JITAIs and using smartphones to prevent lapse with Olga Perskie

Ep. 36

Rob Calder talks to Dr Olga Perski about her recent research on just-in-time adaptive interventions (JITAIs) whereby smartphones are used to help prevent lapses among people who are trying to quit or reduce alcohol, tobacco or other drug use. Dr Perski talks about why the literature is so complex and how defining JITAIs is difficult in the first place. She talks about the potential for Ecological Momentary Assessment (EMA), GPS positioning and micro-randomised trial studies to contribute in this area, and how we may not want to press ahead with full-scale RCTs before having conducted additional conceptual and computational work to clarify what JITAIs are and how to develop them. Dr Perski also discusses the challenges of regulating mobile health apps so that people can access apps based on evidence of effectiveness. This episode was recorded online on 30 September 2021.

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).
