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 Mainland China.
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.
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's α of 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.
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.
被诊断患有癌症的儿童的父母常常经历高度的疾病不确定性。本研究评估了中国大陆版儿童癌症父母不确定性感知量表（PPUS-CC）的心理测量特性。
对420名父母的研究人群进行探索性因素分析（EFA）和验证性因素分析（CFA）。参与者还被给予社会支持问卷，并使用自评焦虑量表、扎里特负担访谈量表和自评抑郁量表进行评估，以测试与PPUS-CC的关联并获得该量表的临界值。
中国大陆版PPUS-CC包括14个条目，EFA提取出两个因素，可解释54.56%的方差。两个因素的克朗巴哈α系数在0.830至0.877之间。PPUS-CC的维度与其他量表显示出统计学关联，临界值为42.5。
中国大陆版PPUS-CC作为一种可靠、有效且易于使用的临床工具，可在临床环境中作为筛查工具，以识别有高危心理问题的父母。
