Information Communication Technology as Instrumental Activities of Daily Living for Aging-in-Place in Chinese Older Adults With and Without Cognitive Impairment: The Validation Study of Advanced Instrumental Activities of Daily Living Scale.

Background: The capability in applying information communication technology (ICT) is crucial to the functional independence of older peoples of community living nowadays. The proper assessment of individuals' capability of ICT application is the corner stone for the future development of telemedicine in our aging population. Methods: With the recruitment of 300 participants of different functional and social background in home-living, hostel-living, and care-and-attention home living; and through assessing the ability of individuals in instrumental activities of daily living and cognitive assessments, this study aimed at capturing the content validity and construct validity of the Advanced Instrumental Activities of Daily Living (AIADL scale). In addition, this study assess the ability of older peoples in applying ICT and how the functional and social background affects their independence in aging-in-place. Results: The AIADL scale showed good test-retest reliability and good-to-excellent internal consistency. To determine if items of the AIADL scale measure various aspects of community living, exploratory factor analysis revealed a two-factor structure with "home living and management" and "community living". Validity analysis with the known-groups method showed a high overall accuracy of prediction of individuals' capability of independent living in the community. Conclusions: The AIADL scale is a valid and reliable instrument to assess the ability of older adults in handling ICT as part of their instrumental activities in daily living. The scale can reflect capability of older peoples in applying ICT. This instrument can serve as a reference in measuring readiness of individuals in receiving telemedicine and their ability of aging-in-place.

The Protective Impact of Telemedicine on Persons With Dementia and Their Caregivers During the COVID-19 Pandemic.

OBJECTIVES: Social distancing under the COVID-19 pandemic has restricted access to community services for older adults with neurocognitive disorder (NCD) and their caregivers. Telehealth is a viable alternative to face-to-face service delivery. Telephone calls alone, however, may be insufficient. Here, we evaluated whether supplementary telehealth via video-conferencing platforms could bring additional benefits to care-recipient with NCD and their spousal caregivers at home. PARTICIPANTS: Sixty older adults NCD-and-caregiver dyads were recruited through an activity center. DESIGN, INTERVENTION: The impact of additional services delivered to both care-recipient and caregiver through video conference (n = 30) was compared with telehealth targeted at caregivers by telephone only (n = 30), over 4 weeks in a pretest-post-test design. Interviews and questionnaires were conducted at baseline and study's end. MEASUREMENTS, RESULTS: Supplementary telemedicine had averted the deterioration in the Montreal Cognitive Assessment evident in the telephone-only group (ηp2 = 0.50). It also reversed the falling trend in quality of life observed in the telephone only group (QoL-AD, ηp2 = 0.23). Varying degrees of improvements in physical and mental health (Short-Form 36 v2), perceived burden (Zarit Burden Interview Scale) and self-efficacy (Revised Caregiving Self-Efficacy Scale) were observed among caregivers in the video-conferencing group, which were absent in the telephone-only group (ηp2 = 0.23-0.51). CONCLUSION: Telemedicine by video conference was associated with improved resilience and wellbeing to both people with NCD and their caregivers at home. The benefits were visible already after 4 weeks and unmatched by telephone alone. Video conference as the modus operandi of telehmedicine beyond the context of pandemic-related social distancing should be considered.

A randomized control trial of activity scheduling for caring for older adults with dementia and its impact on their spouse care-givers.

INTRODUCTION: Participating in meaningful activities is important for any individual's wellbeing. Activity scheduling enables older adults with dementia and their spouse caregivers to structure their activities in accordance with the things they value. METHODS: In examining the effectiveness of activity scheduling, this report details the results of a 12-week single-blinded randomized control trial using a parallel group experimental design. RESULTS: From August 2018 to August 2019, 100 community-dwelling older adults with mild to moderate dementia and their spouses completed this study. The experimental group (n = 50) practicing activity scheduling showed improvements than in control group (n = 50), with respect to alleviating the impact of the caregiving role, reducing the behavioural and psychological symptoms of dementia, decreasing the caring demand and generally improving the quality of life, with Cohen's d = .61, .45, .50 and 43 respectively. Moreover, there were significant differences between the groups indicated that over time, the experimental group showed an improvement with regard to alleviating the role of caring, with Cohen's d = .64, and alleviating disruptive and depressive behavior, with an effect size of .45 and .50 respectively. The number of caring hours needed dropped from 6.98 to 5.98 h in the experimental group. DISCUSSION & CONCLUSION: There were more activities that older adults with dementia and their spouse caregivers would like to do, and could participate in, than we had expected. Activity scheduling can facilitate their participation. This is a very important topic as non-pharmacological interventions are needed for this even-growing segment of the population.

Home-based evaluation of executive function (Home-MET) for older adults with mild cognitive impairment.

INTRODUCTION: Executive function helps older adults maintain their activities of daily living by making plans, setting goals, and carrying them out successfully. It is important for their independence in community living. METHODS: With a carefully match-group of 80 mild cognitive impaired with 80 health control subjects. The home-based evaluation of executive function (Home-MET) was validated in subjects' own living environment. RESULTS: This Home-MET showed significant correlation in the assessment of attention control that was assessing by Test of Everyday Attention (TEA) (r = .86, p < .01), with working memory that was assessed with Trail Making Test (TMT) (r = .72, p < .01), with inhibitory control that was assessing with Stroop Test (r = .86, p < .01), with individuals' functional disability was assessed by Chinese Disability Assessment of Dementia (CDAD) (r = .77, p < .01) and cognitive assessment was assessed by Hong Kong Montreal Cognitive Assessment (HK-MoCA) (r = .88, p < .01). By benchmarking with the validated performance-based executive function assessment, the Home-MET shows significant correlation (r = .92, p < .05) with the executive function test in a standard environment in hospital, i.e. the Chinese Multiple Errands Test (the Chinese-MET). The two-stage hierarchical linear regression model with backward method showed functional disability was a marginally significant predictor (p < .059) for the Home-MET with regression model showed with R2 = .93. CONCLUSION: Results indicated the Home-MET, can provide an objective measure of executive function for subjects with mild cognitive impairment in participants' own home environment.
