Plain English Summary
Background and study aims
Drinking harmful amounts of alcohol can damage a person’s health and can lead to both social and economic costs. The Swedish National Alcohol Helpline provides telephone counselling to people that indulge in harmful and hazardous drinking who wish to change their drinking habits. The main aim of this study is to compare the effect of the current telephone counselling provided by the helpline, based on Motivational Interviewing techniques (treatment as usual), with a treatment based on self-help material and proactive follow-up counselling.
Who can participate?
Adults (aged at least 18) calling the Swedish National Alcohol Helpline for the first time in order to receive support to change their alcohol drinking habits
What does the study involve?
Participants are randomly allocated to one of two groups. Those in group 1 receive counselling currently offered by the Swedish National Alcohol Helpline (treatment as usual). The counselling is delivered according to each participants preference and involves Motivational interviewing and Cognitive Behavioural Therapy. Participants in group 2 are given a self-help booklet with information and exercises to help them change their alcohol drinking habits, followed by one session via telephone by a counsellor from the Helpline. All participants are assessed for their alcohol drinking habits and other health related statuses by telephone interview at the beginning of the study, as well as six and twelve months later.
What are the possible benefits and risks of participating?
Changes in alcohol drinking habits is very likely to lead to improvements in health and well-being. There is no risk of direct physical harm to participating in this study.

Acronym
AlC_HL
Study hypothesis
Current hypothesis as of 10/05/2017:
An alternative, partly proactive counselling model complemented by self-help material is more effective than the current on-demand counselling model in promoting change in a client’s alcohol drinking habits, measured by shift to lower AUDIT risk levels 6 and 12 months after the initial contact.
Previous hypothesis:
An alternative, partly proactive counselling model complemented by self-help material is as effective as the current on-demand model in promoting change in a client's alcohol drinking habits, measured by AUDIT scores 6 and 12 months after the initial contact.

Condition
Hazardous and harmful alcohol use
Intervention
Participants are randomly allocated to one of two treatments:
1. The Alcohol Helpline’s free-of-charge telephone service (treatment as usual) designed to provide support to persons whose alcohol-related problems are moderate to severe. The current counselling is based on Motivational Interviewing (MI) combined with elements of Cognitive Behaviour Therapy and is adapted to the severity of the problems and to the changes that the client is ready to adopt. In practice, the intervention for a specific individual may consist of a varying number of client-activated (reactive) and/or counsellor-activated (proactive) sessions according to the client’s preference.
2. The alternative counselling model which includes the delivery of self-help booklet followed by a proactive call where the Helpline counsellor monitors the client’s progress and use of the material. The material is designed as a guide to the change of alcohol use patterns.
