采用纵向随机试验，检验了自我决定理论(SDT)干预和戒烟健康行为改变的过程模型(N=1006)。成年吸烟者被招募参加吸烟者健康研究，并被分配到强化治疗或社区护理。参与者相对较穷，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大的自主性支持，并报告了更多的自主性和能力动机。他们还报告了更多的药物使用和明显更大的禁欲。结构方程模型分析证实了SDT过程模型，在该模型中，感知到的自主性支持导致自主动机和能力动机的增加，进而导致更大程度的停止。自主性支持在自主动机、感知能力和戒烟的内化中的因果作用得到支持。
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.
