The most common type of alcohol dependence, with late onset and without antisocial behaviour, is defined as type 1 alcoholism. By use of established methods the project will study men and women with type 1 alcohol-dependence. Psychosocial, psychological and neurobiological risk factors are investigated and to what extent these risk factors interact. Furthermore, strategies of treatments, especially cognitive behavioural therapy in combination with pharmacological treatment, will be studied. In addition, we will investigate whether the risk factors can predict treatment outcome and relapse. Since individuals with type 1 alcoholism are relatively unknown by the social service and addiction treatment units/health care system, increased knowledge of this common type of alcoholism is necessary to improve identification of this specific type of dependence, conceptualise new treatment strategies and develop tools for prevention.
