Interpersonal style should be included in taxonomies of behavior change techniques

Determinants, behaviour change techniques and pedagogical approaches used in secondary school-based food and nutrition programmes: a qualitative study of the SWITCH project

BACKGROUND

Food and nutrition programmes at secondary schools have the potential to improve public and planetary health, as they target a wide range of adolescents. Nevertheless, it is currently unclear what mechanisms are underlying such educational interventions in order to aim for behaviour change. This qualitative study therefore aims to identify determinants and behaviour change techniques (BCTs) incorporated in secondary school-based food and nutrition programmes. Better understanding of determinants and BCTs can identify points of improvements to facilitate long-term dietary behaviour change.

METHODS

Fifteen online semi-structured interviews were conducted between November 2021 and January 2022 with representatives of 14 Dutch programmes, supplemented by a document analysis of scientific and grey literature related to the included programmes (e.g., evaluation reports, teacher manuals). Transcripts and literature were analysed deductively, using the terminology of Mechanisms of Action (MOAs) and the BCT Taxonomy v1, followed by an inductive coding phase.

RESULTS

Determinants knowledge (n = 13), skills (n = 12), awareness (n = 9), and beliefs about consequences (n = 7) were identified most, as well as BCTs Knowledge transfer (n = 13), Natural consequences (n = 7) and Goals and planning (n = 5). Inductive coding led to the identification of pedagogical approaches that were considered important for successful delivery of programmes, such as the use of activating learning methods.

CONCLUSIONS

It seems promising for food and nutrition programmes at secondary schools to expand their current focus beyond knowledge and skills, to also target environmental, social and other essential individual determinants during adolescence which are now under-reported, such as identity. Moreover, our study revealed the importance for programmes to be tailored to adolescents' worldviews and to stimulate adolescents to be actively involved.

Protection motivation theory and health behaviour: conceptual review, discussion of limitations, and recommendations for best practice and future research

Protection motivation theory is a pre-eminent health behaviour theory purposed to predict participation in health protection and risk behaviours. It has been widely applied across multiple behaviours, populations and contexts. In this conceptual review, we summarise research applying the theory and identify shortcomings and evidence gaps that limit reported inferences and impede theory and intervention development. Accordingly, we provide recommendations for best practices and suggestions for future research to resolve these limitations. Limitations identified include a dearth of comprehensive theory tests, sparse evidence of theory sufficiency, a lack of studies including additional constructs, overuse of correlational and cross-sectional research designs, a paucity of intervention studies and tests of theory-consistent mechanisms of action, few tests intrapersonal and environmental moderators of theory effects and measurement concerns. We provide recommendations to address these limitations including conducting comprehensive theory tests in support of nomological validity; incorporating past behaviour and other constructs to establish theory sufficiency and extend its scope; adopting cross-lagged panel and factorial experimental research designs to test directional effects, permit better causal inference and test mechanisms of action; testing effects of moderators to identify conditions that may affect theory applicability and developing measurement standards for study constructs and adopting non-self-report behaviour measures.

Tele-health coaches' responses to clients' emotional cues and concerns and engagement with the Bump to Baby and Me Intervention

OBJECTIVE

To explore the relationship between health coaches' responses to emotional cues/concerns and women's subsequent engagement with the health coaching mHealth platform.

METHODS

24 face-to-face video-mediated initial conversations between participants and their health coaches were coded using the VR-CoDES-P method. Women with high risk of developing Gestational Diabetes Mellitus were selected from the study, based on their engagement with the smartphone health coaching platform. 12 women with very low engagement and 12 women with high engagement were identified.

RESULTS

In interactions with women with high goal engagement, coaches had significantly more counseling codes with prior other codes and no instances of non-explicit response codes that reduce space for further disclosure. Analysis showed that interactions with women with high goal engagement were more frequently met by the coach with affect-acknowledging and empathic responses prior to the counseling speech act.

CONCLUSION

High goal engagement among women with Gestational Diabetes Mellitus may appear to be associated with coaches facilitating the frequent use of empathy.

PRACTICE IMPLICATIONS

Findings can draw coaches' attention to the impact that their counseling has on goal engagement, increasing the opportunity for intervention to be person-centered and effective.

Specifying how intervention content is communicated: Development of a Style of Delivery Ontology

Background: Investigating and enhancing the effectiveness of behaviour change interventions requires detailed and consistent specification of all aspects of interventions. We need to understand not only their content, that is the specific techniques, but also the source, mode, schedule, and style in which this content is delivered. Delivery style refers to the manner by which content is communicated to intervention participants. This paper reports the development of an ontology for specifying the style of delivery of interventions that depend on communication. This forms part of the Behaviour Change Intervention Ontology, which aims to cover all aspects of behaviour change intervention scenarios. Methods: The Style of Delivery Ontology was developed following methods for ontology development used in the Human Behaviour-Change Project, with seven key steps: 1) defining the scope of the ontology, 2) identifying key entities and developing their preliminary definitions by reviewing 100 behaviour change intervention evaluation reports and existing classification systems, 3) refining the ontology by piloting the ontology through annotations of 100 reports, 4) stakeholder review by eight behavioural science and public health experts, 5) inter-rater reliability testing through annotating 100 reports using the ontology, 6) specifying ontological relationships between entities, and 7) disseminating and maintaining the ontology. Results: The resulting ontology is a five-level hierarchical structure comprising 145 unique entities relevant to style of delivery. Key areas include communication processes, communication styles, and attributes of objects used in communication processes. Inter-rater reliability for annotating intervention evaluation reports was α=0.77 (good) for those familiar with the ontology and α=0.62 (acceptable) for those unfamiliar with it. Conclusions: The Style of Delivery Ontology can be used for both annotating and describing behaviour change interventions in a consistent and coherent manner, thereby improving evidence comparison, synthesis, replication, and implementation of effective interventions.

Time to move beyond monological perspectives in health behavior change communication research and practice

Chronic disease self-management and health behavior change programs are becoming increasingly important to health service delivery to prevent the development of chronic disease and optimize health outcomes for those who suffer from it. To train people to deliver these programs effectively, we need to understand both the what and how of program delivery. While there is an abundant literature on what, and a merging evidence about what techniques to use, such as goals setting and self-monitoring, the literature on how programs should be delivered is less well developed. This paper reviews emerging research in this area and identifies an underlying monological approach. We argue that this currently dominant model cannot address the key issues in this area. By considering the theoretical framework of Dialogism, we introduce the method of Conversation Analysis to the field of behavior change interventions. Extensive research into health communication has endeavored to show the importance of language and the organization of interactions. We demonstrate and discuss how a monological approach to interventions prevents exploration of what professionals do to deliver intervention content. In doing so, we show that techniques do not account for how successfully an intervention is delivered.

Understanding dietary behaviour change after a diagnosis of diabetes: A qualitative investigation of adults with type 2 diabetes

Type 2 diabetes (T2D) is a major public health concern. Optimal management of T2D often requires individuals to make substantial changes to their dietary intake. This research employed a qualitative methodology to examine decision making processes underpinning dietary behaviour change. Semi-structured telephone interviews were conducted on a purposive sample of 21 Australian adults who had recently consulted a dietitian after being diagnosed with T2D. Data were analysed using theoretical thematic analysis and themes were matched deductively with constructs that underpin motivational, volitional, and implicit processes which exist in common models of behaviour change. Influences on motivation, such as a desire to improve health status and making use of valuable support networks featured in participant narratives. Volitional influences included knowing their limits, dealing with falling off the wagon, and learning how their body responds to food. The themes unlearning habits and limit the availability were identified as underpinning implicit influences on dietary change. Individual differences and emotions were constructs additional to the model that influenced dietary change. These findings contribute to a richer understanding of the subjective experiences of adults with T2D regarding dietary change and highlight the multiple processes that guide their decision making in this context.

Factors influencing adults who participate in a physical activity coaching intervention: a theoretically informed qualitative study

OBJECTIVE

Behaviour change interventions targeting changes in physical activity (PA) can benefit by examining the underlying mechanisms that promote change. This study explored the use of the Capability, Opportunity, Motivation and Behaviour (COM-B) model and the Theoretical Domains Framework (TDF) to code and contextualise the experiences of participants who completed a PA coaching intervention underpinned by motivational interviewing and cognitive-behavioural therapy.

DESIGN

Semistructured interviews were conducted with a purposive sample of participants.

SETTING

Interviews were conducted in a tertiary hospital in regional Victoria, Australia.

PARTICIPANTS

Eighteen participants who completed a PA coaching intervention were interviewed. The participants were recruited into the coaching intervention because they were insufficiently physically active at the time of recruitment.

RESULTS

Thirteen (72%) participants were women and the average age of participants was 54 (±5) years. Four participant themes mapped directly onto five components of the COM-B model, and ten of the TDF domains. Increases in PA were influenced by changes in motivation and psychological capability. The autonomy-supportive PA coaching intervention helped to evoke participants' own reasons (and motives) for change and influenced PA behaviours. Participants reflected on their own social and/or professional strengths, and used these skills to set appropriate PA goals and action plans. The structure of the PA coaching intervention provided clarity on session determinants and a framework from which to set an appropriate agenda. Relational components (eg, non-judgemental listening, collaboration) were continually highlighted as influential for change, and should be considered in future behaviour change intervention design.

CONCLUSIONS

We demonstrate the beneficial effect of using theory-informed behaviour change techniques, and delivering them in a style that promotes autonomy and relatedness. The views of participants should be a key consideration in the design and implementation of PA coaching interventions TRIAL REGISTRATION NUMBER: ACTRN12619000036112. Post-results analysis.

Understanding rural-living young adult cancer survivors' motivation during a telehealth behavior change intervention within a single-arm feasibility trial

A single-arm feasibility trial was conducted to explore rural-living young adult cancer survivors' physical activity, fruit and vegetable consumption, and motivational processes underlying any behavior changes during a telehealth behavior change intervention grounded in self-determination theory. Participants (n = 7; 85.7% female; Mage = 33.9, range = 28-37) met with a health coach once a week for 60 min for 12 weeks. Participants completed pre- and post-intervention surveys that assessed their behaviors, basic psychological needs satisfaction, and behavioral regulations. Participants also completed a semi-structured interview post-intervention. Quantitative results indicate behavioral outcomes, basic psychological needs satisfaction, and behavioral regulations increased from pre- to post-intervention. Five themes provide context for the observed increases. Results provide preliminary evidence that motivation for physical activity and fruit and vegetable consumption may be facilitated by a one-on-one telehealth intervention among rural-living young adult cancer survivors. Large scale studies are needed to determine effectiveness of the intervention and identify mechanisms underpinning behavioral outcomes.

Women's Preferences for Body Image Programming: A Qualitative Study to Inform Future Programs Targeting Women Diagnosed With Breast Cancer

Purpose: This paper describes women's opinions of the attributes of the ideal body image program to inform the design, development, and implementation of future programs for those diagnosed with breast cancer. Methods: Deductive-inductive content analysis of semi-structured interviews with 26 women diagnosed with breast cancer (mean age = 55.96 years; mean time since diagnosis = 2.79 years) was performed. Findings: Participants' opinions regarding the ideal body image program are summarized into five themes, mapping the where (community-based, hospital-based, or online), when (across the cancer continuum or at specific points), how (peer-led programs, professional help, events, presentations/workshops, resources, support groups), what (self-care, counseling and education for one self, education for others, support for addressing sexuality/sexual health concerns, and concealing treatment-related changes), and who (team approach or delivered by women, health professionals, make-up artists). Conclusion: This study provides useful data on what women believe are the attributes of the ideal body image program, which can contribute to efforts aimed at developing and delivering body image programs for women diagnosed with breast cancer that prioritize their needs and preferences.

Effective behavior change techniques to promote physical activity in adults with overweight or obesity: A systematic review and meta-analysis

Multicomponent behavior change interventions are typically used in weight management, but results are largely heterogeneous and modest. Determining which techniques (behavior change technique [BCTs]) are more effective in changing behavior is thus required. This study aimed to identify the most effective BCTs for increasing physical activity (PA) in digital and face-to-face behavior change interventions in adults with overweight/obesity. Four databases were searched for eligible studies until October 2019. BCTs were coded using BCTTv1 and MBCT taxonomies. Sixty-two RCTs were included. Meta-regressions were performed to explore BCTs' moderating role. Five BCTs showed significant moderator effects on PA in digital interventions: goal setting behavior, goal setting outcome, graded tasks, social incentive, and self-monitoring of behavior (adjusted R² 's = 0.15-0.51). One BCT showed significant moderator effects on PA in face-to-face interventions, behavioral practice and rehearsal (adjusted R²  = 0.22). Multivariate and sensitivity analysis generally led to similar findings. Effective BCTs for increasing PA in adults with overweight/obesity in digital and face-to-face interventions seem to differ. Evidence suggests that using goal setting, social incentive, and graded tasks might help improve PA in digital interventions while avoiding inconsistent self-monitoring of behavior. In face-to-face interventions, prompting behavioral practice and rehearsal might lead to better PA outcomes. Still, further studies are needed. Implications of the current findings are discussed.

Predicting psychological factors affecting regular physical activity in hypertensive patients: Application of health action process approach model

Aim

The aim of this study was to determine the factors affecting the behaviour of regular physical activity in patients with hypertension using the health action process approach (HAPA) model.

Design

This cross-sectional study was conducted on 176 hypertension patients, in Astaneh-e-Ashrafiyeh, Guilan, Iran, 2018-2019.

Methods

Data collection tools included demographic characteristics, medical history, the short form of International Physical Activity Questionnaire (IPAQ) and scales related to the HAPA model. The data were analysed using chi-square, independent t test, one-way ANOVA, Pearson's correlation coefficient and path analysis on AMOS, version 23.0.

Results

Action self-efficacy (β = 0.59), outcome expectancy (β = 0.20) and risk perception (β = 0.18) had a statistically significant effect on intention. Moreover, the path coefficient between intention (β = 0.35) and coping self-efficacy (β = 0.29) with physical activity was statistically significant. The results revealed that HAPA constructs were able to describe 45% of the variance in intention and 31% of the variance in physical activity behaviour.

Conclusion

The HAPA model is a useful framework for describing the factors affecting physical activity in hypertension patients.

Theory in practice: identifying theory-based techniques in health coaches' tailored feedback during a weight loss intervention

Objective: A taxonomy of ninety-three functionally different behaviour change techniques (BCTs) has been identified. However, it is not fully clear how these and other theory-based techniques are applied in the day-to-day practice of people delivering health behaviour change interventions. This study examines feedback provided by expert health coaches in a behavioural weight-loss intervention, to describe; a) what theory-based techniques are used in sessions, b) which techniques are used most frequently, c) what occurs in sessions, beyond existing theory-based techniques. Main Outcome Measures: Theory-based techniques (BCTs/tailoring strategies); relational/content-based techniques. Design: 10 tailored feedback videos from two health coaches were coded using a hybrid thematic analysis approach. Theory-based techniques were coded deductively; content not matching definitions of theory-based techniques but that addressed a determinant of behaviour change were coded inductively and relational codes were connected into themes. Results: Seventeen BCTs were coded M = 20.88 times (range:1-109). Eight tailoring techniques were coded M = 25.25 times (range:1-91). Relational themes included; 'Autonomous interpersonal coaching style,' 'Supportive accountability,' and 'Coach as expert'. Additional behavioural techniques were also identified. Conclusion: This work highlights what and how theory-based techniques are implemented in a weight-loss intervention, drawing attention to the role of tailoring techniques and health coaches in supporting behaviour change.

Measuring fidelity to behavioural support delivery for smoking cessation and its association with outcomes

BACKGROUND AND AIMS

Behavioural support increases smoking cessation in clinical settings, but effect sizes differ among providers, due possibly to variations in delivery. This study evaluates a measure ('fidelity index') intended to capture fidelity to delivery of content- and interaction-based items of a behavioural support (BS) for smoking cessation and the association of fidelity with quit rates.

METHODS

A fidelity index for scoring the adherence and quality domains of a specific BS intervention, '5As for quit', was developed by classifying the intervention components using the taxonomy of behaviour change techniques. The index was applied to code 154 BS sessions audiotaped among 18 chest clinics in Pakistan to assess their fidelity and explore reliability of coding. The association between intervention fidelity and successful quit achieved by the same providers in a previous study was explored using regression analysis.

RESULTS

The index represented two domains: adherence to delivery of content-based activities of 5As (37 items) and quality of interaction-based activities (eight items). The intercoder reliability was good for content-based (average Krippendorff's α = 0.80) and moderate for interaction-based (average Krippendorff's α = 0.66) items. Approximately 70% (intraclass correlation coefficient: adherence scores = 0.72, quality scores = 0.71) of variation in BS delivery was contributed by providers, which increased to 97% (g-coefficient: adherence scores = 0.973, quality scores = 0.974) after accounting for other sources of variation. Higher quit rates were positively associated with average quality scores [risk ratio = 2.15; 95% confidence interval (CI) = 1.43-3.24], but negatively associated with average adherence scores (risk ratio = 0.55; 95% CI = 0.40-0.77) within services.

CONCLUSIONS

The fidelity index is a reliable measure for quantifying intervention fidelity of delivering smoking cessation behavioural support. Recommended revisions of the fidelity index include incorporation of additional interaction-based items, such as the relational techniques used in motivational interviewing.

A school-based intervention based on self-determination theory to promote girls' physical activity: study protocol of the CReActivity cluster randomised controlled trial

BACKGROUND

Physical inactivity is deemed to be the fourth leading cause for premature death. Nevertheless, only a minority of children and adolescents in Germany fulfil the guideline of the World Health Organization of at least 60 min of moderate-to-vigorous physical activity per day. Children and adolescents with a lower socioeconomic background and especially girls are regarded as a high-risk group in terms of physical inactivity. Aim of this study is to examine how a theory-based physical education intervention programme supporting students' autonomy, competence and relatedness affects physical activity both during these lessons and in leisure time. Based on the self-determination theory and the social cognitive theory, the extent to which autonomy, competence, relatedness, social support and self-efficacy in girls mediate the effect of the intervention programme on their physical activity will be examined. Moreover, the potential moderating role of socioeconomic status, environmental factors, teacher characteristics and BMI will be tested.

METHODS

CReActivity is a two-arm cluster randomised controlled trial with a follow-up period of three months after the end of the intervention programme. A total of 600 sixth grade girls in lower secondary schools in Bavaria, Germany will be proactively recruited. The intervention is carried out by the physical education teachers of the participating classes for five months. Primary outcome is the girls' physical activity measured by accelerometers and systematic observations.

DISCUSSION

We expect to provide an intervention programme that can contribute to the increase of physical activity levels in girls and offer insights into the mechanisms of physical activity behaviour change.

Adherence to medication in adults with Cystic Fibrosis: An investigation using objective adherence data and the Theoretical Domains Framework

OBJECTIVES

Adherence to nebulizer treatment in adults with Cystic Fibrosis (CF) is poor, and interventions are needed. This research aimed to identify the factors affecting nebulizer adherence using the Theoretical Domains Framework (TDF) and to compare these for participants with different levels of adherence.

DESIGN

Data-prompted interviews using the TDF.

METHODS

Eighteen semi-structured interviews were conducted with adults with CF during which objectively measured adherence data were discussed. Framework analysis was used to code the data into TDF domains, and inductive qualitative content analysis was used to code different beliefs and experiences. Aspects of the TDF that differed between participants with different adherence levels were explored.

RESULTS

Factors influencing adherence to treatment included all 14 domains of the TDF, 10 of which appeared to vary by adherence level: Skills; Memory and decision-making; and Behavioural regulation; Environmental context and resources; Social influences; Beliefs about consequences; Beliefs about capability; Reinforcement; Social role and identify; Intentions; Optimism; and Emotions.

CONCLUSIONS

This study is the first to use objectively measured adherence data in a data-prompted interview using the TDF framework to systematically assess the full range of factors potentially influencing adherence. The results highlighted that interventions need to consider issues of capability, opportunity, and motivation. Interventions that challenge dysfunctional beliefs about adherence and which support the development of routines or habits and problem-solving may be particularly useful for adults with CF. Statement of contribution What is already known? Adherence to medication in adults with cystic fibrosis is poor. Previous research has identified a range of contributing factors in relation to subjective reports of adherence. There is a wide discrepancy between self-reported adherence and objectively measured adherence. What this study adds A data-prompted interview using objectively measured adherence data enabled the systematic assessment of potential factors that could be targeted in an intervention to increase adherence. There were some differences in the factors that were identified by high and low adherers. There is not one-size fits all intervention for adherence to medication in cystic fibrosis.

Use of dynamic systems methods to characterize dyadic interactions in smoking cessation behavioural support sessions: A feasibility study

BACKGROUND

Understanding how behaviour change techniques (BCTs) operate in practice requires a method for characterizing the reciprocal, dynamic, and real-time nature of behavioural support interactions between practitioners and clients. State space grids (SSGs) are an observational, dynamic systems methodology used to map the trajectory of dyadic interactions in real time. By mapping the flow of events in terms of practitioner and client actions, SSGs are potentially well suited to characterize behavioural support sessions.

PURPOSE

To develop reliable methods and examine the feasibility of using the SSG methodology for characterizing practitioners' delivery of and clients' response to BCTs in smoking cessation behavioural support sessions.

METHODS

Smoking cessation behavioural support sessions were video-recorded and transcribed verbatim (n = 6 recordings; 2,916 statements). All speech was coded independently by two researchers for content and duration using published frameworks for specifying practitioner-delivered and client-received BCTs in smoking cessation interactions. Inter-rater reliability was assessed. Indices of practitioner-client interaction dynamics were derived: (1) reciprocity (i.e., attractor states, content congruence, conditional pairing) and (2) temporal patterning (i.e., variability, inter-grid distance, combinatory micro-patterning, sessional macropatterning). The extent to which indices can describe differences between sessions involving different practitioners and clients was examined.

RESULTS

Inter-rater reliability was moderate at 72% agreement. Indices of reciprocity and temporal patterning characterized differences between sessions involving different practitioners and clients.

CONCLUSIONS

State space grids provide a method for characterizing the complexity and variability of practitioner-delivered and client-received BCTs in behavioural support sessions. This method has potential to add explanatory value to smoking cessation intervention outcomes. Statement of Contribution What is already known on this subject? Frameworks exist for characterizing practitioner-delivered and client-received behaviour change techniques (BCTs). Methods are still needed to investigate which BCTs are effective under what conditions. State space grids (SSGs) are a dynamic systems method that may better characterize behavioural support interactions. What does this study add? First reliable, dynamic systems, SSG coding procedures, methods, and measures to characterize behavioural support. A method for examining reciprocality and temporal patterning of BCT delivery and receipt. Establishes a dynamic systems method that adds explanatory value to the outcomes of interventions.

Understanding Outcomes in Behavior Change Interventions to Prevent Pediatric Obesity: The Role of Dose and Behavior Change Techniques

BACKGROUND

Behavioral interventions to prevent pediatric obesity have shown inconsistent results across the field. Studying what happens within the "black box" of these interventions and how differences in implementation lead to different outcomes will help researchers develop more effective interventions.

AIM

To compare the implementation of three features of a phone-based intervention for parents (time spent discussing weight-related behaviors, behavior change techniques used in sessions, and intervention activities implemented by parents between sessions) with study outcomes.

METHODS

A random selection of 100 parent-child dyads in the intervention arm of a phone-based obesity prevention trial was included in this analysis. Sessions were coded for overall session length, length of time spent discussing specific weight-related behaviors, number of behavior change techniques used during the sessions, and number of intervention-recommended activities implemented by the parents between sessions (e.g., parent-reported implementation of behavioral practice/rehearsal between sessions). The primary study outcome, prevention of unhealthy increase in child body mass index (BMI) percentile, was measured at baseline and 12 months.

RESULTS

Overall session length was associated with decreases in child BMI percentile ( b = -0.02, p = .01). There was no association between the number of behavior change techniques used in the sessions and decreases in child BMI percentile ( b = -0.29, p = .27). The number of activities the parents reported implementing between sessions was associated with decreases in child BMI percentile ( b = -1.25, p = .02).

DISCUSSION

To improve future interventions, greater attention should be paid to the intended and delivered session length, and efforts should be made to facilitate parents' implementation of intervention-recommended activities between sessions (ClinicalTrials.gov, No. NCT01084590).

Developing Behavior Change Interventions for Self-Management in Chronic Illness: An Integrative Overview

More people than ever are living longer with chronic conditions such as obesity, type 2 diabetes, and heart disease. Behavior change for effective self-management can improve health outcomes and quality of life in people living with such chronic illnesses. The science of developing behavior change interventions with impact for patients aims to optimize the reach, effectiveness, adoption, implementation, and maintenance of interventions and rigorous evaluation of outcomes and processes of behavior change. The development of new services and technologies offers opportunities to enhance the scope of delivery of interventions to support behavior change and self-management at scale. Herein, we review key contemporary approaches to intervention development, provide a critical overview, and integrate these approaches into a pragmatic, user-friendly framework to rigorously guide decision-making in behavior change intervention development. Moreover, we highlight novel emerging methods for rapid and agile intervention development. On-going progress in the science of intervention development is needed to remain in step with such new developments and to continue to leverage behavioral science's capacity to contribute to optimizing interventions, modify behavior, and facilitate self-management in individuals living with chronic illness.

An assessment of physiotherapist's delivery of behaviour change techniques within the SOLAS feasibility trial

OBJECTIVES

To investigate physiotherapist's (PTs) fidelity to 31 protocol-listed behaviour change techniques (BCTs) during a group-based self-management intervention. This study also explored the PTs delivery of these BCTs beyond the present or absent dichotomy, using a third variable, partial delivery (i.e., attempted).

DESIGN

Assessment of the intervention arm of the Self-management of Osteoarthritis and Low back pain through Activity and Skills (SOLAS) cluster, randomized controlled feasibility trial, using quantitative methods.

METHODS

Eight PTs delivered six SOLAS classes each, of which 50% were audio-recorded and transcribed. Transcripts were coded by two raters using the Behaviour Change Technique Taxonomy v1 and an intervention-specific manual and assessed for the delivery (i.e., full, partial, or absent) of the 31 BCTs and their target behaviours. Fidelity was calculated as fully delivered BCTs listed as a percentage of those due to take place within each class.

RESULTS

Physiotherapists delivered a mean 20.5 BCTs per class (68.3%; range = 64.9-72.4%). Of these, 17 BCTs were fully delivered in each class representing moderate fidelity to the protocol (56.8%; range = 53.5-59.3%). A further 3.5 BCTs per class (11.5%; range = 8.7-14.8%) were partially delivered. BCTs associated with 'goals and planning' were often poorly delivered.

CONCLUSIONS

Delivering the SOLAS intervention BCTs with high fidelity was not feasible. The assessment of partial delivery of BCTs provided greater insight into the techniques that should be removed from the protocol or that may require further training. Complex interventions should consider a list of 'core' or mandatory BCTs alongside 'optional' BCTs, depending on the target behaviour, and the needs of individual participants. Statement of contribution What is already known on this subject? BCTs are the smallest active components of behavioural interventions, yet typically their effectiveness is determined through meta-analyses. Attempted delivery of BCTs is often unaccounted for yet may provide valuable insight into difficulty with delivery. There is a need to investigate BCT implementation beyond simple presence/absence to identify protocol refinements or required BCT training. What does this study add? BCT delivery was assessed in greater depth than previous research, including partial delivery. Highlights the need for appropriate training in BCTs that are difficult to deliver, particularly those associated with 'goals and planning' Highlights the need for intervention-specific criteria as to what constitutes 'high', 'moderate', and 'low' fidelity.

Teaching Quality in Math Class: The Development of a Scale and the Analysis of Its Relationship with Engagement and Achievement

Math achievement and engagement declines in secondary education; therefore, educators are faced with the challenge of engaging students to avoid school failure. Within self-determination theory, we address the need to assess comprehensively student perceptions of teaching quality that predict engagement and achievement. In study one we tested, in a sample of 548 high school students, a preliminary version of a scale to assess nine factors: teaching for relevance, acknowledge negative feelings, participation encouragement, controlling language, optimal challenge, focus on the process, class structure, positive feedback, and caring. In the second study, we analyzed the scale's reliability and validity in a sample of 1555 high school students. The scale showed evidence of reliability, and with regard to criterion validity, at the classroom level, teaching quality was a predictor of behavioral engagement, and higher grades were observed in classes where students, as a whole, displayed more behavioral engagement. At the within level, behavioral engagement was associated with achievement. We not only provide a reliable and valid method to assess teaching quality, but also a method to design interventions, these could be designed based on the scale items to encourage students to persist and display more engagement on school duties, which in turn bolsters student achievement.

Effective behaviour change techniques for physical activity and healthy eating in overweight and obese adults; systematic review and meta-regression analyses

PURPOSE

This systematic review aims to explain the heterogeneity in results of interventions to promote physical activity and healthy eating for overweight and obese adults, by exploring the differential effects of behaviour change techniques (BCTs) and other intervention characteristics.

METHODS

The inclusion criteria specified RCTs with ≥ 12 weeks' duration, from January 2007 to October 2014, for adults (mean age ≥ 40 years, mean BMI ≥ 30). Primary outcomes were measures of healthy diet or physical activity. Two reviewers rated study quality, coded the BCTs, and collected outcome results at short (≤6 months) and long term (≥12 months). Meta-analyses and meta-regressions were used to estimate effect sizes (ES), heterogeneity indices (I²) and regression coefficients.

RESULTS

We included 48 studies containing a total of 82 outcome reports. The 32 long term reports had an overall ES = 0.24 with 95% confidence interval (CI): 0.15 to 0.33 and I² = 59.4%. The 50 short term reports had an ES = 0.37 with 95% CI: 0.26 to 0.48, and I² = 71.3%. The number of BCTs unique to the intervention group, and the BCTs goal setting and self-monitoring of behaviour predicted the effect at short and long term. The total number of BCTs in both intervention arms and using the BCTs goal setting of outcome, feedback on outcome of behaviour, implementing graded tasks, and adding objects to the environment, e.g. using a step counter, significantly predicted the effect at long term. Setting a goal for change; and the presence of reporting bias independently explained 58.8% of inter-study variation at short term. Autonomy supportive and person-centred methods as in Motivational Interviewing, the BCTs goal setting of behaviour, and receiving feedback on the outcome of behaviour, explained all of the between study variations in effects at long term.

CONCLUSION

There are similarities, but also differences in effective BCTs promoting change in healthy eating and physical activity and BCTs supporting maintenance of change. The results support the use of goal setting and self-monitoring of behaviour when counselling overweight and obese adults. Several other BCTs as well as the use of a person-centred and autonomy supportive counselling approach seem important in order to maintain behaviour over time.

Effective behaviour change techniques for physical activity and healthy eating in overweight and obese adults; systematic review and meta-regression analyses

Purpose

This systematic review aims to explain the heterogeneity in results of interventions to promote physical activity and healthy eating for overweight and obese adults, by exploring the differential effects of behaviour change techniques (BCTs) and other intervention characteristics.

Methods

The inclusion criteria specified RCTs with ≥ 12 weeks’ duration, from January 2007 to October 2014, for adults (mean age ≥ 40 years, mean BMI ≥ 30). Primary outcomes were measures of healthy diet or physical activity. Two reviewers rated study quality, coded the BCTs, and collected outcome results at short (≤6 months) and long term (≥12 months). Meta-analyses and meta-regressions were used to estimate effect sizes (ES), heterogeneity indices (I²) and regression coefficients.

Results

We included 48 studies containing a total of 82 outcome reports. The 32 long term reports had an overall ES = 0.24 with 95% confidence interval (CI): 0.15 to 0.33 and I² = 59.4%. The 50 short term reports had an ES = 0.37 with 95% CI: 0.26 to 0.48, and I² = 71.3%. The number of BCTs unique to the intervention group, and the BCTs goal setting and self-monitoring of behaviour predicted the effect at short and long term. The total number of BCTs in both intervention arms and using the BCTs goal setting of outcome, feedback on outcome of behaviour, implementing graded tasks, and adding objects to the environment, e.g. using a step counter, significantly predicted the effect at long term. Setting a goal for change; and the presence of reporting bias independently explained 58.8% of inter-study variation at short term. Autonomy supportive and person-centred methods as in Motivational Interviewing, the BCTs goal setting of behaviour, and receiving feedback on the outcome of behaviour, explained all of the between study variations in effects at long term.

Conclusion

There are similarities, but also differences in effective BCTs promoting change in healthy eating and physical activity and BCTs supporting maintenance of change. The results support the use of goal setting and self-monitoring of behaviour when counselling overweight and obese adults. Several other BCTs as well as the use of a person-centred and autonomy supportive counselling approach seem important in order to maintain behaviour over time.

Predicting Physical Activity-Related Outcomes in Overweight and Obese Adults: A Health Action Process Approach

BACKGROUND

We tested the adequacy of a model based on the Health Action Process Approach (HAPA) in predicting changes in psychological, body composition, and cardiovascular risk outcomes with respect to physical activity participation in overweight and obese adults.

METHODS

Measures of HAPA constructs (action and maintenance self-efficacy, outcome expectancies, action planning, risk perceptions, intentions, behaviour), psychological outcomes (quality of life, depression, anxiety, stress symptoms), body composition variables (body weight, body fat mass), cardiovascular risk measures (total cholesterol, low density lipoprotein), and self-reported physical activity behaviour were administered to participants (N = 74) at baseline, and 6 and 12 weeks later.

RESULTS

Data were analysed using variance-based structural equation modelling with residualised change scores for HAPA variables. The model revealed effects of action self-efficacy and outcome expectancies on physical activity intentions, action self-efficacy on maintenance self-efficacy, and maintenance self-efficacy and intentions on action planning. Intention predicted psychological and body composition outcomes indirectly through physical activity behaviour. Action planning was a direct predictor of psychological, cardiovascular, and body composition outcomes.

CONCLUSIONS

Data supported HAPA hypotheses in relation to intentions and behaviour, but not the role of action planning as a mediator of the intention-behaviour relationship. Action planning predicted outcomes independent of intentions and behaviour.

The Trans-Contextual Model of Autonomous Motivation in Education: Conceptual and Empirical Issues and Meta-Analysis

The trans-contextual model outlines the processes by which autonomous motivation toward activities in a physical education context predicts autonomous motivation toward physical activity outside of school, and beliefs about, intentions toward, and actual engagement in, out-of-school physical activity. In the present article, we clarify the fundamental propositions of the model and resolve some outstanding conceptual issues, including its generalizability across multiple educational domains, criteria for its rejection or failed replication, the role of belief-based antecedents of intentions, and the causal ordering of its constructs. We also evaluate the consistency of model relationships in previous tests of the model using path-analytic meta-analysis. The analysis supported model hypotheses but identified substantial heterogeneity in the hypothesized relationships across studies unattributed to sampling and measurement error. Based on our meta-analysis, future research needs to provide further replications of the model in diverse educational settings beyond physical education and test model hypotheses using experimental methods.

Implementation intention and planning interventions in Health Psychology: Recommendations from the Synergy Expert Group for research and practice

The current article details a position statement and recommendations for future research and practice on planning and implementation intentions in health contexts endorsed by the Synergy Expert Group. The group comprised world-leading researchers in health and social psychology and behavioural medicine who convened to discuss priority issues in planning interventions in health contexts and develop a set of recommendations for future research and practice. The expert group adopted a nominal groups approach and voting system to elicit and structure priority issues in planning interventions and implementation intentions research. Forty-two priority issues identified in initial discussions were further condensed to 18 key issues, including definitions of planning and implementation intentions and 17 priority research areas. Each issue was subjected to voting for consensus among group members and formed the basis of the position statement and recommendations. Specifically, the expert group endorsed statements and recommendations in the following areas: generic definition of planning and specific definition of implementation intentions, recommendations for better testing of mechanisms, guidance on testing the effects of moderators of planning interventions, recommendations on the social aspects of planning interventions, identification of the preconditions that moderate effectiveness of planning interventions and recommendations for research on how people use plans.

Using Visual Methods to Understand Physical Activity Maintenance following Cardiac Rehabilitation

Few studies have explored the factors associated with long-term maintenance of exercise following cardiac rehabilitation. The present study used auto-photography and interviews to explore the factors that influence motivation and continued participation in physical activity among post cardiac rehabilitation patients. Twenty-three semi-structured interviews were conducted alongside participant-selected photographs or drawings with participants that had continued participation in physical activity for at least two years following the cardiac rehabilitation programme. Participants were recruited from circuit training classes in East Sussex in the UK. Thematic content analysis revealed seven main themes: fear of death and ill health avoidance, critical incidents, overcoming aging, social influences, being able to enjoy life, provision of routine and structure, enjoyment and psychological well-being. Fear of death, illness avoidance, overcoming aging, and being able to enjoy life were powerful motives for continued participation in exercise. The social nature of the exercise class was also identified as a key facilitator of continued participation. Group-based exercise suited those that continued exercise participation post cardiac rehabilitation and fostered adherence.

Weight-loss intervention using implementation intentions and mental imagery: a randomised control trial study protocol

BACKGROUND

Overweight and obesity are major health problems worldwide. This protocol describes the HEALTHI (Healthy Eating and Active LifesTyle Health Intervention) Program, a 12-week randomised-controlled weight-loss intervention that adopts two theory-based intervention techniques, mental imagery and implementation intentions, a behaviour-change technique based on planning that have been shown to be effective in promoting health-behaviour change in previous research. The effectiveness of goal-reminder text messages to augment intervention effects will also be tested. The trial will determine the effects of a brief, low cost, theory-based weight-loss intervention to improve dietary intake and physical activity behaviour and facilitate weight-loss in overweight and obese individuals.

METHODS/DESIGN

Overweight or obese participants will be randomly allocated to one of three conditions: (1) a psycho-education plus an implementation intentions and mental imagery condition; (2) a psycho-education plus an implementation intentions and mental imagery condition with text messages; or (3) a psycho-education control condition. The intervention will be delivered via video presentation to increase the intervention's applicability in multiple contexts and keep costs low. We hypothesise that the intervention conditions will lead to statistically-significant changes in the primary and secondary outcome variables measured at 6 and 12 weeks post-intervention relative to the psycho-education control condition after controlling for baseline values. The primary outcome variable will be body weight and secondary outcome variables will be biomedical (body mass, body fat percentage, muscle mass, waist-hip circumference ratio, systolic and diastolic blood pressure, low-density lipoprotein, high-density lipoprotein, total cholesterol, triglycerides, blood glucose and insulin levels), psychological (quality of life, motivation, risk perception, outcome expectancy, intention, action self-efficacy, maintenance self-efficacy, goal setting and planning), and behavioural (self-reported diet intake, and physical activity involvement) measures. We also expect the intervention condition augmented with text messages to lead to statistically significant differences in the primary and secondary outcome variables at the follow up periods after controlling for baseline values.

DISCUSSION

The planned trial will test the effectiveness of the theory-based HEALTHI program intervention to reduce weight and salient psychological, biomedical, and behavioural outcomes in overweight and obese adults. The study has been designed to maximise applicability to real world settings and could be integrated into existing weight management practices.

Autonomous and controlled motivational regulations for multiple health-related behaviors: between- and within-participants analyses

Self-determination theory has been applied to the prediction of a number of health-related behaviors with self-determined or autonomous forms of motivation generally more effective in predicting health behavior than non-self-determined or controlled forms. Research has been confined to examining the motivational predictors in single health behaviors rather than comparing effects across multiple behaviors. The present study addressed this gap in the literature by testing the relative contribution of autonomous and controlling motivation to the prediction of a large number of health-related behaviors, and examining individual differences in self-determined motivation as a moderator of the effects of autonomous and controlling motivation on health behavior. Participants were undergraduate students (N = 140) who completed measures of autonomous and controlled motivational regulations and behavioral intention for 20 health-related behaviors at an initial occasion with follow-up behavioral measures taken four weeks later. Path analysis was used to test a process model for each behavior in which motivational regulations predicted behavior mediated by intentions. Some minor idiosyncratic findings aside, between-participants analyses revealed significant effects for autonomous motivational regulations on intentions and behavior across the 20 behaviors. Effects for controlled motivation on intentions and behavior were relatively modest by comparison. Intentions mediated the effect of autonomous motivation on behavior. Within-participants analyses were used to segregate the sample into individuals who based their intentions on autonomous motivation (autonomy-oriented) and controlled motivation (control-oriented). Replicating the between-participants path analyses for the process model in the autonomy- and control-oriented samples did not alter the relative effects of the motivational orientations on intention and behavior. Results provide evidence for consistent effects of autonomous motivation on intentions and behavior across multiple health-related behaviors with little evidence of moderation by individual differences. Findings have implications for the generalizability of proposed effects in self-determination theory and intentions as a mediator of distal motivational factors on health-related behavior.
