Dear All,
I'm a postgraduate student in psychology, and I recently encountered difficulties with the accuracy of personality measurements.
Among the five domains of the Big Five personality measurement, which domains are more accurate in self-reporting and which domains are more accurate in others' reporting? Is there any relevant newer literature?
I look forward to getting some help. Thank you!
Personality measurement is an attempt to estimate human unique characteristics from an outsider perspective using often some valid and reliable measures. The accuracy of such measures is usually a matter of degree, never absolute or 100%.
However, the main guide to the degree of accuracy is a factor of the validity and reliability of the psychological (Personality) tests used. Usually, the use of triangulation in Personality assessment is recommended. By this is meant the need to measure personality from different perspectives/ test protocol. This is a good way to ensure high level of accuracy especially if all the tests point to the same direction.
It depends what do you mean on accuracy. Is it category of realiabilty or of validity or something else. According to psychometric rules accuracy is determined by standard error of measurement. However in classical test tradition error of measuremnt is not calculated obviously. It is expressed through realiability. The higher is reliability the greater is accuracy. In Rasch measurement theory accuracy is more elaborated conception and depends upon relations between item difficulty and person ability (e.g. personality trait). So there are several solutions of your question depending of what measurement theory is of your choice. For theoretical prepositions, I think extraversion-introversion is assessed with maximum accuracy, whereas openness is assessed with the lowest accuracy.
Personality assessment is a product of multiple sets of psychological tests. A minimum of three is quite acceptable. The accuracy is on the patterns shown by the results. Result from a single test is not reliable that is why there must be other similar tests to be administered. Eg. Draw-A-Person Test (DAPT) should be supported with Sach's Sentence Completion Test (SSCT) and probably 16 PF-R or Bender-Gestalt Test. The repeated characteristics or behaviors that will manifest from the various tests are the reliable results.
It is curious what we want to measure and who it is supposed to serve. In my opinion, this is to serve the client so that he can somehow direct his life and its spaces. As a practitioner of psychosynthesis, I have observed remarkably consistent with the person I work with the TPP personality profile test. This is a qualitative test of managerial and organizational psychosynthesis, which extremely clearly shows the consistency of the main characteristics discovered and the feelings of the subject. No one has yet told me that it is different from his feelings, in fact, everyone responds that they have never received something so precise about him before.
