Behaviour change techniques and contraceptive use in low and middle income countries: a review

Increasing coverage and uptake of voluntary family planning in Uganda's emerging municipalities and secondary cities: An implementation research study protocol

INTRODUCTION

While urban areas are often perceived to have better access to healthcare services, including modern family planning (FP) services, urban dwellers including those with better socioeconomic status are faced with multidimensional challenges that shape their access to appropriate FP services. In Uganda's urban spaces, there is currently a lack of understanding among service providers, civil society organizations, and individuals/communities regarding the implementation of interventions that promote informed choice and voluntary use of family planning services. This knowledge gap has profound implications for reproductive rights. This study seeks to enhance existing efforts towards increasing coverage and uptake of Voluntary Family Planning (VFP) in Jinja City and Iganga Municipality, central eastern Uganda. Our primary question is, "What interventions can effectively be packaged and delivered to increase the uptake of VFP among different segments of urban residents?"

METHODS

We propose to use the Human-Centered Design (HCD) approach to understand the needs and challenges of users and community capabilities in ensuring access to VFP services. Co-creating with stakeholders' engagement and a data-driven-centric approach will steer design and adaptation that respond to the different population segments within the urban space. As such, the study will be implemented in three phases: formative assessment, design and implementation, and implementation monitoring and evaluation. The implementation process will incorporate robust monitoring, learning, and adaptation mechanisms. The primary focus of these mechanisms will be to utilize gathered information effectively to inform the design of the implementation and facilitate continuous learning throughout the process. The study will apply a process monitoring and evaluation approach to address questions related to what package of FP interventions work, for whom, under what circumstances and why.

DISCUSSION

Guided by strong learning and implementation flexibility, we hypothesize that our implementation will provide segmentation-specific high-impact interventions in an urban context.

Evaluating the Effectiveness of Educational Interventions in Family Planning for Men in Developing Countries: A Systematic Review

Introduction

Unintended pregnancy is associated with national socioeconomic development and gender inequality. In addition to contraception, educational interventions that promote family planning and address gender dynamics are considered important in preventing unintended pregnancy. While the importance of encouraging men's participation in family planning has been advocated, most studies have focused on the application of interventions to women or populations in high-income countries only. Therefore, we conducted a systematic review to evaluate the effects of educational interventions on men in low- and middle-income countries in terms of knowledge, attitudes, practices, and gender dynamics.

Methods

Three electronic databases (CINAHL, Ovid MEDLINE, and Web of Science) were searched for studies published from January 1980 to October 2022. Keywords such as "men/husband," "family planning," "contraception," and "education" were combined to identify studies. Two independent reviewers conducted screening and data extraction, and the risk of bias was assessed using the Risk of Bias 2 tool. The quality of evidence was evaluated according to the GRADE Handbook.

Results

The database search identified 16,086 articles, of which 4 cluster randomized controlled trials (RCTs) and 1 RCT were ultimately included. Each of them was conducted in four different countries: Malawi, Guatemala, Tanzania, and India. Changes in knowledge, attitude, family planning, and gender dynamics were the outcomes used to assess the effectiveness of interventions. The five selected articles exhibited an effect on ≥1 indicator for each outcome. However, the quality of evidence was determined to be low or very low owing to the risk of bias, heterogeneity, and imprecision.

Conclusions

Determining the effectiveness of educational interventions in family planning for men in low- and middle-income countries requires additional high-quality intervention studies. As family planning is influenced by various background factors, it is important to develop appropriate interventions for each context and define relevant indicators that can be compared across contexts.

Involving men and boys in family planning: A systematic review of the effective components and characteristics of complex interventions in low- and middle-income countries

Background

Involving men and boys as both users and supporters of Family Planning (FP) is now considered essential for optimising maternal and child health outcomes. Evidence on how to engage men and boys to meet FP needs is therefore important.

Objectives

The main objective of this review was to assess the strength of evidence in the area and uncover the effective components and critical process- and system-level characteristics of successful interventions.

Search Methods

We searched nine electronic databases, seven grey literature databases, organisational websites, and the reference lists of systematic reviews relating to FP. To identify process evaluations and qualitative papers associated with the included experimental studies, we used Connected Papers and hand searches of reference lists.

Selection Criteria

Experimental and quasi-experimental studies of behavioural and service-level interventions involving males aged 10 years or over in low- and middle-income countries to increase uptake of FP methods were included in this review.

Data Collection and Analysis

Methodology was a causal chain analysis involving the development and testing of a logic model of intervention components based on stakeholder consultation and prior research. Qualitative and quantitative data relating to the evaluation studies and interventions were extracted based on the principles of 'effectiveness-plus' reviews. Quantitative analysis was undertaken using r with robust variance estimation (RVE), meta-analysis and meta-regression. Qualitative analysis involved 'best fit' framework synthesis.

Results

We identified 8885 potentially relevant records and included 127 in the review. Fifty-nine (46%) of these were randomised trials, the remainder were quasi-experimental studies with a comparison group. Fifty-four percent of the included studies were assessed as having a high risk of bias. A meta-analysis of 72 studies (k = 265) showed that the included group of interventions had statistically significantly higher odds of improving contraceptive use when compared to comparison groups (odds ratio = 1.38, confidence interval = 1.21 to 1.57, prediction interval = 0.36 to 5.31, p < 0.0001), but there were substantial variations in the effect sizes of the studies (Q = 40,647, df = 264, p < 0.0001; I 2 = 98%) and 73% was within cluster/study. Multi-variate meta-regression revealed several significant intervention delivery characteristics that moderate contraceptive use. These included community-based educational FP interventions, interventions delivered to women as well as men and interventions delivered by trained facilitators, professionals, or peers in community, home and community, or school settings. None of the eight identified intervention components or 33 combinations of components were significant moderators of effects on contraceptive use. Qualitative analysis highlighted some of the barriers and facilitators of effective models of FP that should be considered in future practice and research.

Authors' Conclusions

FP interventions that involve men and boys alongside women and girls are effective in improving uptake and use of contraceptives. The evidence suggests that policy should continue to promote the involvement of men and boys in FP in ways that also promote gender equality. Recommendations for research include the need for evaluations during conflict and disease outbreaks, and evaluation of gender transformative interventions which engage men and boys as contraceptive users and supporters in helping to achieve desired family size, fertility promotion, safe conception, as well as promoting equitable family planning decision-making for women and girls.

Exploring the effects of COVID-19 on family planning: results from a qualitative study in rural Uganda following COVID-19 lockdown

BACKGROUND

The COVID-19 pandemic has likely affected the already high unmet need for family planning in low- and middle-income countries. This qualitative study used Andersen's Behavioral Model of Health Service Use as a theoretical framework to explore the possible ways in which the COVID-19 pandemic, including the impact of a 3-month government mandated lockdown, might affect family planning outcomes in rural Uganda. A secondary aim was to elicit recommendations to improve family planning service delivery in the context of COVID-19.

METHODS

Between June and October 2020, we conducted four focus group discussions with men and women separately (N = 26) who had an unmet need for family planning, and 15 key-informant interviews with community leaders and family planning stakeholders. Data were analyzed using thematic analysis.

RESULTS

We identified a significant disruption to the delivery of family planning services due to COVID-19, with potential negative effects on contraceptive use and risk for unintended pregnancy. COVID-19 had a negative effect on individual enabling factors such as family income, affecting service access, and on community enabling factors, such as transportation barriers and the disruption of community-based family planning delivery through village health teams and mobile clinics. Participants felt COVID-19 lockdown restrictions exacerbated existing contextual predisposing factors related to poverty and gender inequity, such as intimate partner violence and power inequities that diminish women's ability to refuse sex with their husband and their autonomy to use contraceptives. Recommendations to improve family planning service delivery in the context of COVID-19 centered on emergency preparedness, strengthening community health systems, and creating new ways to safely deliver contractive methods directly to communities during future COVID-19 lockdowns.

CONCLUSIONS

This study highlights the consequences of COVID-19 lockdown on family planning distribution, as well as the exacerbation of gender inequities that limit women's autonomy in pregnancy prevention measures. To improve family planning service uptake in the context of COVID-19, there is a need to strengthen emergency preparedness and response, utilize community structures for contraceptive delivery, and address the underlying gender inequities that affect care seeking and service utilization.

The "Family Health = Family Wealth" intervention: study protocol for a pilot quasi-experimental controlled trial of a multi-level, community-based family planning intervention for couples in rural Uganda

BACKGROUND

Uganda has one of the highest fertility rates globally, but only 30% of women report using an effective method of contraception. Community-based, multi-level interventions are needed to help couples in rural Uganda overcome barriers to contraceptive use.

METHODS

This study will pilot test the Family Health = Family Wealth intervention, a multi-level, community-based intervention employing transformative community dialogues, which use facilitated discussion to reshape community norms that influence family planning acceptance, to alter individual attitudes and the perception of community norms that discourage family planning. Community dialogues are delivered to groups of couples over 4 sessions (two gender-segregated and two gender-mixed). Sessions simultaneously address individual and interpersonal-level determinants of family planning and link couples to family planning services. At the health system level, a refresher training will be conducted with health workers in the intervention community's health center to address gaps in contraceptive knowledge and skills as identified from a needs assessment. The intervention will be evaluated through a pilot quasi-experimental trial paired with a mixed methods process evaluation. Participants include 70 couples (N=140) randomized by community to the Family Health = Family Wealth intervention (n=35 couples) or to an attention-matched water, sanitation, and hygiene (WASH) intervention (n=35 couples). Participants include sexually active, married couples who are age 18 (or an emancipated minor) to 40 for women and age 18 (or an emancipated minor) to 50 for men, not pregnant, at least one person in the couple reports wanting to avoid pregnancy for at least a year, and not currently using a method of contraception or using a low-efficacy or ineffective method of contraception. The primary aims of the study are to (1) assess the feasibility of the intervention trial procedures, (2) the acceptability and feasibility of the intervention content and structure, and (3) explore the intervention's preliminary effectiveness at increasing contraceptive use and affecting related outcomes among couples.

DISCUSSION

Filling the unmet need for family planning has important public health implications, including reductions in pregnancy-related health risks and deaths, and infant mortality. This pilot intervention trial will gather preliminary evidence on the acceptability, feasibility, and potential effect of a novel, multi-level, community-based intervention to increase contraceptive use among couples with an unmet need for family planning in rural Uganda. We aim to use the findings of this pilot study to refine the trial procedures and intervention content for a future, larger cluster randomized controlled trial to establish the intervention's efficacy.

Using Behavioural Economics to Analyse and Enhance Contraception Usage Decisions

Existent literature helped narrow down variables influencing modern contraceptive adoption (usage), a behaviour carrying enormous positive externality. Using finite population sample size formula and probability proportional to size method of sample selection, primary data was collected from participants using inclusion and exclusion criterions. Binary logistic regression model was used to predict probability of occurrence of dependent variable ‘usage of modern method of contraception’ being treated at a dichotomous outcome level. Predictor variables after confirming association by cross tabulation were introduced stepwise to build model subject to elimination of those variables adding insignificantly to the overall predictability of the model. Variables such as gender, education level, spousal influence, extended family influence, financial well-being and contraceptive information were found to significantly predict the probability of occurrence of the dependent variable. Except for financial well-being with three sub-categories, other independent variables were treated at dichotomous level. Income level was found to be an important predictor although found statistically insignificant. Non-contributory factors such as age, occupation and years of marriage were dropped. Post-model construction, borrowing ‘nudges’ from behavioural economics (BE) domain, strategies to nurture the significant context specific influencing variables, were articulated. BE was particularly preferred for its openness to the paradigm of non-rational behavioural choices.

Which Structural Interventions for Adolescent Contraceptive Use Have Been Evaluated in Low- and Middle-Income Countries?

Reducing adolescent childbearing is a global priority, and enabling contraceptive use is one means of achieving this. Upstream factors, e.g., gender inequalities, fertility norms, poverty, empowerment and schooling, can be major factors affecting contraceptive use. We conducted a systematic map to understand which structural adolescent contraception interventions targeting these upstream factors have been evaluated in LMICs. We searched eight academic databases plus relevant websites and a 2016 evidence gap map and screened references based on set inclusion criteria. We screened 6993 references and included 40 unique intervention evaluations, reported in 138 papers. Seventeen evaluations were reported only in grey literature. Poverty reduction/economic empowerment interventions were the most common structural intervention, followed by interventions to increase schooling (e.g., through legislation or cash transfers) and those aiming to change social norms. Half of the evaluations were RCTs. There was variation in the timing of endline outcome data collection and the outcome measures used. A range of structural interventions have been evaluated for their effect on adolescent contraceptive use/pregnancy. These interventions, and their evaluations, are heterogenous in numerous ways. Improved understandings of how structural interventions work, as well as addressing evaluation challenges, are needed to facilitate progress in enabling adolescent contraceptive use in LMICs.

Nothing so practical as theory: a rapid review of the use of behaviour change theory in family planning interventions involving men and boys

BACKGROUND

There is growing recognition of the need for interventions that effectively involve men and boys to promote family planning behaviours. Evidence suggests that the most effective behavioural interventions in this field are founded on theoretical principles of behaviour change and gender equality. However, there are few evidence syntheses on how theoretical approaches are applied in this context that might guide best practice in intervention development. This review addresses this gap by examining the application and reporting of theories of behaviour change used by family planning interventions involving men and boys.

METHODS

We adopted a systematic rapid review approach, scoping findings of a previously reported evidence and gap map of intervention reviews (covering 2007-2018) and supplementing this with searches of academic databases and grey literature for reviews and additional studies published between 2007 and 2020. Studies were eligible for inclusion if their title, abstract or keywords referred to a psychosocial or behavioural intervention targeting family planning behaviours, involved males in delivery, and detailed their use of an intervention theory of change.

RESULTS

From 941 non-duplicate records identified, 63 were eligible for inclusion. Most records referenced interventions taking place in low- and middle-income countries (65%). There was a range of intervention theories of change reported, typically targeting individual-level behaviours and sometimes comprising several behaviour change theories and strategies. The most commonly identified theories were Social Cognitive Theory, Social Learning Theory, the Theory of Planned Behaviour, and the Information-Motivation-Behaviour Skills (IMB) Model. A minority of records explicitly detailed gender-informed elements within their theory of change.

CONCLUSION

Our findings highlight the range of prevailing theories of change used for family planning interventions involving men and boys, and the considerable variability in their reporting. Programmers and policy makers would be best served by unified reporting and testing of intervention theories of change. There remains a need for consistent reporting of these to better understand how complex interventions that seek to involve men and boys in family planning may lead to behaviour change.

Utilisation of sexual and reproductive health services among street children and young adults in Kampala, Uganda: does migration matter?

BACKGROUND

While the nexus of migration and health outcomes is well acknowledged, the effect of rural-urban migration on the use of sexual and reproductive health (SRH) services has received less attention. We assessed the effect of rural-urban migration on the use of SRH services, while controlling for confounding, and whether there is a difference in the use of SRH services among migrant and non-migrant street children and young adults.

METHODS

Data were collected from 513 street children and young adults aged 12-24 years, using venue-based time-space sampling (VBTS). We performed multivariate logistic regression analysis using Stata 16.0 to identify factors associated with SRH services use, with rural-urban migration status as the main predictor. Participants were further classified as new migrants (≤ 2 years of stay in city), established migrants (> 2 years of stay in city) or non-migrants (lifelong native street children) with no rural-urban migration history.

RESULTS

Overall, 18.13% of the street children and young adults had used contraception/family planning, 58.67% had tested for human immunodeficiency virus (HIV) and knew their status and 34.70% had been screened for sexually transmitted infections (STIs). Non-migrants were 2.70 times more likely to use SRH services (HIV testing, STI screening and family planning) compared to the migrants (aOR = 2.70, 95% CI 1.23-5.97). Other factors associated with SRH services use among street children and young adults include age (aOR = 4.70, 95% CI 2.87-7.68), schooling status (aOR = 0.33, 95% CI 0.15-0.76), knowledge of place of care (aOR = 2.71, 95% CI 1.64-4.46) and access to SRH information (aOR = 3.23, 95% CI 2.00-5.24).

CONCLUSIONS

SRH services utilisation among migrant street children and young adults is low compared to their non-migrant counterparts and is independently associated with migration status, age, schooling status, knowledge of place of care and access to SRH information. Our findings call for the need to design and implement multi-dimensional interventions to increase the use of SRH services among street children and young adults, while taking into consideration their migration patterns.

Effectiveness of mHealth Interventions for Improving Contraceptive Use in Low- and Middle-Income Countries: A Systematic Review

Do mHealth interventions help reduce unmet contraceptive needs in low- and middle-income countries by attempting to increase the uptake of modern contraceptive methods? Which mHealth features and behavior change communication components were used in these mHealth interventions? This review aimed to answer these questions and assess the impact of these interventions on contraceptive uptake outcomes.

Background:

mHealth interventions are being tested to improve contraceptive uptake in low- and middle-income countries (LMICs); however, the effectiveness of these interventions has not been systematically reviewed.

Objectives:

The primary objective of this systematic review was to assess the effectiveness of mHealth interventions to improve contraceptive uptake and adherence in LMICs. A second objective was to identify mHealth features and behavior change communication components used in these mHealth interventions.

Methods:

A systematic search was conducted of online databases for peer-reviewed articles that reported on intervention studies with men and women from LMICs and measured mHealth intervention impact on contraceptive uptake and/or adherence. Key search terms included “mHealth” or “mobile health,” “contraception” or “family planning,” and “low- and middle-income countries.” PRISMA guidelines were followed for reporting review methods and findings. The Cochrane risk-of-bias 2 tool for randomized trials was used to assess the risk of bias of the included studies. The GRADE approach was used to determine the quality of evidence.

Results:

Eight randomized controlled trial studies met the inclusion criteria. Four studies experienced implementation challenges (e.g., intervention components were not utilized fully by participants, intervention participants did not receive the full intervention content, contamination, low response rate, and/or missing data). Only 3 interventions were found to be effective, and these included a “push” approach, interactive communication, information tailored to participants, motivational messaging, and male partner involvement.

Conclusion:

To date, the delivery of mHealth interventions for improving family planning in LMICs has met with implementation challenges that have reduced the researcher’s ability to test intervention effectiveness. Although 3 of 8 studies found improved contraceptive use in the intervention group, the review cannot draw concrete conclusions on the overall effectiveness of mHealth interventions to increase contraceptive use in LMICs. Further research with robust program fidelity is recommended.

Improving a long-acting reversible contraception usage by understanding client perspectives

BACKGROUND Despite the limited use of long-acting reversible contraception (LARC) in Indonesia, they have proven to be cost-effective in family planning programs. This study was aimed to identify the elements of ideas and views that people hold and their association with the use of LARC (intrauterine devices and implants) as a means of improving its utilization in Nusa Tenggara Barat (NTB) Province, Indonesia. METHODS Data were derived from the Improving Contraceptive Mix Methods survey of 6,384 respondents in Bima District, Central Lombok, and North Lombok, NTB Province, in 2015. Confirmatory factor analysis was used to identify suitable elements of 19 variables and generate three ideation elements on attitude, knowledge, and interpersonal communication. Subsequently, the association of three ideation elements with LARC use in NTB was examined. RESULTS Multivariate analysis revealed that LARC use was higher among women with a positive attitude toward LARC and high frequency of interpersonal communication. Women with positive attitudes had 7 times greater odds of using LARC than women with negative attitudes (adjusted odds ratio [aOR] = 7.18; 95% confidence interval [CI] = 6.09–8.55). Women with a high frequency of interpersonal communication were 2.4 times more likely to use LARC than women with low communication frequency (aOR = 2.40; 95% CI = 1.94–2.99). CONCLUSIONS To increase the use of LARC in NTB, family planning programs should not only focus on improving women’s knowledge but also prioritizing the promotion of positive attitudes toward LARC and facilitating interpersonal communication.

Development of an integrated, district-wide approach to pre-pregnancy management for women with pre-existing diabetes in a multi-ethnic population

BACKGROUND

Poor diabetes management prior to conception, results in increased rates of fetal malformations and other adverse pregnancy outcomes. We describe the development of an integrated, pre-pregnancy management strategy to improve pregnancy outcomes among women of reproductive age with diabetes in a multi-ethnic district.

METHODS

The strategy included (i) a narrative literature review of contraception and pre-pregnancy interventions for women with diabetes and development of a draft plan; (ii) a chart review of pregnancy outcomes (e.g. congenital malformations, neonatal hypoglycaemia and caesarean sections) among women with type 1 diabetes (T1D) (n = 53) and type 2 diabetes (T2D) (n = 46) between 2010 and 2015 (iii) interview surveys of women with T1D and T2D (n = 15), and local health care professionals (n = 13); (iv) two focus groups (n = 4) and one-to-one interviews with women with T1D and T2D from an Australian background (n = 5), women with T2D from cultural and linguistically diverse (CALD) (n = 7) and indigenous backgrounds (n = 1) and partners of CALD women (n = 3); and (v) two group meetings, one comprising predominantly primary care, and another comprising district-wide multidisciplinary inter-sectoral professionals, where components of the intervention strategy were finalised using a Delphi approach for development of the final plan.

RESULTS

Our literature review showed that a range of interventions, particularly multifaceted educational programs for women and healthcare professionals, significantly increased contraception uptake, and reduced adverse outcomes of pregnancy (e.g. malformations and stillbirth). Our chart-review showed that local rates of adverse pregnancy outcomes were similarly poor among women with both T1D and T2D (e.g. major congenital malformations [9.1% vs 8.9%] and macrosomia [34.7% vs 24.4%]). Challenges included lack of knowledge among women and healthcare professionals relating to diabetes management and limited access to specialist pre-pregnancy care. Group meetings led to a consensus to develop a district-wide approach including healthcare professional and patient education and a structured approach to identification and optimisation of self-management, including contraception, in women of reproductive age with diabetes.

CONCLUSIONS

Sufficient evidence exists for consensus on a district-wide strategy to improve pre-pregnancy management among women with pre-existing diabetes.

Community-based integrated approach to changing women's family planning behaviour in Pakistan, 2014-2016

Setting: Karachi, Pakistan. Objective: To assess the effectiveness of a community-based integrated approach in changing women's behaviour regarding contraceptive use. Design: The Sukh Initiative is a multipronged approach with door-to-door services using community health workers to provide quality family planning/reproductive health services at both public and private facilities and a 24/7 family planning helpline service that provides youth skill-based education. Methods: Retrospective pre- and post-intervention data using samples of 5140 and 3810 women, respectively. Results: The contraceptive prevalence rate increased by 10.7%, from 42.3% at baseline to 53.0% mid-intervention, with an increase in use of modern contraceptive methods of 9.2%. A significant association was found between door-to-door counselling and the use of contraceptive methods (OR 3.4, 95%CL 2.9-4.1) and access to public and private facilities for modern contraceptives (OR 2.4, 95%CL 2.0-3.0). However, support group meetings and 24/7 helpline use did not show any association with use of contraceptive method. Conclusion: The study helped to increase access to and choice of family planning services through a community-based approach that successfully reduced unmet needs and improved continuity in contraceptive use.

Pregnant women's views on how to promote the use of a decision aid for Down syndrome prenatal screening: a theory-informed qualitative study

Background

For pregnant women and their partners, the decision to undergo Down syndrome prenatal screening is difficult. Patient decision aids (PtDA) can help them make an informed decision. We aimed to identify behaviour change techniques (BCTs) that would be useful in an intervention to promote the use of a PtDA for Down syndrome prenatal screening, and to identify which of these BCTs pregnant women found relevant and acceptable.

Methods

Using the Behaviour Change Wheel and the Theoretical Domains Framework, we conducted a qualitative descriptive study. First, a group of experts from diverse professions, disciplines and backgrounds (eg. medicine, engineering, implementation science, community and public health, shared decision making) identified relevant BCTs. Then we recruited pregnant women consulting for prenatal care in three clinical sites: a family medicine group, a birthing centre (midwives) and a hospital obstetrics department in Quebec City, Canada. To be eligible, participants had to be at least 18 years old, having recently given birth or at least 16 weeks pregnant with a low-risk pregnancy, and have already decided about prenatal screening. We conducted three focus groups and asked questions about the relevance and acceptability of the BCTs. We analysed verbatim transcripts and reduced the BCTs to those the women found most relevant and acceptable.

Results

Our group of experts identified 25 relevant BCTs relating to information, support, consequences, others’ approval, learning, reward, environmental change and mode of delivery. Fifteen women participated in the study with a mean age of 27 years. Of these, 67% (n = 10) were pregnant for the first time, 20% (n = 3) had difficulty making the decision to take the test, and 73% had made the decision with their partner. Of the 25 BCTs identified using the Behaviour Change Wheel, the women found the following 10 to be most acceptable and relevant: goal setting (behaviour), goal setting (results), problem solving, action plan, social support (general), social support (practical), restructuring the physical environment, prompts/cues, credible sources and modelling or demonstration of the behaviour.

Conclusions

An intervention to promote PtDA use among pregnant women for Down syndrome prenatal screening should incorporate the 10 BCTs identified.
