Psychometric properties of the Chinese version of the Parent Perception of Uncertainty Scale(PPUS)among parents of children with cancer diagnosis

中文版父母用疾病不确定感量表在恶性肿瘤患儿父母群体中的信效度检验

Objective:Parents of children diagnosed with cancer often experience high levels of illness uncertainty.This study evaluated the psychometric properties of the Chinese Version of the Parent Perception of Uncertainty Scale for Childhood Cancer(PPUS-CC)in China's Mainland.Methods:Exploratory factor analysis(EFA)and confirmatory factor analysis(CFA)were performed using study population of 420 parents.The participants were also given the social support questionnaire and assessed using the Self-Rating Anxiety Scale,Zarit Burden Interview,and Self-Rating Depression Scale to test the association with PPUS-CC and obtain the cut-off of the scale.Results:The Chinese version of PPUS-CC includes 14 items,and two factors were extracted by EFA,which could explain the 54.56%variances.The Cronbach'sαof two factors ranged from 0.830 to 0.877.The dimensions of PPUS-CC show statistical association with other scales,and the cut-off is 42.5.Conclusion:The Chinese version of PPUS-CC,as a reliable,valid,and easy-to-use clinical tool,can be adapted in clinical settings as a screening tool to recognize parents with high-risk psychological problems.

目的当孩子被确诊为恶性肿瘤的时候,父母通常会经历高水平的疾病不确定感(llness uncertainty,IU),本研究主要对中文版父母用疾病不确定感量表(Parents’Perception Uncertainty in Illness for Childhood Cancer,PPUS-CC)的信效度进行检验。方法本研究共纳入420名恶性肿瘤患儿父母,应用探索性因子分析和验证性因子分析进行信效度分析,另外社会支持量表、焦虑自评量表、抑郁自评量表及照顾负担量表被用于测量PPUS-CC的相关性以及截断值。结果最终的中文版PPUS-CC包括2个因子14个条目,共可解释54.56%的变异量。2个因子的Cronbach's a系数分别为0.830和0.877。中文版PPUS-CC和其他量表的相关性较强,它的截断值是42.5。结论中文版PPUS_CC条目较少、信效度较高,能够识别具有高水平情绪困扰的父母,适合在临床使用。
