Significant levels of anxiety, depression and insomnia symptoms are found in cancer patients. Perfectionism, arousability and coping have been associated with these psychological symptoms in the general population but their role among cancer patients remains to be assessed. This study examined the longitudinal relationships between perfectionism and psychological symptoms (anxiety, depression, insomnia), and the intermediate role of the arousability trait and coping strategies.
Participants (N = 853) completed the Multidimensional Perfectionism Scale, the Coping with Health Injuries and Problems questionnaire and the Arousal Predisposition Scale at the perioperative period (T1), and the Hospital Anxiety and Depression Scale and the Insomnia Severity Index two months later (T2).
Higher levels of perfectionism (T1) were correlated with greater symptoms of anxiety, depression and insomnia (T2). Moderated mediation models indicated that arousability contributed to the association of perfectionism with all symptoms, with stronger associations found in men than in women. Coping was a significant pathway between perfectionism and anxiety, with associations of a comparable magnitude across sexes.
If these results are replicated by future longitudinal studies, they would suggest that perfectionist cancer patients are at a higher risk of experiencing psychological symptoms, partly through their hyperarousability and the coping strategies they use.
癌症患者中存在显著程度的焦虑、抑郁和失眠症状。在普通人群中，完美主义、易激惹性和应对方式与这些心理症状有关，但它们在癌症患者中的作用仍有待评估。本研究考察了完美主义与心理症状（焦虑、抑郁、失眠）之间的纵向关系，以及易激惹性特质和应对策略的中介作用。
参与者（N = 853）在围手术期（T1）完成多维完美主义量表、应对健康损伤和问题问卷以及易激惹性倾向量表，两个月后（T2）完成医院焦虑抑郁量表和失眠严重程度指数。
更高水平的完美主义（T1）与更严重的焦虑、抑郁和失眠症状（T2）相关。调节中介模型表明，易激惹性促成了完美主义与所有症状之间的关联，男性中的关联比女性更强。应对方式是完美主义与焦虑之间的重要途径，两性之间的关联程度相当。
如果这些结果能被未来的纵向研究所重复，将表明完美主义的癌症患者出现心理症状的风险更高，部分原因是他们的过度易激惹性和所采用的应对策略。
