Time to Change is the largest national programme to counter stigma ever undertaken. It demonstrates that stigmatisation and its consequences are gradually becoming recognised as the most important obstacle to the development of mental health programmes. It also demonstrates that they can be prevented or reduced. The programme's evaluation answered many questions but others remain - concerning the indicators of success and ways of assessing them and relevance of the programme's achievements. The programme and its evaluation are important steps in the development of anti-stigma programmes worldwide.
