Validity of two brief measures: the General Abilities Measure for Adults and the Shiple Institute of Living Scale.

The present investigation examined the concurrent validity of the General Ability Measure for Adults by Naglieri and Bardos (1997) and the Shipley Institute of Living Scale by Zachary (1991). These scales were administered to 129 college students who ranged in age from 18 to 55 years (M age=24.8 yr.). Pearson correlations were computed to evaluate the association of scores on these measures. Significant small correlations were found for GAMA IQ scores with scores on the Shipley Verbal (r = .29) and Total scales (r = .28) but not with scores on the Shipley Abstraction subscale (r=.11). Although the GAMA has been presented as a measure of general intelligence, only partial support for this view was found.
