Charting everyday activities in later life: Study protocol of the mobility, activity, and social interactions study (MOASIS).

Prominent theories of aging emphasize the importance of resource allocation processes as a means to maintain functional ability, well-being and quality of life. Little is known about which activities and what activity patterns actually characterize the daily lives of healthy older adults in key domains of functioning, including the spatial, physical, social, and cognitive domains. This study aims to gain a comprehensive understanding of daily activities of community-dwelling older adults over an extended period of time and across a diverse range of activity domains, and to examine associations between daily activities, health and well-being at the within- and between-person levels.

Future time perspective and affect in daily life across adulthood and old age: Findings from two micro-longitudinal studies.

Objective: Future time perspective (FTP) refers to individuals' perceptions of the future as either open-ended or limited. Despite well-documented individual differences in FTP across the adult life span, little is known about short-term variations of FTP within individuals and the within-person associations between FTP and affective experiences.

Method: Study 1 used data from a daily diary study over 10 days (N = 564) with a wide age range across the adult life span (M = 48.

Intra- and interindividual differences in the within-person coupling between daily pain and affect of older adults.

The bidirectional interplay between chronic pain and negative affect is well-established in patient samples. However, less is known about the day-to-day relationship between pain and affect of older adults without severe illnesses and to what extent this association differs within and between individuals. A total of 224 participants (M = 77.

Personality trait predictors and mental well-being correlates of exercise frequency across the academic semester.

Rationale: Regular exercise is frequently recommended as a means of combating the negative effects of stress on mental health. But, among college students, exercise frequency remains below recommended levels.

Objective: To better understand exercising behaviors in college students, we examined how exercise patterns change across an academic semester and how these changes relate to personality traits and mental well-being.

Emotion Regulation, Subjective Well-Being, and Perceived Stress in Daily Life of Geriatric Nurses.

This daily diary study examined the within-person coupling between four emotion regulation strategies and both subjective well-being and perceived stress in daily life of geriatric nurses. Participants ( = 89) described how they regulated their emotions in terms of cognitive reappraisal and suppression. They also indicated their subjective well-being and level of perceived stress each day over 3 weeks.

Self-reported versus GPS-derived indicators of daily mobility in a sample of healthy older adults.

In light of novel opportunities to use sensor data to observe individuals' day-to-day mobility in the context of healthy aging research, it is important to understand how meaningful mobility indicators can be extracted from such data and to which degree these sensor-derived indicators are comparable to corresponding self-reports. We used sensor (GPS and accelerometer) and self-reported data from 27 healthy older adults (≥67 years) who participated in the MOASIS project over a 30-day period. Based on sensor data we computed three commonly used daily mobility indicators: life space (LS), travel duration using passive (i.
