中文版肿瘤患者食欲症状问卷信度、效度分析

Reliability and Validity Research of Chinese Version of Cancer Appetite and Symptom Questionnaire

摘要

摘要:
目的对中文版肿瘤患者食欲症状问卷（CASQ）的信度和效度进行研究。方法翻译、回译形成CASQ中文问卷，对88例肿瘤患者使用CASQ进行问卷调查，并对中文版CASQ进行条目区分度检验，同时采用PG-SGA评估纳入研究对象的营养风险，将PG-SGA与CASQ比较并进行效度检验。在第一次测量之后，间隔7天进行第二次测量，并同时对前后两次的CASQ进行信度研究。
结果 CASQ各条目得分与问卷总分的相关系数在0.242~0.653之间，差异有统计学意义（P < 0.05），重测信度系数结果表明数据行为良好，分半信度结果为0.560，内部一致性信度系数为0.436，中文版CASQ总分与PG-SGA总分的r_s值为-0.475。
结论中文版的肿瘤患者食欲症状问卷具有较好的信度和效度。

Abstract:
Objective To investigate the reliability and validity of the Chinese version of cancer appetite and symptom questionnaire(CASQ).
Methods CASQ Chinese questionnaire was formed using translation and back-translation, and performed on 88 cancer patients. The entry distinction of the Chinese version of CASQ was tested. Simultaneously, PG-SGA was used to assess nutritional risks of the subjects; and it was compared with CASQ as well as the validity was tested. After the first measurement, the second measurement was made 7 days later; the reliability study of both CASQ was conducted.
Results The correlation coefficient between each entry score of CASQ and the total score of the questionnaire was 0.242-0.653(P < 0.05). The result of re-test reliability coefficient showed the data were good, the result of half-reliability was 0.560, internal consistency reliability coefficient was 0.436, and the r_s value of the Chinese version of CASQ total score and the PG-SGA total score was -0.475.
Conclusion The Chinese version of CASQ is tested to be with good reliability and validity.
