From: Validation study of the Polish version of the Evidence-Based Practice Profile Questionnaire

Domain Range of weighted kappas for items in each domaina Range of ICCs for items in each domainb Domain ICCs Mean difference 0.95 CI for mean difference P-value^
I. Relevance 0.35–0.74 0.62–0.89 0.94 0.42 −1.90–1.06 0.577
II. Sympathy 0.22–0.52 0.22–0.67 0.68 0.37 −1.24–0.50 0.405

V. Confidence 0.25–0.70 0.52–0.85 0.95 0.78 −1.77–0.22 0.125
  1. aKappa values ≥0.80 were taken to represent excellent agreement, 0.60–0.79 substantial agreement and 0.40–0.59 moderate agreement
  2. bFor ICCs, values more than 0.75 indicated good reliability and less than 0.75 poor to moderate reliability
