For point charges within an electric field, the natural direction a point charge takes in respect to a field would be towards lower potential energy, whereas the work done by the conservative force should be positive. So then, by W = -q*deltaV, do they refer to the magnitude of the test charge q? If deltaV was negative, it indicates that positive work was done...but if the charge is negative, the work becomes negative.
