The Role of Contingency Management in Waterpipe Smoking Cessation

Monetary incentive for the CM groups is contingent on a saliva cotinine reading that indicates smoking abstinence. Participants were assessed 10 times (Mondays/Thursdays) for abstinence from smoking waterpipe verified by saliva cotinine. The maximum monetary incentives this group can receive is $192.50. The CM groups followed an escalating schedule where: 1) the dollar amount of the incentive increases by $.50 as long as the participant is abstinent at each visit;; and 2) resets to the starting incentive ($14) if the participant was non-compliant at the previous visit, but is compliant at the current visit. Also, Participants were given $10 bonus for every three consecutive compliant visits.
