New parents' sleep, movement, health, and well-being across the postpartum period

OBJECTIVE

The aim of this study was to examine changes and the bi-directional relationship in sleep and movement, and health and well-being among new parents and differences by sex.

METHODS

This secondary data analysis included both conditions from a randomized control trial to improve new parents'physical activity [PA] and recruited couples. Parents (n = 181, 117 couples represented 31.5 ± 4.4 years, 51.3% women, 83.3% White) completed questionnaires on regular overnight sleep duration, PA, mental health (perceived stress), physical health (physical quality of life [PQoL]), and well-being (life satisfaction) at 2-, 4-, 6-, and 8-month postpartum. Random-intercept cross-lagged panel models were stratified by sex to examine changes in sleep and PA with health and well-being across time.

RESULTS

Sleep and stress were interrelated at different times for fathers (2 months), and mothers (8 months). Sleep and PQoL improved across time, with mothers reporting less sleep than fathers at 4 and 6 months. PQoL at 4 months was related to MVPA at 6-months. Life satisfaction and PA at 2 months was related to PA at 4 months.

CONCLUSION

Mothers and fathers experienced different sleep and stress trajectories. Mental health improved postpartum with early connections to PA. Supporting the 24-hour movement behavior cycle and mental health across the parenthood transition may benefit couples.

"It's what mothers do." A qualitative exploration of mothers' experiences of supporting their daughter to be physically active

OBJECTIVE

Girls are more at risk than boys of the non-communicable diseases associated with insufficient levels of physical activity (PA), therefore it is important to explore the reasons why girls maintain or cease to be physically active. Maternal support plays an important role in girl's PA, yet the factors influencing mothers' support of their PA have received limited exploration. In response, the aim of this study was to explore, mothers' experiences of supporting their daughters to be physically active and their perceptions of the factors that might influence these experiences.

METHOD

Semi-structured interviews were conducted with a purposive sample of mothers (n = 29) of girls (Mean age = 10.9 years; SD = 0.6). Reflexive Thematic Analysis was used to analyse the data, with themes mapped to the relevant domains of the Theoretical Domains Framework.

RESULTS

Themes highlighted how mothers described providing PA support as an inherent part of their parental role and how their role was influenced by their own PA identity. Mothers recognised that the type and amount of support they provided was impacted by the community setting in which they lived. Mothers acknowledged how the role of others (e.g., partners, grandparents, peers) added a layer of complexity to supporting their daughters to be active.

CONCLUSION

This study advances our understanding of maternal PA support behaviours recognising the complex interplay of individual, social and environmental factors. Additionally, the use of the Theoretical Domains Framework presents an in-depth behavioural diagnosis which can be used to inform future theory-based interventions to promote parent support of children's PA.

Increasing Health Behaviors and Psychological Measures with an Adapted Version of the ACCELERATION Program

BACKGROUND

Recent evidence highlights the importance of interventions tackling physical inactivity and unhealthy eating in lower-income countries. The purpose of this study was to examine the effectiveness of the Canadian ACCELERATION lifestyle program adapted to Brazilians. The main outcomes of the study were changes in the engagement in weekly moderate-to-vigorous physical activity (MVPA) and in the daily consumption of fruits/vegetables.

METHODS

The adapted intervention consisted of a 12-week quasi-randomized controlled trial delivered through email. The data from the original Canadian experimental group (CE, n = 194) and the two groups of Portuguese-speaking Brazilians living in Canada in the adapted program - Brazilian experimental (BE, n = 41) and Brazilian control (BC, n = 35) - were assessed at baseline and post-intervention. The data of the 270 participants were analyzed using two-way repeated measures factorial ANCOVA (group x time) for ratio variables and Chi-square and McNemar tests for the categorical variables.

RESULTS

The BE group had a significant increase in MVPA (mean difference, 95% CI: 86.3, 38.1-134.4 min/week) and fruits/vegetables intake (3.2, 1.4-5.1 servings/day) after the intervention (both p < 0.001). The proportion of participants engaging in ≥ 150 min of MVPA increased from 4.9% to 73.2%, while adoption of a healthy diet increased from 4.9% to 53.7% in the BE group (both p < 0.001). The CE group also improved on these variables (p < 0.05) with no difference vs the BE group (p > 0.05), whereas BC did not show changes (p > 0.05).

CONCLUSION

The Brazilian version of the ACCELERATION program effectively promoted positive health behavior changes in its participants and has the potential to contribute to the fight against risk factors for chronic diseases in Brazilians.

Parent Support for Physical Activity and Motor Skills During Early Childhood: A Mixed-Methods Application of the Multi-process Action Control Framework

BACKGROUND

Promoting physical activity (PA) and fundamental movement skills (FMS) in early childhood is necessary to address the high rates of inactivity in children. Parent support is a determinant of PA in children, however, parental intentions to support are not always translated into behavior resulting in an intention-behavior gap.

PURPOSE

Positioned within the multi-process action control (M-PAC) framework, this study used an explanatory concurrent mixed-methods design to explore parents' intentions and support of PA and FMS during early childhood.

METHODS

Parents (N=124) of children aged 3-4 years completed an online survey consisting of items assessing reflective (e.g., attitudes), regulatory (e.g., planning), and reflexive (e.g., habit) processes of M-PAC and intentions and support for child PA and FMS. A subset of parents (n=20) completed a semi-structured online interview guided by the M-PAC framework.

RESULTS

Significantly more parents intended to support PA (71%) compared with FMS (44%; p<0.001) and successfully translated intentions into action for PA (57%) compared with FMS (27%; p<0.001). Discriminant function analysis showed parent behavior profiles for PA and FMS support were associated with a combination of reflective, regulatory, and reflexive processes, however, these differed based on support behavior. Qualitative findings highlighted parents' differential views on PA and FMS support and contextualized the psychological processes associated with each.

CONCLUSIONS

Parent PA support interventions during early childhood should include strategies for supporting FMS. Interventions should prioritize fostering a combination of reflective, regulatory, and reflexive behaviors to translate intentions to support PA and FMS into behavior among parents of young children.

Exploring environmental cues to instigate physical movement in the workplace

Background

With the increase of sedentary jobs and the health risks associated with a sedentary lifestyle, finding novel methods to increase physical activity should be a priority. Environmental cues within the workplace can serve as cues to action for initiating light physical activity.

Aim

To qualitatively explore the environmental cues that can instigate light physical activity within an office workplace context. Identification of these cues can inform behaviour change programmes designed to promote habitual physical movement within the workplace.

Method

Purposive sampling was used to recruit full-time sedentary office workers who self-report as having a highly sedentary job. Interviews followed a semi-structured design and thematic analysis was used to explore environmental cues within commercial, home, and mixed office settings.

Results

Forty-three office workers were interviewed, 16 from a commercial office, 12 from a home office, and 15 with a flexible work arrangement whereby they worked from both a commercial and home office. The findings of this study indicate that across all three groups the main instigator of movement was influenced by office layout (e.g. getting up for beverages and taking bathroom breaks), social environment (e.g. informal and formal meetings), and taking active breaks, both job-related (e.g. printing and filing) and non-job-related (e.g. household chores).

Conclusions

These findings provide valuable insight for behaviour change programmes utilising environmental cues to inform habit-based interventions designed to instigate movement within the workplace.

Assessing Support for Policy Actions With Co-Benefits for Climate Change and Physical Activity in Canada

BACKGROUND

Calls to action addressing the interconnections between physical (in)activity and the climate crisis are increasing. The current study aimed to investigate public support for policy actions that potentially have co-benefits for physical activity promotion and climate change mitigation.

METHODS

In 2023, a survey through the Angus Reid Forum was completed by 2507 adults living in Canada. Binary logistic regressions were conducted. Separate models were created to reflect support or opposition to the 8 included policy items. Several covariates were included in the models including age, gender, political orientation, physical activity levels, income, urbanicity climate anxiety, and attitudes surrounding physical activity and climate change. The data were weighted to reflect the gender, age, and regional composition of the country.

RESULTS

Most individuals living in Canada strongly or moderately supported all actions (ranging from 71% to 85%). Meeting the physical activity guidelines, higher self-reported income, and scoring high on personal experience of climate change were associated with higher odds of supporting the policy actions related to climate actions.

CONCLUSIONS

Most adults living in Canada support policies that align with the recommended policy actions related to physical activity and climate change. National campaigns enhancing awareness and understanding of the bidirectional relationship between physical activity and climate change are warranted, and these should consider the consistent demographic differences (eg, gender, age, and political orientation) seen in public support for physical activity-related policies.

Testing the moderative role of automatic-reflective affect divergence in predicting physical activity

Dual process theories postulate that behaviour is the product of two distinct cognitive systems, the automatic and reflective, and that congruence/divergence between the two types of cognitions can influence the predictive strength of either system on behaviour. However, the congruence/divergence hypothesis has yet to experience strong empirical support. The aim of this study was to test a novel dual process model to determine the moderating effect of affect divergence on the relationship between automatic affective evaluations-affective judgements, and physical activity. A sample of 315 university students recruited from an undergraduate research pool completed the Affective Misattribution Procedure and Affective Exercise Experiences Questionnaire, followed by a measure of physical activity behaviour one week later. A path analysis revealed a significant moderation effect such that the predictive strength of affective judgements was stronger when participants' automatic affective evaluations and affective judgements were congruent. Findings support current dual process theory and contributes to calls for more interventions, such as evaluative conditioning that target automatic processes alongside consciously held beliefs.

Associations of physical activity and history of sports participation with subjective and objective measures of executive functioning in university students

This study examined how physical activity and history of sports participation affect subjective and objective executive functioning in university students. A total of 215 university students aged 18-25 (81% female) completed a virtual assessment of executive function. The correlates were age, sex, physical activity, and history of sports participation. Structural equation modeling was used to examine objective executive function using a three-factor model (shifting, updating, inhibition). The Executive Function Index (EFI) was used to measure subjective executive functioning, and linear regression was used to examine total EFI scores. Physical activity (b = 0.12, p < .01) was a significant correlate of subjective but not objective executive functioning. Male sex and history of sports participation were significantly positively related to the objective measure of inhibition (b = 0.64, p < .01; b = 0.18, p < .05). These findings suggest that subjective and objective measures of executive functioning should be differentiated when investigating their relationship with physical activity and history of sports participation.

Translating Physical Activity Intentions into Behavior: Reflective, Regulatory, and Reflexive Processes

The purpose of this article was to review predictors of the physical activity (PA) intention-behavior relationship. The review provides evidence for the hypothesis that reflective (consciously deliberated expectations of PA), regulatory (tactics used to enact intentions), and reflexive (stimulus-based associative motivation) processes represent independent determinants of translating PA intentions into action, yet differ in relative contribution across time and circumstance.

Re-assessing the social climate of physical (in)activity in Canada

Social-ecological models suggest that a strategy for increasing population physical activity participation is to reconstruct the "social climate" through changing social norms and beliefs about physical activity (PA). In this study, we assessed whether the PA social climate in Canada has changed over a five-year period after controlling for sociodemographic factors and PA levels. Replicating a survey administered in 2018, a sample of adults in Canada (n = 2,507) completed an online survey assessing social climate dimensions, including but not limited to descriptive and injunctive norms. Descriptive statistics were calculated, and binary logistic regressions were conducted to assess the associations of sociodemographic factors and year of the survey with social climate dimensions. Results suggest some social climate constructs are trending in a positive direction between 2018 and 2023. Physical inactivity was considered a serious public health concern by 49% of respondents, second to unhealthy diets (52%). Compared to those who participated in the 2018 survey, participants in 2023 were less likely to see others walking or wheeling in their neighbourhood (OR = 1.58, 95% CI: 1.41, 1.78), but more likely to see people exercising (OR = 0.82, 95% CI: 0.73, 0.92) and kids playing in their neighbourhood (OR = 0.75, 95% CI: 0.66, 0.85). No changes were reported between 2018 and 2023 in individuals' perceptions of whether physical inactivity is due to individual versus external factors (OR = 0.99, 95% CI: 0.87, 1.13). The findings of this work indicate a modest positive shift in some measured components of the social climate surrounding PA although attributing causes for these changes remain speculative.

Prioritizing a research agenda on built environments and physical activity: a twin panel Delphi consensus process with researchers and knowledge users

BACKGROUND

The growth of urban dwelling populations globally has led to rapid increases of research and policy initiatives addressing associations between the built environment and physical activity (PA). Given this rapid proliferation, it is important to identify priority areas and research questions for moving the field forward. The objective of this study was to identify and compare research priorities on the built environment and PA among researchers and knowledge users (e.g., policy makers, practitioners).

METHODS

Between September 2022 and April 2023, a three-round, modified Delphi survey was conducted among two independent panels of international researchers (n = 38) and knowledge users (n = 23) to identify similarities and differences in perceived research priorities on the built environment and PA and generate twin 'top 10' lists of the most important research needs.

RESULTS

From a broad range of self-identified issues, both panels ranked in common the most pressing research priorities including stronger study designs such as natural experiments, research that examines inequalities and inequities, establishing the cost effectiveness of interventions, safety and injuries related to engagement in active transportation (AT), and considerations for climate change and climate adaptation. Additional priorities identified by researchers included: implementation science, research that incorporates Indigenous perspectives, land-use policies, built environments that support active aging, and participatory research. Additional priorities identified by knowledge users included: built environments and PA among people living with disabilities and a need for national data on trip chaining, multi-modal travel, and non-work or school-related AT.

CONCLUSIONS

Five common research priorities between the two groups emerged, including (1) to better understand causality, (2) interactions with the natural environment, (3) economic evaluations, (4) social disparities, and (5) preventable AT-related injuries. The findings may help set directions for future research, interdisciplinary and intersectoral collaborations, and funding opportunities.

Increasing Physical Activity in Empty Nest and Retired Populations Online: A Randomized Feasibility Study

The onset of retirement and children leaving the family home may offer a "window of opportunity" for individuals to influence regular moderate- to vigorous-intensity physical activity; therefore, this study examines the feasibility of a moderate- to vigorous-intensity physical activity intervention among recently retired participants (RET) and parents (P) with children who recently left the family home. A total of 46 inactive RET and nine inactive P were randomized to a 10-week web intervention (n = RET = 25/P = 4) or waitlist control (n = RET = 21/P = 5). Intervention techniques followed the multiprocess action control framework. Enrollment (37.5% for P; 40% for RET), retention (89% for P; 83% for RET), and satisfaction were high. One hundred percent of intervention-sectioned participation increased moderate- to vigorous-intensity physical activity compared with 52% of controls; large effect size differences were observed for key multiprocess action control constructs. Participants were highly satisfied with the intervention; however, recruitment challenges of P support moving to a randomized controlled trial for only the RET group.

Supporting physical activity for mobility in older adults with mobility limitations (SuPA Mobility): study protocol for a randomized controlled trial

BACKGROUND

Limited mobility in older adults consistently predicts both morbidity and mortality. As individuals age, the rates of mobility disability increase from 1.0% in people aged 15-24 to 20.6% in adults over 65 years of age. Physical activity can effectively improve mobility in older adults, yet many older adults do not engage in sufficient physical activity. Evidence shows that increasing physical activity by 50 min of moderate intensity physical activity in sedentary older adults with mobility limitations can improve mobility and reduce the incidence of mobility disability. To maximize the healthy life span of older adults, it is necessary to find effective and efficient interventions that can be delivered widely to prevent mobility limitations, increase physical activity participation, and improve quality of life in older adults. We propose a randomized controlled trial to assess the effect of a physical activity health coaching intervention on mobility in older adults with mobility limitations.

METHODS

This randomized controlled trial among 290 (145 per group) community-dwelling older adults with mobility limitations, aged 70-89 years old, will compare the effect of a physical activity health coaching intervention versus a general healthy aging education program on mobility, as assessed with the Short Physical Performance Battery. The physical activity health coaching intervention will be delivered by exercise individuals who are trained in Brief Action Planning. The coaches will use evidence-based behavior change techniques including goal-setting, action planning, self-monitoring, and feedback to improve participation in physical activity by a known dose of 50 min per week. There will be a total of 9 health coaching or education sessions delivered over 26 weeks with a subsequent 26-week follow-up period, wherein both groups will receive the same duration and frequency of study visits and activities.

DISCUSSION

The consequences of limited mobility pose a significant burden on the quality of life of older adults. Our trial is novel in that it investigates implementing a dose of physical activity that is known to improve mobility in older adults utilizing a health coaching intervention.

Perceptions of self-monitoring dietary intake according to a plate-based approach: A qualitative study

Dietary self-monitoring is a behaviour change technique used to help elicit and sustain dietary changes over time. Current dietary self-monitoring tools focus primarily on itemizing foods and counting calories, which can be complex, time-intensive, and dependent on health literacy. Further, there are no dietary self-monitoring tools that conform to the plate-based approach of the 2019 Canada Food Guide (CFG), wherein the recommended proportions of three food groups are visually represented on a plate without specifying daily servings or portion sizes. This paper explored the perceptions of end-users (i.e., general public) and Registered Dietitians of iCANPlateTM-a dietary self-monitoring mobile application resembling the CFG. Qualitative data were collected through virtual focus groups. Focus group questions were based on the Capability, Opportunity, Motivation-Behaviour (COM-B) theoretical framework to explore perceptions of using the CFG and currently available dietary self-monitoring tools. The prototype iCANPlateTM (version 0.1) was presented to gain feedback on perceived barriers and facilitators of its use. Focus group discussions were audio recorded and verbatim transcribed. Trained researchers used thematic analysis to code and analyze the transcripts independently. Seven focus groups were conducted with Registered Dietitians (n = 44) and nine focus groups with members from the general public (n = 52). During the focus groups, participants mainly discussed the capabilities and opportunities required to use the current iteration of iCANPlateTM. Participants liked the simplicity of the application and its capacity to foster self-awareness of dietary behaviours rather than weight control or calorie counting. However, concerns were raised regarding iCANPlateTM's potential to improve adherence to dietary self-monitoring due to specific characteristics (i.e., insufficient classifications, difficulty in conceptualizing proportions, and lack of inclusivity). Overall, participants liked the simplicity of iCANPlateTM and its ability to promote self-awareness of dietary intakes, primarily through visual representation of foods on a plate as opposed to reliance on numerical values or serving sizes, were benefits of using the app. Findings from this study will be used to further develop the app with the goal of increasing adherence to plate-based dietary approaches.

Guidelines for assessment of affect-related constructs

Research on affect-related constructs as determinants of health behavior is increasing. The Affect and Health Behavior Framework (AHBF) provides a schematic structure to label, organize, and integrate affect-related constructs. To further facilitate research and theory development in health behavior science, the purpose of the present paper is to provide a critical review and guidelines for assessment of the affect-related constructs in the AHBF. The paper is organized based on the categories of constructs in the AHBF: Affective response to health behavior, incidental affect, affect processing, and affectively charged motivation. Future research should work toward parsing constructs where possible as well as identifying overlap. Researchers are advised to consider conceptual underpinnings and methodological nuances when assessing affect-related constructs in order to build a cumulative science of affective determinants of health behavior.

Dual processing approach to sedentary behavior and physical activity in the workplace

Regular physical activity is an important health promoting behavior. Yet, many adults live sedentary lifestyles, especially during their workday. The current study applies an extended theory of planned behavior model, incorporating affective attitudes and instrumental attitudes, along with habit, to predict limiting sedentary behavior and physical activity within an office environment. Theory of planned behavior constructs and habit were assessed with an online survey on a sample of 180 full-time office workers, with self-reported behavior assessed 1 week later (Mage = 25.97, SDage = 10.24; 44 males, 134 females, and 2 nonbinary). Model fit was indicated by BRMSEA (M = 0.057, SD = 0.023), B γ^ (M = 0.984, SD = 0.010) and BCFI (M = 0.959, SD = 0.026), accounting for 46.1% of variance in intention, 21.6% of variance in sedentary behavior, and 17.4% of variance in physical activity behavior. A Bayesian structural equation model revealed direct effects of instrumental attitudes and perceived behavioral control on intention to limit sedentary behavior, direct effects of intention and perceived behavioral control on limiting sedentary behavior, and direct effects of perceived behavioral control and habit on engaging in physical activity. The current study indicates intentions to be active in the office are primarily driven by beliefs about the benefits of activity and individuals' perceived level of control, rather than normative or affective beliefs. As behavior was predicted by both intention and habit, findings also indicate office-based activity is likely not always a consciously driven decision. These findings may have implications for improving activity levels in this highly sedentary population.

Child and youth physical activity throughout the COVID-19 pandemic: The changing role of the neighbourhood built and social environments

We explored associations between neighbourhood environments and children and youths' moderate-to-vigorous physical activity (MVPA) during three different waves of the COVID-19 pandemic: spring 2020, fall 2020 and spring 2021, using three nationally representative cross-sectional surveys. In wave 2, higher dwelling density was associated with lower odds of a child achieving higher-level MVPA, however, the odds were higher in neighbourhoods with higher density that also had better access to parks. With regard to the social environment, ethnic concentration (wave 3) and greater deprivation (waves 1 and 3) were associated with lower odds of a child achieving higher-level MVPA. Results indicate that built and social environments were differently associated with MVPA levels depending on pandemic restrictions.

Enhancing Physical and Psychosocial Health of Older Adults in Saudi Arabia through Walking: Comparison between Supervised Group-Based and Non-Supervised Individual-Based Walking

Walking is widely recognized as one of the most common and effective forms of physical activity, particularly for older adults. This study examined the comparative effects of two types of walking interventions, including supervised group-based intervention (SGBI) and non-supervised individual-based intervention (NSIBI), on frailty syndrome, cognitive functions or skills, and health-related quality of life among sedentary older Saudi individuals. A 15-week double-blinded, randomized controlled trial (RCT) including three groups (two were intervention groups while the other was the control group) was conducted among older adults who were inactive to examine the effect of different forms of walking interventions on frailty syndrome, cognitive functions, and health-related quality of life. A total of 107 participants, including 65 males and 42 females, were divided into three groups, which include SGBI, NSIBI, and the control group. Frailty syndrome was measured using the physical performance test (PPT), while cognitive function and health-related quality of life were assessed using the Mini-mental State Examination (MMSE) and the Short Form 36 (SF 36) health survey questionnaire. One-way repeated measures analysis of variance (ANOVA) and one-way analysis of covariance (ANCOVA) with the pre- and post-tests were performed for within- and between-group differences. while post-test data for the control group participants were absent due to the change in elderly center regulation, and they were excluded from the analysis. Hence, the comparison was stated only between the intervention groups. Both of the intervention groups (SGBI and NSIBI) showed significant within-subject differences in the Physical Function subscale of the health-related quality of life scale only, with F(1,20) = 23.03, p < 0.001, and F(1,18) = 27.22, p < 0.001, respectively. On the other hand, the Physical Performance Test revealed significant [F(2,51) = 9.21, p < 0.001] between-group differences in the post-test based on the baseline values. In addition, the average step count of older adults was increased from 4000 steps per session to around 7000 steps per session in the intervention group. The average heart rate of the NSIBI group did not show a visible change, and the resting heart rate of both groups showed a slightly declining trend throughout the intervention period. The walking intervention significantly increased participants' physical function, which is a component of health-related quality of life and physical performance (frailty level), along with average daily step counts for older adults in Saudi Arabia. Regular engagement in the recommended level of walking is strongly advisable for Saudi Arabian older adults to maintain their overall quality of life at this stage.

Prospective association between 24-hour movement behaviors and mental health among overweight/obese college students: a compositional data analysis approach

Background

24-h movement behaviors, including light physical activity (LPA), moderate-to-vigorous physical activity (MVPA), screen-based sedentary behavior (SSB), non-screen-based sedentary behavior (NSB) and sleep are crucial components affecting mental health. This study aimed to examine the associations of movement behaviors with mental health outcomes among overweight/obese college students using a compositional data analysis approach.

Methods

Using a prospective design, 437 Chinese college students (20.1 ± 1.7 years, 51.7% female) completed a two-wave online data collection, where demographics and movement behaviors (LPA, MVPA, SSB, NSB, sleep) were collected at baseline, while depression, anxiety and stress were measured at the 2-month follow-up (Apr-Jul 2022). Compositional data analyses were implemented using R.

Results

Depression, anxiety, and stress were negatively associated with time spent in MVPA and sleep (p < 0.001) and positively associated with time spent in SSB and NSB (p < 0.001). Reallocating 15 min to MVPA from LPA, SSB and NSB predicted improvements in depression (LPA: -0.234 unit; SSB: -0.375 unit; NSB: -0.249 unit), anxiety (LPA: -0.092 unit; SSB: -0.284 unit; NSB: -0.165 unit), and stress (LPA: -0.083 unit; SSB: -0.312 unit; NSB: -0.191 unit). For dose-response relationships of 5-55 min isotemporal substitution, when time was reallocated to MVPA from LPA, NSB, and SSB, the estimated detriments to mental health were larger in magnitude than the estimated benefits of time reallocation from MVPA to LPA, NSB, and SSB.

Conclusion

The findings emphasize the importance of participating in MVPA to improve mental health in overweight/obese college students during the post-COVID-19 era. The compositional analysis produced clear targets for the time allocation of these behaviors for future interventions and policymaking.

The intention-behaviour gap in physical activity: a systematic review and meta-analysis of the action control framework

OBJECTIVE

Intention is the proximal antecedent of physical activity in many popular psychological models. Despite the utility of these models, the discrepancy between intention and actual behaviour, known as the intention-behaviour gap, is a central topic of current basic and applied research. The purpose of this meta-analysis was to quantify intention-behaviour profiles and the intention-behaviour gap.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

Literature search was conducted in June 2022 and updated in February 2023 in five databases.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

Eligible studies included a measure of physical activity, an assessment of physical activity intention and the employment of the intention-behaviour relationship into profile quadrants. Only papers published in the English language and in peer-reviewed journals were considered. Screening was assisted by the artificial intelligence tool ASReview.

RESULTS

Twenty-five independent samples were selected from 22 articles including a total of N=29 600. Random-effects meta-analysis revealed that 26.0% of all participants were non-intenders not exceeding their intentions, 4.2% were non-intenders who exceeded their intentions, 33.0% were unsuccessful intenders and 38.7% were successful intenders. Based on the proportion of unsuccessful intenders to all intenders, the overall intention-behaviour gap was 47.6%.

CONCLUSION

The findings underscore that intention is a necessary, yet insufficient antecedent of physical activity for many. Successful translation of a positive intention into behaviour is nearly at chance. Incorporating mechanisms to overcome the intention-behaviour gap are recommended for clinical practice.

Affective Response During Real-World Physical Activity as an Intervention Mediator

Some people experience pleasure during physical activity, whereas it can be unpleasant for others. Modifying affective responses during physical activity in real-world situations may be an intervention strategy for increasing physical activity. This article follows an experimental medicine framework to summarize evidence identifying, assessing, and influencing affective response during real-world physical activity to inform interventions targeting this mediating mechanism.

The effects of walking on frailty, cognitive function and quality of life among inactive older adults in Saudi Arabia: a study protocol of randomized control trial by comparing supervised group-based intervention and non-supervised individual-based intervention

BACKGROUND

Kingdom of Saudi Arabia (KSA) demographics are also changing with the increase in life expectancy in the country and the rise in the number of older Saudi Arabians. Saudi Arabia has a higher rate of physically inactive people, and most of them are between the ages of 55-64. Walking is one of the most prevalent forms of physical activity in Saudi Arabia and the study showed that most people prefer walking for recreational and health benefits. Therefore, the purpose of the proposed study is to compare the effects of supervised group-based walking and non-supervised individual-based walking interventions on frailty, cognitive function and quality of life among inactive older adults in Saudi Arabia.

METHOD

This study will apply a three-group (2 intervention groups and 1 control group), double-blinded, randomized controlled trial (RCT) to examine the effect of different forms of walking interventions on Saudi Arabia older adults' frailty, cognitive function and quality of life immediately after a 16-week intervention, as well as the residual effects 12 weeks after completion of the interventions.

DISCUSSION

This study aims to determine whether supervised group walking and non-supervised individual walking lead to different effects. Given the limited evidence in the literature regarding Saudi Arabia older adults' physical fitness and health, it is worthwhile to explore the effect of walking, as well as the forms of walking on improving the overall physical fitness and psychological status of older adults in Saudi Arabia. The findings of the current study could also create awareness of the government and the general public in Saudi Arabia of the ageing problems and the effective ways of achieving better intervention results.

TRIAL REGISTRATION

The trial is registered at the ClinicalTrials.gov PRS (Trial ID: NCT05151575; Date of first posted: 12/07/2021).

Determinants of recreational screen time behavior following the COVID-19 pandemic among Canadian adults

The objectives of our study were to examine recreational screen time behavior before and 2 years following the COVID-19 pandemic lockdown, and explore whether components of the capability-opportunity-motivation-behavior (COM-B) model would predict changes in this recreational screen time behavior profile over the 2-year period. This cross-sectional, retrospective study was conducted in March 2022. Canadian adults (n = 977) completed an online survey that collected demographic information, current screen time behavior, screen time behavior prior to the pandemic, and beliefs about capability, opportunities, and motivation for limiting screen time based on the COM-B model. We found that post-pandemic recreational screen time (3.91 ± 2.85 h/day) was significantly higher than pre-pandemic levels (3.47 ± 2.50 h/day, p < 0.01). Three recreational screen time behavior profiles were identified based on the Canadian 24-Hour Movement Guidelines: (1) always met screen time guidelines (≤3 h/day) (47.8%; n = 454); (2) increased screen time (10.1%; n = 96); and (3) never met screen time guidelines (42%; n = 399). The overall discriminant function was found to be significant among the groups (Wilks' λ = 0.90; canonical r = 0.31, χ2 = (14) = 95.81, p < 0.001). The group that always met screen time guidelines had the highest levels of automatic motivation, reflective motivation, social opportunity, and psychological capabilities to limit screen time compared to other screen time profile groups. In conclusion, recreational screen time remains elevated post-pandemic. Addressing motivation (automatic and reflective), psychological capabilities, and social opportunities may be critical for future interventions aiming to limit recreational screen time.

Predictors of changes in running and smoking identity among individuals in the Run to Quit smoking cessation program

OBJECTIVES

Multiple health behaviour change is a viable strategy to promote health outcomes. An example is the use of running behaviour to support smoking cessation in the group-mediated Run to Quit program. On the basis that changes in running and smoking identity were related to changes in running and smoking behaviour among individuals in the Run to Quit program, the purpose of this study was to extend these findings by examining key predictors of change in both running and smoking identity.

METHODS

We analyzed data collected from 450 adult individuals (70.67% female, and 92.44% white) during the program evaluation of Run to Quit from 2016 to 2018. Participants completed assessments at week 1 (baseline), week 3 (mid-program), and week 10 (follow-up) of the program. Relevant predictor variables for change in identity were identified by drawing from theory (identity theory, identity control theory, physical activity self-definition model, social identity theory) and past research regarding exercise and smoking identity. Potential predictors of changes in running and smoking identity included changes in behaviour, self-efficacy, perceptions of the social environment (task and social cohesion, descriptive norms), as well as smoking identity and running identity, respectively. Two regression models, using residualized change scores (for each variable) and relative Pratt indices, were constructed for both running and smoking identity.

RESULTS

Changes in running self-efficacy, running frequency, and individual attractions to the group exercise tasks were significant and meaningful predictors of change in running identity, whereas changes in objectively measured smoking behaviour and running identity were significant and meaningful predictors of change in smoking identity.

CONCLUSION

Consistent with identity theories and past research, ensuring individuals develop a sense of efficacy and enjoy group exercise tasks both represent viable strategies to enhance exercise identity. Including an exercise component within smoking cessation programs may help individuals replace their existing smoking identity with a healthier exercise identity.

Use of Electronic Ecological Momentary Assessment Methodologies in Physical Activity, Sedentary Behavior, and Sleep Research in Young Adults: Systematic Review

BACKGROUND

Recent technological advances allow for the repeated sampling of real-time data in natural settings using electronic ecological momentary assessment (eEMA). These advances are particularly meaningful for investigating physical activity, sedentary behavior, and sleep in young adults who are in a critical life stage for the development of healthy lifestyle behaviors.

OBJECTIVE

This study aims to describe the use of eEMA methodologies in physical activity, sedentary behavior, and sleep research in young adults.

METHODS

The PubMed, CINAHL, PsycINFO, Embase, and Web of Science electronic databases were searched through August 2022. Inclusion criteria were use of eEMA; sample of young adults aged 18 to 25 years; at least 1 measurement of physical activity, sedentary behavior, or sleep; English language; and a peer-reviewed report of original research. Study reports were excluded if they were abstracts, protocols, or reviews. The risk of bias assessment was conducted using the National Heart, Lung, and Blood Institute's Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. Screening, data extraction, and risk of bias assessments were conducted by independent authors, with discrepancies resolved by consensus. Descriptive statistics and narrative synthesis were used to identify overarching patterns within the following categories guided by the Checklist for Reporting Ecological Momentary Assessments Studies: study characteristics, outcomes and measures, eEMA procedures, and compliance.

RESULTS

The search resulted in 1221 citations with a final sample of 37 reports describing 35 unique studies. Most reports (28/37, 76%) were published in the last 5 years (2017-2022), used observational designs (35/37, 95%), consisted of samples of college students or apprentices (28/35, 80%), and were conducted in the United States (22/37, 60%). The sample sizes ranged from 14 to 1584 young adults. Physical activity was measured more frequently (28/37, 76%) than sleep (16/37, 43%) or sedentary behavior (4/37, 11%). Of the 37 studies, 11 (30%) reports included 2 movement behaviors and no reports included 3 movement behaviors. eEMA was frequently used to measure potential correlates of movement behaviors, such as emotional states or feelings (25/37, 68%), cognitive processes (7/37, 19%), and contextual factors (9/37, 24%). There was wide variability in the implementation and reporting of eEMA procedures, measures, missing data, analysis, and compliance.

CONCLUSIONS

The use of eEMA methodologies in physical activity, sedentary behavior, and sleep research in young adults has greatly increased in recent years; however, reports continue to lack standardized reporting of features unique to the eEMA methodology. Additional areas in need of future research include the use of eEMA with more diverse populations and the incorporation of all 3 movement behaviors within a 24-hour period. The findings are intended to assist investigators in the design, implementation, and reporting of physical activity, sedentary behavior, and sleep research using eEMA in young adults.

The Physical Activity Regulation Scale: Development and validity testing

OBJECTIVE

Behavioral regulation tactics used to manage actions after the formation of a physical activity (PA) intention are common to many theories, yet comprehensive measures of PA regulation are scant.

PURPOSE

To develop a reliable instrument of PA regulation and test predictive validity and its capacity to mediate the intention-PA relationship.

METHOD

To achieve a pool of candidate items, we used the behavior change technique taxonomy as a template, followed by a critical literature review of PA regulation measures to extract exemplar items, and then concluded with a Delphi feedback method (N = 4). The main study included a sample representative of the Canadian adult population to explore and then confirm the construct and discriminant validity, and internal consistency reliability of the measure using two independent samples (N = 683 and N = 727). Finally, using a 2-week prospective design, the full sample was used to investigate test-retest reliability, and predictive validity of self-reported PA at Time 2.

RESULTS

Exploratory and confirmatory factor analyses resulted in a reliable 14-item, four-factor measure (internal consistencies > .80) of (a) proactive regulation, (b) reactive regulation, (c) social monitoring, and (d) self-monitoring, we named the Physical Activity Regulation Scale (PARS). The PARS factors explained 18% of PA at Time 2, and mediated the relationship between intention and PA.

CONCLUSION

While continued testing is needed, the initial evidence is supportive that the PARS may be a useful PA behavioral regulation measure to include for use within various theoretical models applied to understand PA. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Effects of older adults' social identification on psychological flourishing and exercise program adherence

BACKGROUND

With the onset of the COVID-19 pandemic, many exercise programs moved online. The purpose of this study was to examine the extent to which older adults' social identification with other exercise program members contributed to their psychological flourishing and exercise program adherence.

METHODS

The study represented a secondary analysis of data derived from the Seniors COVID-19 Pandemic and Exercise (SCOPE) Trial, in which older adults were randomized to a waitlist control condition or one of two online (personal v group) exercise programs. Only data from participants in the trial intervention conditions (N = 162; M_age = 73.52 years; SD = 5.61) were utilized in this secondary analysis. We assessed psychological flourishing and social identification at baseline and every two weeks, as well as program adherence over each 2-week block, for 12 weeks.

RESULTS

Based on stepwise multilevel modeling the results revealed that older adults' social identification with others in their respective exercise program had a direct effect on psychological flourishing (ΔR²_{Unique Marginal} = 0.063, p < .001) and program adherence (ΔR²_{Unique Marginal} = 0.014, p = .03).

CONCLUSIONS

The results highlight the value of bolstering older adults' social identification with others in an online exercise program to support adherence and well-being.

Correlates and participation in community-based exercise programming for cancer patients before and during COVID-19

PURPOSE

COVID-19 pandemic restrictions ceased the opportunity for face-to-face group exercise classes with at risk populations, such as cancer patients, forcing an adaptation to online exercise programming. The purpose of this study was to compare the attendance rates and correlates of face-to-face exercise programming pre-COVID-19 to online programming delivered during the first year of pandemic restrictions.

METHOD

The sample was comprised from 1189 patient records between 2018 and 2021. Data analysis was based around the three primary research questions: (i) whether the volume of attendance in online exercise programming differed from the previous face-to-face programming; (ii) whether there were any differences in attendee demographics between online and face-to-face classes; and (iii) whether there were specific correlates of online attendance that can inform future exercise programming.

RESULTS

Class attendance increased significantly when online exercise classes were introduced during the first year of the pandemic when compared to face-to-face attendance the prior years (p < .01). Multiple demographic findings were also observed including age, gender, and geographic differences.

CONCLUSION

While COVID-19 has effected the ability to deliver face-to-face exercise programs for cancer patients, online programming has proved a promising delivery model with greater geographical reach. The approach, however, has gender and age differences in program attendance so targeted programming to reach specific cancer patient demographics may need attention. These results add to the continuing research in the area of online exercise and online programming strategies offering an effective option for cancer patients to achieve targeted exercise prescription.

Piloting the Virtual PLAYshop Program: A Parent-Focused Physical Literacy Intervention for Early Childhood

The PLAYshop program is a parent-focused physical literacy intervention for early childhood. This single-group mixed-methods pilot study aimed to explore the feasibility of virtually delivering and assessing the PLAYshop program. The virtual PLAYshop program included a virtual workshop, resources/basic equipment, and two booster emails (3-week and 6-week follow-up). Data on 34 preschool-aged children (3-5 years) and their parents from Edmonton and Victoria, Canada, were collected via an online questionnaire, virtual assessment session, and interview at single or multiple time points (baseline, post-workshop, 2-month follow-up). Intraclass correlation coefficients (ICCs), paired t-tests, repeated measures ANOVAs, and thematic analyses were conducted. Regarding feasibility, most parents (≥94%) were satisfied/extremely satisfied with the virtual workshop and planned to continue physical literacy activities post-workshop. The virtual assessment protocol for children's fundamental movement skills (FMS; overhand throw, underhand throw, horizontal jump, hop, one-leg balance) was feasible, with high completion rates (>90%) and reliable scoring (ICC = 0.79-0.99). For positive changes in potential outcomes, a medium effect size was observed for children's hopping skills (d = 0.54), and large effect sizes were observed for several parental outcomes (partial η² = 0.20-0.54). The findings support the feasibility and potential positive outcomes of the virtual PLAYshop program. A larger randomized controlled efficacy trial is recommended.

Consistent exercise timing as a strategy to increase physical activity: A feasibility study

Introduction/Purpose

Observational research suggests that consistent exercise timing could be leveraged to promote moderate-to-vigorous physical activity (MVPA) among adults with obesity. However, the feasibility and acceptability of prescribed consistent exercise timing in a free-living setting is unknown. The purpose of this study was to assess the feasibility and acceptability of prescribed consistent exercise timing in a free-living setting among inactive adults with obesity (primary) and to compare MVPA timing prescriptions and characterize exercise barriers/facilitators (secondary).

Methods

Using a within-subjects design, inactive adults with obesity (n=15) were randomized in counterbalanced order to three 3-wk exercise timing conditions separated by 2-wk washout periods: 1) consistent morning, 2) consistent evening, and 3) choice timing (control). Feasibility was assessed using prespecified benchmarks. Acceptability and preferred timing were assessed with questionnaires post-intervention. Secondarily, exercise timing and MVPA were assessed via accelerometry and nightly surveys and barriers/facilitators were assessed with nightly surveys.

Results

All feasibility benchmarks were achieved (e.g., timing adherence = 69.9% via accelerometry and 87.4% via self-report (target: ≥60%)). Consistent exercise timing was acceptable (mean rating = 3.7 of 5 (target: ≥3.5)). Choice was the most popular prescription. There were medium- to large-sized effects (partial η2 of 0.09-0.16) of condition on MVPA; MVPA was higher during the morning and evening conditions versus choice condition. Facilitators were similar across conditions, while some barriers were time specific.

Conclusion

Prescribed exercise timing in a free-living setting appears feasible and acceptable. While choice timing was most preferred, consistent timing appeared most effective for increasing MVPA. Data warrant larger trials to test the efficacy and mechanisms of consistent exercise timing as a translational strategy for promoting MVPA. Pending findings from a fully powered randomized trial, practitioners interested in promoting MVPA among their patients or clients could consider encouraging exercise at a consistent time day-to-day.

Effects of Mobile-Based Financial Incentive Interventions for Adults at Risk of Developing Hypertension: Feasibility Randomized Controlled Trial

BACKGROUND

Hypertension is the leading modifiable risk factor for cardiovascular disease and mortality. Adopting lifestyle modifications, like increasing physical activity (PA), can be an effective strategy in blood pressure (BP) control, but many adults do not meet the PA guidelines. Financial incentive interventions have the power to increase PA levels but are often limited due to cost. Further, mobile health technologies can make these programs more scalable. There is a gap in the literature about the most feasible and effective financial incentive PA framework; thus, pay-per-minute (PPM) and self-funded investment incentive (SFII) frameworks were explored.

OBJECTIVE

The aims were to (1) determine the feasibility (recruitment, engagement, and acceptability) of an 8-week mobile-based PPM and SFII hypertension prevention PA program and (2) explore the effects of PPM and SFII interventions relative to a control on the PA levels, BP, and PA motivation.

METHODS

In total, 55 adults aged 40-65 years not meeting the Canadian PA guidelines were recruited from Facebook and randomized into the following groups: financial incentive groups, PPM or SFII, receiving up to CAD $20 each (at the time of writing: CAD $1=US $0.74), or a control group without financial incentive. PPM participants received CAD $0.02 for each minute of moderate-to-vigorous PA (MVPA) per week up to the PA guidelines and the SFII received CAD $2.50 for each week they met the PA guidelines. Feasibility outcome measures (recruitment, engagement, and acceptability) were assessed. Secondary outcomes included changes in PA outcomes (MVPA and daily steps) relative to baseline were compared among PPM, SFII, and control groups at 4 and 8 weeks using linear regressions. Changes in BP and relative autonomy index relative to baseline were compared among the groups at follow-up.

RESULTS

Participants were randomized to the PPM (n=19), SFII (n=18), or control (n=18) groups. The recruitment, retention rate, and engagement were 77%, 75%, and 65%, respectively. The intervention received overall positive feedback, with 90% of comments praising the intervention structure, financial incentive, and educational materials. Relative to the control at 4 weeks, the PPM and SFII arms increased their MVPA with medium effect (PPM vs control: η²_p=0.06, mean 117.8, SD 514 minutes; SFII vs control: η²_p=0.08, mean 145.3, SD 616 minutes). At 8 weeks, PPM maintained a small effect in MVPA relative to the control (η²_p=0.01, mean 22.8, SD 249 minutes) and SFII displayed a medium effect size (η²_p=0.07, mean 113.8, SD 256 minutes). Small effects were observed for PPM and SFII relative to the control for systolic blood pressure (SBP) and diastolic blood pressure (DBP) (PPM: η²_p=0.12, Δmean SBP 7.1, SD 23.61 mm Hg; η²_p=0.04, Δmean DBP 3.5, SD 6.2 mm Hg; SFII: η²_p=0.01, Δmean SBP -0.4, SD 1.4 mm Hg; η²_p=0.02, Δmean DBP -2.3, SD 7.7 mm Hg) and relative autonomy index (PPM: η²_p=0.01; SFII: η²_p=0.03).

CONCLUSIONS

The feasibility metrics and preliminary findings suggest that a future full-scale randomized controlled trial examining the efficacy of PPM and SFII relative to a control is feasible, and studies with longer duration are warranted.

Correlates of Physical Activity Participation among Individuals Diagnosed with Cancer: An Application of the Multi-Process Action Control Framework

BACKGROUND

The purpose of this study was to test Multi-Process Action Control (M-PAC) processes as correlates of physical activity (PA) intention formation and translation (i.e., action control) in individuals diagnosed with cancer.

METHODS

This study was a cross-sectional survey, completed from July to November of 2020 during the COVID-19 pandemic. PA and M-PAC processes were self-reported using the Godin Leisure-Time Exercise Questionnaire and questionnaires for reflective (instrumental/affective attitudes, perceived opportunity/capability), regulatory (e.g., goal-setting, planning), and reflexive processes (habit, identity). Separate hierarchical multinomial logistic regression models determined correlates of intention formation and action control.

RESULTS

Participants (n = 347; M_age= 48.2 ± 15.6) were primarily diagnosed with breast cancer (27.4%) and at a localized stage (85.0%). Most participants intended to perform PA (70.9%), yet only 50.4% met guidelines. Affective judgements (p < 0.001) and perceived capability (p < 0.01) were significantly associated with intention formation. Preliminary models indicated employment, affective judgements, perceived capability, and self-regulation to be significant (ps < 0.05) correlates of action control, but in the final model, only surgical treatment (p = 0.02) and PA identity (p < 0.001) were significantly associated with action control.

CONCLUSION

Reflective processes were associated with PA intention formation, while reflexive processes were associated with PA action control. Behavior change efforts for individuals diagnosed with cancer should extend beyond social-cognitive approaches to include regulatory and reflexive processes of PA behavior (i.e., PA identity).

A school-family blended multi-component physical activity program for Fundamental Motor Skills Promotion Program for Obese Children (FMSPPOC): protocol for a cluster randomized controlled trial

BACKGROUND

Fundamental motor skills (FMSs) are crucial for children's health and comprehensive development. Obese children often encounter a considerable challenge in the development of FMSs. School-family blended PA programs are considered a potentially effective approach to improve FMSs and health-related outcomes among obese children, however, empirical evidence is still limited. Therefore, this paper aims to describe the development, implementation, and evaluation of a 24-week school-family blended multi-component PA intervention program for promoting FMSs and health among Chinese obese children, namely the Fundamental Motor Skills Promotion Program for Obese Children (FMSPPOC) employing behavioral change techniques (BCTs) and building on the Multi-Process Action Control (M-PAC) framework as well as using the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework for improving and evaluating the program.

METHODS

Using a cluster randomized controlled trial (CRCT), 168 Chinese obese children (8-12 years) from 24 classes of six primary schools will be recruited and randomly assigned to one of two groups by a cluster randomization, including a 24-week FMSPPOC intervention group and a non-treatment waiting-list control group. The FMSPPOC program includes a 12-week initiation phase and a 12-week maintenance phase. School-based PA training sessions (2 sessions/week, 90 min each session) and family-based PA assignments (at least three times per week, 30 min each time) will be implemented in the initiation phase (semester time), while three 60-min offline workshops and three 60-min online webinars will be conducted in the maintenance phase (summer holiday). The implementation evaluation will be undertaken according to the RE-AIM framework. For intervention effectiveness evaluation, primary outcome (FMSs: gross motor skills, manual dexterity and balance) and secondary outcomes (health behaviors, physical fitness, perceived motor competence, perceived well-being, M-PAC components, anthropometric and body composition measures) will be collected at four time-points: at baseline, 12-week mid-intervention, 24-week post-intervention, and 6-month follow-up occasions.

DISCUSSION

The FMSPPOC program will provide new insights into the design, implementation, and evaluation of FMSs promotion among obese children. The research findings will also supplement empirical evidence, understanding of potential mechanisms, and practical experience for future research, health services, and policymaking.

Evaluation of the peer leadership for physical literacy intervention: A cluster randomized controlled trial

PURPOSE

The purpose of this research was to develop, implement, and test the efficacy of a theory-driven, evidence-informed peer leadership program for elementary school students (Grade 6 and 7; age 11-12 years) and the Grade 3/4 students with whom they were partnered. The primary outcome was teacher ratings of their Grade 6/7 students' transformational leadership behaviors. Secondary outcomes included: Grade 6/7 students' leadership self-efficacy, as well as Grade 3/4 motivation, perceived competence, general self-concept, fundamental movement skills, school-day physical activity, and program adherence, and program evaluation.

METHODS

We conducted a two-arm cluster randomized controlled trial. In 2019, 6 schools comprising 7 teachers, 132 leaders, and 227 grade 3 and 4 students were randomly allocated to the intervention or waitlist control conditions. Intervention teachers took part in a half-day workshop (January 2019), delivered 7 x 40 minute lessons to Grade 6/7 peer leaders (February and March 2019), and these peer leaders subsequently ran a ten-week physical literacy development program for Grade 3/4 students (2x30 minutes sessions per week). Waitlist-control students followed their usual routines. Assessments were conducted at baseline (January 2019) and immediately post-intervention (June 2019).

RESULTS

The intervention had no significant effect on teacher ratings of their students' transformational leadership (b = 0.201, p = .272) after controlling for baseline and gender. There was no significant condition effect for Grade 6/7 student rated transformation leadership (b = 0.077, p = .569) or leadership self-efficacy (b = 3.747, p = .186) while controlling for baseline and gender. There were null findings for all outcomes related to Grade 3 and 4 students.

DISCUSSION

Adaptions to the delivery mechanism were not effective in increasing leadership skills of older students or components of physical literacy in younger Grade 3/4 students. However, teacher self-reported adherence to the intervention delivery was high.

Family-based physical activity interventions and family functioning: A systematic review

Family physical activity (PA) can confer multiple health benefits, yet whether PA interventions affect general family functioning has not been appraised. The purpose of this review was to evaluate studies that have examined the effect of family PA interventions, where child PA was the focus of the intervention, on constructs of family functioning. Literature searches were concluded on January 11, 2022 using seven common databases. Eligible studies were in English, utilized a family PA intervention, and assessed a measure of family functioning as a study outcome. The initial search yielded 8413 hits, which was reduced to 20 independent PA interventions of mixed quality after screening for eligibility criteria. There was mixed evidence for whether family PA interventions affected overall family functioning; however, analyses of subdomains indicated that family cohesion is improved by PA interventions when children are in the early school years (aged 5-12). High-quality studies also showed an impact of family PA interventions on family organization. Targeted interventions at specific family subsystems (e.g., father-son, mother-daughter), characteristics (low-income, clinical populations, girls), and broad multibehavioral interventions may have the most reliable effects. Overall, the findings show that family PA interventions can promote family cohesion and organization, particularly among families with children in the early school years. Higher quality research, employing randomized trial designs and targeting specific intervention and sample characteristics (e.g., different clinical conditions, specific parent-child dyads), is recommended in order to better ascertain the effectiveness of these approaches.

Affective Response to Exercise and Affective Judgments as Predictors of Physical Activity Intention and Behavior among New Mothers in their first 6-Months Postpartum

BACKGROUND

Understanding the predictors of moderate to vigorous physical activity (MVPA) during early postpartum is important to improve promotion efforts. Affect-related constructs are key predictors of MVPA but have limited research in mothers during the postpartum period.

PURPOSE

To examine two affect-related constructs (affective response to exercise and affective judgments) as predictors of MVPA intention and behavior across three months, among a sample of new mothers.

METHODS

Participants were 105 mothers (M age = 30.64 years; SD = 3.93) who completed measures during postpartum at 2-months post-birth of their first child. The affective response to exercise (assessed at baseline [2-months postpartum] during a submaximal treadmill test), affective judgments and intention (baseline, 6-weeks after baseline), and MVPA (baseline, 6- and 12-weeks after baseline) were assessed via self-report.

RESULTS

Path analysis, using ordinary least squares regression, showed that the affective response during exercise was a significant predictor of intention (baseline, 6-weeks), as well as change in intention from baseline to 6-weeks. By contrast, affective judgments predicted intention at 6-weeks, but not at baseline or in the change model. Past MVPA did not moderate these findings, although the affective response during exercise also had a significant indirect effect on MVPA through intention at 6-weeks and 12-weeks.

CONCLUSIONS

Interventions targeting women's affective response during exercise may be important during postpartum, perhaps through self-paced physical activity guidance. Affective judgments may not be predictive of MVPA, in part due to unanticipated changes during early postpartum leading to inaccurate expectations of the physical activity experience.

Development and Validation of a Two-component Perceived Control Measure

BACKGROUND

Research indicates that perceived behavioral control (PBC) is an important determinant of behavior and that it is composed of perceived capability and opportunity. However, typical measurement of these constructs may be confounded with motivation and outcome expectations. Vignettes presented before questionnaire items may clarify construct meaning leading to precise measurement.

PURPOSE

The purpose of this study was to develop and validate measures of perceived capability and opportunity that parse these constructs from the influence of motivation and outcome expectations using vignettes.

METHODS

Study 1 collected feedback from experts (N = 9) about the initial measure. Study 2a explored internal consistency reliability and construct and discriminant validity of the revised measure using two independent samples (N = 683 and N = 727). Finally, using a prospective design, Study 2b (N = 1,410) investigated test-retest reliability, construct and discriminant validity at Time 2, and nomological validity.

RESULTS

After Study 1, the revised measure was tested in Studies 2a and 2b. Overall, the evidence suggests that the measure is optimal with four items for perceived capability and three for the perceived opportunity. The measure demonstrated strong internal consistency ( > 0.90) and test-retest reliability (intraclass correlation coefficients [ICCs] > .78). The measure also showed construct and discriminant validity by differentiating itself from behavioral intentions (i.e., motivation) and affective attitude (based on expected outcomes) (SRMR = 0.03; RMSEA = 0.06). It also demonstrated evidence of nomological validity as behavior 2 weeks later was predicted.

CONCLUSIONS

We recommend researchers use this tool in future correlational and intervention studies to parse motivation and outcome expectations from perceived capability and opportunity measurement.

Insights into effects of individual, dyadic, and collaborative planning interventions on automatic, conscious, and social process variables

OBJECTIVE

Going beyond the effects of individual planning ("I-for-me"), we investigate the associations of dyadic ("we-for-me") and collaborative ("we-for-us") planning with automatic, conscious, and social process variables that may elucidate the differences through which these three types of planning operate. We tested the effects of three planning interventions on: (1) habit strength, representing an automatic process, (2) the use of individual planning, representing a conscious process, (3) the use of collaborative planning, representing conscious and social processes, and (4) collaborative social control, representing a social process.

METHODS

N = 320 adults were randomly assigned to one of four conditions: (1) the active control condition, (2) the individual planning condition, (3) the dyadic planning condition, or (4) the collaborative planning condition. Self-reported data on habit strength, the use of individual planning, the use of collaborative planning, and collaborative social control were assessed at baseline and at the 9-week follow-up. Analyses used linear mixed modelling.

RESULTS

Compared to the control group, participants in the individual planning condition had stronger habits at the 9-week follow-up. Those in the dyadic planning condition reported higher levels of the use of collaborative planning and higher levels of collaborative social control at the follow-up. Finally, compared to those assigned to the control group, participants in the collaborative planning condition reported stronger habits, higher levels of the use of both individual and collaborative planning, and higher levels of collaborative social control at the follow-up.

CONCLUSIONS

Individual, dyadic, and collaborative planning interventions may result in distinct patterns of changes in the variables representing automatic, conscious, and social processes. In particular, changes in automatic, conscious and social process variables, evoked by the collaborative "we-for-us" planning intervention may reflect the major regulatory effort of forming joint plans and subsequently integrating regular joint exercise into the weekly schedule.

Changes in virus-transmission habits during the COVID-19 pandemic: a cross-national, repeated measures study

OBJECTIVE

The COVID-19 pandemic saw promotion of novel virus transmission-reduction behaviours, and discouragement of familiar transmission-conducive behaviours. Understanding changes in the automatic nature of such behaviours is important, because habitual behaviours may be more easily reactivated in future outbreaks and disrupting old habits may discontinue unwanted behaviours.

DESIGN

A repeated-measures, multi-national design tracked virus-transmission habits and behaviour fortnightly over six months (Apr-Sept 2020) among 517 participants (age M = 42 ± 16y, 79% female).

MAIN OUTCOME MEASURES

Within-participant habit trajectories across all timepoints, and engagement in transmission-reduction behaviours (handwashing when entering home; handwashing with soap for 20 seconds; physical distancing) and transmission-conducive behaviours (coughing/sneezing into hands; making physical contact) summed over the final two timepoints.

RESULTS

Three habit trajectory types were observed. Habits that remained strong ('stable strong habit') and habits that strengthened ('habit formation') were most common for transmission-reduction behaviours. Erosion of initially strong habits ('habit degradation') was most common for transmission-conducive behaviours. Regression analyses showed 'habit formation' and 'stable strong habit' trajectories were associated with greater behavioural engagement at later timepoints.

CONCLUSION

Participants typically maintained or formed transmission-reduction habits, which encouraged later performance, and degraded transmission-conducive habits, which decreased performance. Findings suggest COVID-19-preventive habits may be recoverable in future virus outbreaks.

A 4-Yr Mixed Longitudinal Study of Health Behaviors and Fat Mass Accrual during Adolescence and Early Adulthood

PURPOSE

Physical activity (PA), sedentary time (SED), and energy intake (EI) are associated with fat mass accrual in children and youth. Previous studies relied primarily on cross-sectional designs and proxy measures of body composition such as body mass index. We aimed to prospectively investigate associations between PA, SED, EI, and total body fat mass accrual using dual-energy x-ray absorptiometry.

METHODS

This analysis of the mixed longitudinal Healthy Bones III Study included data from 312 participants (138 boys age 9 to 21 yr at baseline). For each participant, we acquired a maximum of four annual total body dual-energy x-ray absorptiometry scans from which we determined fat mass (in kilograms; n = 748 observations). We assessed total PA, moderate-to-vigorous PA (MVPA) and SED with accelerometers (ActiGraph GT1M) and measured EI via 24-h dietary recall. We fit sex-specific multilevel models adjusting for maturity (years from age at peak height velocity (APHV)), weight status, ethnicity, total PA, MVPA, SED, and EI.

RESULTS

Boys and girls demonstrated divergent trajectories of fat mass accrual; rate of fat mass accrual in girls was four times greater than boys at APHV and increased across adolescence, whereas boys' fat mass plateaued after APHV. In boys, within-person change in MVPA negatively predicted fat mass independent of SED; each annual increase in MVPA of 6 min·d -1 was associated with a 0.21-kg lower fat mass. In girls, between-person average MVPA negatively predicted fat mass accrual independent of SED; greater MVPA of 4 min·d -1 across adolescence was associated with a 0.31-kg lower fat mass.

CONCLUSIONS

MVPA demonstrates an independent and negative effect on fat mass in boys and girls. Given different trajectories of fat mass accrual and movement behaviors between boys and girls, PA interventions aimed at preventing obesity in youth may benefit from a sex and gendered approach.

Analysis of dynamic psychological processes to understand and promote physical activity behaviour using intensive longitudinal methods: a primer

Physical activity behaviour displays temporal variability, and is influenced by a range of dynamic psychological processes (e.g., affect) and shaped by various co-occurring events (e.g., social/environmental factors, interpersonal dynamics). Yet, most physical activity research tends not to examine the dynamic psychological processes implicated in adopting and maintaining physical activity. Intensive longitudinal methods (ILM) represent one particularly salient means of studying the complex psychological dynamics that underlie and result from physical activity behaviour. With the increased recent interest in using intensive longitudinal data to understand specific dynamic psychological processes, the field of exercise and health psychology is well-positioned to draw from state-of-the-art measurement and statistical approaches that have been developed and operationalised in other fields of enquiry. The purpose of this review is to provide an overview of some of the fundamental dynamic measurement and modelling approaches applicable to the study of physical activity behaviour change, as well as the dynamic psychological processes that contribute to such change.

Examining whether affectively-charged motivations predict subsequent affective response during physical activity: An ecological momentary assessment study

BACKGROUND

Evidence suggests positive affective response during physical activity increases the likelihood of engaging in and maintaining regular activity exercise in the future. Elucidating antecedents for a positive affective response may help identify intervention strategies to increase activity. Affectively-charged motivations (e.g., desires, urges, dreading) have been posited as proximal antecedents to physical activity but have yet to be examined in terms of their influence on affective response in real-world settings. The current study used ecological momentary assessment (EMA) to examine within-subject effects of pre-physical activity affectively-charged motivation on subsequent affective response during physical activity.

METHODS

Participants included 56 adults (M = 39.18 years, SD = 11.98; 67.86% female) who completed a 14-day smartphone-based EMA study. Prior to starting physical activity (time t), participants self-initiated an event-contingent EMA survey that assessed affectively-charged motivation for physical activity (i.e., rating scale from "dreading it" to "excited to do it"). EMA surveys prompted during subsequent physical activity (time t + 15 min) assessed affective response (i.e., feeling good-bad, energized-exhausted, thrilled-miserable, interested-bored, and relaxed-nervous). Multi-level linear regression models examined within-subject effects of pre- physical activity affectively-charged motivations on subsequent affective response during physical activity controlling for between-subjects effects of affectively-charged motivation, age, biological sex, time of day, and day of the week.

RESULTS

Overall, there were N = 304 physical activity occasions in the analysis (M = 5.43, SD = 3.97). When individuals reported more positive affectively-charged motivation for physical activity than usual before physical activity occasions, they reported feeling more energized (Estimate = 0.22, p < 0.001), good (Estimate = 0.25, p < 0.001), thrilled (Estimate = 0.12, p = 0.02), and interested (Estimate = 0.24, p < 0.001) during subsequent physical activity. Affectively-charged motivation was not associated with feeling more relaxed (Estimate = 0.11, p = 0.13) during subsequent physical activity.

CONCLUSION

Momentary affectively-charged motivations predicted more positive affective response during subsequent physical activity among active adults. Future research can explore potential sources of intraindividual differences in affectively-charged motivations and further examine these associations with future physical activity behavior. To improve positive affective responses, interventions may boost affectively-charged motivations through real-time mobile prompting in naturalistic settings.

Psychological needs and exercise behaviour: a comparison of two psychological needs models

OBJECTIVE

Psychological need satisfaction, from a self-determination theory (SDT) perspective, has been applied extensively to understand predictors of exercise behaviour. Dweck proposed a psychological needs framework that includes basic needs (optimal predictability, competence, acceptance), compound needs derived from combinations of basic needs (self-esteem/status, trust, control), and a superordinate compound need for self-coherence that includes identity and meaning. The purpose was to examine whether psychological needs operationalized within Dweck's model account for variance in exercise behaviour in ways that the SDT model does not.

METHODS AND MEASURES

A community sample of 403 adults completed measures of demographics, psychological needs, and exercise motivation at Time 1, and self-reported moderate-to-vigorous minutes of exercise at both Times 1 and 2 four weeks later.

RESULTS

Two structural equation models operationalizing Dweck's needs framework and SDT (basic needs and motivation) were examined in relation to exercise behaviour. In both models, exercise identity and integrated regulation (conceptually similar) were the most salient correlates of prospectively measured exercise behaviour, and both accounted for the relationship between competence and exercise behaviour.

CONCLUSION

The results support the importance of identity in the context of exercise behaviour. Future research should investigate factors associated with adopting and maintaining an exercise identity.

Reflecting on physical activity across 2 years of the COVID-19 pandemic: Predictors of intention-behavior profiles

The COVID-19 pandemic has affected how many people engage in regular moderate-to-vigorous intensity physical activity (MVPA). The purpose of this study was to predict current and dynamic (across 2 years of the pandemic) intention and MVPA profiles using the multi-process action control (M-PAC) framework. A representative sample of 977 English-speaking Canadians (18 + years) completed measures of reflective (instrumental attitude, affective attitude, perceived capability, and opportunity), regulatory (planning and self-monitoring), and reflexive (habit and identity) processes, intention, and MVPA. These measures included current assessments and reflections prior to the COVID-19 restrictions. Three current intention-behavior profiles (nonintenders, unsuccessful intenders, and successful intenders) and five dynamic intention-MVPA by prepandemic MVPA profiles (consistent nonintenders, relapsed nonintenders, consistent unsuccessful intenders, relapsed unsuccessful intenders, and consistent successful intenders) emerged from these data, showing few increased MVPA across the pandemic. The current and dynamic profiles were subsequently predicted by changes in specific reflective, regulatory, and reflexive processes across the pandemic; however, only change in identity was the critical predictor of successful MVPA engagement in the dynamic 2-year MVPA profiles. Collectively, the findings support the joint promotion of reflective, regulatory, and reflexive processes in the choice of behavior change techniques to promote postpandemic MVPA intention and behavior.

The Development of a Hypertension Prevention and Financial Incentive Mobile Health Program Using a “No-Code” Mobile App Builder: A Development and Usability Study (Preprint)

BACKGROUND

Regular physical activity (PA) is a key lifestyle component for hypertension prevention. Previous studies have shown that mobile health (mHealth) apps can be an effective tool for improving PA behaviors. However, adherence to and poor engagement with these apps is a challenge. A potential solution to overcome this challenge may be to combine financial incentives with innovative behavior theory, such as the Multiprocess Action Control (M-PAC) framework. Currently, there is a lack of PA financial incentive-driven M-PAC mHealth programs aimed at hypertension prevention.

OBJECTIVE

We aimed to describe the process of developing an 8-week mHealth PA and financial-incentive hypertension education program (Healthy Hearts) and to evaluate usability of the Healthy Hearts program.

METHODS

The first 2 stages of the Integrate, Design, Assess, and Share framework were used to guide the development of the Healthy Hearts program. The development process consisted of 2 phases. In phase 1, the research team met to discuss implementing the M-PAC framework to adopt an existing web-based hypertension prevention program to a mobile app. The app was developed using a no-code app development platform, Pathverse (Pathverse Inc), to help decrease overall development time. In phase 2, we created a prototype and conducted usability testing to evaluate lesson 1 of the Healthy Hearts program to further enhance the user experience. We used semistructured interviews and the mHealth App Usability Questionnaire to evaluate program acceptability and usability.

RESULTS

Intervention development among the research team successfully created an 8-week financial-incentive hypertension education program for adults aged 40-65 years who did not currently meet the Canadian Physical Activity Guidelines (<150 minutes of moderate to vigorous PA per week). This program lasted 8 weeks and comprised 25 lessons guided by the M-PAC framework. The program used various behavior change techniques to further support PA adherence. Usability testing of the first lesson was successful, with 6 participants recruited for 2 rounds of testing. Feedback was gathered to enhance the content, layout, and design of the Healthy Hearts program to prepare the mHealth program for feasibility testing. Results of round 1 of usability testing suggested that the content delivered in the lessons was long. Therefore, the content was divided into multiple lessons before round 2 of usability testing, where feedback was only on design preferences. A minimum viable product was created with these results.

CONCLUSIONS

The iterative development process and the usability assessments suggested by the Integrate, Design, Assess, and Share framework enabled participants to provide valuable feedback on the content, design, and layout of the program before advancing to feasibility testing. Furthermore, the use of the "no-code" app development tool enabled our team to rapidly make changes to the app based on user feedback during the iterative design process.

The influence of sleep and movement on mental health and life satisfaction during the transition to parenthood

OBJECTIVES

This study assessed whether sleep and physical activity impact mental health and life satisfaction across the transition to parenthood. This study assessed the impact of parenthood on mental health of new parents and parents expecting their second child, and whether change in mental health occurred dyadically across couples.

DESIGN

Longitudinal 12-month study.

PARTICIPANTS

One hundred and fifty-seven couples (N = 314) between the ages of 25 and 40, who were not expecting to have a child (n = 102), expecting their first child (n = 136), or expecting their second child (n = 76) were recruited.

MEASUREMENTS

Participants completed measures at baseline, 6 months, and 12 months. Sleep was assessed with how often participants met sleep guidelines (7-9 hours). Physical activity was measured objectively via accelerometers. Mental health was measured using 6 items from the short form-12 Quality of Life Survey. Life satisfaction was assessed with the Satisfaction with Life Scale (5 items).

RESULTS

Mental health was not predicted by physical activity but was predicted by sleep. Sleep at 6 months was positively related to mental health at 6 months (β = 0.156, p < .001), and sleep at 12 months was positively related to mental health at 12 months (β = 0.170, p < .001). The change in mental health did not occur dyadically: mental health increased for women but not for men across groups. Mental health was positively related to life satisfaction at 6 months (β = 0.338, p < .001) and 12-months (β = 0.277, p < .001).

CONCLUSIONS

For new and established parents, getting sufficient sleep plays an important role in mental health and, in turn, life satisfaction.
