目的 引进并修订加拿大McMaster大学研发的青年癌症患者心理痛苦量表（Cancer Distress Scales for Adolescent and Young Adults,CDS-AYA）,并进行信效度检验。方法 成立量表汉化研究小组,遵循FACIT翻译模型进行量表的正译和回译,通过专家跨文化调适、认知访谈和预调查进行量表条目内容优化。采用便利抽样法,于2020年4月—9月对505例青年癌症患者进行调查,并选取30例患者于2周后再次测量;邀请6名专家进行内容效度评定,通过计算量表的内部一致性、结构效度、内容效度进行信效度检验。结果 修订后的中文版CDS-AYA共6个维度（癌症影响、身体、情绪、认知、癌症担忧、就业/学业）、50个条目,量表各条目专家内容效度指数为0.83~1.00。探索性因子分析显示,6个因子的累积方差贡献率为70.079%;验证性因子分析显示, χ²/df=2.886,GFI=0.656,AGFI=0.624,CFI=0.809,NFI=0.736,IFI=0.810,TLI=0.800。量表的总Cronbach’s α系数为0.971,各维度的Cronbach’s α系数为0.892~0.962,重测信度为0.963。结论 中文版CDS-AYA具有良好的信效度,模拟拟合度较好,可用于我国青年癌症患者心理痛苦的筛查和评估。

Objective To translate the Cancer Distress Scales for Adolescent and Young Adults（CDS-AYA）,developed by McMaster University,Canada,and to test its reliability and validity. Methods A research group was established for the instrument translation and psychometric properties evaluation. The forward translation and back translation of the scale were carried out following the FACIT translation model. Final contents of the scale were established through culture adaption,cognitive interviews and pilot survey. To examine the validity and reliability of the instrument,a total of 505 young cancer patients recruited by convenience sampling were surveyed from April to September 2020. Among them,30 patients were selected to complete the instrument 2 weeks later. Six experts were invited to evaluate the content validity. The psychometric properties of the instrument was evaluated by calculating the internal consistency,structure validity,and content validity. Results The revised Chinese version of CDS-AYA has 6 dimensions（cancer impact,body,emotion,cognition,cancer concern,employment/academic） and 50 items. The content validity index of each item ranged from 0.83 to 1.00. Exploratory factor analysis showed that the cumulative variance contribution rate of the 6 factors was 70.079%. Confirmatory factor analysis supported the measurement model with χ²/df=2.886,GFI=0.656,AGFI=0.624,CFI=0.809,NFI=0.736,IFI=0.810,TLI=0.800. The Cronbach’s α of the scale was 0.971 and ranged from 0.892 to 0.962 for the 6 subscales. The test-retest reliability was 0.963. Conclusion The Chinese version of CDS-AYA has good reliability and validity. The model fit is good,and can be used to screen and assess psychological distress in young cancer patients in China.
