Abstract: The author reflects on his use of the American psychotherapist James Prochaska's stages of change theory. This model deals with individuals and how they move towards change, through stages of pre-contemplation to maintenance of changed behaviours. He presents examples of his use of the model with clients, when dealing with issues of smoking cessation and weight loss. He analyses his practice and interactions with clients, and affirms that stages of change model can be a useful tool to bring about change within clients. He suggests it gives clients the opportunity to contemplate change and gives nurses working in health promotion the opportunity to be part of the change process.
