We extend our previous calculation of the quasilocal contribution to the self-force on a scalar particle to general (not necessarily geodesic) motion in a general spacetime. In addition to the general case and the case of a particle at rest in a stationary spacetime, we consider as examples a particle held at rest in Reissner-Nordström and Kerr-Newman spacetimes. This allows us to most easily analyze the effect of nongeodesic motion on our previous results and also allows for comparison to existing results for Schwarzschild spacetime.
