The lifetimes of states in Superdeformed (SD) bands in {sup 192, 194}Hg, {sup 151,152}Dy, and {sup 151}Tb have been measured using the Doppler shift attenuation method. Intrinsic quadrupole moments Q{sub 0} have been extracted for SD bands in these nuclei. It was found that the quadrupole moments for the ``identical`` SD bands in these nuclei are the same. In the A = 150 region, changes were found in the Q{sub 0} values as a function of the number of high-N intruder orbitals. Changes are present also for excited SD bands with the same high-N content. Recent calculations account for most of the observations in the A = 150 region.
