title: Validity of a combined fibromyalgia (FM) questionnaires to asses physical activity levels in Spanish elderly women: an experimental approach.
abstract: Questionnaires designed to assess the level of physical activity among elderly Spanish speaking women usually have problems of reproducibility and are difficult to administer. This study aims to validate a Spanish combined version of two questionnaires originally designed to assess physical activity levels in fibromyalgia women. The leisure time physical activity instrument (LTPAI) and the physical activity at home and work instrument (PAHWI). Both questionnaires were translated to Spanish using translation/back translation methodology, and then were administered to 44 women aged 60-80 twice, with an interval of 2 weeks. During the first administration, participants answered the Yale physical activity questionnaires (YPAS) and performed the 6-min walking test (6MWT). Although the Spanish version of the LTPAI and the PAWHI showed poor test-retest reliability and poor construct validity, the sum of the two questionnaires showed much better associations. The results suggest that the Spanish combined version of LTPAI and PAHWI would seem to be useful tools for assessing the level of physical activity among elderly Spanish speaking women. Nevertheless, such considerations as the cultural adaptation of their content or the link between the intensity of physical activity as perceived and that actually done must be adjusted for greater efficiency.
