Factor structure, Psychometric Properties and Measurement Invariance of
Faktorenstruktur, psychometrische Eigenschaften und Messinvarianz der deutschsprachigen Version des 60-Item HEXACO Persönlichkeitsinventars
Abstract. Recent lexical studies across several languages have provided evidence for six factors describing the structure of personality: the HEXACO model of personality. The present study examined the psychometric properties of the German-language version of the 60-item HEXACO Personality Inventory. The purported factor structure was confirmed using a large sample of N=3240 participants. The emerged factors showed satisfactory internal consistencies and were virtually uncorrelated. Moreover, measurement invariance across gender was established. A second study (N=853) showed that the 60-item HEXACO provides a close proxy to the 96-item version. In a third study (N=235), the HEXACO-60 exhibited a meaningful pattern of correlations to the Big-Five factors. Finally, a fourth study (N=31) provided evidence for high 7-month re-test reliability. The German-language version of the HEXACO-60 can thus be regarded as a sound tool for a reliable, valid, and relatively economical assessment of the HEXACO model.
Academics had begun to publish Scientific Research using the HEXACO model of personality and they plan to discontinue the Big Five model (a.k.a. Big 5, OCEAN or FFI five factor inventory, FFM five factor model) soon. Online dating sites using the Big Five model could be considered obsolete sites, because the Big Five model has been proven as "an incorrect and incomplete model of personality"
As some of the subdomains of the main domains of the HEXACO model are different from the subdomains of the main domains of the Big Five model, it can not be simple added the scale of the Honesty-Humility factor to the Big Five model to upgrade the personality test to the HEXACO model.
".. the Big Five's Agreeableness and HEXACO's Agreeableness are not identical. The Big Five factors do not include an Honesty-Humility factor, but some of the characteristics belonging to Honesty-Humility are incorporated into the Big Five's Agreeableness factor. Although earlier investigations found only the Big Five factors, more recent studies conducted in various languages (including English) with larger sets of adjectives recovered six factors. "
Many C-level executives (Management Teams of several online dating sites) are cooking barbecues under the water (selling smoke) and not paying attention to latest research from Academics which could be beneficial for the Online Dating Industry.
I think, legally, online dating sites using the Big Five model of personality could be considered a FRAUD because they are using an incomplete model of personality. They are assessing 5 scales and not 6 scales.
Personality Based Recommender Systems are the next generation of recommender systems because they perform far better than Behavioural ones (past actions and pattern of personal preferences)
That is the only way to improve recommender systems, to include the personality traits of their users. They need to calculate personality similarity between users but there are different formulas to calculate similarity. Recommender systems are morphing to .......... compatibility matching engines, as the same used in the Online Dating Industry since years, with low success rates until now because they mostly use the Big Five to assess personality and the Pearson correlation coefficient to calculate similarity.
The Big Five (Big 5, FFI, FFM, OCEAN model) normative personality test is obsolete. The HEXACO (a.k.a. Big Six) is another oversimplification. Online Dating sites have very big databases, in the range of 20,000,000 (twenty million) profiles, so the Big Five model or the HEXACO model are not enough for predictive purposes. That is why I suggest the 16PF5 test instead and another method to calculate similarity. 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".
[Also some Psychologists began to encourage the use of other tests for the Online Dating Industry, like:
California Psychological Inventory (CPI)
The Millon Index of Personality Styles-Revised (MIPS Revised)
but my best recommendation is, of course, the 16PF5 normative personality test.
Nor the CPI nor the MIPS can outperform the 16PF5.
The Online Dating Industry does not need a 10% improvement, a 50% improvement or a 100% improvement. It does need "a 100 times better improvement", not 100% better, 100X better]
If you want to be first in the "personalization arena" == Personality Based Recommender Systems, you should understand the ............ Online Dating Industry first of all!
What comes after the Social Networking wave?
The Next Big Investment Opportunity on the Internet will be .... Personalization!
Personality Based Recommender Systems and Strict Personality Based Compatibility Matching Engines for serious Online Dating with the normative 16PF5 personality test.
