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., (© The Author(s) 2024.

Objectives: It is well established that daily perceived control is closely associated with lower negative affect (NA) among older adults. However, it is an open question whether control perceptions of one's partner are also uniquely associated with one's own NA., Method: To examine such associations in dyads of older long-term partners, we make use of data obtained 6 times a day over 7 consecutive days as participants went about their everyday lives (N = 87 couples; mean age = 75 years; mean relationship length = 46 years). Our multilevel actor-partner models for dyadic data analyses covary for relevant individual and couple differences in sociodemographic characteristics, self-reported physical health, and cognitive functioning., Results: Corroborating and extending earlier reports, results reveal that higher momentary perceived control was associated with lower NA. Most importantly, we found that higher momentary perceived control of the partner is additionally and uniquely associated with lower NA of the actor., Discussion: We discuss possible mechanisms and underlying pathways of how perceived control may help both partners downregulate their negative emotions in daily life. We close by considering conceptual and practical implications., (© The Author(s) 2018. Published by Oxford University Press on behalf of The Gerontological Society of America. All rights reserved.

Conceptual notions and empirical evidence suggest that the intraindividual correlation (iCorr) of positive affect (PA) and negative affect (NA) is a meaningful characteristic of affective functioning. PA and NA are typically negatively correlated within-person. Previous research has found that the iCorr of PA and NA is relatively stable over time within individuals, that it differs across individuals, and that a less negative iCorr is associated with better resilience and less vulnerability. However, little is known about how the iCorr of PA and NA relates to cognitive aging. This project examined how the association between PA and NA in everyday life is associated with long-term cognitive aging trajectories. To do so, we linked microlongitudinal data on PA and NA obtained on up to 33 occasions over 6 consecutive days with macrolongitudinal data on fluid and crystallized cognitive abilities obtained over 15 years from a subsample of Berlin Aging Study participants (N = 81, mean age at the microlongitudinal study = 81 years, range 73-98; 41% women). Over and above age, gender, education, overall levels of PA and NA, and number of health conditions, a less negative iCorr of PA and NA was associated with lower levels of cognitive ability and steeper cognitive declines, particularly for fluency and knowledge abilities. We discuss possible mechanisms for this finding and argue that a less negative iCorr of PA and NA may be indicative of deficits in emotional integration that are tied to changes in crystallized aspects of cognitive abilities., ((c) 2015 APA, all rights reserved).)
