A nonlinear theory of kinetic instabilities near threshold [Berk {ital et al.}, Plasma Phys. Rep. {bold 23}, 842 (1997)] is applied to calculate the saturation level of toroidicity-induced Alfv{acute e}n eigenmodes (TAE), and to be compared with the predictions of {delta}f method calculations (Y. Chen, Ph.D. thesis, Princeton University, 1998). Good agreement is observed between the predictions of both methods and the predicted saturation levels are comparable to experimentally measured amplitudes of the TAE oscillations in Tokamak Fusion Test Reactor [D. J. Grove and D. M. Meade, Nucl. Fusion {bold 25}, 1167 (1985)]. {copyright} {ital 1999 American Institute of Physics.}
