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.

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.

Promoting physical activity (PA) and fundamental movement skills (FMS) in early childhood is necessary to address physical inactivity in young children. Parent support is a known predictor of PA in children, however, parents who intend to support PA do not always follow through with these intentions. This is referred to as the intention­behavior gap. Applying the theoretical tenets of the multi-process action control framework, this study surveyed 124 parents of children aged 3­4 years on reflective (e.g., attitudes), regulatory (e.g., planning), and reflexive (e.g., habit) processes, intentions, and behaviors related to parent PA and FMS support. Follow-up interviews were completed with 20 parents to gain a deeper understanding of parent PA and FMS support behaviors. Survey findings showed that parents' intentions and support behaviors for their child's PA and FMS were associated with a combination of reflective, regulatory, and reflexive processes. Interview findings highlighted more favorable parent perspectives toward PA support compared with FMS and further explained the psychological processes associated with each. Future parent PA support interventions during early childhood should include FMS support strategies and foster a combination of reflective, regulatory, and reflexive behaviors to bridge the gap between intentions and support behaviors among parents of young children.

Impact of symptoms, experiences, and perceptions of the menstrual cycle on recreational physical activity of cyclically menstruating individuals: A systematic review.

OBJECTIVE: The menstrual cycle often presents barriers to participation in daily life activities, including physical activity (PA), which is a cornerstone of health and well-being. The purpose of this systematic review was to explore and summarize the impact of symptoms, experiences, and perceptions of the menstrual cycle on recreational PA (RPA), including sports, exercise and active recreation, in the general population. METHODS: Six databases were searched for studies that investigated the impact of the menstrual cycle on PA among individuals who were cyclically menstruating, healthy, and not involved in professional sports training. RESULTS: The search yielded 3025 studies that were screened for relevance and eligibility, resulting in 25 eligible studies, which were found to be of moderate-to-high quality following a quality and risk-of-bias assessment. Thematic synthesis of qualitative and quantitative data from the selected studies, constituting 16,557 adults and 3715 adolescents, identified the impact of menstrual symptoms on the physical and psychological capability to participate in RPA, social opportunity barriers to RPA (e.g., social pressure due to the sociocultural taboo against menstruation), as well reflective (knowledge) and automatic (habit) motivation on RPA behaviours. CONCLUSION: The variability in menstrual symptoms and corresponding experiences suggested the need for an individualized approach to RPA promotion. Furthermore, this review highlighted the need to address the sociocultural taboo against menstruation, as well as improve the provision of knowledge and resources related to the menstrual cycle and RPA, in order to promote and facilitate RPA for cyclically menstruating individuals throughout the menstrual cycle.

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.

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.

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 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.

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.

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.

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. The purpose of this study was 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. Participants were 105 mothers who completed measures of affective response to exercise (assessed at 2 months postpartum during a sub-maximal treadmill test), affective judgments and intention (2 months postpartum, and 6-weeks after), and MVPA (2 months postpartum, 6- and 12-weeks after). The affective response during exercise was a significant predictor of intention as well as change in intention over time. By contrast, affective judgments was a less reliable predictor across the study. 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.

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.

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.

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).

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.

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.

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.

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.

Identifying Risk Profiles for Nonadherence to the 24-Hour Movement Guidelines for Children and Youth 6 Months Into the COVID-19 Pandemic.

PURPOSE: The purposes of the current study were to identify risk profiles for nonadherence among children and youth (5-17 y) at the 6-month mark of the COVID-19 pandemic and to discuss similarities and differences between risk profiles identified in the current study and those identified at the 1-month mark of the pandemic. METHODS: Data were part of a nationally representative sample of 1143 parents (Mage = 43.07 y, SD = 8.16) of children and youth (5-17 y) living in Canada. Survey data were collected in October 2020. RESULTS: Results showed that 3.8% met all movement behavior recommendations, 16.2% met the physical activity recommendation, 27% met the screen time recommendation, and 63.8% met the sleep recommendation. Characteristics associated with nonadherence to all movement behaviors included low parental perceived capability to restrict screen time and decreased overall time spent outdoors. Characteristics associated with nonadherence to the physical activity and screen time recommendations included youth (12-17 y), low parental perceived capability to restrict screen time, decreased time spent outdoors, and increased screen time. CONCLUSION: Results emphasized the importance of parental perceived capability to restrict screen time and children's and youth's outdoor time and showed that pandemic-related factors have impacted children and youth differently.

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.

What Predicts the Physical Activity Intention-Behavior Gap? A Systematic Review.

BACKGROUND: Intention is theorized as the proximal determinant of behavior in many leading theories and yet intention-behavior discordance is prevalent. PURPOSE: To theme and appraise the variables that have been evaluated as potential moderators of the intention-physical activity (I-PA) relationship using the capability-opportunity-motivation- behavior model as an organizational frame. METHODS: Literature searches were concluded in August 2020 using seven common databases. Eligible studies were selected from English language peer-reviewed journals and had to report an empirical test of moderation of I-PA with a third variable. Findings were grouped by the moderator variable for the main analysis, and population sample, study design, type of PA, and study quality were explored in subanalyses. RESULTS: The search yielded 1,197 hits, which was reduced to 129 independent studies (138 independent samples) of primarily moderate quality after screening for eligibility criteria. Moderators of the I-PA relationship were present among select variables within sociodemographic (employment status) and personality (conscientiousness) categories. Physical capability, and social and environmental opportunity did not show evidence of interacting with I-PA relations, while psychological capability had inconclusive findings. By contrast, key factors underlying reflective (intention stability, intention commitment, low goal conflict, affective attitude, anticipated regret, perceived behavioral control/self-efficacy) and automatic (identity) motivation were moderators of I-PA relations. Findings were generally invariant to study characteristics. CONCLUSIONS: Traditional intention theories may need to better account for key I-PA moderators. Action control theories that include these moderators may identify individuals at risk for not realizing their PA intentions. Prospero # CRD42020142629.

A Systematic Review and Meta-analysis of the Outcome Expectancy Construct in Physical Activity Research.

BACKGROUND: Cognition-based theories dominate physical activity (PA) research, and many include a construct broadly defined as "beliefs about the consequences of behavior" (e.g., outcome expectancies, perceived benefits) hereafter referred to as perceived consequences. PURPOSE: With the quantity of available research on this topic, it is important to examine whether the literature supports perceived consequences as a predictor of PA. METHODS: A meta-analysis examining longitudinal associations between perceived consequences and PA in adults was conducted. Studies were eligible if (a) perceived consequences were measured at a time point prior to PA, and (b) the target behavior was a form of PA. An omnibus meta-analysis estimating the mean effect of all included studies, and separate meta-analyses for perceived consequences content categories were conducted. RESULTS: This search yielded 6,979 articles, of these, 110 studies met inclusion criteria. Studies were published between 1989 and 2020, with sample sizes ranging from 16 to 2,824. All studies were evaluated as moderate to high quality. A small positive bivariate association was identified (r = 0.11; 95% CI [0.09, 0.13]) between perceived consequences and PA. Significant associations were identified for time, health, self-evaluative, psychological, and affective consequences. There was no association between perceived weight-related consequences and PA. CONCLUSIONS: The findings emphasize the variability with which existing studies have examined perceived consequences in the PA literature. Future research might examine whether these are important distinctions for understanding PA. Overall, the results suggest utility in examining perceived consequences as a predictor of PA, but constructs with more robust associations may require priority.
