Intercoder agreement. A team of four coders were trained to
use the IDCS. An independent team (relative to the IDCS) of six
coders was trained to use the SCIS. The two support discussions
for a couple were coded by different coders. Intercoder agreement
for the SCIS dimensions was assessed weekly with intraclass
correlations between coders’ ratings of a randomly selected set of
20% of the interactions. Observers were blind to the reliability
checks. Intercoders’ agreement ranged from .62 to .87 for the
IDCS dimensions and from .74 to .89 for the SCIS.
