数字评分法在脊髓损伤患者感觉异常关键点评分中的信度

Test-retest Reliability and Inter-rater Reliability of Numerical Rating Scale for Abnormal Sensation Points of Patients with Spinal Cord Injury

目的检验数字评分法在脊髓损伤感觉异常关键点评分中的重测信度和评测者间信度。方法2016年10月至2018年10月,采用数字评分法对69例脊髓损伤患者的感觉异常关键点进行评分。评测者A对关键点进行第一次评分,次日评测者B对同一关键点进行再次评分。3周后由评测者A再次对同一患者进行评分。结果两侧肢体针刺觉评分和轻触觉评分的重测信度(r>0.88,P<0.001)和评测者间信度(ICC>0.93,P<0.001)均良好。颈段、胸段和腰段针刺觉评分和轻触觉评分的重测信度(r>0.88,P<0.001)和评测者间信度(ICC>0.93,P<0.001)均良好。结论数字评分法在脊髓损伤患者感觉异常关键点评分中具有良好的重测信度和评测者间信度。

Objective To investigate the test-retest reliability and inter-rater reliability of Numerical Rating Scale(NRS)for abnormal sensation points of patients with spinal cord injury(SCI).Methods From October,2016 to December,2018,69 patients with SCI were enrolled.Their impaired sensory points were measured with NRS.The score of sensory points was tested by examiner A firstly,and examiner B did the same work next day.Then,the examiner A retested the same patients after three weeks.Results The Pearson correlation coefficients and intraclass correlation coefficient(ICC)of the test-retest reliability and inter-rater reliability for sensory score of both sides were all above 0.88 and 0.93 respectively(P<0.001).The Pearson correlation coefficients and ICC of the sensory score of the different injury levels were all above 0.88 and 0.93 respectively(P<0.001).Conclusion NRS has high test-retest reliability and inter-rater reliability for the assessment at abnormal sensation points of patients with SCI.
