Standard Depression Screening Tools May Miss Key Symptoms in South Asian Patients, University of Surrey Review Finds
A University of Surrey-led review finds that physical pain, heart-related sensations, and repetitive negative thinking — common depression symptoms in South Asian communities — are absent from U.S. diagnostic screening criteria, potentially leading to widespread underdiagnosis in this population.
A new systematic review led by researchers at the University of Surrey has found that standard depression screening tools widely used in the United States may fail to capture several symptoms most commonly reported by South Asian patients. According to the review, physical pain, heart-related sensations — such as palpitations or chest tightness — and repetitive negative thinking are among the most frequently reported manifestations of depression within South Asian communities. Critically, none of these symptoms appear in the diagnostic criteria currently used to screen for depressive disorders in the U.S. The findings raise significant concerns about the validity and cultural sensitivity of widely deployed instruments such as the PHQ-9 (Patient Health Questionnaire-9), which forms the backbone of depression screening in primary care settings across the country. Researchers note that the underrepresentation of these somatic and cognitive symptom profiles in standard criteria could lead to systematic underdiagnosis of depression among South Asian patients — a population that already faces documented barriers to mental health care, including stigma and cultural differences in expressing psychological distress. The review did not constitute a randomized controlled trial (RCT) but rather a literature review, which carries inherent limitations including potential publication bias and variability in the quality of included studies. The size and diversity of the South Asian populations sampled across reviewed studies may also vary, and no conflicts of interest were noted in the available summary. Experts suggest that clinicians working with South Asian communities should supplement standard screening tools with culturally informed assessments that account for somatic presentations of depression. The review underscores a broader challenge in global mental health: diagnostic frameworks developed predominantly in Western contexts may not translate equitably across cultures.

VITALIS: This could mean a lot of South Asian folks dealing with depression through body aches or constant worry never get spotted or helped by standard check-ups, leaving them to struggle quietly. In the future we might see doctors and apps start listening to how different cultures actually feel sadness, so more everyday people finally get the right support.
