Daily Rumination Among Older Men and Women: The Role of Perceived Family and Nonfamily Social Partner Life Stress

OBJECTIVES

Women tend to ruminate more than men, and are generally more hypervigilant to the emotions of others in order to maintain positive social ties. Thus, compared to men, women may ruminate more when their social partners have greater life stresses. However, the literature on stressful events typically focuses on individuals' experiences and perceptions of stressors experienced by specific social ties such as spousal partners and adult children. The purpose of this study was to examine links between perceptions of a broad array of family and nonfamily social partner stresses and daily rumination among older men and women.

METHODS

Adults aged 65 and older (N = 293, 55% women) completed baseline assessments of family and nonfamily life stressors and 5-6 consecutive nightly assessments regarding rumination, interpersonal tensions, worries, and support provision.

RESULTS

Multilevel structural equation models revealed that perceptions of greater family and nonfamily life stressors were associated with greater rumination. The links between family stress and rumination varied by gender: family stress was related to greater rumination among women and not men. Moreover, among women, family and nonfamily stress-rumination links were accounted for by greater daily worries about others, and among men, the nonfamily stress-rumination link was due to greater interpersonal tensions as well as daily worries.

DISCUSSION

These findings may be due in part to gender role socialization and women's greater kin-keeping and investment in family ties.

The Associations Between Daily Activities and Affect: a Compositional Isotemporal Substitution Analysis

BACKGROUND

Daily activities are associated with affective experiences. A 24-h day can be separated into five mutually exclusive activity types: sleep, awake in bed, moderate-to-vigorous physical activity (MVPA), light-intensity physical activity (LIPA), and sedentary behavior (SB). Most research has examined these activities independently and not collectively, yet increased time in one activity must be offset by decreasing other activities. Using compositional isotemporal substitution analyses, this study examined the associations between time spent in daily activities and affect, including both high and low arousal positive and negative affect.

METHOD

Across three separate studies, daily activities and affect were measured throughout 7-15 days (M_days = 10) in 361 healthy community adults (72.5% females, M_age = 22.79 years). Activities were objectively assessed using accelerometry and self-reported affect was assessed using repeated ecological momentary assessments. Minutes spent in each activity and affect values across the three studies were averaged for each participant.

RESULTS

Longer sleep duration at the expense of time awake in bed was associated with lower high arousal negative affect (e.g., nervousness, b =  - 0.24, p = .007). More MVPA at the expense of LIPA or SB was associated with higher high arousal positive affect (e.g., happiness, b = 0.35, p = .027). Activity composition was not associated with low arousal positive or negative affect (all p ≥ .06).

CONCLUSION

Associations between 24-h activity composition and affect differed based on types of activities, types of affect, and the interrelationships between activities within the composition. Findings can aid interventions to develop integrated guidance on the optimal activity patterns for mental health.
