QUESTIONNAIRE ON SMOKING HABITS
BehavioralData on smoking will include the age at which cigarette smoking began and ceased and the average amount smoked daily. Intensity (number of cigarettes smoked per day), duration of smoking (years), and time since cessation (years) will be categorized. Also, the smoking status of the patient prior psoriasis diagnosis will be assessed (smoker or non-smoker and years of smoking prior to psoriasis diagnosis).
Smoking habit evaluation: baseline and changes in smoking habit at 12 and 24-weeks follow-up time points.
