MPQ and BISBAS Personality Scale/Score?

Asked by DrasticDreamer (23983points) September 19th, 2014

I can find a lot of information about the theories behind the tests, but I can’t find any scales to indicate what the scores for the tests mean. For instance, if someone scored 45 what would that be indicative of? If someone scored -1, what would that be indicative of?

I’m really hoping someone can point me in the right direction here. Anyone?

The score analyses are probably not widely available because their availability would enable people to easily game the scoring system – these tests have been monetized after all.

If you’re looking into these tests as part of a university course, you’ll probably be able to access the original paper that outlines the personality scale, which (I think) is:

Tellegen, A., Lykken, D. T., Bouchard, T. J., Wilcox, K. J., Segal, N. L., & Rich, S. (1988) Personality similarity in twins reared together and apart, Journal of Personality and Social Psychology, 54, 1031 – 1039

From what I’ve read on these tests (which is admittedly not a great deal – I’m more interested in the Minnesota Multiphasic Personality Inventory, a related test), the scores are awarded based on true/false answers to a bank of questions; I don’t think it’s just a case of score = personality, rather a case of the scores for each trait measured representing traits under each personality domain.

What you need to establish is what personality trait each individual question measures and what, therefore, scores for each domain mean.

MMPI or Minnesota Multiphasic Personality Inventory has been around for years, it has been use in Psychiatry for therapy plans. It can be gamed if the person taking the test knows which question cards are used for a over or under reporting a condition.

One aspect of the MMPI is its ability to detect attempts to game the test. The first three scores indicate too much or too little lying. I self administered this test when I worked at a mental hospital and was concerned when the graph of the scores showed a bat wing profile, often indicative of psychoses. Without reveling that I had taken the test showed it to the staff psychologist who was running in service training. He showed me that the plot was to the left of those indices and that the only notable scores were the first three that seem too truthful. Then he realized I had taken the test.
