Suicide is a leading cause of death among young adults. Additionally, research suggests suicidality and gambling severity may be related. In this study, the researchers analyzed data from a large longitudinal study in the United Kingdom. Participants consisted of youths (aged 16–24) who had gambled within the past year. They responded to the survey at both time points in 2019 (wave 1) and 2020 (wave 2). The researchers examined how changes in gambling severity might affect suicide attempts. The results suggest that increases in gambling severity over time are associated with increased risk of suicide attempts. These findings highlight that repeated screening for gambling harms should be included within relevant health and public service settings.
