Long-Term Cognitive Aging Trajectories as Predictors of Daily Affect

Multiple-time scale studies provide new opportunities to examine how developmental processes evolving on different cadences are intertwined. Theories about age-related accumulation of stress suggest that long-term progressive loss of cognitive resources should manifest in and shape short-term daily affective experiences. Applying growth modeling and intraindividual variability methods to data obtained from 123 young-old (65-69 years, 51% women) and 47 very-old adults (85-88 years, 49% women) who provided 20+ year longitudinal data on Digit Symbol performance and 42-occasion momentary data about the emotions and stressors they experienced during everyday life (6 reports per day), we found that shallower long-term loss of cognitive performance was associated with less fluctuation in momentary positive affect, as well as less “spikiness” of and reactivity to stress. We discuss and present further results highlighting how mid-term processes surrounding age, gender roles, and health additionally contribute to and shape links between long-term and short-term dynamics of aging.

Interaction effect of coping self-efficacy and received support in daily life of hematopoietic cell transplant patient-caregiver dyads

Objectives According to the social cognitive theory, social support and self-efficacy may interact with each other i.e. compete or account jointly for better adaptation. This study examined the nature of the interaction between coping self-efficacy and received social support in daily lives of patient-caregiver dyads after cancer treatment. We tested whether the effect of daily fluctuations in coping self-efficacy and received support on daily affect was synergistic (positive jointed effect), compensatory (positive competing effect), or interference (negative competing effect). Design A dyadic daily-diary study conducted for 28 days after hospital discharge following hematopoietic cell transplantation. Methods Coping self-efficacy, received support, and positive and negative affect were measured in 200 patient-caregiver dyads. The analysis was based on the actor-partner interdependence moderation model using multilevel structural equation modeling. Results Statistically significant effect of interaction between daily coping self-efficacy and received support on negative affect was found, although only in the caregivers. In that group, higher daily received support compensated for lower daily coping self-efficacy but had a negative effect when coping self-efficacy was significantly higher than typical. Also, direct beneficial effects of higher daily coping self-efficacy and received support on caregiver positive affect were found. In the patients, higher daily coping self-efficacy was directly associated with better daily affect. Conclusions Diverse effects of daily coping self-efficacy and received social support were found—the interference effect in the caregivers and the main effect of coping self-efficacy in the patients. Higher daily coping self-efficacy and optimal received social support may provide resilience against affect disturbance after cancer treatment.

Perceived daily sleep need and sleep debt in adolescents: associations with daily affect over school and vacation periods

Study Objectives To describe trajectories of perceived daily sleep need and sleep debt, and examine if cumulative perceived sleep debt predicts next-day affect. Methods Daily sleep and affect were measured over 2 school weeks and 2 vacation weeks (N=205, 54.1% females, M±SDage = 16.9±0.87 years). Each day, participants wore actigraphs and self-reported the amount of sleep needed to function well the next day (i.e., perceived sleep need), sleep duration, and high- and low-arousal positive and negative affect (PA, NA). Cumulative perceived sleep debt was calculated as the weighted average of the difference between perceived sleep need and sleep duration over the past 3 days. Cross-lagged, multilevel models were used to test cumulative sleep debt as a predictor of next-day affect. Lagged affect, day of the week, study day, and sociodemographics were controlled. Results Perceived sleep need was lower early in the school week, before increasing in the second half of the week. Adolescents accumulated perceived sleep debt across school days and reduced it during weekends. On weekends and vacations, adolescents self-reported meeting their sleep need, sleeping the amount, or more than the amount of sleep they perceived as needing. Higher cumulative actigraphy sleep debt predicted higher next-day high arousal NA; higher cumulative diary sleep debt predicted higher NA (regardless of arousal), and lower low arousal PA the following day. Conclusion Adolescents experienced sustained, cumulative perceived sleep debt across school days. Weekends and vacations appeared to be opportunities for reducing sleep debt. Trajectories of sleep debt during vacation suggested recovery from school-related sleep restriction. Cumulative sleep debt was related to affect on a daily basis, highlighting the value of this measure for future research and interventions.

149 Perceived sleep need, cumulative sleep deficit, and associations with daily affect in adolescents: 28 days over school & vacation

Introduction This study aimed to describe trajectories of daily perceived sleep need and sleep deficit across 28 consecutive days, and examine if cumulative sleep deficit predicts next-day affect. Methods Daily sleep and affect were measured over 2 weeks of school and 2 weeks of vacation in 205 adolescents (54.1% females, Mage = 16.9 years). Each day, participants completed actigraphy and self-reported the amount of sleep needed to function well the next day (i.e., perceived sleep need), sleep duration, and high- and low-arousal positive and negative affect. Cumulative actigraphy and diary sleep deficit were calculated as difference between perceived sleep need and sleep duration, weighted by sleep deficit over the past 3 days. Cross-lagged, multilevel models were used to test cumulative sleep deficit as a predictor of next-day affect. Lagged affect, day of the week, study day, and sociodemographics were controlled. Results Perceived sleep need was lower early in the school week, before increasing in the second half of the week. Adolescents accumulated sleep deficit across school days and reduced it during weekends. During weekends and vacations, adolescents’ self-reported, but not actigraphy sleep duration, met perceived sleep need. Higher cumulative actigraphy sleep deficit predicted higher next-day high arousal negative affect; higher cumulative diary sleep deficit predicted higher negative affect (regardless of arousal), and lower low arousal positive affect the following day. Conclusion Adolescents experienced sustained cumulative sleep deficit across school days, and whilst non-school nights appeared to be opportunities for reducing sleep deficit. Trajectories of sleep deficit during vacation suggested recovery from school-related sleep restriction. Cumulative sleep deficit was related to affect on a daily basis, highlighting the value of this measure for future research and interventions. Support (if any):
