In a study by Laurenceau and colleagues, several differences were found in the satisfaction of spouses based on their daily-diary recordings of self-disclosures in their daily interactions. The results show that the actual disclosures in the process of self-disclosure may not be the only factors that facilitate intimacy in relationships. Husbands' intimacy was most strongly predicted by self-disclosure, while perceived responsiveness to disclosure was the stronger predictor for wives' feelings of intimacy with their husbands. A different study found evidence of wives' perceptions of their husbands' self-disclosures as being a strong predictor of how long a couple will stay together. Those who think their husbands are not sharing enough are likely to break up sooner. This finding links to the idea of positive illusions in relationship studies. For husbands, the actual act of self-disclosure is more indicative of their feelings of intimacy with their wives. On the other hand, wives are thought to value more the feelings of being understood and validated by their husbands' responsiveness to their disclosures, and this is the more important factor in their feelings of intimacy in their marriages.
