BACKGROUND Several large-scale prospective studies have failed to find an association between Type A personality (TAP) or hostility and coronary heart disease (CHD). The existing meta-analyses on this topic have several shortcomings, such as a selective search of the literature, the failed use of effect sizes, and methodological flaws. METHODS The present(More)
The well-known negative correlation between initial value and difference score, referred to as the law of initial value (LIV), is analyzed in the present study. It is shown that whenever the correlation between the initial and final values is less than 1.00, the negative correlation is influenced by the a(a - b) effect. By relating values to the first(More)
Ambulatory assessment refers to the use of computer-assisted methodology for self-reports, behavior records, or physiological measurements, while the participant undergoes normal daily activities. Since the 1980s, portable microcomputer systems and physiological recorders/analyzers have been developed for this purpose. In contrast to their use in medicine,(More)
Blood pressure is one of the most commonly recorded functions in physiology and medicine, and it has become a major variable in recent psychophysiological and behavioral medicine research. Many methods have been developed for the measurement of blood pressure in clinical, laboratory, and natural settings. The broad objectives of this report are to summarize(More)
Five studies with nearly 500 subjects recruited from the university, the work place, and from rehabilitation clinics served to investigate the perception of emotional events in everyday life. Physiological parameters (heart rate, physical activity, additional heart rate) and psychological parameters (excitement, enjoyment) were assessed simultaneously(More)
Additional heart rate as an indicator of emotional arousal was monitored throughout the day with a special ambulatory device. Fifty female students received acoustic feedback every 10-20 min. The feedback was based either on events (additional heart rate present) or was random without additional heart rate. Following the feedback the subjects were asked to(More)
Heart rate is a well-established indicator of emotional arousal and can serve to detect emotional events. One difficulty, however, is in separating emotional heart rate increases from those increases due to physical activity. On-line analysis of both heart rate and physical activity (recorded with motion detectors) with a portable minicomputer may be able(More)

One year after an inpatient cardiac rehabilitation programme, 83 out of 105 male cardiac patients were subjected to a follow-up study. Data collection comprised the Life Satisfaction Questionnaire, the Freiburg Personality Inventory, the Freiburg Somatic Complaint List, an adjective list for current mood, and a follow-up questionnaire assessing life habits,(More)
