OBJECTIVE Researchers have called for an approach that examines the conditions under which perfectionistic strivings (PS) may be beneficial or detrimental to psychological functioning. We adopted a self-regulation perspective and tested whether individual differences in self-regulation (procrastination, emotion regulation) moderate PS's relationships with achievement and well-being in an academic/work-related achievement context. METHOD A sample of 183 preservice teachers participated in a study that combined "traditional" longitudinal assessment (six performance situations over a 9-month period) with repeated ambulatory assessment (measuring well-being, procrastination, and emotion regulation during a total of 910 preparation phases that preceded performance situations). RESULTS Mean levels of achievement, well-being, and emotion regulation were found to be stable over time, whereas procrastination decreased on average across preparation phases. Results from latent variable interaction models indicated that individual differences in intraindividual change in procrastination over time moderated the relationship between PS and well-being (but not achievement) in the expected direction: The less individuals decreased in procrastination over time, the more negative the relationship between PS and well-being was. Contrary to expectations, we found no evidence of a moderating effect of emotion regulation. CONCLUSION The study contributes to a nuanced perspective on the adaptiveness of PS.

完美主义的追求对幸福和成就有益还是有害？作为调节因素的拖延和情绪调节测试。


目标 研究人员呼吁采取一种方法来检验完美主义追求（PS）在哪些条件下可能有益于或有害于心理功能。我们采用自我调节的视角，并测试了自我调节（拖延、情绪调节）的个体差异是否会调节 PS 与学术/工作相关成就背景下的成就和幸福感的关系。方法 183 名职前教师参与了一项研究，该研究将“传统”纵向评估（9 个月期间的六种表现情况）与重复流动评估（在总共 910 名准备期间测量幸福感、拖延和情绪调节）相结合。性能情况之前的阶段）。结果发现，随着时间的推移，成就、幸福感和情绪调节的平均水平保持稳定，而拖延症在准备阶段的平均水平有所下降。潜变量交互模型的结果表明，随着时间的推移，个体拖延变化的个体差异按照预期的方向调节了 PS 和幸福感（而不是成就）之间的关系：随着时间的推移，拖延程度下降的个体越少，这种关系就越负面。 PS和幸福之间是。与预期相反，我们没有发现情绪调节具有调节作用的证据。结论 这项研究有助于对 PS 的适应性有一个细致入微的视角。
