Agreement was examined between the answers to an employment survey administered to discharged patients with spinal cord injury on two occasions 6 mo. apart. Analysis suggested reasonable test-retest reliability, with kappas ranging from .65 to .87 for the categorical data, e.g., current employment information and amount of time before respondents achieved any return to work.
对脊髓损伤出院患者进行了两次间隔6个月的就业情况调查，对两次调查的答案进行了一致性检验。分析表明重测信度合理，分类数据（如当前就业信息和受访者恢复工作前的时间）的kappa值在0.65至0.87之间。
