Brief summary
Smoking during pregnancy has harmful effects on both mother and unborn child. Studies have shown that small rewards can help smokers to quit. In our current study, we ask how such rewards are most effective in supporting smoking cessation in pregnancy.
Detailed description
We would like to include up to 15 pregnant women. Inclusion criteria are: (i) current pregnancy, between pregnancy week 15 and 23 and, (ii) current smoking of at least one cigarette per day. After an initial survey, the participating women are scheduled twice a week for counseling and evaluation of their smoking status.They will receive cash payment of 25 Euro if her carbon monoxide reading does not exceed the value 3, on two consecutive dates per week. A second survey will be conduced in pregnancy week 36 and a third survey, eight weeks postpartum.
Interventions
BEHAVIORALCash payment and brief behavioral counseling
The intervention consists of: (i) in person brief behavioral counseling, (ii) the evaluation of the smoking status using breath carbon monoxide, and (iii) cash payment of 25 Euro if the reading does not exceed a carbon monoxide value 3 ppm ( ppm = parts per million) on two consecutive measurements per week. The intervention starts at the earliest in pregnancy week 15 and lasts until the delivery. If they relapse, the reward is not paid. However, in the following week they have the opportunity to quit smoking and being rewarded again.
