Theory of Planned Behavior (TPB)

Question 1

Theory of Planned Behavior (TPB)

• predecessor?
  
  • assumption?
• links?
• type of model?
• keystone

Answer 1

Extension of Theory of Reasoned Action (TRA)

• assumption: people are likely to do what they intend to

links beliefs & behavior (behavior guided by 3 types of beliefs)

A deliberative-processing model
→attitudes are formed after consideration of available info

• keystone = willful behavior
  
  • most behaviors are largely under volitional control ​

Question 2

Intentions (3)

motivational factors that impact behavior

indications of:

• how hard people are willing to try
• how much effort they are planning to exert

remain behavioral dispositions (attitude of mind) until appropriate time/opportunity

• attempt is made to translate into action

Question 3

Willful Behavior

Answer 3

Keystone to TPB

• behavior as a direct result of deliberate attempt by individual

Question 4

TRA vs. TPB

Answer 4

TPB added variable of percieved behavioral control

Question 5

According to TPB, health behaviors are?

Answer 5

a direct result of behavioral intention, which is made up of 3 components

Question 6

Behavioral Intention

Answer 6

→ motivational factors that influence behavior

• immediate antecedant of health behavior
• made up of (3) components

Question 7

Behavioral Intention

• (3) components

Answer 7

1) Attitudes
2) Subjective Norms
3) Percieved Behavioral Control

Question 8

1) Attitudes towards behavior

Answer 8

degree to which a person has favorable/unfavorable evaluation of behavior

involves consideration of potential outcomes

Question 9

2) Subjective Norms

Answer 9

belief of whether most people approve/disapprove of behavior
→ (percieved social pressure)

Question 10

3) Percieved Behavioral Control

Answer 10

perceived control over behavior (ease/difficulty of performing behavior)

• reflects obstacles & successes encountered in past experiences with behavior
• varies across situations & actions

Question 11

Principle of Compatibility

Answer 11

holds that each attitude & behavior has (4) elements:

a) Action

b) Target

c) Context

d) Time

correspondance between attitude & behavior is greatest when both are measured at same degree of specificity with respect to each element

Question 12

Principle of Compatibility

• holds that each attitude & behavior has (4) elements

Answer 12

ACTION (behavior)

performed on/towards TARGET

in particular CONTEXT

and at specific TIME (occasion)

Question 13

Importance of Principle of Compatibiltiy

Answer 13

In study of health behaviors, it is repeat performance of a single behavior across context & time that we wish to predict

Question 14

Description of TPB Model

• Main Goal?

Answer 14

Identifying determinants of behavioral intentions

Question 15

Description of TPB Model

• Main Assumption?

Answer 15

human beings usually behave in a sensible manner

Question 16

Description of TPB Model

• States that?

Answer 16

behavioral achievement depends on both:

motivation (INTENTION) & ability (behavioral control)

Question 17

Link between BELIEFS & BEHAVIOR

Answer 17

human behavior is guided by 3 kinds of considerations (beliefs), which influence intentions through attitudes, subjective norms & percieved behavioral control

Question 18

(3) Types of Beliefs

Answer 18

a) Behavioral
b) Normative
c) Control

Question 19

a) Behavioral Beliefs

Answer 19

beliefs about likely conseqeuences of behavior

• produce ATTITUDES (favorable/unfavorable) towards behavior

Question 20

b) Normative Beliefs

Answer 20

beliefs about normative expectations of others

• result in perceived social pressure (SUBJECTIVE NORM)

Question 21

c) Control Beliefs

Answer 21

beliefs about presence of factors that facilitate/impede performance of behavior

• result in PERCEIVED BEHAVIORAL CONTROL

Question 22

Key Constructs (6)

Answer 22

1) Attitudes
2) Behavioral Intention
3) Subjective Norms
4) Social Norms
5) Percieved Power
6) Perceived Behavioral Control

Question 23

Percieved Power

Answer 23

percieved presence of factors that facilitate/impede performance of behavior

• contributes to PBC over these factors

Question 24

What (5) factors combine to produce Behavioral Intention & ultimately behavior change?

Answer 24

Attitudes
Subjective Norms
Social Norms
Percieved Power
Percieved Behavioral Control

Question 25

Behavioral Intention

• represents?

Answer 25

one’s motivation (conscious plan), decision or self-instruction to perform target behavior

Question 26

Studies → Intentions & Actions (Behavior)

Answer 26

Findings that intentions are closely linked to volitional actions & can predict with high degree of accuracy

• however, this is not always the case

Question 27

Studies → Intentions & Actions (Behavior)

Intentions are closely linked to willful behavior & can predict them with high degree of accuracy

• However, this is not always the case → Explain

Answer 27

Longer time intervals increase likelihood that unforeseen events will change intentions

Feedback can significantly reduce accuracy with which intentions predict behavior

Question 28

Summary of TPB Research (5)

• (4) limitations

Answer 28

predicts broad range of health behaviors

Not good at:

• explaining spontaneous behavior changes
• predicting long-term behavior change

Communications designed to change attitudes can evoke defensive/irrational processes

tends to overlook emotional variables (threat, fear, mood,

Question 29

Bipolar Adjective Scale

Answer 29

Scale used to assess TPB major constructs

• attitudes, percieved norms, percieved behavioral control & intention
