Understanding how people make behavioural changes is key to helping modify their lifestyle in positive ways.
By gaining knowledge about why and how people make lasting behaviour changes, healthcare professionals can develop enhanced techniques to help modify their lifestyle in positive ways.

Making changes in behaviour is key to sustained weight loss, but changing behaviour is neither simple nor easy. Rather, human behaviour is a complex series of interrelated events. Understanding the ins and outs of behaviour change is an intense area of psychological research. Gaining knowledge about why and how people are able to make lasting behaviour changes can help people make positive lifestyle changes to lose weight and keep it off.
The Stages of Change (also called the transtheoretical model of behaviour change) was developed by James Prochaska and Carlo DiClemente in the mid-1980s. The model is based on a finding that people go through six stages of change on their way to making a sustained health-related behaviour change.
| Stages and Description of the Change Model1
|
| Precontemplation
|
Does not recognise that there is a problem
Denies there is a problem
Does not see the problem as serious
|
| Contemplation
|
Recognises the need for behaviour change
Is thinking about the pros and cons of changing the behaviour
|
| Preparation
|
Experimenting with small pieces of the behaviour change
|
| Action
|
Making definitive changes in aspects of the behaviour
|
| Maintenance
|
Maintaining new behaviour over time
|
| Relapse
|
Full or partial return to previous behaviours
Often accompanied by negative feelings
|

Among people not currently making an active behaviour change, it is estimated that 40% are in precontemplation, 40% are in contemplation and 20% are in preparation.
Matching the Next Step
At the heart of the model is the need to determine the person's stage of change and to match the 'next step' to get them to the next stage2. For example, a person in the precontemplation stage would be guided to learn about the health consequences of engaging in the desired behaviour change with a goal of getting her to think about it (i.e., contemplation) as opposed to providing specific 'do this now' instructions, an appropriate guidance for those in the action stage.
In addition, research has shown that people are likely to be at different stages of change for different behaviours. One study looked at the stages of change for four different health behaviours: exercise, protection from sun exposure, smoking and dietary fat consumption. Among the people who were surveyed, less that 20% were in the same stage of change for all four behaviours. The study's conclusion focused on the need to provide guidance based on people's stages of readiness for each behaviour being addressed.3
