Evaluating the feasibility and utility of telephonic motivational interviewing in older adults

Older adults face unique barriers and challenges related to physical activity (PA) participation. Motivational interviewing (MI) is a commonly used health coaching strategy to support behavior change that holds potential for older adults. Previous research on MI strategies has focused primarily on face-to-face delivery, limiting insights regarding virtual programs.

Objectives

The purpose of this study was to determine if MI could be delivered telephonically with high fidelity and high acceptability in older adult participants. The study is designed to inform future trials evaluating its effectiveness in supporting virtual PA programs.

Methods

This study evaluated the feasibility and acceptability of telephonic MI among older adults that enrolled in an online version of the Walk with Ease program.

Results

Of 39 participants referred, 29 enrolled and 27 provided feedback. Participants were highly accepting and adherent, with 74 % of patients attending at least five of six sessions, and 96 % of participants indicating satisfaction with the MI provided. Coaches improved program enjoyment by helping set effective goals and providing ongoing accountability.

Conclusions

Evaluations documented adequate fidelity and high acceptability of telephonic delivery, and motivation results revealed large, significant increases in autonomous regulation (quality of motivation).

Innovation

Telephonic MI using non-healthcare professional coaches is feasibly delivered with high fidelity, and is acceptable to older adult participants. The innovative delivery format offers novel opportunities supporting virtual and telehealth interventions to reduce chronic disease risk among older adults.

A full-factorial test of motivational and volitional intervention strategies for promoting exercise habit formation and exercise maintenance among new users of an online exercise class platform

Interventions often fail to achieve long-term behavioral maintenance. Utilizing motivational and volitional strategies to promote behavioral maintenance factors may improve this. Using a full-factorial experiment, we tested the effects of three intervention components (focused on intrinsic motivation and identity, exercise preparation habit, and exercise instigation habit) on exercise participation over a year, among new users (N = 751; 91% identifying as female, 54% identifying as White race) of a global, online exercise class platform, run by Les Mills International Ltd, called LM+. We also tested the intervention components' theoretical mechanisms of action-habit formation, intrinsic motivation, identity, and self-efficacy. Multi-level models found some support for a main effect of the exercise preparation habit intervention component in promoting self-reported and objective exercise participation (behavioral outcomes measured via monthly surveys and the LM+ platform; mechanisms measured via monthly surveys)-in particular online exercise class frequency (fixed effect estimate = 0.84, p < 0.05, and = 0.12, p < 0.05, respectively). The preparation habit component also significantly increased preparation habit strength (0.30, p < 0.05) and instigation habit strength (0.33, p < 0.05). Other expected effects were nonsignificant. Helping individuals form an exercise preparation habit may facilitate initiating and maintaining exercise over time, in particular for attending online exercise classes, potentially through promoting greater preparation and exercise instigation habit strength.

Confirming the Causal Role of Consistent Contexts in Developing a Walking Habit: A Randomized Comparison With Varied Contexts

BACKGROUND

Physical activity interventions using habit development may help people increase and then maintain physical activity increases over time. Enacting behavior in consistent contexts is a central component of habit development, yet its causal role in habit development in health behaviors has not been confirmed.

PURPOSE

This study tests the causal role of consistent context in habit development in health behavior, using a randomized control trial of a planning intervention to develop a walking habit in 127 insufficiently active, working, midlife adults in a real-world setting.

METHODS

We compare participants who plan walking in consistent contexts with controls who plan walking in varied contexts and with controls not required to plan on a change in average daily steps (measured using an accelerometer) and inhabit automaticity during a 4-week intervention and at a 4-week follow-up.

RESULTS

As expected, consistent and varied context planners increased walking during the intervention, but only consistent context planners developed (and maintained) habit automaticity. Counter to expectations, consistent context planners did not show walking maintenance. However, across conditions, participants who developed more habit automaticity during the intervention also maintained walking more (decreased less). Having a routine daily schedule moderated some effects. Notably, no-plan controls with greater routine developed more habit automaticity, mediated by walking in more consistent contexts.

CONCLUSIONS

This study confirms the causal role of consistent contexts in developing a walking habit, in a real-world setting, with an important but challenging population for physical activity interventions and identifies a facilitating condition common for many: a routine schedule.

Understanding aberrant driving intentions based on the Theory of Planned Behavior: Literature review and Meta-Analysis

INTRODUCTION

Despite deployed efforts to establish strict road safety standards, human factors is still the leading cause of road crashes. To identify determinants of driver's behavior, TPB (Theory of Planned Behavior) is widely used as a prominent theory of behavior change. However, the existence of different aberrant driving behaviors (decision errors, recognition errors, violations, and physical condition related errors) and several studies using TPB to understand driving behavior, makes it important to conduct a literature review and a meta-analysis of existing studies to use their results in effective driving behavior change interventions.

METHOD

The selection process provided 125 relevant studies that were published between 1991 and 2022, and that used TPB for the understanding of aberrant driving behavior. Five fundamental research questions were defined to identify information to be discovered from the literature review and from the meta-analysis.

RESULTS

In addition to the standard TPB constructs (attitudes, subjective norms, and perceived behavioral control), past behavior, moral norms, and descriptive norms were used in studies for a more comprehensive understanding of aberrant driving intention. This analysis demonstrated a significant correlation between aberrant driving intentions and past behavior. Also, moral norms construct was correlated with violations and recognition errors, whereas descriptive norms construct was correlated just with recognition errors.

CONCLUSIONS

The results of this study highlight the strength of TPB in the prediction of aberrant driving intention and its potential effectiveness to guide interventions aimed at changing aberrant driving behaviors. The study contributes to the comprehension of the relevant psychological factors influencing the engagement of drivers in each category of aberrant driving behaviors.

PRACTICAL APPLICATIONS

Researchers can use the results of this study to select the relevant psychological factors adapted to their interventions of driving behavior change. The results of the meta-analysis can also be used in the prediction of driver's intentions.

Gender differences in sleep behaviors under China's universal two-child policy

Since 2016, China has progressively relaxed family planning policies to stimulate birth rates. This paper examines the behavioral health repercussions of China's 2016 universal two-child policy (UTCP) by analyzing sleep pattern data from China Family Panel Studies. Napping is a composite indicator that denotes health outcomes, job quality, and personal well-being. It reveals work conditions and environments to some extent. UTCP may lead to heightened social expectations regarding pregnancy likelihood, and changes in social expectations within the workplace may make work environments less equitable and more stressful for females. Leveraging a difference-in-difference model, this paper explores how napping behaviors among the working-age cohort have responded to the policy shifts. Our analysis reveals a gender discrepancy in response to the policy, specifically, females exhibit a discernible reduction in the likelihood of napping, as well as in the duration of both daytime naps and daily sleep. Conversely, such effects are not significant among males. These results suggest policy consequences extend beyond individuals directly impacted by childbirth or contemplating parenthood. Hence, while promoting fertility is still the government's goal, policymakers are encouraged to consider the broader challenges the female population faces from social and workplace environment factors.

Motivation toward physical activity in patients with chronic musculoskeletal disorders: a meta-analysis of the efficacy of behavioural interventions

Musculoskeletal disorders (MDs) represent a global health issue, which can lead to disability. Physical activity (PA) reduces pain and increases physical function among patients with MDs. To promote behavioural changes, it seems important to focus on modifiable factors, such as motivation. Thus, this review aims to assess effects of interventions targeting PA on motivation towards PA. Searches used terms referring to "physical activity", "motivation" and "chronic musculoskeletal disorders" on the databases PubMed, PsychINFO, MEDLINE, EMBASE, PEDro and Web of Science. All types of intervention-including but not limited to RCTs-were eligible for inclusion. Risk of bias was assessed with the Quality Assessment Tool for Studies with Diverse Designs (QATSDD). Among 6 489 abstracts identified, there were 387 eligible studies and 19 were included, reporting in total 34 effect sizes. The meta-analysis concerned 1 869 patients and indicated a small effect of interventions on change in motivation towards PA (d = 0.34; 95% CI [0.15; 0.54]; p < .01; k = 33). Behavioural interventions positively impact PA motivation in patients with MDs. In the literature, most studies focused on intervention's effect on fear of movement. Future research should assess other explicit motivational constructs, as well as implicit processes.

Towards implementation of cognitive bias modification in mental health care: State of the science, best practices, and ways forward

Cognitive bias modification (CBM) has evolved from an experimental method testing cognitive mechanisms of psychopathology to a promising tool for accessible digital mental health care. While we are still discovering the conditions under which clinically relevant effects occur, the dire need for accessible, effective, and low-cost mental health tools underscores the need for implementation where such tools are available. Providing our expert opinion as Association for Cognitive Bias Modification members, we first discuss the readiness of different CBM approaches for clinical implementation, then discuss key considerations with regard to implementation. Evidence is robust for approach bias modification as an adjunctive intervention for alcohol use disorders and interpretation bias modification as a stand-alone intervention for anxiety disorders. Theoretical predictions regarding the mechanisms by which bias and symptom change occur await further testing. We propose that CBM interventions with demonstrated efficacy should be provided to the targeted populations. To facilitate this, we set a research agenda based on implementation frameworks, which includes feasibility and acceptability testing, co-creation with end-users, and collaboration with industry partners.

Emotional Distress and Physical Activity Engagement in U.S. Veterans With Chronic Obstructive Pulmonary Disease: A Qualitative Study

BACKGROUND

Physical activity is recommended as part of guideline-based care for managing chronic obstructive pulmonary disease (COPD) at all stages of the disease. However, physical activity interventions are less effective in individuals with co-occurring emotional distress (i.e., depression and/or anxiety symptoms). Interventions that dually promote improved physical and mental health in COPD are needed. The first step for intervention development is understanding individuals' experience of these factors.

PURPOSE

To understand the experience of emotional distress in U.S. Veterans diagnosed with COPD and to explore how emotional distress impacts physical activity engagement.

METHODS

Structured interviews informed by the cognitive and behavioral models of psychopathology were conducted with 29 United States Veterans with COPD (89.66% male, age 67.72 ± 6.55 years, 93.10% White) at the VA Boston Healthcare System. Interviews were audio recorded, transcribed, and underwent thematic analysis.

RESULTS

Three major themes encapsulating 17 codes emerged through thematic analysis: (i) the experience of emotional distress in Veterans with COPD; (ii) the complex relationship between emotional distress, physical activity engagement, and COPD; (iii) contextual and personal factors.

CONCLUSIONS

Veterans' interpretation of their COPD symptoms as unpredictable and uncontrollable and COPD-related physical limitations influenced their experience of emotional distress, while the experience of emotional distress both promoted and deterred physical activity engagement. Veterans were motivated to engage in physical activity despite experiencing emotional distress when they faced a responsibility in daily life. They identified motivational strategies and self-regulation techniques to manage emotional distress and to foster physical activity.

Autonomy support in an exercise intervention with colorectal cancer patients during chemotherapy: a qualitative perspective

OBJECTIVE

Physical activity (PA) has emerged as an important element of supportive care for cancer patients, but few patients engage with exercise. Considering that autonomy support is associated with healthy lifestyles, it would be useful to know the specific autonomy-supportive techniques that can help to encourage PA in colorectal cancer (CRC) patients. This study aims to qualitatively explore autonomy support perceptions through a self-determination-theory-based exercise program (FIT-CANCER) with CRC patients during chemotherapy treatment.

METHODS AND MEASURES

A total of 27 participants were included, 16 CRC patients, six relatives, and five healthcare professionals. Qualitative data from semi-structured interviews and observational field notes were analyzed with thematic analysis.

RESULTS

Three main themes were identified: Healthcare professionals encouraging enrollment in the exercise program, Relatives supporting attendance to the exercise sessions, Exercise instructor favoring adherence to the exercise program. The different subthemes showed autonomy-supportive techniques from these social agents to promote CRC patients' participation in the exercise program.

CONCLUSION

The present research showed the importance of autonomy support from healthcare professionals, relatives and the exercise instructor to promote the initiation and maintenance of CRC patients' PA behavior and improve their quality of life, health and well-being.

Focusing on neural mechanisms of exercise training benefits in multiple sclerosis

Exercise training (ET) should be a mainstay of comprehensive care in multiple sclerosis (MS), yet there is reluctance regarding its implementation among healthcare providers. This reluctance has its roots in the lack of evidence from randomized controlled trials (RCTs) that provide a neurobiological mechanism for beneficial outcomes. We argue that ET training is efficacious for improving mobility and cognitive dysfunction as hallmark consequences of MS, and propose an experimental medicine framework for guiding research focusing on CNS mechanisms-of-action for ET benefits. The framework establishes three hierarchical pathways as preconditions for applying a mediation framework in a fourth pathway for fully testing mechanistic research questions using a RCT. This paper describes the conceptual basis of the pathways, and then reviews the existing evidence within the pathways of the framework for ET effects on the CNS, mobility, and cognition in MS. Lastly, this paper discusses future directions and challenges for testing the pathways of the framework for advancing the evidence regarding CNS mechanisms of ET benefits in this population. Our objective is guiding the field toward evidence that facilitates the prescription and promotion of ET as a neurorestorative approach within MS clinical practice.

An ontology of mechanisms of action in behaviour change interventions

Background

Behaviour change interventions influence behaviour through causal processes called "mechanisms of action" (MoAs). Reports of such interventions and their evaluations often use inconsistent or ambiguous terminology, creating problems for searching, evidence synthesis and theory development. This inconsistency includes the reporting of MoAs. An ontology can help address these challenges by serving as a classification system that labels and defines MoAs and their relationships. The aim of this study was to develop an ontology of MoAs of behaviour change interventions.

Methods

To develop the MoA Ontology, we (1) defined the ontology's scope; (2) identified, labelled and defined the ontology's entities; (3) refined the ontology by annotating (i.e., coding) MoAs in intervention reports; (4) refined the ontology via stakeholder review of the ontology's comprehensiveness and clarity; (5) tested whether researchers could reliably apply the ontology to annotate MoAs in intervention evaluation reports; (6) refined the relationships between entities; (7) reviewed the alignment of the MoA Ontology with other relevant ontologies, (8) reviewed the ontology's alignment with the Theories and Techniques Tool; and (9) published a machine-readable version of the ontology.

Results

An MoA was defined as "a process that is causally active in the relationship between a behaviour change intervention scenario and its outcome behaviour". We created an initial MoA Ontology with 261 entities through Steps 2-5. Inter-rater reliability for annotating study reports using these entities was α=0.68 ("acceptable") for researchers familiar with the ontology and α=0.47 for researchers unfamiliar with it. As a result of additional revisions (Steps 6-8), 23 further entities were added to the ontology resulting in 284 entities organised in seven hierarchical levels.

Conclusions

The MoA Ontology extensively captures MoAs of behaviour change interventions. The ontology can serve as a controlled vocabulary for MoAs to consistently describe and synthesise evidence about MoAs across diverse sources.

Who follows through? Different factors predict initial commitment vs. Following through in a national survey of organ donor registration

OBJECTIVE

Little research has investigated factors that determine whether people falter in the face of an obstacle or successfully follow through on an initial commitment to act. We integrated multiple theories (the Reasoned Action Approach [RAA], Prototype Willingness Model, and anticipated regret theory) to test which factors predict initial commitment to register as an organ donor and to discover whether different factors predict initial commitment vs. following through with registration.

METHODS

Participants from a nationally representative UK sample (N = 1,008) reported their beliefs about organ donation and indicated their decision to register. An obstacle that participants could not foresee was that they had to complete registration in a second survey 3 days after making their initial commitment.

RESULTS

Findings showed that 14.8% of participants followed through, 19.7% demonstrated initial commitment, and 65.5% declined to register. Linear discriminant function analysis derived two functions that distinguished these registration patterns. The first function discriminated participants who declined to register from the other groups. The declined group had lower scores on RAA variables compared to their counterparts. The second function distinguished participants who made an initial commitment to register from those who followed through. Follow-through was associated with less anticipated negative affect, more favorable descriptive norms, and stronger identification with organ donors.

CONCLUSIONS

The present findings indicate that even modest friction leads to a large reduction in follow-through. Moreover, different factors influence initial commitment vs. following through. Whereas RAA variables predicted initial commitment, following through was a function of anticipated negative affect and social processes.

Self-Determination Theory and Workplace Outcomes: A Conceptual Review and Future Research Directions

Adaptive workplace outcomes, such as employee work engagement, job performance, and satisfaction are positively associated with physical and psychological well-being, while maladaptive workplace outcomes, including work-related disengagement, dissatisfaction, stress, boredom, fatigue, and burnout, are negatively associated with well-being. Researchers have applied self-determination theory to identify key motivational correlates of these adaptive work-related determinants and outcomes. Research applying the theory has consistently indicated that autonomous forms of motivation and basic psychological need satisfaction are related to better employee performance, satisfaction, and engagement, while controlled forms of motivation and need frustration are associated with increased employee burnout and turnover. Forms of motivation have also been shown to mediate relations between need satisfaction and adaptive workplace outcomes. Despite support for these associations, a number of limitations in research in the field have been identified, which place limits on the inferences that can be drawn. Noted limitations encompass an over-reliance on single-occasion, correlational data; few fit-for-purpose tests of theory mechanisms; and a lack of consideration of key moderating variables. In the current conceptual review, we discuss these limitations in turn, with specific reference to examples from the extant research applying the theory in workplace contexts, and provide a series of recommendations we expect will set the agenda for future studies applying the theory in the workplace. Based on our review, we make three key recommendations: we stress the need for studies adopting experimental and longitudinal designs to permit better inferences (i.e., causal and directional), highlight the need for intervention research to explicitly test mediation effects to provide evidence for theory mechanisms, and outline some candidate moderators of theory effects, including workplace context, job type, pay structure, and causality orientations. We expect these recommendations to set an agenda for future research applying self-determination theory in workplace contexts with a view to filling the current evidence gaps and improving evidential quality.

Factors influencing civil servants' willingness to implement cardiopulmonary resuscitation in Chongqing, China: Based on the theory of planned behavior

Background

Timely bystander cardiopulmonary resuscitation is the key to improving the survival rate of out-of-hospital cardiac arrest. Civil servants are potential bystander CPR providers. This study aimed to explore civil servants' willingness to implement CPR in Chongqing, identify the influencing factors and mechanisms affecting civil servants' willingness to perform CPR, and then seek countermeasures to improve civil servants' willingness to implement CPR.

Methods

We introduced the theory of perceived risk into the theory of planned behavior, developed a 7-point Likert scale based on the extended theory of planned behavior, and conducted a questionnaire survey on civil servants in Chongqing, China. Descriptive statistical analysis and one-way ANOVA were employed to explore respondents' willingness and differences. Structural equation modeling was used to analyze the relationship between attitude, subjective norm, perceived behavioral control and perceived risk and respondents' willingness to implement CPR.

Results

A total of 1235 valid questionnaires were included for analysis. 50.1 % of respondents were willing to implement CPR. Male, over 40 years old, living with the elderly, having previous experience performing CPR on another person, and having higher CPR knowledge scores were associated with a more positive willingness to perform CPR. Attitude, subjective norm and perceived behavioral control had significant positive effects on willingness, and the standardized regression coefficients were 0.164, 0.326 and 0.313, respectively. The perceived risk has a significant negative effect on willingness, and the standardized regression coefficient was -0.109. The four latent variables accounted for 44.2 % of the variance in the willingness of civil servants to implement CPR.

Conclusions

The willingness of civil servants in Chongqing to implement CPR needs to be improved, and the countermeasures to enhance the subjective norm and perceived behavioral control of civil servants should be emphasized, such as developing a social support network for rescuing conduct, establishing regular training mechanisms and improving the practical applicability and popularization of the Chinese-style "Good Samaritan Law" etc., to improve the willingness of civil servants in Chongqing to implement CPR.

Understanding the intention and behavior of psychological help-seeking among Chinese college students using theory of planned behavior: a three-month follow-up study

Underutilization of mental health services is common and associated with substantial suffering, mental disorders and death. The present study aimed to explore factors significantly affecting the professional psychological help-seeking behavior based on the Theory of Planned Behavior (TPB). A sample of 597 Chinese college students recruited online completed the questionnaires, which measured four constructs of TPB including help-seeking intention, attitude, subjective norm and perceived behavioral control in December 2020. Help-seeking behaviors were evaluated three months later in March 2021. A two-step structural equation modeling procedure was used to test the TPB model. Findings show that partially consistent with TPB, more positive attitudes about seeking professional help (Β = .258, p = .001) and higher perceived behavioral control (Β = .504, p < .001) directly predicted higher intention to seek mental health services, and perceived behavioral control (Β = .230, p = .006) directly predicted help-seeking behavior. However, behavioral intention (Β = -.017, p = .830) did not statistically significantly predict help-seeking behavior, while subjective norm (Β = .047, p = .356) did not predict help-seeking intention as well. The model accounted for 49.9% of the variance modeling help-seeking intention and 12.4% of the variance modeling help-seeking behavior. The results revealed the importance of attitude and perceived behavioral control in predicting help-seeking intention and behavior among Chinese college students and indicated that there existed a gap between intention and actual help-seeking behavior.

Furthering Scientific Inquiry for Weight Loss Maintenance: Assessing the Psychological Processes Impacted by a Low intensity Technology-Assisted Intervention (NULevel Trial)

BACKGROUND

NULevel was a randomized control trial to evaluate a technology-assisted weight loss maintenance (WLM) program in the UK. The program included: (a) a face-to-face goal-setting session; (b) an internet platform, a pedometer, and wirelessly connected scales to monitor and report diet, physical activity, and weight, and; (c) regular automated feedback delivered by mobile phone, tailored to participants' progress. Components were designed to target psychological processes linked to weight-related behavior. Though intervention participants showed increased physical activity, there was no difference in WLM between the intervention and control groups after 12 months (Sniehotta FF, Evans EH, Sainsbury K, et al. Behavioural intervention for weight loss maintenance versus standard weight advice in adults with obesity: A randomized controlled trial in the UK (NULevel Trial). PLoS Med. 2019; 16(5):e1002793. doi:10.1371/journal.pmed.1002793). It is unclear whether the program failed to alter targeted psychological processes, or whether changes in these processes failed to influence WLM.

PURPOSE

We evaluate whether the program influenced 16 prespecified psychological processes (e.g., self-efficacy and automaticity toward diet and physical activity), and whether these processes (at 6 months) were associated with successful WLM (at 12 months).

METHODS

288 adults who had previously lost weight were randomized to the intervention or control groups. The control group received wireless scales and standard advice via newsletters. Assessments occurred in person at 0, 6, and 12 months.

RESULTS

The intervention significantly altered 10 of the 16 psychological processes, compared with the control group. However, few processes were associated with WLM, leading to no significant indirect effects of the intervention via the processes on WLM.

CONCLUSIONS

Changes in targeted processes were insufficient to support WLM. Future efforts may more closely examine the sequence of effects between processes, behavior, and WLM.

Using the pet health information behaviour intervention model should make information prescriptions for pet guardians more effective

BACKGROUND

Studies on information behaviour related to companion animal's (pet) health have been carried out in different contexts and there have been attempts to modify and idealize these information behaviours.

OBJECTIVE

The purpose of this study is to apply the Pet Health Information Behaviour Intervention model in an empirical context and elaborate the theoretical contribution of the model to information behaviour research in the context of pet care and management.

METHODS

All the variables of the proposed model were quantified and tested through case study research involving 20 participants. Each case consisted of a guardian who participated in the information intervention program with their cat(s) and/or dog(s) in a small animal hospital, with a follow-up interview after 2 weeks.

RESULTS

The information prescription helped both the experienced Internet searchers and the less health literate guardians. The pet guardians were particularly appreciative of the advice on evaluating and using online health information. The higher guardian-pet bond, the more the participant used the tips to search online information. The information prescription helped the relationship with the veterinary professional through improved data gathering and perception of the professional-guardian partnership.

CONCLUSION

The model will assist both information professionals and animal health providers to better design and evaluate information interventions that support pet welfare.

Health psychology and climate change: time to address humanity's most existential crisis

Climate change is an ongoing and escalating health emergency. It threatens the health and wellbeing of billions of people, through extreme weather events, displacement, food insecurity, pathogenic diseases, societal destabilisation, and armed conflict. Climate change dwarfs all other challenges studied by health psychologists. The greenhouse gas emissions driving climate change disproportionately originate from the actions of wealthy populations in the Global North and are tied to excessive energy use and overconsumption driven by the pursuit of economic growth. Addressing this crisis requires significant societal transformations and individual behaviour change. Most of these changes will benefit not only the stability of the climate but will yield significant public health co-benefits. Because of their unique expertise and skills, health psychologists are urgently needed in crafting climate change mitigation responses. We propose specific ways in which health psychologists at all career stages can contribute, within the spheres of research, teaching, and policy making, and within organisations and as private citizens. As health psychologists, we cannot sit back and leave climate change to climate scientists. Climate change is a health emergency that results from human behaviour; hence it is in our power and responsibility to address it.

Mediators and moderators of the effects of a school-based intervention on adolescents' fruit and vegetable consumption: the HEIA study

OBJECTIVE

To examine whether targeted determinants mediated the effects of the HEalth In Adolescents (HEIA) intervention on fruit and vegetable (FV) consumption and explore if these mediating effects were moderated by sex, parental education or weight status.

DESIGN

Cluster-randomised controlled trial.

SETTING

The HEIA study (2007-2009) was a Norwegian 20-month multi-component school-based intervention to promote healthy weight development. FV consumption and targeted determinants were self-reported at baseline, mid-way (8 months) and post-intervention (20 months).

PARTICIPANTS

Adolescents (11-13-year-old) in twenty-five control schools (n 746) and twelve intervention schools (n 375).

RESULTS

At post-intervention, more adolescents in the intervention group compared with the control group had knowledge of the FV recommendations (OR: 1·4, 95 % CI 1·1, 1·9) and reported a decreased availability of vegetables at home (β: -0·1, 95 % CI -0·2, 0·0). Availability/accessibility of FV at home, availability of vegetables at dinner, taste preferences for different types of FV and knowledge of the FV recommendations were positively associated with the consumption of FV. However, none of the post-intervention determinants significantly mediated the intervention effects on FV consumption. Although no moderating influences by sex, parental education or weights status were observed on the mediating effects, exploratory analyses revealed significant moderations in the b-paths.

CONCLUSIONS

Since none of the targeted determinants could explain the increase in FV consumption, it remains unclear why the intervention was effective. Reporting on a wide range of mediators and moderators in school-based interventions is needed to reveal the pathways through which intervention effects are achieved.

Effects of a Culinary Boot Camp intervention on food/nutrition aptitudes and dietary intake of college students

OBJECTIVE

College is characterized by transition, students shifting from dependence to independence in numerous roles/responsibilities. Deficiencies in food/nutrition aptitudes and dietary intake exist, evidenced by declining physical well-being and poor eating patterns/practices within the population. Studies examining interventions to improve food/nutrition aptitudes and dietary intake among college students are limited. Participants/methods: A nutrition education program, Culinary Boot Camp (CBC), was developed and delivered to college students at a land-grant university. Online surveys assessed food/nutrition aptitudes and dietary intake pre-/post-/follow-up intervention. Results: Of 86 CBC participants, 71 pre-, 46 post-, and 20 follow-up surveys were completed. Several food/nutrition aptitudes improved (p ≤ 0.05), with greatest improvements in cooking skills/attitudes and healthy eating/grocery shopping self-efficacy (p < 0.01). Additionally, dietary intake of various micronutrients (vitamin C, magnesium, potassium) and fiber increased with statistical significance (p < 0.01). Conclusions: Results suggest CBC is an effective nutrition education program to improve food/nutrition aptitudes and dietary intake amomg college students.

ABC-training as a new intervention for hazardous alcohol drinking: Two proof-of-principle randomized pilot studies

BACKGROUND AND AIMS

ABC-training is a new intervention to encourage health behavior change that targets the automatic activation of adaptive beliefs (i.e. automatic inferences). The aim of this proof-of-principle study was to test the effectiveness of web-based ABC-training to change outcome expectancies of alcohol drinking in a sample of hazardous drinkers.

DESIGN

One exploratory and one confirmatory experiment with two between-subject conditions (online ABC- and control-training) and assessments at baseline and 1 week later (after three sessions of training).

SETTING

Participants recruited on Prolific Academic completed the web-based study.

PARTICIPANTS

Adults with self-reported hazardous alcohol drinking (Experiment 1: 193 adults, United Kingdom, age mean = 46.7 years; Experiment 2: 282 adults, different nationalities, age mean = 38.3 years).

INTERVENTION AND COMPARATOR

ABC-training involved completing an online task that required choosing personally relevant alternative behaviors to drinking alcohol in personally relevant antecedent contexts to attain personally important outcomes. Comparator was control-training, in which participants selected both the alternative behaviors and alcohol drinking an equal number of times. Training was completed at baseline, after 3 days and after 1 week.

MEASUREMENTS

Primary outcome was change in automatic and self-reported (negative/positive) outcome expectancies of alcohol drinking from baseline to after 1 week. Secondary outcomes were change in weekly alcohol consumption, self-efficacy, craving and motivation (and approach-alcohol associations in Experiment 1). Moderators were baseline outcome scores, motivation, age and alcohol dependency.

FINDINGS

Findings of this study are as follows: stronger increase in negative outcome expectancies after ABC- than control-training (Experiment 1: self-report, 95% confidence interval of difference scores (CIdiff ) = [0.04, Inf]; automatic, CIdiff  = [0.01, Inf]; Experiment 2: self-report, CIdiff  = [0.16, Inf]; automatic, CIdiff  = [0.002, Inf]). Stronger reduction in self-reported positive outcome expectancies after ABC- than control-training (Experiment 1: CIdiff  = [-Inf, -0.01]; Experiment 2: CIdiff  = [-Inf, -0.21]) but mixed findings on automatic positive outcome expectancies (Experiment 1: CIdiff  = [-Inf, 0.02]; Experiment 2: CIdiff  = [-Inf, -0.001]).

CONCLUSIONS

ABC-training may change outcome expectancies of alcohol consumption, but testing of clinically relevant effects in other samples is warranted.

Experimental Therapeutics: Opportunities and Challenges Stemming From the National Institute of Mental Health Workshop on Novel Target Discovery and Psychosocial Intervention Development

There has been slow progress in the development of interventions that prevent and/or reduce mental-health morbidity and mortality. The National Institute of Mental Health (NIMH) launched an experimental-therapeutics initiative with the goal of accelerating the development of effective interventions. The emphasis is on interventions designed to engage a target mechanism. A target mechanism is a process (e.g., behavioral, neurobiological) proposed to underlie change in a defined clinical endpoint and through change in which an intervention exerts its effect. This article is based on discussions from an NIMH workshop conducted in February 2020 and subsequent conversations among researchers using this approach. We discuss the components of an experimental-therapeutics approach such as clinical-outcome selection, target definition and measurement, intervention design and selection, and implementation of a team-science strategy. We emphasize the important contributions of different constituencies (e.g., patients, caregivers, providers) in deriving hypotheses about novel target mechanisms. We highlight strategies for target-mechanism identification using published and hypothetical examples. We consider the decision-making dilemmas that arise with different patterns of results in purported mechanisms and clinical outcomes. We end with considerations of the practical challenges of this approach and the implications for future directions of this initiative.

Exploring correlates of physical activity behaviour in UK children and their inter-relationships using a multidisciplinary approach: A concept mapping study

It is still unknown which correlates of physical activity behaviour (PAB) may be effective and how they may influence PAB in UK children. The objective of the current study was to generate a conceptual analysis of the correlates of PAB in UK children (5-12 years) using the input of researchers in the field of physical activity (PA experts; PAE) and other fields (non-PA experts; non-PAE). A concept mapping approach was used to identify potential (new) correlates of PAB in children, assess their importance based on rating of potential modifiability and effect, and generate a concept map depicting the associations between them. In the first (brainstorming) stage (n = 32 experts) yielded 93 correlates, including 14 new correlates not identified in previous reviews. In the second (rating and sorting) stage (n = 26 experts), 32 correlates were rated as important and a four-cluster concept map was generated including themes related to Society/community, Home/social setting, Personal/social setting and Psychological/emotional correlates. Two additional concept maps were generated for PAE and non-PAE. From expert opinion, we identified new correlates of PAB that warrant further research and we highlight the need to consider the interaction between intrapersonal and external correlates when designing interventions to promote PA in UK children.

Demand of and Access to Health Messages Through Mass Media in the Rural Community of Eastern Ethiopia: A Mixed Method Study

Background

The demand for health-related information has increased dramatically in recent years. Media is crucial in reaching health messages to audiences, especially those who are distant and rural. Therefore, the study aimed to assess demands, access, and factors associated with access to health messages through mass media in the rural community of Kersa District of East Hararghe, Eastern Ethiopia.

Methods

A mixed-methods study was conducted from October 15 to November 20, 2020. A quantitative cross-sectional and a qualitative phenomenological study design were applied. A total of 578 participants were included by using a systematic sampling technique. Collected data were entered into Epidata version 3.1 and analyzed using SPSS version 22.0. A multivariate logistic regression analysis model was used and reported using an adjusted odds ratio (AOR) with a 95% confidence interval (CI). Statistical significance was set at p <0.05. For qualitative, six-focused group discussions (FGDs) were used and then analyzed thematically.

Results

Overall, the demand of and access to health messages through mass media was 32.5% (95% CI=28.5-34.2%) and 26.6% (95% CI=24.6-28.7%), respectively. Factors such as having electric services (AOR=2.36, 95% CI=2.13-5.41), having a mobile phone (AOR=4.56, 95% CI=4.32-8.73), exposure to TV (AOR=4.73, 95% CI=1.03-11.62), and exposure to social media and printed media (AOR=5.24, 95% CI=1.07-15.63), a preference for programs such as news, current affairs, entertainment, health and educational were 2.37, 9.47, 4.75 and 7.55 times more likely to access health messages (AOR=2.37, 95% CI=1.00-5.61; AOR=9.47, 95% CI=3.54-25.34; AOR=4.75, 95% CI=1.23-18.38; and AOR=7.55, 95% CI=3.12-8.66, respectively). Qualitative findings, participants demand for health messages from health workers, radio, and the main source for accessing the message was the radio.

Conclusion

Approximately one in every three and one in every four rural communities in the study area had demand, and access to health messages through mass media, respectively. As a result, all stakeholders should emphasize and strengthen expanding methods of reaching health messages using mass media.

Which Intervention Strategies Promote the Adoption and Maintenance of Physical Activity? Evidence From Behavioral Trials With Cancer Survivors

BACKGROUND/PURPOSE

We address four questions about interventions to promote physical activity in cancer survivors: (a) How often is both the adoption and maintenance of behavior change tested in trials? (b) How often do interventions generate adoption-plus-maintenance of behavior change? (c) Are intervention strategies specifically geared at promoting maintenance of behavior change deployed in trials? and (d) Which intervention strategies distinguish trials that promote both the adoption and maintenance of physical activity from trials that promote adoption-only or generate no behavioral changes?

METHODS

Computerized literature searches identified 206 reports of randomized trials that measured physical activity in the wake of the intervention.

RESULTS

Only 51 reports (24%) measured both behavioral adoption (postintervention) and behavioral maintenance (≥3 months follow-up). The 51 reports included 58 tests of interventions; 22% of tests observed both adoption and maintenance of physical activity, 26% reported adoption-only, and 52% found no change in behavior. Change techniques designed to promote behavioral maintenance were used much less frequently than adoption techniques or adoption and maintenance techniques. Interventions that aimed to improve quality of life, used supervised exercise sessions, were undertaken in community centers, and deployed fewer behavior change techniques were associated with adoption-plus-maintenance of physical activity in cancer survivors.

CONCLUSIONS

The present findings offer new insights into the adoption and maintenance of physical activity and highlight the need to routinely assess these forms of behavior change in future trials. More extensive testing of intervention strategies specifically geared at maintenance of behavior change is warranted.

Maintaining long-term physical activity after cancer: a conceptual framework to inform intervention development

PURPOSE

This paper describes a conceptual framework of maintenance of physical activity (PA) and its application to future intervention design.

METHODS

Evidence from systematic literature reviews and in-depth (N = 27) qualitative interviews with individuals with cancer were used to develop a conceptual framework of long-term physical activity behaviour. Determinants of long-term PA were listed and linked with domains of the Theoretical Domains Framework which in turn were linked to associated behaviour change techniques (BCTs) and finally to proposed mechanisms of action (MoA).

RESULTS

The conceptual framework is presented within the context of non-modifiable contextual factors (such as demographic and material resources) and in the presence of learnt and adapted behavioural determinants of skills, competence and autonomous motivation that must be established as part of the initiation of physical activity behaviour. An inventory of 8 determinants of engagement in long-term PA after cancer was developed. Clusters of BCTs are presented along with proposed MoA which can be tested using mediation analysis in future trials.

CONCLUSION

Understanding the processes of PA maintenance after cancer and presentation of implementable and testable intervention components and mechanisms of action to promote continued PA can inform future intervention development.

IMPLICATIONS FOR CANCER SURVIVORS

This resource can act as a starting point for selection of intervention components for those developing future interventions. This will facilitate effective support of individuals affected by cancer to maintain PA for the long term.

The Transtheoretical model's processes of change in the heart of a physical activity intervention: A series of n-of-1

The objectives were a) to test whether a Processes of Change (POC)-personalized Transtheoretical model (TTM)-based intervention could increase physical activity (PA) among inactive adults, and b) to examine whether the intervention increased the level of TTM theoretical constructs. The following hypotheses were formulated: 1) PA levels will be significantly higher during and after the intervention in comparison to baseline measures; 2) the level of targeted POCs will increase during the intervention; 3) non targeted POCs will stay stable, and 4) self-efficacy and decisional balance levels will increase during the intervention. A series of N-of-1 with A (1 to 2-week)-B(10-week)-A'(2-week) design were conducted with 12 inactive adults. Behavioral counselors used behavior change techniques to target TTM constructs and supervise PA. Interventions were individualized based on the 5 POCs with the lowest pre-intervention level. Device-based and subjective PA along with TTM measures were collected weekly online. PA data were analyzed with piecewise linear models. A visual analysis was run to examine the TTM constructs. Device, self-reported and TTM data were available for five, seven and five participants, respectively. A significant self-reported PA increase for six participants was found during the phase B and A2. A significant device-measured PA increase was observed in two participants during the study. A substantial increase of targeted POC from baseline for all participants with available data was observed. This study provides the first evidence of behavioral and psychological effects of a POC-personalized TTM-based intervention in inactive adults.

An Experimental Therapeutics Focus on Novel Mechanistic Targets in Cognitive Behavioral Treatments: Introduction to the Special Section

This article introduces the special section, "An Experimental Therapeutics Focus on Novel Mechanistic Targets in Cognitive Behavioral Treatments." The purpose of this special section is to highlight research that follows the recommended Science of Behavior Change (SOBC) developmental progression for an experimental medicine approach to identifying and testing mechanisms of behavior change. Emphasis was placed on the earlier stage "pipeline" of investigations of novel mechanisms for behavior change: mechanisms that are undergoing the initial stages of validation. In this series, seven empirical articles are presented and are followed by an article detailing a checklist for reporting mechanistic research studies in order to improve communication of findings in the field. The final article in this series discusses the history, current status, and future directions for the SOBC approach to mechanistic science as viewed by National Institute of Health program officials.

Individual-Community Misalignment in Partisan Identity Predicts Distancing From Norms During the COVID-19 Pandemic

This study investigated whether misalignment between an individual and their community in partisan identity predicted psychological and behavioral distancing from local COVID-19 norms. A nationally representative sample of Republicans and Democrats provided longitudinal data in April (N = 3,492) and June 2020 (N = 2,649). Democrats in Republican communities reported especially heightened better-than-average estimates, perceiving themselves as more adherent to and approving of non-pharmaceutical interventions (NPI; e.g., mask wearing) than their community. Democrats'better-than-average estimates reflected high approval and behavior in Republican communities and substantial norm underestimation. Republicans in Democratic communities did not evidence worse-than-average estimates. In longitudinal models, injunctive norms only predicted NPI behavior when individual and community partisan identity were aligned. The strong personal approval-behavior association did not depend on misalignment; there were no effects of descriptive norms. Normative messages may have limited efficacy for a sizable subpopulation in politically polarized contexts, such as the COVID-19 pandemic.

Approach-Bias Retraining and Other Training Interventions as Add-On in the Treatment of AUD Patients

In the past two decades, a variety of cognitive training interventions have been developed to help people overcome their addictive behaviors. Conceptually, it is important to distinguish between programs in which reactions to addiction-relevant cues are trained (varieties of cognitive bias modification, CBM) and programs in which general abilities are trained such as working memory or mindfulness. CBM was first developed to study the hypothesized causal role in mental disorders: by directly manipulating the bias, it was investigated to what extent this influenced disorder-relevant behavior. In these proof-of-principle studies, the bias was temporarily modified in volunteers, either temporarily increased or decreased, with corresponding effects on behavior (e.g., beer consumption), in case the bias was successfully manipulated. In subsequent clinical randomized controlled trials (RCTs), training (away from the substance vs. sham training) was added to clinical treatment. These studies have demonstrated that CBM, as added to treatment, reduces relapse with a small effect of about 10% (similar effect size as for medication, with the strongest evidence for approach-bias modification). This has not been found for general ability training (e.g., working memory training), although effects on other psychological functions have been found (e.g., impulsivity). Mindfulness also has been found to help people overcome addictions, and different from CBM, also as stand-alone intervention. Research on (neuro-)cognitive mechanisms underlying approach-bias modification has pointed to a new perspective in which automatic inferences rather than associations are influenced by training, which has led to the development of a new variety of training: ABC training.

The Effects of Implicit Theories on Body Weight Information Avoidance

Regular self-weighing is associated with more effective weight control, yet many individuals avoid weight-related information. Implicit theories about weight, or perceptions of how malleable weight is, predict more effortful weight management and may also influence weight-related information avoidance. Participants (N = 209) were randomly assigned to read an article stressing an incremental theory of weight (i.e., weight is malleable), an article stressing an entity theory (i.e., weight is fixed), or to a control condition. We then examined their self-reported preference to avoid their body composition (i.e., body fat, weight, and muscle composition), their willingness to have their body composition measured during the lab visit, and their eating and exercise intentions. There were no notable differences across conditions, but higher self-reported incremental beliefs predicted less self-reported avoidance of body composition. The findings suggest that implicit theories may influence weight-related information avoidance, but a brief manipulation is not powerful enough to create meaningful change.

Realizing the Tobacco Endgame: Understanding and mobilizing public support for banning combustible cigarette sales in the United States

BACKGROUND

There is little research on public support for banning the sale and purchase of combustible cigarettes even though a ban is an essential step towards achieving the endgame for tobacco products.

PURPOSE

We report the first studies designed to (a) examine predictors of support for a ban (Study 1), and (b) test interventions to increase such support (Studies 2-4).

METHODS

In Study 1, current, former, and never smokers (N = 479) were randomized to conditions measuring their willingness to ban the sale of cigarettes vs. an unspecified product. Smokers were randomized to a persuasive communication in Study 2 and a paradoxical thinking intervention in Study 3 (Ns = 300 and 302, respectively). In Study 4 (N = 336), we randomized smokers to self-persuasion and issue-framing interventions.

RESULTS

Whereas nonsmokers were willing to ban the sale of both cigarettes and equivalent products, current and former smokers exempted cigarettes from a ban. Reactance to prohibition and perceived effectiveness predicted willingness to ban cigarette sales in all three smoking status groups (Study 1). Neither persuasive communication nor paradoxical thinking increased support for banning cigarette sales in Studies 2-3. However, self-persuasion and framing the ban as "protecting Americans from avoidable harm" both led to increased support for banning cigarette sales (Study 4).

CONCLUSIONS

Reactance and doubt about the effectiveness of banning the sale of cigarettes are key barriers to supporting a ban. Self-persuasion and issue framing may be effective means of mobilizing policy support among smokers. The present research offers new insights relevant to promoting the "Tobacco Endgame" and helps specify directions for future research on public support for health policies.

Beyond Individual Cognitions: Time for Intervention Science to Focus on Health Context and Audience

Intervention science faces a hazardous paradox: on the one hand, vulnerable populations (eg, patients, people from low socioeconomic background, older adults) are those for whom adoption of healthy behaviors is most urgent; on the other hand, behavior change models are less predictive, and interventions less successful, in these populations. This commentary presents 4 reasons that may explain this issue: (1) research mostly focuses on what causes behavior and how to change it, at the expense of investigating among whom and under what conditions models are valid; (2) models put an undue emphasis on individual cognitions; (3) most studies are not conducted on vulnerable populations; and (4) most researchers are from high-income countries. Several avenues are proposed to address this issue: (1) providing a central place to the context and audience in health behavior change modelization, through collaborations with researchers from other disciplines and countries, and with members of the targeted audience; (2) better reporting samples' sociodemographic characteristics and increasing samples' diversity; and (3) using more rigorous and innovative designs (eg, powered randomized controlled trials, N-of-1 trials, intensive longitudinal studies). In conclusion, it becomes urgent to change the way we do research: the social utility and credibility of intervention science depend on it.

Expectancies that Predict Cannabis Initiation in Response to Legalization

Background: Recent and prospective changes to nonmedical/recreational cannabis laws in the United States and abroad raise questions about how legalization may influence cannabis use behaviors. Objectives: In the current study, we examined links between legalization, context-specific likelihood of using cannabis, and cannabis expectancies using cross-sectional survey data from 121 college students who had never used or were abstaining from cannabis in a U.S. state where laws prohibit nonmedical cannabis. Results: We found that across scenarios, 61% of students reported they would be more likely to use cannabis if it were legal. Social/sexual facilitation expectancies predicted a higher likelihood of using cannabis after legalization in a social context. Relaxation/tension reduction expectancies predicted a higher likelihood of using in an anxiety relief context. Perceptual/cognitive enhancement expectancies predicted a higher likelihood of using in a pain relief context. Cognitive/behavioral impairment expectancies predicted a lower likelihood of using in social, pain relief, relaxation, and concert contexts. Global negative effects expectancies predicted a lower likelihood of using in relaxation and concert contexts. Conclusions: Our findings suggest that among college students who do not use cannabis, expectancies are linked to cannabis use likelihood in certain contexts if cannabis were legal. This work highlights cannabis expectancies and contexts as possible targets for evidence-based public health education and clinical prevention initiatives related to the potential increase in cannabis use associated with cannabis policy implementation. College students may benefit from initiatives that address cannabis expectancies and enhance harm reduction skills to help them effectively navigate contexts in which cannabis is available to them.

Activation Versus Change as a Principle Underlying Intervention Strategies to Promote Health Behaviors

BACKGROUND AND PURPOSE

Interventions are effective in promoting health behavior change to the extent that (a) intervention strategies modify targets (i.e., mechanisms of action), and (b) modifying targets leads to changes in behavior. To complement taxonomies that characterize the variety of strategies used in behavioral interventions, we outline a new principle that specifies how strategies modify targets and thereby promote behavior change. We distinguish two dimensions of targets-value (positive vs. negative) and accessibility (activation level)-and show that intervention strategies operate either by altering the value of what people think, feel, or want (target change) or by heightening the accessibility of behavior-related thoughts, feelings, and goals (target activation).

METHODS AND RESULTS

We review strategies designed to promote target activation and find that nudges, cue-reminders, goal priming, the question-behavior effect, and if-then planning are each effective in generating health behavior change, and that their effectiveness accrues from heightened accessibility of relevant targets. We also identify several other strategies that may operate, at least in part, via target activation (e.g., self-monitoring, message framing, anticipated regret inductions, and habits).

CONCLUSIONS

The Activation Vs. Change Principle (AVCP) offers a theoretically grounded and parsimonious means of distinguishing among intervention strategies. By focusing on how strategies modify targets, the AVCP can aid interventionists in deciding which intervention strategies to deploy and how to combine different strategies in behavioral trials. We outline a research agenda that could serve to further enhance the design and delivery of interventions to promote target activation.

Can a simple plan change a complex behavior? Implementation intentions in the context of water drinking

Underhydration has significant adverse physical and mental health effects, yet many people drink too little water. Implementation intentions have been found to effectively promote many health behaviors, but little is known about the processes underlying their effects in naturalistic settings, and whether they could improve water drinking. This mixed-methods study assessed the impact and potential underlying processes of using implementation intentions to increase self-reported water intake over a five-day follow-up. Ninety-five participants (Mage = 39, SD = 12) received an educational quiz to increase their water drinking motivation before being randomly assigned to the control or intervention group. Participants also completed a qualitative survey that assessed the processes underlying their attempts to increase water intake. Quantitative results suggested that most participants increased their average daily water intake regardless of group. Qualitative results indicated that implementation intention participants struggled with remembering and the perceived effort of preparation and drinking behaviors, which reduced the effect of planning on behavior. This study provides essential theoretical and methodological considerations for researchers studying implementation intentions, as the effects and mechanisms of implementation intentions in real-life situations may be more complex than previously assumed. For example, the results suggest that implementation intentions did not automatize remembering and performing the behavior in ways the current literature theorizes. Other kinds of interventions may be needed to improve the complex daily-life behaviour of water drinking.

Expanding the analysis of mechanisms of action in behavioral interventions: cognitive change versus cognitive activation

OBJECTIVE

To understand the mechanisms of action underlying behavioral interventions, researchers typically examine whether the treatment changes cognitions and whether changes in cognition predict behavior (cognitive change). This current research explores an alternative mechanism whereby the intervention increases the impact of pre-existing cognitions on behavior (cognitive activation). We tested whether cognitive change or cognitive activation explains the impact of cigarette pack messages on smoking restraint.

DESIGN

The research comprised a validation experiment (N = 135) and a 4-week RCT (N = 719) with smokers.

MAIN OUTCOME MEASURES

At both baseline and follow-up of the RCT, smokers self-reported threat appraisals, coping appraisals, and smoking restraint.

RESULTS

Intervention messages heightened the accessibility of threat appraisals compared to control messages (validation experiment). In the RCT, smoking restraint increased among intervention participants but not controls. Trial arm showed no corresponding change in threat or coping appraisals. However, trial arm interacted with baseline health cognitions such that synergies between threat appraisal components, and between threat appraisals and coping appraisals, predicted smoking restraint for intervention participants but not for controls.

CONCLUSION

Our findings support a cognitive activation process whereby health messages on cigarette packs increase the impact of pre-existing threat appraisals on smoking restraint.

Development and Validation of Physical Activity-Specific Rumination Scale for Children Through UK Children's Voice

Many physical activity (PA) interventions implemented to tackle the child obesity epidemic have shown limited effectiveness, possibly due to a lack of consideration of potential stress that accompanies behavior adaptation and the automatic perseverative cognition that exacerbates the stress (namely rumination). Purpose: The main aim of this paper is to develop and validate the PA-specific Rumination Scale for Children (PARSC) that assesses children's tendencies to engage in repeated negative thoughts about PA (Study 2). Items in the scale were derived from qualitative information about factors that inherently demotivates PA participation (intrinsic barriers) through the lived experience of UK children (Study 1). Methods: For Study 1, pedometry PA data were collected from 143 children (aged 6-10 years). Twenty-one focus groups were formed based on participants' year group, sex and PA level. For PARSC validation (Study 2), 382 children completed the questionnaire twice. Self-report PA, device-based PA, and avoidant coping were also assessed. Results: Study 1-Four overarching themes identified as intrinsic barriers were lack of competence, fear of negative experiences, external constraints and lacking a sense of purpose. Altogether, 10 higher order and lower order themes were used to construct PARSC items. Study 2-From Rasch analysis, PARSC possessed sound internal validity, internal consistency, and test-retest reliability. Self-report PA and avoidant coping were predictive of PA-specific rumination, but not device-based PA. Conclusion: PARSC is a useful tool to identify children ruminative about PA for whom interventions can be designed, with the intrinsic barriers considered, to promote PA behavior adaptation.

Linking measures to mechanisms of action: An expert opinion study

OBJECTIVE

This study sought to integrate the NIH Science of Behaviour Change (SOBC) measures repository comprising measures of putative mechanisms with mechanisms of action (MoA) identified by the Human Behaviour-Change Project (HBCP).

DESIGN

Participants were 30 international experts recruited from professional networks and societies. In three anonymous virtual rounds, experts established consensus on hypothesized links between 26 MoAs and 44 self-report measures.

METHODS

In Round 1, experts completed a survey rating agreement with 84 pre-identified measure-MoA links and suggested new links. In Round 2, experts discussed 10 links in an online forum, including pre-identified links with <50% agreement and new links suggested by 20-50% of experts. In Round 3, experts completed a survey rating all links eligible for discussion in Round 2.

RESULTS

Twenty-seven experts completed Round 1, 23 completed Round 2 and 18 completed Round 3. In Round 1, 82 of 84 pre-identified links reached >50% agreement and 14 new links were suggested by >50% of experts. In Round 2, experts discussed measure-MoA links and measurement quality. In Round 3, 71 of 96 links reached ≥50% agreement. A total of 167 links reached >50% expert agreement, 33 of which reached ≥90% agreement.

CONCLUSION

By identifying putative mechanisms (HBCP) for the 44 self-report measures (SOBC), this study advances the cumulation of scientific results and interoperability of resources to facilitate process research.

Rigorous theory-based intervention research is the bold action needed to address oral health disparities and inequities

The Consensus Statement about behavioral and social sciences in oral health encourages future research to draw on testable theories that specify causal pathways that reflect the complex nature of oral health. In this commentary, we amplify the importance of explicit and well-specified theory in oral health intervention research, acknowledging that problematic use of theory has limited its utility in developing effective public health interventions. Also, we affirm the need to focus on determinants of oral health-and health inequities-most likely to drive meaningful change, and to understand the causal pathways that connect drivers of change from the individual to the global level. We view theory-based, causal mechanisms research as a powerful approach to building successful public health interventions, and suggest resources to inspire such research, including exemplary studies, methodologies, and collaborative initiatives that facilitate strong theory-based public health research.

The Use of Biomarkers to Guide Precision Treatment for Tobacco Use

This review summarizes the evidence to date on the development of biomarkers for personalizing the pharmacological treatment of combustible tobacco use. First, the latest evidence on FDA-approved medications is considered, demonstrating that, while these medications offer real benefits, they do not contribute to smoking cessation in approximately two-thirds of cases. Second, the case for using biomarkers to guide tobacco treatment is made based on the potential to increase medication effectiveness and uptake and reduce side effects. Next, the FDA framework of biomarker development is presented along with the state of science on biomarkers for tobacco treatment, including a review of the nicotine metabolite ratio, electroencephalographic event-related potentials, and other biomarkers utilized for risk feedback. We conclude with a discussion of the challenges and opportunities for the translation of biomarkers to guide tobacco treatment and propose priorities for future research.

Barriers and facilitators influencing parental adherence to prevention strategies for deformational plagiocephaly: Results from a scoping review

BACKGROUND

Deformational plagiocephaly can be prevented in many healthy infants if strategies are implemented early after birth. However, despite efforts to disseminate accurate information, parental adherence to evidence-based prevention strategies is a challenge. To date, factors - barriers and facilitators - influencing parental adherence to strategies have yet to be identified in a comprehensive manner.

OBJECTIVES

This scoping review aims to identify and synthesize current evidence on barriers and facilitators impacting adherence of parents of newborns to deformational plagiocephaly prevention strategies.

METHODS

This review followed the Joanna Briggs Institute (JBI) process guidelines. Seven electronic (Cumulative Index to Nursing and Allied Health Literature (CINAHL), MEDLINE, SPORTDiscus, Academic Search Complete, AMED, PsychINFO and Scopus) and two grey literature (Health Systems Evidence and Grey Literature Report) databases were searched. Studies published between 2001 and 2022 were included. The deductive thematic data analysis used was guided by the Capability, Opportunity, Motivation Behavioral Model (COM-B) of health behaviour change.

RESULTS

From a total of 1172 articles, 15 met the eligibility criteria. All components of the COM-B framework were identified. Capability-psychological and opportunity-environmental factors dominated the literature, whereas capability-physical, motivation and, in particular, opportunity-social factors were understudied. The most often reported barriers were a lack of knowledge of deformational plagiocephaly and the associated prevention strategies, ambiguous or inconsistent messaging, intolerance of babies to prone positioning and a lack of time. The most frequently reported facilitators were an awareness of deformational plagiocephaly, postural asymmetry and prevention strategies, skill acquisition with practice, accurate convincing information, scheduled time and environmental organization to position the baby at home.

DISCUSSION

Recommendations focused on diffusing accurate and detailed information for parents. Our review also suggests a gap regarding the comprehensive identification of factors influencing parental adherence to deformational plagiocephaly prevention strategies. Further studies exploring comprehensive opportunity-social and motivation factors influencing parental adherence to deformational plagiocephaly prevention strategies are warranted to inform prevention programmes and foster better infant outcomes.

"A reinstilled hope that they can change": Facilitator perspectives on a self-care and health promotion peer group program for veterans

Introduction

This study assessed the relevance, value, and effectiveness of "Taking Charge of My Life and Health" (TCMLH), a patient wellbeing peer group program for U.S. veterans focused on empowering them to identify what really matters in their lives and to work toward health goals that align with their mission, aspirations, or purpose in life. The potential of TCMLH to empower veterans to engage in self-care behaviors, make health behavior changes, and participate in health care decision making is important, as veterans are more likely than the general population to suffer from multiple chronic conditions that require ongoing self-management.

Methods

We conducted individual semi-structured interviews with 19 TCMLH facilitators serving in eight U.S. Veteran's Health Administration medical centers. Data were analyzed using an inductive approach to identify salient themes in facilitators' experiences.

Results

Facilitators reported that TCMLH participants demonstrated positive attitude changes (e.g., greater confidence and hope) and behavior changes (e.g., making healthcare appointments and implementing self-care practices) by program completion. Further, findings show that mindful awareness practices, the peer group setting, Whole Health assessment tools, and goal setting tools were perceived as the most impactful program elements leading to positive health behavior change.

Conclusion

Overall, findings suggest that this non-clinical peer group program can enhance patient wellbeing, and that there are certain program elements of TCMLH that are driving key attitudinal and behavioral changes.

The role of taxation measures in the management of harmful products, services, and practices in Iran: a qualitative study

BACKGROUND AND AIM

Levying a tax on harmful products, services, and practices can affect consumer choices, effectively preventing diseases and reducing health care costs. The goal of this study was to investigate the role of taxation as a powerful financial tool in the management of harmful products, services, and practices to maintain and improve public health and preserve the financial sustainability of the health care system.

MATERIALS AND METHODS

This qualitative study was conducted in 2020-2021. In order to collect information for this study, semi-structured interviews were conducted. Using purposive and snowball sampling methods, 38 managers, policymakers, economists, and key experts were interviewed. Data were analyzed using the content analysis method. The transcribed interviews were further imported into MAXQDA for classification, and relevant codes were extracted.

FINDINGS

In this study, 6 main themes and 19 subthemes were labeled. The main themes included 1) objectives, effects, and requirements of the taxation of harmful products, services, and practices, 2) definition, instances, elasticity, and grading of harmful products, services, and practices, 3) Problems in controlling harmful products, services, and practices, 4) controlling harmful products, services, and practices, 5) traffic violations and accidents, and social harms, and 6) tax revenue use and the share of health care. The effects of taxing harmful products include reduced access to these products, reduced demand for harmful products, and the promotion of public health.

CONCLUSION

Harmful products, services, and practices have major health and financial implications for individuals, families, and society. To improve public health, the demand for these products and services can be controlled through taxation measures to push consumers toward less harmful alternatives.

Predicting physical distancing over time during COVID-19: testing an integrated model

Objective: We applied an integrated social cognition model to predict physical distancing behavior, a key COVID-19 preventive behavior, over a four-month period. Design: A three-wave longitudinal survey design. Methods: Australian and US residents (N = 601) completed self-report measures of social cognition constructs (attitude, subjective norm, moral norm, perceived behavioral control [PBC]), intention, habit, and physical distancing behavior on an initial occasion (T1) and on two further occasions one week (T2) and four months (T3) later. Results: A structural equation model revealed that subjective norm, moral norm, and PBC, were consistent predictors of physical distancing intention on all three occasions. Intention and habit at T1 and T2 predicted physical distancing behavior at T2 and T3, respectively. Intention at T2 mediated effects of subjective norm, moral norm, and PBC at T2 on physical distancing behavior at T3, and habit at T1 and T2 mediated effects of behavior at T1 and T2 on follow-up behavior at T2 and T3, respectively. Conclusion: Normative (subjective and moral norms) and capacity (PBC) constructs were consistent predictors of physical distancing intention, and intention and habit were consistent predictors of physical distancing behavior. Interventions promoting physical distancing should target change in normative and personal capacity beliefs, and habit.Supplemental data for this article is available online at https://doi.org/10.1080/08870446.2021.1968397 .

Improving Hand Hygiene Behavior Using a Novel Theory-Based Intervention During the COVID-19 Pandemic

BACKGROUND

Promoting the adoption of personal hygiene behaviors known to reduce the transmission of COVID-19, such as avoiding touching one's face with unwashed hands, is important for limiting the spread of infections.

PURPOSE

We aimed to test the efficacy of a theory-based intervention to promote the avoidance of touching one's face with unwashed hands to reduce the spread of COVID-19.

METHODS

We tested effects of an intervention employing imagery, persuasive communication, and planning techniques in two pre-registered studies adopting randomized controlled designs in samples of Australian (N = 254; Study 1) and US (N = 245; Study 2) residents. Participants were randomly assigned to theory-based intervention or education-only conditions (Study 1), or to theory-based intervention, education-only, and no-intervention control conditions (Study 2). The intervention was delivered online and participants completed measures of behavior and theory-based social cognition constructs pre-intervention and one-week postintervention.

RESULTS

Mixed-model ANOVAs revealed a significant increase in avoidance of touching the face with unwashed hands from pre-intervention to follow-up irrespective of intervention condition in both studies, but no significant condition effects. Exploratory analyses revealed significant effects of the theory-based intervention on behavior at follow-up in individuals with low pre-intervention risk perceptions in Study 2.

CONCLUSIONS

Results indicate high adoption of avoiding touching one's face with unwashed hands, with behavior increasing over time independent of the intervention. Future research should confirm risk perceptions as a moderator of the effect theory-based interventions on infection-prevention behaviors.

What are the acceptances and associated influences of hospice care in Mainland China? A national cross-sectional study

Background

China ranks 53^rd out of 81 countries in the Quality of Death Index for 2021. Although hospice care demand is increasing, the progress remains slow. It is of great significance to explore the acceptances and associated influencing factors of hospice care.

Methods

A cross-sectional survey by quota sampling was conducted in China from July 10^th to September 15^th, 2021. We collected demographic data and hospice care acceptance. A stepwise linear regression analysis was used.

Results

This survey contained 11,031 valid questionnaire results to investigate the hospice care acceptance. It was found that individuals with undergraduate or above (β = 0.04), more properties [2 (β = 0.02), 3 (β = 0.01)], and higher reimbursement types of medical insurance [employee health insurance and commercial health (β = 0.03), government insurance (β = 0.04)] had higher hospice acceptance willingness, while males (β = -0.02) were less willing to accept than females. Psychological conditions [mild anxiety (β = 0.03), moderate anxiety (β = 0.01), moderate stress (β = 0.05), and severe stress (β = 0.06)] also played an important role. The Self-Management Scale (SHMS) (β = 0.12), EuroQol Five Dimensions Questionnaire (EQ-5D) (β = 0.05), EuroQol Visual Analog Scale (EQ-VAS) (β = 0.21), Short-Form Family Health Scale (FHS-SF) (β = 0.12), higher scores of the Short-Form Health Literacy Instrument (HLS-SF12) (β = 0.16), and Perceived Social Support Scale (PSSS) (β = 0.10) also contributed. Gender subgroup showed that in the male group, age, highest educational level, marital status, number of properties, whether having children, psychological conditions, the SHMS, EQ-5D, EQ-VAS, HLS-SF12, and PSSS showed significant difference. Urban and rural subgroups showed that age, highest educational level, number of properties, whether having chronic disease or psychological conditions, the SHMS, EQ-VAS, HLS-SF12, and PSSS were contributing factors in rural areas.

Conclusion

The average score of acceptance of hospice care was 65.02 points. Gender, house, anxiety, pressure, social support, and health literacy were the main influencing factors on residents' attitudes.

Gastroenterologist and Patient Attitudes Toward Yoga as a Therapy for Irritable Bowel Syndrome: An Application of the Theory of Planned Behaviour

Objectives

To identify irritable bowel syndrome (IBS) patients' attitudes, subjective norms, perceived control and intention to practice yoga and gastroenterologists' attitudes and current yoga recommendations for their patients with IBS.

Methods

Gastroenterologists and IBS patients completed online surveys including Theory of Planned Behaviour (TPB) constructs. Among IBS patients, multiple linear regression determined the multivariate associations between TPB variables and intention to practice yoga while controlling for significant socio-demographic variables. Gastroenterologists were asked about their attitudes and current yoga recommendations for patients with IBS. Chi-square analyses examined associations between gastroenterologists' demographics and recommending yoga. Binomial logistic regression described associations between attitude variables and current yoga recommendations.

Results

For patients (n = 109), controllability (β = 0.5, P < 0.001), affective attitude (β = 0.4, P < 0.05) and self-efficacy (β = 0.3, P < 0.05) were significantly associated with intention to do yoga in the regression model. TPB variables explained 34% of the variance in patients' intentions to practice yoga. The binomial regression analysis revealed that gastroenterologists (n = 79) who have confidence in recommending yoga (39%) were seven times more likely to recommend it (odds ratio = 7.3, P = 0.002) and those who agreed yoga improves IBS symptom severity (54%) were 10 times more likely to recommend yoga (odds ratio = 10.1, P < 0.001). Most (86%) wanted more evidence to support efficacy of yoga for IBS and 44% asked for more knowledge on how to refer a patient.

Conclusion

Controllability, affective attitude and self-efficacy predicted IBS patients' intentions to practice yoga. Although gastroenterologists believed yoga is safe and beneficial for IBS patients, most do not recommend yoga due to lack of confidence and scientific evidence.

Evaluating behavior change factors over time for a simple vs. complex health behavior

Background

Researchers are working to identify dynamic factors involved in the shift from behavioral initiation to maintenance-factors which may depend on behavioral complexity. We test hypotheses regarding changes in factors involved in behavioral initiation and maintenance and their relationships to behavioral frequency over time, for a simple (taking a supplement) vs. complex (exercise) behavior.

Methods

Data are secondary analyses from a larger RCT, in which young adult women, new to both behaviors, were randomly assigned to take daily calcium (N = 161) or to go for a daily, brisk walk (N = 171), for 4-weeks. Factors (intentions, self-efficacy, intrinsic motivation, self-identity, habit strength) were measured weekly. Multi-level modeling evaluated their change over time. Bivariate correlations and multiple regression determined the relationships between factors and the subsequent-week behavioral frequency (self-report and objective).

Finding

Results were partly in-line with expectations, in that individuals' intentions and self-efficacy predicted initial behavioral engagement for both behaviors, and habit strength increased for both behaviors, becoming a significant predictor of behavioral frequency in later weeks of the study in some analyses. However, results depended on whether the outcome was self-reported or objectively measured and whether analyses were bivariate or multivariate (regression).

Discussion

The factors theorized to play a role in behavioral maintenance (intrinsic motivation, self-identity, and habit strength) started to develop, but only habit strength predicted behavioral frequency by study-end, for both behaviors. Differences in initiation and maintenance between behaviors of differing complexity may not be as stark as theorized, but longer follow-up times are required to evaluate maintenance factors.

Intention to Pay for Vaccination and Influencing Factors of General Residents: A National Cross-Sectional Study

BACKGROUND

As an important part of the promotion of immunization programs and the suppression of infectious diseases, paid vaccines can prevent a variety of diseases and meet the needs of different populations. However, few studies focus on the public's intention to pay for vaccination.

METHODS

The survey was conducted from 10 July to 15 September 2021, adopting a cross-sectional survey in China. We used a multi-stage sampling strategy to recruit participators from 120 cities. Participants filled out questions which assessed their intentions to pay for vaccination. A linear regression analysis was given to identify the predictors associated with the subjects' attitudes.

RESULTS

There were 11,031 residents who finished our questionnaire. Chinese residents' intention to receive paid vaccines scored 74.5 points. Residents who were male (β = -0.03) and older (30-44 (β = -0.03) or 45-59 (β = -0.06) or ≥60 (β = -0.08)), living alone (β = -0.03), who had moderate to severe anxiety (β = -0.03) or severe anxiety (β = -0.03) were more likely to refuse vaccination, while those who lived in Western China (β = 0.03) who had higher PSSS scores and HLS-SF12 index might acquire the intention to pay for vaccination.

CONCLUSIONS

The study found that gender, age, region, living alone, anxiety, social support, and health literacy were the main influencing factors of residents' attitudes. Governments and health institutions should take targeted measures to improve the health literacy and mental health of the population in order to facilitate the implementation of vaccination withdrawal and immunization policies.
