Individual psychodynamic psychotherapy is a recommended, but controversial, treatment for patients with personality disorders (PDs). The aim of this study was to examine the relationship between demographic and professional characteristics of experienced psychotherapists and their attitudes and opinions towards aspects of this kind of psychotherapy. A questionnaire covering these issues of psychodynamic psychotherapy with patients belonging to all three DSM-IV clusters of PD was developed. A sample of 324 Norwegian psychiatrists and clinical psychologist with considerable experience in individual dynamic psychotherapy of patients with PDs filled in valid questionnaires. The therapists' age, gender, profession, postgraduate courses and degree of experience were examined as to their opinions on the following issues: alliances, aims, contraindications, needs to terminate, suicides, use of drugs, length of treatment, need for supervision and complaints to colleagues about patients' behaviour in such therapy with PD patients. Independent sample t-tests of the mean z-transformed group scores were the main statistical method applied. Therapist experience made the most significant differences as to treatment issues, while some differences also were found for age, gender and profession. The influence of postgraduate courses was negligible. Our study might have a selection bias towards therapist with strong psychodynamic orientation and particular interest in the psychotherapy of patients with PDs.
