N2 - The 1-year temporal stability of the Wechsler Adult Intelligence Scale - Revised (WAIS-R) Full Scale IQ (FSIQ) and several predictors of intelligence, including the A. Barona and R. Chastain (1986) demographic predictor formula, the New Adult Reading Test-Revised (NART-R:J. Blair and O. Spreen, 1989), and the Intellectual Correlates Scale (ICS: R. Schlottmann and D. Johnsen, 1991) were investigated in 51 normal older persons. Reliability of WAIS-R FSIQs and Barona, NART-R, and ICS estimates of FSIQ fell at .90, .99, .92, and .58, respectively (all ps <.05). Estimates of FSIQ generated by the Barona, NART-R, and ICS correlated significantly with concurrent FSIQ obtained on the 1st (r =.61, .73, and .48, respectively) and 2nd observations (r = .63,.73, and .41, respectively). A simple average of Barona and NART-R estimates derived from the 2nd observation correlated at .75 with WAIS-R FSIQs obtained 1 year earlier.
