  We determine the anomaly associated to an arbitrary scaling of the fields in
a quantum gauge theory without making use of the Fujikawa method. We show that
this anomaly is dependent on the spin term present in the action and at one
loop can be directly extracted from the spin contribution to the one loop
effective action. Our results can be readily applied to any gauge theory,
supersymmetric or not and agree with previous determination for supersymmetric
gauge theories based on the Fujikawa method.
