Further study details as provided by Jesse Dallery, National Development and Research Institutes, Inc.:

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


Secondary Outcome Measures:
  • 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.

  • 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.

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

Arms Assigned Interventions
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.
