Marriage duration, marital adjustment and psychological symptoms: a cross-sectional study.

One hundred and nine couples completed questionnaire measures of psychological symptoms, personality, and marital adjustment. They were divided into groups of short, intermediate, and long marriage duration. Psychological symptoms and marital adjustment remained fairly stable over time, although wives scored significantly worse than husbands on most measures in the intermediate duration group. In the short marriages, half the variance in marital satisfaction was predicted by the partner's marital questionnaire score, but when this variable was eliminated from the regression equation, psychological symptoms (phobic anxiety in wives and depression in husbands) were the main predictors of marital satisfaction. In the intermediate group, hostility levels were the main predictors of marital satisfaction. In the long marriages, marital satisfaction was predicted mainly by personality factors (assertiveness in husbands and personal flexibility in wives) and by levels of generalized anxiety. The findings suggest that couples who constructively resolve difficulties in expressing hostility within marriage are more likely to remain married than those who fail to do so.
