The self-energy screening correction is evaluated in a model in which the effect of the screening electron is represented as a first-order perturbation of the self-energy by an effective potential. The effective potential is the Coulomb potential of the spherically averaged charge density of the screening electron. We evaluate the energy shift due to a 1s1/2, 2s1/2, 2p1/2, or 2p3/2 electron screening a 1s1/2, 2s1/2, 2p1/2, or 2p3/2 electron, for nuclear charge Z in the range 5<~Z<~92. A detailed comparison with other calculations is made.
