Reliability and Validity of the Function Impairment Screening Tool in Chinese Older Adults

Background: Physical function gradually decreases with age in older adults, affecting their independence and quality of life and leaving them prone to adverse outcomes. Despite the importance of assessing function for older adults, most studies have focused on disability and paid less attention to functional impairment. Thus, given the lack of valid and practical methods for evaluating functional impairment for older adults, we developed the function impairment screening tool (FIST) using the Delphi method.Objective: This study aimed to evaluate the reliability and validity of the FIST in Chinese older adults.Methods: A total of 489 participants aged 60 years or older, and who had completed the FIST were included. A subgroup of 50 participants completed the FIST a second time, 1 week after the first round, and the test–retest reliability was evaluated using the intraclass correlation coefficient (ICC). Reliability was tested using Cronbach's alpha. Validity was examined using exploratory factor analysis. Criterion-related validity was assessed using correlations between the FIST and the Barthel Index activities of daily living (ADL), Lawton, and Brody instrumental activities of daily living (LB-IADL).Results: The Cronbach's alpha coefficient for the FIST was 0.930 (P < 0.001). The test–retest reliability was good, with an ICC of 0.928 (95% confidence interval [0.874, 0.960]). Exploratory factor analyses revealed one factor accounting for 60.14% of the scale's variance and the load values of every item were >0.4 (0.489–0.872). The correlation coefficient was 0.572 (P < 0.001) between the FIST score and ADL, and was 0.793 (P < 0.001) between the FIST score and IADL. The FIST score was positively correlated with walking speed (r = 0.475, P < 0.001) and grip strength (r = 0.307, P < 0.001), and negatively correlated with age (r = −0.588, P < 0.001) and Fried frailty phenotype (r = −0.594, P < 0.001).Conclusion: The FIST is a reliable and valid instrument for assessing physical function impairment in older adults.

Linguistic, reliable, and valid secondary efficacy measures are important in clinical settings and studies. The aim of the study is to report test–retest reliability and construct validity of Turkish version of Myasthenia Gravis-Activities of Daily Living Scale (MG-ADL-T) in Myasthenia Gravis (MG) patients. Fifty-two ocular and generalized individuals with MG, applying to rehabilitation center, were included in the study. MG-ADL-T, MG quality-of-life questionnaire (MG-QoL), MG composite (MGC), quantitative MG score (QMGS), and pulmonary function test were administered. Reliability was assessed with intraclass correlation coefficient (ICC) and Cronbach’s alpha. Spearman correlation test and receiver operating characteristic (ROC) analysis were performed for construct validity. MG-ADL-T had fair internal consistency (Cronbach’s α = .67), excellent test–retest reliability (ICC = 0.96) and moderate construct validity (MG-QoL, r = 0.59; QMGS, r = .58; MGC, r = .68). MG-ADL, a unique scale that evaluates activities of daily living (ADL), has good test–retest reliability and construct validity in Turkish MG patients.

Abstract Background The aim of this study was to examine the trends in impairment regarding activities of daily living (ADL), physical performance, and cognitive function among the oldest-old (those aged 80 and older) in China between 1998 and 2014. Methods We used data on 34,297 oldest-old individuals from the seven waves of the Chinese Longitudinal Healthy Longevity Study. We estimated age, period, and cohort effects on the prevalence of self-reported ADL impairment, tested physical performance and cognitive function impairment using the age–period–cohort model. Results Regarding age, the prevalence of ADL, physical performance, and cognitive function impairment were highest in the centenarians, but they did not increase with age in this population. Among the literate subgroup, the prevalence of cognitive impairment increased more rapidly with age than that in the illiterate subgroup. Regarding period, the prevalence of self-reported and tested physical impairment slowly increased between 1998 and 2014, but cognitive impairment remained stable. Regarding cohort, ADL impairment continuously decreased. However, physical and cognitive impairment remained stable after a brief decline in the early birth cohorts. Conclusions The results suggest that the age effect is still the most obvious effect regarding several types of functional impairment. The likelihood of a younger person experiencing functional impairment may not change significantly, but ADL is likely to be amenable to improvement resulting from improved medical and social care. Therefore, increased care for the oldest-old may considerably improve their quality of life, particularly regarding their basic ADL.

Test Retest Reliability

The Safety Assessment of Function and the Environment for Rehabilitation (SAFER Too)) was developed to assess people's abilities to manage functional activities safety within their homes. The results of a study to evaluate the instruments inter-rater and test-retest reliability and construct validity are reported. Reliability was evaluated using kappa for each dichotomous item. For inter-rater reliability, 59 of 66 items had acceptable reliability. For test-retest reliability, 63 of 70 items had acceptable kappa scores. For items where kappa could not be calculated because of limited variation between raters, percentage agreement was over 80%. For validity, higher SAFER Tool scores (that is, more safety problems) were hypothesised to be associated with less independence in activities of daily living (ADL) and instrumental activities of daily living (IADL) and more cognitive impairment. The correlation between SAFER Tool scores and cognitive impairment supported this hypothesis. The results of the correlations with ADL and IADL scores were less clear. This could be attributed to caregivers' assistance with activities which might have reduced risk, and generally limited variation in ADL scores. The reliability results from this study are positive. Further research to assure the SAFER Tools validity and predictive ability are needed.

Background and Purpose: The purpose of this study is to test the reliability and validity of the 3-item Useful Depression Screening Tool (UDST) for use with older adults in congregate living settings. Methods: There were 176 residents of senior housing or assisted living who completed the UDST. Rasch analysis and test criterion relationships with pain, physical activity, and depression diagnosis were used to determine validity. Test–retest reliability was conducted with 29 senior housing residents. Results: Rasch analysis demonstrated good fit of all items to the concept of depression. Criterion validity was supported, F(5) = 14.17, p < .001. Test–retest showed no significant differences in UDST scores over time (p = .29). Conclusions: The findings provide support for the validity and reliability of the UDST for use with older adults in congregate living settings.

Abstract BackgroundRural-urban inequalities in health among older adults in China have not been extensively studied from the national perspective. In particular, studies have not taken into account combinations of Hukou (household registration system in China) and actual residence, which may be important so as not to underestimate rural-urban differences. This study investigates rural-urban inequalities in prevalence of poor self-rated health, self-reported functional disabilities and depression among Chinese older adults in 2011 and 2015, and analyses sociodemographic determinants of rural-urban inequalities in self-reported health outcomes. MethodsData from the nationwide China Health and Retirement Longitudinal Study (CHARLS), on older adults aged 60 years and above in CHARLS 2011 and CHARLS 2015 were used. Only rural residents with rural Hukou and urban residents with urban Hukou were included. Sociodemographic factors, including age, sex, marital status, living arrangement, living near children, educational level and income were studied. Self-Rated Health (SRH) was assessed with a single question. Basic Activities of Daily Living (BADLs) and Instrumental Activities of Daily Living (IADLs) were used to measure self-reported functional abilities. The 10-item version of the Center for Epidemiologic Studies Depression Scale was used to measure self-reported depression. ResultsRural respondents had poorer socioeconomic status and higher prevalence of poor SRH, functional disabilities and depression than urban respondents. The levels of functional disabilities, both BADLs and IADLs, were similar in 2011 and 2015, while the prevalence of poor SRH and self-reported depression was lower in 2015, both among rural and urban respondents. Impairments increased with age and appeared at younger age among rural respondents compared to urban respondents. Being female, unmarried, with low educational level and low income increased the odds ratios of reporting poor SRH, functional disabilities and depression. Sensitivity analyses using only Hukou registration resulted in underestimation of rural-urban differences. ConclusionsThere were large rural-urban inequalities in poor SRH, self-reported functional disabilities and depression that were closely related to rural-urban differences in educational level and income.
