Note. ACS = Acute Coronary Syndrome. STEMI = ST segment elevation myocardial infarction. NSTEMI = non-ST segment elevation myocardial infarction. COPD = Chronic Obstructive Pulmonary Disease. DASI = Duke Activity Status Index. CESD-10 = Center for Epidemiologic Studies Depression Scale – Short Form. PANAS = Positive Affect Negative Affect Scales
a
Predicts higher positive affect after controlling for DASI score at p <.05.
b
Predicts more depressive symptoms after controlling for DASI score at p <.05
c
Predicts higher negative affect after controlling for DASI score affect at p <.05
d
Predicts post-ACS smoking status after controlling for DASI score at p <.05
