validity and reliability of personality tests

This produces a spread of scores to assess the order of preferences between the dominant and inferior functions. This is in effect forcing a choice between opposed functions with their respective attitudes of extraversion and introversion, for example extraverted thinking with introverted feeling.Ī normative element is created by asking the respondent to further weight the other word pairs while not choosing the same weighting twice. To measure the dominant and inferior a most and least forced choice must be made in every frame. 10 frames each containing four word pairs, which describe the functions and their attitudes. Two methods are combined to improve the accuracy of the questionnaire, a choice forced between most and least and the freedom to weight the other two items. PeopleMaps is a type measure which takes account of interactive scales. (Some ipsative questionnaires only measure Most and Least and thereby lose accuracy.) All four are weighted, which improves the accuracy of the questionnaire. On each of the four the respondent will choose which they believe is most like them and and which is least. The PeopleMaps questionnaire provides an Ipsative questionnaire, which means that it is self report and the respondent’s choosing from a selection of four word pairings. discriminating between individuals, PeopleMaps does not discriminate in this way.

Profiling that is not Jungian based will normally be norm referenced, i.e. Hundreds of thousands of people have contributed to these findings, which also confirms reliability. That the profile has measured personality accurately is confirmed by the respondents face validity. The measures used are Jung’s Rational and Irrational preference scales, together with his Extraverted and Introverted attitude scales. PeopleMaps is a Jungian profile designed to measure personality. Reliability is concerned with the consistency of assessments. It implies comparison between the assessments and some external criteria. Validity or validation is concerned with the extent to which an assessment instrument actually measures what it is designed to measure.
