  • % agree = % raw agreement; τ = Kendall’s Tau-b coefficient (α = 0.05); p = significance (1-tailed); c = constant (no statistics were computed because rater A/B1/B2/B3 were constants); VAS = visual analog scale; — = no data.

  • Note: Rater A = author; B1 = psychiatrist; B2 = psychiatric social worker; B3 = psychiatric nurse.
