This article reports on a door-to-door survey used to create a population-based twin register in Sri Lanka. The goal of this survey was to identify twins older than 18 years. A similar methodology was also used to identify a nontwin sample in order to determinate the degree to which twins were representative of the wider population. Several questionnaires, including some on suicide ideation, were adapted & translated. (13 refs.)
