（1）评估癌症复发恐惧水平（FCR）、社会支持、应对方式和创伤后成长水平；（2）确定与创伤后成长相关的因素；（3）比较在肿瘤学急症患者主要照顾者中，按创伤后成长水平的高低（无或少创伤后成长 vs. 中等或高创伤后成长），患者和主要照顾者的特征。采用横断面研究设计。数据通过北台湾一个医学中心最近6个月经历过肿瘤学急症的癌症患者-照顾者对的方便抽样收集。完成癌症治疗的患者在重症监护室。对患者进行了疾病严重程度、身体状况和人口统计学和临床特征的评估。使用一套问卷评估了主要照顾者的FCR、社会支持、应对方式和创伤后成长。我们发现，80.8%的主要照顾者报告了中等或高创伤后成长，19.2%报告了无或少创伤后成长。主要照顾者的更大创伤后成长与更多患者肿瘤学急症的经历、更年轻的照顾者年龄、更高的照顾者FCR得分和照顾者采用积极应对行为有关。如果主要照顾者经历更少的患者肿瘤学急症、年龄较大、报告的FCR较低，且不经常使用积极应对策略，则更不可能报告创伤后成长。开发基于情境的模拟来促进对肿瘤学急症的照料，并提供心理咨询以鼓励积极应对，有助于主要照顾者从肿瘤学急症中恢复情绪，并促进成长。版权所有© 2023 Elsevier Inc. 保留所有权利。

(1) To assess the levels of fear of cancer recurrence (FCR), social support, coping styles, and posttraumatic growth; (2) to identify factors associated with posttraumatic growth; and (3) to compare patient and primary caregiver characteristics by level of posttraumatic growth (no-to-little posttraumatic growth vs. moderate-to-high posttraumatic growth) in the primary caregivers of patients with an oncologic emergency.A cross-sectional study design was adopted. Data were collected by convenience sampling of cancer patient-caregiver dyads who experienced an oncologic emergency within the last 6 months at a medical center in northern Taiwan. The patients, who had completed cancer treatment, were in an intensive care unit. They were assessed for disease severity, physical performance, and demographic and clinical characteristics. Primary caregivers were assessed for FCR, social support, coping styles, and posttraumatic growth using a set of questionnaires. We found that 80.8% of primary caregivers reported moderate-to-high posttraumatic growth and 19.2% reported no-to-little posttraumatic growth.Greater posttraumatic growth in primary caregivers was associated with experiencing more patient oncologic emergencies, younger caregiver age, a higher caregiver FCR score, and caregivers' use of active coping behaviors. Caregivers were less likely to report posttraumatic growth if they experienced fewer patient oncologic emergencies, were older, reported lower FCR, and used active coping strategies less frequently.Developing scenario-based simulations to facilitate caregiving for an oncologic emergency and providing psychological counseling to encourage active coping can help primary caregivers recover emotionally from an oncologic emergency and facilitate growth.Copyright © 2023 Elsevier Inc.
