In addition to the well-known criteria for terminating an analysis such as heterosexual potency and capacity for love, object relationships and work, Melanie Klein adds the following: have persecutory and depressive anxieties been sufficiently reduced and has the patient's relationship to reality been sufficiently strengthened to enable him to deal with a situation of mourning? If the negative and positive transference, the idealization and the feelings of being persecuted by the analyst, have been sufficiently analyzed, then the patient will be able to cope successfully with feelings of loss caused by termination, and with that part of the work of mourning which he must subsequently carry out by himself.
