  1. Note: * p < 0.05,** p < 0.001. ICC reliability coefficients can be interpreted as follows: <.40 are poor, .40-.59 fair, .60-.74 good and .75-1.00 excellent [47]. Cohen’s Kappa can be interpreted as follows: < 0 no agreement, .0–.20 poor, 0.21–0.40 fair, 0.41–0.60 moderate, 0.61–0.80 substantial and 0.81–1 almost perfect agreement [48]
