PAPER: Personality perceptions and relationship satisfaction in couples

 http://www.sciencedirect.com/science/article/pii/S0092656614000178
The present study investigates how perceptions of personality are related to relationship satisfaction in an age-heterogeneous sample of romantic couples. Self- and partner-perceptions as well as perceived similarity and self-other agreement were examined separately for the Big Five personality traits. Results of Actor–Partner-Interdependence Models (APIM) revealed substantial effects of partner-perceived personality in all Big Five traits on both partners’ relationship satisfaction. In contrast, effects of self-perceived personality on relationship satisfaction were small. Over and above self- and partner-rated personality, perceiving one’s partner as similar to oneself made a small unique contribution to relationship satisfaction in couples. These results emphasize the importance of integrating self- and partner-perceptions of personality for relationships outcomes.

For online dating applications and personality based recommenders the above paper is not useful because daters are "distinguishable" instead of "exchangeable".

Please remember: Big Five normative test had been proven/revealed as an incomplete and incorrect model to assess/measure personality of persons. Now replaced by HEXACO or Big Six test.

Similarity is a word that has different meanings for different persons or companies, it exactly depends on how mathematically is defined. I calculate similarity in personality patterns with (a proprietary) pattern recognition by correlation method. It takes into account the score and the trend to score of any pattern. Also it takes into account women under hormonal treatment because several studies showed contraceptive pills users make different mate choices, on average, compared to non-users. "Only short-term but not long-term partner preferences tend to vary with the menstrual cycle".
