亚拉巴马大学和伯明翰大学的生活空间评估（LSA）工具是一个有用的和创新的措施，在老年人口的流动性。本文的目的是评估的可靠性，结构和收敛效度的LSA在拉丁美洲老年population.Methods在一项横断面研究中，共有150名妇女和150名男子，年龄65-74岁，被招募的老年人社区中心在马尼萨莱斯，哥伦比亚和纳塔尔，巴西。LSA调查问卷总结了人们旅行的地点（从房间到镇外的5个级别），频率和所需的任何帮助。根据最大生存空间和独立性水平，获得了四个LSA变量。作为相关的LSA，教育，收入充足的看法，抑郁症，认知功能和功能的措施（客观和主观测量）进行了探讨。结果在马尼萨莱斯，LSA综合评分的可靠性显著（ICC = 0.70，95%CI 0.49-0.83）。平均水平的LSA得分较高的那些更好的功能表现和那些谁报告较少的流动性困难。低教育水平、收入不足、抑郁症状和认知功能低得分都与低LSA得分显著相关。在这两个城市的妇女更有可能被限制在他们的邻居，并有较低的LSA scores.Conclusion这项研究提供了证据LSA在两个拉丁美洲人群的有效性。我们的研究结果表明，LSA是一个很好的衡量流动性的指标，反映了身体功能与性别以及社会和物理环境的相互作用。
Background The Life-Space Assessment (LSA) instrument of the University of Alabama and Birmingham study is a useful and innovative measure of mobility in older populations. The purpose of this article was to assess the reliability, construct and convergent validity of the LSA in Latin American older populations.Methods In a cross-sectional study, a total of 150 women and 150 men, aged 65-74 years, were recruited from seniors' community centers in Manizales, Colombia and Natal, Brazil. The LSA questionnaire summarizes where people travel (5 levels from room to places outside of town), how often and any assistance needed. Four LSA variables were obtained according to the maximum life space achieved and the level of independence. As correlates of LSA, education, perception of income sufficiency, depression, cognitive function, and functional measures (objective and subjectively measured) were explored. The possible modifying effect of the city on correlates of LSA was examined.Results Reliability for the composite LSA score was substantial (ICC = 0.70; 95 % CI 0.49-0.83) in Manizales. Average levels of LSA scores were higher in those with better functional performance and those who reported less mobility difficulties. Low levels of education, insufficient income, depressive symptoms, and low scores of cognitive function were all significantly related to lower LSA scores. Women in both cities were more likely to be restricted to their neighborhood and had lower LSA scores.Conclusion This study provides evidence for the validity of LSA in two Latin American populations. Our results suggest that LSA is a good measure of mobility that reflects the interplay of physical functioning with gender and the social and physical environment.
