We examined whether constructs outlined in self-determination theory (Deci & Ryan, 2002), namely, autonomy-supportive and controlling motivational climates and autonomous and controlled motivation, were related to attitudes toward performance-enhancing drugs (PEDs) in sport and drug-taking susceptibility. We also investigated moral disengagement as a potential mediator. We surveyed a sample of 224 competitive athletes (59% female; M age = 20.3 years; M = 10.2 years of experience participating in their sport), including 81 elite athletes. Using structural equation modeling analyses, our hypothesis proposing positive relationships with controlling climates, controlled motivation, and PEDs attitudes and susceptibility was largely supported, whereas our hypothesis proposing negative relationships among autonomous climate, autonomous motivation, and PEDs attitudes and susceptibility was not supported. Moral disengagement was a strong predictor of positive attitudes toward PEDs, which, in turn, was a strong predictor of PEDs susceptibility. These findings are discussed from both motivational and moral disengagement viewpoints.
我们考察了自我决定理论（Deci 和 Ryan，2002）中概述的结构，即支持自主和控制的动机氛围以及自主和受控动机，是否与运动中的兴奋剂态度和吸毒倾向有关。我们还研究了道德脱离作为潜在的中介因素。我们调查了 224 名竞技运动员（59%为女性；平均年龄为 20.3 岁；平均参与运动的经验为 10.2 年），包括 81 名精英运动员。使用结构方程模型分析，我们提出的与控制氛围、受控动机和兴奋剂态度和易感性呈正相关的假设得到了很大支持，而我们提出的与自主氛围、自主动机和兴奋剂态度和易感性呈负相关的假设则没有得到支持。道德脱离是对兴奋剂持积极态度的强有力预测因素，而这种态度反过来又是兴奋剂易感性的强有力预测因素。这些发现从动机和道德脱离的角度进行了讨论。
