In the present letter, we consider the DeBroglie-Bohm interpretation of quantum Friedmann-Robertson-Walker models in the presence of a negative cosmological constant and cosmic strings. We compute the Bohm's trajectories and quantum potentials for a quantity related to the scale factor. Then, we compare our results with the ones already in the literature, where the many worlds interpretation of the same models was used.
