Symptoms of withdrawal
Symptoms of withdrawal during the SSB withdrawal period (days 6-8) will be compared to symptoms of withdrawal during usual consumption period (days 1-3). Three measures are used to assess withdrawal symptoms: Griffiths' withdrawal scale, the relative reinforcing value of soda, and daily check in questions on well-being.
Time frame: Days 1-3 and days 6-8
Change in diet
Changes in diet will be assessed by 24-hour dietary recalls and beverage recalls
Time frame: Days 1-2, 6-8
Change in impulsivity
Impulsivity will be assessed via the delayed discounting task
Time frame: Days 1 and 8
Change in stress
Stress will be assessed via salivary cortisol samples
Time frame: Days 1 and 8
Change in preference for soda
Preference for soda will be measured through the Labeled Affective Magnitude Scale (LAMS) and daily check-in questions
Time frame: Days 1-3, 6-8
