In Spain offering families of secondary school children a low-value voucher to come to family-based prevention sessions greatly improved attendance even after the vouchers were discontinued.

Summary Poor participation rates represent one of the most serious problems facing family-based drug use prevention programs. Strategies involving incentives have been used to increase recruitment and retention of the target population of such interventions, but in Spain, such strategies for modifying behaviour are unusual. The goal of the research was to study the use of small financial incentives (10 Euro voucher) as a strategy to increase attendance and reduce dropout in a family drug-prevention program applied in the school context. Participants were 211 pupils (aged 12–13) and their parents. The results show that small financial incentives can be useful to increase the attendance of families in prevention programs and to reduce dropout.
