Gambling disorder (persistent/recurrent gambling) can be harmful to health/social wellbeing. Previous research suggests that stressful life events, such as child maltreatment increase likelihood of gambling disorder. However, these studies rely on young adults remembering if stressful life events that happened long ago, rather than asking about these events close to when they happened. We also do not know much about the influence of other types of Adverse Childhood Experiences (e.g. parental mental health problems). We plan to look at the influence of a range of Adverse Childhood Experiences on gambling disorder, using data that have followed individuals up regularly since birth until their 30's.
