Gambling problems can have severe personal consequences, including financial hardship, emotional difficulties, social impacts, employment difficulties and legal problems. They can also have significant impacts on families and communities. It has been estimated that the gambling problem of on Australian negatively affects at least seven other people (Productivity Commission, 1999). The impact of gambling problems on families has received relatively little research attention. Although most available information is based on intimate partners and children, gambling problems can also affect extended family members such as parents, grandparents and siblings (Dowling, Rodda, Lubman & Jackson, 2014).
