Study Notes

Communication & Meaning

Communication is about how people use messages to create meaning.
Meaning can be influenced by the context, culture, and channel of communication.
We know if a message was understood by the response of the receiver.

Transactional Model of Communication

Communication is a transaction, not just a reaction or interaction.
In communication, meaning is created through a process of sending and receiving messages.
This process involves encoding and decoding.

Encoding & Decoding

Encoding is when the sender puts their thoughts into words, symbols, or gestures.
Decoding is when the receiver applies meaning to the message sent by the sender.
Both encoding and decoding happen simultaneously.

Noise

Noise is any interruption or distraction that affects the communication process.
Examples of noise include:
- Receiver-side noise: Not hearing the message due to a noisy environment, being preoccupied with other thoughts.
- Sender-side noise: The sender not speaking the same language as the receiver.

Symbol Systems

Communication relies on shared symbol systems.
Symbols must be understood in the same way by both the sender and receiver.
Examples:
- Slang language and texting language can have different meanings to different people.
- Writing in all caps can be used for emphasis but can also be perceived as yelling or anger.

Communication & Technology

The field of communication benefits from advancements in psychology, neurology, artificial intelligence, and information technology.
Our perception, memory, and meaning-making abilities are all crucial aspects of communication.

Perceptual Process

Mood, internal attitudes, motives, experiences, and expectations influence sensory information intake.
Object characteristics like motion, sounds, size, novelty, and the context of the situation, such as time, place, and ambient conditions, influence perception.

Attribution Theory

Attribution theory explains how we determine the cause of events or behaviors.
The attribution process involves considering:
- Intentionality of the event or behavior.
- Internal or external factors influencing the event or behavior.
Weiner's classification considers:
- Distinctiveness: Does the behavior occur in other situations?
- Consensus: Do others behave similarly?
- Consistency: Does the behavior occur at other times?
Example: Observing a friend smoking at a party involves considering:
- Have you seen the friend smoke before (distinctiveness)?
- Are others in the group smoking (consensus)?
- Have you seen the friend smoke at other parties (consistency)?

Attribution

Externally attributed: An individual's behaviour is explained by external factors such as the environment or other people
Internally attributed: An individual's behaviour is explained by internal factors like personality, attitudes, and beliefs

Logical Rules/Heuristics

Selective perception: Our interpretations of what we see are influenced by personal interests, experiences, and background
Halo effect: A generalized impression about someone or something is formed based on a single characteristic (e.g., assuming someone is good at basketball because they are tall)
Contrast effect: Individuals are evaluated comparatively, being perceived as better or worse than the evaluator (e.g., believing someone has a better smile than yourself)
Projection: Attributing one's own characteristics to others (e.g., assuming someone is nice because you are nice)

Information Processing Theory

Representativeness: Recognition is based on similarity to a pre-existing prototype
Stereotyping: A form of representativeness based on group perception (e.g., assuming someone is good at math because they are Asian)
Availability: Decisions are made based on readily available information
Anchoring and adjustment: In quantitative situations, a starting point ("anchor") is used to estimate a final figure

Elaboration Likelihood Model (ELM)

Engagement with the topic leads to greater attention to new information
Other stimuli are needed to grab attention in the absence of a strong connection to the topic (e.g., a woman trying to get pregnant will be more likely to pay attention to pregnancy-related advertisements)

Successful Communication

Simplicity, brevity, and clarity are key to effective communication.
Emphasize cause and effect relationships for easier understanding.
Capture attention to ensure the message is received and remembered.
Utilize decision rules and heuristics to influence behavior.

Communication & Perception

Perception: How we process information, significantly impacts message reception and action.
Heuristics: Mental shortcuts we use, influence decision-making regarding messages.

Health Communication in Daily Life

Everyday Examples:
- Seeking health advice from family and friends.
- Observing health-related posters and advertisements in public spaces.
- Searching for health information online.
- Reading medication instructions.
- Noticing calorie information in restaurants.
- Engaging in social media discussions about health topics.
- Making health insurance or clinical trial decisions.
- Navigating healthcare facilities.

Strategic Health Communication

Utilizes communication strategies to engage individuals and communities to make health-conscious decisions.
Focuses on:
- Promoting critical thinking about personal health.
- Informing about healthy choices.
- Persuading individuals to adopt safe practices.

Definition of Health Communication

The study of how messages create meaning related to physical, mental, and social well-being.

Levels of Health Communication

Individual level: Effective health communication empowers individuals with knowledge about health risks, provides motivation and skills to make positive changes, connects individuals to support networks, and shapes positive attitudes.
Group level: Health communication often leverages social groups, such as religious congregations, gyms, schools, workplaces, or online communities, to deliver health programs.
Community level: This level focuses on influencing policymakers and public opinion to create healthier environments, increase access to healthy choices, and enhance healthcare service delivery.
Societal level: Through influencing individual and community values and attitudes, health communication ultimately shapes new societal norms and quality standards, contributing to health policy changes (e.g., laws on indoor smoking, child safety seat use).

Ecological Model

Interconnectedness: Our physical condition, behaviors, and surrounding environment influence the health and well-being of others.
Multiple Level Interventions: Interventions that address multiple levels of the ecological model, from individual to societal, are more effective than those focusing on a single level.

Systemic Determinants of Poor Health

Upstream Factors: Before addressing individual behavior change, it's vital to consider and address upstream factors that contribute to poor health, such as toxic waste, social disparities, limited healthcare resources, or poverty.
Communication limitations: Communication efforts alone cannot fully solve systemic health issues.

Challenges to Effective Health Communication

Information Processing: Health communication materials should be designed to be clear, engaging, actionable, and accessible to all audiences.
Access to Information: Challenges exist in reaching specific populations with health information, including the elderly, immigrants, individuals with low socioeconomic status, limited literacy, and disabilities.

Risk Perception

Cultural and belief systems can influence individual behavior, sometimes encouraging unhealthy or risky practices for group membership.
Information overload from various sources, including social media, can lead to the acceptance of anecdotes as trends and rumors as facts.
People often fail to consider probability and population size when assessing risk.
Risk perception is crucial in health communication, impacting both prevention efforts and risk presentation.

Risk Comparisons

Risk comparisons are used in healthcare to evaluate treatment options, explain chronic illness likelihood, and estimate environmental contaminant dangers.
Communicating risks effectively during emergencies is challenging and has led to the field of crisis and risk communication.

Key Concepts in Risk Communication

Causality: Determining if a factor (A) directly causes a disease (B).
Risk: Likelihood of developing disease (B) after exposure to a factor (A).
Hazard: Any source of potential harm (e.g., substance, energy, process, condition).
Exposure: Contact with a hazard, varying by method (e.g., inhalation, skin contact) and duration.
Toxicity: A substance's inherent capacity to cause adverse health effects.

Strength of Association

A relative risk value less than 2 does not definitively rule out a causal relationship between exposure and effect.

Dose-Response

A consistent increase in effect magnitude with increasing exposure levels strongly suggests a causal association.

Consistency of Response

A higher probability of a causal association exists if a similar effect is reported in multiple studies across diverse populations and conditions.

Temporal Association

Exposure must occur before the effect for a causal relationship to be considered. This is a fundamental requirement often overlooked.

Specificity of the Association

A strong association between a specific exposure and a rare health outcome (e.g., liver cancer) provides valuable evidence.
For common diseases with multiple causes, specificity is less helpful in establishing causality.

Biological Plausibility

A plausible explanation for how the exposure might lead to the effect through biological mechanisms strengthens the probability of a causal relationship.

Coherence

The proposed cause-effect interpretation should align with established knowledge about the natural history and biology of the disease.

Experimental Evidence

Findings in laboratory animals that replicate effects observed in humans support a causal association.

Analogy

Similar effects caused by structurally related chemicals can support a causal association, especially for certain compound classes.

Positive Self Opinion in Risk

A positive self-opinion can lead to an underestimation of risk.

Unreal Optimism or Optimism Bias

The more we know about a risk, the less likely we believe it will happen to us.
This is illustrated by smokers often believing they will not get lung cancer despite knowing the risks.
This can be seen as a form of cognitive dissonance, where we lessen the perceived risk to cope with the multitude of risks we face daily.

Health Communication

The health communication field has evolved numerous approaches to engage, inform, and persuade individuals about health issues at the personal, group, and community levels.
