Plain English Summary

Background and study aims
We are conducting an adaptation of a family and social network intervention shown to be effective in helping adults experiencing alcohol and drug problems to be implemented with young people with alcohol and drug problems and tested in a small pilot study. Previous research has shown that the family has a considerable impact on young people’s drinking and drug use. Interventions involving the family and wider social networks have shown promise in helping young people to deal with substance abuse problems. At present there is limited delivery of family interventions for young people with alcohol and drug problems in routine practice in the UK. The study will adapt and further develop the Social Behaviour and Network Therapy (SBNT) approach that has been shown to be effective and cost-effective with adults with alcohol problems. This study will test feasibility of delivery and preliminary outcomes.

Who can participate?
Young people (aged between 12 and 18) with drug and/or alcohol problems

What does the study involve?
Participants will be randomly allocated to receive the adapted SBNT approach or existing treatment as usual that is not family-focused. Half of those participating (N=30) will receive the adapted intervention and the remaining half treatment as usual. The family-based intervention will be adapted to support young people aged 12-18. Following consultation with young people who had experience of alcohol and drug problem services and their carers, we will adapt the family and social approach. The intervention will then be tested in a small pilot study in routine young people services in Birmingham and Newcastle. Once this intervention is adapted and produced in manual form, a selection of therapists delivering treatment for young people in those services will be trained and supervised to deliver this adapted treatment. The family and social intervention (SBNT) will consist of 6 meetings with the young person with the alcohol or drug problem and their close family members or friends that they wish to involve. Treatment as usual will consist of what is normally delivered in those services. Those receiving the intervention or the control treatment as usual will be assessed at the beginning of the study and 3 and 12 months later. The study will also measure other aspects that affect the young people, such as mental health, family factors, crime and the use of other services. The research team will assess whether the intervention reduces the use of these other services, and is therefore more cost-effective. The study will also help to inform a decision on whether to prepare for a larger study with more participants in the future.

What are the possible benefits and risks of participating?
If the intervention was shown to be successful, those receiving the adapted intervention will show some benefit. Those participants randomised to the treatment as usual will have an opportunity to receive the family intervention once the study is completed if they wish to do so. There should also be benefit for those young people receiving help for alcohol and drug problems in the future through the results informing practice. There are no anticipated risks of participating in this study.

Scientific title

Adaptation and feasibility study of a family and social network intervention for young people who misuse alcohol and drugs



Study hypothesis

Expressed in null form, the study hypothesis is that the Social and Family Intervention (Youth-Social Behaviour and Network Therapy) will be as effective and cost-effective as treatment as usual (TAU).

Alcohol and drug addiction


Each group will have 30 participants (N=30 allocated to Youth-Social Behaviour and Network Therapy and N=30 allocated to Treatment as Usual).

Young people randomised to SBNT will be offered 6, weekly, 50-minute SBNT sessions for a period of a maximum of 12 weeks. Treatment as usual in the clinical centres (Newcastle and Birmingham) which will provide the comparison to the trial intervention is broadly similar. The fundamental contrast between the two treatments under study is that the trial intervention will have a family and social network focus and the treatment as usual will be individually focused. Young people randomised to receive treatment as usual will receive a similar number of individual sessions i.e.6 over a period of 12 weeks. Participants will then be followed up 3 and 12 months after baseline assessment.

Primary outcome measure

The primary outcome measure for the pilot trial will be based on the Timeline Follow-Back (TLFB) interview and will be the proportion of days on which the main problem substance was used in the preceding 90 day period covered by each assessment point. The main problem substance will be that for which the referral to the services was made and this will be corroborated at the research assessment interview prior to completion of the TLFB.

Secondary outcome measures

Family-based approaches have the potential to impact on other facets of young people's lives and may lead to changes in a number of secondary areas including, family, psychological and social outcome variables that will be measured with validated questionnaires that have been widely used in trials of young people: The following measures will be used.
1. Emotional well-being: The Strengths and Difficulties Questionnaire (SDQ) (Goodman, 1997) has five separate sub-scales for different aspects of problems or behaviours: emotional problems, conduct/behaviour problems, inattention/hyperactivity, relationships with peers, and pro-socialbehaviour. The first four scales can be added together to produce a score for total difficulties.
2. Social Network Support: Given the emphasis on family and peer support of the intervention, the Important People Drug and Alcohol interview (IPDA) will be used in order to understand the influence of social support on treatment for substance misuse.
3. Family Environment: The Family Environment Scale (Moos and Moos, 1986) is designed to measure the atmosphere in the family household and will be used where appropriate to the circumstances of the participant. It is a 27-item measure and yields scores for family cohesion, free expression of emotion in the family and absence of open conflict.
4. Working Alliance Inventory (Horvath & Greenberg, 1989) will be administered at 3-month follow-up to the young people and also to the therapists delivering the intervention and treatment as usual. The questionnaire measures the perceived strength of the working alliance between therapists and their clients during therapy sessions.
5. School attendance and engagement, self-reported crime and health care and social services contact will be measured based on questionnaires used by the applicants in previous alcohol trials (UKATT Research Team, 2005; Coulton, 2009).
6. EQ-5DY (version of the EQ-5D validated with youth populations.
