This scoping review examined 38 studies from different settings around the world to understand how well mental health screening tools work. The researchers looked at tools used to detect mental disorders in individuals struggling with mental health issues. They analyzed how sensitive and specific these tools are, how easy they are to use, and what resources they require.
The results showed that diagnostic performance varies significantly by tool. For example, the Posttraumatic Symptoms Scale (PTSS-10) showed 98% diagnostic performance, while the AC-OK tool showed 96%. In contrast, the Adolescent Psychotic-Like Symptom Screener (APSS) showed 68% diagnostic performance. Overall, the tools were generally effective, but their success depends on the specific population and setting.
Important limitations were noted. The studies had inconsistencies in design, planning, and how outcomes were measured. Some tools required additional resources or had issues with technological accessibility. Only a limited number of studies performed cost-effectiveness analyses. Safety data were not reported in the included studies. No single tool is universally superior; each has advantages and limitations depending on how it is integrated into care pathways.
