Randomized controlled internal pilot trial of a diversion programme for adolescents in police custody who possess illicit substances.

BACKGROUND: Adolescents involved in criminal proceedings are significantly more likely to re-offend than a similar population diverted away from criminal justice. Adolescents who use substances and offend are at higher risk of experiencing negative social, psychological and physical problems that often persist into adulthood. There is some evidence that brief interventions combined with appropriate psychoeducation may be effective in reducing adolescent substance use. METHODS: Prospective two-armed, individually randomized internal pilot randomized controlled trial (RCT) with follow-up at 6 months. Young people across three police forces-Kent, Cornwall and Sefton-arrested in possession of class B or C illicit substances were randomly allocated to receive the ReFrame intervention or business as usual. In total, 102 participants were eligible of whom 76 consented and 73 were followed up at 6 months. Outcomes addressed offending behaviour, frequency of substance use, wellbeing and mental health. The study was conducted between February and December 2022. RESULTS: All progression criteria were met, 80% of those eligible consented, 96% adhered to their allocated treatment and 88% were followed up at the primary endpoint. CONCLUSIONS: The feasibility of conducting the pilot trial was a success and it will now proceed to a definitive RCT.

Evaluating police drug diversion in England: protocol for a realist evaluation.

There is increasing international interest in the use of police drug diversion schemes that offer people suspected of minor drug-related offences an educative or therapeutic intervention as an alternative to criminalisation. While there have been randomised trials of some such schemes for their effects on reducing offending, with generally positive results, less is known about the health outcomes, and what works, for whom, in what circumstances and why. This protocol reports on a realist evaluation of police drug diversion in England that has been coproduced by a team of academic, policing, health, and service user partners. The overall study design combines a qualitative assessment of the implementation, contexts, mechanisms, moderators and outcomes of schemes in Durham, Thames Valley and the West Midlands with a quantitative, quasi-experimental analysis of administrative data on the effects of being exposed to the presence of police drug diversion on reoffending and health outcomes. These will be supplemented with analysis of the cost-consequences of the evaluated schemes, an analysis of the equity of their implementation and effects, and a realist synthesis of the various findings from these different methods.

A multicomponent psychosocial intervention to reduce substance use by adolescents involved in the criminal justice system: the RISKIT-CJS RCT.

Background: Substance use and offending are related in the context of other disinhibitory behaviours. Adolescents involved in the criminal justice system constitute a particularly vulnerable group, with a propensity to engage in risky behaviour that has long-term impact on their future health and well-being. Previous research of the RISKIT programme provided evidence of a potential effect in reducing substance use and risky behaviour in adolescents. Objectives: To evaluate the clinical effectiveness and cost-effectiveness of a multicomponent psychosocial intervention compared with treatment as usual in reducing substance use for substance-using adolescents involved in the criminal justice system. Design: A mixed-methods, prospective, pragmatic, two-arm, randomised controlled trial with follow-up at 6 and 12 months post randomisation. Setting: The study was conducted across youth offending teams, pupil referral units and substance misuse teams across four areas of England (i.e. South East, London, North West, North East). Participants: Adolescents aged between 13 and 17 years (inclusive), recruited between September 2017 and June 2020. Interventions: Participants were randomised to treatment as usual or to treatment as usual in addition to the RISKIT-Criminal Justice System (RISKIT-CJS) programme. The RISKIT-CJS programme was a multicomponent intervention and consisted of two individual motivational interviews with a trained youth worker (lasting 45 minutes each) and two group sessions delivered over half a day on consecutive weeks. Main outcome measures: At 12 months, we assessed per cent days abstinent from substance use over the previous 28 days. Secondary outcome measures included well-being, motivational state, situational confidence, quality of life, resource use and fidelity of interventions delivered. Results: A total of 693 adolescents were assessed for eligibility, of whom 505 (73%) consented. Of these, 246 (49%) were allocated to the RISKIT-CJS intervention and 259 (51%) were allocated to treatment as usual only. At month 12, the overall follow-up rate was 57%: 55% in the RISKIT-CJS arm and 59% in the treatment-as-usual arm. At month 12, we observed an increase in per cent days abstinent from substances in both arms of the study, from 61% to 85%, but there was no evidence that the RISKIT-CJS intervention was superior to treatment as usual. A similar pattern was observed for secondary outcomes. The RISKIT-CJS intervention was not found to be any more cost-effective than treatment as usual. The qualitative research indicated that young people were positive about learning new skills and acquiring new knowledge. Although stakeholders considered the intervention worthwhile, they expressed concern that it came too late for the target population. Limitations: Our original aim to collect data on offences was thwarted by the onset of the COVID-19 pandemic, and this affected both the statistical and economic analyses. Although 214 (87%) of the 246 participants allocated to the RISKIT-CJS intervention attended at least one individual face-to-face session, 98 (40%) attended a group session and only 47 (19%) attended all elements of the intervention. Conclusions: The RISKIT-CJS intervention was no more clinically effective or cost-effective than treatment as usual in reducing substance use among adolescents involved in the criminal justice system. Future research: The RISKIT-CJS intervention was considered more acceptable, and adherence was higher, in pupil referral units and substance misuse teams than in youth offending teams. Stakeholders in youth offending teams thought that the intervention was too late in the trajectory for their population. Trial registration: This trial is registered as ISRCTN77037777.

We explored how useful a psychological intervention was in reducing substance use among young people who had some involvement in the criminal justice system. We recruited young people aged between 13 and 17 years in four areas of England (i.e. South East, London, North West and North East). Young people were recruited from youth offending teams, pupil referral units and substance misuse teams. Those young people who were willing to participate were offered usual treatment and half, chosen at random, were offered an opportunity to take part in the RISKIT-Criminal Justice System (RISKIT-CJS) programme. The RISKIT-CJS programme had four distinct parts. The first was a 1-hour session that used an approach called motivational interviewing to explore the young person's substance use and discuss different strategies to change their behaviour. This was followed by two group sessions delivered over 2 consecutive weeks. These group sessions addressed risks associated with substance use, what triggers use and the health and social consequences. In addition, young people were taught new skills to help them manage in situations in which they might normally use substances. At the end of the group sessions, the young people had another motivational interview. Twelve months after participants started, we found that the frequency of substance use had decreased in both groups; however, the RISKIT-CJS intervention was no better than treatment as usual. When we spoke with young people who had taken part and staff involved with this population, we got a mixed picture. In some settings, particularly pupil referral units, the RISKIT-CJS intervention was well received by young people and staff, and staff felt that it was a useful additional resource to the work that they were currently undertaking. On the other hand, in the youth offending teams, the staff thought that the programme was too different from their normal work to be implemented easily and they considered the population they work with too established in their substance use and criminal activity to benefit from the programme.

Pragmatic randomised controlled trial to evaluate the effectiveness and cost effectiveness of a multi-component intervention to reduce substance use and risk-taking behaviour in adolescents involved in the criminal justice system: A trial protocol (RISKIT-CJS).

BACKGROUND: Adolescence is a critical developmental stage when young people make lifestyle choices that have the potential to impact on their current and future health and social wellbeing. The relationship between substance use and criminal activity is complex but there is clear evidence that the prevalence of problematic substance use is far higher among adolescent offenders than the general adolescent population. Adolescent offenders are a marginalized and vulnerable population who are significantly more likely to experience health and social inequalities in later life than their non-offending peers. There is a paucity of evidence on effective interventions to address substance use and risk-taking behaviours in adolescent offender populations but it is clear that preventative or abstinence orientated interventions are not effective. RISKIT-CJS is an intervention developed in collaboration with young people taking account of the current best evidence. Feasibility and pilot studies have found the intervention addresses the needs of adolescents, is acceptable and has demonstrated potential in reducing substance use and risk-taking behavior. METHODS: The study is a mixed method, two-armed, prospective, pragmatic randomized controlled trial with individual randomisation to either treatment as usual alone or the RISKIT-CJS intervention in addition to treatment as usual. Adolescents, aged 13 to 17 years inclusive, engaged with the criminal justice system who are identified as having problematic substance use are eligible to participate. The study will be conducted across three geographical areas; South and South East England, London and North East England between March 2017 and February 2019. DISCUSSION: The study represents an ambitious programme of work to address an area of need for a marginalized and vulnerable population. TRIAL REGISTRATION: ISRCTN77037777 registered 15/09/2016.

Multicentre individual randomised controlled trial of screening and brief alcohol intervention to prevent risky drinking in young people aged 14-15 in a high school setting (SIPS JR-HIGH): study protocol.

INTRODUCTION: Drinking has adverse impacts on health, well-being, education and social outcomes for adolescents. Adolescents in England are among the heaviest drinkers in Europe. Recently, the proportion of adolescents who drink alcohol has fallen, although consumption among those who do drink has actually increased. This trial seeks to investigate how effective and efficient an alcohol brief intervention is with 11-15 years olds to encourage lower alcohol consumption. METHODS AND ANALYSIS: This is an individually randomised two-armed trial incorporating a control arm of usual school-based practice and a leaflet on a healthy lifestyle (excl. alcohol), and an intervention arm that combines usual practice with a 30 min brief intervention delivered by school learning mentors and a leaflet on alcohol. At least 30 schools will be recruited from four regions in England (North East, North West, London, Kent and Medway) to follow-up 235 per arm. The primary outcome is total alcohol consumed in the last 28 days, using the 28 day Timeline Follow Back questionnaire measured at the 12-month follow-up. The analysis of the intervention will consider effectiveness and cost-effectiveness. A qualitative study will explore, via 1:1 in-depth interviews with (n=80) parents, young people and school staff, intervention experience, intervention fidelity and acceptability issues, using thematic narrative synthesis to report qualitative data. ETHICS AND DISSEMINATION: Ethical approval was granted by Teesside University. Dissemination plans include academic publications, conference presentations, disseminating to local and national education departments and the wider public health community, including via Fuse, and engaging with school staff and young people to comment on whether and how the project can be improved.
