Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

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.

Group Type EXPERIMENTAL

Full Group Contingency

Intervention Type BEHAVIORAL

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.

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.
