People seeking support from social care are disproportionately affected by gambling-related harms (GRHs). However, there is not much research on which screening tools are suitable for use in social care settings. The authors conducted a scoping review to identify and summarize the screening tools currently in use. While many screening tools were identified by the review, the authors noted that most of them are not suitable for use in social care settings. There is also little research on screening tools for affected others. Many of the screening tools assess problem gambling symptoms, not GRHs. Therefore, there is a need for a single-item screening tool that can identify GRHs in social care settings in both people who gamble and affected others.
