This research examined the relations among various distal variables and interactive behavior and on-line cognition in a complete longitudinal design over 1 year. Fifty-seven married couples had problem-solving discussions that were videotaped. Interactive behavior was coded by observers, and on-line cognitions were assessed using a tape-review procedure (see Fletcher & Fitness, 1990). As predicted, the association between relationship satisfaction and both interactive behavior and on-line cognition was generally mediated by negative attributions to the partner; however, depression obtained direct unmediated paths to interactive behavior and on-line cognition. Cross-lagged analyses suggested that the causal links between distal variables and problem-solving interactive behaviors and on-line cognition tend to go in both directions over time. Implications are discussed.
