Drug users' adherence to a 6-month vaccination protocol: effects of motivational incentives.
Vaccines represent a new and promising avenue of treatment for drug abuse but pose new medication adherence challenges due to prolonged and widely spaced administration schedules . This study examined effects of prize-based incentives on retention and medication adherence among 26 cocaine users involved in a 6-month hepatitis B vaccination series . Participants could meet with research staff weekly for 24 weeks and receive 7 injections containing either the Hepatitis B vaccine or a placebo . All participants received $ 10 at each weekly visit ( maximum of $ 240 ) . Those r and omly assigned to the incentive program received additional monetary payments on an escalating schedule for attendance at weekly monitoring and vaccination visits with maximum possible earnings of $ 751 . Group attendance diverged after study week 8 with attendance better sustained in the incentive than control group ( group by time interaction , p=.035 ) . Overall percent of weekly sessions attended was 82 % for incentive versus 64 % for control ( p=.139 ) . Receiving all scheduled injections were 77 % of incentive versus 46 % of control participants ( p=.107 ) . A significantly larger percentage ( 74 % versus 51 % ; p=.016 ) of injections were received by incentive versus control participants on the originally scheduled day . Results suggest that monetary incentives can successfully motivate drug users to attend sessions regularly and to receive injected medications in a more reliable and timely manner than may be seen under usual care procedures . Thus , incentives may be useful for addressing adherence and allowing participants to reap the full benefits of newly developed medications
