Researchers measured the risk of coronary heart disease and the degree of expression of positive emotions of 1, 739 healthy adults who participated in the study. The patients were then monitored for a period of 10 years for incidence of coronary heart disease.

Which of the following conclusions can you make on the basis of this study? There is no relationship between positive affect and coronary heart disease. Positive affect prevents coronary heart disease. Negative emotions contribute to the development of coronary heart disease. Positive affect is associated with a lower risk of coronary heart disease.
