Self-determined motivation in physical education and its links to motivation for leisure-time physical activity, physical activity, and well-being in general

The present study tested a trans-contextual model based on self-determination theory of the relations between motivation in physical education, motivation in leisure-time physical activity, physical activity, and psychological well-being. Participants were 329 Norwegian upper secondary school students (M age = 16.5 yr., SD = 0.7). Students' perceptions of autonomy-supportive teachers in physical education were expected to be positively associated with students' psychological needs satisfaction in physical education, which was expected to be positively related to autonomous motivation for physical education participation. In turn, autonomous motivation for physical education was expected to be positively associated with perceived competence and autonomous motivation for leisure-time physical activity, which both were expected to be positively associated with leisure-time physical activity and psychological well-being in general. Structural equation models and bootstrapping supported the hypotheses and the indirect links between variables. Sex differences indicate that more research is needed on how to motivate girls to be more physically active in leisure time.     

Adoption and maintenance of physical activity: Planning interventions in young, middle-aged, and older adults

Young, middle-aged, and older adults in orthopaedic outpatient rehabilitation (N?=?373) were randomly assigned to either an interviewer-assisted or a standard-care self-administered planning intervention. Physical activity planning consisted of specifying action plans to facilitate action initiation, and coping plans to overcome barriers. The interviewer-assisted condition led to more complete action plans and a longer duration of physical activities up to six months after discharge. Regarding coping planning, older and middle-aged adults benefited more from interviewer-assisted planning while younger adults benefited more from self-administered planning. Planning as such was found to be an effective tool for enactment irrespective of chronological age. The delayed effect of coping planning on enactment suggests that coping planning is important for long-term maintenance.     

Visual and oculomotor selection: links, causes and implications for spatial attention

Natural scenes contain far more information than can be processed simultaneously. Thus, our visually guided behavior depends crucially on the capacity to attend to relevant stimuli. Past studies have provided compelling evidence of functional overlap of the neural mechanisms that control spatial attention and saccadic eye movements. Recent neurophysiological work demonstrates that the neural circuits involved in the preparation of saccades also play a causal role in directing covert spatial attention. At the same time, other studies have identified separable neural populations that contribute uniquely to visual and oculomotor selection. Taken together, all of the recent work suggests how visual and oculomotor signals are integrated to simultaneously select the visual attributes of targets and the saccades needed to fixate them.     

The relationship between aging expectations and various modes of physical activity among aging adults

ObjectivePrevious research has indicated that older adults who expect decline and disease with age are less likely to engage in aerobic exercise. This study explores the influence that different types of aging expectations have on various modes of physical activity (PA) among aging adults.Design & methodsCommunity-dwelling adults aged 41–97 years (M = 70.8, SD = 12.8, n = 247) completed a questionnaire including the Physical Activity Scale for the Elderly, the Expectations Regarding Aging (ERA) Survey, and a number of demographic, socio-economic, and medical covariates.ResultsBivariate analyses revealed significant relationships between overall ERA scores and multiple modes of PA, but not at multivariate levels. Bivariate analyses of the ERA sub-scales revealed significant associations among PA and the physical health ERA sub-scale but not mental health or cognitive function ERA sub-scales. In the multivariate analyses, higher physical health ERA was correlated with strenuous sport and recreational physical activities after adjusting for all covariates among aging adults without restrictions of daily activity (OR = 1.01, CI = 1.00–1.02, n = 194).ConclusionsThe association between aging expectations and PA appears to be dependent on the type of aging expectation (i.e., physical health), the mode or intensity of PA, and the functional abilities of the aging adult.     

Telephone versus mail interventions for maintenance of physical activity in older adults.

Although telephone and mail are often used to promote physical activity adoption, their ability to produce long-term maintenance is unclear. In this study, 140 men and women aged 50-65 years received 1 year of telephone counseling to adopt higher (i.e., more vigorous) versus lower intensity (i.e., moderate) exercise. After 1 year, participants were rerandomized to a 2nd year of contact via (a) telephone and mail or (b) predominantly mail. Participants who were prescribed higher intensity exercise and received predominantly mail had better exercise adherence during the maintenance year than those who received telephone and mail. Both strategies were similarly effective in promoting maintenance in the lower intensity condition. Results suggest that after successful adoption of physical activity with the help of telephone counseling, less intensive interventions are successful for physical activity maintenance in older adults.     

Mediators of behavior change in two tailored physical activity interventions for adolescent girls

ObjectivesIt has been suggested that the lack of knowledge regarding the mechanisms responsible for behavior change may be responsible for the low levels of effectiveness in physical activity interventions among youth. While it is common for physical activity interventions to cite a theoretical framework, few test the validity of their constructs using an established mediation analysis technique. The purpose of this study was to identify mediators of physical activity behavior change in two tailored interventions for adolescent girls.DesignThis study involved an experimental design.MethodsParticipants (N=161) were randomly allocated to a control (CON) group, an intervention based on the Health Promotion (HP) Model or an intervention developed from the HP Model that included two processes from the Transtheoretical Model (THP). Both interventions included school-based education sessions, individual counseling sessions, and two physical activity sessions completed with the participants' mothers. Measures were assessed prior to the intervention, at post-intervention and at a 6-month follow-up. The following constructs were included in the mediation analyses: perceived benefits, perceived barriers, self-efficacy, exposure to models, social support, interpersonal norms, planning, stimulus control, and counterconditioning.ResultsPerceived benefits, perceived barriers, self-efficacy, and commitment to planning satisfied the criteria for mediation in the THP intervention. Self-efficacy and commitment to planning were identified as mediators in the HP intervention.ConclusionThe results of this study provide evidence that both interventions were successful in increasing physical activity through changes in the theoretical constructs.     

Developing physical activity interventions for youth with cystic fibrosis and congenital heart disease: Learning from their parents

Despite the benefits of physical activity for youth with cystic fibrosis (CF) and congenital heart disease (CHD), most are insufficiently active. More information is required on how to facilitate physical activity in these populations. Although there are no studies that provide information about participation in CF and CHD youth from the perspective of parents, the involvement of caregivers may be an important facilitator to physical activity in youth with chronic diseases.

Objective

This qualitative study explored how the parents of youth with CF and CHD experience physical activity, and parents commented on both their own and their child’s physical activity.

Methods

Twenty-nine parents from a CHD and CF clinic participated in a semi-structured interview, and a thematic analysis of the transcribed data was undertaken.

Results

Parents discussed the numerous benefits and barriers associated with physical activity for both child and self. Role modeling was a critical social process to overcoming barriers. Parents experiences were situated within the broader family context characterized by a prevailing sense of stress and complexity.

Conclusion

By illustrating how the parents of youth with CF and CHD understand the role of physical activity in their and their child’s life, this study provides valuable information regarding the development of interventions to increase physical activity among children with CF and CHD.     

Sensation seeking, impulsive decision-making, and risky sex: implications for risk-taking and design of interventions

In an HIV prevention study, 2949 ninth-grade students in 17 high schools in two Midwestern U.S. cities were administered scales measuring sensation seeking and impulsive decision-making and their separate and combined relationships to a number of indicators of sexual risk-taking. Measures of sexual risk-taking included intentions to have sex, ever had sex, number of lifetime sexual partners, been pregnant or caused a pregnancy, used a condom, used marijuana, had unwanted sex when drunk, had unwanted sex under pressure, said no to sex, used alcohol or partner used alcohol before sex. Strong associations were observed between each of the measures and sexual risk-taking for most of the indicators. Strongest associations were found among sexually active students high on both sensation seeking and impulsive decision-making and weakest associations among students low on both measures. Implications for design of interventions in health campaigns are discussed.     

Appearance-based rejection sensitivity: implications for mental and physical health, affect, and motivation

Appearance-Based Rejection Sensitivity (Appearance-RS) is a personality-processing system characterized by anxious concerns and expectations about being rejected based on one's physical attractiveness. People differ in their sensitivity to rejection based on appearance, with consequences for mental and physical health, self-esteem, affect, and feelings of belonging. Study 1 describes the development and validation of the Appearance-RS scale, its relation to personality variables and to health-related outcomes. Study 2 provides experimental evidence that high Appearance-RS people feel more alone and rejected when asked to think about negative aspects of their appearance. Finally, Study 3 tests ways to reduce the negative effects of receiving an appearance threat among high Appearance-RS participants. Specifically, high Appearance-RS participants who engaged in self-affirmation (thought of their personal strengths) or received a secure attachment prime (thought of a close, caring relationship) were buffered from the negative effects of an appearance threat on subsequent state self-esteem and mood.     

Improved episodic integration through enactment: implications for aging

Enactment may improve memory for verb phrases by facilitating episodic integration of object-action components into a unitized whole. It is unclear, however, whether the influence of enactment on episodic integration is related to or independent of the strength of the preexisting semantic relationship between components. To address this issue, the authors examined the influence of enactment on memory for lists of semantically related object-action phrases ("Put money in the wallet") and semantically unrelated phrases created by repairing these objects and actions to make phrases that were unusual but still were possible to perform ("String a thread through the wallet," "Put money in the napkin"). As such, phrases in the related and unrelated lists were matched for familiarity of the individual components and differed only in the associative strength of the object-action relationship. Although verbatim recall of unrelated lists was poorer under standard verbal encoding conditions, enactment succeeded in bringing performance to the level of related lists, indicating that enactment's influence on episodic integration was independent of the semantic relatedness of the object and action components. Analysis of partial recall errors (accurate recall of only one component) suggested that enactment benefited recall in the unrelated lists by improving memory for the action and reducing fragmentation of the association, providing further support for the unitization view. This pattern of results was replicated in normal older adults, a population that exhibits particular difficulty with episodic memory for unrelated associations. The cognitive mechanisms by which enactment may improve episodic integration in both younger and older adults are discussed.     

Cognitive style and suicidal behaviour: implications for therapeutic intervention, research lacunae and priorities

Cognitive style is a well-established theoretical construct but there is considerable ambiguity in the way it has been used and uncertainty regarding the nature of its role in suicide. There is no evidence that specific cognitive dispositions prime people for suicide but there are indications that suicide is associated with a constriction in cognitive style. This constriction leads to decrements in problem-solving and information processing that can be addressed in therapeutic contexts. To help a suicidal person become a better problem-solver is not a trivial task but the evidence suggests that enriching cognitive styles through the development of thinking skills is possible when the therapy session is construed as a learning collaboration.     

Interrelationships among biological markers of aging, health, activity, acculturation, and cognitive performance in late adulthood

In this study a structural equation model of predictors of age differences in cognitive performance in late adulthood was developed. Biological markers of aging (vision, hearing, vibration sense, forced expiratory volume, and grip strength) were used as indicators of a latent variable called BioAge. A sample of 180 community-dwelling women aged 60 to 90 years was assessed. Results showed that BioAge explained all of the age-related variance in cognitive test performance. Physical health and physical activity had direct effects on BioAge. Measures of acculturation explained non-age-related variance in cognitive test performance. Some variables used as biomarkers also explained individual differences in measures of crystallized intelligence and perceptual speed. It is concluded that the association between biomarkers and cognition in old age is due to more than a common statistical association with age.     

Reciprocal relationships between three aspects of physical self-concept,vigorous physical activity,and lung function: A longitudinal study among late adolescents

ObjectivesThis prospective study, of older adolescents, investigated relationships between three aspects of physical self-concept, vigorous physical activity and lung function. In particular, physical competence, general appearance evaluations and body areas satisfaction were expected to predict subsequent physical activity, which, in turn, was expected to explain variation in lung function. In line with the reciprocal effect model, bi-directorial relationships were also tested. Gender was expected to moderate hypothesized relationships.DesignA longitudinal design, with three measurement points (baseline, 2-month follow-up, and 14-month follow-up) was employed.Method551 late adolescents (15–18 years old) provided self-reported data on physical activity, physical competence, body areas satisfaction, and appearance evaluation. Body weight, height, and a lung function index (forced expiratory volume in 1 s, FEV₁) were measured at baseline and at the 14-month follow-up.ResultsModerated mediation analyses indicated that physical competence at baseline predicted vigorous physical activity (2-month follow-up) among young men and women. Baseline body satisfaction and appearance evaluation were also related to vigorous physical activity (2-month follow-up) and this relationship was stronger for men. Vigorous physical activity predicted FEV₁ (14-month follow-up) and this relationship was stronger among women. The reciprocal pattern of relationships was not confirmed.ConclusionsFindings suggest that health promoting interventions should focus particularly on vigorous physical activity among young women, for example by boosting their physical competence.     

Constructs of physical activity behaviour in children: The usefulness of Social Cognitive Theory

Objectives

The purpose of this study was to investigate the relationships among several Social Cognitive Theory (Bandura, 2004) constructs (e.g., self-efficacy) and children’s physical activity behaviours.

Design

Children from six elementary schools (N = 479) in grades 4th to 6th from five different school districts in the Southwestern USA participated in this study by completing a sociocognitive instrument as well as wearing a pedometer for five school days.

Methods

Previously validated scales were combined and administered to all children in order to examine the relationships among five constructs (self-efficacy, outcome expectations, social support, barriers, and goals) and physical activity participation was measured via pedometer. Data analyses included a two-step approach with confirmatory factor analysis followed by structural equation modelling.

Results

The confirmatory factor analyses indicated an adequate fit of the specified model. The structural model fit statistics also suggested that the data fit the specified model: χ² (8, N = 476) = 24.44, p = 0.00, χ²/df = 3.06, GFI = 0.98, AGFI = 0.96, CFI = 0.93, RMSEA = 0.07. The model explained 15% of the variance in social support, 11% of the variance in goals, 11% of the variance in barriers, 9% of the variance in outcome expectations, and 2% of the variance in physical activity. Self-efficacy was a strong predictor of total social support, total number of barriers, and outcome expectations.

Conclusions

This study supports the use of Social Cognitive Theory in understanding the constructs of physical activity behaviour in children, however, very little variance in behaviours was explained. There is a need to also investigate environmental influences on children’s decisions to be physically active.     

Arousal and physiological toughness: implications for mental and physical health

From W.B. Cannon's identification of adrenaline with "fight or flight" to modern views of stress, negative views of peripheral physiological arousal predominate. Sympathetic nervous system (SNS) arousal is associated with anxiety, neuroticism, the Type A personality, cardiovascular disease, and immune system suppression; illness susceptibility is associated with life events requiring adjustments. "Stress control" has become almost synonymous with arousal reduction. A contrary positive view of peripheral arousal follows from studies of subjects exposed to intermittent stressors. Such exposure leads to low SNS arousal base rates, but to strong and responsive challenge- or stress-induced SNS-adrenal-medullary arousal, with resistance to brain catecholamine depletion and with suppression of pituitary adrenal-cortical responses. That pattern of arousal defines physiological toughness and, in interaction with psychological coping, corresponds with positive performance in even complex tasks, with emotional stability, and with immune system enhancement. The toughness concept suggests an opposition between effective short- and long-term coping, with implications for effective therapies and stress-inoculating life-styles.     

Cognitive ability and motivational interventions: Their effects on performance outcomes

A laboratory experiment was conducted to examine the effects of cognitive ability, task interests, goal setting, and feedback on perceived competence, intrinsic motivation, performance, and satisfaction with performance. Data were collected from 90 introductory psychology students performing one of two computer-based tasks. Results indicated that the motivational interventions interacted with cognitive ability in relation to intrinsic motivation, perceived competence, and satisfaction with performance. Implications are discussed within the framework of cognitive resources theory and goal-setting theory.     

Plasticity: implications for opioid and other pharmacological interventions in specific pain states

The spinal mechanisms of action of opioids under normal conditions are reasonably well understood. The spinal effects of opioids can be enhanced or reduced depending on pathology and activity in other segmental and nonsegmental pathways. This plasticity will be considered in relation to the control of different pain states using opioids. The complex and contradictory findings on the supraspinal actions of opioids are explicable in terms of heterogeneous descending pathways to different spinal targets using multiple transmitters and receptors--therefore opioids can both increase and decrease activity in descending pathways. These pathways could exhibit considerable plasticity. There is increasing evidence that delta opioid receptor agonists have the potential to replace morphine as major analgesics with reduced side-effect profiles. The concept of preemptive analgesia, based on preventing the induction of some of the negative plastic influences on opioid controls and the detrimental effects of pain, is sound, but experimental verification in the clinical setting is difficult. For example, a delayed compensatory upregulation of inhibitory systems, particularly in inflammation, may counter persistent painful inputs. Combination therapy with opioids may be beneficial in many pain states where either negative influences are blocked or inhibitory controls are enhanced. Finally, developmental aspects of these systems are discussed in connection with the treatment of pain in young children, where inhibitory systems in the spinal cord are immature.     

Women,sex, and HIV: social and contextual factors,meta-analysis of published interventions,and implications for practice and research

This article is focused on examining social and contextual factors related to HIV-risk behavior for women. Specifically, this article has three main purposes: to review the literature on selected social and contextual factors that contribute to the risk for the heterosexual transmission of HIV and AIDS, to review and conduct a meta-analysis of HIV-prevention interventions targeting adult heterosexual populations, and to suggest future directions for HIV-prevention intervention research and practice. Results suggest that the HIV-prevention interventions reviewed for this article had little impact on sexual risk behavior, that social and contextual factors are often minimally addressed, and that there was a large gap between research and the practice of HIV-prevention intervention.     

The implications of cortical recruitment and brain morphology for individual differences in inhibitory function in aging humans

The authors assessed individual differences in cortical recruitment, brain morphology, and inhibitory task performance. Similar to previous studies, older adults tended toward bilateral activity during task performance more than younger adults. However, better performing older adults showed less bilateral activity than poorer performers, contrary to the idea that additional activity is universally compensatory. A review of the results and of extant literature suggests that compensatory activity in prefrontal cortex may only be effective if the additional cortical processors brought to bear on the task can play a complementary role in task performance. Morphological analyses revealed that frontal white matter tracts differed as a function of performance in older adults, suggesting that hemispheric connectivity might impact both patterns of recruitment and cognitive performance.
