Antecedents of self identity and consequences for action control: An application of the theory of planned behaviour in the exercise domain

ObjectivesTo study whether exercise action control profiles should be usefully extended to include exercise identity. Further, this study investigated theory of planned behaviour antecedents of exercise identity.DesignProspective data from 413 undergraduate students (M age = 21.4; 73.5% females).MethodValidated questionnaires were used at baseline and follow-up two weeks later to assess exercise behaviour, intention, self-identity, and theory of planned behaviour concepts. Research questions were analysed using chi-square analysis, discriminant function analysis and structural equation modelling. Results were interpreted using p-values and effect sizes.ResultsThere was a higher proportion of exercise intenders in the strong exercise identity group than in the weak exercise identity group (81.9% vs. 14.5%) and a higher proportion of successful intenders in the high exercise identity group than in the low exercise identity group (45.5% vs. 18.2%). Affective attitude and perceived behavioural control (PBC) were the most important predictors of exercise action control. Regarding the antecedents of identity, results showed significant and small-sized associations for baseline affective attitude and perceived behavioural control and large-sized association for baseline self-identity.ConclusionExercise identity should be usefully employed to understand exercise motivation and action control. Affective attitude and perceived behavioural control facilitate action control and exercise identity development and are suggested to be taken into account when developing exercise interventions.     

Group cohesion and adherence in unstructured exercise groups

ObjectivesPrevious research has reported a positive relationship between perceptions of cohesion and adherence within structured exercise settings. Given that the social determinants of adherence can vary across situations, this study aimed to examine the cohesion–adherence relationship in unstructured exercise settings.DesignThis study employed a cross-sectional design.MethodsYoung adults (N = 125) recalled an unstructured exercise group where they had been participants, and then rated their perceptions of cohesion with respect to that group as well as reported the number of times/month they had been active in that group.ResultsRegression results revealed that cohesion was significantly related to adherence. Individuals who reported higher levels of task and lower levels of social cohesion, with both dimensions of cohesion reflecting the perceptions of the group as a totality, attended more sessions.ConclusionsThese findings extend research reporting that the cohesiveness perceived in a structured exercise group is related to adherence. However, there were two findings that were not consistent with previous research. The failure of the task dimension associated with satisfying personal needs and objectives to emerge as well as the emergence of a negative relationship with one of the social dimensions of cohesion suggest that the relationship between cohesion and adherence may play out differently in an unstructured versus structured setting with young adults.     

Perceived self-regulation of exercise goals and interfering goals among regular and irregular exercisers: a life space analysis

ObjectivesTo investigate whether adults self-classified as regular and irregular exercisers tend to differentially perceive the self-regulation of their exercise goals (a between groups comparison) and whether the groups’ differ in their self-regulatory perceptions of an exercise goal versus a goal that strongly interferes with exercise (a within groups comparison).DesignsCross-Sectional Survey.MethodsCollege students (N=399, 66% female), who were either regular or irregular exercisers, completed the Goal Systems Assessment Battery [GSAB; Karoly, P., & Ruehlman, L. S. (1995). Goal cognition and its clinical implications: Development and preliminary validation of four motivational assessment instruments. Assessment, 2, 113–129] for the goal of exercise and for a self-selected interfering goal. The GSAB gauges how individuals evaluate multiple functional components of self-regulation.ResultsA doubly multivariate MANOVA revealed a significant interaction between exercise regularity and goal type. Irregular exercisers manifested a pattern of goal regulatory thinking favoring their interfering goal relative to their exercise goal with respect to its value and the extent of their monitoring, planning, social comparison, and self-rewarding their progress toward that goal. Regular exercisers tended not to make such regulatory distinctions.ConclusionsAlthough life pursuits identified as interfering with exercise (e.g. academic goals) generally require more of a psychological investment than engaging in exercise, regular exercisers tend to construe their physical activity goals in a manner that closely matches their ratings of competing life aspirations. A dual focus on exercise goals and their aspirational rivals may inform motivational theory and intervention.     

Using self-determination theory to examine the motivational correlates and predictive utility of spontaneous exercise implementation intentions

ObjectivesThis study adopted a self-determination theory approach to explore the correlates of a measure of spontaneous implementation intentions; designed to allow for volition in planning when, where, and how to exercise. The study further explored the relationship between spontaneous implementation intentions and measures of behavioural regulation, in explaining exercise behaviour.DesignThe initial sample of 253 (99 males, 153 females) Canadian University College students was reduced to 162 participants (63 males, 99 females) after three phases of data collection. Measures of spontaneous implementation intentions and the Behavioural Regulation in Exercise Questionnaire were completed during the first phase of data collection. Actual exercise behaviour was assessed two, then three weeks later.ResultsA standard regression analysis revealed that identified regulation significantly predicted spontaneous implementation intentions, accounting for 36% of the variance. A hierarchical regression analysis revealed that after the first step, identified regulation made a significant contribution accounting for 35% of the variance in exercise behaviour. The addition of spontaneous implementation intentions significantly increased the prediction of exercise by 8%. An investigation of the beta coefficients revealed that spontaneous implementation intentions reduced the effects of identification from .50 to .26 after taking into consideration the effects of spontaneous implementation intentions in the second step of the analysis. The indirect effect of identification on exercise via spontaneous implementation intentions was statistically significant (z=3.88, p<.05).ConclusionsPeople who exercise for more self-determined reasons are more likely to spontaneously form implementation intentions, and because implementation intentions have motivating effects, they might lead to more self-determined behaviour.     

Perceptions of the behavioral influence of goals: A mediational relationship to exercise

Abstract

In the present study, it is argued that a more fundamental approach is necessary for the study of exercise goals and exercise behavior if we are to understand their relationship. The specific purposes of the investigation were to a) examine the relationships between perceptions of the behavioral influence of goals, moderators of goal influence (i.e., goal clarity) and perceptions of required exercise behavior (frequency and intensity), (b) examine changes that occurred over time to measures of goal-related variables and (c) describe various personal exercise goals and related action plans to achieve goals. Ninety-nine healthy adults in intermediate level university fitness classes were volunteers in this prospective study. The present study revealed that exercisers have multiple goals and action plans and are also knowledgeable about the specific behavioral strategies and exercise behaviors required to attain these goals. Also, the clarity, commitment, and perceived behavioral influence of goals increased as adherers gained experience with the exercise program. Finally, perceptions of the way goals influence behavior was found to mediate the goal clarity-exercise intensity and the goal commitment-exercise intensity relationships at the beginning of the exercise program but not at mid-program. Instead, independent relationships emerged at midprogram between goal clarity and goal influence, goal commitment and goal influence, goal clarity and exercise intensity, goal commitment and exercise intensity, and goal influence and exercise intensity. Results an discussed in terms of the complex and changing nature of the perceptions people hold of their goals and how these goals influence their exercise.     

Self-control strength and physical exercise: An ecological momentary assessment study

ObjectiveWe tested predictions made by the self-control strength model on a day level using ecological momentary assessment methodology. The study examined the relationship between self-control strength and physical exercise in participants who intended to exercise on a regular basis. We hypothesized that individuals would exercise more on days when their self-control strength was high than on days when their self-control strength was low and that trait self-control would moderate this relationship.MethodsN = 63 students aged between 19 and 32 years participated in the study. Self-control strength and physical exercise were assessed daily over a period of 20 days with an electronic diary.ResultsMultilevel analyses revealed that the level of self-control strength was positively associated with physical exercise (p = 0.01), and this relationship was stronger in individuals with low trait self-control than in those with high trait self-control (interaction effect: p = 0.03).ConclusionThese findings highlight the interplay between momentarily fluctuating variables such as self-control strength and dispositional variables such as trait self-control in the prediction of physical exercise.     

Women's exercise identity increases after a 16-week exercise RCT and is linked to behavior maintenance at follow-up

BackgroundRegular exercise is critical for disease prevention, but adherence to public health guidelines is poor. Exercise identity is purported to be associated with exercise behavior maintenance, but the extant literature is largely cross-sectional and of low/modest quality.PurposeTo examine change in exercise identity after completion of a supervised exercise intervention, as well as associations between change in exercise identity and exercise maintenance at 6-months follow-up.MethodsN = 276 insufficiently physically active women were randomized to a 16-week, supervised exercise training intervention with 4 conditions fully crossed on intensity (vigorous/moderate) and duration (long/short). Exercise identity was measured pre- and post-intervention and assessments of exercise motivation and behavior frequency were collected at 6-months post-intervention follow-up.ResultsOn average, participants experienced a statistically significant change in exercise identity over the course of the intervention, t (128) = 7.94, p < .001, but identity change scores did not differ across training conditions, p = .91. Identity change was significantly positively related to changes in other theory-informed, motivation-based determinants of exercise, and predicted an additional 16.17 min of exercise per week, on average, at follow-up, b = 16.76, t (103) = 2.30, p = .023.ConclusionsParticipants experienced increased self-identification with exercise after 16-weeks of training, but training volume did not influence the amount of identity change. As expected, greater change in exercise identity was associated with higher levels of exercise behavior at 6-months post-intervention follow-up (ClinicalTrials.gov number NCT02032628 ).     

Bridging the intention–behaviour gap: Planning,self-efficacy,and action control in the adoption and maintenance of physical exercise

Although some people may develop an intention to change their health behaviour, they might not take any action. This discrepancy has been labelled the “intention–behaviour gap.” Detailed action planning, perceived self-efficacy, and self-regulatory strategies (action control) may mediate between intentions and behaviour. This was examined in a longitudinal sample of 307 cardiac rehabilitation patients who were encouraged to adopt or maintain regular exercise. At the first time point, the predictors of intention and intention itself were assessed. Two months and four months later, the mediators and outcomes were measured. Results confirmed that all the three factors (planning, maintenance self-efficacy, and action control) served to mediate between earlier exercise intentions and later physical activity, each of them making a unique contribution. The results have implications for research on the “intention–behaviour gap,” and indicate that planning, maintenance self-efficacy and action control may be important volitional variables.     

Predictors of cancer survivors’ response to a community-based exercise program

ObjectiveTo explore the degree to which sociodemographic (i.e., age, sex, ethnicity, weight status, vocational status, marital status), medical (i.e., stage of cancer, treatment status, comorbidity burden), functional (i.e., self-rated health, exercise capacity), cognitive (i.e., exercise self-efficacy beliefs), and behavioural (i.e., program adherence, extra-curricular exercise) factors predicted cancer-related fatigue and quality of life among 224 cancer survivors who participated in the community-based Wellspring Cancer Exercise Program (WCEP).DesignProspective, quasi-experimental single-group repeated measures design.MethodData on predictors and outcomes were collected using self-report and objective measures upon enrollment in the program (week 0), every 10 weeks until program completion (weeks 10, 20, 30), and at 16-weeks follow-up (46 weeks). Data were analyzed using multilevel modeling.ResultsIn general, participants who were working or transitioning to work, rated their health better, and had higher exercise self-efficacy beliefs had lower cancer-related fatigue, and those who rated their health better and had higher exercise self-efficacy beliefs had higher quality of life. Also, there was a significant interaction between time and exercise self-efficacy beliefs for cancer-related fatigue and quality of life such that greater improvements were observed among participants with higher exercise self-efficacy beliefs.ConclusionCancer survivors’ perceptions of their health and their ability to exercise should be fostered to ensure they respond positively to exercise programs in terms of cancer-related fatigue and quality of life.     

Does confrontation with potential goal failure promote self-regulation? Examining the role of distress in the pursuit of weight goals

Implementation intentions planning in advance the situation in which one will act, have been proposed to be an effective self-regulatory technique for changing health behaviour. Encouraging people to receive text message reminders of their implementation intentions should enhance their strength and, thus, it was predicted that this combined approach would be particularly effective in increasing exercise. Participants (N = 155) were randomly allocated to one of five conditions (implementation intentions and SMS, implementation intention, SMS or one of two control groups) then completed self-report measures of exercise behaviour and motivation. Four weeks later, they responded to similar items. Results suggested that the combined intervention increased exercise frequency significantly more than the other strategies including the implementation intention group. It is proposed, therefore, that implementation intention effects can be enhanced via plan reminders.     

The relationship between illness perceptions and panic in chronic obstructive pulmonary disease

BackgroundElevated levels of anxiety and panic are common in respiratory disease. To date the cognitive-behavioural model of panic has been utilised to help explain and manage panic in respiratory disease. This cross-sectional study investigated the relationship between illness perceptions and panic in chronic obstructive pulmonary disease (COPD) within a self-regulatory framework of adaptation to physical illness.MethodsFifty-nine participants with COPD completed questionnaires measuring illness perceptions, anxiety and depression, frequency and severity of panic attacks and impact of disease on daily life and well-being. The percent forced expiratory volume in the first second (FEV₁%) was used as an objective measure of lung function.ResultsHigh levels of clinical anxiety and depression were reported (35% and 19% respectively). Sixty-three percent of participants reported experiencing a panic attack during the previous year and of these 51% during the previous month. Panic was unrelated to level of disease severity. Specific illness perceptions (beliefs relating to illness identity, timeline, consequences and emotional representations) were important in differentiating between panickers and non-panickers.ConclusionsThe results highlight the importance of assessing illness perceptions within the framework of the self-regulatory model to provide an additional theoretical perspective for investigating and managing panic in chronic respiratory disease.     

The role of implicit and explicit components of exerciser self-schema in the prediction of exercise behaviour

ObjectivesThis study investigated implicit and explicit components of exerciser self-schema and their role in the prediction of exercise behaviour. In addition, the effect of implicit and explicit exerciser self-schema on intention to exercise was examined. Moderation and mediation effects involving exerciser self-schema, in both its implicit and explicit forms, were investigated.MethodMembers of fitness centres and other regular exercisers (N = 98, n_males = 37, n_females = 65) completed a written questionnaire to measure explicit exerciser self-schema and exercise intentions. An exercise Implicit Association Test (IAT) was also administered to measure implicit exerciser self-schema. Actual exercise occurrence was measured one week and two weeks following the initial testing phase.ResultsCorrelations indicated that implicit and explicit components of exerciser self-schema were related but distinct constructs. Hierarchical regression analysis revealed that high levels of both implicit and explicit exerciser self-schema improved absolute levels of exercise behaviour. Regression analyses examining the possibility that self-schema moderated the intention–behaviour relationship were not significant for implicit or explicit forms of self-schema. Forced entry regression analyses provided evidence for explicit exerciser self-schema being mediated by intention in its relationship with behaviour.ConclusionsIt is beneficial to consider both implicit and explicit exerciser self-schema when attempting to understand and predict exercise behaviour. Both implicit and explicit exercise self-schema have a direct effect on behaviour, although explicit self-schema also indirectly influences behaviour via intention to exercise.     

Narrative, identity and mental health: How men with serious mental illness re-story their lives through sport and exercise

ObjectivesIt has been suggested that mental illness threatens identity and sense of self when one's personal story is displaced by dominant illness narratives focussing on deficit and dysfunction. One role of therapy, therefore, is to allow individuals to re-story their life in a more positive way which facilitates the reconstruction of a meaningful identity and sense of self. This research explores the ways in which involvement in sport and exercise may play a part in this process.DesignQualitative analysis of narrative.MethodWe used an interpretive approach which included semi-structured interviews and participant observation with 11 men with serious mental illness to gather stories of participants’ sport and exercise experiences. We conducted an analysis of narrative to explore the more general narrative types which were evident in participants’ accounts.FindingsWe identified three narrative types underlying participants’ talk about sport and exercise: (a) an action narrative about “going places and doing stuff”; (b) an achievement narrative about accomplishment through effort, skill or courage; (c) a relationship narrative of shared experiences to talk about combined with opportunities to talk about those experiences. We note that these narrative types differ significantly from—and may be considered alternatives to—dominant illness narratives.ConclusionThis study provides an alternative perspective on how sport and exercise can help men with serious mental illness by providing the narrative resources which enabled participants to re-story aspects of their lives through creating and sharing personal stories through which they rebuilt or maintained a positive sense of self and identity.     

A psychological intervention reduces doping likelihood in British and Greek athletes: A cluster randomized controlled trial

BackgroundCurrent attempts to prevent doping through deterrence and education have had limited success and have been constrained to one country. Targeting psychological variables that have been empirically associated with doping likelihood, intention, or behaviour may help in developing interventions that are effective in preventing doping in sport.ObjectivesGuided by social cognitive theory and empirical research, the main purpose of this research was to develop an anti-doping intervention that targets three psychological variables (i.e., anticipated guilt, moral disengagement, and self-regulatory efficacy) and determine whether it is more effective than an educational intervention in reducing doping likelihood in British and Greek athletes.MethodEligible participants were identified via a screening survey administered to 934 athletes in the United Kingdom and Greece. A total of 19 sport clubs (208 athletes) across the two countries were randomly assigned to either the psychological or the educational intervention. Each intervention consisted of six 1-h sessions delivered to small groups of athletes over 6–8 weeks. Athletes completed measures of doping likelihood, anticipated guilt, moral disengagement, and self-regulatory efficacy pre and postintervention and at a 2-month follow-up.ResultsA multilevel piecewise growth model was used to examine changes in study outcomes. Analysis showed that the psychological intervention was more effective than the educational intervention in reducing doping likelihood from pre to post, but the effects of the two interventions were similar at follow-up. These effects were not affected by country. Both interventions reduced moral disengagement from pre to post, and these effects were maintained at follow-up. The psychological intervention was also more effective than the educational intervention in increasing anticipated guilt from pre to follow-up.ConclusionsTargeting psychological variables in anti-doping interventions should aid our efforts to prevent doping in sport.     

The role of emotion in bridging the intention–behaviour gap: The case of sports participation

ProblemPsychological models of sports participation frequently draw on the Theory of Planned Behaviour (TPB) in order to predict health-behaviour-related intentions. While these models commonly show high predictive power with respect to intention, they often fall short in the prediction of behaviour (the ‘intention–behaviour gap’). The present study contends that integrating emotional processes into TPB can substantially improve the model's predictive power over and above traditional cognitive predictors.MethodIn a longitudinal study structural equation modelling was employed to test a traditional model (based on TPB) and an extended model including emotion associated with the intention to exercise as a mediator variable. A community sample (N = 237) completed a questionnaire measuring the components of a traditional TPB model. Prior to each of 16 expected exercise sessions (over 8 weeks) intention to exercise and emotion associated with the intention were measured.ResultsResults confirmed a substantial increase of 17% in explained variance of exercise frequency and 20% in exercise duration for the extended model. Emotional appraisal of the intention to exercise thus appears to mediate the traditional intention–behaviour relationship, suggesting that emotionally based interventions aimed at increasing sports participation may be helpful.ConclusionIt is concluded that emotion variables should be added to traditional TPB models in order to predict health behaviour more fully.     

Role and group identity and adjustment to the possibility of running group disbandment

Role and group identities are distinct yet related constructs. Both identities may be relevant to exercise yet exercise identity research has focused mostly on exercise role identity.ObjectiveWe examined the relationship between role and group identity among runners. Further, the relationship of runner role and running group identity were examined relative to social cognitive and behavioural outcomes relative to running and the possibility of running group disbandment.DesignAn observational design was used.MethodRunning group members completed measures of runner role and running group identity, self-efficacy for running, and aspects of recent exercise and anticipated reactions to running group disbandment.ResultsRunner role and running group identity showed a small, positive correlation. Runner role identity was associated with self-efficacy for running, vigorous exercise, less group running and adaptive reactions to the possibility of group disbandment. Running group identity was associated with negative self-efficacy, greater percentage of runs being conducted with the group and maladaptive reactions to group disbandment. Runner role and running group identity did not interact in their relationship to exercise-related outcomes.ConclusionsIn the context of running, role and group identities are related but unique variables. Identification as a runner may not only be associated with exercise in the context of the group but may also have protective effects against disruptions to group running. Identification with the running group may compromise exercise in the face of group disbandment.     

Application of the limited strength model of self-regulation to understanding exercise effort,planning and adherence

The limited strength model posits that self-regulatory strength is a finite, renewable resource that is drained when people attempt to regulate their emotions, thoughts or behaviours. The purpose of this study was to determine whether self-regulatory depletion can explain lapses in exercise effort, planning and adherence. In a lab-based experiment, participants exposed to a self-regulatory depletion manipulation generated lower levels of work during a 10 min bicycling task, and planned to exert less effort during an upcoming exercise bout, compared with control participants. The magnitude of reduction in planned exercise effort predicted exercise adherence over a subsequent 8-week period. Together, these results suggest that self-regulatory depletion can influence exercise effort, planning and decision-making and that the depletion of self-regulatory resources can explain episodes of exercise non-adherence both in the lab and in everyday life.     

Cognitive mediation of intervention effects on physical exercise: Causal models for the adoption and maintenance stage

Objective: To investigate how the effects of a group-based intervention program (MoVo-LISA) on exercise behaviour were mediated by cognitive variables. Different causal models mapping the short-term (adoption) and long-term (maintenance) intervention effects were tested using path analyses.

Design: N?=?220 in-patients of a rehabilitation clinic were assigned to an usual care or intervention group (quasi-experimental design). Questionnaire-based assessment was conducted at baseline; discharge; and at six weeks, six months and 12 months post discharge.

Measures: The potential mediator variables were outcome expectations, self-efficacy, strength of goal intention (intention strength), self-concordance, action planning and barrier management.

Results: Observed intervention effects on exercise behaviour (p?<?0.05) were mediated by intention strength at the adoption and maintenance stages, by action planning only at the adoption, and by barrier management only at the maintenance stage. Self-efficacy and outcome expectations were only indirectly involved in these mediations by affecting intention strength and self-concordance.

Conclusion: This is the first study to track the cognitive mediation processes of intervention effects on exercise behaviour over a long time-period by differentiating the adoption and maintenance stages of behaviour change. The findings emphasise the importance of deconstructing intervention effects (modifiability vs. predictive power of a mediator) to develop more effective interventions.
