Objective: The PA Counseling (PAC) trial tested a primary care intervention using Self-Determination Theory (SDT) as the guiding framework. This paper presents specific results related to SDT constructs in a physical activity (PA) context. Specifically, whether patients who received both brief autonomy supportive PA counseling from their health-care provider and intensive (3 month) autonomy supportive counseling from a PA counselor would report greater levels of autonomy support, autonomous motivation, perceived competence and PA adoption, than patients receiving only brief counseling. In addition, we tested Williams’ SDT process model in the context of PA adoption.Method: Measures of autonomous motivation and perceived competence for PA were measured at baseline and 6 weeks. PA was assessed at baseline and 13 weeks. An autonomy support index was calculated by multiplying minutes of counseling by perceptions of autonomy support. Group differences in autonomy support, autonomous motivation, perceived competence and PA were examined. The SDT process model of PA adoption was tested via path analysis.Results: The results showed higher autonomy support and autonomous motivation at 6 weeks and higher PA levels at 13 weeks for the experimental group. The SDT process model for PA adoption showed that autonomous motivation and perceived competence at 6 weeks significantly predicted 13-week PA for the experimental group.Conclusions: This study provides a rigorous field test of SDT theory in a PA context. It demonstrates the versatility and applicability of the SDT model for health behavior change. SDT-trained PA counselors appear to provide valuable contribution to facilitating patient behavior change, by increasing patient autonomous motivation for PA.  相似文献

Based on self-determination theory (SDT), this study investigated, whether the three central SDT variables (perceived autonomy support, autonomous motivation and self-care competence), were associated with engagement in physical activity (PA) among patients with type 2 diabetes when the effect of a wide variety of other important life-context factors (perceived health, medication, duration of diabetes, mental health, stress and social support) was controlled for. Patients from five municipalities in Finland with registry-based entitlement to a special reimbursement for medicines used in the treatment of type 2 diabetes (n = 2866, mean age 63 years, 56% men) participated in this mail survey in 2011. Of all measured explanatory factors, autonomous motivation was most strongly associated with engagement in PA. Autonomous motivation mediated the effect of perceived autonomy support on patients’ PA. Thus, perceived autonomy support (from one’s physician) was associated with the patient’s PA through autonomous motivation. This result is in line with SDT. Interventions for improved diabetes care should concentrate on supporting patients’ autonomous motivation for PA. Internalizing the importance of good self-care seems to give sufficient energy to maintain a physically active lifestyle.  相似文献

A longitudinal study tested the self-determination theory (SDT) process model of health behavior change for glycemic control within a randomized trial of patient activation versus passive education. Glycosylated hemoglobin for patients with Type 2 diabetes (n=159) was assessed at baseline, 6 months, and 12 months. Autonomous motivation and perceived competence were assessed at baseline and 6 months, and the autonomy supportiveness of clinical practitioners was assessed at 3 months. Perceptions of autonomy and competence were promoted by perceived autonomy support, and changes in perceptions of autonomy and competence, in turn, predicted change in glycemic control. Self-management behaviors mediated the relation between change in perceived competence and change in glycemic control. The self-determination process model fit the data well.  相似文献

ObjectiveRheumatoid arthritis (RA) is an autoimmune disease, characterised by high-grade systemic inflammation, pain, and swollen joints. RA patients have an increased risk for cardiovascular disease (CVD). This study examined if a 3-month individualised RA-tailored exercise programme with one-on-one Self-Determination Theory (SDT)-based support for physical activity (PA) facilitated autonomous motivation, increased PA behaviour, and induced greater improvements in cardiovascular and RA-related disease characteristics, and wellbeing in RA, compared to a standard provision tailored exercise programme.Methods115 RA patients were randomised into either the SDT-based psychological intervention + exercise programme (experimental group) or an exercise programme only (control group). Cardiorespiratory fitness (primary outcome), self-reported PA, disease characteristics, CVD risk, wellbeing, and SDT constructs were assessed at baseline (pre-intervention), 3 months (post-intervention), 6 months, and 12 months follow-up. Mixed linear modeling was used to examine within- and between participant changes in these outcome measures.ResultsIn 88 patients with complete baseline data, cardiorespiratory fitness did not change from baseline to 3-, 6- or 12 months in either group. CVD risk, disease characteristics, wellbeing, and need satisfaction did not change, with the exception of diastolic blood pressure. Significant group by time interaction effects were found for functional ability (6- & 12-months), CVD risk (6-months) and PA (3-months). Autonomous motivation increased and controlled motivation decreased more in the experimental group compared to the control group at 3 months.ConclusionsDespite improving quality of motivation for exercise, no changes in cardiorespiratory fitness or other psychological and physiological health outcomes were found. This suggests more intensive support is needed when initiating an exercise programme to achieve health benefits in RA.  相似文献

This study qualitatively examined the motivationally relevant behaviors of key social agents in specializing sport participants. Seventy-nine participants (9–18 years old) from 26 sports participated in semi-structured focus groups investigating how coaches, parents, and peers may influence motivation. Using a critical-realist perspective, an inductive content analysis indicated that specializing athletes perceived a multitude of motivationally relevant social cues. Coaches’ and parents’ influences were related to their specific roles: instruction/assessment for coaches, support-and-facilitation for parents. Peers influenced motivation through competitive behaviors, collaborative behaviors, evaluative communications, and through their social relationships. The results help to delineate different roles for social agents in influencing athletes’ motivation.  相似文献

This cross-sectional study applied self-determination theory to understand the relationship between coaching behaviors, psychological need satisfaction, and intrinsic motivation among young Chinese athletes from 2 universities in Macao, China (N = 208). In the path model with the demographics adjusted, coaching behaviors (training instruction, democratic behaviors, autocratic behaviors, social support, and positive feedback) and need satisfaction (perceived autonomy, competence, and relatedness) explained 44% of the variance in intrinsic motivation. We also found indirect effects of some coaching behaviors on intrinsic motivation through satisfying the psychological needs. Furthermore, independent self-construal significantly moderated the relationship between perceived relatedness and intrinsic motivation.  相似文献

Past studies have found that risk perceptions of suffering from diseases play an important role in the development of intentions to perform physical activity (PA). According to the behaviour motivation hypothesis, perceived risk could be positively and directly related to PA, but this possibility has been ignored and/or underestimated. Accounting for recent methodological developments on the importance of study design and risk perception assessment, the purpose of the present study was to examine the risk-perceptions-PA relationship among older adults. Participants (N=143) aged from 61 to 70 years initially underwent measurement of risk perceptions, baseline PA, socio-demographic and health factors. Six months later, they were asked about their PA participation. Multiple regression analyses revealed that perceived risk of suffering from diseases and conditions without regular PA participation was an independent positive predictor of later PA, over and beyond baseline behaviour, socio-demographic and health variables. This study fills a gap in the existing literature on the PAs of older adults and reveals that risk perceptions are directly linked to their participation. In addition, it extends existing knowledge in health psychology on the behaviour motivation hypothesis, and emphasises the necessity of methodological adjustments when assessing the risk-perception-behaviour relationship.  相似文献

Most U.S. adults, even more so those with psychiatric conditions like obsessive-compulsive disorder (OCD), do not engage in the recommended amount of physical activity (PA), despite the wide array of physical and mental health benefits associated with exercise. Therefore, it is essential to identify mechanistic factors that drive long-term exercise engagement so they can be targeted. Using the science of behavior change (SOBC) framework, this study examined potential predictors of long-term exercise engagement as a first step towards identifying modifiable mechanisms, in individuals with OCD, such as PA enjoyment, positive or negative affect, and behavioral activation. Fifty-six low-active patients (mean age = 38.8 ± 13.0, 64% female) with a primary diagnosis of OCD were randomized to either aerobic exercise (AE; n = 28) or health education (HE; n = 28), and completed measures of exercise engagement, PA enjoyment, behavioral activation, and positive and negative affect at baseline, postintervention, and 3-, 6-, and 12-month follow-up. Significant predictors of long-term exercise engagement up to 6-months postintervention were baseline PA (Estimate = 0.29, 95%CI [0.09, 0.49], p = .005) and higher baseline PA enjoyment (Estimate = 1.09, 95%CI [0.30, 1.89], p = .008). Change in PA enjoyment from baseline to postintervention was greater in AE vs. HE, t(44) = −2.06, p = .046, d = −0.61, but endpoint PA enjoyment did not predict follow-up exercise engagement above and beyond baseline PA enjoyment. Other hypothesized potential mechanisms (baseline affect or behavioral activation) did not significantly predict exercise engagement. Results suggest that PA enjoyment may be an important modifiable target mechanism for intervention, even prior to a formal exercise intervention. Next steps aligned with the SOBC framework are discussed, including examining intervention strategies to target PA enjoyment, particularly among individuals with OCD or other psychiatric conditions, who may benefit most from long-term exercise engagement’s effects on physical and mental health.  相似文献

The aim of this study was twofold: first, to examine the stability of the hypothesized conceptual model of motor development (without and with including various types of motivation) when children are followed up one-year later, and second to examine longitudinally whether changes in one model variable predict changes in other variables, according to the hypothesized pathways in the model. A sample of 361 Spanish students (50.7% girls, 8–11 years old) voluntarily participated in this study. In relation to the first aim, structural equation modeling revealed the expected positive relationship between the model variables in both measurement times. That is: actual motor competence (MC) predicted physical activity (PA) (p < .001), perceived MC mediated the relationship between actual MC and PA (p < .001), and autonomous motivation mediated the relationship between perceived MC and PA (p < .05). Moreover, the comparison of the invariance analysis showed non-practical differences between the unconstrained model and the constrained model, supporting the stability of the model over time. In relation to the second aim, the hypothesized model in Time 2 controlling for Time 1 values showed that changes in children’s actual MC positively predicted changes in their perceived MC (p < .001), which in turn, predicted changes in their autonomous motivation (p < .001), and PA (p < .001) at Time 2. Based on these findings Physical Education teachers are recommended to foster children’s actual and perceived MC as well as their autonomous motivation over time in order to promote PA strategies for lifelong health.  相似文献

We applied the trans-contextual model (TCM) to examine the effects of middle school students’ perceived autonomy support from their physical education (PE) teachers on autonomous motivation toward PE in school and, critically, autonomous motivation toward, and actual participation in, leisure-time physical activity (PA). The research adopted a three-wave prospective design enabling the modeling of change in the TCM constructs over time. Middle school students (N = 248) aged from 12 to 16 years reported their perceived autonomy support, autonomous motivation in PE, autonomous motivation toward leisure-time PA, attitudes, subjective norms, perceived behavioral control (PBC), intentions for PA in leisure-time, and leisure-time PA participation. The psychological constructs and leisure-time PA were measured at baseline (T0) and at a first follow-up occasion (T1) 5 weeks later. Another measure of PA was taken at a second follow-up occasion (T2) a further 5 weeks later. A single-indicator structural equation model using residualized change scores revealed that perceived autonomy support predicted autonomous motivation in PE (β = .345), and autonomous motivation in PE predicted autonomous motivation for leisure-time PA (β = .484). Autonomous motivation toward leisure-time PA predicted attitudes (β = .425), subjective norms (β = .264), and PBC (β = .517). Autonomous motivation toward leisure-time PA (β = .376), attitude (β = .231), and subjective norms (β = .185) predicted intentions toward leisure-time PA, and intentions predicted PA (β = .198). Findings extend research on the TCM by demonstrating its efficacy in predicting change in middle school students’ autonomous motivation across PE and leisure-time contexts, and accounting for change in intentions toward, and actual participation in, leisure-time PA.  相似文献

Self-Determination Theory (SDT) suggests that individuals with greater basic psychological needs satisfaction and autonomous motivation are more likely to adopt physical activity (PA). However, few longitudinal studies have examined these processes in exercise initiates outside the context of a formalized intervention. Further, an implicit yet relatively unexplored tenet of SDT is that when behaviors are closely connected to what is meaningful to individuals, those behaviors are more likely to be maintained. This study had two aims: (a) to examine SDT and a sense of meaning in life (MIL) in relation to PA in previously inactive exercise initiates, and (b) to determine whether daily measurement of MIL, mood, and PA impacts PA engagement. Upon joining a fitness center, participants (N = 160; M age = 43.3 years; 77% female) were recruited for a longitudinal study of PA adoption. Participants were randomized to a daily measurement condition (self-monitoring) where they reported daily MIL, mood, and PA or to an attention control condition. All participants self-reported their PA, basic psychological needs satisfaction, behavioral exercise regulation, and MIL at baseline, 4-weeks, and 12-weeks after starting an exercise program. Longitudinal path models were used to examine the relationships among study variables. Cross-sectionally, SDT constructs were largely related to PA in the expected directions. After accounting for SDT processes, baseline MIL was associated with greater PA at 4-weeks (p = .028). There were no differences in PA, SDT constructs, or MIL between the measurement self-monitoring and control groups. MIL predicted PA adoption above and beyond SDT predictors in previously inactive adults. Combined SDT and MIL intervention approaches may enhance PA adoption, and further research should explore their roles in PA adoption and maintenance.  相似文献

We tested the hypothesis that a psychosocial dental intervention formulated in terms of self-determination theory would increase patients’ perceived competence and autonomous motivation for dental care and would decrease their plaque and gingivitis over a seven month period, compared to standard dental treatment. We also tested a process model in which the intervention was expected to increase perceived dental competence and autonomous motivation, that they would be positively associated with oral health behaviors (i.e., brushing and flossing), which was expected to decrease plaque and, in turn, decrease gingivitis. We also examined whether: changes in perceived competence and autonomous motivation would mediate the effect of the intervention on dental-health behaviors; dental-health behaviors would mediate the links from changes in perceived competence and autonomous motivation to change in plaque; and change in plaque would mediate the relation of dental health behaviors to change in gingivitis. Finally, we examined the fit of the overall model with structural equation modelling. Results supported all predictions.

Teachers’ support of student autonomy in physical education (PE) is believed to be important for students’ motivation and outcomes in PE. We tested the hypothesis that an intervention designed to help teachers to be more autonomy supportive in teaching their students to use learning strategies (relative to standard teaching) would increase students’ perceived autonomy support from the teachers, perceived competence, autonomous motivation, use of learning strategies and their exertion, participation, and grades in PE over a school year. We also tested a self-determination theory (SDT) process model. Experimental effects of the intervention yielded significant positive effects on changes in perceived autonomy support, learning strategies defined as absorption and effort regulation, as well as for performance (i.e., grades). In testing the SDT process model with SEM, most of the predicted paths were significantly supported.  相似文献

Background: Children's perceived competence and intrinsic motivation are assumed to be very high at the outset of schooling. However, how they change and how they relate to each other and to academic achievement across early schooling years remain open to question. Aims: This 3‐year longitudinal study was aimed at examining the following questions. Do children's perceived competence and intrinsic motivation about reading and mathematics change across the first 3 years of schooling? Do their perceived competence and intrinsic motivation differ according to academic domains? Do their perceived competence and intrinsic motivation relate to their academic achievement in each academic domain? Sample: A total of 115 elementary schoolchildren (63 boys and 52 girls) were examined in first grade (mean age = 84,5 months, SD = .67) and for the next 2 years. Method: Children responded to questionnaires about their perceived competence and intrinsic motivation in reading and mathematics. Year‐end grades in these two subjects were used as a measure of performance. Results: Changes in perceived competence and intrinsic motivation, and between‐year intercorrelations, were observed to differ according to academic domains and gender. Intrinsic motivation did not make a significant contribution to academic achievement at either school grade or in any academic domain, whereas perceived competence was significantly related to achievement at each school grade in both reading and mathematics. Conclusions: Differences between boys and girls observed in this study were not linked to a specific domain and cannot be attributed to gender‐role stereotypes. Girls appeared to be more precocious in differentiating their competence and intrinsic motivation according to academic domain, as well as in being able to process and integrate information about their ability from past performances in a domain to judge their competence in the same domain.  相似文献

OBJECTIVES: To provide a methodological overview of a computerized intervention to promote leisure time physical activity (PA) and to apply self-determination theory (SDT) to PA initiation to better understand the psychological mechanisms underlying PA frequency, intensity, and duration in previously-sedentary individuals. DESIGN: Based on SDT, two computerized personal trainers were developed for use with sedentary young adults. One personal trainer was designed to be need-supportive, empathic, and structured while the other was designed to be more controlling, evaluative, and judgmental. METHOD: Participants are randomly assigned to work with either the need-supportive or controlling computerized personal trainer. They complete a series of 7 weekly training sessions. In between training sessions, participants complete daily records of PA behaviors and experiences including autonomous self-regulation and perceived competence for PA and PA frequency, intensity, and duration. POTENTIAL CONTRIBUTIONS: The design of this intervention and its theoretical basis have important implications for advancing the field of exercise science specifically and health behavior change more broadly. Computerized interventions have the benefit of standardizing intervention content as well as reducing clinical contact burden for practitioners. Daily recording procedures reduce the likelihood of retrospection bias and allow for the modeling of (1) daily fluctuations in PA behavior and (2) the psychological mechanisms believed to be involved in PA behavior (e.g., autonomous self-regulation). Finally, as a broad theory of human motivation, SDT is uniquely positioned to offer explanations for the conditions that are likely to promote both the initiation and maintenance of health behavior change.  相似文献

Avoidance of culturally diverse peers undermines the benefits of multicultural teams. Using uncertainty reduction theory, we argue that team members’ cultural intelligence (CQ; the capability to work effectively in culturally diverse settings) and language competence (the ability to communicate in a language) exert main and synergistic effects on avoidance behaviors. We further propose that avoidance negatively predicts individuals’ task performance (behaviors that contribute to team outcomes) and voice behaviors (giving suggestions to improve the status quo). Put together, we test a moderated mediation model where the mediating role of avoidance between CQ and outcomes of task performance and voice behaviors is moderated by language competence. Our results, based on data collected from multicultural team members at three time points, showed no main effects of CQ and language competence on avoidance. Instead, we found synergistic effects such that CQ was negatively related to avoidance only when language competence was high. Avoidance was negatively related to peer-rated task performance and voice behaviors. Conditional process analyses supported our moderated mediation hypothesis, suggesting that avoidance explains why people with higher CQ and higher language competence have higher task performance and voice behaviors.  相似文献

The aim of this study was twofold: first, to investigate whether perceived motor competence (PMC) mediates the relation between actual motor competence (AMC) and physical activity (PA) according to the conceptual model of motor development, and second to examine the role of different motivational regulations (i.e., intrinsic, identified, introjected, and external regulation) in the relationship between PMC and PA. A sample of 504 Spanish students (46.2% girls, 8–12 years old) voluntarily participated in this study. In relation to the first aim, structural equation modeling revealed that PMC indeed mediates the association between AMC and PA. In relation to the second aim, positive associations between AMC and PMC (β = 0.32, p < .001), which in turn was positively related to intrinsic and identified regulations (β = 0.46 and β = 0.43 respectively, p < .001), were found. The model showed direct paths from intrinsic and introjected regulation to PA (β = 0.27 and β = 0.22, p < .05) and indirect paths from PMC through intrinsic motivation to PA (β = 0.13, p < .05). This study confirms that intrinsic motivation mediates the association between PMC and PA. Strategies targeting to build and develop children’s AMC and PMC, and fostering children’s intrinsic motivation should be targeted to promote children’s PA engagement and motor development.  相似文献

This study tested a self‐determination theory (SDT) process model of oral health and subjective dental well‐being. The results showed that: (1) patients' perceptions of autonomy‐supportive dental professionals were significantly positively predictive of patients' psychological needs satisfaction in treatment; (2) needs satisfaction was significantly related to perceived dental competence (positive), autonomous motivation (positive), and controlled motivation (negative) for dental care; (3) perceived competence was significantly positively, and controlled motivation was significantly negatively associated with self‐rated oral health and oral‐health‐related quality of life; (4) autonomous motivation for dental treatment was significantly positively associated with valuing continued dental treatment; and (5) the three oral‐health‐related variables were all significantly positively linked to subjective dental well‐being. A structural equation model supported the SDT process model.  相似文献
