Abstract

Objective To present briefly introductions and evaluations on the constructs, psychometric properties (reliability, validity, reactivity etc.) and applications of the system of Quality of Life Instruments for Cancer Patients QLICP(V1.0) including 12 kinds of scales for patients with head and neck cancer, brain cancer, lung cancer, breast cancer, esophageal cancer, gastric cancer, colorectal cancer, liver cancer, cervical cancer, ovarian cancer, leukemia and lymphoma. Methods Based on our measuring data from relevant patients at hospitals, the constructs, characteristics and psychometrics of the system above were analyzed and presented. Internal consistency reliability for each domain and the overall scale was assessed using Cronbach's alpha coefficient, and test-retest reliability through calculating the Pearson correlation coefficient between the first and second assessments. The criterion-related validity was evaluated by correlating corresponding domains of two instruments. Responsiveness was assessed through comparing the mean difference between the pre-treatment and post-treatments with standardized response mean (SRM). The use agreements and literature reviews of this system were used to understand the applications of 12 kinds measurement scales. Results The quality of life scales for 12 kinds of cancer patients of the system QLICP(V1.0) have good construct( 5 domains, 11-15 facets), reliability, validity and a certain degree of responsiveness. The internal consistency reliability Cronbach's α coefficients for the overall scale of QLICP in different cancers was from 0.67 to 0.92, and the test-retest reliability (correlation coefficient) was from 0.61 to 0.99. The criterion-related validity (correlation coefficient) was for the overall scale of QLICP in different cancers was from 0.28 to 0.89, and the responsiveness SRM was from 0.25 to 1.28. And also they were widely used in clinical practice and relevant studies for the corresponding cancers. Conclusion The system QLICP(V1.0) is of outstanding characteristics with all psychometrics meeting requirements and better construct (clear hierarchical structure with items→ facets→ domains→ overall ), and can be used widely in clinical practice further.

癌症患者生活质量仪器系统的心理测量特性及其应用

目的简要介绍和评价癌症患者生活质量量表QLICP（V1.0）系统的结构、心理测量特性（信度、有效性、反应性等）及其应用，包括12种癌症、癌症、癌症、癌症、，结直肠癌癌症、癌症、癌症、卵巢癌症、白血病和淋巴瘤。方法根据医院相关患者的测量数据，分析并提出了该系统的结构、特点和心理测量方法。使用Cronbachα系数评估每个领域和整体量表的内部一致性可靠性，并通过计算第一次和第二次评估之间的Pearson相关系数来评估重测可靠性。通过关联两个工具的相应领域来评估标准相关的有效性。通过将治疗前和治疗后的平均差异与标准化反应平均值（SRM）进行比较来评估反应性。利用该系统的使用协议和文献综述，了解12种量表的应用情况。结果QLICP系统的12种癌症患者生活质量量表（V1.0）具有良好的结构（5个领域，11-15个方面）、可靠性、有效性和一定程度的反应性。不同癌症QLICP总体量表的内部一致性信度Cronbachα系数为0.67至0.92，重测信度（相关系数）为0.61至0.99。不同癌症QLICP总体量表的标准相关有效性（相关系数）为0.28至0.89，响应性SRM为0.25至1.28。它们也被广泛应用于临床实践和相应癌症的相关研究中。结论QLICP系统（V1.0）具有突出的特点，各项心理测量指标均满足要求，结构清晰（项目层次结构清晰）→ 刻面→ 域→ 总体上）并且可以在临床实践中进一步广泛使用。关键词：生活质量；癌症；仪表系统

期刊介绍： "Chinese Journal of Behavioral Medicine and Brain Science" (CN 37-1468/R, ISSN 1674-6554) is a national academic journal under the supervision of the National Health Commission, sponsored by the Chinese Medical Association and Jining Medical College. The journal was founded in June 1992 and was formerly known as "Chinese Journal of Behavioral Medicine" (1992-1993) and "Chinese Behavioral Medical Science" (1994-2008). In 2009, it was renamed "Chinese Journal of Behavioral Medicine and Brain Science" with the approval of the State Administration of Press, Publication, Radio, Film and Television. The purpose of "Chinese Journal of Behavioral Medicine and Brain Science" is to implement the health and health policies of the Party and the State, implement the principle of combining theory with practice and popularization and improvement, and reflect the major progress in the theory and practical application of behavioral medicine and brain science in my country. It publishes academic papers and scientific research results in the field of behavioral medicine and brain science in my country, and has columns such as monographs/reviews, basic research, clinical research, health prevention, methods and techniques, psychological behavior and evaluation, and systematic evaluation.
