Arms and Interventions
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Arm Intervention/treatment
Experimental: Full Group Contingency
This group (n = 20) will earn vouchers based only on team (n = 4) performance. Only if all members of the team submit a negative sample (CO ≤ 4 ppm), will they each earn a voucher.
 Behavioral: Full Group Contingency
This group (n = 20) will earn vouchers based only on team (n = 4) performance. Only if all members of the team submit a negative sample (CO ≤ 4 ppm), will they each earn a voucher.
Experimental: Mixed Group Contingency
This group (n = 20) will earn vouchers based on both individual and team (n = 4) performance. If an individual submits a negative sample (CO ≤ 4 ppm), s/he will earn a voucher. Additionally, bonus vouchers will be earned if all team members submit negative samples.
 Behavioral: Mixed Group Contingency
This group (n = 20) will earn vouchers based on both individual and team (n = 4) performance. If an individual submits a negative sample (CO ≤ 4 ppm), s/he will earn a voucher. Additionally, bonus vouchers will be earned if all team members submit negative samples.


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Breath CO [ Time Frame: 8 weeks ]
    Twice daily breath CO samples obtained during baseline and treatment


Secondary Outcome Measures :
  1. Point prevalence measure of abstinence [ Time Frame: at the end of treatment (approximately week 4) and at 3 month follow-up ]
    Abstinence will be defined as: (a) CO sample ≤ 4 ppm; (b) cotinine < 50 ng/ml; and (c) reporting not smoking, not even a puff in the last 7 days.

  2. Duration of abstinence during treatment. [ Time Frame: 3 weeks ]
    The longest duration of sustained abstinence (CO ≤ 4 ppm) based on the twice-daily breath samples during the treatment period.

  3. Rate of social exchanges [ Time Frame: 3 weeks ]
    The number of comments posted on the discussion forum during treatment.
