目标：基于自决理论[SDT； Deci & Ryan，1985。人类行为的内在动机和自我决定。纽约：Plenum Press]，这项研究调查了对处方锻炼计划的坚持程度较高的超重/肥胖个体与较少坚持的超重/肥胖个体在感知自主支持、心理需求满足、自主动机、运动行为、运动相关认知和总体幸福感方面的差异。此外，本研究通过测试自主支持作为心理需求满足的预测因子，自主支持和心理需求满足作为动机调节的预测因子，以及自主支持、心理需求满足和动机调节作为行为、认知和幸福结果的预测因子，探索了 SDT 中嵌入的动机序列。方法：超重/肥胖个体（N = 49；M 身体质量指数 = 38.75）完成了一份涉及所有上述变量的多部分调查问卷。使用出勤记录评估参与者对计划的遵守情况。结果：多级回归分析显示，在运动处方结束时，与坚持较少的人相比，坚持较多的人报告说，克服运动障碍的自我效能感更高。此外，随着时间的推移，那些表现出更高依从性的人表现出相关性需求的增加。对于整个样本，需求满足预测了自我决定调节，总的来说，这些结构对应于整个项目中与适应性运动相关的结果和总体幸福感。结论：根据结果，处方计划锻炼将受益于创建通过促进心理需求满足来促进自我决定的服务。 (c) 2006 Elsevier Ltd. 保留所有权利。
Objectives: Based on Self-Determination Theory [SDT; Deci & Ryan, 1985. Intrinsic motivation and self determination in human behavior. New York: Plenum Press], this study examined differences in perceived autonomy support, psychological need satisfaction, self-determined motivation, exercise behaviour, exercise-related cognitions and general well-being, between overweight/obese individuals who demonstrated greater adherence to an exercise on prescription programme and those who adhered less. In addition, this study explored the motivational sequence embedded in SDT by testing autonomy support as a predictor of psychological need satisfaction, autonomy support and psychological need satisfaction as predictors of the motivational regulations, and autonomy support, psychological need satisfaction and the motivational regulations as predictors of behavioural, cognitive and well-being outcomes.Method: Before commencing, at 1-month, and upon terminating a 3-month exercise on prescription programme, overweight/obese individuals (N = 49; M Body Mass Index = 38.75) completed a multisection questionnaire tapping all aforementioned variables. Participants' adherence to the scheme was assessed using attendance records.Results: Multilevel regression analyses revealed that, at the end of the exercise prescription, those individuals who adhered more reported more self-efficacy to overcome barriers to exercise versus those who adhered less. In addition, those individuals who showed greater adherence demonstrated an increase in relatedness need satisfaction over time. For the whole sample, need satisfaction predicted self-determined regulation, and collectively, these constructs corresponded to adaptive exercise related outcomes and general well-being throughout the programme.Conclusions: Based on the results it appears that exercise on prescription schemes would benefit from creating services that foster self-determination via the facilitation of psychological need satisfaction.
