Effects of strong final-state interactions in the superscaling properties of neutral-current quasielastic neutrino cross sections are investigated by using the relativistic impulse approximation as guidance. First-and second-kind scaling are analyzed for neutrino beam energies ranging from 1 to 2 GeV for the cases of 12 C, 16 O, and 40 Ca. Different detection angles of the outgoing nucleon are considered to sample various nucleon energy regimes. Scaling of the second kind is shown to be very robust. The validity of first-kind scaling is found to be linked to the kinematics of the process. Superscaling still prevails even in the presence of very strong final-state interactions, provided that some kinematical restrains are kept, and the conditions under which superscaling can be applied to predict neutral-current quasielastic neutrino scattering are determined.
