Assessing the psychological effects of an exercise training programme for patients following myocardial infarction: a pilot study.

During a study investigating physiological and other effects of an exercise programme for coronary patients, a questionnaire was administered. Preliminary analysis had suggested some improvement in the patients' morale, but in view of the possible relevance of a number of psychological variables it was decided to carry out further analysis on the available data. The coefficient of discrimination was computed for 32 patients. For 19 patients correlations were computed between scores on subjective fitness, symptoms, anxiety, interest in sex, if at work, age, weight, and workload achieved at a given heart rate. The questionnaire appeared to have satisfactorily high internal and external validity. Patients with a high 'morale' score tended to achieve a greater increase in workload over the course. Although cause and effect cannot be unequivocally assigned, the association is felt to be important, and research is continuing.
