The purpose of this study was to test a partnered, self-determination theory–informed mobile health intervention called SCI Step Together, using an 8-week randomized controlled trial design. The aim of SCI Step Together is to increase the quantity and quality of physical activity (PA) among adults with spinal cord injury (SCI) who walk. The SCI Step Together program provides PA modules and PA self-monitoring tools and facilitates peer and health coach support. Process, resource, management, and scientific feasibility were assessed, and participants completed questionnaires at baseline, mid-, and postintervention to assess determinants and outcomes of PA. Interviews were conducted to evaluate acceptability. Results suggest that the program demonstrated good feasibility, acceptability, and engagement. The intervention group (n = 11) had greater fulfillment of basic psychological needs and knowledge (p =.05) than the control group (n = 9). There were no significant interaction effects for other outcomes. The SCI Step Together program is feasible and acceptable and efficacious for improving some psychosocial variables. Results may inform SCI mobile health programs. [ABSTRACT FROM AUTHOR]

The purpose of this study was to employ the theoretical domains framework (TDF) to identify behaviour change factors related to leisure-time physical activity (LTPA) in spinal cord injury (SCI) ambulators. A cross-sectional design was employed. Among 43 SCI ambulators, the TDF behaviour change factors were assessed, along with the duration, types, and intensities of LTPA performed over the previous week. The TDF behaviour change factors identified as barriers to LTPA included: knowledge, beliefs about capabilities, coping planning, and goal conflict. Approximately 71.81 mins/day (SD = 75.41) was spent doing LTPA. Participants reported aerobic and resistance training activities, along with several other types of LTPA (e.g., rock climbing). Coping planning, action planning, goal conflict, and skills explained significant variance in time spent on LTPA (R2adjusted = 0.259, p < 0.01), but only action planning uniquely predicted LTPA. Greater use of coping and action planning, lower levels of goal conflict and stronger skills were associated with greater participation in LTPA. These factors will be targeted for a future LTPA-enhancing intervention for SCI ambulators, informed by behaviour change theory. SCI ambulators participate in a surprisingly wide range of LTPA. Rehabilitation specialists can use this list to suggest activities for patients with SCI who ambulate. Barriers to leisure-time physical activity for individuals with spinal cord injury (SCI) who ambulate include lack of knowledge, weak beliefs about capabilities, lack of coping planning, and high goal conflict. Physical activity interventions for individuals with SCI who ambulate should include action and coping planning, goal conflict, and skills. Physical activity interventions should be created systematically using behaviour change theory and involvement of stakeholders throughout the development process. Practitioners can promote skills training in adapted activities like gardening, cycling, and rock-climbing for ambulators with SCI. [ABSTRACT FROM AUTHOR]

Among people with physical disabilities, one of the most frequently-cited barriers to physical activity participation is a lack of basic information on what to do. Likewise, rehabilitation professionals often cite a lack of knowledge about what to recommend or prescribe, as their primary reason for not promoting physical activity to clients with disabilities. The development and implementation of disability-specific physical activity guidelines are important steps toward addressing informational barriers. This paper describes the reasoning behind disability-specific physical activity guidelines, the gold-standard process used to develop disability-specific guidelines for people with spinal cord injury and multiple sclerosis, and the "who, what, and how" of behavioural interventions and messaging to support people with disabilities in achieving physical activity guidelines. Not Applicable. Not Applicable. The needs, values and preferences of people with disabilities must be taken into consideration when undertaking a disability-specific guideline development process. Guidelines can play an important role in physical activity promotion, but behavioural and other interventions are required to address the myriad physical activity barriers faced by people with disabilities. People with and without disabilities can achieve significant fitness and health benefits from activity well below the WHO's 150 minutes/week guideline. Disability-specific physical activity guidelines can alleviate informational barriers for people who want to get active and rehabilitation professionals who want to promote physical activity. Behavioural and other interventions are needed to support people's efforts to achieve physical activity guidelines. A physiotherapist-delivered intervention has shown promise for increasing physical activity in adults with a physical disability. [ABSTRACT FROM AUTHOR]

Objective: Chronic back pain (CBP) is responsible for considerable suffering across the world and is frequently associated with decreased functional capacity, quality of life, and substantial health care costs. Fear avoidance beliefs (FAB) comprise cognitions and fears about the potential for physical activities to produce pain and harm and are common among people with CBP. Collectively, research shows that FAB are frequently associated with low levels of physical activity, poorer work outcomes, and disability. Therefore, the purpose of this systematic review is to systematically locate and synthesize the current evidence regarding the effectiveness of psychological interventions on fear avoidance beliefs and fear avoidance behavior in patients with CBP. Design: A systematic literature search was conducted based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and included the databases Web of Science, PubMed, Cochrane, CINAHL, Medline, and PsycINFO. Results: A total of 5,052 records were identified resulting in 2,448 documents after duplicates were removed. We screened 147 studies full text. Twenty-two studies were included in the qualitative synthesis. FAB were assessed by the Fear Avoidance Beliefs Questionnaire, the Tampa Scale of Kinesiophobia and the Avoidance Exercise Questionnaire. Interventions included cognitive behavior therapy (CBT), psychoeducation (PE), and other psychological approaches like motivational interviewing. Twelve of 22 studies demonstrated significant improvements in FAB for people with CBP who underwent a PE or CBT intervention or a different psychological approach. Conclusion: CBT and PE interventions are mainly used to address FAB among people with CBP. However, there is still inconsistent evidence as to which psychological interventions are most effective to treat FAB among people with CBP. [ABSTRACT FROM AUTHOR]

Approximately 1·5 billion people worldwide live with a physical, mental, sensory, or intellectual disability, about 80% of which are in low-income and middle-income countries. This Series paper provides a global overview of the prevalence, benefits, and promotion policies for physical activity for people living with disabilities (PLWD). PLWD are 16-62% less likely to meet physical activity guidelines and are at higher risk of serious health problems related to inactivity than people without disabilities. Meta-analyses have shown that physical activity has beneficial effects on cardiovascular fitness (average standardised mean difference [SMD] 0·69 [95% CI 0·31-1·01]), musculoskeletal fitness (0·59 [0·31-0·87]), cardiometabolic risk factors (0·39 [0·04-0·75]), and brain and mental health outcomes (0·47 [0·21-0·73]). These meta-analyses also show that health benefits can be achieved even with less than 150 min of physical activity per week, and suggest that some physical activity is better than none. Meta-analyses of interventions to increase physical activity for PLWD have reported effect sizes ranging from SMD 0·29 (95% CI 0·17-0·41, k=10) to 1·00 (0·46-1·53, k=10). There is increasing awareness among policy makers of the needs of PLWD for full participation in physical activity. Physical activity action plans worldwide must be adequately resourced, monitored, and enforced to truly advance the fundamental rights of PLWD to fully participate in physical activity.

Objective: Approximately 25 % of Canadian children aged 4-8 years fail to meet the recommended dietary allowance (RDA) of calcium (Ca). Young children's food choices are primarily determined by their parents. No interventions have directly targeted parents as a medium through which to increase children's Ca consumption. This study compared the effectiveness of a Ca-specific intervention targeted towards parents, with generic dietary advice on the Ca consumption of children aged 4-10 years.Design: A parallel two-arm randomised controlled trial was conducted.Setting: The study was conducted across Canada. Both conditions received information on the RDA of Ca and an index of intake requirements. Material sent to the intervention condition included behavioural strategies to increase dietary Ca consumption, information on the benefits of dietary Ca intake and messages addressing perceived barriers to the consumption of Ca-rich foods.Participants: A total of 239 parents (93 % mothers) of children aged 4-10 years who consumed less than the RDA of Ca were randomly assigned in a 1:1 allocation ratio.Results: There was a significant increase in total Ca intake and Ca from dairy for children at weeks 8, 34 and 52 (P ≤ 0·001) in both conditions. Parental Ca intake and amount spent on dairy products did not significantly increase following the intervention.Conclusions: Provision of daily Ca requirements with regular reminders could impact parents' delivery of Ca-rich foods to their children. This finding is important for public health messaging as it suggests that parents are a potent medium through which to promote Ca intake in children. [ABSTRACT FROM AUTHOR]

Sport and exercise participation are associated with small, albeit positive changes in subjective well-being (SWB). Recent theorizing has emphasized the importance of distinguishing between performance aspects (i.e., frequency, intensity, time engaged) and the experiential aspects of sport and exercise participation among people with disabilities. This study assessed the relative contributions of time spent participating in sport and exercise (a performance measure) versus measures of participation experiences, in explaining variance in SWB. Participants were 535 adults with physical disabilities, recruited through a nation-wide survey, who participated in sport (n = 271; 62% male; 44 ± 14 years) or exercise (n = 264; 42% male; 57 ± 14 years). They completed measures of minutes/week of sport or exercise participation, experiential aspects of participation, and SWB (overall life satisfaction, satisfaction with physical, psychological and social life-domains, and positive/negative affect). Hierarchical multiple regression analyses showed minutes/week of sport did not explain significant variance in any SWB measure, but sport participation experiences explained significant variance (9.2%–20.9%) in all SWB measures (p < 0.05). Similarly, minutes/week of exercise explained significant variance only in physical life-domain satisfaction (ΔR2 = 2.6%, p = 0.026), but exercise participation experiences explained significant variance (4.8%–10.7%) in all SWB measures (p < 0.05). Experiences of belonging and mastery were particularly strong, consistent predictors across SWB outcomes. These results suggest participation experiences better explain relationships between sport and exercise participation and SWB than time spent performing sport and exercise. Findings have implications for designing future studies to test the effects of sport and exercise on SWB, and developing theories and interventions to explain and maximize the use of sport and exercise to improve SWB in adults with disabilities. • Sport/exercise participation is modestly related to subjective well-being (SWB). • This study distinguished participation time from participation experiences. • Experiences explained more variance in SWB than time spent on sport/exercise. • Belonging and mastery experiences were strong, consistent predictors of SWB. • Results have implications for theory and intervention development.

Background: Precarious work is an increasingly common characteristic of industrialized labor markets that can widen health inequities, especially among disadvantaged workforce segments. Study objectives are to compare precarious employment in workers with and without disabilities, and to examine the modifying effect of disability in the relationships between age, job tenure and precarious work.Methods: Employed Canadians with (n = 901) and without disabilities (n = 901) were surveyed on exposure to precarious working conditions. Information on age and job tenure were collected from respondents along with sociodemographic, health and work context details. Multivariable logistic models examined the association between disability and precarious work. Also, multigroup probit models examined precarious work for young (18-35 yrs), middle-aged (36-50 yrs) and older adults (> 50 yrs) and job tenure and was stratified by participants with and without disabilities.Results: Almost equal proportions of young, middle-aged and older participants were recruited. Mean job tenure of participants was 9.5 years (SD = 9.0). Close to one-third of participants reported working precariously. At the multivariable level, a disability was not associated with working precariously. However, multigroup modelling indicated that disability was a significant effect-modifier. Older adults with a disability had a 1.88 times greater odds of reporting precarious work when compared to young adults (OR = 1.88, 95%CI 1.19, 2.98). When reporting a disability, longer job tenure was related to a 0.95 times lower odds of precarious work (OR = 0.95 95%CI 0.93, 0.98). The relationship between age and job tenure was not significant for those not reporting a disability.Discussion: Precarious work has the potential to affect workers with and without disabilities. For those with a disability, being an older adult and/or a new worker can contribute to a greater likelihood of being employed precariously. Policies and programs can be recommended to address precarious working conditions and related health inequities for people with disabilities based on life and career phase. [ABSTRACT FROM AUTHOR]

The purpose of this study was to examine the effects of depleted self-control strength on skill-based sports task performance. Sixty-two participants completed the following: a baseline dart-tossing task (20 tosses), with measures of accuracy, reaction time, and myoelectrical activity of the arms taken throughout; a self-control depletion (experimental) or a nondepletion (control) manipulation; and a second round of dart tossing. As hypothesized, participants in the experimental condition had poorer mean accuracy at Round 2 than control condition participants, and a significant decline in accuracy from Round 1 to Round 2. Experimental condition participants also demonstrated poorer consistency in accuracy compared with control condition participants at Round 2 and a significant deterioration in consistency from Round 1 to Round 2. In addition, consistency in reaction time improved significantly for the control group but not for the experimental group. The results of this study provide evidence that ego depletion effects occur in the performance of a skill-based sports task. [ABSTRACT FROM AUTHOR]

This experiment examined the effects of a possible selves intervention on selfregulatory efficacy and exercise behavior among 19 men and 61 women (M age = 21.43 years, SD = 3.28) who reported exercising fewer than 3 times per week. Participants were randomly assigned to a control condition, a hoped-for possible selves intervention condition, or a feared possible selves intervention condition. The hoped-for and feared possible selves interventions required participants to imagine themselves in the future as either healthy, regular exercisers or as unhealthy, inactive individuals, respectively. Participants in the control condition completed a quiz about physical activity. Measures of self-regulatory efficacy (scheduling, planning, goal setting, and barrier self-efficacy) were taken immediately before and after the intervention. Participants who received either possible selves intervention reported greater exercise behavior 4 weeks and 8 weeks postintervention than participants in the control group. Planning self-efficacy partially mediated the effects of the possible selves intervention on exercise behavior over the first 4 weeks of the study. These findings highlight the effectiveness of possible selves interventions for increasing exercise behavior and the role of self-regulatory processes for explaining such effects.

The purpose of the present experiment was to examine whether the use of self-handicapping strategies influences participants' anxiety levels before athletic performance. Seventy-one competitive basketball players participated in the study. A repeated measures design was used, such that state cognitive and somatic anxiety intensity and direction were measured before and after participants were given the opportunity to self-handicap. Overall, participants reported their cognitive anxiety to be more facilitating after they had the opportunity to self-handicap. Thus, participants who were given the opportunity to self-handicap (i.e., use claimed and behavioral self-handicaps), reported greater increases in perceptions of cognitive anxiety as facilitating their performance. This study shows the importance of looking at anxiety direction, and not just anxiety intensity, when examining self-handicapping's effects on anxiety. Implications for sport psychologists are proposed. [ABSTRACT FROM AUTHOR]

Using the theory of planned behavior as a theoretical framework, the present study examined psychosocial predictors of exercise intentions and behavior among 124 men and women with spinal cord injury. Theory of planned behavior constructs were measured using an exercise-specific questionnaire for individuals with spinal cord injury. Exercise behavior was assessed using an adapted version of the Godin Leisure Time Exercise Questionnaire. Regression analyses indicated that the theory of planned behavior had limited utility in this population. Among individuals with tetrapelgia, perceived behavioral control was the only determinant of exercise intentions and behavior. Among people with paraplegia, none of the theory of planned behavior constructs predicted exercise intentions or behavior. These results have methodological and practical implications for future research and exercise interventions, respectively. [ABSTRACT FROM AUTHOR]

Purpose: To compare psychological responses to, and preferences for, moderate-intensity continuous training (MICT), high-intensity interval training (HIIT), and sprint interval training (SIT) among inactive adults; and to investigate the relationships between affect, enjoyment, exercise preferences, and subsequent exercise behavior over a 4-wk follow-up period. Methods: Thirty inactive men and women (21.23 ± 3.81 yr), inexperienced with HIIT or SIT, completed three trials of cycle ergometer exercise in random order on separate days: MICT (45 min continuous; approximately 70% to 75% of HR maximum (HRmax)); HIIT (10 × 1 min bouts at approximately 85% to 90% HRmax with 1-min recovery periods); and SIT (3 × 20-s “all-out” sprints with 2-min recovery periods). Perceived exertion (RPE), affect, and arousal were measured throughout the trials and enjoyment was measured postexercise. Participants rank-ordered the protocols (1–3) according to preference and logged their exercise over a 4-wk follow-up. Results: Despite elevated HR, RPE, and arousal during work periods (P ’s < 0.05), and negative affect during HIIT and SIT, enjoyment and preferences for MICT, HIIT, and SIT were similar (P’ s > 0.05). In-task affect was predictive of postexercise enjoyment for each type of exercise (r’ s = 0.32 to 0.47; P’ s < 0.05). In-task affect and postexercise enjoyment predicted preferences for HIIT and SIT (r s’s = −0.34 to −0.61; P’ s < 0.05), but not for MICT (P’ s > 0.05), respectively. Over the follow-up, participants completed more MICT (M = 6.11 ± 4.12) than SIT sessions (M = 1.39 ± 1.85; P < 0.01, d = 1.34). Although participants tended to complete more sessions of MICT than HIIT (M = 3.54 ± 4.23; P = 0.16, d = 0.56), and more sessions of HIIT than SIT (P = 0.07, d = 0.60), differences were not significant. In-task affect predicted the number of sessions of MICT (r = 0.40; P < 0.05), but not HIIT or SIT (P’ s > 0.05). Conclusions: This study provides new evidence that a single session of HIIT and SIT can be as enjoyable and preferable as MICT among inactive individuals and that there may be differences in the exercise affect–behavior relationship between interval and continuous exercise.

The objective of this review was to summarize the literature supporting narrative interventions that target health-promoting behaviours. Eligible articles were English-language peer-reviewed studies that quantitatively reported the results of a narrative intervention targeting health-promoting behaviours or theoretical determinants of behaviour. Five public health and psychology databases were searched. A total of 52 studies met inclusion criteria. In all, 14 studies found positive changes in health-promoting behaviours after exposure to a narrative intervention. The results for the changes in theoretical determinants were mixed. While narrative appears to be a promising intervention strategy, more research is needed to determine how and when to use these interventions. [ABSTRACT FROM AUTHOR]

Objectives Among samples of people with physical disabilities, the effects of physical activity (PA) interventions and the factors that influence intervention success are unknown. The purpose of this meta-analysis was to i) evaluate the overall effect of interventions on PA behaviour and ii) examine the influence of intervention characteristics, theory, and behaviour change techniques (BCTs) on PA intervention effects in persons with physical disability. Design Meta-analysis. Method Medline, Embase, PsychINFO, and AMED databases were searched for randomized controlled trials that evaluated the effects of a PA intervention in people with physical disability. Data were extracted regarding study and intervention characteristics and use of theory. Intervention descriptions were coded using the BCT Taxonomy version 1. Results A total of 24 articles met the inclusion criteria. Overall, interventions had a small to medium-sized effect on PA behaviour ( g  = 0.35, k = 22, 95% CI [0.21, 0.48]). Interventions that used theory ( g  = 0.53, k  = 12, 95% CI [0.38, 0.68]) had larger effects than interventions that did not, p  < 0.001. Interventions that included self-monitoring of behaviour produced larger effects ( g  = 0.45 k  = 12, 95% CI [0.28, 0.63], p  = .04) and interventions with monitoring of behaviour by others without feedback produced smaller effects ( g  = 0.05, k  = 3, 95% CI [-0.22, 0.32], p  = .02) than studies without these BCTs. Conclusion Interventions to increase PA behaviour in people with physical disability are effective, especially when theory is used to guide their development. Research is needed to examine a wider range of BCTs and the moderating effects of intervention characteristics on PA behaviour. [ABSTRACT FROM AUTHOR]

This study investigated the impact of listening to music during exercise on perceived enjoyment, attitudes and intentions towards sprint interval training (SIT). Twenty men (24.8 ± 4.5 years) and women (20.1 ± 2.6 years) unfamiliar with SIT exercise completed two acute sessions of SIT, one with and one without music. Perceived enjoyment, attitudes and intentions towards SIT were measured post-exercise for each condition. Attitudes and intentions to engage in SIT were also measured at baseline and follow-up. Post-exercise attitudes mediated the effects of enjoyment on intentions in the music condition (95% confidence interval [CI]: [0.01, 0.07],κ2 = 0.36) and in the no music condition (95% CI: [0.01, 0.08],κ2 = 0.37). Attitudes towards SIT were significantly more positive following the music than no music condition (P = 0.004), while intentions towards SIT were not (P = 0.29). Further, attitudes and intentions towards SIT did not change from baseline to follow-up (Ps > 0.05). These findings revealed that participants had relatively positive attitudes and intentions towards SIT, which did not become more negative despite experiencing intense SIT protocols. This study highlights the importance of acute affective responses to SIT exercise for influencing one’s attitudes and intentions towards participating in SIT exercise. Such factors could ultimately play a key role in determining whether an individual engages in SIT exercise in the long term. [ABSTRACT FROM AUTHOR]

Physical activity (PA) counselling research has mainly focused on identifying which behaviour change techniques (BCTs) are delivered by a counsellor. Less is known about how BCTs are received by clients. State Space Grids (SSGs) is a dynamic system method that can be used to study counsellor-client interactions by examining frequencies, durations and sequences of BCT delivery and receipt. In this methods paper, we show how SSG methods can be pragmatically used to characterize counsellor-client interactions during a PA behavioural support intervention for adults with disabilities. Methods were demonstrated through a secondary analysis of data from adults with spinal cord injury (age: 45.79 ± 13.63; females: n = 5; males: n = 9) who received PA counselling. Transcripts of 30 audio-recorded counselling sessions (total duration: ∼8.3 h) were double-coded for BCT delivery and receipt statements using a reliable coding method (>84% agreement) and analyzed in two different ways using SSGs methods. Applying the SSG analyses to our data demonstrated that frequencies, durations, and sequences of BCT delivery and receipt varied largely within and between dyads. Across all sessions, the counsellor and client spent on average 32–34% of their time on talking about BCTs related to goals and planning, ∼29% of their time talking about other BCTs (e.g., self-belief, support strategies), and the remaining 27–29% of their time talking about other topics (not BCT-specific). This paper showed how dynamic system methods can be pragmatically used to characterize counsellor-client interactions and illustrate the variability of how BCTs are delivered by a counsellor and received by clients in a PA behavioural support intervention. We demonstrated that SSGs methods can facilitate the examination of frequencies, durations and sequences of BCT delivery and receipt can help advance our understanding of PA behavioural support for adults with and without disabilities. • First using State Space Grids in exercise counselling in clients with disabilities. • Demonstration of how behaviour change techniques are delivered and received. • Show how State Space Grids may advance science and practice of exercise counselling.

The primary purpose of this study was to propose and test a mediation model of changes in physical self-efficacy, physical self-perceptions, and affect as mediators by which a single bout of exercise improves state body image. A secondary purpose was to identify how long improvements in state body image are sustained post-exercise. Sixty university-aged women (19.57 ± 1.37 y) with pre-existing body image concerns, and who exercised regularly, were randomized to perform 30 min of moderate-to-vigorous intensity exercise or quiet reading. State body image, physical self-efficacy, physical self-perceptions and affect were assessed. Mediational analyses revealed self-perceptions of body fatness (95% CI [0.03, 0.44], κ 2 = 0.13, ab ps = 0.20) and strength (95% CI [0.15, 0.60], κ 2 = 0.23, ab ps = 0.33) mediated improvements in state body image which were sustained at least 20 min post-exercise. These results contribute to the development of a model explaining the effects of exercise on body image and practical recommendations for the use of exercise to improve body image.

Health information can be presented in different formats, such as a statistically-based or a story-based (e.g. narrative) format; however, there is no consensus on the ideal way to present screening information. This systematic review summarizes the literature pertaining to narrative interventions’ efficacy at changing screening behaviour and its determinants. Five psychology and public health databases were searched; 19 studies, 18 focused on cancer and 1 on sexual health, met eligibility criteria. There is consistent evidence supporting the efficacy of narratives, but mixed evidence supporting an advantage for narratives over statistical interventions for screening behaviour and its determinants. Further investigation is warranted. [ABSTRACT FROM AUTHOR]

Background: The impending public health impact of Alzheimer's disease is tremendous. Physical activity is a promising intervention for preventing and managing Alzheimer's disease. However, there is a lack of evidence-based public health messaging to support this position. This paper describes the application of the Appraisal of Guidelines Research and Evaluation II (AGREE-II) principles to formulate an evidence-based message to promote physical activity for the purposes of preventing and managing Alzheimer's disease.Methods: A messaging statement was developed using the AGREE-II instrument as guidance. Methods included (a) conducting a systematic review of reviews summarizing research on physical activity to prevent and manage Alzheimer's disease, and (b) engaging stakeholders to deliberate the evidence and formulate the messaging statement.Results: The evidence base consisted of seven systematic reviews focused on Alzheimer's disease prevention and 20 reviews focused on symptom management. Virtually all of the reviews of symptom management conflated patients with Alzheimer's disease and patients with other dementias, and this limitation was reflected in the second part of the messaging statement. After deliberating the evidence base, an expert panel achieved consensus on the following statement: "Regular participation in physical activity is associated with a reduced risk of developing Alzheimer's disease. Among older adults with Alzheimer's disease and other dementias, regular physical activity can improve performance of activities of daily living and mobility, and may improve general cognition and balance." The statement was rated favourably by a sample of older adults and physicians who treat Alzheimer's disease patients in terms of its appropriateness, utility, and clarity.Conclusion: Public health and other organizations that promote physical activity, health and well-being to older adults are encouraged to use the evidence-based statement in their programs and resources. Researchers, clinicians, people with Alzheimer's disease and caregivers are encouraged to adopt the messaging statement and the recommendations in the companion informational resource.

Purpose: To identify psychosocial factors which explain lower levels of leisure time physical activity (LTPA) in persons with spinal cord injury (SCI) who are ambulatory relative to those who use manual wheelchairs.Method: For the quantitative study component, 347 adults with SCI (78% male;Mage = 47.7) completed baseline measures of LTPA attitudes, subjective norms, perceived behavioural control and intentions. Six months later, LTPA was assessed. The qualitative component involved semi-structured interviews with six ambulant adults with SCI (five male,Mage = 52.8) addressing LTPA experiences with an emphasis on barriers and facilitators.Results: Ambulatory individuals had poorer attitudes towards LTPA than chair users (p = 0.004). Their attitudes had significant indirect effects on LTPA, through intentions. Perceived behavioural control was a significant negative predictor of LTPA. Qualitative analysis revealed three themes: an underestimated disability, low wheelchair skill self-efficacy and experiencing chronic pain.Conclusions: Poorer attitudes towards LTPA may partially explain why ambulatory individuals are less active. The qualitative and quantitative data suggest ambulators are an often-overlooked subgroup in need of targeted resources to enhance their attitudes, wheelchair skill self-efficacy and awareness of LTPA opportunities.Implications for RehabilitationRehabilitation practitioners must be sensitive to the unique needs of spinal cord injured individuals who are ambulatory, and tailor physical activity promotional strategies to suit the needs of this distinct group.Lack of wheelchair skills is a participation barrier for ambulators; ambulators should be introduced to activities that do not require wheelchair use, such as swimming, hand-cycling and adapted forms of circuit training.Strategies that encourage wheelchair skill development in non-wheelchair using ambulators, may increase physical activity opportunities for this segment of the spinal injured population.

Dozens of published papers cite factors related to leisure-time physical activity (LTPA) participation among people with physical disabilities. Unfortunately, there has been little effort to synthesise this literature in a manner that is accessible and useful to the sectors (e.g., health care, recreation) responsible for LTPA promotion in disability populations. In this systematic review, over 200 factors were extracted from 22 review articles addressing barriers and facilitators to LTPA in children and adults with physical disabilities. Factors were grouped according to common themes, classified into five levels of a social ecological model, and coded according to whether they could be affected by the health-care and/or recreation sectors. Findings are discussed with regard to key factors to target in LTPA-enhancing interventions, relevant theories and models in which to frame interventions, the levels at which the interventions can be implemented, and intervention priorities. The synthesis provides a blueprint and a catalyst for researchers and practitioners to shift focus from conducting studies that merely describe LTPA barriers and facilitators, to developing and delivering strategies to increase LTPA among persons with physical disabilities.

Purpose: The purposes of the current study were to (1) describe the restructuring and dissemination of a Canada-wide intervention curriculum designed to enhance health care professionals' prescription of physical activity to patients with physical disabilities, and (2) examine interventionists' social cognitions for, and their acceptance and adoption of, the new curriculum. Methods: A participatory curriculum development process was utilized, resulting in a theory- and evidence-based curriculum. Interventionists ( N = 28) were trained in curriculum delivery and most ( n = 22) completed measures of Theory of Planned Behavior (TPB) constructs assessing their cognitions for delivering the new curriculum at pre- and post-training and at 6-month follow-up. Interventionists also completed a Diffusion of Innovations (DOI) measure assessing their opinion of whether the new curriculum met characteristics that would facilitate its adoption and use. Results: Interventionists reported strong TPB cognitions for curriculum use before training. Significant increases emerged for some TPB constructs (ps ≤ 0.025) from pre- to post-training, and significant decreases were seen in some TPB constructs (ps ≤ 0.024) between post-training and 6-month follow-up. The interventionists rated the new curriculum as high on all the DOI characteristics. Conclusion: The theory-driven, participatory development process facilitated interventionists' social cognitions towards and adoption of the new curriculum. Positive increases in TPB cognitions from pre- to post-training were not maintained at follow-up. Further research is needed to determine if these changes in cognitions are indicative of a curriculum 'reinvention' process that facilitates long-term curriculum use. Understanding curriculum adoption and implementation is a crucial step to determining the potential population impact of the intervention. [ABSTRACT FROM AUTHOR]

Background The RE-AIM (Reach, Effectiveness, Adoption, Implementation, and Maintenance) framework is a reliable tool for the translation of research to practice. This framework has been widely applied to assess the impact of individual interventions. However, RE-AIM has rarely been used to evaluate implementation interventions, especially from multi-sector partnerships. The primary purpose of this paper is to operationalize the RE-AIM approach to evaluate large, multi-sector partnerships. SCI Action Canada, a community-university partnership aimed to promote physical activity among adults with spinal cord injury, is used as an example. A secondary purpose is to provide initial data from SCI Action Canada by using this conceptualization of RE-AIM. Methods Each RE-AIM element is operationalized for multi-sector partnerships. Specific to SCI Action Canada, seven reach calculations, four adoption rates, four effectiveness outcomes, one implementation, one organizational maintenance, and two individual maintenance outcomes are defined. The specific numerators based on SCI Action Canada activities are also listed for each of these calculations. Results The results are derived from SCI Action Canada activities. SCI Action Canada's reach ranged from 3% (end-user direct national reach) to 37% (total regional reach). Adoption rates were 15% (provincial level adoption) to 76% (regional level adoption). Implementation and organizational maintenance rates were 92% and 100%, respectively. Conclusions We have operationalized the RE-AIM framework for larger multi-sectoral partnerships and demonstrated its applicability to such partnerships with SCI Action Canada. Future partnerships could use RE-AIM to assess their public health impact. [ABSTRACT FROM AUTHOR]

Background Healthcare professionals (HCPs) are vital conduits of leisure-time physical activity (LTPA) information; however, few discuss LTPA with their patients with disabilities. 'Changing Minds, Changing Lives' (CMCL) is a nationwide, theory- and evidence-based seminar aimed at increasing LTPA-discussion among HCPs by enhancing their attitudes, subjective norms, perceived behavioural control (PBC), and intentions. The purposes of the current study were to: examine the effectiveness and short- and long-term maintenance of a CMCL seminar on HCPs' social cognitions to discuss LTPA; and explore key implementation variables that predict changes in HCPs' social cognitions. Methods Prior-to, as well as immediately, one, and six months following a CMCL seminar, 97 HCPs (Mage ± SD = 36.23 ± 10.42; 69.0% female; 97.9% Caucasian; 38.1% rehabilitation therapists; years in profession = 11.56 ± 9.94) from five Canadian provinces completed questionnaires that assessed the Theory of Planned Behaviour constructs with regard to discussing LTPA with their patients with a physical disability. Key presenter characteristics and intervention delivery components were extracted from presenter demographic questionnaires and seminar checklists, respectively. Separate repeated-measures ANOVAs and post-hoc t-tests evaluated changes in HCPs' social cognitions. Hierarchical multiple regressions were conducted to predict intentions and to understand which implementation variables may help explain significant changes in social cognitions. Results Significant increases in HCPs' social cognitions for discussing LTPA were reported from pre- to post-seminar (ps <0.002); however, increases were not maintained at follow-up. PBC emerged as the strongest predictor of participants' post-CMCL intentions (β = 0.45, p <0.001). Although several implementation characteristics were related to changes in perceptions, the number of seminars the presenter delivered was the only significant negative predictor of post-seminar PBC (β = -0.18, p <0.05). Conclusions Future iterations of the CMCL intervention should include additional strategies to sustain improvements in HCPs' social cognitions over time. Future CMCL evaluations should measure additional implementation variables so that the key ingredients for 'Changing Minds' can continue to be investigated. [ABSTRACT FROM AUTHOR]

Objective: This article is the first in a three-part series focused on designing theory-based interventions to increase leisure time physical activity (LTPA) in persons with spinal cord injury (SCI). The purpose of this first study was to compare social cognitions for LTPA between people classified as LTPA actors, intenders, and nonintenders, as per Schwarzer's Health Action Process Approach (HAPA) model. Method: Participants were 238 men and women living with a SCI (M age = 44.14, SD = 12.74; 44.5% paraplegic) who were subsequently classified as LTPA actors (n = 105), intenders (n = 73), or nonintenders (n = 60). Participants completed a questionnaire that assessed the following HAPA constructs: LTPA outcome expectancies, self-efficacy, intentions, planning, and action control. Results: A MANCOVA revealed significant between-groups differences for all variables (ps < .001). For all of the measures, actors scored significantly higher than intenders who, in turn, scored significantly higher than nonintenders. Conclusion/Implications: It is both theoretically and practically important to distinguish between LTPA nonintenders, intenders, and actors when developing LTPA-enhancing interventions for people with SCI. These distinctions inform the design and testing of the interventions reported in the two accompanying articles. [ABSTRACT FROM AUTHOR]

Parents of children and youth with disabilities (CYD) have expressed unique physical activity (PA) information needs. Community-based organizations (CBOs) require assistance to meet these needs. Guided by the Appraisal of Guidelines, Research and Evaluation II, this project established evidence-informed recommendations for developing PA information targeting families of CYD. This process involved a systematic scoping review to inform draft recommendations (k = 23), which were revised via a consensus meeting with researchers, knowledge users from CBOs, and families of CYD. Broader consultation with CBO knowledge users informed the final recommendations (k = 5) that fit within the following categories: (a) language and definitions, (b) program information, (c) benefits of PA, (d) barriers to PA, and (e) PA ideas and self-regulation tools. CBOs are encouraged to consider these recommendations when developing PA information for families of CYD. Future research will focus on the development of knowledge products to disseminate the recommendations to CBOs and support implementation. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this study was to conduct a curriculum scan of Canadian undergraduate university programs to determine the relative emphasis placed on the activity and exercise after spinal cord injury (SCI), in the context of physical disability studies. Method: Eighty-three Canadian Universities were evaluated for courses discussing: (i) general information about SCI, (ii) physical activity and exercise after SCI, (iii) general information about other physical disabilities and (iv) physical activity and exercise for such disabilities. Online course calendars (2009) were scanned, and their accuracy was verified by instructors or administrative assistants. Results: The curriculum scan revealed 113 courses that discuss physical disability. Seventy-four of these courses cover information regarding SCI, 47 of which include content relating to activity and exercise. In comparison, 104 courses discuss other physical disabilities, 76 of which cover material related to activity and exercise. Further, the 47 courses that cover activity and exercise after SCI are only offered in 22 Canadian Universities, and only 31 are mandatory for a degree. Conclusions: A substantial number of future healthcare professionals lack exposure to material regarding activity and exercise after SCI during their undergraduate education. This curricular oversight likely contributes to ineffective exercise strategies and the relative inactivity of the SCI population. [ABSTRACT FROM AUTHOR]

Abstract: Objectives: To determine whether a home advantage or disadvantage is evident in loss and win-imminent situations within National Hockey League (NHL) shootouts. Design: Archival. Method: Shooting percentages were analyzed from the 2006–2011 NHL seasons and shots were classified as: loss-imminent (when a miss results in a loss for the shooter''s team); win-imminent (when a goal results in a win for the shooter''s team); or non-outcome-imminent (when a miss or goal does not immediately determine the outcome of the game). Results: A home advantage was evident in loss-imminent situations when a team needed to score to avoid a loss. By contrast, a home disadvantage was evident in win-imminent situations when a team was shooting to win. Conclusion: The home (dis)advantage varies across different outcome-imminent situations. Comparing home and away teams'' success in specific situations within a sporting match may be a valuable way of assessing the home (dis)advantage in sports. [Copyright &y& Elsevier]

Purpose: The purpose of this study was to determine whether self-efficacy can account for the relationship between wheelchair skills and leisure-time physical activity (LTPA) in people with spinal cord injury (SCI). Method: Fifty-four manual wheelchair users with SCI participated in this cross-sectional study. Participants completed a wheelchair skills test, and self-report measures of wheelchair-use self-efficacy, LTPA barrier self-efficacy, and LTPA. It was hypothesized that a positive wheelchair skills-LTPA relationship would be mediated by wheelchair-use self-efficacy and LTPA barrier self-efficacy. Results: Using linear regression models, a positive association between wheelchair skills and LTPA was established (β = 0.27, p < 0.05). LTPA barrier self-efficacy was a significant partial mediator, explaining 47.7% of the variance of the total relationship between skills and LTPA. Wheelchair-use self-efficacy was not a significant mediator of the wheelchair skills-LTPA relationship. Conclusions: Wheelchair skills play a modest role in LTPA participation and may facilitate LTPA, if skills help people feel more self-efficacious in their abilities to overcome LTPA barriers. The results have implications for understanding and improving LTPA participation. Improvements in wheelchair skills may facilitate LTPA, if people are taught the skills needed to increase their self-efficacy to overcome barriers to LTPA participation. [ABSTRACT FROM AUTHOR]

Background: Little theory-based research has focused on understanding and increasing physical activity among people with physical disabilities. Testing a social cognitive theory-based model of determinants is important for identifying variables to target in physical activity-enhancing interventions. Purpose: The aim of this study is to examine Social Cognitive Theory variables as predictors of physical activity among people living with spinal cord injury. Methods: Structural equation modeling was used to test a model of Social Cognitive Theory predictors of physical activity ( n = 160). Results: The model explained 39% of the variance in physical activity. Self-regulation was the only significant, direct predictor. Self-regulatory efficacy and outcome expectations had indirect effects, mediated by self-regulation. Conclusion: Social Cognitive Theory is useful for predicting physical activity in people with spinal cord injury. Self-regulation is the most potent Social Cognitive Theory predictor of physical activity in people with spinal cord injury. Self-regulation and its determinants should be targeted in physical activity-enhancing interventions. [ABSTRACT FROM AUTHOR]

Background: Adequate calcium consumption during early adulthood can help prevent osteoporosis in women. Purpose: The effects of gain-framed, targeted messaging on calcium intake were examined over 12 months. Methods: Young women (18-19 years) not consuming sufficient calcium were randomly assigned to receive standard care materials (control) or gain-framed, targeted materials (experimental). Health belief model (HBM) constructs, calcium intake and markers of bone formation, resorption and bone mineral density were assessed at various time points throughout the year. Results: Calcium intake increased significantly more in the experimental versus the control condition (p < 0.01). Self-efficacy was the only HBM construct to improve significantly more in the experimental condition versus control (p = 0.05). The HBM did not mediate changes in calcium intake. Measures of bone health did not differ between conditions by the end of this nonpharmacological intervention (p's > 0.05). Conclusions: It is possible to increase young women's calcium consumption through gain-framed, targeted messages. [ABSTRACT FROM AUTHOR]

To explore the perceptions of people with spinal cord injury (SCI) regarding preferred messengers and methods for obtaining physical activity (PA) information. Design: Using a phenomenological approach and interviewing techniques, five focus groups discussed PA information delivery methods and messengers. Participant: Sixteen community-dwelling adults with SCI (30.5% tetraplegia, 37.5% paraplegia; at least one-year post injury) whose PA levels ranged from sedentary to regularly active. Results: Content analyses revealed that the preferred media of r obtaining PA information were passive sources (e.g., Internet, DVDs, newsletters). The preferred messengers were peers and health service providers. There were diverse perspectives about the value and types of PA messages to share with people in the acute, rehabilitation, and postdischarge stages. Conclusions: The methods and messengers identified in this study illustrate the need for interdisciplinary engagement among various program and health care providers to work together to effectively deliver PA information to all individuals with SCI. People will be receptive to different messages, from different channels, at different times. [ABSTRACT FROM AUTHOR]

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.

The primary purpose of this study was to test the predictions of the dual-mode model using arm ergometry as the exercise modality. It was hypothesized that changes in affect during exercise would be greater in high (105% VT)- and low (80% VT)-intensity exercise conditions than in a control condition, while differences in affect would be observed between exercise conditions. Study participants were 24 physically active men. A within-subjects design was used. Affect was measured using the Activation–Deactivation Adjective Check List and the State Anxiety Inventory. Cognitive (i.e. self-efficacy and enjoyment) and physiological (i.e. heart rate, pain and perceived exertion) mediators of the exercise–affect relationship were also examined. Results showed that during exercise, changes in affect were greater in the exercise conditions than the control condition, and affective valence in the exercise conditions declined relative to the control condition. In partial support of the dual-mode model, self-efficacy mediated the relationship between below-VT exercise and affect, whereas pain mediated the relationship between above-VT exercise and affect. These findings highlight the importance of exercise intensity to the affective benefits of exercise. [ABSTRACT FROM PUBLISHER]

Theory of Planned Behavior (TPB) constructs have been shown to be useful for explaining leisure-time physical activity (LTPA) in persons with spinal cord injury (SCI). However, other factors not captured by the TPB may also be important predictors of LTPA for this population. The purpose of this study is to examine the role of neighborhood perceptions within the context of the TPB for understanding LTPA in persons living with SCI. This is a cross-sectional analysis ( n = 574) using structural equation modeling involving measures of the TPB constructs, perceived neighborhood esthetics and sidewalks, and LTPA. TPB constructs explained 57% of the variance in intentions and 12% of the variance in behavior. Inclusion of the neighborhood variables to the model resulted in an additional 1% of the variance explained in intentions, with esthetics exhibiting significant positive relationships with the TPB variables. Integrating perceived neighborhood esthetics into the TPB framework provides additional understanding of LTPA intentions in persons living with SCI. [ABSTRACT FROM AUTHOR]

The combination of low physical activity rates and increased cardiovascular deaths indicate the overwhelming need for behaviour change interventions that can effectively promote physical activity among sedentary women. This 11-week randomised controlled trial examined the effects of an implementation intentions intervention on sedentary women's walking behaviour. Seventy-five women (M age = 48.17) were randomly assigned to either a control group where they were required to self-monitor their daily pedometer-determined step count or to an experimental group where they were asked to form specific walking plans (i.e. implementation intentions) every 6 weeks and to self-monitor their daily pedometer-determined step count. Measures of exercise intentions, perceived behavioural control, scheduling and barrier self-efficacy were administered at baseline, week 6 and week 11. Analyses indicated higher step counts over the first 6 weeks for women in the experimental condition (p < 0.02). Furthermore, higher self-efficacy to schedule (p < 0.01) and overcome walking barriers (p < 0.03), as well as higher perceptions of behavioural control (p < 0.02) were found at week 11 for women in the experimental versus control condition. However, none of the control beliefs were found to mediate the effects of the intervention on the women's walking behaviour. Furthermore, the intervention did not have any effect on the strength of the goal intention-behaviour relationship. The findings suggest implementation intentions are an effective strategy for initiating leisure-time walking within sedentary women. [ABSTRACT FROM AUTHOR]

The purpose of the present study was to examine the effects of a self-regulatory strength depletion manipulation on performance of a physical endurance (isometric handgrip) task. In addition, the effect of depletion on EMG activity in the working forearm muscles during the endurance task was explored. Sedentary undergraduates ( N=49) were randomly assigned to either a cognitive depletion condition (modified Stroop task) or a control (color word) group and completed two maximal isometric exercise endurance trials separated by the cognitive task. Participants in the depletion group showed significant ( p<.05) degradations in performance and exhibited higher EMG activation on the second endurance trial ( p<.05) compared to controls. Results are consistent with the limited strength model of self-regulation and are interpreted in light of the central fatigue hypothesis. [ABSTRACT FROM AUTHOR]

The unique and interactive effects of mirrored exercise environments and the presence of co-exercisers on sedentary women's exercise-induced feeling states (FS) were examined. Participants (n = 92; mean age = 20.2) performed 20 min of moderate intensity exercise in one of four environments: (a) alone/mirrored, (b) not alone/mirrored, (c) alone/unmirrored, or (d) not alone/unmirrored. FS were measured pre-, mid-, and 5 min post-exercise. Self-consciousness, perceived social evaluation and social comparisons were also assessed post-exercise. Multilevel modeling procedures indicated that women in the not alone/mirrored environment experienced smaller increases in post-exercise revitalization than the other conditions (p < 0.05), and were the only condition to experience increased physical exhaustion (p < 0.05). Women in the not alone/mirrored condition also reported greater self-consciousness and more social comparisons than those in alone/mirrored condition (ps < 0.01). Findings are consistent with Objective Self-Awareness Theory, and suggest that mirrored, group exercise environments are not conducive to psychological well-being among women unaccustomed to exercise.

Objective: To evaluate the efficacy of an 8-week implementation intention intervention for promoting physical activity among individuals with spinal cord injury. Study Design: Randomized clinical trial. Method: Participants were randomly assigned to an implementation intention intervention (n = 26) or control (n = 28) condition and were asked to engage in 30 min of moderate to heavy intensity physical activity 3 times per week. Results: Participants who formed implementation intentions followed through with their physical activity intentions, engaging in more physical activity than participants in the control condition. Participants in the intervention condition also experienced sustained motivation and greater confidence to schedule physical activity compared with participants in the control condition. Implications: These findings suggest a role for implementation intentions in health promotion programs for people with spinal cord injury. [ABSTRACT FROM AUTHOR]

This experiment examined whether information about a woman's body weight moderates the effects of information about her exercise habits on ratings of her personality and physical appearance. In a 3 (target's exercise status) x 3 (target's body weight) factorial design, participants (N = 164) read a description of a young woman described as an exerciser, nonexerciser, or control and who was underweight, average weight, or overweight. They then rated her on various personality and physical-attractiveness dimensions. For the personality ratings, the nonexerciser was rated less favorably than were exerciser and control targets, regardless of her body weight. For the appearance ratings, body weight moderated the effects of exercise habit information such that being underweight countered negative stereotypes associated with being a nonexerciser and being an exerciser countered negative stereotypes associated with being overweight.

The purpose of this study was to investigate the exercise stereotype phenomenon and the moderating effects of exerciser impression motivation and construction on this stereotype in a sample of 176 female and 96 male Swedish university students. The participants read a description of one of the following female targets: a typical exerciser, an active living target, an excessive exerciser, a non-exerciser, or a control target, and then rated these targets on 12 personality (e.g., lazy–hard worker, dependent–independent) and 8 physical (e.g., scrawny–muscular, sick–healthy) dimensions. They also completed the Self Presentation in Exercise Questionnaire, measuring motivation to self-present as an exerciser and the propensity to construct the image of an exerciser. MANCOVAs revealed a significant main effect for both personality and physical attributes ( p < 0.05). In general, the typical exerciser and active living targets received the most favorable ratings, especially on the physical attributes, whereas the excessive exerciser obtained the least positive ratings. Exerciser impression motivation moderated the exercise status/rating relationship for the physical attributes only. Differences between Swedish and North American students’ impressions of exercisers and non-exercisers are discussed. [ABSTRACT FROM AUTHOR]

Objective: To examine the utility of the theory of planned behavior (TPB) for predicting leisure time physical activity (LTPA) among individuals with spinal cord injury (SCI). Study Design: Prospective correlational design. Participants: 104 men (n = 75) and women (n = 29) with SCI. Method: Baseline telephone interview assessing attitudes, subjective norms, perceived behavioral control (PBC), and intentions for engaging in LTPA. One-week follow-up telephone interview assessing frequency of LTPA. Results: Attitudes (β = .29), subjective norms (β = .29), and PBC (β = .47) each predicted LTPA intentions. LTPA intentions (β = .45) but not PBC (β = -.05) predicted LTPA. Furthermore, intentions mediated the attitudes-LTPA, subjective norms-LTPA, and PBC-LTPA relationships. Conclusions: These findings support the tenets of the TPB and provide a foundation for developing interventions promoting LTPA in the SCI population. [ABSTRACT FROM AUTHOR]

Using the framework of the Theory of Planned Behaviour (TPB), this study examined whether the extent to which people are concerned with others' approval of them moderates the subjective norms-intentions relationship in the context of exercise. The participants were 325 undergraduate students who completed a questionnaire assessing the TPB constructs (subjective norms, attitudes, perceived behavioural control, intentions) and the Brief Fear of Negative Evaluation Scale. The results of hierarchical regression analyses indicated that subjective norms were a significant predictor of intentions to exercise only for people highly concerned with receiving disapproval from others (i.e. high fear of negative evaluation) and not for people low on this trait.

Purpose: To assess exercise as a strategy for reducing pain and improving subjective well-being (SWB) among people with spinal cord injury (SCI). Design: Randomized controlled trial. Method and Participants: Thirty-four individuals with SCI. Exercisers performed aerobic and resistance training twice weekly, whereas wait-list controls maintained their usual level of activity. Results: Analyses of covariance indicated that after 3 months, exercisers reported less pain, depression, and stress, as well as greater perceived quality of life and better physical self-concept than controls (ps < .05). Regression analyses revealed that changes in pain and stress mediated exercise-induced changes in perceived quality of life and depression. Conclusion: Changes in pain and stress may be mechanisms by which exercise improves SWB among people with SCI. [ABSTRACT FROM AUTHOR]

This study examined whether the exerciser stereotype extends to moderately and excessively active individuals, and if the rater’s self-described exercise status moderates the effect. Using a 2 (exercise status) x 5 (target type) design, 456 participants read a description of a typical exerciser, a nonexerciser, an active-living target, an excessive exerciser, or a control target and rated her on 12 personality and 8 physical dimensions. MANOVAs revealed a significant main effect for target type on both personality and physical dimensions (ps < .05). For most of the personality attributes, the exerciser and active-living target were rated more favorably than were the excessive exerciser, nonexerciser and control. For the physical attributes, the typical exerciser, active-living target and excessive exerciser were rated more highly than were the nonexerciser and control. The exercise status x target type interaction was significant for only three physical dimensions. Overall, results indicate that the exerciser stereotype exists regardless of the rater’s exercise status and can generalize to different levels of physical activity. [ABSTRACT FROM AUTHOR]

Women who exercise in front of a mirror do not experience the psychological benefits that are typically associated with exercise (Martin Ginis et al., 2003). According to objective self-awareness theory (Duval & Wicklund, 1972), gazing into a mirror enhances self-awareness. Women with a negative sense of self as an exerciser (i.e., sedentary women) who exercise in a mirrored environment may experience heightened self-awareness, which may elicit a negative affective response. Using an interference paradigm, this experiment examined self-awareness as a potential mechanism underlying the detrimental effects of mirrored environments on sedentary women's (n = 87; M age = 20.2) psychological response to exercise. Participants performed 20 min of moderate intensity exercise either in front of a mirrored or an unmirrored wall with or without a distracter (a counting task). Participants completed the Exercise-Induced Feeling Inventory (Gauvin & Rejeski, 1993) pre- and 15 min post-exercise. Self-awareness was assessed immediately pre- and post-exercise with the Private Self-Consciousness Scale (Fenigstein et al., 1975). Multilevel linear models revealed a trend for women in the mirrored condition without distraction to be more self-aware post-exercise than women in the unmirrored (p = .06) and mirrored conditions (p = .27) with distraction. Also, women in the mirrored condition without distraction tended to feel more exhausted post-exercise than women in the other conditions (ps < .27). Participants who were distracted scored the same or worse for positive engagement, revitalization, and tranquility than women who exercised in front of the mirror without distractions. An evaluation of the distracter task suggested that the monotony of the task may have affected these feeling states negatively. Nonetheless, results from this preliminary experiment provide some support for objective self-awareness theory, suggesting that exercising in mirrored environments may heighten self-awareness, which may increase negative affect. Further research using alternate distracter tasks is needed. [ABSTRACT FROM AUTHOR]
