Peer reviewedForsterlee, Robert; Ho, Robert – Educational and Psychological Measurement, 1999
Studied the factor structure of the Need for Cognition Scale (NFC) (J. Cohen, E. Scotland, and D. Wolfe, 1955) (short form) with samples of 510 and 697 Australian adults. Results support the use of the short version of the NFC with Australian samples. (SLD)

Peer reviewedBell, Richard; Lumsden, James – Applied Psychological Measurement, 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)
