Mental imagery and cocaine craving with John Marsden

Ep. 35

Rob Calder talks to Professor John Marsden about cocaine cravings. Professor Marsden discusses the lack of pharmacological treatments for cocaine, and about his recent study using mental imagery to address cocaine cravings. He talks about the benefits of positive imagery compared with negative imagery. He then discusses how useful mixed-methods research can be and the importance of writing up data from unfinished trials.

Brief interventions, emergency departments, and alcohol with Paolo Deluca

Season 1, Ep. 43
In this episode of the Addiction Audio podcast, Dr Paolo Deluca talks about his recent research on using brief interventions in emergency departments.The research involved a three-armed randomised controlled trial on brief interventions for young people, and found no significant differences in alcohol-related outcomes between young people who had been given a brief intervention and those who had not. In the podcast, Paolo reflects on some of the potential reasons for this, considering previous evidence in support of brief interventions.“When you move away from an efficacy trial or a single site study where you have highly trained professionals or practitioners delivering the interventions and you move into the real-world NHS setting is where you tend to lose some of the effectiveness you might have had in the early stages of the brief intervention.”Paolo also talks about the core components of brief interventions that can be delivered in 10 minutes in busy emergency departments, and discusses some of the logistical and ethical challenges of recruiting young people to a three-armed trial.“We involved 10 emergency departments, and we ran it for around 8 months and were recruiting from 10am to 10pm in the afternoon and we were covering 7 days a week. To achieve that we had essentially an army of researchers.”Original article: Effectiveness and cost-effectiveness of face-to-face and electronic brief interventions versus screening alone to reduce alcohol consumption among high risk adolescents presenting to Emergency Departments: three-arm pragmatic randomised trial (SIPS Junior High Risk Trial).
