Home measures of anxiety, avoidant coping and defence as predictors of anxiety, heart rate and skin conductance level just before invasive cardiovascular procedures.
The question was whether anxiety, heart rate and skin conductance level just before invasive cardiac procedures could be predicted by anxiety related measures obtained at patients homes approximately 3 weeks before treatment. Trait measures of avoidant coping and defence were provided by sixty-three male and thirty-three female patients who were scheduled for a diagnostic or interventional heart catheterization. In hospital physiological measures were registered continuously during a 20 min interview and subsequently patients reported their anxiety. Results with hierarchical regression analysis showed that sex, age, medical variables and state anxiety at home explained 62% of state anxiety in hospital. Female sex predicted high anxiety in hospital while advanced age predicted low anxiety. Medical variables and measures of coping and defence did not add a significant contribution to this prediction of anxiety. Skin conductance and heart rate measures could not be predicted by the psychological measures collected at home.
