    Differential item functioning on the Myers-Briggs type indicator
    Greenberg, Stuart Elliot (Virginia Tech, 1992-10-15)
    Differential item functioning on the Myers-Briggs Type Indicator (MBTI) was examined in regard to gender. The Myers-Briggs has a differential scoring system for males and females on its thinking/feeling subscale. This scoring system preserves the 60 % thinking male and 30 % thinking female proportion that is implied by the Jungian theory underlying the Indicator. The MBTI's authors contended that the sex-based differential scoring system corrects items that subjects at a certain level of a latent trait either incorrectly endorse or leave blank. This reasoning is the classical definition of differential item functioning (DIF); consequently, the non differentially scored items should exhibit DIF. If these items do not show DIF, then there would be no reason to use a differential scoring system. Although the Indicator has been in use for several decades, no rigorous item response theory (IRT) item-level analysis of the Indicator has been undertaken. IRT analysis allows for mean differences in subgroups to occur, independent of the question of DlF. Linn and Harnisch's (1981) pseudo-lRT analysis was chosen to test for the presence of DlF in the MBTl items because it is best for tests of relatively small length. The Myers-Briggs subscales range from 22 to 26 items, which is relatively small by lRT standards. lRT analyses conducted on N=1887 subjects indicated that no items on the thinking/feeling subscale showed evidence of DIF. Out of 94 items, only one extraversion/introversion item and one judging/perception item showed evidence of DIF; no Thinking/Feeling items showed DIF. It is recommended that sex-based differential MBTI scoring be abandoned, and that the distribution of type in the population be examined in future studies.

    Measuring absence cultures: an examination of absence perceptions of males and females
    Greenberg, Stuart Elliot (Virginia Tech, 1989-12-15)
    Absenteeism was explored from a social psychological perspective. The purpose was to measure the absence cultures (Nicholson and Johns, l9S5) of male and female employees through the use of policy capturing (Hobson and Gibson, l9S3). Absence was split into three dimensions: Personal Health, Stress Relief, and Family Responsibility (Nicholson and Payne, l9S7). One hundred and two employees of a large southeastern university were used as subjects. They were asked to give their own opinion and their opinion of their organization's view about the inappropriateness/appropriateness of the absence behaviors in the 27 policy capturing vignettes. They were also asked to give their subjective weighting of how they used each dimension to make their overall rating.
