Related to these findings, those husbands who reported the highest ratings of global marital satisfaction showed the highest ratings in daily intimacy. Similarly, the wives who rated their global satisfaction highest also had higher levels of daily intimacy. Greater marital satisfaction was found among those who had the higher ratings of intimacy. Further, couples with high levels of demand-withdraw communication rated their average daily intimacy as much lower. This suggests a relationship between one's overall marital satisfaction and the amount of intimacy in a relationship, though no causation can be proven with the present research. Self-esteem has also been found to be a predictor of satisfaction, with couples exhibiting both high self-esteem and high self-disclosure levels being the most satisfied in their relationships.
