Hope plays an extremely important role in protecting childhood cancer patients from psychological distress caused by cancer. The availability of a valid and reliable instrument that can accurately assess hope is crucial for the development of interventions to enhance hope among childhood cancer patients. This study aimed to examine the psychometric properties of the Chinese version of the Herth Hope Index (HHI). Chinese childhood cancer patients aged 8-17 years (n = 412) were invited to participate in this cross-sectional study. Participants completed the Chinese translated version of the HHI, the Center for Epidemiology Studies Depression Scale for Children and the Paediatric Quality of Life Inventory 3.0 Cancer Module. Exploratory factor analysis and confirmatory factor analysis were conducted to assess the structural validity of the HHI. Content validity, convergent validity, internal consistency, and test-retest reliability at 2 weeks were also examined. The content validity index for items ranged from 0.8 to 1.0, and that for the scale was 0.9, demonstrating appropriate content validity. There was a positive correlation between HHI and Center for Epidemiology Studies Depression Scale for Children scores and a negative correlation between HHI and Paediatric Quality of Life Inventory 3.0 Cancer Module scores. The results indicated that the Chinese version of the HHI showed reasonable convergent validity and discriminant validity. Exploratory factor analysis yielded a three-factor model, which could explain 82.74% of the total variance. The confirmatory factor analysis results showed that χ/df was 2.20, comparative fit index was 0.98, goodness of fit index was 0.94, and root-mean-square error of approximation was 0.07. Cronbach's alpha was 0.78, indicating good internal consistency. The findings of the study showed that the Chinese version of the HHI (11-item) is a reliable and valid instrument for assessing hope among Chinese childhood cancer patients. Evidence-based interventions can be provided to enhance hope in this population.
希望在保护癌症患儿免受癌症引起的心理困扰方面起着极其重要的作用。拥有一种能够准确评估希望的有效且可靠的工具对于开发增强癌症患儿希望的干预措施至关重要。本研究旨在检验 Herth 希望指数（HHI）中文版的心理测量学特性。本研究邀请了 8-17 岁的中国癌症患儿（n=412）参与横断面研究。参与者完成了 HHI 中文版、儿童流行病学研究抑郁量表和儿童生活质量量表 3.0 癌症模块。进行了探索性因子分析和验证性因子分析以评估 HHI 的结构效度。还检验了内容效度、聚合效度、内部一致性和 2 周时的重测信度。项目的内容效度指数范围为 0.8-1.0，量表的内容效度指数为 0.9，表明具有适当的内容效度。HHI 与儿童流行病学研究抑郁量表得分呈正相关，与儿童生活质量量表 3.0 癌症模块得分呈负相关。结果表明，HHI 中文版具有合理的聚合效度和区分效度。探索性因子分析得出了一个三因素模型，可解释总方差的 82.74%。验证性因子分析结果显示，χ/df 为 2.20，比较拟合指数为 0.98，拟合优度指数为 0.94，近似均方根误差为 0.07。克朗巴赫的 α 系数为 0.78，表明内部一致性良好。研究结果表明，HHI（11 项）中文版是评估中国癌症患儿希望的可靠有效工具。可以为该人群提供基于证据的干预措施以增强希望。
