Abstract

This study was conducted to verify the stability of validity in two female sales jobs(1130 life insurance sales women and 282 female tele-marketers). After a series of item analyses were conducted for each group, 37 items and 33 items among 75 biographical items were included to the validation study, respectedly. The resulting validities and cross-validities were generalizable, regardless of whether sample size of item-keying group was large or small. But, large sample-based empirical keys showed larger cross-validity than small sample-based empirical keys. The finding in this study show that large sample-based keying of biodata scale can yield generalizable validities. And, the current findings suggest that consortium-based, multiple-organization biodata researches are needed.
