RESUMEN
Background: When addressing antisocial behaviour among adolescents, programs based on the paradigm of positive psychology through enhancing self-efficacy have demonstrated their effectiveness in furthering the positive development of young people with a history of antisocial behaviour. Nevertheless, there has been little research into the effectiveness of these type of programs in mitigating substance abuse among juvenile offenders. The aim of this paper is to analyse the effectiveness of a contingency management program in reducing the prevalence of relapses into drug consumption among adolescents who have committed serious crimes. Methods: The study consisted of a sample of 91 male adolescents, between 15 and 19 years, in juvenile detention, who were divided into two treatment groups. For both groups, biological testing was used to detect drug consumption upon their re-turn from leave permits from the Centre. Results: The quasi-experimental group had significantly lower rates of relapse than the quasi-control group. Furthermore, being part of the quasi-experimental group was a significant predictor of reduced rates of relapses. Conclusion: The results suggest that the incorporation of treatment strategies which reinforce feelings of self-efficacy and adequate orientation towards the future, as a complement to disciplinary sanctions, are effective in reducing relapses in drug use among adolescent offenders.
RESUMEN
One of the factors that increase the likelihood of adolescents starting to exhibit and consolidate anti-social behavior is drug use, with a consistent pattern of consumption of different substance found in young offenders (Aebi, Bessler & Steinhausen, 2021). A cognitive-behavioral group treatment program inspired by the positive psychology approach was developed and applied to drug use in minors deprived of liberty (experimental group); the results were compared to those of a group of adolescents with the same type of drug use in the same center (active control group) at two points in time: during and after incarceration. The fall in the rate of problems associated with drug use after incarceration in the experimental group was statistically significant compared to the control group, and the effect size of the experimental condition was large (á¿^2 = 0.55), much higher than the control group (á¿^2 = 0.16). The treatment program has proven to be an effective tool for reducing problems associated with drug use and is especially effective in reducing alcohol and cannabis consumption.
Uno de los factores que aumentan en mayor medida la probabilidad de que los adolescentes inicien y consoliden comportamientos antisociales es el consumo de drogas, encontrándose un patrón consistente de consumo de diferentes sustancias en los menores infractores (Aebi, Bessler y Steinhausen, 2021). Para la redacción del presente trabajo se desarrolló y aplicó un programa de tratamiento, de corte cognitivo conductual e inspirado en el enfoque de la psicología positiva, para el consumo de drogas en menores de edad privados de libertad (grupo experimental). Los resultados se compararon con los de un grupo de adolescentes con la misma tipología de consumo internos en el mismo Centro (grupo control activo) en dos momentos, durante y tras el internamiento. El grupo experimental redujo de manera estadísticamente significativa la tasa de problemas asociados al consumo de drogas en comparación con el grupo control tras el internamiento, siendo el tamaño del efecto de la condición experimental elevado (á¿
