Some families will not be offered Incredible Years and will instead carry on as normal using services available to them locally. The reason for this is because we do not know whether or not this new version of the Incredible Years programme is any more beneficial for parents and babies than these existing services. If you are in the group that does not receive Incredible Years you will still play a very important role in the study and we will be able to compare the benefits of both types of support. We will still visit you four times to complete questionnaires and the observation. You will still receive the vouchers and the DVD as detailed above.
