自我决定理论认为，如果行为是自主激励的，那么行为改变就会发生并持续下去。行为的自主动机理论上被认为是一般因果取向量表中自主取向的个体差异和相关社会情境中自主取向程度的函数。我们对128名患者进行了为期23个月的B月极低热量减肥计划，并进行了为期23个月的随访。分析证实了以下预测：（a）减肥动机更自主的参与者会更经常地参加该计划，在计划期间减轻更多体重，并在随访时保持更大的体重减轻，（B）被试的自主减肥动机可以通过他们的自主性取向和被试对健康环境所创造的人际氛围的自主性感知来预测。护理人员。
Self-determination theory proposes that behavior change will occur and persist if it is autonomously motivated. Autonomous motivation for a behavior is theorized to be a function both of individual differences in the autonomy orientation from the General Causality Orientations Scale and of the degree of autonomy supportiveness of relevant social contexts. We tested the theory with 128 patients in a B-month, very-low-calorie weight-loss program with a 23-month follow-up. Analyses confirmed the predictions that(a) participants whose motivation for weight loss was more autonomous would attend the program more regularly, lose more weight during the program, and evidence greater maintained weight loss at follow-up, and (b) participants' autonomous motivation for weight loss would be predicted both by their autonomy orientation and by the perceived autonomy supportiveness of the interpersonal climate created by the health-care staff.
