Comm Foundations - Signal Secrets

Communication is the process of imparting or exchanging information. Health Communication uses these strategies to inform and influence individual/community decisions enhancing health.

  • Elements of Communication:

    • Sender (Source)
    • Message (Content)
    • Channel (Medium)
    • Receiver (Audience)
    • Feedback (Response)
    • Noise (Interference)
  • Types of Communication:

    • Verbal (Spoken words)
    • Non-Verbal (Body language, gestures, tone 📌 Kinesics, Proxemics, Paralanguage)
    • Written (Text, graphics)
    • Formal (Official channels) & Informal (Grapevine)

The Communication Process Diagram

  • Key Communication Models:
    • Shannon-Weaver (1949): Linear model (Sender → Channel (Noise) → Receiver). Highlights technical transmission & noise.
    • Lasswell's Formula (1948): "Who says What, in Which channel, to Whom, with What effect?" Focuses on process & effect.
    • Schramm's Model (1954): Interactive/Cyclical. Emphasizes shared "field of experience" for effective communication.

⭐ Schramm's model highlights that communication is most effective when the sender's and receiver's fields of experience (e.g., culture, background) overlap significantly.

Behaviour Change Theories - Nudge Tactics

  • Health Belief Model (HBM): Individual beliefs predict health behaviours.
    • Perceived Susceptibility: One's perceived risk of a condition.
    • Perceived Severity: Perceived seriousness of the condition & its impact.
    • Perceived Benefits: Belief in efficacy of advised action.
    • Perceived Barriers: Perceived costs/obstacles to action.
    • Cues to Action: Triggers for behaviour (e.g., symptoms, media).
    • Self-Efficacy: Confidence in ability to perform action.
  • Transtheoretical Model (TTM) / Stages of Change: Behaviour change is a process. 📌 PCPAMT
    • Precontemplation: No intent to change (next 6 mo). Unaware/resists change.
    • Contemplation: Thinking of change (next 6 mo). Ambivalent.
    • Preparation: Plans to change (next 1 mo). Small steps.
    • Action: Actively changing behaviour (< 6 mo).
    • Maintenance: Sustaining change (> 6 mo). Preventing relapse.
    • Termination: Change is permanent. 100% self-efficacy, no relapse temptation.
  • Theory of Planned Behaviour (TPB): Posits that behavioural intention is the most important determinant of behaviour.
  • Diffusion of Innovations Theory: Spread of new ideas/practices.
    • Innovators (2.5%): Venturesome.
    • Early Adopters (13.5%): Opinion leaders, respected.
    • Early Majority (34%): Deliberate.
    • Late Majority (34%): Skeptical.
    • Laggards (16%): Traditional, resistant.

⭐ The Early Adopters group in Diffusion of Innovations Theory is crucial for influencing wider adoption, acting as role models.

Health Comm Hacks - Bridge the Gaps

  • Barriers to Communication:

    • Physical: Noise, distance, uncomfortable environment.
    • Psychological: Emotions (fear, bias), mistrust, inattention.
    • Semantic: Jargon, complex terms, language differences.
    • Cultural: Varying beliefs, customs, health literacy.
    • Socio-economic: Education level, resource access, financial constraints.
  • Strategies for Effective Health Communication:

    • Active Listening: Focus, understand, respond thoughtfully.
    • Empathy: Acknowledge and validate patient's feelings and perspectives.
    • Clarity: Use simple, direct language; avoid medical jargon.
    • Appropriate Channels: Choose suitable media (verbal, visual, written) for audience.
    • Feedback: Encourage questions; use "teach-back" to confirm understanding.
    • Non-Verbal Cues: Align body language, tone, eye contact with message.
    • Cultural Competence: Respect diversity; adapt communication to cultural context.

⭐ The "teach-back" method, asking patients to explain in their own words, is a key strategy to ensure message comprehension and improve health outcomes.
