PsychTests Launches MatchScale, the Blueprint for Compatibility

MONTREAL, CANADA -- August 24 , 2005

After 10 years of developing psychological assessments for web-surfers and businesses around the world, PsychTests has unveiled its latest high-tech offering, MatchScale. This unique and exhaustive web-based compatibility testing system is destined to have a major influence in online dating, relationship counseling and pre-marital assessments.

Most dating sites offer demographic matching to their members, suggesting potential romantic partners based on their age, hair color, hobbies and the like. While such criteria are important for filtering possible matches, they are only the tip of the iceberg when it comes to figuring out if a couple will actually be happy together. Numerous studies have shown that the success of a relationship depends mostly on the couples' personalities, communication styles and values. The vast majority of dating sites either ignores or assesses inadequately the main ingredient – chemistry.

MatchScale is in an entirely different league. The system was developed by a team of online testing veterans, with some 200 scientifically valid assessments under its belt. Using the most recent and reliable research as their foundation, PsychTests has designed an in-depth questionnaire that gets to the heart of what makes a relationship work. Unlike other personality matching systems that reduce relationship dynamics to either "opposites attract" or "birds of feather", MatchScale's artificial intelligence algorithms closely model the complexity of real life. Each trait has its own fine-tuned set of rules that synthesizes scientific findings, expert judgement and empirical data. Various trait interactions are also evaluated. The test adheres to the APA's (American Psychological Association) rigorous standards for test development.

"We wanted to create a test that would give people the tools they need to understand themselves as well as their relationship dynamics," says Ilona Jerabek, Ph.D., president of PsychTests. "The feedback we've received from our customers about the accuracy of their results has been outstanding."

MatchScale is PsychTests' most comprehensive assessment to date. Created by an experienced team of psychologists, programmers and designers who have previously developed a compatibility test for one of the net's top dating sites, it analyzes more attributes than any other test designed for matching couples. From conflict resolution styles to their need for space, the test measures over 150 attributes that factor into short- and long-term relationship satisfaction.

Based on an expanded Big Five Personality Factor Model, MatchScale offers two extensive personalized reports. The Personal Report provides test-takers with insight into why they do what they do. Most importantly, the results help them understand how these attributes affect their relationship dynamics. A Match Report is also generated for every potential couple. "The multi-layered artificial intelligence behind our system had to be quite complex," says Jerabek. Couples can get an objective look at their overall compatibility, along with interesting details about their relationship dynamics. Customized advice helps them develop a strong foundation for a lasting relationship.

This innovative system is currently available to dating websites and relationship counselors. The members on MatchScale clients' sites can use this unique test to improve their understanding of how their personalities affect their satisfaction in a relationship.
