Although skin-picking is a relatively common behaviour, data concerning factors which underlie skin-picking severity and functional impairment caused by picking are still limited. In the present study we examined whether some emotion regulation strategies (cognitive reappraisal and expressive suppression) and personality features influence skin-picking in a university sample; the moderating role of personality traits in the relationship between emotion regulation strategies and skin-picking was also considered. A total sample of 252 adults (mean age 24.03; SD = 5.66) completed the Skin-Picking Scale-Revised, Temperament and Character Inventory and Emotion Regulation Questionnaire. The linear regression analyses indicated that the use of cognitive reappraisal as emotion regulation strategy decrease skin-picking severity. Reduced novelty seeking and reduced self-directedness were identified as significant predictors of skin-picking severity, whereas decreased self-directedness and elevated cooperativeness predicted functional impairment caused by skin-picking. Further moderation analysis revealed that cognitive reappraisal decreases skin-picking severity only among individuals with low and moderate novelty seeking, however, not among those with high novelty seeking. These results indicate that emotion regulation strategies and specific personality traits are important factors associated with skin-picking behaviours in a university sample. Further research is needed to establish the link between emotion regulation strategies and personality traits in clinical sample.
虽然皮肤搔抓是一种相对常见的行为，但有关导致搔抓严重程度和功能障碍的潜在因素的数据仍然有限。在本研究中，我们在一个大学生样本中研究了一些情绪调节策略（认知重评和表达抑制）和人格特征是否会影响皮肤搔抓；还考虑了人格特质在情绪调节策略与皮肤搔抓之间关系中的调节作用。共有 252 名成年人（平均年龄 24.03；SD=5.66）完成了修订后的皮肤搔抓量表、气质与性格问卷和情绪调节问卷。线性回归分析表明，认知重评作为情绪调节策略可以降低皮肤搔抓的严重程度。较低的新奇寻求和较低的自我导向被确定为皮肤搔抓严重程度的显著预测因素，而较低的自我导向和较高的合作性则预测了皮肤搔抓导致的功能障碍。进一步的调节分析表明，认知重评仅在新奇寻求较低和中等的个体中降低皮肤搔抓的严重程度，而在新奇寻求较高的个体中则没有。这些结果表明，情绪调节策略和特定的人格特征是与大学生样本中皮肤搔抓行为相关的重要因素。需要进一步的研究来确定临床样本中情绪调节策略和人格特质之间的联系。
