The purpose of this study was to determine whether (a) symptoms of dep
ression are more prevalent and severe among diabetic smokers than diab
etic nonsmokers, (b) smoking is related to depressive symptomatology a
mong diabetic patients, and (c) there is a positive relationship betwe
en number of cigarettes smoked and severity of depressive symptoms. Di
abetic non-smokers (n = 103) and diabetic smokers (n = 83) were survey
