颅脑损伤患者生活质量量表中文版本效度和信度的初步评价

Evaluation on Validity and Reliability of Chinese Version of Quality of Life after Traumatic Brain Injury in Patients with Brain Trauma.

目的评价颅脑损伤患者生活质量量表(quality of life after traumatic injury,QOLIBRI)中文版本的效度和信度。方法选取符合纳入标准的20例患者为调查对象,用调查-再调查(test-retest)方法实施调查。通过重测信度和内部一致性Cronbach sα系数评价其信度;进行SF-36、GOSE、HADS、MMSE量表评分,通过与QOLIBRI量表相关分析考察其效度。结果量表各亚组的重测信度系数为0.915-0.995,具有稳定的重测信度。各亚组内部一致性系数(Cronbach sα)为0.505-0.965,内部一致性尚可。QOLIBRI各亚组与SF-36总分显著相关,QOLIBRI(除人际关系领域外)绝大多数亚组与GOSE相关。多数亚组与HADS相关,仅少数条目与MMSE相关。结论QOLIBRI具有较好的信度和效度。

Objective To evaluate the validity and reliability of the Chinese version of QOLIBRI （ quality of life after traumatic brain injury）. Methods The study was conducted in twenty patients with brain trauma using test-retest method and internal consistency was measured with eronbach＇s alpha coefficient. The correlation of SF-36, GOSE, HADS or MMSE with QOLIBRI＇s reliability was analyzed, respectively. Results Test-retest reliability of QOLIBRI＇s subscales was stable with scores ranging from 0. 915 to 0. 995. The Cronbach＇s alpha coefficient of subscales was passable with scores ranging from 0. 505 to 0. 965. The total score of QOLIBRI was positively correlated with SF36 score （r =0. 90,P 〈0.05）and GOSE score （ r = 0. 76, P 〈 0. 05 ） , and negatively correlated with HADS score （ r = - 0. 50, P 〈 0.05 ） , but not correlated with MMSE score （ r = 0. 24, P 〈 0. 050）. Conclusions The Chinese version of QOLIBRI has good reliability and validity as an instrument to evaluate.
