Transport coefficients for Coulomb collision processes, e.g., friction, energy exchange, and resistivity, are calculated for Debye-screened (Yukawa) plasmas including correlation effects within the binary collision approximation. A generalized Coulomb logarithm, Ξ(Λ), is required, which asymptotes to ln Λ in the weakly coupled limit, but is significantly modified when Λ\lesssim 102 due to large angle collisions. In the regime 10-2 \lesssim Λ\lesssim 102, Ξ can be substantially larger for attractive collisions than repulsive.
