The role of social interaction modality for well-being in older adults.

It is well-established that more frequent social interaction is associated with higher well-being across the lifespan. The present study examines the role of frequency of interactions via different modalities on older adults' weekly well-being during the COVID-19 pandemic, where people had to adapt their communication behavior and reduce in-person contact due to precautionary measures. We use data from 98 participants (age: M = 71, SD = 5), who documented their weekly frequency of communication via four interaction modalities as well as their loneliness, positive affect, and negative affect over up to 64 weeks. Results show that participants with overall higher frequency of face-to-face, telephone, and text-based interaction than others report higher levels of positive affect and lower levels of negative affect and loneliness than others. Participants report higher levels of well-being during weeks when they report more frequent face-to-face, telephone, and text-based interaction than their individual average. Unexpectedly, participants report higher levels of negative affect during weeks with more video call interaction. Some effects of social interaction frequency on affect and loneliness are higher for face-to-face interactions versus other modalities. In addition, interaction effects at within-person level indicate that the effects of weekly telephone and text-based interaction frequency on loneliness are stronger in weeks with relatively few face-to-face interactions. Taken together, our findings suggest that social interactions via different modalities contribute to well-being, but that face-to-face interactions have the biggest effect. In addition, there is some evidence that telephone and text-based interaction may play a compensatory role. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Routineness of Social Interactions Is Associated With Higher Affective Well-Being in Older Adults.

OBJECTIVES: Some research conceptualizes routineness of daily life as an indicator of cognitive vulnerability that would lead to lower well-being in older age, whereas other research expects routineness to give rise to more meaning and stability in life and thus to higher well-being. Further research is needed to understand routineness in older adults in relation to cognitive abilities and well-being. This study examined routineness of social interactions. METHODS: We examined data from an event-contingent experience sampling study with 103 Swiss community-dwelling older adults (aged 65 to 84 years). Participants completed in-lab cognitive assessments (reasoning, episodic memory, speed, and vocabulary) and reported their well-being (positive affect, negative affect, and life satisfaction). For more than 21 days, participants reported the time and context of their social interactions (including modality, partner type, and location). Routineness of social interactions was defined as social interactions that occurred at the same time of day over the study period. It was calculated using recurrence quantification analysis. RESULTS: Linear regressions showed that higher routineness of social interaction in general, of social interaction through the same modality, and of social interaction with the same partner type were associated with higher positive affect. Higher routineness of social interaction in general was associated with lower negative affect. Routineness of social interactions was not associated with life satisfaction or cognitive abilities. DISCUSSION: A routine social life may increase older adults' affective well-being. Results are discussed in the context of activity engagement and time use in older age.

Heart rate variability covaries with amygdala functional connectivity during voluntary emotion regulation.

The Neurovisceral Integration Model posits that shared neural networks support the effective regulation of emotions and heart rate, with heart rate variability (HRV) serving as an objective, peripheral index of prefrontal inhibitory control. Prior neuroimaging studies have predominantly examined both HRV and associated neural functional connectivity at rest, as opposed to contexts that require active emotion regulation. The present study sought to extend upon previous resting-state functional connectivity findings, examining task-related HRV and corresponding amygdala functional connectivity during a cognitive reappraisal task. Seventy adults (52 older and 18 younger adults, 18-84 years, 51% male) received instructions to cognitively reappraise negative affective images during functional MRI scanning. HRV measures were derived from a finger pulse signal throughout the scan. During the task, younger adults exhibited a significant inverse association between HRV and amygdala-medial prefrontal cortex (mPFC) functional connectivity, in which higher task-related HRV was correlated with weaker amygdala-mPFC coupling, whereas older adults displayed a slight positive, albeit non-significant correlation. Furthermore, voxelwise whole-brain functional connectivity analyses showed that higher task-based HRV was linked to weaker right amygdala-posterior cingulate cortex connectivity across older and younger adults, and in older adults, higher task-related HRV correlated positively with stronger right amygdala-right ventrolateral prefrontal cortex connectivity. Collectively, these findings highlight the importance of assessing HRV and neural functional connectivity during active regulatory contexts to further identify neural concomitants of HRV and adaptive emotion regulation.

Not "The More The Merrier": Diminishing Returns to Daily Face-To-Face Social Interaction Frequency for Well-Being in Older Age.

OBJECTIVES: While being socially active is beneficial for well-being in older age, it is unclear whether effects of social interactions on well-being indicate "the more the merrier" or if they have limits as individuals socialize more or less across different days. This study addressed diminishing returns to social interaction frequency for well-being. METHOD: We examined data from an event-contingent experience sampling study from 116 Swiss older adults (65 to 94 years old) over 21 days. Participants reported face-to-face social interactions once they occurred and daily well-being (i.e., positive and negative affect, loneliness) in the evenings. RESULTS: On average, participants had 2.09 face-to-face social interactions per day. Linear and quadratic effects from multilevel models conjointly indicated that a higher number of daily social interactions was associated with higher daily positive affect and lower daily negative affect and loneliness, but that well-being reached its peak at 2-3 times above participants' typical daily interaction frequency. Once these numbers were surpassed, the benefit of additional social interactions diminished. Additionally, participants who typically had fewer social interactions, were unmarried, lived alone, and had more health conditions showed stronger associations between daily social interaction frequency and well-being. DISCUSSION: Our findings suggest the benefits of social interactions on well-being exhibit diminishing returns. Social interactions may play a bigger role in older adults with less satiation for desire to belong and a limited future time perspective. We discuss these findings in terms of the belongingness hypothesis and the socioemotional selectivity theory.

Well-Being and Loneliness in Swiss Older Adults During the COVID-19 Pandemic: The Role of Social Relationships.

BACKGROUND AND OBJECTIVES: The current coronavirus disease 2019 (COVID-19) pandemic and social distancing measures are an extreme stressor that might result in negative emotional experiences and feelings of loneliness. However, it is possible that social relationships might have a protective effect. In the present study, we examine how the COVID-19 pandemic affected older adults' well-being and loneliness, and the role of structural and functional characteristics of social relationships. RESEARCH DESIGN AND METHODS: We use data from 99 older adults in Switzerland who participated (a) in a 3-week microlongitudinal study on social relationships and well-being in 2019 and (b) in a weekly online survey during 4 weeks of the COVID-19 lockdown. RESULTS: Our findings show that the global pandemic had substantial adverse effects on older adults' emotional well-being and loneliness. In addition, aspects of social relationships were related to loneliness both before and during the pandemic. Only one functional feature of social relationships (satisfaction with communication during the pandemic) buffered adverse effects of the major stressful event. DISCUSSION AND IMPLICATIONS: Although the social distancing measures during COVID-19 presented a major stressor for older adults' well-being and loneliness, being able to maintain social communication to a satisfactory level during that time reduced this effect. Therefore, enabling older adults to stay in touch with their social circle based on their personal preferences might reduce the impact that any future lockdown might have on their well-being.

Longitudinal change in executive function is associated with impaired top-down frontolimbic regulation during reappraisal in older adults.

Networks in the prefrontal cortex (PFC) that are important for executive function are also engaged in adaptive responding to negative events. These networks are particularly vulnerable to age-related structural atrophy and an associated loss of executive function, yet existing evidence suggests preserved emotion processing ability in ageing. Using longitudinally acquired data from a battery of cognitive tasks, we defined a metric for the rate of decline of executive function. With this metric, we investigated relationships between changes in executive function and emotion reappraisal ability and brain structure, in 34 older adults, using functional and structural MRI. During task-based fMRI, participants were asked to cognitively reappraise negatively valenced images. We hypothesised one of two associations with decreasing executive function over time: 1) a decreased ability to reappraise reflected in decreased PFC and increased amygdala activation, or 2) a neural compensation mechanism characterised by increased PFC activation but no differential amygdala activation. Structurally, for a decreased reappraisal ability, we predicted a decrease in grey matter in PFC and/or a decrease of white matter integrity in amygdala-PFC pathways. Neither of the two hypotheses relating to brain function were completely supported, with the findings indicating a steeper decline in executive function associated with both increased PFC and increased left amygdala activity when reappraising negative stimuli. In addition, white matter integrity of the uncinate fasciculus, a primary white matter tract connecting the amygdala and ventromedial areas of PFC, was lower in those individuals who demonstrated a greater decrease in executive function. These findings highlight the association of diminishing cognitive ability with brain structure and function linked to emotion regulation.

Internet Adoption in Older Adults: Findings from the Health and Retirement Study.

Being able to use the Internet is becoming increasingly important in today's digitized society. Evidence suggests that older adults are at risk of being left behind by technological developments. We examined Internet adoption in older adults in relation to sociodemographic, health, cognitive, social, and personality factors. We used data from the Health and Retirement Study (n = 5,949; 61 percent women; age: M = 72 years, standard deviation [SD] = 7; range = 50-105). Internet use was examined over an 8-year period. Predictors were assessed at baseline. We used a Cox proportional hazards model to examine how predictors were related to Internet adoption during the study period. Overall, 1,296 out of 5,949 participants (22 percent) reported starting to use the Internet during the study period. Our findings revealed that younger age, higher education, higher income, living with a partner, and better cognitive performance were associated with a higher likelihood of Internet adoption, whereas being Black was associated with a lower likelihood. Openness was associated with a higher likelihood of Internet adoption over the study period. Our findings add to the literature on the role of sociodemographic, cognitive, and health factors in older adults' Internet use. In addition, we show that personality also predicts older adults' Internet use.

Digitalization and the Social Lives of Older Adults: Protocol for a Microlongitudinal Study.

BACKGROUND: Digital technologies are increasingly pervading our daily lives. Although older adults started using digital technologies later than other age groups, they are increasingly adopting these technologies, especially with the goal of communicating with others. However, less is known about how online social activities are embedded in older adults' daily lives, how they complement other (offline) social activities, and how they contribute to social connectedness and well-being. OBJECTIVE: Data generated by this project will allow us to understand how older adults use digital communication in their daily lives to communicate with others, how this relates to well-being and social connectedness, and how communication using digital technologies differs from other types of communication depending on situational and individual characteristics. METHODS: Microlongitudinal data were collected from 120 older adults from German-speaking regions of Switzerland to examine these questions. Data collection took place from April 2019 to October 2019. Data collection took place over different time scales, including event-based (reporting all social interactions for 21 days), daily (well-being, loneliness, and technology use every evening for 21 days), hourly (cortisol assessments 6 times per day for 3 days), and baseline (relevant interindividual characteristics, including sociodemographics, health, technology use, personality, and cognitive performance) assessments. RESULTS: Data collection for this study was completed in November 2019. Participants reported an average of 96.35 interactions across the 21 days. Among the total 11,453 interactions, 5494 (47.97%) were face-to-face, and around 16% each were interactions by phone (1858, 16.16%), email (1858, 16.22%), and text message (1853, 16.18%). Otherwise, 246 (2.15%) of the interactions took place on social media, 96 (0.84)% were letters, and 54 (0.47%) of the interactions took place on videochat. CONCLUSIONS: Participants used a variety of modalities in their daily communication, including digital means such as text messages, email, and video calls. Further analysis will provide more detail as to the role that communication via digital media plays in older adults' daily lives.

Rethinking social relationships in old age: Digitalization and the social lives of older adults.

Interactions with technology have been shaping human society since its beginning. Recently, digitalization has pervaded all aspects of our lives and provided us with new ways to communicate with our social contacts and develop new social ties. We address how these changes shape the social lives of older adults today. Several factors may give rise to concerns that older adults today are at risk for social isolation, including demographic trends toward smaller families, or reduction of previous activities due to health limitations. At the same time, older adults today have access to new technologies that may enable them to overcome geographical distance and mobility barriers. First, based on models of technology adoption, we review research on digital technology use by older adults. Although older adults use technology at lower rates than other age groups, rates of (social) Internet use are increasing. However, sociodemographic disparities exist in access to technology. Second, we focus on 3 key questions and methodological directions for future research: (a) Does (social) Internet use contribute to more positive social experiences and well-being in old age? (b) What are future methodological directions in the study of social technology use in older adults? (c) Do digital technologies reshape the social experience in old age or do they reinforce existing preferences and behaviors? Addressing these questions will allow us to understand the effects of technology on older adults' daily lives and how this in turn affects multiple domains of functioning (e.g., well-being, cognitive function, physical health) in future generations.

Selective extinction through cognitive evaluation: Linking emotion regulation and extinction.

The extinction of a previously conditioned response can be modulated through cognitive processes, including feature-based information, and explicit instruction. Here, we introduce a selective extinction through cognitive evaluation (SECE) task in which information is cognitively evaluated on a trial-by-trial basis to ascertain the extinction contingencies. Participants were conditioned to expect an electric shock during the presentation of one of two letters (CS+/CS-). During the SECE task, the letters were presented within words belonging to two categories, one of which indicated safety (COG-_CS+ trials), while risk of shock was maintained for the other category (COG+_CS+ trials). Skin conductance responses indicated that participants reduced their response to COG-_CS+ trials compared to COG+_CS+ trials. Clusters in bilateral insula and anterior cingulate cortex showed activation for COG+_CS+ trials that was reduced for COG-_CS+ trials. A network of brain regions, including left inferior frontal gyrus, and bilateral temporal and parietal cortices showed greater activation for COG-_CS+ versus COG+_CS+ trials. This is consistent with the semantic processing and decision-making necessary to evaluate the trial contingencies. We compared activation in the SECE task to activation in a cognitive reappraisal task in which participants were asked to attend to, or regulate their emotional reactions to affective IAPS images. This task replicated prefrontal activation seen in previous reappraisal studies. A voxelwise conjunction analysis found no overlap between the cognitive reappraisal and the SECE task, but we did find evidence for common activation in follow-up ROI analyses, supporting the idea of common lateral prefrontal mechanisms involved in both processes.

What Is Going On Around Here? Intolerance of Uncertainty Predicts Threat Generalization.

Attending to stimuli that share perceptual similarity to learned threats is an adaptive strategy. However, prolonged threat generalization to cues signalling safety is considered a core feature of pathological anxiety. One potential factor that may sustain over-generalization is sensitivity to future threat uncertainty. To assess the extent to which Intolerance of Uncertainty (IU) predicts threat generalization, we recorded skin conductance in 54 healthy participants during an associative learning paradigm, where threat and safety cues varied in perceptual similarity. Lower IU was associated with stronger discrimination between threat and safety cues during acquisition and extinction. Higher IU, however, was associated with generalized responding to threat and safety cues during acquisition, and delayed discrimination between threat and safety cues during extinction. These results were specific to IU, over and above other measures of anxious disposition. These findings highlight: (1) a critical role of uncertainty-based mechanisms in threat generalization, and (2) IU as a potential risk factor for anxiety disorder development.

Altered engagement of autobiographical memory networks in adult offspring of postnatally depressed mothers.

Maternal depression is associated with increased risk for offspring mood and anxiety disorders. One possible impact of maternal depression during offspring development is on the emotional autobiographical memory system. We investigated the neural mechanisms of emotional autobiographical memory in adult offspring of mothers with postnatal depression (N=16) compared to controls (N=21). During fMRI, recordings of participants describing one pleasant and one unpleasant situation with their mother and with a companion, were used as prompts to re-live the situations. Compared to controls we predicted the PND offspring would show: greater activation in medial and posterior brain regions implicated in autobiographical memory and rumination; and decreased activation in lateral prefrontal cortex and decreased connectivity between lateral prefrontal and posterior regions, reflecting reduced control of autobiographical recall. For negative situations, we found no group differences. For positive situations with their mothers, PND offspring showed higher activation than controls in left lateral prefrontal cortex, right frontal pole, cingulate cortex and precuneus, and lower connectivity of right middle frontal gyrus, left middle temporal gyrus, thalamus and lingual gyrus with the posterior cingulate. Our results are consistent with adult offspring of PND mothers having less efficient prefrontal regulation of personally relevant pleasant autobiographical memories.
