Moral identity and moral disengagement have been linked with doping likelihood. However, experiments testing the temporal direction of these relationships are absent. The authors conducted one cross-sectional and two experimental studies investigating the conjunctive effects of moral identity and moral disengagement on doping likelihood (or intention). Dispositional moral identity was inversely (marginally), and doping moral disengagement, positively, associated with doping intention (Study 1). Manipulating situations to amplify opportunities for moral disengagement increased doping likelihood via anticipated guilt (Study 2). Moreover, dispositional moral identity (Study 2) and inducing moral identity (Study 3) were linked with lower doping likelihood and attenuated the relationship between doping moral disengagement and doping likelihood. However, the suppressing effect of moral identity on doping likelihood was overridden when opportunities for moral disengagement were amplified. These findings support multifaceted antidoping efforts, which include simultaneously enhancing athlete moral identity and personal responsibility alongside reducing social opportunities for moral disengagement.

道德认同和道德脱离与服用兴奋剂的可能性有关。然而，缺乏测试这些关系的时间方向的实验。作者进行了一项横断面研究和两项实验研究，调查道德认同和道德脱离对兴奋剂可能性（或意图）的联合影响。性格道德认同与兴奋剂意图呈负相关（边际相关），而兴奋剂道德脱离则与兴奋剂意图呈正相关（研究 1）。通过操纵局势来扩大道德脱离的机会，通过预期内疚增加服用兴奋剂的可能性（研究 2）。此外，性格道德认同（研究2）和诱导道德认同（研究3）与较低的兴奋剂可能性相关，并减弱了兴奋剂道德脱离与兴奋剂可能性之间的关系。然而，当道德脱离的机会被放大时，道德认同对兴奋剂可能性的抑制作用就被推翻了。这些发现支持多方面的反兴奋剂努力，其中包括同时增强运动员的道德认同和个人责任，同时减少道德脱离的社会机会。
