'For me it's just the conversation:' responsive feeding influences among early childhood educators.

OBJECTIVE: Early learning and childcare (ELCC) programmes play an important role in shaping children's eating behaviours and long-term health by establishing a responsive feeding environment that encompasses not only mealtime behaviours but also extends to play activities and language used throughout the day. Despite their potential benefits, many ELCC centres do not consistently implement responsive feeding behaviours, facing challenges with organisational and behavioural changes within these environments. This study aims to identify influences on responsive feeding behaviours among early childhood educators prior to an intervention. DESIGN: A qualitative study guided by the Behaviour Change Wheel framework and Capability Opportunity Motivation - Behaviour (COM-B) model. Semi-structured interviews and focus groups were conducted, recorded and transcribed verbatim. Thematic analysis was employed to identify themes, categorising them within the corresponding COM-B domains. SETTING: Canada. PARTICIPANTS: Forty-one ELCC staff in various roles across eight centres from two provinces in eastern Canada. RESULTS: Fifteen influences, spanning across all six domains of the COM-B model, were identified, highlighting gaps in educators' knowledge and skills, varied approaches to food and feeding, and the interactions with children, parents, and co-workers on mealtimes dynamics. Additionally, costs, centre location and other physical resources emerged as enabling opportunities for responsive feeding behaviours. CONCLUSIONS: These findings offer a comprehensive exploration of the diverse factors influencing responsive feeding behaviours among educators, each varying in its potential for future behaviour change intervention.

Personalized messaging enhances hospital debt collection while prosocial appeals fail: Evidence from a field experiment.

Objective: This study aimed to understand how different communication strategies influence patients' behaviour in paying unpaid hospital bills. The research focused on a healthcare system where patients have to pay a significant portion of their medical costs out-of-pocket. Methods: The research was conducted in collaboration with a debt collection agency in Latvia. The field experiment involved 9196 individuals with unpaid hospital bills. These individuals received randomly assigned reminders through mobile text messages and e-mails. The study compared the effectiveness of personalized messages, which included the recipient's name, with generic reminders and messages that appealed to social norms or public good contributions. Results: The findings revealed that personalized messages, specifically those that included the recipient's name, significantly improved payment rates compared with generic reminders. Conversely, messages that used social norms or public good appeals did not have a significant impact on payment rates. Conclusions: The study highlights the importance of personalized communication strategies in improving hospital debt collection. Even simple, cost-effective modifications in communication, like adding the recipient's name, can significantly enhance payment compliance. This approach not only keep the financial books of healthcare providers balanced but also suggests that personalized strategies can be extended to other areas of healthcare management. However, while these findings are promising, they indicate that more personalized and nuanced communication strategies are needed to address the broader issue of unpaid hospital bills effectively.

Improving the Use of Sensory Approaches in an Acute Inpatient Mental Health Unit Using a Co-Designed Multifaceted Implementation Strategy.

Despite the therapeutic benefits of sensory approaches being well documented, little research has focused on improving their implementation in acute mental health units. The use of implementation frameworks to improve the use of evidence-based practices has shown promising results in healthcare; however, there is little evidence for their use in acute mental health units. A pre-post comparison design was used to determine the effect of an 11-month co-designed theory-informed multifaceted implementation strategy on the use of sensory approaches and the use of seclusion/restraint in one acute mental health ward. This study was guided by Integrated Knowledge Translation (IKT) and informed by the Behaviour Change Wheel (BCW) approach. Implementation strategies were co-designed and included provision of sensory materials/resources; education/training; prompts/reminders; modelling; audit and feedback; workplace coalition; and facilitation. Data were collected through pre- and post-project questionnaires (pre- n = 37, post- n = 40) and routine clinical data. Data were analysed using SPSS and thematic analysis. Data for matched pairs (n = 19) revealed significant improvements between pre- and post-perceived levels of knowledge and confidence in using sensory approaches. Significant increases were found in the use of sensory kits, weighted modalities and sensory assessment/plans. Post participants' recommendations to sustain the use of sensory approaches in their unit included ongoing training; funding; maintenance and supply of sensory equipment; increased staffing; and support from colleagues. This is the first study to use the IKT and BCW to design, facilitate and evaluate a co-designed, theory-informed implementation strategy to improve the use of sensory approaches in an acute mental health unit.

Streamlining COM-B model: Insights from the Healthy Eating Context.

The global rise in diet-related diseases highlights the urgent need for effective behavioural interventions. While theoretical frameworks like the Capability, Opportunity, Motivation-Behaviour (COM-B) model are valuable for understanding and influencing healthy eating behaviours, their practical application is often hindered by complexity and extensive measurement demands. This study addresses these challenges by testing a simplified version of the COM-B model, focusing on a select set of items representing seven core constructs. We conducted a cross-sectional survey with 347 Australian young adults to validate this streamlined model, making it more accessible for researchers and practitioners. Our findings underscore the importance of automatic motivation, the physical environment, and physical capability as critical factors in promoting healthy eating behaviours. By simplifying the COM-B model, this research contributes to developing more practical and effective strategies for healthier eating, addressing a critical public health issue.

An Internationally Derived Process of Healthcare Professionals' Proactive Deprescribing Steps and Constituent Activities.

Proactive deprescribing is the process of tapering or stopping a medicine before harm occurs. This study aimed to specify and validate, with an international sample of healthcare professionals, a proactive deprescribing process of steps and constituent activities. We developed a proactive deprescribing process framework of steps which we populated with literature-derived activities required to be undertaken by healthcare professionals. We distributed a survey to healthcare professionals internationally, requesting for each activity the frequency of its occurrence in practice and whether it was important. Extended response questions investigated barriers and enablers to deprescribing. The 263 survey respondents were from 25 countries. A proactive deprescribing process was developed comprising four steps: (1) identify a patient for potential stop of a medicine, (2) evaluate a patient for potential stop of a medicine, (3) stop a medicine(s), and (4) monitor after a medicine has been stopped, and 17 activities. All activities were considered important by ≥70% of respondents. Nine activities required healthcare professionals to undertake in direct partnership with the patient and/or caregiver, of which seven were only sometimes undertaken. Deprescribing interventions should include a focus on addressing the barriers and enablers of healthcare professionals undertaking the activities that require direct partnership with the patient and/or caregiver.

Supporting General Practitioners and people with hypertension to maximise medication use to control blood pressure: the contribution of Collective Intelligence to the development of the 'Maximising Adherence, Minimising Inertia' (MIAMI) intervention.

Background: Hypertension remains one of the most important modifiable risk factors for stroke and heart disease. Anti-hypertensive medications are effective, but are often not used to maximum benefit. Sub-optimal dosing by prescribers and challenges with medication-taking for patients remain barriers to effective blood pressure control. Objectives: We aimed to systematically develop a theory-based complex intervention to support General Practitioners (GPs) and people with hypertension to maximise medication use to control blood pressure. Methods: We used the three-phase Behaviour Change Wheel (BCW) as the overarching intervention development framework. Collective Intelligence methodology was used to operationalise the stakeholder input to Phases 2 and 3 of the BCW. This took the form of a Collective Intelligence workshop with 19 stakeholders from diverse backgrounds including lived experience, general practice, nursing, pharmacy and health psychology. Techniques such as barrier identification, idea-writing and scenario-based design were used to generate possible intervention options. Intervention options were then selected and refined using the Acceptability, Practicability, Effectiveness, Affordability, Side-effects and Equity (APEASE) criteria and guidance from the MIAMI Public and Patient Involvement Panel. Results: The finalised MIAMI intervention consists of both GP and patient supports. GP supports include a 30-minute online training, information booklet and consultation guide (drop-down menu) embedded within the patient electronic health system. Patient supports include a pre-consultation plan, website, and a structured GP consultation with results from an Ambulatory Blood Pressure Monitor and urine chemical adherence test. The intervention components have been mapped to the intervention functions of the BCW and Behaviour Change Technique Ontology. Conclusion: Collective Intelligence offered a novel method to operationalise stakeholder input to Phases 2 and 3 of the BCW. The MIAMI intervention is now at pilot evaluation stage.

Beyond ideals: why the (medical) AI industry needs to motivate behavioural change in line with fairness and transparency values, and how it can do it.

Artificial intelligence (AI) is increasingly relied upon by clinicians for making diagnostic and treatment decisions, playing an important role in imaging, diagnosis, risk analysis, lifestyle monitoring, and health information management. While research has identified biases in healthcare AI systems and proposed technical solutions to address these, we argue that effective solutions require human engagement. Furthermore, there is a lack of research on how to motivate the adoption of these solutions and promote investment in designing AI systems that align with values such as transparency and fairness from the outset. Drawing on insights from psychological theories, we assert the need to understand the values that underlie decisions made by individuals involved in creating and deploying AI systems. We describe how this understanding can be leveraged to increase engagement with de-biasing and fairness-enhancing practices within the AI healthcare industry, ultimately leading to sustained behavioral change via autonomy-supportive communication strategies rooted in motivational and social psychology theories. In developing these pathways to engagement, we consider the norms and needs that govern the AI healthcare domain, and we evaluate incentives for maintaining the status quo against economic, legal, and social incentives for behavior change in line with transparency and fairness values.

Factors Influencing the Translation of Evidence Into Clinical Practice for Hospital Allied Health Professionals in Terms of the Domains of Behaviour Change Theory: A Systematic Review.

This systematic review provides an overview of the unique challenges allied health professions face in the translation and implementation of evidence into practice, which remain relatively under reported and uninformed by a theoretical basis of behaviour change. MEDLINE, EMBASE, CINAHL and Scopus databases from 2010 to 2022 were searched for primary study designs resulting in 21 articles included in this review (PROSPERO: 2022 CRD42022314996). Allied health disciplines reported in the review were mainly from occupational therapy, physiotherapy, dietetics, and speech pathology. The most frequently reported implementation determinants across the Theoretical Domains Framework were identified as 'environmental context and resources', and 'knowledge'. The results also identified a greater influence of 'social influences' and 'beliefs about consequences' in implementation. Implementing evidence into clinical practice is a multifaceted, complex process, and the use of the Theoretical Domains Framework provided a systematic approach to understanding the drivers behind the target behaviours. However, there is a paucity of studies across the allied health professions that describe implementation strategies used and their impact. Many of the studies focused on implementation by the individual clinician rather than the role organizations can play in the translation of evidence into practice.

Co-designing a vaping cessation program for Australian young adults: A conceptual model.

INTRODUCTION: Australian young adults (YA) report difficulties in quitting vaping. This study sought to understand what a vaping cessation program should look like from the perspective of current and former vapers, and professionals/experts involved in this health space, to inform the development of a conceptual model. METHODS: Data collection was informed by Social Cognitive Theory using co-design methodology to explore vaping cessation. Interactive workshops and semi-structured interviews were held online between March 2023-January 2024, with data from participants' narratives and written materials thematically analysed. RESULTS: YAs (18-24 years) identifying as current or former vapers (n=15) and health professionals/experts'(n=13) insights informed the model framework, incorporating three main elements based on environmental, personal and behavioural factors shaping vaping cessation. Four design considerations were identified; the program needs to be affordable, accessible, appropriate and adaptable. YAs expressed a strong preference to share their quitting journey with peers, endorsing a digital forum providing a hybrid framework of support. CONCLUSIONS: Vaping cessation is nuanced and complex requiring a multi-faceted approach targeted to the specific needs of the young adult population. IMPLICATIONS: The findings can be used to inform the development of a vaping cessation program tailored to young adults in Australia and other similar contexts. Young adults perceived sharing the quitting journey and being inspired by the lived experience of others as critical components for successful vaping cessation. Social Cognitive Theory is demonstrated to be a valuable behaviour change framework for understanding vaping cessation and should be considered in future research of intervention development.

Online public health promotion at the local level: An evaluation of four local authority-led marketing campaigns.

Objective: Local authority-led online campaigns offer the possibility of targeted health promotion to connect local services and residents. This study assesses the evidence for medium (e.g., click-trhoughs) and high (off-line behaviour change) levels of public engagement with four local authority-led campaigns across a variety of public health promotions (sexual health, weight loss, and vaccination), online marketing approaches (social media marketing, search engine marketing, and programmatic marketing) and target demographics (language, gender, age, income, ethnicity) undertaken by a London borough local authority. Methods: Employing quasi-experimental and observational study designs, engagement with local health services during the course of the campaigns was evaluated. The first three campaigns were evaluated based on an interrupted time series model of intervention assessment comparing outcome variables of interest during the campaign to periods before and after the campaign period. The results of the fourth campaign, an observational case-study, are discussed using descriptive statistics only. Results: The analyses of the high engagement data for two of the three campaigns statistically assessed clearly supported the effectiveness of the campaigns. While the effect of high engagement could not be determined in the other two campaigns, they provide data that may be useful in online campaign design. Conclusions: The evidence assessed in this study across a variety of platforms, health promotion initiatives, and population targets suggests that local authority-led online marketing campaigns for health promotion may be useful for increasing participation in public health programmes.

The Live Well intervention: Promoting healthy lifestyles during routine older people's mental healthcare.

OBJECTIVE: Lifestyle is an important determinant of health. The Live Well intervention allows mental health clinicians to address lifestyle during routine mental health encounters. METHOD: Clinicians were taught how to encourage consumers to learn more about lifestyle and health; consider their own lifestyle and health using a self-rated health and wellness questionnaire (HAWQ) and helped them decide which out of six health domains (physical, mental and social activity, healthy eating, mental wellbeing and positive thinking) should be improved in small, sustainable steps using a SMART (specific, measurable, achievable, relevant and timed) goal-setting template. RESULTS: Out of 65 enrolled consumers, 52 completed pre-intervention, 6-week and 12-week post-assessment assessments. There were improvements in all self-rated health domains except for heathy eating. At 12-week, consumers also recorded significant satisfaction with the Live Well program, goal achievement and wellbeing. Clinicians' feedback was positive about using this intervention with their consumers. CONCLUSIONS: Live Well is a feasible and effective way to engage consumers on positive lifestyle changes in routine mental health care encounters.

Co-designing planning interventions to facilitate participation in mail-out bowel cancer screening.

BACKGROUND: Population mail-out bowel cancer screening programs save lives through prevention and early detection; however, their effectiveness is constrained by low participation rates. Many non-participants are "intenders"; that is, they intend to screen but fail to do so, often forgetting or procrastinating. This study aimed to co-design interventions to increase screening participation among intenders in the Australian National Bowel Cancer Screening Program. METHODS: Three semi-structured interviews, and one online cross-sectional survey, were conducted between August 2021 and December 2022. Interviews with people who had completed and returned their latest screening kit ("completers") were first conducted to identify the planning strategies they had used. Using survey data, logistic regressions were conducted to analyse strategies predictive of participants having returned their latest bowel cancer screening kit. Then, intenders were interviewed to explore their opinions of these strategies and worked with researchers to adapt these strategies into prototype interventions to facilitate screening participation. All interviews were analysed using the framework approach of codebook thematic analysis. RESULTS: Interview participants who returned their kit shared their effective planning strategies, such as putting the kit in a visible place or by the toilet, planning a time at home to complete the kit, and using reminders. Survey participants who reported using such strategies were more likely to have completed their screening kit compared to those who did not. Prototype interventions developed and endorsed by intenders included providing a prompt to place the kit or a sticker near the toilet as a reminder, a deadline for kit return, the option to sign up for reminders, and a bag to store the sample in the fridge. CONCLUSIONS: These novel, consumer-led interventions that are built upon the needs and experience of screening invitees provide potential solutions to improve participation in population bowel cancer screening.

Perceptions and expectations of an artificially intelligent physical activity digital assistant - A focus group study.

Artificially intelligent physical activity digital assistants that use the full spectrum of machine learning capabilities have not yet been developed and examined. This study aimed to explore potential users' perceptions and expectations of using such a digital assistant. Six 90-min online focus group meetings (n = 45 adults) were conducted. Meetings were recorded, transcribed and thematically analysed. Participants embraced the idea of a 'digital assistant' providing physical activity support. Participants indicated they would like to receive notifications from the digital assistant, but did not agree on the number, timing, tone and content of notifications. Likewise, they indicated that the digital assistant's personality and appearance should be customisable. Participants understood the need to provide information to the digital assistant to allow for personalisation, but varied greatly in the extent of information that they were willing to provide. Privacy issues aside, participants embraced the idea of using artificial intelligence or machine learning in return for a more functional and personal digital assistant. In sum, participants were ready for an artificially intelligent physical activity digital assistant but emphasised a need to personalise or customise nearly every feature of the application. This poses challenges in terms of cost and complexity of developing the application.

Facilitators and barriers of technology adoption and social connectedness among rural older adults: a qualitative study.

Background: Social disconnection is a public health concern among rural Australian older adults. While research suggests technology can enhance social wellbeing and protect against social disconnection, many older adults are not digitally literate, and little is known as to why and how technology adoption could be promoted in rural contexts. This study aimed to (1) explore the barriers and facilitators of technology adoption among rural older adults and (2) determine the potential utility of technology to promote social connectedness in the aged population. The Theoretical Domains Framework and the Behaviour Change Wheel (BCW) were employed to gain a comprehensive understanding of the digital and social behaviours of rural Australian older adults. Methods: Semi-structured interviews were conducted with a convenience sample of 33 rural older adults aged between 65 and 87 years. Interviews were conducted over the phone, audio-recorded, and transcribed. Interview transcripts were coded and analysed using thematic analysis and the BCW. Results: Numerous barriers and facilitators of technology adoption were identified, with the most prominent being knowledge, perceived value, perceived self-efficacy, and social support. Findings suggest that older adults' technology adoption is not simply a technical matter, but influenced by various individual, social, and environmental contexts. Consideration of these factors during development, marketing, training and implementation may facilitate technology adoption among older adults. With regard to social connectedness, several rural barriers emerged, including low population density, geographic isolation, limited community opportunities and poor public transport infrastructure. Conclusion: Technology was consistently identified as a facilitator of the social experience, indicating that technology is a promising tool to enhance social connectedness among older adults, particularly those living in rural areas. Future research should focus on enhancing the capability, opportunity and motivation of older adults in technology adoption, with reference to the rural contexts.

Using Normalisation Process Theory to explore the contribution of stakeholder workshops to the development and refinement of a complex behavioural intervention: the STAMINA lifestyle intervention.

BACKGROUND: The National Institute for Health and Care Excellence (NICE) recommend that men with prostate cancer on androgen deprivation therapy (ADT) are offered twice weekly supervised aerobic and resistance exercise to address side effects of treatment. However, supervised exercise is not routinely offered in standard clinical practice. The STAMINA programme grant for applied research (PGfAR) has been designed to evaluate whether this recommendation can be delivered within standard NHS care. This paper describes how future implementation of NICE recommendations within the NHS was explored during complex intervention development to enable evaluation of a lifestyle intervention. METHODS: Two stakeholder workshops were conducted to explore factors pertinent to future implementation of the STAMINA Lifestyle intervention (SLI). Normalisation Process Theory (NPT) provided the theoretical framework for discussion and analysis. Stakeholder workshop 1 focussed on intervention coherence and buy-in. Stakeholder workshop 2 explored barriers and facilitators for embedding SLI into the context of the NHS, with delivery partner Nuffield Health, in the future. RESULTS: Workshops were attended by healthcare professionals (n = 16), exercise professionals (n = 17), members of public involved in PPI including patients (n = 12), health psychologists (n = 2), clinical commissioners (n = 4), cancer charities (n = 3), a cancer alliance (n = 1) and health economist (n = 1). Stakeholders agreed that professional training packages should emphasise the uniqueness of the SLI and underpinning theory and evidence (Coherence). To further engagement, the use of STAMINA champions and information about the delivery partner were recommended to enhance confidence and knowledge (Cognitive participation). Furthermore, a simple communication (Collective Action) and progress reporting system (Reflexive Monitoring) was suggested to fit into existing infrastructure within the NHS and community partner. CONCLUSIONS: Application of NPT within two stakeholder workshops enhanced complex intervention development. Context-specific strategies to support implementation of SLI within the context of a trial were proposed, sensed-checked, and considered acceptable. The organisational implications of embedding and sustaining the intervention in preparation for wider NHS roll-out were considered (if proven to be effective) and will be explored in the qualitative component of a process evaluation underpinned by NPT.

Adults' beliefs related to reducing red meat consumption: An exploratory study in the province of Quebec, Canada.

A significant consumption of red meat is associated with various issues (e.g. public health, sustainability, animal welfare). This exploratory study aims to identify the perceived advantages and disadvantages, perceived approval and disapproval by important others, and perceived barriers and facilitators pertaining to reducing red meat consumption among adults. An online questionnaire based on the Theory of Planned Behaviour was used to elicit the salient beliefs of 55 red meat eaters living in the province of Quebec (Canada). A content analysis performed by two independent coders revealed that the predominant themes (modal beliefs) included health, environment, saving money, food preferences, social influence, perceptions of the alternatives of meat, and efforts related to change. This study can inform the development of interventions aimed at promoting the reduction of red meat consumption.

The frail-LESS (LEss sitting and sarcopenia in frail older adults) remote intervention to improve sarcopenia and maintain independent living via reductions in sedentary behaviour: findings from a randomised controlled feasibility trial.

BACKGROUND: Sarcopenia leads to functional disability, dependence in activities of daily living (ADL), and is a key contributor to frailty. Reducing and breaking up sedentary time is associated with improved sarcopenia and frailty-related outcomes. The aim of this study was to determine the feasibility of delivering and evaluating a remote sedentary behaviour intervention to improve sarcopenia and independent living in older adults with frailty. METHODS: A two-arm randomised controlled feasibility trial was conducted with a target of 60 older adults (mean age 74 ± 6 years) with very mild or mild frailty. Participants were randomised to the Frail-LESS (LEss Sitting and Sarcopenia in Frail older adults) intervention or usual care control group for six months. The intervention included tailored feedback on sitting, standing and stepping; an education workbook that included goal setting and action planning; one-to-one health coaching; peer support; and a wearable device to self-monitor sedentary behaviour. Participant recruitment (percentage of eligible individuals recruited), retention and data completion rates were used to assess trial feasibility. Acceptability of the trial was explored through interviews and safety was evaluated via unplanned healthcare utilisation and number of falls. Sitting, standing, stepping and sarcopenia were measured to evaluate potential intervention effects. RESULTS: Sixty participants were recruited. Recruitment and retention rates were 72% and 83%, respectively. Completion rates for outcome measures ranged from 70 to 100%. The trial was safe (< 1 fall per participant on average at each timepoint) and trial procedures were acceptable. Descriptive analysis (mean ± SD) showed that daily sitting was 25.1 ± 82.1 min/day lower in the intervention group, and 6.4 ± 60.5 min/day higher in the control group, at 6 months compared with baseline. Hand grip strength and sit-to-stand score were improved by 1.3 ± 2.4 kg and 0.7 ± 1.0, respectively, in the intervention group. CONCLUSIONS: This study demonstrates the feasibility and safety of delivering and evaluating a remote intervention to reduce and break up sitting in older adults with frailty. The intervention showed evidence towards reducing daily sitting and improving sarcopenia, supporting its evaluation in a definitive randomised controlled trial. TRIAL REGISTRATION: ISRCTN registry (registration number: ISRCTN17158017). Registered 6th August 2021.

Behaviour change intervention (education and text) to prevent dental caries in secondary school pupils: BRIGHT RCT, process and economic evaluation.

Background: The presence of dental caries impacts on children's daily lives, particularly among those living in deprived areas. There are successful interventions across the United Kingdom for young children based on toothbrushing with fluoride toothpaste. However, evidence is lacking for oral health improvement programmes in secondary-school pupils to reduce dental caries and its sequelae. Objectives: To determine the clinical and cost effectiveness of a behaviour change intervention promoting toothbrushing for preventing dental caries in secondary-school pupils. Design: A multicentre, school-based, assessor-blinded, two-arm cluster randomised controlled trial with an internal pilot and embedded health economic and process evaluations. Setting: Secondary schools in Scotland, England and Wales with above-average proportion of pupils eligible for free school meals. Randomisation occurred within schools (year-group level), using block randomisation stratified by school. Participants: Pupils aged 11-13 years at recruitment, who have their own mobile telephone. Interventions: Two-component intervention based on behaviour change theory: (1) 50-minute lesson delivered by teachers, and (2) twice-daily text messages to pupils' mobile phones about toothbrushing, compared with routine education. Main outcome measures: Primary outcome: presence of at least one treated or untreated carious lesion using DICDAS4-6MFT (Decayed, Missing and Filled Teeth) in any permanent tooth, measured at pupil level at 2.5 years. Secondary outcomes included: number of DICDAS4-6MFT; presence and number of DICDAS1-6MFT; plaque; bleeding; twice-daily toothbrushing; health-related quality of life (Child Health Utility 9D); and oral health-related quality of life (Caries Impacts and Experiences Questionnaire for Children). Results: Four thousand six hundred and eighty pupils (intervention, n = 2262; control, n = 2418) from 42 schools were randomised. The primary analysis on 2383 pupils (50.9%; intervention 1153, 51.0%; control 1230, 50.9%) with valid data at baseline and 2.5 years found 44.6% in the intervention group and 43.0% in control had obvious decay experience in at least one permanent tooth. There was no evidence of a difference (odds ratio 1.04, 95% confidence interval 0.85 to 1.26, p = 0.72) and no statistically significant differences in secondary outcomes except for twice-daily toothbrushing at 6 months (odds ratio 1.30, 95% confidence interval 1.03 to 1.63, p = 0.03) and gingival bleeding score (borderline) at 2.5 years (geometric mean difference 0.92, 95% confidence interval 0.85 to 1.00, p = 0.05). The intervention had higher incremental mean costs (£1.02, 95% confidence interval -1.29 to 3.23) and lower incremental mean quality-adjusted life-years (-0.003, 95% confidence interval -0.009 to 0.002). The probability of the intervention being cost-effective was 7% at 2.5 years. However, in two subgroups, pilot trial schools and schools with higher proportions of pupils eligible for free school meals, there was an 84% and 60% chance of cost effectiveness, respectively, although their incremental costs and quality-adjusted life-years remained small and not statistically significant. The process evaluation revealed that the intervention was generally acceptable, although the implementation of text messages proved challenging. The COVID-19 pandemic hampered data collection. High rates of missing economic data mean findings should be interpreted with caution. Conclusions: Engagement with the intervention and evidence of 6-month change in toothbrushing behaviour was positive but did not translate into a reduction of caries. Future work should include work with secondary-school pupils to develop an understanding of the determinants of oral health behaviours, including toothbrushing and sugar consumption, particularly according to free school meal eligibility.

Tooth decay has an impact on children and young people's daily lives, particularly those living in deprived areas. For young children, programmes to improve toothbrushing with fluoride toothpaste help prevent tooth decay. The Brushing RemInder 4 Good oral HealTh trial (BRIGHT) investigated whether a secondary-school-based toothbrushing programme would work. We developed a new programme which included a lesson and twice-daily text messages sent to pupils' phones. In total, 4680 pupils, aged 11­13 years, from 42 secondary schools in the United Kingdom took part in the trial. At each school, one year group was randomly selected to receive the programme, while the other year group did not receive it. All pupils were followed up for 2.5 years to see whether there were any differences in levels of tooth decay, frequency of toothbrushing, plaque or quality of life. We also considered the programme's value for money and the views of pupils and school staff. We followed up 2383 pupils and found no difference in tooth decay, plaque or quality of life. We found those who had the programme were more likely to brush their teeth twice daily after 6 months than those who did not. The programme was not good value for money overall. However, the programme appeared to be of more benefit at preventing tooth decay in pupils eligible for free school meals compared to those not eligible. In the schools with more pupils eligible for free school meals, the chance of the programme representing good value for money increased. The programme was generally liked by the pupils and school staff. Some pupils found the text messages useful, although others said they were annoying. The programme helped pupils brush their teeth more frequently in the short term, but this did not lead to less tooth decay. Further research is needed to understand how to prevent tooth decay in secondary-school pupils.

Road to referral success in COPD: Enhancing patient engagement through dedicated conversations about pulmonary rehabilitation programs.

RESEARCH QUESTION: From the perspectives of healthcare professionals (HCPs) and people with chronic obstructive pulmonary disease (COPD) known to tertiary care, what influences successful referrals to a pulmonary rehabilitation program (PRP)? METHODS: This cross-sectional qualitative study was informed by a critical realist perspective. We purposively sampled people with COPD and HCPs who deliver COPD care and used semi-structured interviews and focus groups to explore determinants of a successful referral to a PRP. Interviews were recorded, transcribed verbatim and analysed using reflexive thematic analysis. RESULTS: Data were available on 38 HCPs and 15 people with COPD. We generated three core themes pertaining to successful referrals. The first theme was that HCPs should be mindful of how professional responsibilities (such as their personal value and interest in a PRP, their degree of understanding of PRPs, and the organisational culture the PRPs are embedded within) shape decision-making during a therapeutic interaction. The second theme, there's more to me than my COPD, characterised psychological perceptions that shape a person's readiness to engage in a PRP. The third theme, communication is a two-way street that requires careful navigation, characterised the interpersonal dynamic between HCP and patient, and how dedicated conversations about PRPs can encourage successful referrals. CONCLUSION: Therapeutic interactions that include dedicated conversations about PRPs can foster successful referrals among people with COPD. During these interactions, HCPs should take the time to understand and carefully unpack psychological perceptions whilst imparting value, interest and enthusiasm for PRPs. Doing so can shape patient engagement toward referral success.

Evaluating the Let's Move It intervention programme theory for adolescents' physical activity: Theorized psychosocial mechanisms of behavioural changes.

OBJECTIVES: Behaviour change theories have extensively been used in health behaviour change interventions and their programme theories. However, they are rarely evaluated in randomized field studies. The Let's Move It intervention targeted various psychosocial constructs to increase adolescents' physical activity. A theory-based process evaluation aiming to illuminate the trial findings as well as to test the programme theory used is conducted. Specifically, we investigate whether the intervention influenced the theorized determinants of change immediately post-intervention and after 1 year, and whether these determinants were associated with changes in physical activity. DESIGN: A cluster-randomized controlled trial (n = 1166). METHODS: We measured theorized determinants with self-report, and physical activity (PA) with accelerometry and self-report. The effects are evaluated with repeated measures ANOVA and regression models. RESULTS: No changes were detected in most theorized determinants but intervention arm reported higher enactment of behaviour change techniques used during intervention immediately post-intervention and lower descriptive norms for PA throughout. Autonomous motivation was associated with PA immediately post-intervention. CONCLUSIONS: The lack of intervention effects may be due to many factors, for example insensitive measures, ceiling effects. However, reporting these null effects advances understanding of behaviour change processes. We introduce methodologic possibilities for future intervention programme theory evaluation efforts.
