Mobile device use and the cognitive function and depressive symptoms of older adults living in residential care homes

Abstract

Background: With the fast-paced aging and increasing digitalization of society, there has been a growing interest in the effect of mobile device use on cognitive function and depression in older adults. However, research examining this issue among older adults in residential care homes (RCHs) is scant. Therefore, this study aimed to examine the impact of mobile device use on the cognitive function and depressive symptoms of older adults living in RCHs. Methods: A cross-sectional survey was conducted using a sociodemographic questionnaire, the Montreal Cognitive Assessment (MoCA) and the 15-item Geriatric Depression Scale (GDS-15). Results: A total of 235 senior residents (aged 82.58 ± 5.54) in four RCHs were surveyed. Users of mobile devices had a significantly higher total MoCA score (25.02 ± 4.14) and a significantly lower GDS-15 score (3.28 ± 2.74) than non-users (MoCA: 19.34 ± 5.21, GDS-15: 4.69 ± 2.90). Multivariate linear regression indicate that mobile device use is significantly associated with total MoCA score, six of the seven sub-scores (visuospatial abilities and execution functions, attention, language, abstraction, delayed recall, and orientation)(P < 0.05). Logistic regression showed that mobile device use was significantly associated with the level of depressive symptoms (OR = 0.458, 95%CI = 0.249-0.845). Conclusions: Use of mobile devices has a significant association with the cognitive function and depressive symptoms of older adults living in RCHs, and thus should be encouraged as a measure to maintain and improve cognition and prevent depression.

Predictors of Cognitive Function in Community-Dwelling Older Adults by Age Group: Based on the 2017 National Survey of Older Korean Adults

“…First, the most potent predictor of cognitive function in the young-old group was electronic device-based activities, which is in line with previous findings that older adults who use mobile devices demonstrate better cognitive functions [ 33 ] and that owning a computer or cell phone slows down the rate of cognitive decline [ 34 ]. A study that analyzed the predictors of cognitive function in older adults [ 35 ] also reported that electronic device-based activities were the strongest predictor of cognitive function in older adults.…”

Effectiveness of laptop-based versus smartphone-based videoconferencing interaction on loneliness, depression and social support in nursing home residents: A secondary data analysis

“…The lack of significant change in depressive symptoms for the smartphone-based videoconferencing group corresponds with the smartphone study of Tsai et al. 18 Although NH residents who are regular users of mobile devices such as smartphones have been shown to have lower levels of depressive symptoms than non-users, 32 the failure to detect a reduction in depressive symptoms might be due to the NH residents’ lack of familiarity with a smartphone.…”

Mobile Phone Use and Cognitive Impairment among Elderly Chinese: A National Cross-Sectional Survey Study

“…A 2016 survey in Xiamen in China showed 30% of adults aged 60+ years used smartphones, and more functions were positively associated with increased general and partial subdomain cognitive functions [ 10 ]. Another small-scale, cross-sectional survey in China showed association between the usage of mobile phone and cognitive function [ 11 ]. Since social contact and intellectual activities were both identified as protective factors of cognitive impairment [ 8 , 12 ], the mobile phone users may have better cognitive function due to minimized social isolation and enhanced cognitive skills.…”
