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

^aKappa values ≥0.80 were taken to represent excellent agreement, 0.60–0.79 substantial agreement and 0.40–0.59 moderate agreement
^bFor ICCs, values more than 0.75 indicated good reliability and less than 0.75 poor to moderate reliability
