A two-stage social network intervention for reducing alcohol and other drug use in residential colleges : Protocol for a feasibility trial

Background: In many countries, the rate of binge drinking and alcohol-related harms among students living in residential colleges exceeds that observed among young people in the general population. Peer influence plays a key role in driving alcohol and other drug (AOD) use in colleges. This highlights the potential role of peer influence AOD-interventions in college student-networks. This protocol paper outlines the design of a two-stage social network intervention (SNI) for reducing AOD-use in four Australian first-year residential college networks. Methods: In Stage 1, a peer-led workshop will provide education about AOD-use and harm-minimisation strategies to four first-year cohorts in the first week of semester one (N ~ 500). In Stage 2, a targeted SNI will be delivered to the largest co-educational, first-year cohort (N ~ 160), wherein heavy drinking 'Strategic Players' (influential students) will be identified and offered a brief, telephone-delivered motivational interviewing intervention for AOD-use (QuikFix). Participants will complete online surveys at baseline and 12-, 26-, and 52- weeks follow-up. Results: Recruitment occurred in February 2021 and is now closed. Results are expected to be submitted for publication in late 2022. Conclusions: This protocol paper outlines the design of a feasibility trial exploring the impact of applied SNIs for reducing AOD-use and related consequences in residential college student networks. If effective, the two-stage SNI proposed could (i) reduce AOD-use and risk of harm across first-year student networks and (ii) provide an effective brief intervention (QuikFix) to high-risk drinkers who have greatest potential to spread the intervention effects to other risky drinkers in their network.

A Longitudinal Assessment of Substance Use Treatment during the COVID-19 Pandemic Using Staff and Service Data

Introduction: Alcohol and other drug (AOD) treatment services were required to rapidly adapt delivery of care in response to the coronavirus (COVID-19) pandemic. This study examined longitudinal changes in the delivery of AOD counselling in Australia over 21 months (October 2019–July 2021) before and throughout the pandemic, using both staff self-report and service data. Methods: Treatment staff from a large AOD service in Queensland, Australia provided self-report data on time spent delivering counselling via face-to-face, outreach (home visits), telephone, and virtual (video) formats. Two waves of online questionnaires were collected, with staff reporting on their time before the pandemic (retrospectively for October 2019–February 2020); during the first lockdown period (retrospectively for March–May 2020); when restrictions were initially eased (June–September 2020); and one year later (July 2021). Service records of the number of counselling episodes conducted by each treatment modality were extracted between October 2019 and July 2021, and analysed by month. Results: Staff (n = 117) and service records indicated an increase in telephone-delivered AOD counselling during the first lockdown, alongside an increase in total counselling records. Telephone-delivered counselling was still significantly higher one year later. Face-to-face counselling declined after the onset of the pandemic, but increased quickly when restrictions were eased. Outreach counselling decreased during the first lockdown. Virtual counselling remained negligible throughout. Conclusion: AOD treatment services quickly utilised telephone counselling options at the start of the pandemic, and demonstrated continued utilisation of this method one year later. Increased virtual (video) counselling was not observed and may be due to limited infrastructure, staff training, and clients lacking Internet connectivity or technology required

Retrospective Self-Reports of How Adolescent Substance Use Changed with the COVID-19 Pandemic

The final year of high school is a challenging phase of adolescents’ lives and substance use can play an important role. We examined changes in the frequency and quantity of alcohol and cannabis use, and demographic correlates among Grade 12 students of 2020. Students (N = 844) from nine schools retrospectively self-reported changes in substance use after the easing of COVID-19 lockdowns (back to school), compared to before the pandemic. Changes in use were examined with age, gender, Aboriginal or Torres Islander, parental and family characteristics, and truancy. Thirty-one percent of students reported that they used alcohol less frequently, and 24% reported that they used it more frequently compared to pre-COVID-19. Most students (46%) reported that they used cannabis less, while a subset reported using more frequently (22%). A history of truancy was associated with an increased frequency (OR = 2.13 [1.18–3.83]) of cannabis use. A substantial minority of adolescents used more alcohol and cannabis after the initial COVID-19 lockdown period. Students in their final year who reported increased use may benefit from increased support to manage their substance use.</p

E-Cigarette Use Among High School Students-a Cross-Sectional Study of Associated Risk Factors for the Use of Flavour-Only and Nicotine Vapes

The aim of this study is to examine e-cigarette use among high school students and the associated risk factors for the use of flavour-only or nicotine vapes. Grade 12 students (N = 855) of 2020 from nine Australian schools completed a cross-sectional self-report survey. Correlates examined included age, gender, Aboriginal or Torres Strait Islander, parental and family characteristics, truancy, mental health (depression and anxiety), alcohol use and cigarette smoking. Overall, 74% reported that they had never used an e-cigarette or vaped, 12.5% had for flavour-only, and 13.5% had for nicotine vapes. Multinomial adjusted logistic regressions showed that males and teens reporting frequent alcohol or cigarette use had higher odds of vaping. In adolescents who had used an e-cigarette, half had used a nicotine vape. Those who engaged in risky drinking and smoked cigarettes were most likely to also use e-cigarettes, implying that this may be a high-risk group.</p
