Employing Self-Determination Theory (Deci & Ryan, 1985) as a theoretical framework, this study examined psychological need satisfaction and motivational regulations as predictors of psychological and behavioural outcomes in exercise referral (ER). ER patients (N?=?293; mean age 54.49) completed the measures of motivational regulations, psychological need satisfaction, health-related quality of life, life satisfaction, anxiety, depression and physical activity at entry, exit and 6 months following the end of a supervised exercise programme. Change in (Δ) intrinsic motivation during the scheme significantly predicted adherence and Δ habitual physical activity. Δ psychological need satisfaction from entry to exit significantly predicted Δ habitual physical activity from exit to 6-month follow-up. Δ psychological need satisfaction significantly predicted Δ motivational regulation and Δ psychological outcomes. Contrary to expectations, Δ self-determined regulation did not significantly predict Δ psychological outcomes during the structured part of the scheme, however, it did significantly predict Δ in psychological outcomes from exit to 6-month follow-up. These findings expand on cross-sectional research to demonstrate that psychological need satisfaction during supervised ER longitudinally predicts motivational regulation and psychological outcomes up to 6 months after a structured programme.  相似文献

Rates of chronic diseases are high among Black South Africans but few studies have tested cognitive-behavioural health-promotion interventions to reduce this problem. We tested the efficacy of such an intervention among adolescents in a cluster-randomised controlled trial. We randomly selected 9 of 17 matched pairs of schools and randomised one school in each pair to the cognitive-behavioural health-promotion intervention designed to encourage health-related behaviours and the other to a human immunodeficiency virus (HIV)/sexually transmitted disease (STD) risk-reduction intervention that served as the control. Interventions were based on social cognitive theory, the theory of planned behaviour and qualitative data from the target population. Data collectors, blind to participants' intervention, administered confidential assessments at baseline and 3, 6 and 12 months post-intervention. Primary outcomes were fruit and vegetable consumption and physical activity. Participants were 1057 grade 6 learners (mean age = 12.4 years), with 96.7% retained at 12-month follow-up. Generalised estimating equations revealed that averaged over the follow-ups, a greater percentage of health-promotion intervention participants than HIV/STD control participants met 5-a-Day fruit and vegetable and physical activity guidelines. The intervention also increased health-promotion knowledge, attitude and intention, but did not decrease substance use or substance-use attitude and intention. The findings suggest that theory based and contextually appropriate interventions may increase health behaviours among young adolescents in sub-Saharan Africa.  相似文献

There is widespread use of self-report measures of driving behaviour in the traffic psychology literature, despite the frequent criticism that such measures are subject to social desirability bias. However, no research has yet investigated the more recently developed measures of driving anxiety and avoidance behaviour for socially desirable responding. Furthermore, relatively little research has investigated the issue of socially desirable responding on self-reported driver behaviour in general, and that which does exist has several shortcomings. The present study used a repeated measures design to assess the effect of social desirability on a measure of driving avoidance, the Driving and Riding Avoidance Scale (DRAS), and the Driver Behaviour Questionnaire (DBQ). A sample of 228 undergraduate students completed the DRAS, DBQ and a measure of socially desirable responding in class, which constituted a public place, and then again 2 months later in the privacy of their homes. None of the DBQ items were significantly different across the two locations. However, two of the DRAS general avoidance items were higher in the public setting, perhaps demonstrating the effect of socially desirable responding on driving avoidance due to environmental or practical concern. Nevertheless, overall it appears as though the DRAS and DBQ are not particularly vulnerable to socially desirable responding, although further well-designed research on the effects of such bias on these and other self-report measures of driving behaviour should be undertaken.  相似文献

The present study examined the role that group norms, group identification, and imagined audience (in-group vs. out-group) play in attitude–behavior processes. University students ( N =187) participated in a study concerned with the prediction of consumer behavior. Attitudes toward drinking their preferred beer, subjective norm, perceived behavioral control, group norm, and group identification were assessed. Intentions and perceived audience reactions to consumption were assessed. As expected, group norms, identification, and imagined audience interacted to influence likelihood of drinking one's preferred beer and perceived audience reactions. High identifiers were more responsive to group norms in the presence of an in-group audience than an out-group audience. The present results indicate that audience concerns impact upon the relationship between attitudes and behavior.  相似文献

Pharmacologic and Behavioral Withdrawal From Addictive Drugs   总被引:1,自引:0,他引:1  
ABSTRACT— Recent theories suggest that drug withdrawal does not motivate drug use and relapse. However, data now show that withdrawal produces complex changes over time in at least two symptoms (i.e., negative affect and urges) that are highly predictive of relapse. Evidence suggests that falling levels of the drug in the blood and interruption of the drug self-administration ritual both affect these symptoms. Both of these forms of withdrawal motivate renewed drug use in addicted individuals.  相似文献

This study examined the hypothesis that romantic competence (RC) skills would be demonstrated behaviorally during dating couple problem solving interactions. A coding system was developed for RC behavior, and its validity was examined through its association with relationship satisfaction and negative affect expressed. A total of 106 emerging adult dating couples in different‐sex relationships were assessed using the Romantic Competence Interview for Emerging Adults, and they participated in a dyadic problem‐solving interaction coded for RC behavior and negative affect. Men's behavioral RC was positively associated with both his and his partner's satisfaction. Behavioral RC was also more associated with satisfaction than was negative affect. Implications for the utility of teaching RC skills in young couples are discussed.  相似文献

Engagement in online interventions, defined as the extent to which participants are involved in and attentive to the contents of the intervention, has been shown to predict treatment outcome. However, participant engagement and program completion are often quite low. Aiming to provide insights that could help improve engagement, this study explores engagement in an online intervention for young couples with breast cancer, Couplelinks, by describing the development of a method to assess engagement, presenting a framework for understanding varying engagement levels, and discussing strategies used by Couplelinks facilitators to work with participants of differing engagement levels. The measure of engagement developed for this study was a composite consisting of indices of average completion time, accountability, and attitude. Utilizing this composite measure, the following distinct “couple types,” with varying levels of engagement, were discerned: (a) “keen” couples, (b) “compliant” couples, (c) “apologetic” couples, and (d) “straggling” couples. Facilitators’ approaches to working with each type of couple and suggestions for potential therapeutic applications are discussed. The finding that couples vary in terms of engagement level, and not solely based on facilitator skill and/or involvement, supports the need to better understand the concept of engagement in order to make online interventions more effective.  相似文献

Previous research has supported the theory that acquisition of expertise in any domain is possible for healthy individuals with sufficient deliberate practice, but such an extreme environmental position brings the existence of innate talent into question. The present study investigates the effects of both environmental factors and talent on expert performance in both high school and conservatory-level musicians. Audition scores and accumulated practice time were recorded, and correlated with scores on Gordon's Advanced Measures of Music Audiation and Raven's Progressive Matrices. Higher-level musicians report significantly higher mean levels on innate characteristics such as general intelligence and music audiation, in addition to higher levels of accumulated practice time. These factors together accounted for more of the variance in music performance than practice alone. A multi-factor view is thus shown to be the best explanation for the acquisition of musical expertise.  相似文献

Early periventricular brain lesions can not only cause cerebral palsy, but can also induce a reorganization of language. Here, we asked whether these different functional consequences can be attributed to topographically distinct portions of the periventricular white matter damage. Eight patients with pre- and perinatally acquired left-sided periventricular brain lesions underwent focal transcranial magnetic stimulation to assess the integrity of cortico-spinal hand motor projections, and functional MRI to determine the hemispheric organization of language production. MRI lesion-symptom mapping revealed that two distinct portions of the periventricular lesions were critically involved in the disruption of cortico-spinal hand motor projections on the one hand and in the induction of language reorganization into the contra-lesional right hemisphere on the other hand. Both regions are located in a position compatible with the course of cortico-spinal/cortico-nuclear projections of the primary motor cortex in the periventricular white matter, as determined by the stereotaxic probabilistic cytoarchitectonic atlas developed by the Jülich group.  相似文献

The transition to middle school is often marked by decreased academic achievement and increased emotional stress, and African American children exposed to social risk may be especially vulnerable during this transition. To identify mediators and protective factors, the authors related severity and timing of risk exposure to academic achievement and adjustment between 4th and 6th grade in 74 African American children. Longitudinal analyses indicated that severity more than timing of risk exposure was negatively related to all outcomes and that language skills mediated the pathway from risk for most outcomes. Transition to middle school was related to lower math scores and to more externalizing problems when children experienced higher levels of social risk. Language skills and parenting served as protective factors, whereas expectations of racial discrimination was a vulnerability factor. Results imply that promoting parenting and, especially, language skills, and decreasing expectations of racial discrimination provide pathways to academic success for African American children during the transition from elementary to middle school, especially those exposed to adversity.  相似文献
