Associations between parent perceived social cognitive factors and child objectively measured physical activity behaviors among preschool-aged children

Grounded in social cognitive theory (SCT), this study sought to examine whether parents perceived social cognitive factors regarding children's physical activity (PA) behaviors were associated with preschool children's moderate-to-vigorous PA (MVPA) levels. A total of 142 Hong Kong parent-child pairs from five preschools/childcare centers completed all assessments in the cross-sectional study. Children’s (42% girls; mean age = 4.52 ± 0.67 years) PA was measured through accelerometers. Parents (74% mothers; mean age = 37.38 ± 4.63 years) completed a paper-based questionnaire assessing the social cognitive factors on their children’s PA participation. The data were analyzed using latent variable structural equation modeling. Findings revealed that the model showed acceptable fit with the data: χ² (23) = 38.14, p = .025, χ²/df = 1.66, CFI = 0.955, TLI = 0.929, RMSEA = 0.068, 90% CI [0.025, 0.106], and SRMR = 0.072. The model accounted for 39.1% of the variance in the PA behavior of preschool-aged children. Structural equation modelling revealed parental self-efficacy (β = 0.29, 95% CI [0.95, 0.49]) and goal setting (β = 0.25, 95% CI [0.06, 0.44]) were directly associated with children’s MVPA. Outcome expectations (β = 0.09, 95% CI [0.01, 0.03]) and goal setting (β = 0.18, 95% CI [0.05, 0.32]) mediated the association between parental self-efficacy and children’s MVPA. Indirect associations of parental self-efficacy from setting goals via parental support (β = 0.15, 95%CI [0.02, 0.30]) and perceived barriers (β = 0.15, 95% CI [0.05, 0.28]) were uncovered. Results supported the use of SCT in understanding how the parents perceived social cognitive factors predict the PA behaviors of young children. This study provides insight into whether these theoretical variables could be modified or promoted in future intervention programs. Enhancing parents’ abilities to ensure preschool-aged children are physically active is of great importance given the global decline in PA among children.     

Does parental support moderate the effect of children's motivation and self-efficacy on physical activity and sedentary behaviour?

Objectives1) To test whether parental support moderates the direct effects of children's motivation and self-efficacy on objectively measured moderate-vigorous physical activity (MVPA) and sedentary time. 2) To explore differences in the relationships between boys and girls.DesignCross-sectional observational study.MethodData were collected from 430 9–11 year old UK children and their parents; parents self-reported on the support they provided to their children to be active (through providing transport, encouragement, watching, or taking part with their child), and children self-reported their motivation and self-efficacy towards exercise. MVPA and sedentary time were measured using accelerometers.ResultsBoth parent- and child-level factors were largely positively associated with children's MVPA and negatively related to sedentary time. There was no evidence of a moderation effect of parental support on MVPA or sedentary time in boys. Parental provision of transport moderated the effect of girls' motivation on week-day MVPA; more motivated girls were less active when transport was provided. Transport and exercising with one's child moderated the effect of motivation and self-efficacy on girls' sedentary time at weekends; more motivated girls, and those with higher self-efficacy were less sedentary when parents provided more frequent transportation or took part in physical activity with them.ConclusionsThe results largely supported a model of the independent effects of parent and child determinants for moderate-to-vigorous physical activity, but there was evidence that some types of parent support can moderate sedentary time in girls. Further research is needed to explore the causal pathways between the observed cross-sectional results.     

Change in the social context of physical activity across adolescence and its association with moderate-to-vigorous intensity physical activity

We examined whether changes in social context (i.e., frequency with which youth engage in physical activity [PA] alone, with teammates, with friends, with siblings, or with parents/grandparents) is associated with change in moderate-to-vigorous intensity PA (MVPA) across Grades 5–8 and Grades 8–11 (N = 938). Data were self-reported annually. Across Grades 5–8, the frequency of PA in all social contexts declined over time, and changes in the frequency of PA alone, with teammates, with siblings, and in diversity of PA companion types were positively associated with change in MVPA. Across Grades 8–11, the frequency of PA with siblings, friends, and parents/grandparents declined over time, and changes in the frequency of PA alone, with teammates, with friends, with parents/grandparents, and in diversity of PA companion types were positively associated with change in MVPA. PA social contexts vary in how they associate with change in MVPA in youth over time.     

From enjoyment to physical activity or from physical activity to enjoyment? Longitudinal associations in parent–child dyads

Abstract

Background: This longitudinal dyadic study used cross-lagged analyses to examine reciprocal patterns of associations between physical activity (PA) enjoyment and moderate-to-vigorous PA (MVPA) among children and their parents.

Methods: At Time 1 (T1) 879 parent–child dyads provided their data. The follow-up (Time 2, T2) took place 7–8-months later. MVPA and PA enjoyment scales were filled out separately by parents and children at T1 and T2.

Findings: Child PA enjoyment (T1) predicted a higher level of child MVPA (T2), parental PA enjoyment (T1) explained a higher level of parental MVPA (T2), and parental MVPA (T1) predicted a higher level of parental PA enjoyment (T2). Furthermore, child PA enjoyment (T1) predicted a higher level of parental PA enjoyment (T2).

Conclusions: Child PA enjoyment was the key variable predicting child and parental outcomes. In particular, it explained child MVPA, but also PA enjoyment among parents.     

Changes in physical activity and sedentary behavior associated with an exercise intervention in depressed adults

BackgroundExercise is beneficial for depression, but less is known about its impact on post-intervention physical activity and sedentary behavior. The aim of this paper was to determine the extent to which participation in light-, moderate- and vigorous-intensity exercise intervention influenced habitual physical activity and sedentary behavior patterns in depressed adults.MethodsAccelerometer data was collected pre- and post-intervention from depressed participants randomized to one of three 12-week intervention groups: light (n = 21), moderate (n = 25) and vigorous (n = 22) exercise. Mixed models examined changes in time spent sedentary and in light and moderate-to-vigorous physical activity (MVPA); time accumulated in sedentary and MVPA bouts; and, number of MVPA bouts and interruptions in sedentary time.ResultsOverall sedentary time decreased while light activity time increased across all intervention groups but not significantly so. The light exercise intervention group reduced MVPA minutes (−8.22, 95% CI: −16.44, −0.01), time in MVPA bouts (−8.44, 95% CI: −14.27, −2.62), and number of activity bouts (−0.43, 95% CI: −0.77, −0.09). The moderate exercise intervention group reduced time in MVPA bouts (−6.27, 95% CI: −11.71, −0.82) and number of sedentary interruptions (−6.07, 95% CI: −9.30, −2.84). No changes were observed for the vigorous exercise intervention group.ConclusionsThe exercise intervention led to an increase in overall light physical activity and decrease in sedentary time, though neither change was statistically significant. Participation in the light and moderate exercise intervention groups was associated with reductions of time in MVPA bouts, but this was not evident for the vigorous exercise intervention group.     

Momentary affective response to bouts of moderate-to-vigorous physical activity predicts changes in physical activity and sedentary behavior during behavioral weight loss

BackgroundAffective responses are posited to be key predictors of the uptake and maintenance of health behaviors. However, few studies have examined how individuals’ affective response to physical activity, as well as the degree to which their affect response changes, may predict changes in physical activity and sedentary time during behavioral weight loss treatment.PurposeThe current study examined how baseline momentary affective response (i.e., stress and anxiety) to moderate-to-vigorous physical activity (MVPA) and the degree of pre--post intervention change in this response predicted change in daily sedentary, light, and MVPA time during a three-month internet-based weight loss program.MethodsWomen with overweight/obesity (final N = 37) completed 14-day ecological momentary assessment (EMA) protocols with objective measurement of physical activity (i.e., bout-related MVPA time) before and after the intervention.ResultsWomen who had more reinforcing responses to MVPA (i.e., greater reductions in anxiety and stress response following MVPA bouts) at baseline had greater increases in overall MVPA at the end of the intervention. Those who had greater anxiety reductions after MVPA bouts at baseline also evidenced less sedentary time at the end of the intervention. Changes in affective responses across the intervention were not related to changes in physical activity levels.ConclusionsFindings suggest initial levels of affective reinforcement from MVPA bouts predict future change in MVPA and sedentary time during behavioral weight loss. Future work is needed to examine the utility of more precisely targeting affective responses to physical activity to optimize intervention approaches.     

Association of physical activity and fitness with executive function among preschoolers

It is well-documented in the literature that high levels of regular physical activity (PA), low levels of sedentary behavior (SB), and high levels of cardiorespiratory fitness (CRF) are associated with superior cognitive functioning, especially with regard to older populations. However, concerning other age groups (e.g., preschoolers) the available evidence documenting such a positive relationship is relatively scarce. Thus, this study aimed to investigate the association of time spent in different PA intensity zones and CRF with executive functions (EFs) in preschool-age children. To this end, preschoolers (n = 127) aged 3 to 6 years were recruited from 9 kindergarten classes in 2 districts of Shenzhen, China. The amount and the intensity of PA were assessed via accelerometry, and the CRF level was quantified by the 20-meter shuttle run test. EFs including inhibitory control and working memory were assessed using the one-on-one iPad-based Early Year Toolbox. Results suggested that children who had a higher CRF level (“impulse control” scores: β = 0.34, p < .001; “Go” accuracy: β = 0.31, p < .001; “No-Go” accuracy: β =0.28, < .001) and spentmore time in moderate-to-vigorous physical activity (MVPA) (“impulse control” scores: β = 0.50, p < .001; No-Go” accuracy: β = 0.52, p < .001) had higher scores on inhibitory control tasks, and those who had a higher CRF level had higher scores on a working memory task (β = 0.24, p < .05). The findings are discussed in light of the positive roles of MVPA and CRF for promoting EFs, but also consider the disproportionate association of PA and CRF with working memory relative to inhibition.     

Attraction toward physical activity as a moderator of socio-cognitive predictors of physical activity

Previous research highlighted gaps between socio-cognitive factors (e.g., intentions, social norms) and physical activity (PA) participation. Recently, researchers have asserted that considering affective processes may help bridge this gap. Leveraging the affective-reflective theory of physical inactivity and exercise, this study examined whether individuals’ attraction toward PA moderated the relationship between PA intentions and behaviors, and the relationship between social norms and PA intentions. Analysis of online survey data (N_T1 = 582; N_T2 = 327) provided evidence that social norms more strongly predicted PA intentions under conditions of lower attraction to PA. However, the results differed depending on how intentions were measured: Moderation was found for intention strength as the outcome, but no moderation was found for decisional intention as the outcome. The intentions-behavior relationship, despite nonsignificant interaction terms, showed patterns of positive moderation based on changes in simple slopes: Intentions more strongly predicted PA behavior at time 2 under conditions of higher attraction to PA. The findings align with recent theorizing that emphasizes the role of affect-related determinants when understanding and promoting PA. Practically, these results suggest that intervention strategies should differ according to the individuals’ current levels of attraction toward PA.     

The impact of physical activity and sex differences on intraindividual variability in inhibitory performance in older adults

It is well-known that processing speed and executive functions decline with advancing age. However, physical activity (PA) has a positive impact on cognitive performances in aging, specifically for inhibition. Less is known concerning intraindividual variability (iiV) in reaction times. This study aims to investigate the influence of PA and sex differences on iiV in inhibitory performance during aging. Healthy adults were divided into active and sedentary groups according to PA level. To analyse iiV in reaction times, individual mean, standard deviation and the ex-Gaussian parameters were considered. An interaction between activity level and sex was revealed, sedentary females being slower and more variable than sedentary men. No sex differences were found in the active groups. These results indicate that the negative impact of sedentariness on cognitive performance in older age is stronger for females. The present findings underline the need to consider sex differences in active aging approaches.     

Compositional insights on the association between physical activity and sedentary behavior on momentary mood in daily life

ObjectiveGiven the increasing number of mental disorders, a growing body of studies now focuses on the relationship between physical activity (PA), sedentary behavior (SB), and mental health. However, momentary mechanisms and interrelatedness between PA, SB, and mood in daily life are highly understudied.MethodsTo investigate whether the composition of light physical activity (LPA), moderate-to-vigorous physical activity (MVPA), and SB influences mood, we conducted an Ambulatory Assessment study in the everyday life of 103 university students over five days. We measured PA and SB via accelerometers and assessed mood up to six times each day on smartphone diaries. We combined compositional data analyses (CoDA) with multilevel modeling to analyze within-person effects of the behavioral composition on mood.ResultsHigher ratio of the SB to LPA and MVPA composition within the 60 min prior to a diary rating negatively influenced valence (p = 0.006) and energetic arousal (p < 0.001). Furthermore, a higher ratio of LPA to SB and MVPA positively influenced energetic arousal (p < 0.001) and a higher ratio of MVPA to SB and LPA positively influenced valence (p = 0.004) and energetic arousal (p = 0.022). Simulation analyses revealed that replacing 20 min of SB with PA can influence mood rating up to 3.39 units [range from 0–100].ConclusionsFindings suggest that minutely replacements of SB with PA may lead to mood enhancements. Given the high prevalence of mental disorders, more studies are warranted to deepen the understanding of momentary compositional mechanisms between SB, PA, and mood. Applying CoDA to intensive longitudinal data can serve as a starting point to identify the optimal composition of SB, LPA, and MVPA for mood enhancements in everyday life.     

Fundamental motor skill,physical activity,and sedentary behavior in socioeconomically disadvantaged kindergarteners

Guided by Stodden et al’s conceptual model, the main purpose of the study was to examine the relation between fundamental motor skills (FMS; locomotor and objective control skills), different intensity levels of physical activity (light PA [LPA], moderate-to-vigorous PA [MVPA], and vigorous PA[VPA]), and sedentary behavior (SB) in socioeconomically disadvantaged kindergarteners. A prospective design was used in this study and the data were collected across the 2013–2014 academic school year. Participants were 256 (129 boys; 127 girls; M_age = 5.37, SD = 0.48) kindergarteners recruited from three public schools in the southern United States. Results found that FMS were significantly related to LPA, MVPA, VPA, and SB. Regression analyses indicate that locomotor skills explained significant variance for LPA (6.4%; p < .01), MVPA (7.9%; p < .001), and VPA (5.3%; p < .01) after controlling for weight status. Mediational analysis supports the significant indirect effect of MVPA on the relation between FMS and SB (95% CI: [?0.019, ?0.006]). Adequate FMS development during early childhood may result in participating in more varied physical activities, thus leading to lower risk of obesity-related behaviors.     

Momentary associations between stress and physical activity among children using ecological momentary assessment

Chronic and acute stress may have a detrimental effect on children's physical activity. Research on stress as a predictor of children's physical activity has mostly focused on stress between children, rather than how children's within-day variation in stress may predict physical activity. The current study assessed the within- and between-effects of stress on subsequent physical activity in three different time windows using ecological momentary assessment (EMA) and accelerometry. Children (N = 190; M_{Baseline Age} = 10.1 ± 0.9, 53% female, 56% self-identified Hispanic/Latino) completed six semi-annual assessment bursts across three years. During each burst, participants responded to up to seven (weekend) or three (weekday) randomly prompted EMA surveys on smartphones for seven days and wore a waist-worn accelerometer. Multi-level structural equation modeling examined within- and between-subjects effects of stress as a predictor of children's subsequent moderate-to-vigorous physical activity (MVPA) in the 15, 30, and 60 min following the EMA prompt. Latent variables were created for within- and between-subjects stress were comprised of three EMA stress items. Higher than average levels of stress (within-subjects) significantly predicted lower MVPA in the subsequent 15, 30 and 60 min (ps < .05). Between-subjects stress was not significantly associated with subsequent MVPA (ps > .05). Results indicate that elevated momentary stress predicts less subsequent MVPA. These findings suggest that within-day fluctuations in stress may be a barrier for children engaging in physical activity. Childhood physical activity promotion and interventions should consider the role of children's stress, aim to reduce the stress children experience throughout the day, and incorporate stress coping strategies.     

Longitudinal examination of objectively-measured physical activity and sedentary time among children with and without significant movement impairments

BackgroundChildren with Developmental Coordination Disorder (DCD) tend to be less active than typically-developing (TD) children. Current evidence, however, is based on cross-sectional and self-reported activity, and little is known about sedentary time among children with significant movement impairments such as DCD. The current study examines the longitudinal patterns of objectively measured physical activity and sedentary time in children with and without possible DCD (pDCD).MethodsData is from a longitudinal nested case-control study, with 103 participants (n = 60 males ages = 12 and 13 at baseline). Participants averaging ⩽16th percentile on the Movement Assessment Battery for Children were considered having significant movement impairments and pDCD (n = 49). All participants wore accelerometers for seven days.ResultsThere were significant main effects for time (Estimate = −23.98, p < .01) and gender (Estimate = 59.86, p < .05) on total physical activity, and time spent being sedentary (Estimate = 15.58, p < .05). Significant main effects for pDCD (Estimate = −5.38, p < .05) and gender (Estimate = 26.89, p < .01), and time by gender interaction (Estimate = −7.50, p < .05) were found for moderate-to-vigorous physical activity (MVPA). Sedentary time did not differ between children with and without DCD.ConclusionsResults suggest children with pDCD engaged in less MVPA compared to TD children. Consistent patterns of MVPA over time, however, suggest that the divergence in MVPA occurs earlier in childhood. Further longitudinal research following a younger cohort is necessary to identify the specific point that differences in MVPA emerge.     

Psychological,social and physical environmental mediators of the SCORES intervention on physical activity among children living in low-income communities

ObjectivesThis study examined mediation effects of socio-ecological variables on accelerometer-determined physical activity among children in the Supporting Children's Outcomes using Rewards, Exercise and Skills (SCORES) intervention.DesignRandomized control trial mediation analysis.MethodsPrimary school children were randomly assigned the SCORES multi-component intervention or control group for the 12-month study. The outcome was accelerometer derived total moderate-to-vigorous physical activity (MVPA). Hypothesized mediators measured in children were physical activity enjoyment and perceived sport competence and social support. Hypothesized mediators measured in parents were family social support, access to physical activity facilities and equipment at home, and perceived access to physical activity opportunities in the local community. Mediation analyses were conducted using multi-level linear analysis in MPlus.ResultsThere were significant intervention effects for social support from teachers (A = 1.73, SE = 0.88, p = 0.048) and parental perceived access to physical opportunities in the local community (A = 2.69, SE = 1.12, p = 0.016). There were significant associations between changes in perceived sport competence (B = 0.48, SE = 0.36, p = 0.027), parental perceived access to physical activity opportunities in the local community (B = 0.60, SE = 0.26, p = 0.021), and changes in total MVPA. Parental perceived access to physical activity opportunities in the local community was found to have a significant mediating effect on total MVPA (AB = 1.61, 95% CI = 0.06 to 3.95, proportion 13%).ConclusionsParental perceived access to physical activity opportunities in the local community is a potential mechanism of behavior change for children and mediated the effect of the SCORES intervention on objectively measured physical activity.     

Understanding physical activity declines during COVID-19: The affective repercussions of disruption to exercise routines

Recent research has examined psychological factors that forestalled declines in physical activity (PA) during the early stages of the COVID-19 pandemic. Surprisingly, there has been limited evidence of an association between intrinsic motivation (IM) and PA. We reasoned that IM may have not predicted PA because COVID-19 restrictions limited opportunities to engage in exercise in ways that produced positive affective experiences (i.e., inherent rewards). Using data from a cross-sectional survey (N = 373 participants), we tested a moderated mediation model that predicted perceived changes to affective experiences during exercise would mediate the association between disruption to one’s exercise routine and self-reported declines in PA, and that effects would be moderated by IM. Evidence of moderated mediation was found, suggesting that disruptions to exercise routines were associated with fewer positive affective experiences during exercise that predicted declines in PA engagement, especially for people who typically exercised for intrinsic reasons.     

The role of motivation in the conceptual model of motor development in childhood

The aim of this study was twofold: first, to investigate whether perceived motor competence (PMC) mediates the relation between actual motor competence (AMC) and physical activity (PA) according to the conceptual model of motor development, and second to examine the role of different motivational regulations (i.e., intrinsic, identified, introjected, and external regulation) in the relationship between PMC and PA. A sample of 504 Spanish students (46.2% girls, 8–12 years old) voluntarily participated in this study. In relation to the first aim, structural equation modeling revealed that PMC indeed mediates the association between AMC and PA. In relation to the second aim, positive associations between AMC and PMC (β = 0.32, p < .001), which in turn was positively related to intrinsic and identified regulations (β = 0.46 and β = 0.43 respectively, p < .001), were found. The model showed direct paths from intrinsic and introjected regulation to PA (β = 0.27 and β = 0.22, p < .05) and indirect paths from PMC through intrinsic motivation to PA (β = 0.13, p < .05). This study confirms that intrinsic motivation mediates the association between PMC and PA. Strategies targeting to build and develop children’s AMC and PMC, and fostering children’s intrinsic motivation should be targeted to promote children’s PA engagement and motor development.     

Parent’s physical literacy enhances children’s values towards physical activity: A serial mediation model

PurposePhysical literacy is a multidimensional concept that concerns the affective, physical, cognitive, and behavioural aspects of physical activity (PA). It plays a vital role in enhancing PA engagement. However, current research on physical literacy’s function in the family setting is scarce. Its potential effect in elevating values towards PA among parents and children is also understudied. In this study, we examined the predicting role of parents’ physical literacy on children’s values towards PA. We also explored the potential mediating roles of parents’ values towards PA and children’s perceived parental autonomy support for PA through a serial mediation model.MethodsA cross-sectional study was conducted between September 2020 and January 2021, a total of 946 primary school-age children (6–13 years) and their parents from 30 Hong Kong primary schools were recruited by cluster sampling method. Structural equation modelling analysis was conducted using Mplus 7.3.ResultsParents’ values towards PA and children’s perceived parental autonomy support for PA serially mediated between parents’ physical literacy and children’s values towards PA. Specifically, the indirect effects from parents’ physical literacy to children’s values towards PA via parents’ values towards PA (β = 0.12, 95% CI [0.06, 0.17]), and via parents’ values towards PA to children’s perceived parental autonomy support for PA (β = 0.05, 95% CI [0.02, 0.08]) were significant.ConclusionsParents’ physical literacy is a predictor of children’s values towards PA. Parental autonomy support may facilitate the intergenerational transmission of values towards PA between parents and children. Concurrent interventions that target enhancing parents’ physical literacy and parental autonomy support for PA in the family context may be more effective in raising children’s PA values.     

A longitudinal study on depressive symptoms and physical activity during the Spanish lockdown

Background/Objective: The aim was to evaluate the evolution of depressive symptoms and to explore the influence of physical activity (PA) practice during the home confinement due to the COVID-19 outbreak in Spain. Method: Information was collected from 595 confined participants who reported personal and contextual information, depressive symptoms and PA levels at four time points. Results: The changes in depressive symptoms were analyzed using a linear mixed model with cubic splines. Results showed a significant increase, with a significant rise between T1 and T2 (OR = 2.38, 95% CI = 1.83-3.10). It continued growing until T4 (OR = 2.93, 95% CI = 1.97-4.38). A negative relationship was observed between the increase in depressive symptoms and moderate-to-vigorous physical activity (MVPA) levels, with a significant slope up to 4 hours of MVPA per week (OR = 0.51, 95% CI = 0.29-0.90) that tended to increase until 16 hours per week of MVPA (OR = 0.41, 95% CI = 0.20-0.87). Conclusions: Results from a partition model showed that moderate intensity of PA could be enough to prevent an increase of depressive symptoms during home isolation.     

Family Cohesion and Health-Related Quality of Life of Children with Type 1 Diabetes: The Mediating Role of Parental Adjustment

Despite the increasing number of studies on the health-related quality of life (HRQOL) of children with type 1 diabetes (T1D), little is known about the influence of family and parental factors on this outcome. This study aimed to explore whether family cohesion and children’s HRQOL were connected through three indicators of parental psychological adjustment (parenting stress, depressive symptoms, and anxious symptoms) as well as whether these links varied according to the child’s age. Levels of family cohesion, parenting stress, and depression/anxiety symptoms of parents of children with T1D and parents of healthy children were compared. The sample included 88 child–parent dyads composed of children/adolescents (8–18 years old) with T1D and one of their parents and 121 dyads composed of healthy children/adolescents and one of their parents. The parents completed self-report measures of family cohesion, parenting stress, and emotional adjustment, and the children completed measures of HRQOL. Testing of the hypothesized moderated mediational model showed that higher HRQOL ratings in children were associated with higher levels of cohesion through lower levels of parental stress, regardless of the child’s age. Parents of children with T1D perceived less cohesion and felt more anxiety and stress about parenting tasks compared to parents of healthy children. Our findings suggest that parents of children with T1D are at an increased risk of psychological maladjustment. Moreover, this study highlights the interrelation between family/parental functioning and child adjustment and makes an innovative contribution by identifying a mechanism that may account for the link between family and child variables.     

Motivation beliefs,emotions, leisure time physical activity,and sedentary behavior in university students: A full longitudinal model of mediation

Discrete emotions produce predictable response tendencies, yet there is limited understanding about their potential to mediate relations between motivation beliefs and leisure time physical activity (LTPA) and sedentary behavior. The current study investigates self-reported moderate LTPA, vigorous LTPA, and sedentary behavior as measured by the Global Physical Activity Questionnaire using control – value theory of achievement emotions (CVTAE) with a full longitudinal mediation design. A total of 586 young adults (Mage = 19.44, SD = 1.43) completed 1485 time-specific reports of LTPA, sedentary behavior, PA enjoyment, LTPA boredom, and control and value beliefs toward PA across three waves of data collection. Structural equation modeling was used to systematically disentangle direct and indirect relations over time. Neither enjoyment nor boredom mediated relations between participants’ control and value beliefs and moderate LTPA, vigorous LTPA, or sedentary behavior; however, boredom did negatively predict vigorous LTPA. There were reciprocal relations between control beliefs and moderate LTPA as well as value beliefs and PA enjoyment. The final model did not support relationships posited by CVTAE for LTPA or sedentary behavior. However, theoretically grounded CVTAE constructs explained substantive amounts of variance in moderate and vigorous LTPA but not sedentary behavior.
