A new cross-national analysis reported by News-Medical suggests health systems may be failing patients whose mental health challenges intersect with chronic illness, unmet needs and lower trust in care.
WASHINGTON — People who rate their own mental health as poor are more likely to report lower-quality medical care and less confidence in the health system, according to a new study that adds to growing evidence that mental health cannot be separated from the broader experience of receiving health care.
The findings, reported by News-Medical and published in PLOS Medicine, come from an analysis of 32,419 adults in 18 high-, middle- and low-income countries. Researchers used data from the People’s Voice Survey, collected in 2022 and 2023, to examine how adults who assessed their mental health as poor, fair, good, very good or excellent described their use of health services, confidence in health systems, quality of care and ability to manage their own health.
The results point to a consistent experience gap. Across countries, respondents who reported poor mental health were more likely to have chronic illness, worse overall health, lower patient activation, lower confidence in health systems and poorer ratings of care quality. The pattern was not confined to one region, income group or type of health system, suggesting that people with mental health difficulties may face barriers and frustrations that cut across national models of care.
The study was led by Margaret E. Kruk of Washington University in St. Louis and colleagues. Its central message is not that poor mental health causes poor care, or that poor care causes poor mental health. The research was cross-sectional, meaning it captured associations at one point in time rather than proving causality. But the consistency of the findings raises a policy question with immediate practical importance: whether health systems are adequately designed for patients whose mental health challenges are tied to physical illness, social stress and difficulty navigating care.
That question has become more urgent since the COVID-19 pandemic, which intensified anxiety, depression, grief and isolation in many communities. As more people seek help for mental health concerns, health systems are under pressure to respond not only through psychiatric services, but through primary care, emergency departments, chronic disease management, maternity care and other everyday points of contact. The study’s authors argue that patients with poor mental health are showing up across the system, not only in specialty mental health settings.
The survey asked respondents to assess their own mental health using a simple scale, a method often used in population health research because it is quick, inexpensive and capable of capturing how people perceive their own well-being. Self-rated mental health does not replace a clinical diagnosis. A person may report poor mental health without having a diagnosed psychiatric disorder, while another may live with a diagnosis but describe their current mental health positively. Still, self-assessment matters because it captures the patient’s lived experience, including distress, confidence, resilience and perceived ability to cope.
The research also measured patient activation, a term used to describe how confident and equipped people feel in managing their own health. Lower activation among people reporting poor mental health is especially important. A patient who feels overwhelmed, anxious, depressed or distrustful may find it harder to schedule appointments, follow treatment plans, ask questions, challenge confusing instructions or persist through administrative obstacles. In that sense, mental health can shape not only the need for care, but the capacity to obtain and use care effectively.
The study’s international scope gives the findings added weight. It included more than 1,000 respondents from each of 18 countries, allowing researchers to look beyond a single national system. The proportion of people with poor or fair mental health varied sharply by country, and access to mental health care also differed widely. News-Medical reported that among respondents with poor mental health, the share receiving mental health care in the previous year ranged from 0.9% in Lao PDR to 52.4% in the United Kingdom.
Those differences show that treatment access remains highly unequal. But the more striking finding may be that poorer experiences of care appeared broadly across settings. Even in countries where more people had contact with mental health services, those with poor mental health often reported weaker trust and worse care experiences. That suggests that expanding access, while essential, may not be enough if the care itself feels fragmented, dismissive, rushed or difficult to navigate.
The implications are significant for primary care. In many countries, primary care clinicians are the first or only point of contact for people experiencing depression, anxiety, insomnia, chronic pain, substance use concerns or stress-related symptoms. These patients may arrive with physical complaints rather than a stated mental health need. If clinicians and systems treat mental health as a separate silo, they may miss the way distress affects communication, adherence, follow-up and satisfaction with care.
The findings also matter for patients with chronic disease. News-Medical reported that people with poor mental health were nearly twice as likely to have a chronic illness. That overlap is well recognized in clinical practice. Depression and anxiety can complicate diabetes management, cardiovascular disease, respiratory conditions, cancer care and chronic pain. Physical illness can also worsen mental health, creating a cycle in which symptoms, appointments, medications and uncertainty reinforce one another.
For health systems, the study points toward integrated care as a practical response. Integrated care does not simply mean placing a mental health clinic inside a hospital. It means designing services so that emotional distress, social needs and physical illness are addressed together. That can include mental health screening in primary care, referral pathways that actually function, team-based care, longer consultations for complex patients, peer support, care navigation and follow-up after missed appointments.
The research also highlights the importance of trust. Confidence in the health system is not an abstract measure. It influences whether people seek care early, disclose symptoms, follow medical advice and return after a negative experience. Patients who already feel mentally unwell may be especially sensitive to interactions that seem rushed, stigmatizing or confusing. A brusque appointment, unclear bill, long wait or dismissive response can deepen the sense that the system is not safe or responsive.
Stigma remains a major factor. People with mental health concerns often report that physical symptoms are minimized or attributed too quickly to anxiety or depression. Others may avoid discussing emotional distress because they fear being judged, labeled or treated differently. These dynamics can reduce the quality of care even when clinicians do not intend harm. Training health professionals to recognize and counter stigma is therefore not only a matter of compassion, but of clinical quality.
The study’s descriptive design means policymakers should be cautious in interpreting the results. It cannot determine whether improving mental health would directly improve ratings of care, or whether improving care quality would improve mental health. It also relies on self-reported data, which can be influenced by expectations, cultural norms, recent experiences and personal circumstances. But self-reporting is precisely the point when the outcome is patient experience. If people feel the care they receive is poor, that perception itself affects trust and engagement.
The findings arrive at a time when many health systems are struggling with workforce shortages, long waiting times, rising demand and financial pressure. In such conditions, patients with complex needs may be most likely to fall through gaps. A person dealing with depression, chronic illness and low confidence in the system may need more support than standard appointment structures provide. Without that support, unmet needs can accumulate until they become more costly and harder to treat.
The authors suggest that tracking patient experience among people with poor mental health could help health systems improve performance over time. That approach would shift mental health from a separate service category to a lens through which the whole system is evaluated. It would ask not only whether mental health treatment is available, but whether people with mental distress receive respectful, coordinated and effective care wherever they enter the system.
For patients, the study validates a common but often underrecognized experience: feeling mentally unwell can make the health system harder to use, and difficult care experiences can compound distress. For clinicians, it is a reminder that asking about mental health is not separate from treating the body. For policymakers, it is evidence that quality improvement must include the people least likely to feel empowered within the system.
The broader lesson is clear. Mental health is not a side issue in medical care. It shapes how people seek help, how they interpret interactions, how they manage illness and how much confidence they place in institutions built to protect their health. If health systems want to improve quality, they must pay closer attention to the patients who report the least confidence, the most unmet need and the poorest mental well-being.
