The present commentary highlights and discusses two issues raised by Hobbis and Sutton (this issue): the identification of key beliefs, and the methods suggested by Cognitive Behaviour Therapy (CBT) for changing beliefs and behaviour. In relation to the first issue it is noted how the conception of key beliefs varies between the Theory of Planned Behaviour (TPB) and CBT. In relation to the second issue it is noted that CBT may well identify a number of useful techniques for changing beliefs, although a variety of other techniques may also be useful for changing beliefs.
