The report focused specifically on harms inflicted by the problematic consumption of alcohol on members of the family, particularly spouses and children, and on the functioning of the family unit as a whole. The key objectives of this report were to (a) improve understanding of the nature and extent of the impacts, (b) provide specific directions for future research, and (c) identify salient factors to be incorporated in national health policies, and prevention and treatment initiatives that aim to reduce the burden of alcohol use disorders in Australia. It is important to note that the review is not all-inclusive. The impacts that were considered most important and the ones for which there was considerable empirical support were selected for review. The review relied on cross-sectional studies when more rigorous longitudinal studies were not available. Much of the research has been conducted internationally; however, where available, findings from large-scale cohort studies in Australia and New Zealand have been included to improve understanding of the links between parental alcohol use problems and family functioning within the local context. The report also overviewed the available research on the impact of alcohol within Indigenous communities in Australia. The review demonstrated that there is a large body of research showing significant associations between parental alcohol use disorders and a range of problems in family life and functioning. These problems include, but are not limited to, parent and family conflict and violence, parental separation and divorce, parent mental health and other substance use problems, economic problems, disrupted
