what does this mean The intraclass correlations (ICC), with 95% confidence intervals and results of statistical comparison to chance values, are reported in Table 3. The ICC for the total milestones score was 0.876 (p < 0.001), which indicates that it has good reliability as defined by Koo and Li (2016). ICCs for all of the individual milestones, except Group score, exceeded chance values at the p < 0.01 level. Figure 1 shows the percentage of ICCs that indicated poor (6.3%), moderate (56.3%), good (31.3%), and excellent (6.3%) reliability. Most indicated moderate or good reliability. The ICC for the total barriers score was 0.629 (p < 0.001), which indicates moderate reliability. ICCs for 10 of the 24 individual barriers (41.7%) exceeded chance levels at p < 0.01 level, and for 5 others (20.8%) at the p < 0.05 levels. With respect to barriers, 87.5% were of poor reliability and the rest were of moderate reliability
