Coping Versus Mastery Modeling Intervention to Enhance Self-efficacy for Exercise in Patients with COPD.

The literature suggests self-efficacy is a determinant of physical activity and management of Chronic Obstructive Pulmonary Disease (COPD). The purpose of this study was to (1) test the effects of two vicarious experience interventions, coping versus mastery modeling, on self-efficacy in COPD patients performing a cardiopulmonary exercise test (CPET), and (2) determine the type of self-efficacy most strongly related to physical activity in COPD patients. After a baseline assessment of self-efficacy (task, coping for exercise, coping for breathing, scheduling, and walking) and potential moderators, 120 COPD patients watched a mastery model or coping model CPET video, or received usual care verbal instructions. Then, self-efficacy was assessed, followed by a CPET, and another assessment of self-efficacy. Fitbits tracked participants' step count the week following contact. Repeated measures MANOVAs assessed the intervention effects and multiple regressions assessed the contribution of self-efficacy subtypes to step count. All self-efficacy subtypes improved in the mastery and coping conditions, although greater improvement of self-efficacy for coping with exercise barriers was observed in the coping condition. Self-efficacy did not improve in the control condition and no moderators were identified. Self-efficacy for coping with exercise barriers was the self-efficacy subtype most strongly related to step count. This research suggests modeling is a useful intervention technique to enhance self-efficacy in COPD patients, although coping models may be more beneficial than mastery models for enhancing capability beliefs during complex tasks. Future interventions in COPD patients should target self-efficacy for coping with exercise barriers.

Markers of Early Specialization and Their Relationships With Burnout and Dropout in Swimming.

Empirical evidence directly associating early sport specialization with burnout and dropout is lacking, although a relationship is theorized. Research in this area relies on time-intensive retrospective interviews or questionnaires that generate large amounts of data. The optimal use of these data for assessing early specialization (ES) and its relationship with key criterion variables is unclear. The purpose of this study was to add empirical evidence to the literature regarding ES, burnout, and dropout. This involved examining a large number of hypothesized markers of ES and reducing them to a smaller set useful for predicting burnout and dropout. Survey data were collected from 137 swimmers, age 12-13 years, and their parents, including descriptions of swimmers' sport backgrounds from age 6 until present. Contrary to what was expected, the ES items were not positively related to burnout and dropout. The authors present several possible explanations, including key motivational considerations.

The Relationship of Explicit-Implicit Evaluative Discrepancy to Exercise Dropout in Middle-Aged Adults.

Discrepancies between automatically activated associations (i.e., implicit evaluations) and explicit evaluations of motives (measured with a questionnaire) could lead to greater information processing to resolve discrepancies or self-regulatory failures that may affect behavior. This research examined the relationship of health and appearance exercise-related explicit-implicit evaluative discrepancies, the interaction between implicit and explicit evaluations, and the combined value of explicit and implicit evaluations (i.e., the summed scores) to dropout from a yearlong exercise program. Participants (N = 253) completed implicit health and appearance measures and explicit health and appearance motives at baseline, prior to starting the exercise program. The sum of implicit and explicit appearance measures was positively related to weeks in the program, and discrepancy between the implicit and explicit health measures was negatively related to length of time in the program. Implicit exercise evaluations and their relationships to oft-cited motives such as appearance and health may inform exercise dropout.

Long-term Physical Activity Behavior After Completion of Traditional Versus Fast-track Cardiac Rehabilitation.

BACKGROUND: Despite the health benefits associated with regular physical activity (PA), many cardiac patients fail to maintain optimal levels of PA after completing cardiac rehabilitation (CR). The long-term impact of different CR delivery models on the PA habits of cardiac patients is not completely understood. OBJECTIVE: The purpose of this study is to use a multisensor accelerometer to compare the long-term impact of a traditional versus fast-track CR on the PA of patients with coronary artery disease 6 months after CR entry. METHODS: Forty-four participants attended either traditional (twice a week, 12 weeks; n = 24) or fast-track (once a week, 8 weeks; n = 20) CR. Exercise capacity (ie, 6-minute walk test distance) and PA were assessed at baseline and at 12 weeks and 6 months after CR entry. RESULTS: At 12 weeks, exercise capacity increased significantly in both groups and remained elevated by the 6-month follow-up. Sedentary time decreased from baseline to 12 weeks. However, at 6 months, it was comparable with the baseline level. There was no significant change in any other PA marker (ie, steps/day, time in light and moderate-vigorous PA) over the course of the study. CONCLUSIONS: Findings support the long-term effectiveness of CR on exercise capacity irrespective of the delivery model. However, participation in CR program, whether it be a traditional or fast-track CR exercise program, may not lead to long-term PA behavior change. Thus, CR participants may benefit from structured strategies that promote long-term PA adherence in addition to facilitating exercise capacity improvement.

Moderators of Implicit-Explicit Exercise Cognition Concordance.

Investigating implicit-explicit concordance can aid in understanding underlying mechanisms and possible intervention effects. This research examined the concordance between implicit associations of exercise with health or appearance and related explicit motives. Variables considered as possible moderators were behavioral regulations, explicit attitudes, and social desirability. Participants (N = 454) completed measures of implicit associations of exercise with health and appearance and questionnaire measures of health and appearance motives, attitudes, social desirability, and behavioral regulations. Attitudes significantly moderated the relationship between implicit associations of exercise with health and health motives. Identified regulations significantly moderated implicit-explicit concordance with respect to associations with appearance. These results suggest that implicit and explicit exercise-related cognitions are not necessarily independent and their relationship to each other may be moderated by attitudes or some forms of behavioral regulation. Future research that takes a dual-processing approach to exercise behavior should consider potential theoretical moderators of concordance.

An experimental assessment of the influence of exercise versus social implementation intentions on physical activity during and following pulmonary rehabilitation.

Techniques to increase physical activity among pulmonary rehabilitation patients outside of the rehabilitation context are warranted. Implementation intentions are a strategy used to initiate goal-directed behaviour, and have been found to be useful in other populations. This study compared the long-term effects of exercise and social implementation intentions interventions on objectively measured physical activity in 40 pulmonary rehabilitation patients randomly assigned to condition. Repeated measures ANOVAs found that those in the exercise implementation intentions group took more steps (p = .007) at the end of pulmonary rehabilitation than those in the social implementation intentions group. Improvements attained by the exercise group during the intervention were not maintained 6-months following rehabilitation. Implementation intentions targeting physical activity appear to have positive short term effects on physical activity, although the long term effects are less consistent. This may be due in part to methods used to assess physical activity behaviour.

Personal and situational factors influencing coaches' perceptions of stress.

Coaching has been recognised as a demanding occupation, associated with a range of stressors. The extent to which coaches perceive stress is likely to be influenced by various personal and situational factors. The purpose of this study was to identify coaches' levels of perceived stress and examine the personal and situational factors that may influence coaches' perceptions of stress. In total, 502 coaches working with university, college, Canada Games, and/or nationally identified athletes completed this study. Coaches completed an online survey, which included questions regarding demographics, work/job-related considerations, and aspects relating to their contract. Coaches also completed the Perceived Stress Scale (Cohen, Kamarck, & Mermelstein, 1983). Overall coaches indicated slightly below average levels of perceived stress (M = 15.13 out of 40) compared with norm-values (Cohen & Janicki-Deverts, 2012). Demographic factors, job-related characteristics, and certain aspects of their contract were associated with coaches' perceptions of stress. In particular, unclear expectations, long-working hours (>40), lack of agreed evaluation criteria, higher salaries, and a lack of social support were related to higher perceptions of stress. As such, the findings of the current study indicate that a reduction in perceived stress is likely to be achieved through a multifaceted approach that addresses multiple factors associated with coaching.

Visual representations of single- and multi-sport participation in a youth swimming sample: Implications for definitions and discussions of early specialization.

Academic literature and sport policy documents have cited concerns about an increasing prevalence of early sport specialization, with associated burnout, dropout, and injury. However, evidence to support such statements is limited. Definitions of early specialization vary, but a common criterion is continued participation in a single sport, prior to adolescence. We explored the prevalence of single-sport participation and other patterns of sport involvement from ages 6-12 in a Canadian swimming sample using retrospective longitudinal methods. Parents of 236 competitive swimmers (ages 12-17) completed surveys on their children's sport backgrounds, including the number of sports participated in annually from age 6-12. A cluster heat map elucidated single- and multi-sport patterns over time. Mixed analyses of variance tested for differences by gender and club type. Fourteen percent of our sample showed stable participation in either one sport or multiple sports per year over time, 25% decreased their annual number of sports, and 60% increased. This trend of increasing, rather than decreasing the number of sports in their annual activity roster when approaching age 12 was particularly pronounced for girls. Only 10 participants (4% of the sample) consistently engaged in a single sport each year from age 6-12. Summer (seasonal) swimmers consistently did more sports than year-round swimmers. Overall, our findings showed highly idiosyncratic longitudinal patterns of sport participation that did not easily conform to current sport activity guidelines. We also found similar idiosyncrasy in an ad-hoc analysis of participants who had dropped out of swimming a year later. If single-sport participation is considered a key criterion for defining early specialization, our findings suggest the prevailing narrative around early specialization may be overstated in relation to the number of single-sport athletes. Alternatively, other components of early specialization may be more prevalent and deserving of attention due to possible associations with harmful outcomes.

Exploring the relationship between socioeconomic status, control beliefs and exercise behavior: a multiple mediator model.

The purpose of this study was to examine the relationship between control beliefs, socioeconomic status and exercise intentions and behavior. Specifically, we examined whether distal and proximal control beliefs mediated the association between socioeconomic status and exercise intentions and behavior. A one time, cross sectional mail out survey (N = 350) was conducted in a large urban Canadian city. Distal (i.e., personal constraints) and proximal (i.e., scheduling self-efficacy) control beliefs mediated the association between socioeconomic status and exercise, explaining approximately 30% of the variance. Proximal control beliefs (i.e., scheduling self-efficacy) partially mediated the association between socioeconomic status and intentions, with the models explaining approximately 50% of the variance. Compared to individuals with lower socioeconomic status, individuals with higher socioeconomic status reported more exercise and stronger intentions to exercise. This was at least partly because higher socioeconomic status respondents reported fewer barriers in their lives, and were more confident to cope with the scheduling demands of exercise.

Pulmonary rehabilitation in chronic obstructive pulmonary disease: predictors of program completion and success.

Although participation in pulmonary rehabilitation (PR) improves the health outcomes in patients with Chronic Obstructive Pulmonary Disease (COPD), there are insufficient resources to provide PR to all patients with COPD. Thus, predicting which patients are at risk for drop-out and non-response to rehabilitation is necessary in order to optimize limited resources. This study examined which patient characteristics are predictive of PR drop-out and non-response. 814 patients with COPD took part in standard out-patient PR for 8 weeks. Demographic and standard clinical data were collected before the rehabilitation program had started. Data was analyzed retrospectively to determine if baseline patient characteristics could predict drop-out and non-response to rehabilitation. Drop-out was defined as participation in less than 50% of the rehabilitation sessions. Non-response was defined as improvement less than 4% on the St. George's Respiratory Questionnaire (SGRQ). A discriminant function analysis identified age, smoking history, and health status as predictors of patient drop-out, p < .0001, with younger, current smokers and patients with lower health status being at risk for drop-out. No variables measured significantly predicted who those at risk would be for non-response to rehabilitation, p > .05. Pulmonary function data did not predict drop-out or non-response to PR. These findings indicate that perceived impairment (i.e., health status) is more likely to influence completion of rehabilitation than actual pulmonary impairment and that demographic and standard clinical data do not adequately predict patient drop-out and non-response to rehabilitation.

Strength of messaging in changing attitudes in a workplace wellness program.

The potential benefits of workplace wellness programs are limited by low participation rates of employees, which could be due in part to ineffective persuasion by program providers. This study uses the Elaboration Likelihood Model, as a guiding theory in mixed methods research, to investigate feedback messages about physical activity delivered in a workplace wellness program. This study uses questionnaire and interview data from 32 employees to determine if personally relevant health messages are associated with either positive or negative responses to the messages and subsequent attitude change. General feedback is more appreciated by those who are less fit but are not effective in changing attitudes toward physical activity. Individually targeted messages result in a significant positive attitude change for participants responding positively to the messages. This suggests that individualized health promotion messages provide a stronger argument for individuals, thus increasing the likelihood of attitude change.

An examination of psychosocial correlates of exercise tolerance in cardiac rehabilitation participants.

This study explored the influence of psychosocial factors on an important prognostic indictor among heart patients, exercise tolerance (ET). Prior to attending cardiac rehabilitation (CR), 100 men and 24 women completed a survey assessing social support and self-efficacy for exercise in CR followed by an ET test (ETT) measured in metabolic equivalents (METS) 1 month later. Regression analyses showed that age was the strongest predictor of METS, but that income and the psychosocial variables also significantly impacted on METS. Overall, 50% of the variance in METS was explained by the predictor variables. These results show that psychosocial factors affect the ET of heart patients. Future research should examine the prognostic role of these psychosocial factors as they affect ET as well as their influence on behavioral mechanisms such as exercise.

A feasibility pragmatic clinical trial of a primary care network exercise and education program for people with COPD.

BACKGROUND: Pulmonary rehabilitation is an important component of chronic disease management in chronic obstructive pulmonary disease (COPD) and has been shown to improve shortness of breath, exercise capacity, quality of life, and decrease hospitalizations. However, pulmonary rehabilitation capacity is low. Primary care may be an effective method for delivering disease management services to this population. The objective of this feasibility pragmatic clinical trial was to evaluate enrollment and completion of a primary care network exercise and education program for people with COPD. METHODS: COPD patients (N = 23; mean age = 65 ± 9 years; FEV1 = 68 ± 20% predicted) were recruited after referral to a primary care network exercise program in Edmonton, Alberta. Participants self-selected either an 8-week 16-session supervised exercise program or an 8-week unsupervised exercise program where they received three visits with an exercise specialist. Both groups self-selected education sessions with clinicians for disease management support. Referrals, completion, and program outcomes (physical activity, exercise capacity and health status) were measured before (T1), immediately after (T2), and 8 weeks following the program (T3). RESULTS: Forty-three referrals were received in 10 months, where a minimum of 50 was required in order for the program to be considered feasible. Twenty-three participants provided baseline data, and twenty participants started the exercise program (10 in each exercise group), 16 of which completed the exercise program (80%). On average, 48% of the recommended education sessions were completed by participants. CONCLUSIONS: Enrollment into a COPD exercise and education program in a primary care network was low indicating the need for improved referral processes from physicians. Completion rates by participants were adequate for exercise but not education. The low referral rate and the lack of enrollment in COPD education by the patients indicate that a large-scale trial of the program as designed is not feasible.

Automatic associations of breast cancer and heart disease with fruit and vegetables and physical activity.

OBJECTIVES: This exploratory research examined if breast cancer or heart disease is automatically associated with physical activity compared to fruit and vegetable stimuli; if reading messages about reducing risk of breast cancer or heart disease through physical activity and fruit and vegetable consumption would affect automatic associations; and if automatic associations were related to intentions to be physically active or consume fruit and vegetables. METHODS: Participants were 80 women who completed pretest measures of automatic associations, then read a breast cancer, heart disease, or control message, followed by posttest measures. RESULTS: There was a significant association of breast cancer-related words with fruit and vegetables compared to physical activity. Heart disease was also more strongly associated with fruit and vegetables than physical activity at pretest but not at posttest. There were no other significant findings. CONCLUSION: This research highlights that fruit and vegetables rather than physical activity are more strongly associated with perceptions of breast cancer and heart disease. Automatic associations are an attitudinal construct, and the strength of association between fruit and vegetables, rather than physical activity, indicates how messages may be processed.

Reciprocal relationships between self-efficacy, outcome satisfaction, and attendance at an exercise programme.

OBJECTIVES: The objectives of this study were to (i) investigate directional influences of self-efficacy, outcome satisfaction, and attendance during an exercise programme and (ii) examine the predictive capabilities of self-efficacy and outcome satisfaction on participant dropout. METHODS: Adults aged 35-65 years were recruited to a 12-month exercise programme. Self-efficacy was collected at baseline, three, six, nine, and 12 months, and outcome satisfaction at the same time-points except baseline. Cross-lagged panel analyses and logistic regression analyses were conducted to examine the primary and secondary objectives, respectively. RESULTS: Coping and scheduling self-efficacy had stronger reciprocal relationships with outcome satisfaction than task self-efficacy, although the strength of these relationships varied across time. Initially, task self-efficacy predicted programme attendance. Midway through the programme, outcome satisfaction predicted attendance, and by the end of the programme, coping self-efficacy was the strongest predictor of attendance. Self-efficacy and outcome satisfaction did not predict programme dropout. CONCLUSIONS: The results support the reciprocal relationship between outcome satisfaction and scheduling and coping self-efficacy and highlight the importance of sequentially targeting different beliefs and skills to facilitate successful initiation and maintenance of exercise behaviour. Statement of contribution What is already known on this subject? Self-efficacy and outcome satisfaction are related to exercise behaviour. The relationship between self-efficacy and outcome satisfaction are typically considered unidirectional. The longitudinal relationships among self-efficacy, outcome satisfaction, and physical activity participation are unclear. What does this study add? Outcome satisfaction had reciprocal relationships with both coping and scheduling self-efficacy for exercise. The importance of self-efficacy and outcome satisfaction to exercise attendance changes over time. Task self-efficacy was the strongest predictor of initial programme attendance. Midway through the programme, outcome satisfaction and task self-efficacy were the strongest predictors of attendance, and by the end of the programme, coping self-efficacy was the strongest predictor.

Taking a hard look at the Heart Truth campaign in Canada: A discourse analysis.

The Canadian Heart and Stroke Foundation launched the Heart Truth campaign to increase women's awareness of heart disease. However, little is known about how such campaigns intersect with broader understandings of gender and health. This discourse analysis examined the construction of gender, risk, and prevention within campaign material. Two primary discourses emerged: one of acceptable femininity, which outlines whose risk, survivorship, and prevention matters, and another of selfless prevention. Women of diverse ethnic, sexual, and socio-economic background were largely absent. Prevention was portrayed as a personal choice, eclipsing conversations about social determinants of health and the socio-political context of heart disease.

Investigating relationships between ancestry, lifestyle behaviors and perceptions of heart disease and breast cancer among Canadian women with British and with South Asian ancestry.

BACKGROUND: Ethnic minority groups including Asians in Canada have different knowledge and perceptions of heart disease and breast cancer compared with the ethnic majority group. AIM: Examine relationships between perceptions of heart disease and breast cancer, and lifestyle behaviors for Canadian women with British and with South Asian ancestry. METHODS: Women with South Asian ( n = 170) and with British ( n = 373) ancestry ( Mage = 33.01, SD = 12.86) reported leisure time physical activity, intended fruit and vegetable consumption, disease perceptions (ability to reduce risk, control over getting the diseases, and influence of family history), and demographic information. Mann-Whitney tests and multiple hierarchical linear regressions were used to examine the relationships between lifestyle behaviors and disease perceptions, with ancestry explored as a possible moderator. RESULTS: Participants with South Asian ancestry believed they had greater ability to reduce their risk and have control over getting breast cancer than participants with British ancestry. Family history influences on getting either disease was perceived as higher for women with British ancestry. Age was positively related to all three perceptions in both diseases. Intended fruit and vegetable consumption was positively related to perceptions of ability to reduce risk and control of both diseases, but was stronger for women with South Asian ancestry regarding perceptions of breast cancer. Leisure time physical activity was positively related to perceptions of control over getting heart disease for women with British ancestry. CONCLUSIONS: Women's disease perceptions can vary by ancestry and lifestyle behaviors. Accurate representation of diseases is essential in promoting effective preventative behaviors.

Believability of messages about preventing breast cancer and heart disease through physical activity.

BACKGROUND: The purpose of this research was to examine the relationships of self-reported physical activity to involvement with messages that discuss the prevention of heart disease and breast cancer through physical activity, the explicit believability of the messages, and agreement (or disagreement) with specific statements about the messages or disease beliefs in general. METHODS: A within subjects' design was used. Participants (N = 96) read either a breast cancer or heart disease message first, then completed a corresponding task that measured agreement or disagreement and confidence in the agreement or disagreement that 1) physical activity 'reduces risk/does not reduce risk' of breast cancer or heart disease, 2) that breast cancer or heart disease is a 'real/not real risk for me', 3) that women who get breast cancer or heart disease are 'like/not like me', and 4) that women who get breast cancer or heart disease are 'to blame/not to blame'. This task was followed by a questionnaire measuring message involvement and explicit believability. They then read the other disease messages and completed the corresponding agreement and confidence task and questionnaire measures. Lastly, participants completed a questionnaire measuring physical activity related attitudes and intentions, and demographics. RESULTS: There was no difference in message involvement or explicit believability of breast cancer compared to heart disease messages. Active participants had a higher confidence in their agreement that physical activity is preventive of heart disease compared to breast cancer. Multinomial regression models showed that, in addition to physical activity related attitudes and intentions, agreement that physical activity was preventive of heart disease and that women with heart disease are 'like me' were predictors of being more active compared to inactive. In the breast cancer model only attitudes and intentions predicted physical activity group. CONCLUSIONS: Active women likely internalized messages about heart disease prevention through physical activity, making the prevention messages more readily available within memory, and active women may therefore process such information differently. The study of how health-related beliefs are created and are related to perceptions of prevention messages is a rich area of study that may contribute to more effective health promotion.

The importance of exercise self-efficacy for clinical outcomes in pulmonary rehabilitation.

OBJECTIVE: Pulmonary rehabilitation (PR) improves functional exercise capacity and health status in people with chronic obstructive pulmonary disease (COPD), although these outcomes are often not maintained following PR. Self-efficacy is a precursor to outcomes achievement, yet few studies have examined the importance of self-efficacy to outcome improvement during PR, or how it develops over time. Further, the contribution of exercise-specific self-efficacy to outcomes in PR is unknown. The aims of this study were to determine (a) whether baseline exercise self-efficacy predicts PR attendance and change in functional exercise capacity and health status over PR, and (b) if exercise self-efficacy changes with PR. METHOD: Fifty-eight out of 64 patients with COPD completed PR and assessments of exercise self-efficacy (task, coping, scheduling), the 6-minute walk test (6MWT), and St. George's Respiratory Questionnaire (SGRQ) at the beginning and end of PR. Analyses were conducted to predict attendance, and change in 6MWT and SGRQ, while controlling for baseline demographic and clinical indicators. Change in 6MWT, SGRQ, and self-efficacy with PR was also examined. RESULTS: Clinically significant increases in the 6MWT and SGRQ were achieved with PR. Stronger task self-efficacy predicted better attendance, while stronger coping self-efficacy predicted greater 6MWT improvement. No variables predicted SGRQ change. Scheduling self-efficacy significantly improved with PR, whereas task and coping self-efficacy did not. CONCLUSION: Baseline exercise self-efficacy appears to be a determinant of rehabilitation attendance and functional exercise improvement with PR. Clinicians should evaluate and target exercise self-efficacy to maximize adherence and health outcome improvement with PR. (PsycINFO Database Record
