physical aspects of prenatal screening has not explored the meaning of the experience for women or whether termination is the most appropriate option. This article examines recent qualitative studies, concluding that women who terminate a pregnancy following prenatal screening may experience an acute grief reaction or be plagued by guilt and fear that can precipitate marital breakdown. Additionally, there is a risk that through striving to eradicate congenital disability, a community risks promoting a cult of perfectionism that may have discriminatory effects on disabled people.

Informed consent for maternal serum alpha-fetoprotein screening in an inner city population: how informed is it?

OBJECTIVE

To determine if women who received information from a provider and viewed a videotape about maternal serum alpha-fetoprotein (MSAFP) screening understood enough to sign informed consent.

DESIGN

A prospective qualitative design using tape recorded interviews of women who were provided information regarding MSAFP testing from a provider and from viewing a videotape.

PARTICIPANTS

Fifty-three inner city pregnant women (58% Hispanic, 39% African-American, 3% white).

RESULTS

Two women answered all questions correctly; no one answered all questions incorrectly. Sixty-two percent correctly answered "What is MSAFP?" Sixteen percent thought "something has to be taken from my belly" for the test. Fifty-nine percent understood that children with spina bifida could have difficulty walking or urinary problems. Seventy-two percent thought their infant would be healthy in all respects if the test was negative. Only 45% could describe the follow-up to a positive test. Eighty percent planned to have the test. Many misconceptions were apparent, and for some knowledge items, as many as 80% of the women answered incorrectly.

CONCLUSIONS

Obtaining truly informed consent for a complex test is not a simple process. Participants met a few, but not all, of the criteria for informed consent. Women understood that the test was voluntary, but their comprehension of the meaning and implication of a positive test results was deficient. Despite this, they signed the informed consent document. The larger question of just how much comprehension is required to consider a woman "informed" has not been answered.
