Feasibility and Acceptability of a Peer Training Program to Deliver a Theory-Based Physical Activity Behavior Change Intervention to Inactive People Living With and Beyond Cancer: A Mixed Methods Study

Theory-based physical activity (PA) interventions include PA promotion strategies that can be delivered by exercise professionals, friends, family and peers. Peer-delivery presents a valuable opportunity for community implementation. Few peer-led PA interventions for people living with and beyond cancer (LWBC) report the feasibility of their peer mentor training methods. The purpose of this study was to assess the feasibility and acceptability of a peer mentor training program to deliver a behavioural PA intervention to inactive people LWBC using a mixed methods approach. Peer mentors (active people LWBC [≥90 min/week of PA]) participated in an online training program. Weeks 1 to 4 (Phase I) included knowledge and skill development (1-hour online module and 2-hour live workshop weekly). The Assessment phase (Phase II) explored peer mentor readiness (≥80% on a knowledge quiz and ≥3/5 points [Satisfactory] on a mock role play). Feasibility was assessed using enrollment rates, retention rates, adherence, and semi-structured interviews. Acceptability was measured using a satisfaction questionnaire assessing level of agreement with several statements about training program components. Peer mentors (<em>N </em>= 14; M<sub>age</sub> = 65.4 ± 10.7 years) were diagnosed with primarily prostate (57.1%) or breast (21.4%) cancer. Enrollment and retention rates were 73.7% and 92.9%, respectively. Workshops and online modules had 100% and 87.5% adherence rates, respectively. Majority of peer mentors met readiness criteria for the knowledge quiz (92.3%) and mock role play (84.6%) on their first attempt, with 92.3% delivering the follow-up peer-led PA intervention. Peer mentor satisfaction scores ranged from 3.9 to 4.6 out of 5. Interviews generated themes around overall impressions, feedback on timing, structure, and content of the training program and mock role play, and peer mentor preparedness. Structured training for delivering peer-led PA interventions show promise; however, individualized support may be needed for some people LWBC to strengthen mentorship knowledge and skills.

Persuasive software features as antecedents to perceived compliance within physical activity behavior change support systems

ABSTRACT Although behavior change support systems (BCSS) have the potential to improve compliance using persuasive software features, there is a dearth of empirical evidence on how these features impact perceived compliance. This study aimed to investigate how and to what extent the persuasiv systems design (PSD) principles in physical activity BCSS influence perceived compliance. Quantitative data from 403 participants (165 users and 238 prospective users of BCSS designed for PA) was analyzed using partial least squares structural equation modeling. Results revealed differences in how the PSD principles impact perceived compliance between users and prospective users. Perceptions of dialogue support, credibility support, and social support were more relevant to prospective users than to users. Thus, designers should pay more attention to these principles to attract and engage prospective users of BCSS. Conversely, primary task support was more relevant to users than to prospective users. This indicates that once prospective users transition to active users, the focus should shift towards providing persuasive features that facilitate the performance of the primary task. These findings underscore the importance of developing intelligent BCSS that can adapt to the evolving needs and preferences of users at different stages of their interactions with a system.

Willingness of Women at Increased Risk of Breast Cancer to Participate in Prevention Trials.

The factors affecting women's willingness to participate (WTP) in breast cancer (BC) prevention trials are poorly understood. This study aimed to identify the characteristics of interventions associated with a higher WTP among high BC risk women. Women who self-identified as being at an increased risk of BC were recruited to a cross-sectional study of WTP in BC prevention trials. Responses were dichotomized into more willing (a lot and moderately) and less willing (some, a little, and not at all), and responses were compared by patient characteristics and intervention type. Of 143 participants, 81.2% (116) completed ≥30% of a Likert-type scale questionnaire on WTP in various intervention types for BC prevention. Overall, WTP in BC prevention studies was high, with 82.7% more willing, including 69.0% and 70.7%, respectively, for unspecified physical activity and dietary interventions. WTP differed significantly by the duration of diet-based and physical activity behavior change interventions: decreasing with 12- versus 3-month diet-based interventions (P < .0001) and decreasing for 1 hour versus 30 minutes of low-intensity exercise/day (P < .0001). For interventions involving medication, only 18.1% expressed being more willing to participate, and WTP decreased significantly when side effects were presented. WTP was influenced by BC risk gene mutation status, with WTP among gene carriers higher compared with nongene carriers (52.6% v 30.2%, P = .018). WTP in BC prevention trials was the highest for women with known genetic risk and for interventions involving a behavior change. Medications with side effects had the lowest WTP. For behavior change, WTP was negatively influenced by intervention duration beyond a few months, indicating that individual perception of BC risk and inconvenience strongly influence WTP.

Changes in physical activity and sedentary behavior during COVID-19 pandemic restrictions in Germany

Abstract Background During the COVID-19 pandemic’s first wave, mobility restrictions and protective measures have impacted both public and private life. In Germany, the population was advised to stay home except for work, outdoor sport activities, and essential shopping. This study aims to evaluate how these measures affected physical activity and sedentary behavior, focusing on identifying the groups most affected. Methods In April and May 2020, we distributed a COVID-19-specific questionnaire to participants of the German National Cohort (NAKO). The questionnaire was specifically designed to assess changes in physical activity and sedentary behavior compared to pre-restriction levels, along with data on anxiety and depressive symptoms. Results Around 26 % of the 152,421 respondents reported increased sedentary time, and about 38 % reported reduced participation in sport activities compared to pre-restriction levels. Over one-third of those who previously met the WHO’s physical activity recommendation could not maintain it during the restrictions. There was also a notable decline in active transportation (M = - 0.12; 95% CI: -.126; -.117), whereas participants spent more time on recreational physical activities (M = 0.12; 95% CI: .117; .126). Based on multivariable linear and log-binomial regression models, we found that younger people were more affected by the restrictions than older adults. Factors such as transitioning to remote work, self-rated health, and depressive symptoms strongly correlated with changes in all physical activity domains, including sedentary behavior and adherence to physical activity guidelines. Conclusions The shift towards inactivity or low-intensity activities during the nationwide restrictions poses potential long-term health risks, highlighting the urgent need for public health policies to address the negative impact of COVID-19 restrictions on physical activity and sedentary behavior.

Physical Activity Behaviour and Motivation During and Following Pulmonary and Cardiac Rehabilitation: A Repeated Measures Study.

Exercise rehabilitation programmes are important for long-term health and wellbeing among people with cardiac and pulmonary diseases. Despite this, many people struggle to maintain their physical activity once rehabilitation ends. This repeated measures study tracked changes in physical activity behaviour and motivation during and after completing a community-based exercise rehabilitation programme. Cardiac and pulmonary exercise rehabilitation patients (N = 31) completed six once-monthly measures of physical activity (MET·min), self-determined motivation, intention, and habit strength for rehabilitation exercise (within rehabilitation sessions) and lifestyle physical activity (outside of rehabilitation sessions). Linear regression and random effects models with estimated marginal means were used to test for associations between physical activity motivation and behaviour and change during and post-rehabilitation. Overall physical activity decreased after rehabilitation (823 MET·min) despite patients becoming more self-determined for lifestyle physical activity during rehabilitation. More self-determined motivation, stronger intentions, and stronger habits were associated with more lifestyle physical activity behaviour. However, none of these motivation variables were significantly associated with rehabilitation exercise behaviour. Among community-based cardiac and pulmonary rehabilitation patients, physical activity levels decreased following exercise rehabilitation programmes. The findings revealed clear distinctions in the motivation of rehabilitation exercise compared to lifestyle physical activity. Exercise rehabilitation programmes might improve the longevity of outcomes by integrating approaches to enhance lifestyle physical activity beyond the clinic.

HabitWalk: A micro-randomized trial to understand and promote habit formation in physical activity.

Habit is a key psychological determinant for physical activity behavior change and maintenance. This study aims to deepen the understanding of habit formation in physical activity and identify promotion strategies. We examined the habit formation trajectory and its relationships with cue-behavior repetition (a cue-triggered 15-minute brisk walk) and unconditional physical activity (daily steps). We also tested whether the behavior change techniques (BCTs) 'commitment' and 'prompts and cues' promote habit, cue-behavior repetition, and daily steps within persons. This micro-randomized trial included a 7-day preparatory and a 105-day experimental phase delivered via the HabitWalk app. Participants (N = 24) had a 50% probability of receiving each BCT daily, leading to four conditions. Habit strength was assessed daily using the Self-Report Behavioral Automaticity Index, while cue-behavior repetition and steps were measured via an activity tracker. Person-specific growth functions indicated that habit strength trajectories were highly idiosyncratic. Multilevel models indicated a positive effect of cue-behavior repetition on habit strength, but not vice versa. The effect of habit strength on daily steps varied by the operationalization of cue-behavior repetition. Tentative findings suggest that commitment and prompts and cues are effective habit-promotion strategies when delivered together.

Personality and health behavior changes after pulmonary rehabilitation: A longitudinal observational study.

Pulmonary rehabilitation (PR) is the gold standard treatment for improving the health status of individuals with chronic respiratory diseases (CRD). However, to achieve lasting results, the adoption and maintenance of a physically active lifestyle are necessary. Unfortunately, the trajectories of change in physical activity (PA) and sedentary behavior (SB) following PR are marked by a high degree of heterogeneity between patients. This study aimed to better understand the factors underlying this variability by investigating the role played by the personality as defined by the five-factor model. Eighty eight CRD patients were assessed on personality upon PR admission (Time 1). PA and SB were assessed at Time 1 and 6 months post-PR (Time 2) using questionnaires. Multiple regression analyses revealed that "healthy neuroticism" is associated with an increase in PA 6 months after PR (β = .20, p < .05) independently of the PA at Time 1. A high level of neuroticism, when it is paired with a low level of conscientiousness, is related to an increase in SB 6 months after PR (β = -.20, p < .01), when the SB and exercise tolerance at Time 1 were controlled for. These findings highlight that investigating the interaction between personality traits is relevant to a better understanding of the interindividual differences in changes in PA and SB after PR in patients with CRD. The behavioral effects of PR could be improved if patients' personality traits were taken into account in the design of behavior-change interventions.

Mind the intention-behavior gap: a qualitative study of post-myocardial infarction patients’ beliefs and experiences with long-term supervised and self-monitored physical exercise

BackgroundMany post-myocardial infarction (MI) patients struggle with physical activity behavior change (BC) for life-long secondary prevention. There is limited knowledge about factors influencing long-term physical activity BC among post-MI patients. This qualitative study aimed to explore the beliefs and experiences related to post-MI patients’ physical activity BC process following a year’s participation in a supervised and self-monitored exercise program: the Norwegian Trial of Physical Exercise After MI (NorEx).MethodsWe conducted a qualitative study, performing in-depth semi-structured interviews with a randomly selected sample of NorEx participants when they were scheduled for cardiopulmonary exercise testing after one year of participation. Interviews were transcribed verbatim and the data was analyzed by applying reflexive thematic analysis.ResultsSeventeen participants (n = 4 female [24%]; median age, 61 years; median time since index MI, 4 years) were recruited and interviewed once. Analysis resulted in four main themes (nine sub-themes): (1) Personal responsibility to exercise (Exercise is safe, Health benefits, Habitual exercise); (2) Peer social support for a sense of safety and belonging (Social exercise, Supervision is preferred); (3) Research participation transformed exercise beliefs (High-intensity exercise is superior, Personal Activity Intelligence (PAI) promotes exercise adherence); and (4) Mind the intention-behavior gap (Initial anxiety, Lack of continued follow-up).ConclusionsSeveral participants reported that they were able to maintain exercise BC during a year’s participation in NorEx. Nevertheless, a perceived lack of continued and individualized follow-up made some participants struggle with motivation and self-regulation, leading to an intention-behavior gap. Therefore, our findings suggest there is a need for individualized and continued social support and supervision from health and exercise professionals to maintain long-term exercise BC for secondary prevention among post-MI patients.Trial registrationThe NorEx study has been registered at ClinicalTrials.gov (NCT04617639, registration date 2020-10-21).

Impact of a Clinical Placement on Pre-Professional Health Students Perceived Knowledge, Skills, and Confidence in the Delivery of Behaviour Change and Physical Activity Support

Background: Clinical placements may provide an appropriate setting for health professional students to learn and apply skills for supporting clients to improve their physical activity. Methods: A mixed methods study was conducted with pre-professional health students completing clinical placement at one of two interprofessional community clinics. Surveys assessed student self-reported perceived skills, knowledge, and confidence for behaviour change and physical activity support pre- and post-placement (unmatched n=40). Interviews were conducted with students (n=18) and clinical educators (n=4). Change in student knowledge, skills, and confidence were assessed using non-parametric tests; qualitative data underwent inductive thematic analysis. Results: Post-placement, unmatched participants perceived knowledge and understanding (p = 0.017), skills (p = 0.001), and confidence (p = 0.004) in behaviour change significantly increased. Perceived confidence in providing physical activity behavior change support for low-risk (p = 0.022) and complex conditions (p = 0.009) significantly improved. Qualitative data emphasised the importance of clinical educators and direct clinical experiences in preparing students for future practice. Conclusion: Student-facilitated interprofessional clinical placements may be important for developing pre-professional knowledge, skills, and confidence in delivering behaviour change and physical activity support. Further exploration of clinical placement opportunities for strengthening pre-professional health students training in physical activity promotion and behaviour change is recommended.

Decoding heterogeneity in data-driven self-monitoring adherence trajectories in digital lifestyle interventions for weight loss: a qualitative study

BackgroundData-driven trajectory modeling approaches have been used to identify participant subgroups with differing responses to digital lifestyle interventions. Identifying contributing factors to different participant subgroups can inform tailored strategies to early “rescue” intervention non-responders. Self-monitoring (SM) is a central mechanism in lifestyle interventions for driving behavior change and can serve as an early indicator for later intervention response. This qualitative study aimed to compare SM experiences between intervention response subgroups and to identify contributing factors to intervention response subgroups in a 6-month digital lifestyle intervention for adults with overweight or obesity.ResultsParticipants were middle-aged (52.9 ± 10.2 years), mostly female (65%), and of Hispanic ethnicity (55%). Four major themes with emerged from the thematic analysis: Acceptance towards SM Technologies, Perceived SM Benefits, Perceived SM Barriers, and Responses When Facing SM Barriers. Participants across both subgroups perceived SM as positive feedback, aiding in diet and physical activity behavior changes. Both groups cited individual and technical barriers to SM, including forgetfulness, the burdensome SM process, and inaccuracy. The Responder Group displayed positive problem-solving skills that helped them overcome the SM barriers. In contrast, some in the Non-responder Group felt discouraged from SM. Both subgroups found diet SM particularly challenging, especially due to technical issues such as the inaccurate food database, the time-consuming food entry process in the Fitbit app.ConclusionsOur study indicates that qualitative analysis is valuable for translating data-driven findings to actionable intervention improvement strategies. Our findings may inform the development of practical SM improvement strategies in future digital lifestyle interventions for weight loss. Notably, building problem solving skills emerge as a key approach to prevent potential non-responders from intervention disengagement.

Do Non-Clinical Services Help to Improve Functional Outcomes Among Young Adults With Mental Disorders? A Systematic Review.

Mental disorders during young adulthood can significantly impair functioning in daily activities. Non-clinical support services aim to improve functioning by helping people to build social and life skills, participate in education and employment and improve physical health. This study aims to examine and synthesise the evidence for non-clinical services on improving functional outcomes for young adults with mental disorders. A systematic search was undertaken to identify quantitative and qualitative studies reporting on a non-clinical service component (vocational support, peer support, youth development, lifestyle interventions, family and network support) and examining functional outcomes (e.g., outcomes focussed on work and education, life skills, relationships and healthy behaviours). Seventeen studies met inclusion criteria. Identified studies focussed on vocational support services (n = 9), lifestyle interventions (n = 6) and family and network support services (n = 2). No studies on peer-support services or youth development services were found. More than half of the vocational support service studies reported increased employment rates among young adults (n = 6). Studies focussing on lifestyle interventions included a combination of physical activity, nutrition education, health coaching and motivation and behaviour change. However, the measures of functioning used across studies were too varied to determine whether lifestyle interventions may be useful in improving functional outcomes for young adults. Further research is needed to understand the impact of non-clinical services on functioning. This evidence will provide pragmatic guidance for service planners to invest in supports and interventions that make a meaningful difference to the lives of young adults living with mental disorders.

Improving physical activity and screen time in Australian Outside School Hours Care: Study protocol.

Children's physical activity and screen time behaviours impact their physical health and well-being. In Australia, less than half of children meet daily physical activity recommendations and only one-third meet daily screen time recommendations. Nearly half a million Australian school children aged 5-12 attend Outside School Hours Care (OSHC) weekly, activities undertaken at OSHC play a key role in meeting these recommendations. Currently, physical activity and screen time practices in OSHC vary and lack policy guidance. The Activated OSHC program is a policy-based intervention that supports OSHC services to implement the physical activity and screen time guidelines. 192 OSHC services across Australia will be recruited. 96 services will be randomly allocated to receive the Activated OSHC program. OSHC coordinators will complete online surveys examining physical activity and screen time scheduling, cost, acceptability, and feasibility. Primary outcome; changes in the proportion of intervention and control services meeting OSHC sector physical activity and screen time guidelines, and secondary outcomes; changes in children's physical activity and screen time behaviours; changes in staff behaviour will be assessed using mixed-effects regression models. The aim of this study is to examine the impact of the Activated OSHC program on children's physical activity and screen time. Recent Australian research in Outside School Hours Care (OSHC) has identified significant inconsistency in practices related to physical activity and screen time, compounded by an absence of explicit policy guidance. The Activated OSHC program is a policy-based intervention that supports OSHC services to implement the Australian OSHC physical activity and screen time guidelines. This study will assess the implementation and effectiveness of the Activated OSHC program in an effectiveness-implementation hybrid type 2 trial design. Implementation of outside school hours care sector physical activity and screen time guidelines may improve children's physical activity and screen time behaviours.

Individualized pleasure-oriented exercise sessions, exercise frequency, and affective outcomes: a pragmatic randomized controlled trial

BackgroundAffective responses are increasingly recognized as potentially effective intervention targets that may facilitate exercise and physical activity behavior change. While emerging correlational evidence suggests that more pleasant affective responses are associated with higher participation and adherence, experimental evidence remains scarce. In light of this, we conducted a preregistered, pragmatic, single-blinded, superiority randomized controlled trial with two parallel groups, with the goal of determining the impact of an individualized exercise-intensity prescription targeting pleasure on exercise frequency.MethodsForty-seven non-regular exercisers were randomized into two groups. For both groups, the intervention consisted of three exercise sessions based on the Frequency-Intensity-Time-Type (FITT) principle. However, the experimental group also received an individualized intensity prescription based on prior assessment of preference for and tolerance of exercise intensity, as well as instructions emphasizing the promotion of pleasure as a basis for self-regulating exercise intensity. The primary outcome was gymnasium attendance over an eight-week follow-up period. Secondary outcomes were affective valence and arousal, post-exercise enjoyment, core affective exercise experiences, and anticipated and remembered affect.ResultsForty-six participants were retained for analysis (Mage = 32.00; SD = 8.62 years; 56.5% female). Compared to the control group, the experimental group exhibited 77% higher session attendance (14.35 vs. 8.13 sessions) over the eight-week follow-up period (group main effect p = 0.018, η2p = 0.120; Cohen’s d ranged from 0.28 to 0.91 during follow-up). Also, the experimental group reported higher levels of pleasure during the intervention sessions (for all group main effects, p < 0.001, η2p from 0.33 to 0.37) and higher levels of remembered pleasure (group main effect p = 0.021, η2p = 0.116) and anticipated pleasure (group main effect p = 0.022, η2p = 0.114). No harm was detected.ConclusionsThese results demonstrate the practicality and effectiveness of an intervention aimed at enhancing affective responses to exercise in improving short-term session attendance.Trial registrationClinicalTrial.gov NCT05416593.

Remote physical activity intervention to promote physical activity and health in adolescent girls (the HERizon project): a multi-arm, pilot randomised trial

BackgroundEngaging in physical activity (PA) during adolescence is beneficial for health and positive development. However, most adolescent girls have low PA levels, and there is a need for interventions outside of school hours. This pilot randomised controlled trial aimed to explore the preliminary effectiveness of three different remote PA interventions in increasing adolescent girls’ moderate-to- vigorous PA (MVPA), fitness and psychosocial outcomes.MethodsGirls living in the UK or Ireland, aged between 13 and 16 years old, who wished to increase their activity levels, were eligible for the study. Using a random number generator, participants (n = 153; 14.8y ± 1.4) were randomised into one of three 12-week intervention groups (i) PA programme, (ii) Behaviour change support, or (iii) Combined PA programme and Behaviour change support, or (iv) a Comparison group. Outcome measures included accelerometer and self-reported PA, physical fitness (cardiorespiratory fitness; 20 m shuttle run, muscular endurance; push up, muscular strength; long jump), and psychosocial assessments (perceived competence; body appreciation; self-esteem; behavioural regulation). Linear mixed models were used to analyse differences between each intervention arm and the comparison group immediately postintervention (12 weeks) and at follow up (3-months post-intervention), while adjusting for potential confounders.ResultsParticipation in the PA programme group was associated with higher perceived competence (0.6, 95% CI 0.1 to 1.2), identified regulation (0.7, 95% CI 0.2 to 1.1) and intrinsic motivation (0.9, 95% CI 0.2 to 1.6) at post-intervention. Participation in the Behaviour change group was associated with higher perceived competence at post-intervention (0.6, 95% CI 0.1 to 1.2), and higher push-up scores at the 3-month follow-up (4.0, 95% CI 0.0 to 7.0). Participation in the Combined group was also associated with higher perceived competence at post-intervention (0.8, 95% CI 0.2 to 1.4), and higher push-up scores at the 3-month follow-up (5.0, 95% CI 1.0 to 8.0). No other significant differences were found between the intervention arms and the comparison group.ConclusionResults suggest perceived competence increased across all intervention arms, while the PA programme group enhanced autonomous motivation in the short term. Intervention arms with behaviour change support appear most promising in improving muscular endurance. However, a larger scale trial is needed for a better understanding of between-group differences and the impact of intervention arms on MVPA and fitness, given the small sample size and short-term follow-up.

Physical activity and sedentary lifestyle: changes during confinement due to the COVID-19 pandemic according to age and non-communicable disease

Objective: To analyze the changes in physical activity (PA) and sedentary behavior during the COVID-19 pandemic, in the adult population according to age and non-communicable disease. Method. A cross-sectional study including n=1,334 subjects 18-55-year-old was carried out. The International Physical Activity Questionnaire (IPAQ-SF) was applied through an online survey to estimate the time (minutes/week) at each PA intensity and the total amount of METs/week before and during the COVID-19 confinement period. Results. The total METs/week [median (interquartile range, IQR)] decreased from 3657 (1977, 5466) to 1059 (396, 2225); sedentary behavior increased from 840 (0, 2100) to 2520 (1680, 4200) [p &lt;0.001]. PA decrease was mainly observed in those with a previously active lifestyle (≥3000 METs/week). Age was negatively related to this change. Conclusion. During the confinement, PA decreased, and sedentary behavior increased, mainly in subjects physically active before the confinement who were younger and regardless of suffering from non-communicable diseases. Keywords: guidelines physical activity, sedentary behavior, SARS-CoV-2, IPAQ.

Prevalence and Determinants of Changes in Physical Activity and Sedentary Behavior during and after the COVID-19 Pandemic: A Swedish Repeated Cross-Sectional Study.

Physical activity (PA) and sedentary behavior (SB) changed during the COVID-19 pandemic; hence, this study examined PA and SB at four time points between December 2019 and December 2022. The participants' PA decreased during the pandemic and did not recover afterwards. Among women, PA increased slightly in 2022 but not at all in men. From 2019 to 2020, SB increased and then decreased to near the pre-pandemic level in both sexes. Regarding age, PA decreased in the oldest age group (65-79 years) across all time points, while SB increased in all age groups during 2019-2020 and then returned close to pre-pandemic levels among the two middle age groups (30-64 years), but not among the youngest and oldest groups. Considering occupation, PA decreased from 2020 to December 2022 among retired and "other" participants, while SB decreased among nonmanual workers and retired participants. The regression models associated better self-reported health, male sex, and those born overseas with higher PA. Higher age, better self-reported health, poor education, and later survey time points were associated with lower SB. These findings highlight the need to return PA and SB to at least pre-pandemic levels and that subgroups may need different interventions.
