A novel peer-support intervention using motivational interviewing for breastfeeding maintenance: a UK feasibility study

Lessons for the UK on implementation and evaluation of breastfeeding support: evidence syntheses and stakeholder engagement

Background

Breastfeeding impacts positively on multiple health outcomes, but < 50% of UK women breastfeed at 8 weeks. Women with long-term conditions face additional challenges in breastfeeding.

Objectives

To synthesise global and UK evidence to co-create an implementation and evaluation toolkit for cost-effective breastfeeding support in the NHS.

Design

Evidence syntheses with stakeholder engagement.

Review methods

Systematic reviews examined effectiveness of breastfeeding support for (1) healthy women and (2) women with long-term conditions using Cochrane Pregnancy and Childbirth Group methods. Mixed-methods systematic reviews synthesised process evaluations of effective breastfeeding support interventions for healthy women and experiences of receiving/providing support for breastfeeding women with long-term conditions. Cross-study synthesis integrated qualitative and quantitative findings. Systematic reviews synthesised evidence on the incremental costs and cost-effectiveness of breastfeeding support following National Institute for Health and Care Excellence guidance. All searches were conducted from May 2021 to October 2022. Stakeholder engagement and toolkit development comprised online discussions, a modified Delphi study, focus groups and four workshops. Participants were 23 stakeholders, 16 parents in the parents' panels, 15 women in the focus groups and 87 stakeholders who attended the workshops.

Results

We found considerably more interventions designed for healthy women (review 1) than aimed at women with long-term conditions (reviews 1 and 4); approximately half of the studies were targeted at groups at higher risk of poor breastfeeding outcomes, and the impact of support may be different in these populations. Despite this, studies from review 2 found that women perceived the provision of support as positive, important and needed. Studies from review 5 echoed a range of suggestions from participants regarding potential strategies to improve breastfeeding support, with the most widely reported being the need to acknowledge the role and influence of other sources of support (e.g. partners, family, friends, peers, external professionals, web-based resources) and involving these sources in the provision of breastfeeding support for women with long-term conditions. In reviews 3 and 6, there was uncertainty about the cost-effectiveness of breastfeeding support interventions due to the limited number of studies and lack of good-quality evidence.

Limitations

There was a lack of evidence for the effectiveness and cost-effectiveness of breastfeeding interventions in the UK. There was often insufficient information reported about intervention characteristics.

Conclusions

'Breastfeeding only' support probably reduces the number of women stopping any or exclusive breastfeeding. The evidence for 'breastfeeding plus' interventions is less consistent, but these may reduce the number of women stopping exclusive breastfeeding at 4-6 weeks and at 6 months. We found no evidence of differential intervention effects regarding mode of provision or provider. Cost-effectiveness is uncertain due to the lack of good-quality evidence. Key enablers of successful implementation were responsiveness and tailoring of interventions to both women's and supporters' needs. Breastfeeding support as delivered in the included studies probably has little to no effect on breastfeeding outcomes for women with long-term conditions. The mixed-methods synthesis and stakeholder work identified that existing interventions may not address the complex needs of these women. The main study output is a co-produced toolkit to guide implementation and evaluation of breastfeeding support services in the UK.

Future work

Evaluation of breastfeeding support for all women, particularly those at risk of poor breastfeeding outcomes (e.g. long-term conditions, deprivation). This could involve tailoring the toolkit to local contexts via implementation and effectiveness studies or using quality improvement studies.

Text message conversations between peer supporters and women to deliver infant feeding support using behaviour change techniques: A qualitative analysis

OBJECTIVE

To analyse text message conversations between peer supporters (called Infant Feeding Helpers - IFHs) and new mothers using qualitative methods to understand how peer support can influence and support women's feeding experiences.

DESIGN

Qualitative analysis of text messages conversations using both inductive thematic and deductive content approaches to coding. Thematic analysis of the text message transcripts and deductive content analysis was used to code if Behaviour Change Techniques (BCTs) were employed by IFHs in their interactions with women. BCTs coded in text messages were then compared with those tabulated from antenatal meeting recordings and documented in interview transcripts.

PARTICIPANTS AND SETTING

18 primiparous women and 7 Infant Feeding Helpers from one community site in South-West England.

FINDINGS

Three key themes were identified in the18 text message conversations (1679 texts): 'breastfeeding challenges', 'mother-centred conversations', and 'emotional and practical support'. The core BCTs of 'social support' and 'changing the social environment' were found at least once in 17 (94 %) and 18 (100 %) text message conversations respectively. Meanwhile, 'instruction to perform the behaviour' was used at least once in over 50 % of conversations. Generally, the use of BCTs was greatest between birth and two weeks during a period of daily texts when women reported many feeding challenges. The number and range of BCTs used in text messages were similar to those documented in audio-recorded meetings and interview accounts.

CONCLUSION AND IMPLICATIONS

Infant Feeding Helpers were able to provide engaging and successful breastfeeding peer support through text messages. Messaging was shown to be an appropriate and accessible method of delivering BCTs focussing on 'social support' and 'changing the social environment'. Peer supporters delivering BCTs via text messages is acceptable and appropriate to use if in-person support is limited due to unforeseen circumstances such as the COVID-19 pandemic.

Investigating the influence of breastfeeding on asthma in children under 12 years old in the UK Biobank

Background

Childhood-onset asthma (COA) has become a major and growing problem worldwide and imposes a heavy socioeconomic burden on individuals and families; therefore, understanding the influence of early-life experiences such as breastfeeding on COA is of great importance for early prevention.

Objectives

To investigate the impact of breastfeeding on asthma in children under 12 years of age and explore its role at two different stages of age in the UK Biobank cohort.

Methods

A total of 7,157 COA cases and 158,253 controls were obtained, with information regarding breastfeeding, COA, and other important variables available through questionnaires. The relationship between breastfeeding and COA were examined with the logistic regression while adjusting for available covariates. In addition, a sibling analysis was performed on 398 pairs of siblings to explain unmeasured family factors, and a genetic risk score analysis was performed to control for genetic confounding impact. Finally, a power evaluation was conducted in the sibling data.

Results

In the full cohort, it was identified that breastfeeding had a protective effect on COA (the adjusted odds ratio (OR)=0.875, 95% confidence intervals (CIs): 0.831~0.922; P=5.75×10^-7). The impact was slightly pronounced in children aged 6-12 years (OR=0.852, 95%CIs: 0.794~0.914, P=7.41×10^-6) compared to those aged under six years (OR=0.904, 95%CIs: 0.837~0.975, P=9.39×10^-3), although such difference was not substantial (P=0.266). However, in the sibling cohort these protective effects were no longer significant largely due to inadequate samples as it was demonstrated that the power was only 23.8% for all children in the sibling cohort under our current setting. The protective effect of breastfeeding on COA was nearly unchanged after incorporating the genetic risk score into both the full and sibling cohorts.

Conclusions

Our study offered supportive evidence for the protective effect of breastfeeding against asthma in children less than 12 years of age; however, sibling studies with larger samples were warranted to further validate the robustness our results against unmeasured family confounders. Our findings had the potential to encourage mothers to initiate and prolong breastfeeding.

Implementing a successful proactive telephone breastfeeding peer support intervention: volunteer recruitment, training, and intervention delivery in the RUBY randomised controlled trial

BACKGROUND

The RUBY randomised controlled trial demonstrated the benefit of proactive telephone peer support in promoting breastfeeding continuation in a setting with high breastfeeding initiation, where typically this is difficult to achieve. This paper describes the implementation and delivery of the peer support intervention with a focus on recruitment, training, and support of peer volunteers, and includes a description of the key components of the calls.

METHODS

Data collection occurred between December 2012 and June 2016 in Melbourne, Australia. Volunteers completed enrolment forms at the training session and recorded data related to each call in a Call Log maintained for each mother supported. Data were summarised using descriptive statistics and responses to open-ended questions analysed using content analysis.

RESULTS

A total of 693 women expressed interest in the peer support role, with 246 completing training, that is, 95% of whom supported at least one mother. Each supported a mean of two mothers (range 1 to 11). Training session topics included respecting individual values, using positive language, confidence building, active listening, empathetic support, and normal baby behaviour. There were 518 periods of support where at least one call was made between a volunteer and a mother to whom she was allocated. Of the 518 periods of support, 359 Call Logs (69%) were returned. The 359 call logs recorded a total of 2398 calls between peers and mothers. Call length median duration was 12 min (range 1 to 111 min). Volunteers perceived the most valued aspects of the calls were the provsion of 'general emotional support' (51%) and 'general information/discussion about breastfeeding' (44%). During the first call, mothers raised questions about 'nipple pain/ damage' (24%) and 'general breastfeeding information' (23%). At ≥12 weeks postpartum, issues raised related to 'normal infant behaviour' (22%), 'feed frequency' (16%), and 'general breastfeeding information' (15%). Volunteers referred women to other resources during 28% of calls, most commonly to the Australian Breastfeeding Association.

CONCLUSIONS

Our findings demonstrate that the RUBY trial was feasible and sustainable in terms of recruiting volunteers who were willing to participate in training and who proceeded to provide peer support. Call content was responsive to the evolving breastfeeding information needs of mothers and the provision of emotional support was perceived by volunteers to be important.

Designing a model of breastfeeding support in Australia: An appreciative inquiry approach

In Australia, one of the most frequent reasons for not breastfeeding is a previously unsuccessful experience. This qualitative study used an appreciative inquiry approach to co-design a model of peer and professional breastfeeding support, in a metropolitan area of New South Wales (NSW) Australia, in collaboration with women who have had previous negative experiences of breastfeeding. In total, 30 mothers, health professionals and peer supporters participated in a two-part study, involving interviews and a collaborative workshop. The data were analysed using content analysis. The appreciative inquiry approach led to a solution focused attitude among participants and a commitment to improving breastfeeding support. We noted a level of apathy when the participant groups were interviewed individually prior to the collective workshop. During the collaborative workshop, all three participant groups came together to look at what was currently working well and designed improvements for the future. Midwifery care was identified as important for the start of the breastfeeding journey, during pregnancy and for the first 1-2 weeks after birth, but thereafter it was community and trained peer counsellors who were prioritised for breastfeeding support. Participants identified the need for a variety of support options including face-to-face meetings, Skype meetings, phone calls and/or texting. Workshop participants emphasised the need for women, especially those with previous negative experiences, to be linked in with their local peer support community group. An appreciative inquiry approach brought together all key stakeholders to develop practice-based change which included the end user and care providers. The collaborative workshop enabled participants to come together, as individuals, rather than as designated health professionals or trained peer counsellors, or breastfeeding women with negative experiences. This led to a unified approach and a harnessing of collective energy to initiate positive change.

The Effect of Motivational Interviewing on Self-Efficacy and Continuation of Exclusive Breastfeeding Rates: A Quasi-Experimental Study

Background: Self-efficacy is a decisive psychological and motivational factor in maintaining exclusive breastfeeding (EBF). The aim of this study was to explore the impact of motivational interviewing (MI) on EBF self-efficacy and EBF in primiparous women. Materials and Methods: This quasi-experimental study was conducted on 140 primiparous women admitted to a number of comprehensive health centers in Zahedan in 2019. The health centers were determined through multistage random sampling, and the subjects were selected from each center using convenience sampling. The selected women were equally divided into the intervention and control groups. The two groups took the pretest by filling out a demographic questionnaire and a breastfeeding self-efficacy questionnaire. The intervention group attended four 45- to 60-minute MI sessions on breastfeeding. The EBF continuation sheet and the breastfeeding self-efficacy questionnaire were filled out 6 months postpartum. Data were analyzed in SPSS 22 using paired t-test, independent t-test, chi-square test, and covariance analysis. Results: Based on the results, the mean and standard deviation of the number of EBF days were significantly higher in the intervention group (137.68 ± 65.50) compared with that of the control group (99.51 ± 80.62). In addition, the mean score of breastfeeding self-efficacy after MI was significantly different between the two groups (p = 0.0001). Conclusion: Because of the significantly positive impact of MI on enhancing EBF self-efficacy and continuation, it is recommended to integrate this counseling strategy into the care programs designed for women in pregnancy and even postpartum period.

An assets-based intervention before and after birth to improve breastfeeding initiation and continuation: the ABA feasibility RCT

Background

The UK has low levels of breastfeeding initiation and continuation, with evident socioeconomic disparities. To be inclusive, peer-support interventions should be woman-centred rather than breastfeeding-centred. Assets-based approaches to public health focus on the positive capabilities of individuals and communities, rather than their deficits and problems. The Assets-based feeding help Before and After birth (ABA) intervention offers an assets-based approach based on behaviour change theory.

Objective

To investigate the feasibility of delivering the ABA infant feeding intervention in a randomised controlled trial.

Design

This was an individually randomised controlled feasibility trial; women were randomised in a 1 : 1 ratio to either the intervention group or the comparator (usual care) group.

Setting

Two separate English sites were selected because they had an existing breastfeeding peer support service, relatively high levels of socioeconomic disadvantage and low rates of breastfeeding.

Participants

Women aged ≥ 16 years who were pregnant with their first child, irrespective of feeding intention (n = 103), were recruited by researchers in antenatal clinics.

Interventions

Proactive, woman-centred support, using an assets-based approach and including behaviour change techniques, was provided by an infant-feeding helper (a breastfeeding peer supporter trained in the ABA intervention) and delivered through face-to-face contact, telephone conversations and text messages. The intervention commenced at around 30 weeks’ gestation and could continue until 5 months postnatally.

Main outcome measures

The main outcome measures were feasibility of intervention delivery with the requisite intensity and duration; acceptability to women, infant-feeding helpers and maternity services; and feasibility of a future randomised controlled trial. Outcomes included recruitment rates and follow-up rates at 3 days, 8 weeks and 6 months postnatally, and outcomes for a future full trial were collected via participant questionnaires. A mixed-methods process evaluation included qualitative interviews with women, infant-feeding helpers and maternity services; infant-feeding helper logs; and audio-recordings of antenatal contacts to check intervention fidelity.

Results

Of the 135 eligible women approached, 103 (76.3%) agreed to participate. The study was successful in recruiting teenagers (8.7%) and women living in areas of socioeconomic disadvantage (37.3% resided in the most deprived 40% of small areas in England). Postnatal follow-up rates were 68.0%, 85.4% and 80.6% at 3 days, 8 weeks and 6 months, respectively. Feeding status at 8 weeks was obtained for 95.1% of participants. Recruitment took place from February 2017 until August 2017. It was possible to recruit and train existing peer supporters to the infant-feeding helper role. The intervention was delivered to most women with relatively high fidelity. Among the 50 women in the intervention group, 39 received antenatal visits and 40 received postnatal support. Qualitative data showed that the intervention was acceptable. There was no evidence of intervention-related harms.

Limitations

Birth notification delays resulted in delays in the collection of postnatal feeding status data and in the offer of postnatal support. In addition, the intervention needs to better consider all infant-feeding types and did not adequately accommodate women who delivered prematurely.

Conclusion

It is feasible to deliver the intervention and trial.

Future work

The intervention should be tested in a fully powered randomised controlled trial.

Using the behaviour change wheel to explore infant feeding peer support provision; insights from a North West UK evaluation

Background

Breastfeeding peer support is advocated in national and international guidelines, but the evidence base is mixed. In the UK, breastfeeding peer support was found to be ineffective in randomised controlled trials, while women report positive impacts on breastfeeding experiences in qualitative studies. A key criticism levied against breastfeeding peer support is the lack of theory underpinning intervention design. Here we use the Behaviour Change Wheel to structure the analysis of evaluation data from an infant feeding peer support service in one area in North West England. We aimed to provide theoretically informed insights into how peer support can be operationalised to influence women's breastfeeding experiences.

Methods

A 2 year mixed-methods evaluation (2014-2016) comprised surveys and interviews (individual or group) with peer supporters, health and community professionals, project leads and women, and routinely collected infant feeding data. We used the three layers (policies, intervention functions and behaviour-related components) of the Behaviour Change Wheel to structure and interpret the data.

Results

Overall data comprised 23 interviews (n = 14 - individual; n = 9 - group) and 409 completed surveys. The findings are presented in three sections. First, the 'policies' (outer) layer of the Behaviour Change Wheel provides insights into the existing context, infrastructure and resources that underpinned peer support delivery. Then the second (intervention functions) and inner (behaviour components) layers of the Behaviour Change Wheel are used to present three themes, 'developing capabilities for infant feeding', 'motivating guidance and support' and 'opportunities for support'. These findings highlight that a peer support service delivered in a context of effective interdisciplinary partnerships, Baby Friendly Initiative accreditation, and flexible service planning, with peer support provided via different types of instrumental, social, practical and emotional support was perceived to be highly beneficial on women's breastfeeding experiences. In the final section key challenges faced by the service are outlined.

Conclusion

While gaps and areas for development were highlighted, the service enhanced women's capabilities, motivations and opportunities for breastfeeding. These theoretically informed insights into an organic and responsive peer support service help build the evidence base for breastfeeding peer support and to identify positive delivery features for future testing.

"Focusing" in Motivational Interviewing: development of a training tool for practitioners

Rationale aims and objectives

Motivational Interviewing (MI) is an individual-level approach to behaviour change that has been evaluated in over 600 randomised clinical trials across multiple settings. Increasingly, research efforts focus on how MI works and how it can best be integrated into public health and clinical programmes. As the application of MI expands, a key integration challenge involves specifying the focus of a conversation such that a practitioner might ignite and intensify a patient's internal motivation for change related to that focus. At present, this challenge is poorly conceptualised. We aimed to clarify the construct of "focusing" and to develop a practical tool that can be used to develop and assess practitioner competence.

Method

First we reviewed validated MI measures to elucidate current conceptualisations of focusing. Second, we identified practitioner speech acts that led to topic transitions. We then drafted the first version of MIFI. A gold standard rater, together with one expert MI and 3 non-expert MI raters, each used MIFI to coded 20 audio recordings from a feasibility study of MI and breastfeeding maintenance (n=170 observations). Internal consistency and inter-rater reliability analyses were conducted.

Results

Published MI measures include 'focusing' as a strategy to agree a target change or to hold attention on that change target. We observed practitioners create or shift focus using 4 skills: questions, listening statements, giving information or meta-statements. Moderate to strong correlations were demonstrated between 4 of 5 global measures on the MIFI. Reliability estimates were good to excellent overall (5 coder ICCs>0.65), fair to excellent for the non-expert coding group (ICCs>0.55) and for the best coding pair (MI expert and non-expert ICCs >0.52).

Conclusion

We offer conceptual clarity about focusing in MI and have developed a tool to train practitioners in "focusing" when integrating MI into healthcare and public health interventions.

A realist review of one-to-one breastfeeding peer support experiments conducted in developed country settings

The World Health Organisation guidance recommends breastfeeding peer support (BFPS) as part of a strategy to improve breastfeeding rates. In the UK, BFPS is supported by National Institute for Health and Care Excellence guidance and a variety of models are in use. The experimental evidence for BFPS in developed countries is mixed and traditional methods of systematic review are ill-equipped to explore heterogeneity, complexity, and context influences on effectiveness. This review aimed to enhance learning from the experimental evidence base for one-to-one BFPS intervention. Principles of realist review were applied to intervention case studies associated with published experimental studies. The review aimed (a) to explore heterogeneity in theoretical underpinnings and intervention design for one-to-one BFPS intervention; (b) inform design decisions by identifying transferable lessons developed from cross-case comparison of context-mechanism-outcome relationships; and (c) inform evaluation design by identifying context-mechanism-outcome relationships associated with experimental conditions. Findings highlighted poor attention to intervention theory and considerable heterogeneity in BFPS intervention design. Transferable mid-range theories to inform design emerged, which could be grouped into seven categories: (a) congruence with local infant feeding norms, (b) integration with the existing system of health care, (c) overcoming practical and emotional barriers to access, (d) ensuring friendly, competent, and proactive peers, (e) facilitating authentic peer-mother interactions, (f) motivating peers to ensure positive within-intervention amplification, and (g) ensuring positive legacy and maintenance of gains. There is a need to integrate realist principles into evaluation design to improve our understanding of what forms of BFPS work, for whom and under what circumstances.
