The Clinical Teaching Fellow role: exploring expectations and experiences.

BACKGROUND: Many UK junior doctors are now taking a year out of the traditional training pathway, usually before specialty training, and some choose to work as a clinical teaching fellow (CTF). CTFs primarily have responsibility for delivering hospital-based teaching to undergraduate medical students. Only a very small amount of literature is available regarding CTF posts, none of which has explored why doctors choose to undertake the role and their expectations of the job. This study aimed to explore the expectations and experiences of CTFs employed at NHS hospital Trusts in the West Midlands. METHODS: CTFs working in Trusts in the West Midlands region registered as students on the Education for Healthcare Professionals Post Graduate Certificate course at the University of Birmingham in August 2019 took part in a survey and a focus group. RESULTS: Twenty-eight CTFs participated in the survey and ten participated in the focus group. In the survey, participants reported choosing a CTF role due to an interest in teaching, wanting time out of training, and being unsure of which specialty to choose. Expectations for the year in post were directly related to reasons for choosing the role with participants expecting to develop teaching skills, and have a break from usual clinical work and rotations. The focus group identified five main themes relating to experiences starting their job, time pressures and challenges faced in post, how CTF jobs differed between Trusts, and future career plans. Broadly, participants reported enjoying their year in a post at a mid-year point but identified particular challenges such as difficulties in starting the role and facing time pressures in their day-to-day work. CONCLUSION: This study has provided a valuable insight into the CTF role and why doctors choose a CTF post and some of the challenges experienced, adding to the sparse amount of literature. Understanding post holders' experiences may contribute to optimisation of the role. Those employing CTFs should consider ensuring a formal handover process is in place between outgoing and incoming CTFs, having a lead person at their Trust responsible for evaluating changes suggested by CTFs, and the balance of contractual duties and personal development time.

The Clinical Teaching Fellow role: views of the Heads of Academy in the West Midlands.

BACKGROUND: Increasingly junior doctors are taking a year out of the traditional training pathway, and some opt to spend a year in a clinical teaching fellow (CTF) post. The CTF post mainly involves delivering hospital-based teaching to undergraduate medical students. In NHS hospital Trusts in the West Midlands, Heads of Academy (HoAs) have oversight of medical education at each Trust and therefore have responsibility for employing and directing the work of CTFs. Currently, only limited literature exists about the CTF role and exploring this from the point of view of different stakeholders in medical education is important in terms of contributing towards development of the role. This study aimed to explore the views of HoAs in the West Midlands region regarding CTFs employed at their Trusts. METHODS: All HoAs at the NHS Trust/teaching hospitals associated with the University of Birmingham were invited to take part in an in-depth interview about CTFs at their Trusts. Interviews were held via Zoom recorded using Zoom's recording functionality. Interview transcripts were then coded and analysed using thematic analysis. RESULTS: Seven out of 11 HoAs participated in an interview. Seven themes were identified: CTF duties/Job role, Relationship with students, Benefits of having CTFs, Challenges associated with CTFs, Popularity of the role, What Trust offers CTFs, and Future of the role. Primarily it was felt that having CTFs at their Trust was beneficial in terms of the amount of teaching they provide for medical students. The HoAs were keen to ensure the CTF posts were of maximum benefit to both the post holders and to the Trusts where they were based. The CTF role is one that they felt would continue and develop in the future. CONCLUSION: This study has provided the first insight into the CTF role from the point of view of senior doctors with responsibility for delivery of undergraduate medical education. The consistency and reliability of teaching provided by the CTFs was identified as a key benefit of the role. Future work exploring the role from the point of view of post holders themselves would be beneficial to contribute to development of the role.

Preparing for medical school selection: Exploring the complexity of disadvantage through applicant narratives.

Background: Despite a growing drive to improve diversity in medical schools, those from state schools and less-advantaged sociodemographic backgrounds remain underrepresented. We explore applicants' approaches to preparing for medical school selection, considering the complexity of sociodemographic disadvantage in this highly competitive process. Methods: Narrative interviews were undertaken with applicants to a United Kingdom medical school, exploring experiences of preparation for selection (n = 23). Participants were purposively sampled based on involvement in widening participation schemes, school background, gender, and ethnicity. Transcribed data were analyzed using Labov and Waletzky's analytic framework. Bourdieu's concepts of cultural capital and habitus provided a lens to constraints faced and variable experiences. This informed a consideration of the ways applicants approached and navigated their preparation, in the face of various constraints. Results: Constraints to resources and support were often apparent for those from state nonselective (SNS) schools. These applicants and those beginning their preparation later (12-18 months before application) appeared particularly vulnerable to myths and misunderstandings about the application process and appeared less confident and less discerning in their navigation of preparation. Some of the applicants, particularly those from independent and state selective schools, appeared confident and competent in navigating the complexities of the application process, while others (often from SNS schools) were more frequently lost or stressed by the process. Discussion: Those who lack particular preparatory tools or resources (materially, culturally, or perceptually) must "make do" as they prepare for medical school selection, In doing so, they may risk a haphazard, ill-informed or ill-equipped approach. Constraints to opportunities, more typically experienced by those from SNS schools, appeared to motivate the process of bricolage for a number of the applicants. Perversely, medical schools have introduced nonacademic requirements to level the playing field of disadvantage, yet applicants in this group appear to experience challenges as they prepare for selection.

An assessment of the impact of formal preparation activities on performance in the University Clinical Aptitude Test (UCAT): a national study.

BACKGROUND: Previous studies have shown performance in the University Clinical Aptitude Test (UCAT) to be associated with measures of candidate socio-economic advantage such as parental occupation and type of school attended. It is possible that access to preparation support and materials may in part explain these associations. In this paper we determine whether use of formal preparation resources is associated with higher UCAT scores and whether differences in use of preparation resources exist between socio-demographic groups. METHODS: After completing the 2017 UCAT UK school-leaver candidates (n = 14,332) were asked to answer a questionnaire regarding their use of official UCAT and commercial resources, school-based support, and time spent preparing. Multiple linear and logistic regression models were used to evaluate the associations between preparedness, demographic characteristics and UCAT performance. RESULTS: Five thousand, four hundred thirty-nine (38%) candidates responded to the questionnaire. Use of freely available UCAT official practice tests, paid commercial materials, attendance at school-based preparation courses and spending more time preparing were significantly associated with higher UCAT scores. Candidates who were from less deprived backgrounds and attending independent or grammar schools were significantly more likely to use paid commercial materials and spend longer preparing. CONCLUSIONS: Reported use of preparation resources varies between candidates from different socio-demographic backgrounds and is associated independently with performance in the UCAT. Increasing the availability of freely available resources may mitigate some of these differences.

Why do students struggle in their first year of medical school? A qualitative study of student voices.

BACKGROUND: Struggling at medical school incorporates academic failure, course disruption and early course exit. Struggling is usually multi-factorial involving academic, personal, financial and health factors. Struggling students may fail to engage with available support. First year students are particularly susceptible as they transition to university and a professional career. METHODS: The study aim was to explore medical students' own voices on struggling and assess how they match up to existing literature. During one academic year, all first year medical students at the University of Birmingham (UK) who opted to leave or were required to withdraw (n = 52) were asked to participate in an individual exit interview. Fifteen students responded and fourteen (27%) agreed to be interviewed. Interviews were face to face (n = 10), telephone (n = 3) and via email (n = 1). Interviews were unstructured and led by a general open question. Framework analysis identified key data themes. RESULTS: Students described year one of medical school as a critical transition. They simultaneously needed to adapt to being a university student, a medical student and a doctor. A six-group typology of students emerged, each of which struggled with one or more of these adaptations. The groups were: wrong degree choice, mental health problems, acute crisis, at capacity, slow starter and family rock. Some students experienced an isolated problem from within this typology. Most had a multi-factorial story of struggling. Mental health problems and acute crises were the most common issues. Early professional identity formation was a key hurdle. Help-seeking behaviours were varied. CONCLUSIONS: This study explores the narratives of medical students who struggled from an early stage and presents a data-driven typology of their issues. It advances existing qualitative understanding of this topic, which to date is predominantly derived from educator perceptions and not specific to early course issues. Although our results broadly cohere with existing knowledge, we also present novel findings which may reflect our focus on first year students. Issues around early professional identity formation may reflect the increasing emphasis on professionalism in medical school curricula. Listening to these narratives could help university staff to identify students at risk of struggling for targeted support.

A conceptual framework for understanding the mechanism of action of community health workers services: the centrality of social support.

OBJECTIVE: To propose an empirically derived and theoretically-informed mechanism to explain how Community Health Workers (CHWs) bring about health gain in clients in England. METHODS: We undertook in-depth interviews (n = 43) with CHWs and service staff working in four case studies selected using maximum variation sampling. Interviewees were encouraged to talk about the service, how they had become involved with the service, the CHW role and relationship with clients. FINDINGS: We identified the provision of social support to be central to the mechanism of CHW-mediated health gain. Appropriate social support provision comprised three inter-related elements; needs assessment, social support delivery and client engagement. This mechanism is dependent on the personal characteristics of CHWs and of the roles they are employed or volunteer to carry out. CONCLUSION: A range of CHW characteristics can influence the social support process, but these are context-dependent and move beyond simple notions of CHW similarity to the client. This finding has important policy implications for the development and implementation of CHW services in high income countries with super-diverse populations.

Cultural adaptation of a children's weight management programme: Child weigHt mANaGement for Ethnically diverse communities (CHANGE) study.

BACKGROUND: Childhood obesity prevalence continues to be at high levels in the United Kingdom (UK). South Asian children (mainly Pakistani and Bangladeshi origin) with excess adiposity are at particular risk from the cardiovascular consequences of obesity. Many community-based children's weight management programmes have been delivered in the UK, but none have been adapted for diverse cultural communities. The aim of the Child weigHt mANaGement for Ethnically diverse communities (CHANGE) study, was to culturally adapt an existing children's weight management programme for children aged 4-11 years so that the programme was more able to meet the needs of families from South Asian communities. METHODS: The adaptation process was applied to First Steps, an evidence informed programme being delivered in Birmingham (a large, ethnically diverse city). A qualitative study was undertaken to obtain the views of South Asian parents of children with excess weight, who had fully or partially attended, or who had initially agreed but then declined to attend the First Steps programme. The resulting data were integrated with current research evidence and local programme information as part of a cultural adaptation process that was guided by two theoretical frameworks. RESULTS: Interviews or focus groups with 31 parents in their preferred languages were undertaken. Themes arising from the data included the need for convenient timing of a programme in a close familiar location, support for those who do not speak English, the need to focus on health rather than weight, nutritional content that focuses on traditional and Western diets, more physical activity content, and support with parenting skills. The data were mapped to the Behaviour Change Wheel framework and Typology of Cultural Adaptation to develop an intervention programme outline. The research evidence and local programme information was then used in the detailed planning of the programme sessions. CONCLUSIONS: The process of cultural adaptation of an existing children's weight management programme resulted in a theoretically underpinned programme that is culturally adapted at both the surface and deep structural levels.

Who are community health workers and what do they do? Development of an empirically derived reporting taxonomy.

Objectives: To develop an empirically-informed reporting taxonomy for Community Health Worker (CHW) services to address concerns about the transparency and consistency of descriptions of these interventions in the existing literature. Methods: We undertook in-depth interviews (n = 43) with CHWs and service staff working in four case studies selected using maximum variation sampling. Interviewees were encouraged to talk about the service, how they had become involved with the service, the CHW role and relationship with clients. Results: Thematic analysis identified recurrent cross-case observations which we classed as 'who CHW are' and 'what CHW do'. CHW's personal characteristics comprised the sub-groups knowledge and skills, personal qualities, similarity to client and voluntary/paid status; role characteristics comprised time and continuity, settings, limited responsibility, core task and enacted philosophies. Conclusions: We have developed a conceptual framework for reporting CHW interventions based on the existing literature and our own empirical work. Compared with existing work in the field, the taxonomy uses nomenclature that minimizes current overlap and confusion, and provides a more complete description of CHW characteristics.

Measuring the impact of Health Trainers Services on health and health inequalities: does the service's data collection and reporting system provide reliable information?

Background: The Health Trainers Service is one of the few public health policies where a bespoke database-the Data Collection and Reporting System (DCRS)-was developed to monitor performance. We seek to understand the context within which local services and staff have used the DCRS and to consider how this might influence interpretation of collected data. Methods: In-depth case studies of six local services purposively sampled to represent the range of service provider arrangements, including detailed interviews with key stakeholders (n = 118). Results: Capturing detailed information on activity with clients was alien to many health trainers' work practices. This related to technical challenges, but it also ran counter to beliefs as to how a 'lay' service would operate. Interviewees noted the inadequacy of the dataset to capture all client impacts; that is, it did not enable them to input information about issues a client living in a deprived neighbourhood might experience and seek help to address. Conclusions: The utility of the DCRS may be compromised both by incomplete ascertainment of activity and by incorrect data inputted by some Health Trainers. The DCRS is also underestimate the effectiveness of work health trainers have undertaken to address 'upstream' factors affecting client health.

Development of a practice framework for improving nurses' responses to intimate partner violence.

AIMS AND OBJECTIVES: The aim of this article is to discuss critically the theoretical concepts of awareness, recognition and empowerment as manifested in intimate partner violence and to show how these can be translated into a practice framework for improving nurses' response. BACKGROUND: Intimate partner violence is a universal problem and is considered a significant public health issue. Nurses are in an ideal position to recognise and respond to intimate partner violence, but many lack confidence in this area of practice. In our previous empirical work, we identified three concepts through which nurses' responses to intimate partner violence can be understood: awareness, recognition and empowerment. In this article, we advance nursing knowledge by showing how these concepts can form a practice framework to improve nurses' responses to intimate partner violence. DESIGN: A discussion paper and development of a practice framework to improve nurses' responses to intimate partner violence. DISCUSSION: The framework comprises three principal needs of women and three related key requirements for nurses to meet these needs. Arising from these are a range of practice outcomes: enhanced understanding of intimate partner violence, increased confidence in recognising intimate partner violence, establishment of trusting relationships, increased likelihood of disclosure and optimised safety. CONCLUSIONS: Nurses sometimes lack confidence in recognising and responding to intimate partner violence. Awareness, recognition and empowerment are important concepts that can form the basis of a framework to support them. When nurses feel empowered to respond to intimate partner violence, they can work together with women to optimise their safety. RELEVANCE TO CLINICAL PRACTICE: Access to adequate and timely intimate partner violence education and training is important in improving nurses' responses to intimate partner violence. Getting this right can lead to enhanced safety planning and better health outcomes for women who experience intimate partner violence. Although difficult to measure as an outcome, nurses' improved responses can contribute to higher rates of referral for help and reduction in intimate partner violence rates.

Population-based longitudinal analyses of offer likelihood in UK medical schools: 1996-2012.

CONTEXT: The challenge of ensuring 'fair' selection processes confronts all medical schools around the globe. In the UK, historical analyses suggest applicants who are male, non-White, and from less advantaged socio-economic and school backgrounds have been less likely to be offered a place at medical school. We provide a contemporary population-based longitudinal analysis of the likelihood of receiving an offer to read medicine in the UK stratified by key socio-demographic characteristics. METHODS: We calculated the likelihood of receiving an offer among applicants to UK medical schools during 1996-2012, adjusted for sex, ethnicity, schooling, parental occupation, educational attainment and year of application. To investigate differences across time, models were fitted with interactions between application year and each of the other explanatory variables. RESULTS: There were 154 957 applicants, including 86 361 females (55.7%) and 68 596 males (44.3%). The majority of applicants were White (n = 94 519, 61.0%). The most common parental occupation category was higher managerial and professional (HMP) (n = 60 167, 38.8%) and 68 313 (44.1%) applicants came from grammar and independent schools. The likelihood of receiving an offer to study medicine varied three-fold across the study period, peaking in 2001 against the 1996 baseline (odds ratio [OR] 2.94, 95% confidence interval [CI] 2.78-3.11; p < 0.001). Throughout the study period, female applicants (OR 1.21, 95% CI 1.19-1.24; p < 0.001), those from more advantaged family backgrounds (OR 1.26, 95% CI 1.24-1.29; p < 0.001), and applicants who had attended independent or grammar schools (OR 1.25, 95% CI 1.23-1.28; p < 0.001) were more likely to receive an offer. Compared with Asian, Black and Other ethnic groups, White applicants had a greater likelihood of receiving an offer, with ORs of 1.56 (95% CI 1.54-1.61), 2.33 (95% CI 2.17-2.50) and 1.45 (95% CI 1.39-1.51), respectively. Differences in odds between White and non-White applicants reduced slightly during the study period but the overall advantage for White applicants persisted. The advantage for female applicants diminished markedly from 2007 onward. There was no clear trend in the advantage for students from HMP families, but from 2005 onward the odds of success for applicants with grammar and independent school backgrounds increased. CONCLUSIONS: Despite efforts to make selection processes more equitable, our findings suggest that persistent advantages remain for some demographic factors.

Longitudinal assessment of the impact of the use of the UK clinical aptitude test for medical student selection.

CONTEXT: Medical schools are increasingly using novel tools to select applicants. The UK Clinical Aptitude Test (UKCAT) is one such tool and measures mental abilities, attitudes and professional behaviour conducive to being a doctor using constructs likely to be less affected by socio-demographic factors than traditional measures of potential. Universities are free to use UKCAT as they see fit but three broad modalities have been observed: 'borderline', 'factor' and 'threshold'. This paper aims to provide the first longitudinal analyses assessing the impact of the different uses of UKCAT on making offers to applicants with different socio-demographic characteristics. METHODS: Multilevel regression was used to model the outcome of applications to UK medical schools during the period 2004-2011 (data obtained from UCAS), adjusted for sex, ethnicity, schooling, parental occupation, educational attainment, year of application and UKCAT use (borderline, factor and threshold). RESULTS: The three ways of using the UKCAT did not differ in their impact on making the selection process more equitable, other than a marked reversal for female advantage when applied in a 'threshold' manner. Our attempt to model the longitudinal impact of the use of the UKCAT in its threshold format found again the reversal of female advantage, but did not demonstrate similar statistically significant reductions of the advantages associated with White ethnicity, higher social class and selective schooling. CONCLUSION: Our findings demonstrate attenuation of the advantage of being female but no changes in admission rates based on White ethnicity, higher social class and selective schooling. In view of this, the utility of the UKCAT as a means to widen access to medical schools among non-White and less advantaged applicants remains unproven.

Parent and child perceptions of school-based obesity prevention in England: a qualitative study.

BACKGROUND: Schools are key settings for childhood obesity prevention, and the location for many intervention studies. This qualitative study aims to explore parent and child experiences of the WAVES study obesity prevention intervention, in order to gain understanding of the mechanisms by which the intervention results in behaviour change, and provide context to support interpretation of the main trial results. METHODS: Focus groups were held with 30 parents and 62 children (aged 6-7 years) from primary schools in the West Midlands, UK. Data analysis (conducted using NVivo 10) was guided by the Framework Approach. RESULTS: Three over-arching themes were identified: 'Impact', 'Sustainability' and 'Responsibilities', under which sub-themes were determined. Participants were supportive of the school-based intervention. Parental involvement and the influential role of the teacher were seen as key ingredients for success in promoting consistent messages and empowering some parents to make positive behavioural changes at home. Parents recognised that whilst they held the primary responsibility for obesity prevention in their children, they faced a number of barriers to healthier lifestyles, and agreed that schools have an important role to play. CONCLUSIONS: This study enabled us to better understand aspects of the WAVES study intervention programme that have the potential to initiate positive behaviour changes in families, and indicated that a combination of pathways influenced such changes. Pathways included: increasing capability through improving knowledge and skills of children and parents; increasing motivation through parental empowerment and role modelling; and the direct provision of opportunities to lead healthier lifestyles. Strategies to sustain behaviour changes, and the school role in supporting these, are important considerations.

A cluster-randomised controlled trial to assess the effectiveness and cost-effectiveness of a childhood obesity prevention programme delivered through schools, targeting 6-7 year old children: the WAVES study protocol.

BACKGROUND: There is some evidence that school-based interventions are effective in preventing childhood obesity. However, longer term outcomes, equity of effects and cost-effectiveness of interventions have not been assessed. The aim of this trial is to assess the clinical and cost-effectiveness of a multi-component intervention programme targeting the school and family environment through primary schools, in preventing obesity in 6-7 year old children, compared to usual practice. METHODS: This cluster randomised controlled trial is set in 54 primary schools within the West Midlands, UK, including a multi-ethnic, socioeconomically diverse population of children aged 6-7 years. The 12-month intervention consists of healthy diet and physical activity promotion. These include: activities to increase time spent doing physical activity within the school day, participation in the 'Villa Vitality' programme (a programme that is delivered by an iconic sporting institution (Aston Villa Football Club), which provides interactive learning opportunities for physical activity and healthy eating), healthy cooking skills workshops in school time for parents and children, and provision of information to families signposting local leisure opportunities. The primary (clinical) outcome is the difference in body mass index (BMI) z-scores between arms at 3 and 18 months post-intervention completion. Cost per Quality Adjusted Life Year (QALY) will also be assessed. The sample size estimate (1000 children split across 50 schools at follow-up) is based on 90% power to detect differences in BMI z-score of 0.25 (estimated ICC ≤ 0.04), assuming a correlation between baseline and follow-up BMI z-score of 0.9. Treatment effects will be examined using mixed model ANCOVA. Primary analysis will adjust for baseline BMI z-score, and secondary analysis will adjust for pre-specified baseline school and child level covariates. DISCUSSION: The West Midlands ActiVe lifestyle and healthy Eating in School children (WAVES) study is the first trial that will examine the cost-effectiveness and long term outcomes of a childhood obesity prevention programme in a multi-ethnic population, with a sufficient sample size to detect clinically important differences in adiposity. The intervention was developed using the Medical Research Council framework for complex interventions, and outcomes are measured objectively, together with a comprehensive process evaluation. TRIAL REGISTRATION: Current Controlled Trials ISRCTN97000586 (registered May 2010).

The challenge of implementing peer-led interventions in a professionalized health service: a case study of the national health trainers service in England.

UNLABELLED: Policy Points: In 2004, England's National Health Service introduced health trainer services to help individuals adopt healthier lifestyles and to redress national health inequalities. Over time these anticipated community-focused services became more NHS-focused, delivering "downstream" lifestyle interventions. At the same time, individuals' lifestyle choices were abstracted from the wider social determinants of health and the potential to address inequalities was diminished. While different service models are needed to engage hard-to-reach populations, the long-term sustainability of any new service model depends on its aligning with the established medical system's characteristics. CONTEXT: In 2004, the English Public Health White Paper Choosing Health introduced "health trainers" as new members of the National Health Service (NHS) workforce. Health trainers would offer one-to-one peer-support to anyone who wished to adopt and maintain a healthier lifestyle. Choosing Health implicitly envisaged health trainers working in community settings in order to engage "hard-to-reach" individuals and other groups who often have the poorest health but who engage the least with traditional health promotion and other NHS services. METHODS: During longitudinal case studies of 6 local health trainer services, we conducted in-depth interviews with key stakeholders and analyzed service activity data. FINDINGS: Rather than an unproblematic and stable implementation of community-focused services according to the vision in Choosing Health, we observed substantial shifts in the case studies' configuration and delivery as the services embedded themselves in the local NHS systems. To explain these observations, we drew on a recently proposed conceptual framework to examine and understand the adoption and diffusion of innovations in health care systems. CONCLUSIONS: The health trainer services have become more "medicalized" over time, and in doing so, the original theory underpinning the program has been threatened. The paradox is that policymakers and practitioners recognize the need to have a different service model for traditional NHS services if they want hard-to-reach populations to engage in preventive actions as a first step to redress health inequalities. The long-term sustainability of any new service model, however, depends on its aligning with the established medical system's (ie, the NHS's) characteristics.

Process evaluation design in a cluster randomised controlled childhood obesity prevention trial: the WAVES study.

BACKGROUND: The implementation of a complex intervention is heavily influenced by individual context. Variation in implementation and tailoring of the intervention to the particular context will occur, even in a trial setting. It is recognised that in trials, evaluating the process of implementation of a complex intervention is important, yet process evaluation methods are rarely reported. The WAVES study is a cluster randomised controlled trial to evaluate the effectiveness of an obesity prevention intervention programme targeting children aged 6-7 years, delivered by teachers in primary schools across the West Midlands, UK. The intervention promoted activities encouraging physical activity and healthy eating. This paper presents the methods used to assess implementation of the intervention. METHODS: Previous literature was used to identify the dimensions of intervention process and implementation to be assessed, including adherence, exposure, quality of delivery, participant responsiveness, context, and programme differentiation. RESULTS: Multiple methods and tools were developed to capture information on all these dimensions. These included observations, logbooks, qualitative evaluation, questionnaires and research team reflection. DISCUSSION: Data collection posed several challenges, predominantly when relying on teachers to complete paperwork, which they saw as burdensome on top of their teaching responsibilities. However, the use of multiple methods helped to ensure data on each dimension, where possible, was collected using more than one method. This also allowed for triangulation of the findings when several data sources on any one dimension were available. CONCLUSIONS: We have reported a comprehensive approach to the assessment of the implementation and processes of a complex childhood obesity prevention intervention within a cluster randomised controlled trial. These approaches can be transferred and adapted for use in other complex intervention trials. TRIAL REGISTRATION NUMBER: ISRCTN97000586.

Development of a childhood obesity prevention programme with a focus on UK South Asian communities.

OBJECTIVE: We report the development of a childhood obesity prevention intervention for UK South Asian primary school-aged children, guided by the UK Medical Research Council (MRC) framework for complex intervention development and evaluation. METHODS: We combined information gained from a literature review, stakeholder focus groups, an expert group, review of local resources and mapping to the Analysis Grid for Environments Linked to Obesity (ANGELO framework) in an intervention development process. The study took place in 2007 in Birmingham, UK. RESULTS: Contextual information from the stakeholder focus groups was essential for informing intervention development. The expert group defined guiding principles for the intervention. Informing intervention design by assessing existing local resources addressed intervention sustainability. The use of the ANGELO framework ensured a comprehensive environmental approach to intervention development. The intervention consisted of two broad processes; increasing children's physical activity levels through school, and increasing skills of families through activity-based learning. The developed intervention is being evaluated in a major study. CONCLUSIONS: The intervention development process has resulted in a tailored intervention programme to prevent childhood obesity in UK South Asian communities, but also intervention processes that could be applied to other communities and tailored to local context.

Contextual influences on the development of obesity in children: a case study of UK South Asian communities.

OBJECTIVE: An advocated approach to childhood obesity prevention research is the use of local community knowledge to inform intervention development. This paper demonstrates the value of accessing such local knowledge, and discusses how this information fits with existing conceptual models of childhood obesity. METHODS: A series of 9 focus groups were run in 2007 with 68 local community stakeholders (including parents, school staff, community leaders and health and local government representatives) from 8 South Asian communities in Birmingham, UK to explore perceptions of factors contributing to the development of childhood obesity. RESULTS: Perceptions of causal influences were grouped into several contexts, from the individual to the macro-level, that influence diet and physical activity. Specific cultural contextual data emerged that may explain decisions around physical activity and food intake of children within these communities. Assumptions made about South Asian communities were frequently contested. CONCLUSIONS: In order to truly understand the contextual influences on childhood obesity in target communities, it is necessary to access knowledge from local community members. Existing conceptual models of childhood obesity do not bring the role of cultural factors to the fore, but this context needs to be explicitly considered in the development of childhood obesity interventions.

What are the challenges to the Big Society in maintaining lay involvement in health improvement, and how can they be met?

The UK Coalition Government's Big Society policy has highlighted the value of the contribution that local people can make to well-being in their own communities, and plans to increase the contribution of community groups and third sector organizations in delivering services. This paper attempts to unpick some of the challenges to delivering health improvement interventions within the Big Society framework, and offers suggestions to reduce risk and preserve the value of the unique contribution that local people can make. The challenges identified are: supporting and developing skills in social enterprise; demonstrating effectiveness to commissioners; supporting local enterprise while mindful of inequality; guarding against the third sector losing its dynamism; using volunteers to replace or complement existing services. We conclude that the drive to increase community sustainability through the involvement of individuals is laudable, and responds to potential flaws in the welfare state. In order to protect the most vulnerable, and ensure equity, any change will take time and resources. More efficient ways of meeting society's needs must be sought, but we recommend that a stepwise, supported and appropriately evaluated approach is essential, and equity of provision across communities and organizations must be a primary concern.
