This article reports a test of a longitudinal model linking interpersonal c
onflict communication and relationship quality. The model stresses episodic
factors that function to mediate the conflict-relationship link. In partic
ular the competence-based model specifies that assessments of competence an
d one's own communication satisfaction filter the effects of conflict on re
lational quality when measured concurrently at Time 1 (T1). In addition, th
e competence-based model includes the hypothesized impact of relational fea
tures at T1 on conflict strategies weeks later at Time 2 (T2) which indicat
es a reciprocal causal connection between message behavior and relational f
eatures. Structural equation modeling analyses support the mediational role
of episodic assessments, which constitutes the heart of the model. However
, relational quality at T1 did not predict conflict behavior at T2. Instead
, analyses revealed that conflict behavior at T1 and partner conflict at T2
predict conflict behavior at T2.
