IEC vs BCC

IEC - Information, Education, Communication

Definition: An approach that attempts to change or reinforce a set of behaviours in a target audience regarding a specific problem in a predefined period of time (WHO definition).
Focus: Providing information and raising awareness through educational materials.
Approach: One-way communication - expert to audience (top-down).
Assumption: That creating awareness will automatically lead to behavior change.
Limitation: "One size fits all" thinking; does not account for individual, social, or structural barriers.
Tools used: Posters, brochures, pamphlets, radio broadcasts, TV spots, flip charts.
Era: Popularized in the early 1990s as a step beyond basic health education.

BCC - Behavior Change Communication

Definition: A strategic communication process aimed at promoting and sustaining positive individual, community, and societal behavior change.
Focus: Not just informing, but actively motivating attitudinal and behavioral change.
Approach: More targeted and audience-specific; acknowledges that information alone is insufficient.
Assumption: Behavior change is complex and influenced by social norms, beliefs, and environment.
Strength: Addresses barriers to change, builds skills, and uses evidence-based theories (e.g., Health Belief Model, Social Cognitive Theory).
Tools used: Interpersonal communication, counseling, community mobilization, social media, peer education.

Key Differences at a Glance

Feature	IEC	BCC
Goal	Awareness and knowledge	Actual behavior change
Direction	One-way (top-down)	More participatory
Target	General population	Specific audience segments
Approach	Mass media, passive	Interactive, counseling-based
Theory base	Minimal	Strong (uses behavior change theories)
Feedback	Rare	Integral
Effectiveness	Limited to knowledge gain	Aims for sustained behavior change
Assumption	Knowledge = Action	Knowledge alone is not enough

Evolution: IEC → BCC → SBCC

The field has evolved further into SBCC (Social and Behavior Change Communication), which adds a social/structural layer:

IEC: Inform people
BCC: Change individual behavior
SBCC: Address social norms, community factors, and structural determinants together

Bottom line: IEC lays the foundation by creating awareness and knowledge. BCC builds on that by actively working to change behaviors using targeted, theory-driven, two-way communication strategies. In modern public health practice, BCC (and SBCC) is preferred over standalone IEC because knowledge alone rarely translates into sustained behavior change.

Operational Research in Community Medicine

(Short Note - Park's Textbook of Preventive & Social Medicine)

Definition

Operational research is defined as the application of scientific methods of investigation to the study of complex human organizations and services.

The main objective is:

"To develop new knowledge about institutions, programmes, use of facilities, the people working in these activities and the individuals and communities served by them" - in order to secure optimal utilization of resources in men, material and money in the service of the community.

Historical Background

The term "operational research" was coined during World War II in connection with the best use of a new invention - the radar.
Since the war, it spread rapidly in Britain and America and evolved to mean the study of whole systems of services in industry, administration, education, and health services.
A new emerging area is "Health Operational Research".

How It Differs from Other Research

Type	Description
Pure Research	e.g., mathematician studying atomic structure
Applied Research	e.g., engineer designing a new plant
Operational Research	Concerned with activities of a group of people with the purpose of inducing beneficial changes

Operational research is therefore a sociological science with an immense social content that distinguishes it from pure or applied research.

Phases of Operational Research

Formulation of the problem
Collection of relevant data (by suitable sample if necessary)
Analysis of data and formulation of hypothesis
Deriving solutions from the hypothesis or "model"
Choosing the optimal solution and forecasting results
Testing of solution - e.g., pilot projects
Implementing the solution in the whole system

Operational Research Team

Operational research is a team work job. The minimum composition for social medicine applications includes:

A Public Health Administrator
An Epidemiologist
A Statistician
A Social Scientist
Ancillary workers + a Director responsible for the whole project

Applications in Health Services

Practically everything in public health and social medicine can be a subject of operational research. Examples include:

Optimal size of area and population covered by a midwife or basic health unit
Ideal vehicle for local health workers
Architectural design of hospitals and health centres
Queuing problems in outpatient departments and hospital waiting lists
Integration problems in specialised services
Study of bed load and nursing services in teaching and non-teaching hospitals
Length of stay in hospitals; length of sickness absence
Effectiveness of programmes (e.g., malaria eradication, family planning)
Quality of medical care services
Investigation of epidemic outbreaks

"Whenever social medicine passes from the stage of observation and classification to that of discovering and recommending appropriate action, it is involved in operational research."

Key Points to Remember (Exam)

Coined during World War II (radar)
It is a sociological science (not pure/applied)
Goal = optimal use of resources (3 M's: Men, Material, Money)
7 phases (Formulation → Collection → Analysis → Hypothesis → Optimal solution → Pilot → Implementation)
Team includes: administrator + epidemiologist + statistician + social scientist
New area = Health Operational Research
