The objective of this study was to investigate the relationship betwee
n problem solving self-appraisal, observed behaviours in a problem sol
ving discussion, and dyadic adjustment. The sample consisted of 40 cou
ples who completed the Dyadic Adjustment Scale, the Problem Solving In
ventory and who participated in a filmed discussion. Observed behaviou
rs were coded using the Global Interaction action Coding System for Dy
adic Interactions. For both men and women, results showed significant
relations between problem solving self-appraisal components, coded beh
aviours, and marital adjustment. Problem solving self-appraisal and be
havioural activities independently accounted for observed fluctuations
in marital satisfaction. Theoretical implications of these results ar
e discussed.
