| Tiivistelmä: | Ipsative questionnaires of personality have been attacked as inferior to normative approaches. (A personality, motivation or interest questionnaire is said to be ipsative when the sum of the scores obtained over the attributes or scales measured for each respondent is a constant.) A recent investigation shows that this criticism is ill-advised. The results demonstrate with simulated data that ipsative scores can be factored soundly, that reliability data are not overestimated, and that under moderate conditions of central tendency bias in normative items, ipsative scores actually correlate better with hypothetical "true" scores than the normative form. |
