Stress-buffering pattern of positive events on adolescents: An exploratory study based on social networks

Life satisfaction components and all-cause and cause-specific mortality: A large prospective cohort study

BACKGROUND

Which life satisfaction components could be a target of positive psychological interventions for longevity is largely unknown. We aimed to investigate association of the composite measure of life satisfaction and its individual components with mortality.

METHODS

This cohort study included UK Biobank participants who responded to questions concerning five components of life satisfaction at baseline. We generated a composite score representing overall life satisfaction, ranging from 0 (lowest) to 5 (highest). The outcomes were all-cause and cause-specific mortality. We used multivariable Cox regression to estimate hazard ratios (HR) for the associations of interest.

RESULTS

Among 165,842 eligible participants, 12,261 all-cause deaths were observed over a median of 12.9-year follow-up. Overall life satisfaction was inversely associated with all-cause mortality (adjusted HR 0.94 [95% CI: 0.93-0.95] per 1 score increment). Health satisfaction showed the strongest association with all-cause mortality, with a fully adjusted HR of 0.52 (95% CI: 0.49-0.55) for high/extreme satisfaction and 0.63 (95% CI: 0.59-0.66) for moderate satisfaction, compared with unsatisfaction (P-trend<0.001), independent of other satisfaction components, regardless of physical health and sociodemographics. The association for family, friendship, work and financial satisfaction was attenuated when adjusted for other life satisfaction components. Similar findings were observed for cause-specific mortality.

LIMITATIONS

Observational study with single baseline measurement of life satisfaction precludes the ability to establish causal relationship.

CONCLUSIONS

Higher overall life satisfaction was associated with lower mortality. As the major contributor to lower mortality regardless of physical health and sociodemographics, health satisfaction could be an important target of positive psychological interventions for longevity.

Relationships Between Family Connectedness and Stress-Triggering Problems Among Adolescents: Potential Mediating Role of Coping Strategies

The aim of this study was to provide a better understanding of the mechanisms underlying the relationships between family connectedness, coping strategies, and stress-triggering problems in adolescents. To this end, it longitudinally examined the relationships between these three phenomena in a sample of New Zealand adolescents. Data were the three waves of the Youth Connectedness Project, in which 1,774 adolescents aged 10-17 completed a self-report survey three times at one-year intervals. Using random intercept longitudinal mediation path models, we tested whether and to what extent different coping strategies at T2 functioned as mediators between family connectedness at T1 and stress-triggering problems at T3. As predicted, statistical analyses indicated that family connectedness negatively predicted stress-triggering problems over time, and we found that maladaptive coping, but not adaptive coping, significantly mediated this relationship. This result suggests that family connectedness predicted a reduction in maladaptive coping one year later, and this lower level of maladaptation predicted a reduction in stress-triggering problems a subsequent year later. These and other related findings are important as they highlight several mechanisms shaping unfolding problematic situations experienced by adolescents. Contributions of the results to the existing body of knowledge about adolescents' stress and coping strategies are discussed, as well as their clinical implications for the prevention or reduction of stress experienced by adolescents.

Positive life experiences and mortality: Examination of psychobiological pathways

INTRODUCTION AND RATIONALE

Positive life experiences are potentially-rewarding events and behaviors, such as social and romantic interactions, experiences of relaxation and physical comfort, time spent in nature, and other leisure activities. To date, there is limited evidence linking positive life experiences to long-term health outcomes.

OBJECTIVE AND METHODS

The current study used data from N = 1243 participants in the Midlife Development in the US Study Biomarker Project to examine whether greater frequency of a range of different positive experiences and greater level of enjoyment of these experiences was linked to survival over a 12- to-16-year period in Cox proportional hazards models. The potential mediating roles of positive affect, depression, perceived stress, and an allostatic load index of physiological dysregulation in these associations were also examined.

RESULTS

Greater frequency of positive experiences and greater enjoyment of positive experiences were both associated with a reduced hazard of mortality over the 12- to 16-year period. Models assessing a single mediator showed that both associations were mediated by decreased depression and decreased perceived stress, but not by positive affect or allostatic load. In supplementary multi-mediation models, depression was the only significant mediator of the frequency-survival and enjoyment-survival associations.

CONCLUSIONS

Positive life experiences may confer long-term survival benefits, partially through lessening depressive symptomatology.

Getting Social

Knowledge acquired by end users through their social networks facilitates optimal use of a newly implemented enterprise system. Existing research has conceptualized end users as being the only actors within such networks. Knowledge ties between actors have been treated as unidimensional. The actor-network theory emphasizes the role of all actors in influencing networking outcomes; hence, this study proposes an expanded multimodal social network that includes four institutionally mandated knowledge actors: the technology champions, the help desk, the service desk, and the shared inbox. Knowledge ties are treated as bidimensional through incorporating both technical and business process knowledge. Data collected from an enterprise resource planning system implementation validated this approach; end users sourced knowledge from other end users and the institutionally mandated network actors based on contextual requirements. End user performance outcomes were significantly associated with knowledge source and knowledge dimension.
