Linking questionnaire reports and observer ratings of young couples' hostility and support.

Past studies have correlated observer ratings with questionnaire self- and partner-reports of behaviors in close relationships. However, few studies have actually proposed and tested longitudinal models that link observer ratings to past behaviors and to questionnaire self- and partner-reports of behaviors during an observational task. Using data from a panel of 324 young couples, we demonstrate that (a) observer ratings of hostility and support are significantly related to couple reports of the same behavior in the relationship two years earlier, and (b) respondent and partner questionnaire reports of hostility and support during the observational task converge with observer ratings of the same behavior even after controlling for earlier self- and partner-reports. These findings demonstrate that observer reports based on brief discussion tasks reflect the tenor of the relationship over a relatively long period of time. They also demonstrate that couple reports of interactions reflect observable behaviors beyond that attributed to earlier self- and partner-reports. Consistent with previous research, effect sizes are larger for hostility than support but there are few differences between men and women.
