The purpose of this paper is to describe and evaluate the ability of instruments to produce information about the presence and intensity of fear before, during and after coronary arteriography. Information about patient fear was measured from cognitive, physiological and behavioural dimensions. The sample of the study was 243 patients who were due to have a scheduled coronary arteriography in a university hospital in Finland. Fear was measured by the Visual Analogy Scale (VAS), Hospital Anxiety and Depression (HAD) Scale and State-Trait Anxiety Inventory (STAI). Physiological measurements (blood pressure and heart rate) were obtained. The VAS was given to 46 nurses and seven nurse assistants to measure nurses' perception of patient fear. Over 80% of the patients reported fears. Nurses perceived that the patients had more fears than they reported. Changes in physiological measurements were small but significant. One-third of the patients felt increased fear after the coronary arteriography. VAS, STAI and HAD produced reliable information about the patient fear. The correlations between the instruments suggest that each is a valid and appropriate measure of fear. Nurses need to develop their communication and observation skills in order to develop their recognition of the patients' fear.
