"The present study examined the association between personality similarity and life satisfaction in a large, nationally representative sample of 1,608 romantic couples. Similarity effects were computed for the Big Five personality traits as well as for personality profiles with global and differentiated indices of similarity. Results showed substantial actor and partner effects, indicating that both partners' personality traits were related to both partners' life satisfaction. Personality similarity, however, was not related to either partner's life satisfaction. We emphasize the importance of thoroughly controlling for each partner's personality and for applying appropriate analytical methods for dyadic data when assessing the effect of personality similarity in couples."

"However, as far as personality similarity in romantic couples is concerned, the everlasting question about who is a person's perfect match has not yet been answered satisfactorily. Is having a partner whose personality is similar to one's own associated with higher levels of satisfaction? Or do we prefer someone rather dissimilar?"
.............
"Global profile similarity is calculated using Intraclass Correlation Coefficient.
Shape similarity is calculated by correlating the scores in one partner's profile with the scores of the other partner's profile using Pearson correlations.
Elevation similarity is measured using difference scores (i.e., absolute value of difference between the overall mean across traits: mean similarity).
Scatter similarity is also computed using difference scores (i.e., absolute value of difference between the variances across all traits within the profiles: variance similarity)."
[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. ]

"Participants: total sample size of 1,608 couples (Nind = 3,216). Men were on average 51.88 years old (SD = 13.58), women 49.10 years (SD = 13.35). The mean length of the relationship was 24.21 years (SD = 14.11) and the majority of couples were married (85%).
Personality was assessed using a German 10-item instrument derived from the Big Five Inventory. For each trait, participants reported the extent to which each of the two statements per personality trait described themselves on an 11-point scale ranging from 0 (completely disagree) to 10 (completely agree). Correlations between the two items for Extraversion, Agreeableness, Conscientiousness, Emotional Stability, and Openness were .39, .11, .24, .40, and .21, respectively." THAT IS WHY THE PAPER IS FLAWED, BIASED.
The paper "Only the congruent survive - Personality similarities in couples. Personality and Individual Differences" Rammstedt & Schupp (2008), was not EVEN cited.
Also the papers written by Dr. Pieternel Dijkstra, not EVEN cited.
"Our findings may help understand why so many relationships end in divorce due to mismatches in personality."
"Discussion
Our findings strongly support the 'similarity-attraction' hypothesis: Individuals clearly desire a potential partner with a similar personality. In addition to finding a mate with a similar personality, our study showed that individuals seek a mate who is slightly 'better' than they are: They prefer a mate who is somewhat less neurotic, more agreeable, more conscientious, more open and more extraverted than they are themselves.
.... mismatches in personality are a frequently mentioned cause for relationship break-up. If former partners indeed have dissimilar personalities, our findings underline how difficult it is for many people to select a mate with a similar personality, or, alternatively, how little value individuals put on finding a similar partner in terms of personality.
The present study's results, as well as the results found in previous studies (e.g., Eastwick & Finkel, 2008), may be used to educate people, especially singles, about what really matters in long-term relationships, for instance, similarity in personality, instead of complementarity."

Next post will be about the NEW PAPER "Partnership longevity and personality congruence in couples" Rammstedt, Schupp et al. (2013)
Please read also:
"Stability and change of personality across the life course"
and
"personality traits are highly stable"
Remember:
Personality traits are highly stable in persons over 25 years old to 45 years old (the group of persons who could be most interested in serious online dating) They have only minor changes in personality (less than 1 interval in a normative test) and the 16PF5 test will not "see" them because the output of the 16PF5 test are 16 variables STens (Standard Tens) taking integer values from 1 to 10. STens divide the score scale into ten units. STens have the advantage that they enable results to be thought of in terms of bands of scores, rather than absolute raw scores. These bands are narrow enough to distinguish statistically significant differences between candidates, but wide enough not to over emphasize minor differences between candidates.
The 3 milestone discoveries of the 2001 - 2010 decade for Theories of Romantic Relationships Development are:
I) Several studies showing 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"
II) People often report partner preferences that are not compatible with their choices in real life. (Behavioural recommender systems or other system that learns your preferences are useless)
III) What is important in attracting people to one another may not be important in making couples happy. Compatibility is all about a high level on personality similarity between prospective mates for long term mating with commitment.
Also there is a similarity trilogy between genetic, mate choice and personality based recommender systems.
WorldWide, there are over 5,000 -five thousand- online dating sites
but no one is using the 16PF5 (or similar) to assess personality of its members!
but no one calculates similarity with a quantized pattern comparison method!
but no one can show Compatibility Distribution Curves to each and every of its members!
but no one is scientifically proven!
The only way to revolutionize the Online Dating Industry is using the 16PF5 normative personality test, available in different languages to assess personality of members, or a proprietary test with exactly the same traits of the 16PF5 and expressing compatibility with eight decimals (needs a quantized pattern comparison method, part of pattern recognition by cross-correlation, to calculate similarity between prospective mates.)
High precision in matching algorithms is precisely the key to open the door and leave the infancy of compatibility testing.
It is all about achieving the eighth decimal!
With 8 decimals, you have more precision than any person could achieve by searching on one's own, but the only way to achieve the eighth decimal is using analysis and correlation with quantized patterns.
Without offering the NORMATIVE16PF5 (or similar test measuring exactly the 16 personality factors) for serious dating, it will be impossible to innovate and revolutionize the Online Dating Industry
All other proposals are NOISE and perform as placebo.
