“…At fi rst glance, nothing differentiates the execution of a psychometric study from any classic epidemiological study, since both require the same rigor in their processes. 49,50 In particular, it is of great interest to identify the domain of the population picked up in the study, thereby catching a glimpse of the extent to which the fi ndings may apply to the population among which the instrument will actually be used.…”

The objective of the article was to offer an operational framework to assess cross cultural adaptation processes of instruments developed in other linguistic, social and cultural contexts. It covers the need for using robust measurement tools; the importance of 'universal' instruments that permit cross cultural fi ne-tuning; and stresses the need for adapting existent instruments rather than developing new ones. Existing controversies and proposals for different procedures in current literature are reviewed and a model for adapting instruments is presented. This synthesis covers the operational steps involved in evaluating concepts, semantic and operational items, and presents psychometric analysis guidelines that underlay an evaluation of measurement equivalence. Finally, the need for adequately controlling the quality of information presented in epidemiological studies, including a meticulous cross-cultural adaptation of research agendas, is reinforced.

“…This is because it should be measured according to the dynamic at the time of the interview and is an important stage in the psychometric evaluation of instruments used in epidemiology. 15 This article reports the measuring of the test-retest reliability of the items on the scale of social capital resource providers in participants in the ELSA-Brasil.…”

OBJECTIVE:To estimate the test-retest reliability of items of the Resource Generator scale for assessing social capital in the Brazilian Longitudinal Study for Adult Health (ELSA-Brasil). METHODS:The social capital was applied in a subsample of 281 participants from six ELSA investigation centers, on two occasions with an interval of seven to 14 days. The instrument consists of 31 items that represent concrete situations to evaluate the access to different types of resources. In addition, it evaluates the strength of ties (family, friends or acquaintances) for the available resources. Statistical analyses were performed through use of the kappa statistic (k) and prevalence-adjusted kappa (ka). RESULTS: A high frequency was found for social resources (above 50%).Regarding the presence or absence of resources, prevalence-adjusted reliability (ka) varied from 0.54 to 0.97. With regard to the source for the resource, the reliability estimates ranged from ka= 0.45 ("someone who has good contacts with the media") to ka = 0.86 ("someone who completed secondary education"). CONCLUSIONS:The scale presented adequate levels of reliability, which varied according to the type of resource.
