The invention provides a method in vivo detecting anti-D3 receptor activity of dopamine D3 receptor ligands. The method of the invention makes use of a NMDA glutamate receptor antagonist to induce D3-mediated behavioral abnormalities and assess reversing effects of candidate ligands. The invention further relates to the use of a dopamine D3 receptor partial agonist or antagonist for the treatment of a substance-induced psychotic disorder or a dyskinesia associated with associated with dopamine agonist therapy.
