Mental Health Screening in Primary Care
Summary
Mental health screening in primary care encompasses systematic approaches to identify psychological distress, mood disorders and other psychiatric conditions at the earliest point of contact. Primary care practitioners increasingly employ brief self-report instruments, structured interviews and digital tools to detect conditions such as depression, anxiety and work-related stress. Effective screening facilitates timely referral, stepped-care interventions and integration with broader public-health initiatives. Despite clear benefits, challenges remain: the risk of overdiagnosis, the need for validated cut-off thresholds, workflow integration and variable patient engagement. Globally, tailored screening protocols reflect differing healthcare systems, resource availability and cultural attitudes towards mental health. The use of ultrabrief questionnaires alongside electronic health-record prompts and patient-facing digital platforms seeks to optimise coverage and equity in underserved populations. Emerging evidence underscores that screening alone may not improve outcomes unless embedded within a coordinated care pathway offering feedback, follow-up and accessible psychosocial support.

Mental Health Screening in Primary Care publication trend
The graph below shows the total number of articles in mental health screening in primary care across all publications each year (not limited to Nature Index journals).
Technical terms
Primary care: The first point of contact healthcare service where generalist clinicians assess and manage a broad range of health issues.
Screening tool: A brief questionnaire or structured instrument used to identify individuals at risk of a mental health disorder.
Patient Health Questionnaire (PHQ-9 and PHQ-2): Self-report scales measuring depressive symptoms; the two-item version is an ultrabrief prescreener derived from the nine-item form.
Sensitivity and specificity: Performance metrics of a screening tool; sensitivity is the ability to correctly identify those with the condition, specificity the ability to correctly identify those without it.
Ultrabrief screening instrument: A screening tool consisting of only one or two items, designed for rapid assessment.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
