The role of action and coping planning in the relationship between intention and physical activity: A moderated mediation analysis

Objective: Using a moderated mediation model, the present study investigated whether the mediation of intention into physical activity (PA) behaviour via action planning depends on the level of coping planning.

Method: A four-month prospective study was conducted among 157 French adults, who were recruited through a web-based survey. They were administrated measures of behavioural intention and sociodemographic variables at baseline and action and coping planning and PA four months later.

Results: Action planning partially mediated the contribution of intention on PA level. However, this indirect effect was conditional on the level of coping planning, insofar as action planning acted as a mediator of the intention–PA relationship only for individuals with high level of coping planning.

Conclusion: The results highlight the complexity of the relationship between intention and behaviour and provide evidence for the distinct role of both forms of planning.     

A pilot study exploring the use of a telephone-assisted planning intervention to promote parental support for physical activity among children and youth with disabilities

Parent support is an important contributor to physical activity (PA) among children and youth with disabilities (CYD). Although many parents of CYD are motivated to provide parent PA support, CYD remain insufficiently active. The multi-process action control model has been applied to understand parent PA support and highlights behavioral regulation strategies such as action and coping planning as critical for translating intentions into behavior. Parents may struggle to create and carryout planning without support. There is no known research examining telephone support as a tool to promote planning and subsequent parent PA support behavior.MethodParents (43 mothers and 6 fathers) of CYD (child M_age = 12.53 years ± 5.53; 75% male; 38.6% developmental disability) completed a baseline questionnaire and were subsequently randomized to a telephone-assisted planning experimental group twice over four weeks (n = 23) or a control group who had access to planning tools but no telephone assistance (n = 26).ResultsNo significant main or interaction effects emerged for parent PA support behavior. However, a significant time × condition interaction was found for behavioral regulation strategies (i.e., action and coping planning and self-monitoring; F(1,44) = 5.05, p = 0.03) indicating a significant increase in the use of behavioral regulation strategies for parent PA support from baseline, for parents assigned to the telephone-assisted intervention.ConclusionThese findings suggest potential for planning support as a tool to enhance behavioral regulation strategies related to parent PA support among parents of CYD.     

Long-term effects of a dyadic planning intervention with couples motivated to increase physical activity

ObjectiveIn dyadic planning a target person and a planning partner create plans for when, where, and how the target person will change a health-relevant behavior. Across 52 weeks, direct and indirect effects of a dyadic-planning intervention on moderate-to-vigorous physical activity (MVPA) and physical fitness in target persons and their partners were investigated in a randomized controlled trial. Relationship quality was explored as a moderator.MethodsN = 338 couples (target persons randomized) were randomly assigned to a dyadic-planning- (DPC), an individual-planning- (IPC), or a no-planning dyadic-control condition (CC). MVPA was objectively assessed four times across 52 weeks using accelerometry. Physical fitness and proposed mediators (individual action control, received behavior-specific support and control) were repeatedly assessed. Relationship quality was measured at baseline. Latent growth curve-, multi-level-, and manifest mediation models were fit.ResultsAcross 52 weeks, MVPA of IPC and CC target persons increased. MVPA of DPC target persons remained stable, but those who reported high relationship quality increased their MVPA over time. DPC partners showed steeper increases in physical fitness when compared to IPC partners, but not CC partners. DPC partners’ increases in physical fitness were mediated by received support from target persons.ConclusionsThe dyadic planning intervention showed non-beneficial effects for target persons’ MVPA, but beneficial effects on their partners’ fitness. These findings resemble evidence from the social support literature indicating more benefits for support providers than for recipients.Trial registrationClinicalTrials.gov identifier: NCT01963494.     

Movement competence: Association with physical self-efficacy and physical activity

BackgroundThe purpose of this paper was to investigate whether physical self-efficacy mediates the relationship between movement competence (fundamental movement skills and perceived movement skill competence) and physical activity in children.MethodsA purposive sample of 860 children (47.7% female, 10.9 ± 1.16 years) were recruited and completed assessments for physical self-efficacy (Physical Activity Self-Efficacy Scale), fundamental movement skills (Test of Gross Motor Development-3), perceived movement skill competence (Pictorial Scale of Perceived Movement Skill Competence), and physical activity (PACE+). A bootstrap mediation analysis was employed using movement competence as the predictor variable and physical activity as the outcome variable, and physical self-efficacy as the potential mediator of the relationship.ResultsThe results from a bootstrap mediation analysis yielded a statistically significant mediation effect for physical self-efficacy, with the entire model explaining approximately 10.3% of the variance of physical activity. The indirect effect of perceived movement skill competence through physical self-efficacy was significantly larger than the indirect effect of fundamental movement skills through physical self-efficacy. Neither sex nor age acted as a covariate.ConclusionMovement competence (fundamental movement skills and perceived movement skill competence) acts as a source of information for children's physical self-efficacy, moreover physical self-efficacy mediates the movement competence – PA relationship. Findings highlight the need for interventions to target and improve movement competence as a whole for children.     

Effect of baseline self-efficacy on physical activity and psychological stress after a one-week pedometer intervention

Physical activity and psychological stress were hypothesized to improve more in participants with high self-efficacy than in those with low and medium self-efficacy after a one-week intervention. 39 female university students participated. The intervention had two steps: a lecture on self-monitoring and goal setting (160 min.) and a one-week pedometer intervention. Analyses were conducted on tertile groups according to self-efficacy at baseline. Pedometer step counts were higher in the high self-efficacy group than in the low self-efficacy group after intervention. Helplessness decreased time dependently after intervention only in the high-self-efficacy group. Because physical activity improved more in the high self-efficacy group after a one-week intervention, one hypothesis was supported.     

A brief intervention to increase physical activity behavior among adolescents using mental simulations and action planning

This study evaluated the effectiveness of a brief integrated theory-based intervention to increase physical activity (PA) among adolescents over a three-month follow-up period. A 2 (mental simulation: present vs. absent) × 2 (action planning: present vs. absent) × 4 (time: baseline vs. one-month vs. two-month vs. three-month follow-up) mixed-model randomized controlled design was adopted. Adolescents aged 14–15 years (N = 267) completed baseline psychological measures and self-reported PA followed by the relevant intervention manipulation, if appropriate, with follow-up measures collected one, two, and three months later. Results revealed no significant effects for the mental simulation and action planning strategies nor the interaction of the two strategies. However, among participants with low levels of baseline PA, participants in both mental simulation alone and action planning alone groups reported significantly higher levels of PA at one-month follow up than other groups, suggesting that individual intervention components may be effective in low-active adolescents.     

Evaluation of a school-based intervention programme to promote physical activity: an application of the theory of planned behavior

The Theory of Planned Behavior provides a useful framework to study attitudes toward participation in physical activity. The objective of the study was to test the effectiveness of an intervention in manipulating the variables of the Theory of Planned Behavior and exercise habits with 366 high school students (M = 14.2 yr., SD = .7; 201 boys and 165 girls). The students were divided into intervention and control groups. A questionnaire to measure components of the theory, and the Baecke Questionnaire of Habitual Activity measuring exercise habits, were administered. The intervention lasted 12 wk. and included posters and lectures promoting participation in physical activity. Analyses showed the intervention was effective in improving attitudes towards physical activity, perceived behavioral control, intention, and self-reported actual behavior, but it was ineffective for improving attitude strength, subjective norms, and role identity. The results provide useful information for physical education teachers interested in promoting students' positive attitudes towards physical activity.

Relationships between self-regulation skills and physical activity and fruit and vegetable consumption in obese adults: mediation of mood and self-efficacy

In cognitive-behavioral treatments for obesity, self-regulation is thought to be a strong predictor of behavioral change, but it is rarely directly measured in intervention research. Thus, how self-regulation interacts with other psychological variables regarding treatment effects is largely unknown. In this preliminary field study, self-regulatory skills were directly measured and were found to be significantly associated with both volume of exercise and fruit and vegetable consumption in severely obese adults (N=116) enrolled in a behavioral weight management program. Significant partial and complete mediation of the relationship between self-regulation for physical activity and physical activity, and self-regulation for appropriate eating and fruit and vegetable intake, respectively, were found by reported negative mood. Self-efficacy was not found to be a significant mediator of these relationships. The bivariate relationship between baseline scores of self-regulation for physical activity and self-regulation for appropriate eating was significant (r = .46), which supported the premise that self-regulation is a trait-like personal characteristic. Volume of exercise and fruit and vegetable consumption significantly predicted weight loss over 6 months (R2 = .35). Results were consistent with the few laboratory-based findings available and, after replication, may extend theory related to obesity treatment.     

Relations of age with changes in self-efficacy and physical self-concept in preadolescents participating in a physical activity intervention during afterschool care

An inference from Piaget's theory of cognitive development suggests that preadolescents of different ages who participate in a physical activity intervention may respond differently on measures of their physical self and self-efficacy, so a field investigation was conducted to assess effects. In a sample of 105 children ages 8 to 12 yr. (42% boys, overall M(age) = 10.1 yr., SD = 0.9), participation in a physical activity intervention during afterschool care, based on social cognitive theory and incorporating instruction in self-management and self-regulatory skills, was associated with significant improvements in measures of exercise-related self-efficacy, perceived physical appearance, and physical self-concept over 12 wk. Analyses suggested, however, no difference in changes on these factors was associated with participants' age or children being in either the concrete operations or formal operations stage of cognitive development. After replication, implications for design of physical activity interventions for preadolescents were suggested.     

Building a multiple modality, theory-based physical activity intervention: The development of CardiACTION!

OBJECTIVES: Despite the widely acknowledged benefits of regular physical activity (PA), specific goals for increased population levels of PA, and strongly recommended strategies to promote PA, there is no evidence suggesting that the prevalence of PA is improving. If PA intervention research is to be improved, theory should be used as the basis for intervention development, participant context or environment should be considered in the process, and intervention characteristics that will heighten the likelihood of translation into practice should be implemented (e.g., ease of implementation, low human resource costs). The purpose of this paper is to describe the implementation of the aforementioned concepts within the intervention development process associated with CardiACTION an ongoing randomized 2 × 2 factorial trial. METHODS: The Ecological Model of Physical Activity integrated with Protection Motivation Theory was used to inform the design of the interventions. This integrated model was selected to allow for the development of theory-based individual, environmental, and individually + environmentally targeted physical activity interventions. All intervention strategies were matched to proposed mediators of behavior change. Strategies were then matched to the most appropriate interactive technology (i.e., interactive computer session, automated telephone counseling, and tailored mailings) delivery channel. CONCLUSIONS: The potential implications of this study include determining the independent and combined influence of individual and environment mechanisms of behavior change on intervention effectiveness. In addition, all intervention models are developed to be scalable and disseminable to a broad audience at a low cost.     

Internet-delivered behavioral intervention to increase physical activity in persons with multiple sclerosis: Sustainability and secondary outcomes

Physical activity is associated with many benefits, but persons with multiple sclerosis (MS) are less physically active than the general population. There is a critical need for research on methods of increasing and sustaining the physical activity levels of this population. This randomized controlled trial examined the efficacy of an Internet-delivered and theory-based behavioral intervention that was supplemented with video coaching for increasing and sustaining physical activity over time in persons with MS. Physically inactive, ambulatory persons with MS (N?=?45) were randomly assigned to intervention (n?=?22) or control (n?=?23) conditions and completed a battery of questionnaires before, after, and three months after a 12-week intervention period. Data analyses were conducted in PASW 18.0. Partial eta squared ([Formula: see text]) effect size indicated that there was a large, statistically significant condition-by-time interaction on physical activity ([Formula: see text]). Cohen's d effect sizes indicated that the intervention group had a large increase in physical activity after the 12-week trial (d?=?.98) that was sustained over a three-month follow-up (d?=?.79). The current study supports the efficacy of a behavioral intervention for increasing and sustaining physical activity in a sample of persons with MS.     

Adherence to exercise and physical activity as health-promoting behaviors: Attitudinal and self-efficacy influences

In this review, we consider the extant literature dealing with the influential roles of self-efficacy and attitudes in adherence to exercise. In so doing, we provide a brief overview of the tenets of each theory followed by the primary review of each model as it has been applied to exercise behavior in both diseased and asymptomatic population. Next, we offer some recommendations for the practical application of these theoretical models in facilitating physical activity participation. Finally, we conclude with a summary of our approach.     

Attachment relationships and physical activity in adolescents: The mediation role of physical self-concept

ObjectivesBased on the integration of attachment and physical self-perception perspectives, the present study examined links between adolescents' engagement in physical activity and their attachment relationships with mothers, fathers, and friends, respectively, and assessed the potential mediation role of physical self-perception in this link.Design and methodsUsing a cross-sectional design, questionnaire data was obtained from 767 adolescents (49% boys, M_age = 12.92, SD = .86) and structural equation modeling was used to examine relationships among variables.ResultsAttachment security with parents and friend was associated with higher levels of physical activity. There was partial support of the mediation role of physical self-perception, as adolescents who were securely attached to mother and friend perceived themselves as having better physical condition, which in turn predicted greater engagement in physical activity. The mediation role of physical self-perception between mother attachment and PA was stronger for female adolescents. Secure attachment to father had a direct positive effect on physical activity. The direct effect was strongest for male adolescents.ConclusionsOur findings highlight the importance of relationship-based intervention strategies to enhance and maintain healthy regular physical activity among adolescents.     

A self-regulation-based intervention to increase physical activity in cancer patients

The study examined whether a behavior-change intervention focusing on self-regulatory strategies and emphasizing role model support increases physical activity (PA) among insufficiently active (not meeting PA guidelines of 150 min/week) cancer patients. Ambulatory cancer patients [N = 72; 54% female; M = 56 years, SD = 12.34; most with breast or colon cancer (34, 15%)] were enrolled in the MOTIVACTION-study, a 4-week intervention (1-hr counseling, followed by weekly phone calls), with pretest (T1), posttest (T2) and a 10-week follow-up (T3). Participants were randomized to either an exercise or to a stress management intervention (active control). The exercise intervention emphasized self-regulatory strategies (e.g. action- and coping planning and self-monitoring); patients were also encouraged to contact a physically active same-sex role model as a potential exercise partner. The active control condition consisted of coping and relaxation techniques. Sixty-seven patients remained in the study and completed the SQUASH assessment of PA and a measure of perceived stress. PA was validated by Actigraph accelerometry. At T2, 46% of the patients in the exercise group and 19% of stress management patients increased their activity levels to meet PA guidelines (>150 min/week; χ²(1) = 5.51, p = .019). At T3, participants in the exercise intervention maintained their exercise level (46%), but also 31% of the stress management patients met the guidelines. All patients reported reductions in perceived stress. Additional analyses comparing patients in the exercise group by role model contact (63% realized contact) revealed that those who had contact with their role model were significantly more likely to adhere to the recommended guidelines (T2:50%; T3:64%) compared to those who did not have contact with a role model (T2:39%; T3:15%), suggesting the potential of mobilizing role model support to facilitate PA. In sum, cancer patients may not only benefit from an exercise intervention emphasizing self-regulation, but also from stress management, regarding both reducing stress and increasing PA.     

Spontaneous and experimentally induced action planning and coping planning for physical activity: A meta-analysis

ObjectivesThe main objective of this review was to provide summary effects for spontaneous and experimentally induced action planning (AP) and coping planning (CP) for physical activity (PA). These summary effects were then used to test key theoretical postulates using meta-analytic path analysis, and examine possible boundary conditions via moderation analyses.DesignThis review employed a quantitative research synthesis design.MethodUsing the method of Lipsey and Wilson (2001), fixed- and random-effects meta-analysis was performed on over 150 effect sizes from 23 correlational and 21 experimental studies. The method of Viswesvaran and Ones (1995) was used to test two mediation models using the correlational meta-analytic data. Group comparisons and meta-regression were used to test moderation.ResultsAmong the correlational studies, findings indicated a medium-to-large summary effect of spontaneous AP (φ = .41) and CP (φ = .38) on PA. Among the experimental studies, results revealed a small-to-medium summary effect (φ = .24) when comparing all experimental conditions versus all controls and a medium-to-large summary effect (φ = .37) when comparing purely planning conditions versus neutral controls. Support was found for AP and CP as partial mediators in the relation between intention and PA. Numerous significant moderators emerged.ConclusionThis review offers the first meta-analytic estimates of both spontaneous and experimentally induced AP and CP for PA, while supporting the role of both spontaneous AP and CP as mediators in both a multiple and sequential mediation model. Relevant moderators will serve to inform future research in this area.     

Resources for health: a primary-care-based diet and physical activity intervention targeting urban Latinos with multiple chronic conditions.

OBJECTIVE: The Resources for Health trial evaluates a social-ecologically based lifestyle (physical activity and diet) intervention targeting low-income, largely Spanish-speaking patients with multiple chronic conditions. DESIGN: A randomized controlled trial was conducted with 200 patients recruited from an urban community health center and assigned to intervention and usual care conditions. Intervention involved 2 face-to-face, self-management support and community linkage sessions with a health educator, 3 follow-up phone calls, and 3 tailored newsletters. MAIN OUTCOME MEASURES: Primary outcomes measured at 6-months were changes in dietary behavior and physical activity. Changes in multilevel support for healthy living were evaluated as a secondary outcome. RESULTS: After adjustment for age, sex, language, and number of chronic conditions, significant intervention effects were observed for dietary behavior and multilevel support for healthy lifestyles but not for physical activity. CONCLUSION: The Resources for Health intervention provides an effective and practical model for improving health behavior among low-income, Spanish-speaking patients with multiple chronic conditions.     

Core self-evaluation and career decision self-efficacy: A mediation model of value orientations

This study examined two value orientations (i.e., a doing orientation, or the tendency to commit to work ethic and goals, and a mastery orientation, or the tendency to seek control over outside forces) as mediators in the relationship between core self-evaluation and career decision self-efficacy. Data were collected from 802 Chinese university students and analyzed employing structural equation modeling. Results showed that both doing and mastery orientations fully mediated the relationship between core self-evaluation and career decision self-efficacy. Mastery orientation exhibited a stronger mediating effect on this relationship than did doing orientation. These findings reveal some important mechanisms underlying the role of core self-evaluation in career decision-making processes and offer useful implications for researchers and practitioners.
