Voucher-based contingency management (CM) effectively improves treatment retention and abstinence for cocaine and nicotine use disorders in Spain. Further research is needed to confirm its efficacy for cannabis use disorders.
Area of Science:
- Addiction Medicine
- Behavioral Psychology
- Public Health
Background:
- Contingency management (CM) is an evidence-based behavioral intervention for substance use disorders (SUDs).
- Voucher-based CM utilizes incentives to reinforce positive behaviors like treatment attendance and abstinence.
- The adoption and effectiveness of CM in Spain for various SUDs require evaluation.
Purpose of the Study:
- To review published studies on voucher-based CM for cocaine, nicotine, and cannabis use disorders in Spain.
- To discuss the effectiveness, challenges, and future directions of CM in Spanish clinical settings.
Main Methods:
- A narrative review of studies published between 2008 and 2015.
- Included studies evaluated incentives for SUD treatment in Spain with control or comparison groups.
Main Results:
- Voucher-based CM improved treatment retention and cocaine abstinence compared to standard care.
- CM enhanced psychosocial functioning in cocaine-dependent individuals.
- CM addition to CBT improved smoking cessation rates.
- Data on CM for cannabis use disorders in youth were insufficient to confirm efficacy.
Conclusions:
- CM effectiveness for cocaine and nicotine dependence in Spain is supported by research, aligning with US findings.
- CM has not been widely adopted in Spanish clinical practice.
- Limited data hinder confirmation of CM efficacy for cannabis use disorders; more research is needed.
