Test Length and Validity.
Bell, Richard; Lumsden, James
Applied Psychological Measurement, v4 n2 p165-70 Spr 1980
The effect of test length on predictive validity is examined empirically. For four tests, the curve of validity against test length had a very gentle slope for the longer tests and all tests could be reduced by more than 60 percent without appreciable decreases in validity. (Author/BW)
