This paper considers methodological approaches that can help better understand inequity in healthcare, focusing on five key domains: availability, patient-centeredness, access, effectiveness, and implementation. We present conceptual definitions of each of these domains, example research questions pertaining to inequity in each domain, and methodological approaches that can contribute to research about health inequities. We discuss the role of multilevel, participatory, and longitudinal research, particularly using representative, real-world data.

Probability surveys are challenged by increasing nonresponse rates, resulting in biased statistical inference. Auxiliary information about populations can be used to reduce bias in estimation. Often continuous auxiliary variables in administrative records are first discretized before releasing to the public to avoid confidentiality breaches.

Article Synopsis
  • Mass violence incidents (MVIs) cause significant psychological distress for survivors and communities, highlighting the importance of support services like mental health services, support groups, and religious support for recovery.
  • A study involving 5,991 adults from six communities affected by MVIs found that only about 20% were aware of available mental health services and even fewer reported using them.
  • Awareness and use of support services were more common among younger individuals with higher incomes and direct exposure to the MVI, indicating a need for better communication and outreach regarding these resources after such traumatic events.

In the past decade, depression has become more visible in the public conversation; depression has also become bound in national divides. We sought to assess (1) whether positive screen for depression is associated with political party affiliation and (2) whether use of mental health care varies by political affiliation. Positive screen for depression did not differ significantly for Republicans versus Democrats in Spring 2023.

Importance: Mass violence incidents (MVIs) are prevalent in the US and can have profound and long-lasting psychological consequences on direct survivors, but their outcomes among the broader communities where the MVI occurred are unknown.

Objective: To investigate the prevalence of and factors associated with past-year and current posttraumatic stress disorder (PTSD) among adults in communities that experienced an MVI.

Design, Setting, And Participants: This cross-sectional survey was completed between February and September 2020 with a household probability sample of adults from 6 communities that had experienced an MVI between 2015 and 2019: Dayton, Ohio; El Paso, Texas; Parkland, Florida; Pittsburgh, Pennsylvania; San Bernadino, California; and Virginia Beach, Virginia.

The integration of Artificial Intelligence (AI) into public health has the potential to transform the field, influencing healthcare at the population level. AI can aid in disease surveillance, diagnosis, and treatment decisions, impacting how healthcare professionals deliver care. However, it raises critical questions about inputs, values, and biases that must be addressed to ensure its effectiveness.

Commercial determinants of health frameworks aim to identify the features and actions of corporate entities that can influence health. This Viewpoint conceptualises the work of the news media as a set of commercial forces and provides a framework that can help researchers better understand how features and actions of the news media shape health and health equity. We discuss four key features of news media action that can shape health: agenda setting, framing, priming, and tactics of persuasion.

Psychiatric epidemiology has led to substantial progress in our understanding of the causes of mental health disorders. The increasing sophistication of etiologic psychiatric research has been accompanied by a greater focus on the biological and genetic causes of psychiatric disorders, to some extent diverging from field's early focus on the burden of poor mental health due to a breadth of social and economic conditions. We argue that the moment is ripe for advancing a mental health epidemiology that can reconnect the field to these earlier-and still central-concerns while retaining the strengths of psychiatric epidemiology.

Importance: Since 1999, over 1 million people have died of a drug overdose in the US. However, little is known about the bereaved, meaning their family, friends, and acquaintances, and their views on the importance of addiction as a policy priority.

Objectives: To quantify the scope of the drug overdose crisis in terms of personal overdose loss (ie, knowing someone who died of a drug overdose) and to assess the policy implications of this loss.

Introduction: Research has suggested that individual health may influence policy attitudes, yet the relationship between mental health and policy support is understudied. Clarifying this relationship may help inform policies that can improve the population mental health. To address this gap, this study measures national support for 5 social determinants of health policy priorities and their relation to mental health and political affiliation.

A substantial proportion of individuals with depression in the United States do not receive treatment. While access challenges for mental health care have been documented, few recent estimates of unmet mental health needs across insurance market segments exist. Using nationally representative survey data with participant-reported depression symptom severity and mental health care use collected in Spring 2023, we assessed access to mental health care among individuals with similar levels of depression symptom severity with commercial, Medicare, Medicaid, and no insurance.
