“…Seven items measuring self-report of upper extremity function were selected from the Late-Life Function and Disability Instrument [30,31]. These seven items assess how much difficulty that the participant had while: 1) unscrewing the lid off a previously unopened jar without using any devices; 2) putting on and taking off long pants, including managing fasteners; 3) using common utensils for preparing meals, such as can opener, potato peeler, or sharp knife; 4) holding a glass full of water in one hand; 5) reaching behind his/her back as if to put a belt through a belt loop; 6) ripping open a package of snack food, such as cellophane wrapping on crackers, using only his/her hands; and 7) pouring from a large pitcher.…”

“…Although the LLFDI outcome measure has been widely used with the cardiac population (e.g., cardiac rehab post-bypass surgery, coronary heart disease, congestive heart failure) [26] [30] [32], to date, this is the only known research study to have explored the predictive validity of the LLFDI in terms of mortality and morbidity risk in elective cardiac surgery patients [30].…”

“…The comprehensive assessment of frailty (CAF) tool by Sundermann et al, however, is laborious to conduct for clinicians, and as yet, has not shown to be superior to cardiac risk score assessments [11]. There has been limited preoperative functional data collected to date since the STS announcement and no standardized approach taken with this recommendation to evaluate its impact on mortality and morbidity risk [8] [29] [30]. More comprehensive and perhaps more unique than any of the above tests mentioned, the LLFDI also indicates aspects on recreational participation and community socialization which significantly impacts one's quality of life and makes this an appropriate tool to use with the cardiac surgical population.…”

Background: Cardiac surgery, even when planned, has the potential for adverse outcomes, such that several factors are taken into consideration to help surgeons and their patients discuss the potential risks weighed against the expected recovery. Preoperative functional status and its influence on cardiac surgery, if any, have not been adequately evaluated to date. This study aimed to examine the relationship between preoperative functional status and postoperative mortality and morbidity in elective open heart patients. Methods: Preoperative baseline data (n = 43 subjects) were obtained to calculate Society of Thoracic Surgeons (STS) mortality and morbidity risk scores and preoperative functional status was measured using the Late-Life Function and Disability Instrument (LLFDI). Follow-up data were abstracted at one year postoperative to calculate actual mortality and morbidity events. Ordinary least squares and negative binomial regression analyses were conducted to assess the relationship between the LLFDI preoperative score to the STS mortality and morbidity risk scores. Results: Mortality risk was significant, F (1, 39) = 4.75, p = 0.035, with an adjusted R2 = 0.086, and Function Total (measured by LLFDI) yielded a significant negative association with mortality risk, β = −0.329. Morbidity was found to be significant, F (1, 40) = 4.89, p = 0.033, with an adjusted R2 = 0.087 and Function Total yielded a significant negative association with morbidity risk, β = −0.328, as well. Estimation of the counts for postoperative complications as estimated by Function Total failed to reach significance (Wald χ2 = 0.34, p = 0.56), which provided a pseudo R2 = 0.009.

“…13,14 Additionally, responsiveness to meaningful change, moderate to strong construct and predictive validity have been demonstrated. 16 However, the LLFDI suffers from two major limitations. Similar to comparable patient reported outcome measures for PF and disability, it takes a long time to complete the LLFDI (>20 minutes on average for the combined function and disability scales) and all questions are administered to all patients regardless of their applicability, making it difficult to use in clinical care.…”

Translation, Validation, and Reliability of the Dutch Late-Life Function and Disability Instrument Computer Adaptive Test

Background Adequate and user-friendly instruments for assessing physical function and disability in older adults are vital for estimating and predicting health care needs in clinical practice. The Late-Life Function and Disability Instrument Computer Adaptive Test (LLFDI-CAT) is a promising instrument for assessing physical function and disability in gerontology research and clinical practice. Objective The aims of this study were: (1) to translate the LLFDI-CAT to the Dutch language and (2) to investigate its validity and reliability in a sample of older adults who spoke Dutch and dwelled in the community. Design For the assessment of validity of the LLFDI-CAT, a cross-sectional design was used. To assess reliability, measurement of the LLFDI-CAT was repeated in the same sample. Methods The item bank of the LLFDI-CAT was translated with a forward-backward procedure. A sample of 54 older adults completed the LLFDI-CAT, World Health Organization Disability Assessment Schedule 2.0, RAND 36-Item Short-Form Health Survey physical functioning scale (10 items), and 10-Meter Walk Test. The LLFDI-CAT was repeated in 2 to 8 days (mean=4.5 days). Pearson's r and the intraclass correlation coefficient (ICC) (2,1) were calculated to assess validity, group-level reliability, and participant-level reliability. Results A correlation of .74 for the LLFDI-CAT function scale and the RAND 36-Item Short-Form Health Survey physical functioning scale (10 items) was found. The correlations of the LLFDI-CAT disability scale with the World Health Organization Disability Assessment Schedule 2.0 and the 10-Meter Walk Test were −.57 and −.53, respectively. The ICC (2,1) of the LLFDI-CAT function scale was .84, with a group-level reliability score of .85. The ICC (2,1) of the LLFDI-CAT disability scale was .76, with a group-level reliability score of .81. Limitations The high percentage of women in the study and the exclusion of older adults with recent joint replacement or hospitalization limit the generalizability of the results. Conclusions The Dutch LLFDI-CAT showed strong validity and high reliability when used to assess physical function and disability in older adults dwelling in the community.
