For the scientific credibility of study results, longitudinal cohort studies need to invest time, money and creative thought in establishing and maintaining the maximum number of study participants. Although success depends to a large extent on the resources available, much can be achieved by establishing a culture of integrity and enthusiasm among study staff that is conveyed to participants at all times. In this paper we outline various strategies that can be included in order to maximise the response rates.
