Effects of voucher-based intervention on abstinence and retention in an outpatient treatment for cocaine addiction: a randomized controlled trial.

The aims of this study were to assess whether voucher magnitude improved cocaine abstinence and retention in an outpatient treatment for cocaine dependence, and to determine the effectiveness of a contingency management intervention in a European cultural context. A randomized controlled trial was conducted in which 96 participants who were randomly assigned to 1 of 3 treatment conditions in a community setting: standard outpatient treatment, community reinforcement approach (CRA) plus low monetary value vouchers (each point earned was equivalent to 0.125 Euro, US

0.36). In the standard treatment group, mean percentage of cocaine-negative samples was 88.45%, versus 96.09% in the CRA plus low-vouchers group, and 97.07% in the CRA plus high-vouchers group. Retention rate at 6 months was 36.5% in the standard treatment group, 53.3% in the CRA plus low-vouchers group, and 69.0% in the CRA plus high-vouchers group. The CRA plus vouchers groups obtained better results than the standard program. This study showed that treating cocaine addiction by combining CRA with vouchers was more effective than standard treatment in community outpatient programs in Spain.

Construcción y validación de un cuestionario de factores de riesgo interpersonales para el consumo de drogas en la adolescencia

Low participation rates constitute a serious problem faced by family drug abuse prevention programs. In this study we analyse the factors related to participation in a Life Skills Training program implemented in three schools in Spain. Participants in the study were 485 pupils aged 12 - 14 years and their respective parents. The variables that predicted participation in the program were: number of children and educational level of parents, childrens drug use, family conflict, parental rearing style, relationships between parents and children and family communication. The results from Spain are similar to those found in international studies, and indicate that the families most at risk of drug use are those least likely to participate in prevention programs. There is a need for strategies to increase participation in prevention programs of the families most at risk.

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 behavior are unusual. The goal of the research was to study the use of small financial incentives (€10 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.
