Adopting Health Belief Models Flashcards
(32 cards)
What are Health Behaviours?
- Activities undertaken to prevent or detect disease
- Activities undertaken to improve well-being
- Use of medical services or self-directed behaviour
- Restrict a behaviour or add a behaviour
- Episodic or long-term
why or why not? health behaviours
- Fear
- Benefits
- Costs
- Peer pressure / family pressure
- Social / cultural / religious norms
- Learned behaviour
- Confidence
The Importance of Health Behaviour Models
- understanding and predicting health behahiour decisions
- explain adherence and non-adherence
- generate research
- guide practitioners in promoting healthy behaviours
- design interventions to improve adherence
Continuum Theories
- one-size-fits-all’ approach
- First class of theories developed
- Single set of factors used to explain adherence
- Applies equally to all regardless of motivation to change
Continuum Theories (4 types)
- Health Belief Model
- Behavioral theory
- The Theory of Planned Behaviour
- Social Cognitive Theory
Health Belief Model
- (Becker & Rosenstock, 1984)
- Beliefs are an important contributor to health behaviour
- Beliefs about the disorder/disease and about health-enhancing behaviours
- Rational decisions are made on cost-benefit analysis
- -Susceptibility
- -Severity
- -Benefits
- -Barriers
Limitations of the Health Belief Model
- Relationship between variables is unclear
- Poor predictor of adherence for risk reduction behaviours linked to socially determined or unconscious motivations
- Important determinants omitted e.g. social influence and positive/negative effects of behaviour
- Needs to include sociopsychological factors
Behavioural Theory
- Based on principles of operant conditioning (B.F. Skinner, 1953)
- Focuses on the environment and teaching skills to manage adherence
- Positive reinforcement
- Negative reinforcement
- Punishment
- Antecedents (internal and external) and consequences influence behaviour
Behavioural Theory: Behaviour Change
- Patterns and habits are often resistant to change
- Need help establishing changes
- Cues – written reminders, phone calls, self-reminders
- Rewards – extrinsic (material, compliments); intrinsic (feel healthier, increased self-esteem)
- Contingency contracts – written, established at start of treatment
Behavioural Theory: strengths
- Predicts that adherence will be difficult
- Recognises that people need help establishing changes
Behavioural Theory: limitations
- Limited by its focus on external influences of behaviour
- Lacks an individualised approach
- Does not consider less conscious factors e.g. acceptance of diagnosis
- Does not consider the person’s perception of the rewards
The Theory of Planned Behaviour
- Information is used to decide how to behave
- Think about outcomes before taking action
- Choose to act / not to act
- Intention is an immediate determinant of behaviour
- Intention is shaped by three factors
1. Attitude Toward Behaviour
2. Subjective Norm
3. Perceived Behavioural Control
Theory of Planned Behaviour: limitations
- Assumes behaviours are under volitional control
- Assumes intention will actually lead to enacting the behaviour
- Does not consider the impact of past behaviour on current behaviour
- Components need to be directly relevant to -behaviour
- Structural barriers need to be taken into account
Social Cognitive Theory
- Social origins of behaviour + cognitive processes influence behaviour
- Self-Efficacy + Outcome Expectations predicts behaviour
- You must believe that your behaviour will bring about a valuable outcome AND that you have the ability to successfully carry out the behaviour
Social Cognitive Theory: Self-Efficacy Theory
A person’s belief in their ability to initiate difficult behaviours predicts the likelihood of achieving them
Social Cognitive Theory: Outcome Expectations
The belief that a specific behaviour will produce a valuable outcome
Self – Efficacy
- Feeling you have control over your behaviour
- Confident you can perform the necessary behaviour to achieve the desired outcome
Sources of self-efficacy
- Performance
- Vicarious experience
- Verbal persuasion
- Physiological arousal states
Social Cognitive Theory: Observational Learning
- Learning can occur in the absence of direct reinforcement through observing models
- Use of role models to shape cultural attitudes and behaviour
Social Cognitive Theory: strengths
- Good predictor of adherence
- Components incorporated into most other health behaviour models
Social Cognitive Theory: limitations
- omits other facotrs that also influence motivation e.g. stigma
- variables are difficult to operationalise
- The wide-range of focus may make it difficult to base interventions on this model
Stage Theories
- People pass through a series of discrete stages as they attempt to change their behaviour
- Describes the process of behaviour change
- Different stages → different variables are important
- Different stages → different interventions
- Interventions tailored to the specific stage
Stage Theories (3 types)
- The Transtheoretical Model
- The Precaution Adoption Process Model
The Health Action Process 3. Approach
The Transtheoretical Model
People progress through 5 stages in making behavioural changes 1. Precontemplation No intention of changing 2. Contemplation Aware of problem Thoughts about change 3. Preparation Thoughts and Action 4. Action Make overt changes in behaviour 5. Maintenance Sustain changes Resist temptation (Relapse Resume old behaviour) -Can relapse to a previous stage / first stage -Relapse is a learning experience
