Note. % Base Rate = % of reports with variable present after 3rd rater clarified any disagreements between the first two raters. All
other columns report reliability data from the first two independent raters. % Both Present = % of protocols in which both raters rated
the variable as present. % Both Absent = % of protocols in which both raters rated the variable as absent. % Disagree = % of protocols
with a disagreement between raters. % Agree = % of protocols in which both raters agreed. CI = Confidence Interval. Landis and
Koch (1977) indicated that Kappa coefficients of .61–.80 indicate “substantial” agreement and from .81–1.00 indicate “almost perfect”
agreement.
