The study investigated the affective and cognitive responses (including self-beliefs about personality attributes and the level of certainty associated with these beliefs) to the repeated delivery of performance feedback (failure vs. success) across adaptive and maladaptive dimensions of perfectionism. Participants completed questionnaires and a mental rotation computer task, to which they received feedback for. Performance feedback was delivered at Time point 1 (initial) and at Time point 2 (repeated). Results showed that maladaptive perfectionism predicted increased negative affect after initial failure and decreased confidence in self-descriptiveness ratings for negative-related personality attributes after initial success, with these confidence levels further decreasing following repeated success. Adaptive perfectionism predicted higher self-ratings on positive-related personality attributes but only after initial success. The findings suggest that changes in responses across adaptive and maladaptive perfectionism are influenced by experiences of success rather than failure. Adaptive perfectionism also seemed resilient to input from external sources while maladaptive perfectionism appeared more susceptible to such influence. However, given the preliminary nature of the present findings, further research in this area is needed to understand the impact of performance feedback on the self-concept across these two dimensions of perfectionism.

这项研究调查了在完美主义的适应性和适应不良维度上反复传递绩效反馈（失败与成功）的情感和认知反应（包括关于人格属性的自我信念和与这些信念相关的确定性水平）。参与者完成了调查表和一个心理旋转计算机任务，他们收到了反馈。在时间点1（初始）和时间点2（重复）提供了性能反馈。结果表明，适应不良的完美主义预言了初始失败后负面影响会增加，并且在初始成功后对与负面相关的人格属性的自我描述等级的信心会下降，而随着重复成功，这些信心水平会进一步下降。适应性完美主义预测了与积极相关的人格属性的更高自我评价，但仅在最初获得成功之后。研究结果表明，适应性和适应不良性完美主义对策的变化受成功经验而非失败经验的影响。适应性完美主义似乎也能抵抗来自外部来源的输入，而适应不良的完美主义似乎更容易受到这种影响。但是，鉴于当前发现的初步性质，需要在这一领域进行进一步研究，以了解绩效反馈对完美主义这两个维度上的自我概念的影响。研究结果表明，适应性和适应不良性完美主义对策的变化受成功经验而非失败经验的影响。适应性完美主义似乎也能抵抗来自外部来源的输入，而适应不良的完美主义似乎更容易受到这种影响。但是，鉴于当前发现的初步性质，需要在这一领域进行进一步研究，以了解绩效反馈对完美主义这两个维度上的自我概念的影响。研究结果表明，适应性和适应不良性完美主义对策的变化受成功经验而非失败经验的影响。适应性完美主义似乎也能抵抗来自外部来源的输入，而适应不良的完美主义似乎更容易受到这种影响。但是，鉴于当前发现的初步性质，需要在这一领域进行进一步研究，以了解绩效反馈对完美主义这两个维度上的自我概念的影响。
