PROMIS 1 Wave 2 Pain

The pain subsample of the PROMIS 1 Wave 2 Pain and Depression study was developed to test the utility of computer adaptive tests (CATs) with individuals diagnosed with back and leg pain. Patients were recruited and treated with epidural steroid injections. This protocol was aimed at comparing the psychometric properties of the PROMIS item banks with non­-PROMIS ‘gold standard’ instruments, diagnostic data, and medical records.本PROMIS（Patient-Reported Outcomes Measurement Information System，患者报告结局测量信息系统）1 Wave 2疼痛与抑郁研究的疼痛亚样本，旨在针对确诊为腰腿痛的人群，验证计算机自适应测试（Computer Adaptive Tests，CATs）的应用价值。研究招募了相关患者，并为其实施硬膜外类固醇注射治疗。本研究方案旨在对比PROMIS项目库与非PROMIS"金标准"测评工具、诊断数据及医疗记录的心理测量学特性。
