Represents the number of interviews that were successfully recorded and, therefore, available for a second rater to verify.
Interviews with a 5 or more point difference between Rater 1 and Rater 2 on total SIGH-SAD score. The denominator for the percentages is the number of interviews with a Rater 2 from the prior column.
Interviews where Rater 1 and Rater 2 differed on whether SIGH-SAD recurrence criteria were met at a followup visit.
The absolute value of the mean difference between Rater 1 and Rater 2 in total SIGH-SAD scores for the interviews identified as discrepant based on discrepant scores and/or discrepant recurrence status.
24 subjects participated during the initial (feasibility) year, which did not include a summer followup, leaving 153 total participants eligible for summer followup.
