The study explored spousal accuracy and positive marital behavior (PMB) and negative marital behavior (NMB) areas&rsquo / three different evaluations which were frequency, emotional impact and attributed importance in distressed and nondistressed couples. Participants of the study were 81 married couples. All 162 spouses filled out Positive and Negative Affect Schedule (PANAS), Dyadic Adjustment Scale (DAS), Communication Skills Inventory and Information Form. Additionally one spouse in each couple filled out Spouse Observation Checklist (SOC) Form A whereas the other spouse filled out SOC Form B. Spousal accuracy were assessed by partial pairwise intraclass correlation. R-to-z transformation was used to find on which PMB and NMB areas&rsquo / accuracy distressed and nondistressed couples differ. Six Repeated Measures MANOVAs were conducted to explore differences in distressed and nondistressed couples / wives and husbands / self-report and spouse-report in three evaluations of PMB and NMB. In order to find most important PMB and NMB areas&rsquo / frequencies in terms of their relationship with marital adjustment, two Roy-Bargmann Stepdown Analysis were conducted by controlling for positive affect, negative affect and communication skills. Principal component analysis was employed to the self and spouse reports of marital behavior areas&rsquo / frequencies and then two stepwise multiple regression analyses were used to identify which factors of marital behavior play a significant role in predicting marital adjustment. Results revealed that nondistressed spouses were more accurate in predicting their partners&rsquo / reports of emotional impact and attributed importance / more frequently engaging in PMB, less frequently engaging in NMB, feel more positive about and attribute more importance to PMB compared to distressed spouses. Spouse report of marital behavior explained more variance than self report of marital behavior / NMB and affectional marital behavior explained more variance than PMB in marital adjustment.
