This study explored the ability of the general population in Singapore to recognize gambling disorder (GD) and stigma associated with GD. Participants were 595 adults who were presented with a vignette that described a person experiencing problem gambling. Most participants correctly identified the condition as GD. They most often recommended informal, non‑medical, and community resources for help-seeking. Many believed that people with GD can fully recover with appropriate support, although there is a chance of relapse. Most participants believed that not seeking help would worsen the condition. Stigma towards GD was common and was higher among older adults, Malay and Indian participants, those who were married, and those who knew someone with similar problems. The findings can inform public health efforts to reduce stigma and improve support for people with GD.
