Abstract
The present study examined the psychometric properties, including factor structure, reliability, and validity of the Ksiazak Adult Giftedness Scale, a measure of characteristics of adult giftedness. Principal components analysis, as well as analyses of correlations between scores on the Ksiazak Adult Giftedness Scale and other measures, were performed to answer three research questions: 1) Can a reliable measure of characteristics of adult giftedness be developed? 2) Can a valid measure of characteristics of adult giftedness be developed? and 3) What is the factor structure of a measure of characteristics of adult giftedness? Results indicated that the Ksiazak Adult Giftedness Scale has adequate reliability and validity and appears to have a unifactorial structure. Theoretical, research, and practice implications are discussed in relation to the findings. Methodological limitations to the study and directions for future research are also offered.
