In the large literature on creativity and mental illness, relatively few studies have explored anhedonia—impairments in anticipating, seeking, and experiencing rewards. This project explored self-reported creativity in a sample of adults who differed in depressive anhedonia, determined via face-to-face structured clinical interviews. Participants completed measures of everyday creativity (engaging in common creative behaviors and hobbies), creative self-concepts (creative self-efficacy, creative personal identity, and self-rated creativity in different domains), and creative achievements. Compared to the control group (n = 52), people in the anhedonia group (n = 22) had significantly higher engagement in little-c creative activities (medium effect size). Effect sizes for self-rated creativity and creative achievement were either small or near-zero. Taken together, the findings suggest that anhedonia deserves more attention in future research on motivational aspects of creativity.

抑郁的快感缺失和创造性的自我概念、行为和成就

在关于创造力和精神疾病的大量文献中，很少有研究探讨快感缺失——在期待、寻求和体验奖励方面的障碍。该项目通过面对面的结构化临床访谈确定了在抑郁性快感缺乏症方面存在差异的成年人样本中的自我报告创造力。参与者完成了日常创造力（从事共同的创造性行为和爱好）、创造性自我概念（创造性自我效能感、创造性个人身份和不同领域的创造性自我评价）和创造性成就的测量。与对照组（n  = 52）相比，快感缺乏组（n = 22) 在 little-c 创意活动中的参与度明显更高（中等效果）。自评创造力和创造性成就的影响大小要么很小，要么接近于零。综上所述，研究结果表明，在未来关于创造力的动机方面的研究中，快感缺乏值得更多关注。
