Secondary outcomes

1

Nicotine dependence, as measured by the Fagerstrom Test for Nicotine Dependence

The Fagerstrom Test for Nicotine Dependence is a self-report measure that classifies level of nicotine dependence. Participants respond to a series of questions assessing time of first cigarette after waking, difficulty refraining from smoking in places where smoking is prohibited, and frequency of smoking. Total score range 0-10 with higher scores indication more nicotine dependence.

Time frame
Baseline and Week 16
2

Depressive symptomatology, as measured by the Patient Health Questionnaire-9

The Patient Health Questionnaire-9 is a brief, psychometrically sound, and widely used self-report measure of depression in diverse medical settings. The total score on the PHQ-9 ranges from 0 to 27, with higher scores indicating greater severity of depressive symptoms.

Time frame
Baseline and Week 16
3

Physical activity, as measured by the Global Physical Activity Questionnaire (GPAQ)

GPAQ is a validated self-report assessment of physical activity and sedentary behavior. GPAQ does not have a single fixed total score range but a score is calcualed in METs-minutes per day. Participants are classified as "active" if they meet or exceed 600 METs-minutes per week.
