A new instrument measuring leisure time physical activity ( LTPAI) in populations predominately engaging in low intensity activities and a new instrument measuring the Physical Activity at Home and Work ( PAHWI) were designed. Methods. Patients with long-lasting pain and expert physiotherapists participated in the development of the two instruments. Test-retest reliability was evaluated for the LTPAI and the PAHWI. Construct validity was evaluated for the LTPAI by comparing it with an instrument measuring physical activities for older people, six-minute walk test and aerobic capacity. Population. 37 women with FM, with the mean age of 46 years ( SD 8.4) and mean symptom duration of 11 years ( SD 5.9) were recruited to the study. Results. The mean time that the study population spent in physical activities during leisure time was 5.2 hours ( SD 4.0) a week. Satisfactory test-retest reliability was found for the total score of LTPAI ( ICC 0.86, CI 0.79 - 0.93) and for the PAHWI ( ICC 0.91, CI 0.82 - 9.96). A significant association between the LTPAI and the six-minute walk test (r(s) 0.40, p = 0.02) and another physical activity instrument (r(s) 0.39, p= 0.02) was found. As expected, LTPAI did not have any association with aerobic capacity. Conclusions. Face validity of the instruments was ensured during the development process. Satisfactory test-retest reliability was found for the LTPAI and the PAHWI. Significant but low associations were found between the LTPAI and the six-minute walk test and an instrument designed for older people, respectively, while no association was found between the LTPAI and aerobic capacity.
