     We show that the ${\displaystyle p}$-power maps in the first Hochschild cohomology space of finite-dimensional selfinjective algebras over a field of prime characteristic ${\displaystyle p}$ commute with stable equivalences of Morita type on the subgroup of classes represented by integrable derivations.
