lecture 2 - intro to beh change theories and models Flashcards
what are the most commonly reported personal barriers to exercise?
lack of time, lack of energy, lack of motivation, excessive cost, illness/injury, feeling uncomfortable, lack of skill and fear of injury
what are the most commonly reported environmental barriers to exercise?
lack of facilities, lack of a safe place, lack of childcare, lack of a partner, lack of support and lack of transport
what does a model do?
describes
what does a theory do?
explains
what is the purpose of beh change theories and models?
Evaluate the role of behaviour in the aetiology (symptoms) of illness, Evaluating the link between psychology and physiology, Predict unhealthy behaviours, prevent illness, and promote healthy behaviour, Understanding and evaluating the role of psychology in the experience and treatment of illness
what is prochaska and diclemente’s transtheoretical model?
(1) No single theory can account for the complexity of behaviour change
(2) Behaviour change is a process that unfolds over time through several stages
(3) Stages are open to change
(4) Specific processes and principles of change should be used at specific stages
what are the steps in the transtheoretical model in action?
precontemplation, contemplation, preparation, action and maintenance
how do we move through the stages in the transtheoretical model?
self-efficacy, decisional balance and processes of change
what are processes of change?
emotional awareness, societal support, pos thinking and behavioural rewards
evaluation of the transtheoretical model:
Considers the whole exercise behaviour change journey
Some measures are not valid or reliable
Descriptive, not explanatory
Stages allow for tailoring of interventions
what is protection motivation theory?
Suggests people are motivated to protect themselves from negative outcomes when they perceive threats
what are intrapersonal factors?
sources of information: personality variables, prior experience
what are environmental sources of learning?
verbal persuasion, observational learning
protection motivation theory evaluation:
Introduces explanatory cognitive mechanisms
Doesn’t consider the stage of behaviour change
Ethically questionable practical implications
what is schwarzers health action process approach?
Predicts and explains health behaviours, such as exercise
Explains why/how people move through stages and maintain/disengage with exercise (i.e., the mechanisms)
what is involved in the health action process approach?
Self-efficacy
Outcome expectancies
Risk perception
Perceived barriers and resources
what are the 5 principles of the health action process approach?
Behaviour change exists on a continuum (motivational to volitional)
Behaviour change exists in stages: pre-intenders, intenders, and actors
Planning mediates intention and behaviour
Planning is separated into action and coping
self-efficacy
evaluation of the health action process approach:
continuum - flexible, Explains mechanisms underpinning behaviour change
Acknowledges social factors
