Table 3 Test-retest reproducibility results for the Symptom Severity Scale and the Dutch-AIMS2-HFF

From: Reproducibility and responsiveness of the Symptom Severity Scale and the hand and finger function subscale of the Dutch arthritis impact measurement scales (Dutch-AIMS2-HFF) in primary care patients with wrist or hand problems

  N Mean baseline (SD) Mean 10 days (SD) Δ Mean (SD) Limits of agreement ICCagreement (95% CI) SEM SDCind SDCgroup
Symptom Severity Scale* (1–5) 84 2.09 (0.57) 1.98 (0.69) 0.11 (0.50) -0.87 to 1.09 0.68 (0.54 to 0.78) 0.36 1.00 0.11

  1. * higher score means worse functioning; SD = standard deviation; ICCagreement = intra-class correlation coefficient for agreement; CI = confidence interval; SEM = standard error of measurement; SDCind = smallest detectable change at individual level; SDCgroup = smallest detectable change at group level.
