Gambling is linked to harmful consequences. One serious harm is suicide. The researchers reviewed qualitative studies on gambling-related suicide and suicidality (e.g., interviews and case reports). They aimed to identify the role of gambling in suicidality. A total of 20 academic, peer-reviewed qualitative papers were reviewed. Gambling was found to be related to suicidal behaviour through (1) indebtedness and (2) shame. Suicide was also found to be related to mental health conditions, personality traits, and difficult life conditions. But these factors might also appear as a result from gambling. In some cases, treatment was effective to prevent suicidality. But indebtedness and shame might prevent people from seeking help.
