Monitoring adherence and abstinence of cannabis use disorder patients: Profile identification and relationship with long-term treatment outcomes.

BACKGROUND: Patients with cannabis use disorder (CUD) show heterogeneous sociodemographic and consumption patterns. Although previous studies, focused on identifying subgroups of CUD patients using input variables, have yielded useful results for planning individualized treatments, no published research has analyzed the profiles of CUD patients according to their therapeutic progress. This study therefore aims to identify subgroups of patients using adherence and abstinence indicators and to explore whether these profiles are associated with sociodemographic characteristics, consumption variables, and long-term therapeutic outcomes. METHODS: This was a retrospective observational study with a multisite sample of 2055 CUD outpatients who were beginning treatment. The study monitored patient data at two-year follow-up. We conducted latent profiles analysis on the appointment attendance ratio and percentage of negative cannabis tests. RESULTS: A three profile solution emerged: i) moderate abstinence/moderate adherence (n = 997); ii) high abstinence/moderate adherence (n = 613); and iii) high abstinence/high adherence (n = 445). The study found the most marked differences at the beginning of treatment for education level (chi2 (8) = 121.70, p < .001), source of referral (chi2 (12) = 203.55, p < .001), and frequency of cannabis use (chi2 (10) = 232.39, p < .001). Eighty percent of patients from the "high abstinence/high adherence" group were relapse-free at two year follow-up. This percentage decreased to 24.3 % in the "moderate abstinence/moderate adherence" group. CONCLUSIONS: Research has shown adherence and abstinence indicators to be useful for identifying subgroups of patients with different prognoses regarding long-term success. Recognizing the sociodemographic and consumption variables associated with these profiles at the beginning of treatment could help to inform the design of more individualized interventions.

Incorporación del mindfulness en el aula: un estudio piloto con estudiantes universitarios / Mindfulness Classroom Implementation: A Pilot Study with University Students

Resumen El objetivo del estudio fue analizar los efectos de un programa breve de mindfulness adaptado al contexto del aula, en relación con el nivel de mindfulness (MAAS), evitación experiencial (AAQ-II), ansiedad (STAI) y satisfacción vital (SWLS). La muestra estuvo conformada por 115 estudiantes universitarios. Tras la participación en el programa, los estudiantes aumentaron significativamente los niveles de satisfacción vital y ansiedad estado, no se encontraron diferencias en el resto de variables. Sin embargo, el aumento de la satisfacción vital se relacionó con el aumento del nivel de mindfulness al final del programa (coincidiendo con el inicio de los exámenes). En conclusión, un programa breve de mindfulness mejora la satisfacción vital, aun en un período de alto nivel de ansiedad como es el periodo de exámenes.

Abstract The aim of this pilot study was to analyze the effects of a brief mindfulness program adapted to the academic context, to acknowledge the influence on the level of mindfulness (MAAS), experiential avoidance (AAQ-II), anxiety (STAI) and life satisfaction (SWLS). The sample consisted of 115 college students. After participating in the programme, students showed significantly higher levels of life satisfaction and state anxiety and no differences were found in mindfulness, experiential avoidance and trait anxiety. However, the increase in life satisfaction was related to the increased level of mindfulness at the end of the program (which concurred with the beginning of the exams). In conclusion, a brief mindfulness program improved life satisfaction even in a period of high anxiety, such as the exams period.
