中文版自我感受负担量表在癌症患者中应用的信效度评价

Reliability and validity of the Chinese version of self-perceived Burden Scale for cancer patients

目的研究中文版自我感受负担量表（self．perceived burden scale，SPBS）在癌症患者中应用的信、效度。方法翻译并形成中文版SPBS，采用专家法测量其内容效度。进行预实验，对量表的表面效度进行评价，经过研究小组反复修改和调整后，形成最终量表。对220例癌症患者进行问卷调查以评定该工具的信、效度。结果中文版SPBS共有8个条目，其Cronbach’s α系数为0．874。因子分析得出2个公因子，累计方差贡献率为61．004％。结论中文版SPBS具有良好的信、效度，适合中国文化背景下癌症患者自我感受负担的测量。

Objective To investigate the Chinese version of Self-perceived Burden Scale（SPBS） for cancer patients. Methods Established the psychometric properties of the Chinese version of SPBS, a convenience sample of 220 patients were recruited for evaluation. Results The Chinese version of SPBS comprised 8 items. Exploratory analysis showed that the most interpretable solution consisted of 2 factors. The accumulative variance contribution which explained 61.004% of variance of the total scale. Meanwhile, the Cronbach＇s α coefficient was 0.874. Conclusions It suggests that the S-item Chinese version of the SPBS has good reliability and validity,which could be used as a tool for measuring cancer patients＇ burden.
