Innovations: to take the 16PF5 test 3 times

In previous posts I had written that Innovations the Online Dating Industry needs will come from latest discoveries in theories of romantic relationships development with commitment (personality similarity between prospective mates).

WorldWide, there are over 5,000 online dating sites
but no one is using the 16PF5 to assess personality of its members.
Without acquiring the license to offer the 16PF5 for serious dating, it will be impossible to innovate and revolutionize the Online Dating Industry.

In compatibility matching methods there are 2 steps:
1) to objectively measure personality traits or other human variables.
2) to calculate compatibility between prospective mates.

LIFEPROJECT METHOD is not intended for newbies in the Online Dating arena.
It is intended for past and actual dissatisfied customers of eHarmony , Match/Chemistry, PerfectMatch, Be2, Parship and others.
It is intended for persons who had been hurted in their feelings by members of those sites
It is intended for over 26 years old normal persons.

The 16PF5 test is not more complex than the one used by eHarmony , Match/Chemistry, PerfectMatch, Be2, Parship and others.

(the IPAT Institute for Personality and Ability Testing, Inc. is the owner)
The 16PF Questionnaire is a quantifiable, well-documented 185 items instrument for measuring the 16 normal personality dimensions.

Time: computer administration, less than 30 minutes. [perhaps faster than eHarmony's and Chemistry's]
Reliability: Internal consistency averages .76. Test/retest reliabilities average .80 for two-week interval, and .70 for two-month interval. [far better than any others, which are less than .60]
Validity: Validity studies presented in the 16PF Fifth Edition Technical Manual provide considerable evidence of the construct validity of the primary and global scales.

The following languages are available for the 16PF Questionnaire
Chinese (traditional)
English (United Kingdom)
English (United States)
Portuguese (Brazilian)
Portuguese (European)
Spanish (European)
Tagalog (Philippines)
(Normative tests can not simply be translated, because you need the norm for that test, and that norm is actualized each and every time Census Figures are released)

I think women will love a rational explanation of why they need to take the test 3 times, with these 2 fresh papers

1) "Human oestrus" Gangestad & Thornhill (2008)
explains that "Only short-term but not long-term partner preferences tend to vary with the menstrual cycle"

2) "Does the contraceptive pill alter mate choice in humans?" Alvergne & Lummaa (2009)
If you carefully read that milestone paper you will discover that although men do not take contraceptive pills, they detect women who do not take and women who take those pills or other hormonal contraceptive methods. "revisiting the lap-dancing study, normally cycling lap dancers made nearly USD20 more per hour in their fertile phase as compared to their luteal phase, whereas pill users did not show any mid-cycle peak in tip earnings"

"Effects of ovulatory-cycle phase on lapdancer tip earnings per shift in normally cycling women versus women using hormonal contraception (pill users). Over a 60-day period, 18 heterosexual women working as lap-dancers reported day-by-day start or stop of menstruation and their tip earnings from any shift they worked. Normally cycling participants earned nearly USD335 per 5-hr shift during oestrus, USD260 per shift during the luteal phase, and USD185 during menstruation. By contrast, pill users showed no rise in earnings during oestrus, suggesting that the use of pill interrupts cycling attractiveness of women to men. Error bars represent 95% confidence intervals." Figure 1 in paper

A Marketing campaign should be incisive in this new discovery:
contraceptive hormonal methods alter mate choice in humans because only short-term but not long-term partner preferences tend to vary with the menstrual cycle.
For each persons "internal compatibility" will be calculated between #1_try and #2_try, and between #2_try and #3_try. If "internal compatibility" between #2_try and #3_try is equal or slightly higher than "internal compatibility" between #1_try and #2_try, then #3_try is the one pattern to be added to the database.

I think lots of persons could be interested in meeting/contacting other persons sharing nearly the same personality because they will be *predictable* for them.
a note about IRT and the 16PF5:
IRT models have been applied to the 16PF and several papers and conference presentations have described those efforts.
