Background and study aims
Depending on how the problem is defined, between 5-20% of all Swedish children grow up with parents who have alcohol problems, which may affect the children negatively. Nine out of ten Swedish municipalities therefore provide resources for support, but less than 2% of these children are reached by this support. Delivering support programs via the internet is a promising strategy. However, web-based programs targeting this at-risk group of children are scarce. Previously, the study team developed a 1.5 hour long web-based self-help program (Alcohol & Coping) which appears to be an effective way to control the adolescent’s own alcohol consumption. However, there is a need for a more intense program, and therefore Kopstoring, a comprehensive Dutch psycho-educative (education for people with mental health problems) prevention program, has been adapted to fit the Swedish context. The purpose of the program, in Swedish called Grubbel, is to strengthen protective factors, such as coping skills and mental well-being, prevent the development of mental health disorders, and to reduce alcohol consumption. The aim of this study is to evaluate the effectiveness of Grubbel, at improving coping strategies, mental health status and substance use.

Who can participate?
15-25 year olds who have at least one parent with a substance use problem and/or mental illness.

What does the study involve?
Participants are randomly allocated to one of two study groups. Those in the first group take part in Grubbel. This involves eight weekly online chat meetings lasting for 1.5 hours each, with a final follow up meeting in the ninth week. Each session fosuses on different themes: (1) getting acquainted with the home situation, (2) roles in the family, (3) thoughts and feelings, (4) questions and answers about mental health problems, risky alcohol use, addiction, and heredity, (5) different behaviour patterns, (6) social networks, (7) leading your own life with regards to social networks, and (8) the future. Between each session, participants complete a homework assignment which is discussed in the following session. Each session is moderated by two trained professionals who have experience working with young people. Those in the second group continue as normal for the duration of the study. At the start of the study and then after 6, 12 and 24 months, participants in both groups complete a number of questionnaires in order to assess their mental health status, alcohol consumption and life satisfaction.

What are the possible benefits and risks of participating?
Participants who receive Grubbel may benefit from improved coping skills and mental wellbeing, which could help prevent them from developing mental health conditions or drinking too much alcohol. There are no notable risks involved with participating in the study.

Where is the study run from?
The study is run from STAD, Centre for Psychiatry Research, Karolinska Institutet & Stockholm Health Care Services and takes place online (Sweden)

When is study starting and how long is it expected to run for?
April 2016 to December 2018

InterventionParticipants are randomly allocated into the intervention Grubbel or a control group using an unequal allocation ratio of 1:8. An unrestricted random allocation sequence will be used.

Intervention group: The intervention program Grubbel is a manual-based and well-structured prevention program and consists of eight consecutive weekly online chat-meetings, each meeting lasting 1.5 hours, and a ninth follow-up meeting one week after the last meeting. Each session focus on a particular theme:
1. Getting acquainted with the home situation
2. Roles in the family
3. Thoughts and feelings,
4. Questions and answers about mental health problems, risky alcohol use, addiction, and heredity
5. Different behaviour patterns
6. Social network
7. Leading your own life with regards to social networks
8. The future.
The ninth session is a follow-up session. In between each session, the participants are required to complete a homework assignment that is discussed at the following session. Each meeting is moderated by one or two trained professionals (prevention and social workers, and psychologists from mental health and addiction centres) who have previous experience from working with the target group, and has participated in a two-day Grubbel-course held by our research group.

Control group: Participants receive care as usual for the duration of the study, which involves receiving information about where to find care as usual.

All assessment are conducted using web-based questionnaires reached by hyperlinks sent out to the participants via e-mail. The assessment consists of a baseline measurement (T0) which takes place before randomization and three follow-up measurements after 6 (T1), 12 (T2), and 24 (T3) months.
Intervention typeBehavioural
Primary outcome measure1. Depressive symptoms during the past week are measured using the Center for Epidemiological Studies Depression Scale for children (CES-DC) at baseline, 6, 12 and 24 months
2. Coping strategies are measured using the Brief COPE at baseline, 6, 12 and 24 months
3. Quality of life is measured using the World Health Organization’s Quality of Life Questionnaire (WHOQOL-BREF) at baseline, 6, 12 and 24 months
4. Alcohol consumption is assessed using the short version of the Alcohol Use Disorders Identification Test (AUDIT-C) at baseline, 6, 12 and 24 months
Secondary outcome measures1. Overall life satisfaction is measured using the Ladder of Life, asking about the participants’ past, present, and future rating of his/her life over a one year perspective at baseline, 6, 12 and 24 months
2. Competencies and behavioural problems are measured using the young person’s version of the Youth Self Report List (YSR), which consists of 119 problem behaviour items that form internalizing and externalizing scales at baseline, 6, 12 and 24 months
