IntroductionDepression has generally been found to be associated with heavy drinking and alcohol use disorders [1][2][3][4]. There is also evidence of a link between anxiety and extensive use of alcohol [5][6][7][8], but this association has been less extensively scrutinized and the findings seem less clear. Thus, some studies of young people report null-findings [9] or a link between anxiety and heavy drinking that is attributable to concurrent symptoms of depression and/or other confounding factors [10][11][12].The bulk of previous studies focus on severe forms of internalizing problems and harmful drinking, and have typically relied on diagnoses or other dichotomous measures. Obviously, such research may be of clinical significance, yet the findings do not necessarily apply to mild forms of emotional distress and non-pathological drinking [13]. To address subclinical conditions is important in its own right, not least because they may contribute to the total burden of harm and social cost at least as much as the clinical ones -simply by being far more prevalent.Furthermore, studies of adult samples predominate in the field, and the association between emotional distress and heavy drinking may be different among young people. The onset of drinking typically occurs in adolescence, and the consumption of alcohol and related harm escalate during the late teens and reaches a peak in early adulthood [14,15]. Problems related to mood and emotions also tend to increase in this period of life [16]. Moreover, it has been hypothesized that risk factors related to mental health may become increasingly important in influencing drinking behaviour as individuals approach adulthood, reflecting the challenges of leaving a protected environment, and entering an independent adult role [17].Indeed, a recent study showed that the association between depression and alcohol use disorders was stronger in early adulthood than in adolescence [18]. The present paper pursues this issue further by analysing four-wave panel data on less severe forms of emotional distress and heavy drinking from a general population study of young people.
