We investigated the dependence of the K(-)d scattering length on two models of (K) over barN interaction, providing one or two poles for the Lambda(1405) resonance. The (K) over bar NN - pi Sigma N system is described by coupled-channels Faddeev equations in AGS form. The two-body (K) over barN - pi Sigma interaction models reproduce all existing experimental data on K(-)p scattering and K(-)p atom level shift. The comparison with several approximations, commonly used for such calculations, was done
