the importance of supporting autonomy and Perceived Competence in facilitating long term tobacco abstinence
Annals of Behavioral Medicine, 2009Co-Authors: Geoffrey C Williams, Christopher P Niemiec, Heather Patrick, Edward L DeciAbstract:Background—The Public Health Service (PHS) Guideline for Treating Tobacco Use and Dependence (1) recommends supporting autonomy and Perceived Competence to facilitate tobacco abstinence. Purpose—To evaluate the effectiveness of an intensive tobacco-dependence intervention based on self-determination theory (SDT) and intended to support autonomy and Perceived Competence in facilitating long-term tobacco abstinence. Methods—One thousand and six adult smokers were recruited into a randomized cessationinduction trial. Community care participants received cessation pamphlets and information on local treatment programs. Intervention participants received the same materials and were asked to meet four times with counselors over six months to discuss their health in a manner intended to support autonomy and Perceived Competence. The primary outcome was 24-month prolonged abstinence from tobacco. The secondary outcome was 7-day point prevalence tobacco abstinence at 24 months post-intervention. Results—Smokers in the intervention were more likely to attain both tobacco abstinence outcomes and these effects were partially mediated by change in both autonomous self-regulation and Perceived Competence from baseline to six months. Structural equation modeling confirmed the SDT model of health-behavior change in facilitating long-term tobacco abstinence. Conclusions—An intervention based on SDT and consistent with the PHS Guideline, which was intended to support autonomy and Perceived Competence, facilitated long-term tobacco abstinence.

Annals of Behavioral Medicine, 2009Co-Authors: Geoffrey C Williams, Christopher P Niemiec, Heather Patrick, Richard M Ryan, Edward L DeciAbstract:The Public Health Service (PHS) Guideline for Treating Tobacco Use and Dependence (Fiore et al. 2000) recommends supporting autonomy and Perceived Competence to facilitate tobacco abstinence. The aim of the study was to evaluate the effectiveness of an intensive tobacco-dependence intervention based on self-determination theory (SDT) and intended to support autonomy and Perceived Competence in facilitating long-term tobacco abstinence. One thousand and six adult smokers were recruited into a randomized cessation–induction trial. Community care participants received cessation pamphlets and information on local treatment programs. Intervention participants received the same materials and were asked to meet four times with counselors over 6 months to discuss their health in a manner intended to support autonomy and Perceived Competence. The primary outcome was 24-month prolonged abstinence from tobacco. The secondary outcome was 7-day point prevalence tobacco abstinence at 24 months postintervention. Smokers in the intervention were more likely to attain both tobacco abstinence outcomes and these effects were partially mediated by change in both autonomous self-regulation and Perceived Competence from baseline to 6 months.

computer assisted intervention improves patient centered diabetes care by increasing autonomy support
Health Psychology, 2007Co-Authors: Geoffrey C Williams, Martin F Lynch, Russell E GlasgowAbstract:Objective: To determine if a patient-centered, computer-assisted diabetes care intervention increased Perceived autonomy support, Perceived Competence (from self-determination theory), and if these constructs mediated the effect of the intervention on ADA/NCQA recommended diabetes care outcomes. Design: A randomized controlled trial of 866 adult type 2 diabetes patients in heterogeneous primary care settings in Colorado. Main Outcome Measures: Perceived autonomy support, Perceived Competence, patient satisfaction, glycemic control (HbAlc), ratio of total to HDL cholesterol, diabetes distress, and depressive symptoms. Results: The computer-assisted intervention increased patient perception of autonomy support relative to a computer-based control condition (p <.05). Change in Perceived Competence partially mediated the effects of increased autonomy support on the change in lipids, diabetes distress, and depressive symptoms. The construct of autonomy support was found to be separate from that of patient satisfaction. Conclusions: A patient-centered, computer-assisted intervention was effective in improving diabetes self-management outcomes, in part, because it increased patients' perception that their autonomy was supported which changed Perceived Competence. These findings support the self-determination model for health behavior change and the chronic care model and support the further study of the use of these technologies to motivate patients to improve their health outcomes.

a self determination process model of physical activity adoption in the context of a randomized controlled trial
Psychology of Sport and Exercise, 2007Co-Authors: Michelle Fortier, Shane N Sweet, Tracey L Osullivan, Geoffrey C WilliamsAbstract:Abstract 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.

variation in Perceived Competence glycemic control and patient satisfaction relationship to autonomy support from physicians
Patient Education and Counseling, 2005Co-Authors: Geoffrey C Williams, Holly A Mcgregor, Diane King, Candace C Nelson, Russell E GlasgowAbstract:There is considerable variation in care provided to patients with diabetes related to metabolic control, preventive services, and degree of patient-centered support. This study evaluates the relation of self-determination theory (SDT) constructs of clinician autonomy support, and patient Competence to glycemic control, depressive symptoms, and patient satisfaction from baseline surveys of 634 patients of 31 Colorado primary care physicians participating in a program to improve diabetes care. Spearman correlations of autonomy support from one’s clinician with patient Competence, HbA1c, depressive symptoms and satisfaction were significant ( r =− 0.11 to 0.55, P< 0.05). Structural equation modeling demonstrated that autonomy support was significantly related to Perceived Competence, depressive symptoms, patient satisfaction, and indirectly to glycemic control. Perceived Competence was significantly related to depressive symptoms, patient satisfaction and glycemic control. Further, the motivation constructs from SDT accounted for 5% of the variance in glycemic control, 8% of the variance in depression, and 42% of the variance in patient satisfaction. Quality improvement efforts need to pay greater attention to patient Competence, satisfaction, and depression, in addition to glycemic control. Clinician autonomy support was found to be reliably measured and moderately correlated with psychosocial and biologic outcomes related to diabetes self-management. These results suggest training clinicians to increase their support of patient autonomy may be one important avenue to improve diabetes outcomes. © 2004 Elsevier Ireland Ltd. All rights reserved.

testing a self determination theory process model for promoting glycemic control through diabetes self management
Health Psychology, 2004Co-Authors: Geoffrey C Williams, Holly A Mcgregor, Allan Zeldman, Zachary R Freedman, Edward L DeciAbstract: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.

predicting motivational regulations in physical education the interplay between dispositional goal orientations motivational climate and Perceived Competence
Journal of Sports Sciences, 2003Co-Authors: Martyn Standage, Joan L Duda, Nikos NtoumanisAbstract:In this study, we examined the main and interactive effects of students' goal orientations, Perceived Competence and perceptions of the motivational climate on the motivational styles advanced by self-determination theory. The participants were 328 British secondary school students aged 13.6 +/- 0.6 years (mean +/- s). Moderated hierarchical regression analyses revealed task orientation, Perceived Competence and perceptions of a mastery climate to be positive predictors of self-determined styles of motivation. Perceived Competence in physical education was negatively associated with amotivation. Significant interaction effects for mastery climate x task orientation and for ego orientation x Perceived Competence emerged. The results indicate that: (1) for students endorsing a high task orientation, the perception that the class climate was high in mastery cues was associated with increased intrinsic motivation; and (2) for students high in ego orientation, the belief that one was competent increased, while perceptions of inCompetence attenuated intrinsic motivation. Additionally, a three-way interaction between ego orientation, performance climate and Perceived Competence emerged. In light of achievement goal and self-determination frameworks, we propose that studying the potential interplay between both individual and situational goal perspectives and the moderating effect of Perceived Competence may further enhance our understanding of motivation in physical education.

a self determination approach to the understanding of motivation in physical education
British Journal of Educational Psychology, 2001Co-Authors: Nikos NtoumanisAbstract:Background. It is widely acknowledged that Physical Education (PE) can play a potentially important role in enhancing public health by creating positive attitudes toward exercise and by promoting health-related fitness programmes. However, these initiatives will have limited success if students are not motivated to participate actively in their PE lessons. Aim. A sequence of motivational processes, proposed by Vallerand (1997), was tested in this study. The sequence has the formsocial factors !psycho- logical mediators !types of motivation !consequences'. Sample. Participants were 424 British students aged 14± 16 years from Northwest England. Method. Questionnaires were used to measure cooperative learning, self- referenced improvement, and choice of tasks (social factors), Perceived Competence, autonomy, and relatedness (psychological mediators), intrinsic motivation, identification, introjection, external regulation, and amotivation (types of motivation), and boredom, effort, and future intention to exercise (consequences). Results. A SEM analysis showed that Perceived Competence was the major psychological mediator. Intrinsic motivation was related to positive con- sequences, whereas external regulation and amotivation were predictors of negative consequences. A multisample analysis indicated that the model was largely invariant across gender. Conclusions. The findings underline the importance of Perceived Competence and intrinsic motivation in compulsory PE.
