Student summary
Why This Research Matters
Healthcare workers make up a large and fast-growing part of the United States workforce, and the COVID-19 pandemic put a spotlight on how much stress, trauma, and burnout they carry. This record describes a funded research project, supported by the National Institute on Drug Abuse, that sets out to study these pressures over time. It is important to understand from the start that this is a study plan, not a finished study. The material available here explains what the researchers intend to examine and why; it does not report results, statistics, sample sizes, or conclusions. As a nursing student, you should read it as a well-reasoned argument for why certain questions matter, not as a source of proven answers.
The project focuses on a group that is often overlooked: non-prescriber, non-executive healthcare workers. These are the people who keep a facility running but do not write prescriptions or make executive decisions, for example nursing assistants, dietary aides, and custodial staff. The researchers point out that most existing studies on substance use, mental health, and suicidality among healthcare workers have concentrated on physicians and other higher-wage roles. Lower-wage workers, who frequently have fewer supports, less control over their schedules and workload, and greater exposure to occupational hazards, remain understudied. The project aims to help close that gap.
A central idea in the proposal is moral injury. The researchers define this as the psychosocial and behavioral impact of failing to prevent, or bearing witness to, acts that transgress deeply held moral beliefs and expectations. The plan is to examine how moral injury relates to changes over time in substance use, substance use disorders, problematic mental health symptoms, and suicidality. This is a proposed line of inquiry; the record does not claim to have measured these relationships yet.
What makes the approach notable is its emphasis on factors beyond the individual. Much of the scientific literature explains risk and resilience in terms of personal traits or choices. This project deliberately widens the lens to include social factors (such as social support, the behaviors of peer networks, and perceived norms) and environmental factors (such as working conditions, traumatic exposures, and general life stress). It also considers organizational, community, and societal influences, and how these intersect with a person's socioeconomic position. In addition, the researchers plan to study how workplace policies, programs, and practices may either raise risk or build resilience.
The project lists three main aims. First, to examine how moral injury affects changes in substance use, substance use disorders, mental health symptoms, and suicidality. Second, to examine the influence of other individual factors (like occupational level, job satisfaction, sleep quality, and quality of life) alongside social and environmental factors on these outcomes over time. Third, to examine the specific impact of workplace policies, programs, and practices on risk and resilience. The researchers plan to recruit a diverse sample of healthcare workers through social media, intentionally including low-wage healthcare support occupations.
The stated reason this work matters is practical. If researchers can identify modifiable social and environmental risk factors, meaning things that can actually be changed, then prevention and intervention efforts can target them. The proposal argues that population-level interventions, such as building psychosocially safe and healthy workplaces, may be more efficient and effective than focusing only on individuals.
For a nursing student, the value here is twofold. First, it models how to read a research proposal critically: you can appraise the rationale, the framing, and the design without mistaking a plan for evidence. Second, it names workplace realities that nurses and nursing support staff live with, including stress, trauma exposure, and moral injury, and frames them as legitimate targets for organizational change rather than personal failings.
A caution is important here. Because no results are reported, you should not draw any conclusion about how common substance use or suicidality actually is among these workers, or about what interventions work. Doing so would mean inventing findings the source does not contain. If you or a colleague are struggling with substance use, trauma, or thoughts of suicide, reach out to a qualified professional or a crisis line; this research record is about studying the problem, not treating it.
Source abstract
Study Overview
Healthcare workers represent a large and growing segment of the US workforce, and the strain of the COVID- 19 pandemic on the healthcare system has brought to light the significant stress, trauma, and burnout that healthcare workers experience. These experiences may have lasting effects on healthcare workers’ substance use, mental health symptomatology, and suicidality, particularly among those in lower-wage occupations. These workers often have fewer supports and resources, less autonomy in the workplace (e.g., scheduling/hours worked, workload), and experience greater occupational hazards than their higher-earning counterparts yet remain highly understudied. Most of the published studies related to substance use, mental health symptomatology, and suicidality among healthcare workers have disproportionately focused on physicians and other high-wage healthcare occupations. The objective of the proposed research is to examine the social (e.g., social support, peer network behaviors, perceived norms) and environmental influences (e.g., working conditions, traumatic exposures, life stress) on the substance use, mental health symptomatology, and suicidality of non-prescriber/non-executive healthcare workers over time, with particular attention to the effects of moral injury (i.e., psychosocial and behavioral impacts of “failing to prevent or bearing witness to acts that transgress deeply held moral beliefs and expectations”) and workplace policies, programs, and practices. The rationale for the proposed research is that identification of factors beyond the individual level that confer risk or protection to healthcare workers’ substance use, mental health symptomatology, and suicidality can inform the development of more effective prevention and intervention efforts, particularly as it relates to the implementation of psychosocially safe and healthy workplace practices. Individual-level explanations for people’s risk and resilience to substance use, mental health symptomatology, and suicidality remain dominant in the scientific literature. However, we will also focus on interpersonal, organizational, community, and societal factors – and their intersections with socioeconomic positioning – that affect the health, well-being, and risk for substance use, substance-related harms, and substance use disorders among healthcare workers. This research proposes to 1) examine the effects of moral injury on changes in substance use, substance use disorders, problematic mental health symptomatology, and suicidality; 2) examine the impact of other individual (e.g., occupational level, job satisfaction, sleep quality/disturbance, quality of life), social (e.g., social support, peer network behaviors, perceived norms), and environmental factors (e.g., working conditions, traumatic exposures, life stress) on these outcomes over time; and 3) examine the unique impacts of workplace policies, programs, and practices on the risk and resilience of healthcare workers. We will pursue these aims using an innovative approach and unique focus. The proposed research will examine a diverse sample of healthcare workers recruited via social media, including low-wage healthcare support occupations (e.g., nursing assistants, dietary aides, custodians). The proposed research is significant because the examination of factors external to the individual will identify modifiable social and environmental risk factors that are more efficient and effective intervention targets, given the broad impacts of population-level interventions.
Evidence appraisal
Main Findings
- This is a funded research proposal supported by the National Institute on Drug Abuse; it describes objectives, aims, and rationale but reports no results, effect sizes, or sample sizes.
- It targets an understudied group, non-prescriber and non-executive healthcare workers, including low-wage support roles such as nursing assistants, dietary aides, and custodians, noting prior research has focused on physicians and high-wage roles.
- Moral injury is a central proposed construct: the project plans to examine its role in changes to substance use, substance use disorders, mental health symptomatology, and suicidality over time.
- The project adopts a social-ecological framing, deliberately looking beyond individual traits to social, environmental, organizational, community, and societal factors and their intersection with socioeconomic position.

Practice transfer
Clinical Relevance
- Nurses and nursing support staff experience stress, trauma exposure, and moral injury; these are legitimate occupational concerns rather than personal weaknesses, though this proposal does not yet quantify their prevalence.
- Lower-wage healthcare support workers may have fewer resources and less autonomy; nursing leaders can watch for such disparities while awaiting evidence on which supports actually help.
- Workplace conditions such as scheduling, workload, and autonomy are framed as potential intervention targets, so organizations may consider psychosocially safe practices, recognizing this proposal has not yet tested which ones work.
- Any screening or support for staff substance use and suicidality should be handled confidentially with referral to qualified help; this record describes study design, not a validated screening tool.
- Because results are pending, clinicians should not act on assumed rates or interventions drawn from this record and should instead follow existing evidence-based occupational-health guidance.
Faculty notes
Educational Relevance
This record is an excellent teaching tool precisely because it is a funded research proposal rather than a completed study. Use it to train students to distinguish a research plan from evidence: it states aims, rationale, and constructs but reports no results, sample sizes, or effect sizes. Ask students to identify what claims the proposal is (and is not) entitled to make. It pairs well with a lesson on the social-ecological model, moving discussion beyond individual blame toward interpersonal, organizational, community, and societal determinants of health. The construct of moral injury offers a rich entry point for discussing occupational mental health, burnout, and the specific vulnerabilities of low-wage healthcare support staff, a group students may join or supervise. Consider a class activity in which students critique the social-media recruitment strategy for representativeness and ethics, or design an outcome-measurement plan for one of the three aims. Emphasize YMYL caution: because there are no findings, students must not cite prevalence figures or interventions from this source. Close with a reflection on psychologically safe workplaces and confidential pathways to help for staff in crisis.
Critical appraisal
Limitations
- The record is a research proposal and funded-project description with no results; no findings, effect sizes, sample sizes, or conclusions are available to appraise.
- The planned sample is recruited via social media, which can limit representativeness and generalizability through self-selection and unequal digital access.
- Metadata is thin: there is no DOI, the identifier is a grant number (5R01DA059443-03), and the journal field names the funding institute rather than a peer-reviewed publication.

Frequently asked questions
Does this study prove that low-wage healthcare workers have high substance use?
No. It is a research plan and reports no results or prevalence rates. It only explains what the researchers intend to study and why.
What is moral injury, and why does it matter here?
It is the psychosocial and behavioral impact of failing to prevent or witnessing acts that violate one's deeply held moral beliefs. The project proposes to study how it relates to substance use, mental health, and suicidality.
Who is included in the study population?
Non-prescriber and non-executive healthcare workers, deliberately including low-wage support roles such as nursing assistants, dietary aides, and custodians.
What does a social-ecological approach mean in this context?
It means looking beyond individual traits to interpersonal, organizational, community, and societal influences, and how they intersect with socioeconomic position.
Is moral injury a formal diagnosis?
Not according to this record. It is described as a psychosocial and behavioral construct, not a formal psychiatric diagnosis.
Why recruit through social media, and what limitation does that create?
Social media allows a broad, diverse reach, but it can also reduce representativeness through self-selection and unequal access to the internet.
How could findings, once available, help nurses?
They could identify modifiable workplace and social factors, potentially guiding psychosocially safer workplaces. For now, no findings exist to apply.
Does the project offer treatment or crisis support?
No; it is research. Anyone in need should contact a qualified professional or crisis line.
How should a student cite this source?
As a funded research proposal describing aims and rationale, not as evidence of outcomes.
Is this relevant outside the United States?
It focuses on US healthcare workers, so its relevance to other countries and systems, including Canadian nursing, is uncertain.
