The extent to which different measures of back pain impact represent an underlying common factor has implications for decisions about which one to use in studies of pain management and estimating one score from others.
To determine if different self-report back pain impact measures represent an underlying pain latent variable and estimate associations with it.
Seven pain impact measures completed by Amazon Mechanical Turk adults are used to estimate internal consistency reliability and associations: Oswestry Disability Index (ODI), Roland-Morris Disability Questionnaire (RMDQ), short form of the Örebro Musculoskeletal Pain Questionnaire (OMPQ), Subgroups for Targeted Treatment (STarT) Back Tool, the Graded Chronic Pain Scale (GCPS) disability score, PEG (Pain intensity, interference with Enjoyment of life, interference with General activity), and Impact Stratification Score (ISS).
The sample of 1,874 adults with back pain had an average age of 41 and 52% were female. Sixteen percent were Hispanic, 7% non-Hispanic Black, 5% non-Hispanic Asian, and 71% non-Hispanic White. Internal consistency reliability estimates ranged from 0.710 (OMPQ) to 0.923 (GCPS). Correlations among the measures ranged from 0.609 (RMDQ with OMPQ) to 0.812 (PEG with GCPS). Standardized factor loadings on the pain latent variable ranged from 0.782 (RMDQ) to 0.870 (ISS).
Scores of each measure can be estimated from the others for use in research.
不同腰痛影响测量指标的程度是否代表潜在的共同因素，这对疼痛管理研究中使用哪种指标以及从其他指标估计一种指标的分数有影响。
确定不同的自我报告腰痛影响测量指标是否代表潜在的疼痛潜变量，并估计与该潜变量的关联。
使用亚马逊土耳其机器人（Mechanical Turk）的 7 种疼痛影响测量指标来估计内部一致性信度和关联：Oswestry 残疾指数（ODI）、Roland-Morris 残疾问卷（RMDQ）、Örebro 肌肉骨骼疼痛问卷（OMPQ）简短版、靶向治疗分组工具（STarT）、Graded Chronic Pain Scale（GCPS）残疾评分、PEG（疼痛强度、对生活享受的干扰、对一般活动的干扰）和影响分层评分（ISS）。
共有 1874 名腰痛的成年人参与了该研究，平均年龄为 41 岁，52%为女性。16%为西班牙裔，7%为非西班牙裔黑人，5%为非西班牙裔亚洲人，71%为非西班牙裔白人。内部一致性信度估计值范围为 0.710（OMPQ）至 0.923（GCPS）。各指标之间的相关性范围为 0.609（RMDQ 与 OMPQ）至 0.812（PEG 与 GCPS）。疼痛潜在变量的标准化因子负荷值范围为 0.782（RMDQ）至 0.870（ISS）。
可以从其他指标估计每个指标的分数，以便在研究中使用。
