Compatibility researcher challenges online dating sites to participate in university monitored compatibility test validity study. Researcher demands minimum standards be set for online dating compatibility tests.

"We are issuing a challenge to all other online dating sites to go head to head in a university monitored research project to compare the validity of our compatibility test to that of their compatibility tests," asserted J. Donald Lawson, Ph.D., CEO of Compatibility Researchers, L.L.C., owner of

Doctor Lawson has been a strong advocate for setting minimum standards for the assessment of psychological compatibility between couples. Standards he has advocated for include operationally defining compatibility by correlating compatibility tests with an accurate test of relationship satisfaction, and specifying that when the correlation is squared, the variance accounted for must be at least twenty percent of the total variance between the two tests.

"Even if a compatibility test is able to account for as much as twenty percent of the total variance accounted for in the criterion test that assesses relationship satisfaction, that still leaves eighty percent of the psychological factors that contribute to marital happiness that are measured by the criterion test unaccounted for by the compatibility test," explained Doctor Lawson. developed the Compatible Lifestyle Questionnaire-R (C.L.Q), which accounts for one third of the total variance in the Dyadic Adjustment Scale (D.A.S.) (Copyright, 1989, Multihealth Systems), according to Doctor Lawson. The D.A.S. has been used in more than 1000 research studies to assess long term relationship adjustment and satisfaction.

"Our compatibility test was developed with the Dyadic Adjustment Scale, the same scale that was used by eHarmony to develop their compatibility test," stated Dr. Lawson. The D.A.S. was also used by eHarmony in 2005 in a predictive validity study they reported in 2006. eHarmony used the D.A.S. as a criterion measure of relationship happiness in couples who were married after meeting on their website, compared to married couples who did not meet on their website, according to Doctor Lawson.

"We agree with eHarmony that the D.A.S. is an excellent criterion measure to use for developing compatibility tests and as a criterion measure for predictive validity studies," stated Doctor Lawson.

"We are proposing a university monitored study that would compare the validity of our test, the C.L.Q., to the validity of the compatibility test used by any other online dating site. If more than one dating site wishes to participate, they would be welcome to do so," said Doctor Lawson.

"We do insist that the D.A.S., which is a widely accepted psychological test of relationship adjustment and satisfaction, be used as the criterion measure, or dependent variable in such a study. We are also adamant that the standard used to measure the validity of our test , when it is compared to the validity of any competitor's test, be the variance accounted for in the D.A.S. by the compatibility test," stated Doctor Lawson.

He added that study requirements would include a double-blind design in which married couples who are randomly selected for the study would complete the D.A.S. along with the compatibility tests used by and by the competing website. He added that other psychological tests that have been widely used in the psychological literature to assess marital happiness could additionally be used as dependent variables for convergent validity purposes.

He stated that any online dating site that is willing to compete in such a study must also agree to pay for the entire study. A further requirement would be that the study be carried out by doctoral level statisticians at either Michigan State University , the University of Michigan , or, The Ohio State University. The study would then be submitted for professional peer review and possible publication or presentation at a professional meeting of psychologists. is an online dating site that offers free online dating and free compatibility tests for couples. allows dating site members to view all other members' profiles. They are allowed to take control of the compatibility matching process by viewing compatibility scores between themselves and each other member, according to Doctor Lawson.

The C.L.Q., the dating site's compatibility test, provides each dating site member with an overall composite compatibility score of each profile viewed, along with compatibility scores on seven scales, including personality, communication and conflict resolution, sexual and romantic style, financial style, coping style, interests, and family values, according to Doctor Lawson.
