目的.设计了一种新的测量低强度活动人群闲暇时间体力活动（LTPAI）和家庭和工作体力活动（PAHWI）的测量工具。长期疼痛的患者和专业理疗师参与了这两种仪器的开发。评价LTPAI和PAHWI的重测信度。通过将LTPAI与测量老年人身体活动、六分钟步行试验和有氧能力的仪器进行比较，评估LTPAI的结构效度。人口37例女性FM患者，平均年龄46岁（SD 8.4），平均症状持续时间11年（SD 5.9）。研究人群在休闲时间进行体育活动的平均时间为每周5.2小时（SD 4.0）。LTPAI总分（ICC 0.86，CI 0.79 - 0.93）和PAHWI总分（ICC 0.91，CI 0.82 - 9.96）的重测信度较好。LTPAI与6分钟步行试验（r（s）0.40，p = 0.02）和其他体力活动测试（r（s）0.39，p= 0.02）之间存在显著相关性，LTPAI与有氧能力无相关性。在开发过程中确保了仪器的表面有效性。LTPAI和PAHWI的重测信度令人满意。LTPAI与6分钟步行试验和专为老年人设计的仪器之间存在显著但低的关联，而LTPAI与有氧能力之间没有发现关联。
Purpose. 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.
