Method: Exploratory and confirmatory factor analyses were performed to assess the factor structure of frequency and limitation sub-scales of the LLDI. ANOVA and t test were used to determine the convergent and construct validity of the LLDI by exploring associations with physical performance tests, mobility limitations, depression, cognition, self-reported health, as well as with sex, education, and income. Results: Factor analysis resulted in one-factor solution and acceptable model fit. Participants with better physical function, less mobility limitations, better self-reported health, and intact cognition reported more frequent activities and fewer limitations, indicating good convergent and construct validity of our measure. Conclusion: LLDI is a good instrument to assess disability in low-income populations. Further research is needed to include culturally acceptable activities for the frequency sub-scale.<\/jats:p>","DOI":"10.1177\/0898264314523448","type":"journal-article","created":{"date-parts":[[2014,3,5]],"date-time":"2014-03-05T23:37:27Z","timestamp":1394062647000},"page":"495-515","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["Evaluation of the Late-Life Disability Instrument (LLDI) in Low-Income Older Populations"],"prefix":"10.1177","volume":"26","author":[{"given":"Afshin","family":"Vafaei","sequence":"first","affiliation":[{"name":"Queen\u2019s University, Kingston, Ontario, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fernando","family":"Gomez","sequence":"additional","affiliation":[{"name":"University of Caldas, Manizales, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria V.","family":"Zunzunegui","sequence":"additional","affiliation":[{"name":"Universit\u00e9 de Montr\u00e9al, Qu\u00e9bec, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jack","family":"Guralnik","sequence":"additional","affiliation":[{"name":"University of Maryland School of Medicine, Baltimore, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carmen L.","family":"Curcio","sequence":"additional","affiliation":[{"name":"University of Caldas, Manizales, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ricardo","family":"Guerra","sequence":"additional","affiliation":[{"name":"Universidade Federal do Rio Grande do Norte, Natal, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Beatriz E.","family":"Alvarado","sequence":"additional","affiliation":[{"name":"Queen\u2019s University, Kingston, Ontario, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2014,3,5]]},"reference":[{"key":"bibr1-0898264314523448","doi-asserted-by":"publisher","DOI":"10.1111\/j.1532-5415.2011.03392.x"},{"key":"bibr2-0898264314523448","doi-asserted-by":"crossref","unstructured":"Albala C., Vio F.
