Comprehensive Overview of One Health, Arts and Health, Biomedical Model, and Diffusion of Innovation Theories

One Health — Theory Overview

One Health is an integrated framework that treats human, animal, and environmental health as interconnected and argues that many public health problems must be understood across all three domains.

One Health — Core Purpose

The core purpose of One Health is to address health problems that siloed systems miss, especially zoonotic disease, environmental exposure, and antimicrobial resistance.

One Health — Case Study Overview

The case study focuses on rising Valley Fever cases in a rural farming county in the Southwest.

One Health — Population and Context

The affected population includes farmworkers, their families, and ranch dogs, in a setting shaped by drought, disturbed soil, and nearby housing development.

One Health — Theory Use in the Article

The framework was used to examine the outbreak through linked human, animal, and environmental drivers instead of treating it only as a clinical issue.

One Health — Components Applied

The main components applied were the human-animal-environment triad, cross-sector collaboration, surveillance, and health equity.

One Health — How Components Explained the Issue

Human cases showed disease burden, canine cases acted as a sentinel signal, and drought plus soil disturbance explained the environmental exposure pathway.

One Health — Appropriateness of Application

The theory was applied appropriately because Valley Fever is shaped by environmental conditions, animal health signals, and human occupational exposure.

One Health — Strengths of Application

A major strength was that the framework integrated veterinary surveillance, clinical care, environmental change, and equity concerns in one explanation.

One Health — Limitations and Critique

A limitation is that One Health shows systems are connected but does not by itself solve power imbalances, funding shortages, or implementation barriers.

One Health — What the Theory Failed to Capture

It does not fully explain political, labor, and structural conditions that keep highly exposed groups like farmworkers underprotected.

One Health — Theory Expansion

The lecture suggests strengthening One Health with an explicit health equity lens that asks who benefits and who bears the burden.

One Health — Additional Perspectives to Strengthen It

The theory could be strengthened by adding labor policy, immigration and access issues, and stronger community voice as formal components.

One Health — Broader Application

One Health can also be applied to COVID-19, Ebola, avian influenza, Lyme disease, rabies, foodborne outbreaks, and antimicrobial resistance.

One Health — Why Useful in Other Contexts

It is useful because those problems also arise at the intersection of people, animals, and environments, so single-sector responses miss key causes and solutions.

Arts and Health — Theory Overview

Arts and Health is an umbrella framework for arts-based engagement that supports health through biological, psychological, and social pathways.

Arts and Health — Core Purpose

The core purpose is to address aspects of well-being that a narrow disease model misses, especially mental health, social connection, coping, and quality of life.

Arts and Health — Case Study Overview

A lecture example is community drumming for older adults to address loneliness and mood, or bedside music during chemotherapy to reduce anxiety.

Arts and Health — Population and Context

The population includes older adults in community settings or patients receiving treatment in clinical settings where stress, isolation, and emotional well-being matter.

Arts and Health — Theory Use in the Article

The framework was used to show how arts engagement can improve health through multiple pathways at the same time rather than through one purely medical mechanism.

Arts and Health — Components Applied

The main components were arts engagement, arts participation, cultural context, and the mental, social, and physical health pathways.

Arts and Health — How Components Explained the Issue

In the drumming example, group participation improves mood through the mental pathway and reduces loneliness through the social pathway.

Arts and Health — Appropriateness of Application

The theory was applied appropriately because the outcomes involved coping, stress, participation, and social connection, not just symptom reduction.

Arts and Health — Strengths of Application

A strength is that it uses a biopsychosocial view of health and allows culture, meaning, and participation style to shape the intervention.

Arts and Health — Limitations and Critique

A limitation is that arts interventions are highly diverse, so they are harder to standardize and compare across studies.

Arts and Health — What the Theory Failed to Capture

It may under-explain structural barriers such as funding, transportation, disability access, and unequal access to arts programs.

Arts and Health — Theory Expansion

The framework can be expanded by giving more attention to mode, form, culture, and how people actually participate in arts experiences.

Arts and Health — Additional Perspectives to Strengthen It

It would be stronger with explicit equity and implementation components such as cultural relevance, disability accommodation, and community co-design.

Arts and Health — Broader Application

Arts and Health can be applied to depression, social isolation, chronic disease self-management, rehabilitation, health literacy campaigns, and patient support in hospitals.

Arts and Health — Why Useful in Other Contexts

It is useful when health outcomes depend on engagement, belonging, emotional coping, or communication rather than only clinical treatment.

Biomedical Model — Theory Overview

The biomedical model treats illness primarily as biological dysfunction and defines health mainly as the absence of disease.

Biomedical Model — Core Purpose

The core purpose is to explain disease through biological causes such as pathogens, genetics, and physiological dysfunction and to support diagnosis and treatment.

Biomedical Model — Case Study Overview

A class example is chronic back pain or long-term diabetes control, where biology alone does not fully explain patient outcomes.

Biomedical Model — Population and Context

The population includes people with chronic illness whose outcomes are shaped not only by biology but also by stress, work conditions, sleep, coping, and adherence.

Biomedical Model — Theory Use in the Article

The biomedical model was used as the dominant frame by focusing on identifying disease, diagnosing it, and targeting biological intervention.

Biomedical Model — Components Applied

The main components applied were biological reductionism, mind-body dualism, objectivity over subjectivity, and physician as expert with patient as recipient.

Biomedical Model — How Components Explained the Issue

In chronic back pain, the model privileges scans and procedures while overlooking psychosocial and environmental influences on pain and function.

Biomedical Model — Appropriateness of Application

The model is appropriate when a condition has a strong biological driver and a clear biomedical treatment, such as acute infection.

Biomedical Model — Strengths of Application

A major strength is that it provides diagnostic clarity and targeted treatment when biological mechanisms are direct and measurable.

Biomedical Model — Limitations and Critique

A limitation is that it under-specifies behavioral, psychological, social, and environmental determinants of health.

Biomedical Model — What the Theory Failed to Capture

It does not explain well why patients with similar disease biology can have different outcomes because of stress, resources, support, or behavior.

Biomedical Model — Theory Expansion

The model can be expanded by incorporating broader views of health beyond disease absence.

Biomedical Model — Additional Perspectives to Strengthen It

Adding biopsychosocial and structural determinants would strengthen the model because sustainable health outcomes often depend on more than biological targets.

Biomedical Model — Broader Application

The biomedical model is useful in acute infection, trauma care, emergency medicine, genetic disease, and surgery.

Biomedical Model — Why Useful in Other Contexts

It is useful where disease mechanisms are clear, biological testing is central, and clinical treatment can directly change outcomes.

Diffusion of Innovation — Theory Overview

Diffusion of Innovation explains how new ideas, technologies, behaviors, or policies spread through a population over time.

Diffusion of Innovation — Core Purpose

The core purpose is to explain why some public health innovations are adopted quickly while others spread slowly or fail.

Diffusion of Innovation — Case Study Overview

The main lecture case study is smokefree policy adoption, with social distancing during COVID as another example.

Diffusion of Innovation — Population and Context

The population includes communities, organizations, and policymakers deciding whether to adopt a policy or intervention over time.

Diffusion of Innovation — Theory Use in the Article

The theory was used to analyze who adopted the innovation first, who influenced others, what barriers slowed adoption, and what helped the policy spread.

Diffusion of Innovation — Components Applied

The main components were innovation, diffusion, communication channels, time, social system, innovation attributes, adopter categories, and opinion leaders.

Diffusion of Innovation — How Components Explained the Issue

The theory examined whether the policy showed relative advantage, compatibility, observability, trialability, and manageable complexity, while tracking innovators and early adopters.

Diffusion of Innovation — Appropriateness of Application

The theory was applied appropriately because smokefree policy adoption clearly involves staged uptake across places and influence from trusted leaders.

Diffusion of Innovation — Strengths of Application

A strength is that it gives clear tools for analyzing spread, including innovation attributes, adopter categories, and the role of communication and opinion leaders.

Diffusion of Innovation — Limitations and Critique

A limitation is that the theory can focus too much on individuals, assume innovations are inherently good, and underplay resource constraints.

Diffusion of Innovation — What the Theory Failed to Capture

It may not fully explain political resistance, institutional distrust, inequity, or lack of resources that prevent adoption even when people see the innovation's value.

Diffusion of Innovation — Theory Expansion

Public health adaptations already expand the theory by emphasizing cost and simplicity alongside classic innovation attributes.

Diffusion of Innovation — Additional Perspectives to Strengthen It

The theory would be stronger if it included policy power, institutional trust, and structural inequities as core influences on adoption.

Diffusion of Innovation — Broader Application

It can also be applied to telemedicine, campus flu shot clinics, vaping cessation programs, mental health apps, naloxone training, and reusable water bottle campaigns.

Diffusion of Innovation — Why Useful in Other Contexts

It is useful because it helps public health workers identify early adopters, barriers to uptake, and strategies that make interventions easier to spread.

Health Communication — Theory Overview

Health communication is the study and use of communication strategies to inform and influence health decisions and promote broader social change in health.

Health Communication — Core Purpose

The core purpose is to explain how communication can increase knowledge, shape beliefs, prompt action, and support healthier behaviors and environments.

Health Communication — Case Study Overview

The main lecture case is Guinea worm disease, a parasitic infection spread by unsafe drinking water.

Health Communication — Population and Context

The population includes poor, remote communities in Africa with limited safe water, limited healthcare access, and a high need for community-based prevention.

Health Communication — Theory Use in the Article

The framework was used to show how public health programs must build awareness, tailor messages, recruit trusted leaders, and make information relevant to the audience.

Health Communication — Components Applied

The main components were audience analysis, relevance, trusted messengers, plain language, and theory foundations such as the Knowledge Gap Hypothesis and the Elaboration Likelihood Model.

Health Communication — How Components Explained the Issue

Knowledge Gap explained why some groups gain health information faster than others, while ELM explained why motivation, ability, and relevance affect how deeply messages are processed.

Health Communication — Appropriateness of Application

The theory was applied appropriately because Guinea worm prevention depends heavily on communication, behavior change, community awareness, and collective action.

Health Communication — Strengths of Application

A strength is that it used trusted formal and informal leaders, locally relevant examples, and audience-centered communication to support prevention.

Health Communication — Limitations and Critique

A limitation is that communication alone cannot compensate for inadequate healthcare access or sustain behavior change without broader structural support.

Health Communication — What the Theory Failed to Capture

It does not fully solve infrastructure problems such as unsafe water, poverty, and geographic isolation that make prevention difficult even when messaging is strong.

Health Communication — Theory Expansion

The lecture suggests expanding communication strategies by improving relevance, lowering literacy barriers, and anticipating emotional and motivational responses to risk information.

Health Communication — Additional Perspectives to Strengthen It

The framework would be stronger if paired with policy and infrastructure approaches, especially for diseases where behavior change depends on access to safe resources.

Health Communication — Broader Application

Health communication can also be applied to vaccination campaigns, sleep hygiene messaging, misinformation correction, GLP-1 communication, and chronic disease self-management.

Health Communication — Why Useful in Other Contexts

It is useful because it helps public health professionals decide whom to target, how to frame messages, how to increase relevance, and how to communicate in ways audiences can understand and use.
