A systematic review of behaviour change techniques used in interventions to increase physical activity among breast cancer survivors

Background Despite evidence that physical activity (PA) can help reduce recurrence and mortality, many breast cancer survivors are less active than recommended levels. The aim of this systematic review is to advance our understanding of which behaviour change techniques (BCTs) have been used in interventions promoting breast cancer survivors’ PA and to evaluate their potential to increase PA. Methods A systematic search was conducted in five databases (Medline; PsycInfo; Embase; CINAHL and Scopus) for studies published between 2005 and 2019. Following a rigorous screening process, 27 studies were retained. These were reviewed and analysed for quality, coded for BCTs (k = 0.65) and interventions categorised according to their potential to increase PA using an established methodology. Results The majority of studies were moderate quality (64%). Demonstration on how to perform the behaviour was the most commonly used BCT (n = 23). Adding objects to the environment, (pedometer or accelerometer) was the BCT with the highest potential to increase PA. This was followed by, goal setting and self-monitoring of behaviour. A theory-based approach to evaluation was used in only 59% (n = 16) of the studies. Conclusions The results of this review inform which BCTs have the potential to increase PA for breast cancer survivors and inform intervention development. Future research, is encouraged to properly report intervention procedures around dose and frequency of intervention components to allow for review and replication.

Behaviour Change Techniques in Weight Gain Prevention Interventions in Adults of Reproductive Age: Meta-Analysis and Meta-Regression

Weight gain prevention interventions are likely to be more effective with the inclusion of behaviour change techniques. However, evidence on which behaviour change techniques (BCT) are most effective for preventing weight gain and improving lifestyle (diet and physical activity) is limited, especially in reproductive-aged adults. This meta-analysis and meta-regression aimed to identify BCT associated with changes in weight, energy intake and physical activity in reproductive-aged adults. BCT were identified using the BCT Taxonomy (v1) from each intervention. Meta-regression analyses were used to identify BCT associated with change in weight, energy intake and physical activity. Thirty-four articles were included with twenty-nine articles for the meta-analysis. Forty-three of the ninety-three possible BCT listed in the taxonomy were identified in the included studies. Feedback on behaviour and Graded tasks were significantly associated with less weight gain, and Review behaviour goals was significantly associated with lower energy intake. No individual BCT were significantly associated with physical activity. Our analysis provides further evidence for which BCT are most effective in weight gain prevention interventions. The findings support that the use of key BCT within interventions can contribute to successful weight gain prevention in adults of reproductive age.

Using Insights from Behavioural Science and Design Thinking to Develop mHealth Interventions: a Systematic Scoping Review (Preprint)

BACKGROUND Mobile health (mHealth) interventions are increasingly being designed to facilitate health-related behaviour change. Integrating insights from behavioural science and design science can help support the development of more effective mHealth interventions. Behavioural Design (BD) and Design Thinking (DT) have emerged as best practice approaches in their respective fields. Until now, little work has been done to examine how BD and DT can be integrated throughout the mHealth design process. OBJECTIVE The aim of this scoping review was to map the evidence on how insights from BD and DT can be integrated to guide the design of mHealth interventions. The following questions were addressed: (1) what are the main characteristics of studies that integrate BD and DT during the mHealth design process? (2) what approaches do mHealth design teams use to integrate BD and DT during the mHealth design process? (3) what are key implementation considerations, design challenges, and future directions for integrating BD and DT during mHealth design? METHODS We identified relevant studies from MEDLINE, PSYCINFO, EMBASE, CINAHL and JMIR using search terms related to mHealth, behavioural design, and design thinking. Included articles had to clearly describe their mHealth design process and how behaviour change theories, models, frameworks, or techniques were incorporated. Two independent reviewers screened articles for inclusion and completed the data extraction. A descriptive analysis was conducted. RESULTS A total of 75 articles met the inclusion criteria. All studies were published between 2012 and 2021. Studies integrated BD and DT in notable ways, which we refer to as “Behavioural Design Thinking”. Five steps were followed in the “Behavioural Design Thinking” approach: (1) empathise with users and their behaviour change needs, (2) define user and behaviour change requirements, (3) ideate user-centred features and behaviour change content, (4) prototype a user-centred solution that supports behaviour change, (5) test the solution against users’ needs and for its behaviour change potential. Key challenges experienced during mHealth design included meaningfully engaging patient and public partners in the design process, translating evidence-based behaviour change techniques into actual mHealth features, and planning for how to integrate the mHealth intervention into existing clinical systems. Guidance is needed on how to conduct the design process itself, how to meaningfully engage key stakeholders, and how to operationalize behaviour change techniques in a user-friendly and context-specific way. CONCLUSIONS Best practices from BD and DT can be integrated throughout the mHealth design process to ensure that mHealth interventions are purposefully developed to effectively engage users. Although this scoping review clarified how insights from BD and DT could be integrated during mHealth design, future research is needed to identify the most effective design approaches.

Moving from intention to behaviour: a randomised controlled trial protocol for an app-based physical activity intervention (i2be)

IntroductionEfficacy tests of physical activity interventions indicate that many have limited or short-term efficacy, principally because they do not sufficiently build on theory-based processes that determine behaviour. The current study aims to address this limitation.Methods and analysisThe efficacy of the 8-week intervention will be tested using a three-condition randomised controlled trial delivered through an app, in women with a prior hypertensive pregnancy disorder. The intervention is based on the integrated behaviour change model, which outlines the motivational, volitional and automatic processes that lead to physical activity. The mechanisms by which the behaviour change techniques lead to physical activity will be tested.Following stratification on baseline factors, participants will be randomly allocated in-app to one of three conditions (1:1:1). The information condition will receive information, replicating usual care. Additionally to what the information condition receives, the motivation condition will receive content targeting motivational processes. Additionally to what the motivation condition receives, the action condition will receive content targeting volitional and automatic processes.The primary outcome is weekly minutes of moderate-to-vigorous physical activity, as measured by an activity tracker (Fitbit Inspire 2). Secondary outcomes include weekly average of Fitbit-measured daily resting heart rate, and self-reported body mass index, waist-hip ratio, cardiorespiratory fitness and subjective well-being. Tertiary outcomes include self-reported variables representing motivational, volitional, and automatic processes. Outcome measures will be assessed at baseline, immediately post-intervention, and at 3 and 12 months post-intervention. Physical activity will also be investigated at intervention midpoint. Efficacy will be determined by available case analysis. A process evaluation will be performed based on programme fidelity and acceptability measures.Ethics and disseminationThe Medical Ethics Committee of the Erasmus MC has approved this study (MEC-2020-0981). Results will be published in peer reviewed scientific journals and presented at scientific conferences.Trial registration numberNetherlands trial register, NL9329.

Using the Behaviour Change Wheel to Design an App to Change Tourist Behaviour and Increase Dispersal into Regional Areas

Currently, many tourism destinations are experiencing greatly reduced tourism due to COVID-19. In order to ensure that regions that wish to engage in tourism can share the benefits of it more equally, and to prevent the predicted future problem of overuse of popular areas once pre-COVID visitor numbers resume, an app to encourage tourists and leisure-seekers to change their behaviour and disperse into regional areas has been developed. The Behaviour Change Wheel was used to define the problem, find suitable intervention functions and design methods of delivery that could increase tourists’ capability, opportunity and motivation to disperse farther into regions. The Huon Valley of Tasmania, Australia, was used as a research area. Our application of the Behaviour Change Wheel methodology determined that active engagement in logistic, value-based, and social information has the greatest chance of changing behaviour in this region and a list of Behaviour Change Techniques has been developed and considered in the design of a gamified travel app.

Nutrition Concepts for the Treatment of Obesity in Adults

Obesity caused by a positive energy balance is a serious health burden. Studies have shown that obesity is the major risk factor for many diseases like type 2 diabetes mellitus, coronary heart diseases, or various types of cancer. Therefore, the prevention and treatment of increased body weight are key. Different evidence-based treatment approaches considering weight history, body mass index (BMI) category, and co-morbidities are available: lifestyle intervention, formula diet, drugs, and bariatric surgery. For all treatment approaches, behaviour change techniques, reduction in energy intake, and increasing energy expenditure are required. Self-monitoring of diet and physical activity provides an effective behaviour change technique for weight management. Digital tools increase engagement rates for self-monitoring and have the potential to improve weight management. The objective of this narrative review is to summarize current available treatment approaches for obesity, to provide a selective overview of nutrition trends, and to give a scientific viewpoint for various nutrition concepts for weight loss.

A systematic review of the characteristics of interventions that promote physical activity in adults with asthma

Physical activity is promoted in the asthma population through pulmonary rehabilitation, but limited funding and facilities are available. This review aimed to examine the effectiveness of interventions that promote physical activity and identify the behaviour change techniques (BCTs) and other intervention components used. Five databases were searched, and 25 studies met the inclusion criteria. Interventions had a significant positive effect on physical activity, sedentary behaviour, quality of life and asthma symptoms. BCTs used across intervention and control groups were similar in studies that showed effects and those that did not. Future interventions should employ techniques that help to maintain behaviour change.

A Systematic Approach to Identifying and Developing Implementation Strategies to Support the Uptake of a Risk Tool to Aid in Clinical Management of Patients with Syncope: A Qualitative Study

Background: The Canadian Syncope Risk Score (CSRS) is a validated risk stratification tool developed to optimize the accuracy of emergency department decisions and inform evidence-based clinical actions. While preliminary work has been undertaken to understand the barriers to CSRS use, no work to date has explored how to implement the CSRS to overcome these barriers in practice. This study aimed to identify which implementation strategies are most appropriate to address these barriers and how they should be implemented to mitigate the possibility of poor uptake. Methods: We conducted a series of three iterative online user-centered design workshops with emergency medicine physicians from three hospital sites in Ontario, Canada. The objective of the workshops was to engage participants in identifying acceptable strategies to promote CSRS uptake and how they should be operationalized. To support this, we systematically mapped previously identified barriers to corresponding behaviour change techniques to identify the most likely strategies to effect change. The sessions were audio-recorded and dialogue relating directly to the study objective were transcribed. We performed a qualitative content data analysis according to pre-defined objectives for each workshop. Results: Fourteen physicians participated across the three workshops. The main implementation strategies identified to overcome identified barriers were: education in the format of meetings, videos, journal clubs, and posters (uncertainty around when and how to apply the CSRS); an online calculator and integration of the CSRS into electronic medical record (uncertainty in how to apply the CSRS), local champion (lack of team buy-in); and dissemination of evidence summaries and feedback through email communications (lack of evidence about impact). Conclusions: The ability of the CSRS to effectively improve patient safety and syncope management relies on broad buy-in and uptake across physicians. To ensure the CSRS is well-positioned for impact, a comprehensive suite of implementation strategies was identified to address known barriers. This next phase of work will provide insight into whether these strategies facilitated better alignment with barriers, higher physician engagement with the implementation strategies, and broader uptake of the CSRS, with the objective of improving the likelihood that the CSRS will positively influence patient outcomes.
