Testing of κ only signifies that the level of inter rater reliability differs from what would occur by chance (κ=0). Thus, p-values are not noted for κ results. #: n=226. : n=40. +: based on small counts for one of the two possible categories of inter rater reliability, with two or fewer children in the smaller category.
