Mary Gottwald Principal Lecturer Student Experience February 2013 Oxford Brookes University Faculty of Health and Life Sciences

2 Predicting Health Behaviours – Behavioural change models

3 Learning Outcomes By the end of the module you will be better able to:
Understand the factors involved in predicting and explaining behaviour Understand the role of social cognition and stage models in predicting and explaining health behaviour Explore and understand in detail specific models Be able to critique models and apply to case scenarios.

4 Week 2 - overview 09.00 – 10.15am: Lecture 10.15 – 10.45am: Break 10.45 – 12 noon: Seminar

5 Predicting & explaining health behaviour
Complete the following: I feel healthy when…….. I feel healthy because….. To stay healthy I need……… I do not feel healthy when……. My health improves when……….

6 Predicting health behaviours
So…. How do we account for variability in behaviours? How do we account for variability in health?

7 Predicting and explaining health behaviour
Individual differences Locus of control (Rotter 1996) Internal External Multidimensional health locus of control (Wallston and deVellis 1978) External / chance Powerful others Modest predictor of behaviour

8 Health-promoting / risky health behaviours
What are risky healthy behaviours? What are health promoting behaviours? 8

9 Risky health behaviours
Global risks: Highest global risks to mortality = tobacco use, physical inactivity, being overweight and obesity (World Health Report 2012). Diet –high fat diet / being underweight Excessive alcohol Unsafe sex Not getting enough sleep Dangerous sports 9

10 Health-promoting behaviours
Alameda-seven Sleeping 7-8 hours a night Not smoking Consuming no more that 1-2 alcoholic drinks per day Getting regular exercise Not eating in between meals Eating breakfast Being no more than 10% overweight (Breslow 1983, cited in Morrison and Bennett 2006:61)

11 Individual differences and health
Younger, wealthier, better educated individuals with low stress levels and high social support are more likely to engage in health-enhancing behaviours (exercise, nutrition, non-smoking, low alcohol intake). If a person experiences high stress, fewer social, emotional and economic resources, they are more likely to be engaged in health compromising behaviours (smoking, high alcohol intake, sedentary lifestyle or poor nutrition).

12 Understanding cognition
Cognitive factors: Shape health behaviour Predict behaviour through self-regulation Social cognition models describe key cognitions and their interrelationships in the regulation of behaviour.

13 Social Cognition Cognitions:
Represent our thoughts, beliefs and knowledge towards a behaviour. Are intrinsic to us. Are modifiable determinants of behaviour. Give rise to social behaviour. Behaviours have an impact on morbidity and mortality.

14 Social Cognition Models
Help us to understand and predict health behaviours: Knowledge, perceived social norms, beliefs, attitudes and self-efficacy are linked to behavioural intentions and health related behaviour. Help us to explore the extent to which cognitions predict and explain behaviour. Continuum v stage models

15 Self-efficacy - Bandura
‘The belief that you can carry out a specific behaviour in a specific situation’ (Bandura 1997 cited in Upton and Thirlaway 2010:21) i.e. if you believe that you can do it then you will! ‘I can’t do it’ ‘I can’ So, self-efficacy beliefs directly determine behaviour (or action) 15

16 Enhancing self-efficacy
Observational learning / participatory learning. Verbal persuasions Perception of psychological and affective states. (Davis and Macdowell 2006)

17 Continuum v stage models
Health Belief Model Theory of Reasoned Action / Planned behaviour Health Action Model Prototype Willingness Model Dual-Process Models Individuals are likely to perform a (health related) behaviour based on their position on a continuum. 17

18 Continuum v stage models
Stage model Transtheoretical Stages of Change Model (TTM)  Individuals move through ‘stages’ before achieving a change in their (health related) behaviour 18

19 Behaviour change models
Models help us to explain and predict health behaviour. However, the decision we make about whether we decide / don’t decide to change our health related behaviour is based on cues and information we have in relation to our social, physical and cultural environment. Motivation also impacts on our decision making. All models have strengths and limitation. (Edberg 2007, Marks et al 2011, Gottwald and Goodman-Brown 2012)

20 Health Belief Model 1950s Hochbaum, Rosenstock, Becker
Focuses on understanding an individual’s perception of reality rather than how they respond to a situation. Considers a number of factors that may predict the likelihood of changing health related behaviours. Initial research linked to motivation.

21 Health Belief Model (Goodman-Brown and Gottwald 2008)
Perceived susceptibility Self efficacy Likelihood of taking action Perceived success Perceived severity Perceived benefits Cues to action 21

22 Theory of Reasoned Action
Ajzen and Fishbein 1980 Behaviour is dependent on two variables: Attitudes – beliefs about the consequences. Subjective norms – how much the individual wants to conform and be like ‘significant others’. Attitudes + norms = an intention to change.

23 Theory of Planned Behaviour

24 Theory of Reasoned Action
Beliefs about the consequences of taking action and judgement of those consequences Attitude Behavioural intention Behavioural change Beliefs whether Others in their networks would approve and motivation to comply with others Subjective Norm

25 Theory of Planned Behaviour
Ajzen added another variable: Behaviour is a consequence of perceived control Internal locus of control External locus of control There is some correlation between PBC and intention. Attitudes + PBC + intention = influence behaviour (e.g. uptake of exercise)

26 Theory of Planned Behaviour
Beliefs about the consequences of taking action and judgement of those consequences Attitude Beliefs whether 0thers in their networks would approve and motivation to comply with others Behavioural intention Behavioural change Subjective Norm Internal control factors External control Perceive behavioural control

27 STAGES OF CHANGE (TTM) (Prochaska and DiClemente 1984)
Pre-contemplation not thinking of change / not aware of a need to change Contemplation considering change – advice needed Commitment ready to change – practical support and achievable goals needed Action making the change – support and encouragement still needed Maintenance maintaining the change in their lifestyle – developing coping strategies Relapse support needed to return to contemplation 27

28 Preparation Long term change Action Contemplation Maintenance Relapse
(Adapted from Prochaska and DiClemente, 1984) Pre-contemplation 28

29 STAGES OF CHANGE (TTM) Exit Exit Exit Exit Action Maintenance
Commitment Relapse Exit Exit Contemplation (Gottwald, cited in Davis 2006) Pre-contemplation 29

30 STAGES OF CHANGE (TTM) Pre-contemplation: denial / low self-efficacy / barriers to change Contemplation: Seek information. Reduced barriers / increased benefits Preparation: Set goals, prioritise, concrete plans (join a gym) Action: Realistic goals essential / social support. Maintenance: Need to self monitor / need positive reinforcement. 30

31 Health Action Model (Gottwald and Goodman-Brown 2012:79)
Belief, motivation and normative systems Translating behavioural intention Action Knowledge and skills Personality factors: self- concept and self-sentiment Barriers, facilitating and environmental factors: social, physical, cultural and socio-economic

32 Summary Behavioural models enhance our understanding.
Can be used to predict all behaviours. These models focus on individual cognitions – need to remember socio-economic factors, culture, religion and so on. Models help to explain and understand complex situations and suggest approaches to take to ensure effective health promotion. 32

33 Exam question Describe and critically evaluate one Social Cognition Model and its application to predicting and explaining a specific health related behaviour. 33
