What are the strengths and weaknesses of the Health Belief Model?

According to the social learning theory,

behavioural change is determined by environmental, personal and

behavioural elements. Each factor affects each of the others. For

example, an individual's thoughts affect their behaviour and an

individual's characteristics trigger certain responses from the

social environment. An individual's environment affects the

development of personal characteristics as well as the person's

behaviour, and an individual's behaviour may change their

environment as well as the way the individual think or feel. Social

learning theory focuses on the reciprocal interactions between

these factors, which are hypothesised to determine behavioural

change.
