In this case report integrative psychotherapy with cognitive-behavioral, psychodynamic, and supportive psychotherapy techniques were used to provide treatment to the patient with delusional disorder, persecutory type. The patient was stable on antipsychotics and antidepressants during the psychotherapy process. The patient’s main delusion was being followed and called ‘loser’ by others. He believed people on the street knew he had not worked and devalued him for not having worked. In the beginning of the therapy, the patient was able to finish his exercise, i.e. walking, 40% of the time, only with great anxiety. During the therapy, the patient’s thoughts, feelings, and behaviors were followed using cognitive-behavioral forms. Several forms including tracking degree of thought, using the vertical descent, cost-benefit analysis, point and counter-point, examining the evidence were used to track the patient’s progress. In addition, the patient’s problematic relationships with his family were discussed from a psychodynamic perspective in order to provide meaning and insight into the source of his difficulties. When the therapy ended, the patient was able to complete his exercise 90% of the time he attempted walking in the park, which suggested an improvement in his target complaint.
