Aim of the study:
The aim of the study was to examine the physiological activity in patients and psychotherapists during psychodynamic psychotherapy in relation to: gender, presence of personality disorder traits and anxiety symptoms.

Subject or material and methods:
Physiological data of 24 patients with a diagnosis of neurotic disorders and/or personality disor-ders were analysed. Psychotherapy was conducted by two psychotherapists. Most patients had an anxiety disorder or a specific personality disorder. Physiological data were collected using a galvanometer and a pulsometer.

Results:
The physiological activity of the psychotherapists differed, probably due to their professional experience. The physiological activity of the patients differed due to the psychotherapist providing therapy, gender, personality traits, and level of neurotic symptoms.

Discussion:
Differences in the physiological parameters of psychotherapists could be related to individual differences between them: gender, age, education, and length of professional experience. Length of the experience and gender of therapists could have influenced patients' physiological reactions. Patients' dominant symptoms could be related to the intensity of their physiological reactions. Due to the significant and interesting results of the study it would be worth repeating it on a larger number of patients and psychotherapists.

Conclusions:
The physiological state of the psychotherapists correlate with the physiological reactions of the patients. The results suggest higher EDA (electrodermal activity) and lower HR (heart rate) in neurotic disorders and higher HR activity and lower EDA in personality disorders.
