目的：以自我决定理论（SDT）为指导框架，对初级保健干预进行检验。本文介绍了在体育活动（PA）背景下SDT结构的具体结果。具体来说，接受医疗保健提供者的简短自主支持性个人护理咨询和个人护理咨询师的强化（3个月）自主支持性咨询的患者是否比只接受简短咨询的患者报告更高水平的自主支持、自主动机、感知能力和个人护理采用。此外，我们在PA采用的背景下测试了Williams的SDT过程模型。方法：分别在基线和第6周测量PA的自主动机和感知能力。在基线和13周时评估PA。自主支持指数是通过将咨询时间乘以自主支持的感知来计算的。研究小组在自主支持、自主动机、感知能力和PA方面的差异。通过通径分析对PA采用的SDT过程模型进行了检验。结果：实验组在第6周具有较高的自主支持和自主动机，在第13周具有较高的PA水平。SDT过程模型显示，第6周的自主动机和感知能力显著预测了实验组第13周的学习能力。结论：本研究在PA背景下对SDT理论进行了严格的实地检验。它展示了SDT模型在健康行为改变方面的多功能性和适用性。sdt训练的PA咨询师通过增加患者对PA的自主动机，似乎对促进患者行为改变做出了有价值的贡献。(c) 2006 Elsevier Ltd.版权所有。
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. (c) 2006 Elsevier Ltd.
