This is a scoping review about adult children of parents with alcohol abuse based on ten articles published by researchers. The aim of this study was to examine the impact of parental alcohol addiction on adult children's psychological well-being and health, and to identify what support and interventions society can offer to improve the situation of adult children in families where at least one parent has alcohol addiction. To identify and analyse patterns and themes, I conducted a thematic analysis. In the thematic analysis, I found themes that touched on attachment and role reversal, the role of communication and its effects on children, and help and social interventions. The result showed that alcohol abuse doesn’t only affect the individual with the illness but also the people around them; such as their kids. Relatives of people with alcohol abuse have the right to get help from society. Many adults who have had difficulties with attachment need motivation to break the pattern so as not to pass on their patterns and behaviours to the next generation. The adult children have experienced parents' denial of their addiction, dysfunctional communication and insecure attachment, which has led to negative and faulty self-perception and self-esteem. Other emotions such as worry, sadness and anger also appear in the results. The result of the scoping review showed that parents' support and openness about their addiction to the adult children is important. The support is needed to help the children develop resilience and to promote well-being, development and self-esteem. That interventions and support from society can help individuals develop strategies to focus on their own well-being and avoid passing on negative behaviour patterns to their children.
