An evaluation of a brief motivational intervention among young ecstasy and cocaine users: no effect on substance and alcohol use outcomes.

AIMS: To investigate whether a stimulant- and alcohol-focused brief motivational intervention induces positive behaviour change among young, regular users of MDMA ('ecstasy'), cocaine powder and crack cocaine. DESIGN AND MEASUREMENTS: A randomized trial of the intervention versus a control group who received written health risk information materials only. All participants completed a baseline self-assessment questionnaire before randomization. Outcome measures were self-reported period prevalence abstinence from ecstasy, cocaine powder and crack cocaine and the frequency and amount of stimulant and alcohol use in the previous 90 days, recorded at 6-month follow-up via self-completion questionnaire and personal interview. PARTICIPANTS AND SETTING: A total of 342 adolescent and young adult stimulant users (aged 16-22 years) were recruited and 87% were followed-up. The intervention was delivered by a team of 12 agency youth drug workers and two researchers at five locations in Greater London and south-east England. FINDINGS: There were no significant differences in abstinence for ecstasy, cocaine powder or crack cocaine use between the experimental and control groups. Contrasting follow-up with baseline self-reports, there were no between-group effects for changes in the frequency or amount of stimulant or alcohol use. Participant follow-up data suggested that the baseline assessment was a contributing factor in within-group behaviour change among experimental and control condition participants. CONCLUSIONS: Our brief motivational intervention was no more effective at inducing behaviour change than the provision of information alone. We hypothesize that research recruitment, baseline self-assessment and contact with study personnel are influences that induce positive reactive effects on stimulant use.

Alcohol use by young people from different ethnic groups: consumption, intoxication and negative consequences.

OBJECTIVE: To investigate alcohol consumption among mid-adolescents from different ethnic groups and explore overall and gender variations in drinking behaviours. METHODS: A survey of alcohol use by 609 14-16 year olds recruited from three schools in an ethnically diverse area of London. Approximately 70% of the sample was of white English, white Irish, black Caribbean or black African ethnic origin. Self-report information was collected via a researcher-administered structured interview. RESULTS: There was a significantly lower prevalence of lifetime alcohol use among black African respondents than among the other three ethnic groups. Black African males and males and females from the two white ethnic groups reported drinking above levels recommended by the English Department of Health. Among the recent drinkers, over half of the white Irish and white English groups and over a quarter of black Caribbean and black African groups had been intoxicated in the 90 days before interview. Approximately three quarters of the white English and white Irish recent drinkers, but only a half of black Caribbean and black African recent drinkers had experienced a negative drinking-related consequence during the last year. CONCLUSIONS: The survey findings suggest that while young people of white English or white Irish ethnic origin from the populations studied are more likely to drink excessively and experience negative consequences from their drinking than black African and black Caribbean youth, a substantial minority of black African and black Caribbean youth also experience alcohol-related problems.

Relationship between prescribing and risk of opiate overdose among drug users in and out of maintenance treatment.

Opiate users (n = 135) from southern England, Glasgow and Edinburgh were interviewed about opiate overdose (lifetime). Fifty-six percent had overdosed. The majority (66%) reported mixing opiates with at least one other drug (mainly alcohol and/or benzodiazepines) at their last overdose. Patients identified misjudgements of purity, mixing drugs and misjudgements of tolerance as causes of overdose. The sample was divided into groups: (1) 'no prescription', (2) prescribed 'diazepam only', (3) prescribed 'methadone only' and (4) prescribed 'methadone + diazepam'. The 'methadone + diazepam' group reported more lifetime and deliberate overdoses, the 'methadone only' group were more likely to have used several drugs at the time of their last overdose and the 'no prescription' group to have used only heroin. Drug users' overdose risk may vary as a result of their prescribed and non-prescribed drug use. Interventions should be developed and tailored according to clients' needs and current use patterns.

Minimizing respondent attrition in longitudinal research: practical implications from a cohort study of adolescent drinking.

The methods used to maximize retention in a longitudinal study of adolescent drinking are discussed. Data were collected at three time points: at recruitment to the study, after nine months and at 18 months. Strategies to minimize attrition included the collection of detailed contact information, incentives for participation, postcard and telephone reminders and telephone interviews. Ninety-six percent of the original sample completed the first follow-up questionnaire, 92% completed the second and the study lost contact with just 3% of participants. The success of the current project is notable as this type of population is notoriously difficult to retain in longitudinal studies.

Prison based detoxification for opioid dependence: a randomised double blind controlled trial of lofexidine and methadone.

This paper reports results from the first controlled trial of opioid withdrawal treatment in the UK using lofexidine in a prison setting. Seventy-four opioid dependent male inmates at a Southern England prison were randomised to receive either methadone (the standard prison treatment) or lofexidine using a randomised double-blind design. No significant statistical difference between the treatment groups was found in relation to the primary variable of severity of withdrawal symptoms (effect size=0.12). No discernible difference was found in the sitting blood pressure or heart rate of the two groups during the trial. These results provide support for the use of lofexidine for the management of opioid detoxification in the prison setting.

Peer overdose resuscitation: multiple intervention strategies and time to response by drug users who witness overdose.

One hundred and thirty-five drug users in contact with treatment services in Scotland and England were interviewed about their experiences of witnessing overdoses - both overdoses resolved successfully and those leading to death - and actions taken to effect resuscitation. One hundred and four (77%) had witnessed a mean of 11.5 overdoses, of whom 41 (30.4% of the study sample) had witnessed an average of 4.2 fatal overdoses. A wide range of actions was reported at the most recent witnessed overdose, the most common being slapping or shaking the victim (an average of 2.5 minutes after overdose was first recognised) or walking the person around the room (3.2 minutes after recognizing overdose). There was no consistent relationship between the time taken to acting and the number of actions taken. Successful resolution of last witnessed overdose was associated more strongly with immediate onset of overdose, while those that led to death were more often those that involved slow onset of overdose. There is clear evidence of the opportunity and willingness of witnesses to intervene, particularly when overdose onset is immediate, with a wide range of strategies adopted to encourage recovery, although these may often be inappropriate and wrongly prioritized.
