1. Behavioral science is the study of human behavior through the lenses of psychology, sociology, and anthropology. It examines how individuals and groups act, think, and make decisions. 2. Understanding behavioral science is important for healthcare as it provides insights into patient behaviors, physician-patient interactions, and social and cultural factors that influence health and healthcare delivery. 3. Applying concepts from behavioral science such as perception, attitudes, values, and decision-making can help healthcare providers develop effective strategies and recommendations to address patient risk factors and health conditions.

2. Definition
Behavior is a response of an individual or group to an
action, environment, person, or stimulus.
1. Behavior is everything a person does.
2. Behaviors is
● that can be observed
• that can be heard/seen
• that can be measured

3. Behavior is the function of person’s characteristics and the
characteristics of surrounding environment

5. Eight parameters of behavior are:
B = Behavior
I= Identity of the individual who is behaving
W- Want
K= Knowledge (Cognition)
K-H= Know-How
P= Performance
A= Achievement
PC= Personal Characteristics
S= Significance.

6. Causes of Individual Behavior
• Inherited characteristics
• Learned characteristics

7. Learned characteristic

8. Perception is a way of regarding, understanding, or interpreting
something; a mental impression.

9. Perception
Perception is the understanding in one’s own perspective and
situation.

10. Personality
Personality is the combination of characteristics or qualities that
form an individual's distinctive character.
Type-A personality seeks challenges and Type-B personality seeks
status quo.

14. Attitude
Attitude is a settled way of thinking or feeling about someone or
something, typically one that is reflected in a person's behavior.

15. Values
-Values are the moral principles and beliefs or accepted standards
of a person or social group.
-Values are a person's or society’s beliefs about good behavior and
what things are important.

Our actions are determined by our behavior. Behavior is influenced by attitude and norms;
which again depend on our beliefs, learnt through observation, information from various
sources, including education and inferences drawn from any information interacting with
past experiences. Similarly ,behavior can be changed by providing appropriate education

18. Suppose you have a patient sitting in front of you. She is a 58-year-
old woman who works a lot and reports a high level of daily stress.
She is hypertensive, smoker for more than 30 years, is overweight
and has not been exercising regularly. She came to see you because
of low back pain and poor sleep. As a healthcare professional, you
want to help her.

19. One major goal is to address the risk factors for cardiovascular
disease, but you will also want to alleviate her current acute
conditions. At this stage, you can simply follow the guidelines and
give her advice on the benefits of exercise, weight loss, healthy
eating and decreased sodium intake, inform her about
atherosclerotic cardiovascular disease risks and prescribe
medication on an evidence basis.

20. But will these recommendations really work? Will she adhere to
your recommendations? And how can you know? What are the
applicable incentives and penalties for complying or not with these
guidelines?
Behavioral sciences provide a starting point for healthcare
professionals to address the questions raised above and improve
health care delivery.

21. Behavioral Science
Behavioral science is a branch of social science that derives its
concepts from observation of the behavior of living organisms.
Broadly defined, behavioral science is the study of human habits,
actions, and intentions.
Combining knowledge of sociology, psychology and anthropology
with strong observation, research, and communication skills, a
behavioral scientist works with communities and individuals
examining behavior and decision-making.

22. Behavioral science has three domains:
1. Psychology
2. Sociology
3. Anthropology

23. Psychology
-Psychology is the scientific study of the human mind
and its functions.
-Psychology is the scientific study of the mind and
behavior.
-Psychology is focused to individual person.

24. Sociology
Sociology is the study of the development, structure,
and functioning of human society. It is focused to a
group of people belonging to a society.
Sociology is the scientific study of society, including
patterns of social relationships, social interaction, and
culture.

25. Anthropology
Anthropology is the study of what makes us human.
Anthropology is the study of people throughout the world, their
evolutionary history, how they behave, adapt to different
environments, communicate and socialize with one another.
The study of anthropology is concerned both with the biological
features that make us human (such as physiology, genetic
makeup, nutritional history and evolution) and with social
aspects (such as language, culture, politics, family and religion).

26. Components of Behavioral Science
• Is a discipline
• Emphasizes human mental process
• Gives a ‘I’ feeling
• Individual demands empirical evidence
Psychology
• Is a discipline
• Emphasizes human society
• Gives a ‘we’ feeling
• Society demands empirical evidence that
links sociological ideas to live experience
Sociology
• Is a discipline
• Emphasizes human society, & association
in the past
• Empirical evidence that links with
documents, tools, fossil…
Anthropology

27. Topic domains for the behaviour science in
medical teaching:
1. Mind body interaction
2. Patient behavior
3. Physician role and behavior
4. Physician patient interaction
5. Social and cultural issues in health care
6. Health policy and economics

28. Relevance and importance of Behavioral Science to
Health & Medicine
Relevance is demonstrated in the:
-Aetiology of illness,
-Presentation of illnesses,
-Delivery of health care,
-Aspects of social and psychological treatment.

29. -Behavioral and social factors are important in planning
for health care with assessment and treatment of both
physical and psychiatric disorder.
-Cultural factors play a role in the behavior of the patient
and treatment.
-Psychological tests help in the psychiatric diagnosis.

30. -Systematic study of psycho-social phenomena (including problems)
in health and disease
-Investigating and understanding psycho-social crises related to
health and disease (e.g., disease outbreak)
-Explaining social responses to poverty, exclusion, marginalization,
prejudice and discrimination which influences healthcare services.
-Address the issues of healthcare provider - patient relationship

31. Categories of Behavioral Sciences:
Decision Sciences: Decision sciences deals with the decision
processes .
It concentrate mainly on Psychology.
Communication Sciences: Communication Sciences deals with
communication strategies used by human. Communication
implies human interaction and relationship.
It concentrate mainly on Sociology and Anthropology.

Scope

33. •Health behavior is a behavior that affects health:
–Health impairing habits, which is called "behavioral pathogens"
(for example smoking, eating a high fat diet)
–Health protective behaviors, which is defined as "behavioral
immunogens" (e.g. attending a health check).
-Illness behavior is a behavior aimed at seeking a remedy (e.g. going
to the doctor).
-Sick role behavior is an activity aimed at getting well (e.g. taking
prescribed medication or resting). In other words, sick role is
behavior and obligations expected from a sick person.
Health related Behaviors

34. -Illness behavior is described as the state when the
individual feels ill and behaves in a particular way
-Illness is a psychological concept:
– It has different meanings for different people
– It’s based upon an individual’s personal evaluation of
his/her bodily state and ability to function
Illness Behavior

36. Factors that Influence Illness Behavior

37. Suchman’s 5 stages of Illness Behavior

38. Stage 1: Symptom Experience
At this stage the person comes to believe something is wrong. Either
someone significant mentions that the person looks unwell, or the
person experiences some symptoms such pain, rash, cough, fever or
bleeding. It has 3 aspects:
1. The physical experience of symptoms.
2. The cognitive aspect (the interpretation of the symptoms in terms
that have some meaning to the person)
3. The emotional response (e.g. fear or anxiety)
During this stage, the unwell person usually consults others about
their symptoms or feelings. At this stage the sick person may try
home remedies. If self management is ineffective, the individual
enters the next stage.

39. Stage 2: Assumption of Sick Role
The individual now accepts the ‘sick role’ and seeks confirmation
from the family and friends. During this stage people may be
excused from normal duties and role expectations. Emotional
responses such as withdrawal, anxiety, fear and depression may
prevail. When symptoms of illness persist or increase, the person
is motivated to seek professional help.

40. Stage 3: Medical care contact
Sick people seek the advice of a health care professional either on
their own initiative or at the urging of significant others. When
people seek professional advice they are really asking for 3 types
of information:
1.Validation of real illness.
2.Explanation of the symptoms in understandable terms.
3.Reassurance that they will be alright or prediction of what the
outcome will be.
The health professional may determine that the client does not
have an illness or that an illness is present and may even be life
threatening. The client may accept or deny the diagnosis. If the
diagnosis is accepted, the client usually follows the prescribed
treatment plan. If the diagnosis is not accepted, the client may
seek the advice of other health care professionals or quasi-
practitioners who will provide a diagnosis that fits the client’s
perceptions.

41. Stage 4: Dependent-Patient Role
After accepting the illness and seeking treatment, the client
becomes dependent on the professional for help. People vary
greatly in the degree of ease with which they can give up their
independence, particularly in relation to life and death. Role
obligations-such as those of wage earners, father, mother, and
student-complicate the decision to give up independence.

42. Stage 5: Recovery or Rehabilitation
During this stage the client is expected to relinquish the
dependent role and resume former roles and responsibilities.
People who have long-term illness and must adjust their lifestyles
may find recovery more difficult. For clients with permanent
disability, the final stage may require therapy to learn how to make
major adjustments in functioning

43. Disease versus ill/illness behavior:
 Disease is physical malfunctioning of the body.
 Illness is subjective perception of whether one is
sick or not. It is possible to have a disease and not
feel ill, e.g., undetected diabetes. Also possible
to feel ill without any detectable disease, e.g.,
hypochondriasis.

44. Sick Role
• The sick role – any activity undertaken for the
purpose of getting well by those who consider
themselves ill.
• This is a social role.
• A patient who enters the sick role has both rights and
obligations.
• There are positives and negatives to the sick role.

45. Sick Role Behavior
There are four aspects of sick role behavior:
•The sick person is not at fault for being sick.
•The sick person is excused from usual (everyday)
responsibilities.
•The sick person must get well as soon as possible.
•The sick person must seek professional help.

46. Sick Role- Rights and Obligations

47. Behavior causing ill-health

48. Behavior related to Chronic Illness

49. Health-Related Behaviors for Chronic Disease
Prevention
Five key health-related behaviors for chronic disease prevention
are:
-Never smoking,
-Getting regular physical activity,
-Consuming no alcohol or only moderate amounts,
-Maintaining a normal body weight, and
-Obtaining daily sufficient sleep.

50. How to change a behavior

51. The Health Belief Model (HBM) is a psychological health behavior
change model developed to explain and predict health-related
behaviors, particularly in regard to the uptake of health services.
The health belief model suggests that people's beliefs about
health problems, perceived benefits of action and barriers to
action, and self-efficacy explain engagement (or lack of
engagement) in health-promoting behavior.
A stimulus, or cue (Peer pressure) to action, must also be present
in order to trigger the health-promoting behavior.
Health Belief Model (HBM)

53. Components of HBM
-Perceived susceptibility: This refers to a person's subjective
perception of the risk of acquiring an illness or disease.
-Perceived severity: This refers to a person's feelings on the
seriousness of contracting an illness or disease.
-Perceived benefits: The course of action a person takes in
preventing (or curing) illness or disease relies on consideration and
evaluation of both perceived susceptibility and perceived benefit,
such that the person would accept the recommended health action
if it was perceived as beneficial.

54. -Perceived barriers: This refers to a person's feelings on the
obstacles to performing a recommended health action. The person
weighs the effectiveness of the actions against the perceptions that
it may be expensive, dangerous (e.g., side effects), unpleasant (e.g.,
painful), time-consuming, or inconvenient.
-Cue to action: This is the stimulus needed to trigger the decision-
making process to accept a recommended health action. These cues
can be internal (e.g., chest pains, wheezing, etc.) or external (e.g.,
advice from others, illness of family member, newspaper article,
etc.).
-Self-efficacy: This refers to the level of a person's confidence in his
or her ability to successfully perform a behavior.

56. Yellow marked boxes are the target for educational intervention, to
ensure healthy practices.

58. Conclusion
• Mere focus on medicine and clinical domain of
healthcare are not sufficient to ensure health.
• Combination of knowledge of medicine and
skill in behavioral science are complimentary
for effective healthcare services.
• Focus on behavioral changes for compliance
to treatment, healthy practices and healthy
life-style are the challenges against prevailing
Chronic Diseases.

‘Slim TV’ with remote control has gifted a ‘fat owner’. Thus technology also changes
behavior.
