To translate Female Self-Advocacy in Cancer Survivorship (FSACS) scale and evaluate the psychometric properties of Chinese version of FSACS scale among female cancer survivors in China.
This study employed a cross-sectional design. FSACS scale was forward-backward translated and cognitive interviews were conducted for cultural adaptation. The newly translated tool was distributed to female cancer survivors to test psychometric properties, including item analysis, content validity, construct validity, criterion validity, internal consistency, and test-retest reliability.
A total of 436 female cancer survivors were recruited in a Chinese tertiary cancer center from May to August in 2021. Item analysis showed statistical significance ( < 0.05) for each one and no ceiling or floor effect. The item-level content validity index ranged from 0.86 to 1.00 and the scale-level content validity index was 0.98. Three factors were extracted based on parallel analysis, and confirmatory factor analysis proved a good model fit with the original 3-factor structure. Pearson's correlation coefficient showed acceptable criterion validity. The Cronbach's α of 0.880 demonstrated the scale's internal consistency reliability, and the Alpha coefficients were 0.826, 0.763, and 0.859 for its three dimensions, respectively. The interclass correlation coefficients for test-retest reliability was 0.904 (0.870-0.891, < 0.01) which confirmed the external reliability of the scale.
The Chinese version of FSACS scale proved to be a valid and reliable instrument that can be applied among Chinese female cancer survivors. Further research could be conducted in larger populations or people in different cancer stages.
翻译癌症幸存者女性自我倡导（FSACS）量表，并评估中文版FSACS量表在中国女性癌症幸存者中的心理测量学特性。
本研究采用横断面设计。对FSACS量表进行前后向翻译，并通过认知访谈进行文化调适。将新翻译的工具分发给女性癌症幸存者以测试其心理测量学特性，包括项目分析、内容效度、结构效度、效标效度、内部一致性和重测信度。
2021年5月至8月，在中国一家三级癌症中心共招募了436名女性癌症幸存者。项目分析显示每个项目均具有统计学意义（<0.05），且无天花板效应或地板效应。项目水平的内容效度指数范围为0.86至1.00，量表水平的内容效度指数为0.98。基于平行分析提取了三个因素，验证性因素分析证明该模型与原始的三因素结构拟合良好。Pearson相关系数显示效标效度可接受。Cronbach's α为0.880，表明量表具有内部一致性信度，其三个维度的Alpha系数分别为0.826、0.763和0.859。重测信度的组内相关系数为0.904（0.870 - 0.891，<0.01），证实了量表的外部信度。
中文版FSACS量表被证明是一种有效且可靠的工具，可应用于中国女性癌症幸存者。可在更大规模人群或不同癌症阶段的人群中开展进一步研究。
