Diffusion of Innovation and Social Ecological Model Detailed Study Notes

Diffusion of Innovation Framework

  • Definition: The process by which new ideas spread throughout a population or social group.
  • Four Core Constructs:
    • The innovation itself
    • Communication channels
    • Time it takes to adopt
    • The social system in which groups live

Construct 1: The Innovation

  • Definition: Something new or novel, representing anything that differs from what has previously existed.
  • Factors Influencing Success or Failure (Adoption vs. Rejection):
    • Relative Advantage: The degree to which the innovation is superior or more advantageous than existing alternatives currently available.
    • Compatibility: How well the innovation aligns with existing social norms, values, and cultural beliefs.
    • Trialability / Suitability: The degree to which the innovation can be experimented with, tested, or tried on a limited basis prior to full commitment.
    • Complexity vs. Ease of Use: How simple or difficult the innovation is to understand and operate.
    • Observability: The degree to which the results and benefits of using the innovation are visible to others.
  • Adoption Rule: Innovations that are helpful, compatible with social norms, triable, easy to use, and yield observable results experience significantly higher rates of adoption.

Construct 2: Communication Channels

  • Definition: The specific format or medium people use to share information and spread awareness about an innovation.
  • Social Process: Diffusion is fundamentally a social process that occurs as individuals engage in sharing information about something new.
  • Mass Media Channels:
    • Types: Social media, newspapers, radio, and television.
    • Function: Reaches a large audience very quickly.
    • Impact: Makes the audience rapidly aware of a new product, idea, or innovation.
  • Word of Mouth:
    • Functions as an effective communication format depending on the specific nature and context of the conversation.

Construct 3: Time and Adoption

  • Definition: Represents how long it takes different segments or groups within a society to adopt an innovation, along with the specific stages involved in that adoption process.
  • Segments of the Adoption Curve:
    • Innovators:
    • The very first segment on the adoption curve.
    • Characterized as risk takers.
    • Represent a small percentage of the total population.
    • Possess a high tolerance and ability to cope with unpredictability.
    • Early Adopters:
    • Function as the opinion leaders of the community.
    • Highly respected individuals who possess intricate communication networks.
    • Connected to and knowledgeable about a diverse set of people.
    • Majority:
    • Divided into two distinct sub-segments along the adoption curve:
      • Early Majority: Positioned on the upward slope of the curve; strongly influenced by opinion leaders and mass media.
      • Late Majority: Positioned on the downward slope of the curve.
    • Late Majority:
    • Located on the downward side of the adoption curve.
    • Strongly influenced by their peers.
    • Wait to adopt until an innovation becomes an established social norm or absolute necessity.
    • Laggards:
    • Located at the end of the downward side of the adoption curve.
    • Characterized as conservative, traditional, and suspicious of innovation.
    • Highly risk-averse.
    • Wait a very long time before adopting an innovation.

The Innovation-Decision Process

  • Definition: The overall length of time and sequential steps required for different segments of a population to make a final decision regarding the adoption or rejection of an innovation.
  • Five Sequential Steps:
    1. Knowledge:
    • The essential first step in the process.
    • Individuals cannot make a decision about something new without knowing it exists.
    • Knowledge is gained directly through communication channels.
    1. Persuasion:
    • The stage where individuals begin developing an attitude (either positive or negative) toward the innovation.
    • Attitudes form through thinking about and mentally inserting the innovation into a present or future scenario, which leads toward the persuasion of acceptance or rejection.
    1. Decision:
    • Occurs when individuals choose to engage in activities that will lead directly to adopting or rejecting the innovation.
    1. Implementation:
    • Occurs when the decision is put into action and the individual begins actively utilizing or rejecting the innovation in practice.
    1. Confirmation:
    • The final step where individuals seek validation and confirmation from others to reinforce that their decision to adopt or reject was correct.

Construct 4: Social System, Social Capital, and Networks

  • Social System:
    • The fourth and final core construct of the Diffusion of Innovation framework.
    • Defined as a group of people (formal or informal) working together toward a common goal.
    • Systems embody shared norms, values, beliefs, and attitudes.
  • Social Capital:
    • Defined as the trusting and reciprocal interactions that individuals have with one another, which directly influence behavior.
  • Networks:
    • The structural connections that people maintain with others, allowing them to gain access to the collective resources of everyone within that network.
    • Networks range in scale from nuclear families to whole societies.
    • Mechanism: Once trust and reciprocity are established within a network, expectations and obligations increase. These connections and obligations drive attitudes and behaviors that are helpful to the entire group.

Types of Social Capital Relationships

  • Bonding Social Capital:
    • Relationships between individuals who share similar demographic characteristics, social identities, statuses, and resources.
    • Examples: Family members, friends, neighbors, and coworkers.
  • Bridging Social Capital:
    • Relationships formed between individuals who differ sociodemographically (such as differences in age, education, or ethnicity) but share common goals and interests.
    • Function: Enables individuals to engage in activities with mutually beneficial outcomes that are not possible through bonding relationships alone.
    • Examples: Church choir, volunteer fire department, and community theater group.
  • Linking Social Capital:
    • Relationships between individuals who interact across power or authority gradients, where one person holds dominance, control, or explicit influence over the other.
    • Examples: Teacher and student, clergy and parishioner, judge and criminal.

Social Ecological Model (SEM)

  • Definition: A theoretical framework that explains behavior as the result of a dynamic interplay among multiple factors operating across differing levels of influence.
  • Five Levels of Influence:
    1. Intrapersonal (or Individual):
    • Personal factors that directly affect individual behavior.
    • Key elements: Personal history, knowledge, attitudes, beliefs, personality traits, self-efficacy, perceptions, age, gender, and education level.
    1. Interpersonal (or Relationship):
    • The relationships maintained with others.
    • Functions: Provides social identity, establishes support systems, and defines personal roles within a social construct.
    1. Institutional (or Organizational):
    • Rules, regulations, and policies that shape environments.
    • Most commonly associated with workplace environments, but also includes religious organizations.
    1. Community:
    • Formal or informal norms, standards, and expectations held by individuals, groups, or organizations within a community.
    • Incorporates the Built Environment as community structures, including:
      • Parks
      • Safe playgrounds
      • Walking paths
    1. Societal (or Public Policy):
    • Broader influences on health and behavior stemming from laws, regulations, policies, social or cultural norms, and public attitudes.
    • Includes policies at the local, state, and federal levels that directly impact health, economics, and education.
