In order to ensure that leprosy patients are detected and treated adequately, it is essential that they are satisfied with the services provided. Their satisfaction can be analysed by assessing the quality of the services from a client perspective. This will give crucial information for the identification of strengths and weaknesses of leprosy services, e.g. in areas such as health seeking behaviour and regularity of treatment. It necessitates, however, that special attention is given to clients' opinions and ideas, both of which are rarely included in reviews and evaluations of leprosy programmes. Hence, an initiative was taken to formulate guidelines for the conducting of a study on client satisfaction. These guidelines were pre-tested in two countries, Nepal and Brazil. The development and contents of these guidelines are highlighted and discussed in this paper.
