A longitudinal randomized trial tested the self-determination theory (SDT) intervention and process model of health behavior change for tobacco cessation (N = 1006). Adult smokers were recruited for a study of smokers' health and were assigned to intensive treatment or community care. Participants were relatively poor and undereducated. Intervention patients perceived greater autonomy support and reported greater autonomous and competence motivations than did control patients. They also reported greater medication use and significantly greater abstinence. Structural equation modeling analyses confirmed the SDT process model in which perceived autonomy support led to increases in autonomous and competence motivations, which in turn led to greater cessation. The causal role of autonomy support in the internalization of autonomous motivation, perceived competence, and smoking cessation was supported.
一项纵向随机试验对戒烟的自我决定理论（SDT）干预及健康行为改变的过程模型进行了测试（N = 1006）。招募成年吸烟者参与一项关于吸烟者健康的研究，并将他们分配至强化治疗组或社区护理组。参与者相对贫困且受教育程度较低。与对照组患者相比，干预组患者感受到了更多的自主支持，且报告称具有更强的自主和胜任动机。他们还报告了更多的药物使用情况以及显著更高的戒烟率。结构方程模型分析证实了自我决定理论的过程模型，即感知到的自主支持会导致自主和胜任动机的增加，进而导致更高的戒烟率。自主支持在自主动机内化、感知胜任及戒烟方面的因果作用得到了支持。
