The present study examines the factor structure of the Japanese version of the Posttraumatic Growth Inventory (PTGI-J) among bereaved family members who lost loved ones to cancer after home-based palliative care in Japan. It evaluates the relationships between total score, each PTGI-J domain, and participants' having a religious belief, gender, age, relationship to the patient, and time since patient death.
Bereaved family members (n = 849) completed the PTGI-J and a demographic questionnaire. The factor structure was tested using confirmatory factor analysis (CFA), and univariate analysis was used to test hypotheses.
Confirmatory factor analysis showed that the current sample moderately fitted to both 4-factor and 5-factor models. Univariate analysis revealed that having a religious belief and gender were associated with all domains and total PTGI-J score. Age, time since patient death, and relationship to the patient showed significant differences with the domains of PTGI-J.
Clinicians may be able to adjust the support they provide based on patients' personal characteristics. Future research should look at the mechanisms of PTG by examining the role of rumination, social support, and emotional distress among bereaved family members of patients with cancer.
本研究考察了日本居家姑息治疗后因癌症失去亲人的丧亲家庭成员中，日文版创伤后成长问卷（PTGI-J）的因子结构。它评估了总分、PTGI-J各领域与参与者的宗教信仰、性别、年龄、与患者的关系以及患者死亡后的时间之间的关系。
丧亲家庭成员（n = 849）完成了PTGI-J和一份人口统计学调查问卷。使用验证性因子分析（CFA）对因子结构进行检验，并使用单变量分析来检验假设。
验证性因子分析表明，当前样本对四因子模型和五因子模型均有适度拟合。单变量分析显示，宗教信仰和性别与所有领域及PTGI-J总分相关。年龄、患者死亡后的时间以及与患者的关系在PTGI-J各领域存在显著差异。
临床医生或许能够根据患者的个人特征调整他们提供的支持。未来的研究应通过考察癌症患者丧亲家庭成员中的沉思、社会支持和情绪困扰的作用，来探究创伤后成长的机制。
