The interplay between perceived fatigability, intrinsic capacity and physical activity: network analysis in a British birth cohort study.

Background: Fatigability-an individual's susceptibility to fatigue when performing standardized activities-may arise from diminished functional reserves and contribute to reduced physical activity levels, potentially reinforcing the disablement process. In this study, we used network analysis to examine the associations among physical and mental fatigability, different domains of intrinsic capacity (IC), and physical activity (PA). Additionally, we investigated whether fatigability mediates the association between IC and PA.

Identifying intervention targets in the COVID-19 pandemic-related psychopathological network among adolescents: A simulating intervention study.

Objective: Network approaches to the pandemic-related psychopathology could help identify the effective targets for interventions in adolescents. However, previous studies involved only limited forms of psychopathology related to stress and trauma and relied on the traditional centrality analysis. This study aimed to identify more effective intervention targets of pandemic-related psychopathological symptoms in a large-scale sample of adolescents using a newly developed network-based simulation intervention technique.

Temporal dynamics of perceived self-reliance and psychiatric symptoms in older adults: applying dynamic time warping to longitudinal cohort data.

Objectives: Contemporary public health and care policies expect that promoting self-reliance can help older adults prevent or recover from morbidity, including psychiatric disorders. We sought to clarify the role of self-reliance dynamics in developing and recovering from psychiatric symptoms throughout the aging process.

Method: We used dynamic time warping to analyze the temporal ordering of within-person changes in five self-reliance indicators (three self-efficacy dimensions, mastery, self-esteem) and psychiatric symptoms in  = 1968 participants aged 55+ in the Longitudinal Aging Study Amsterdam, measured up to ten times across up to 30 years.

Risk perception, barriers, and working safely with silica dust in construction: a psychological network approach.

Background: In the construction industry workers are frequently exposed to hazardous substances. To explore and describe construction workers' barriers and motives to (not) work safely with hazardous substances, we examined their perspectives on the health risks, perceived barriers, and intention to use preventive measures with regard to silica dust. Specifically, we studied perspectives on the use of face masks, dust collection on power tools, and using a vacuum cleaner instead of a broom.

Adopting a complex systems approach to functional ageing: bridging the gap between gerontological theory and empirical research.

Functional ageing, related to but distinct from biological and environmental systems, is defined as the changes in physical, psychological, cognitive, and social functioning, as well as behavioural factors of individuals as they age. In this Personal View, we propose that a complex systems perspective to functional ageing can show how outcomes such as quality of life and longevity, and success in prevention and treatment, emerge from dynamic interactions among these domains, rather than from single causes. We support this view in three ways.

Bouncing back from life's perturbations: Formalizing psychological resilience from a complex systems perspective.

Experiencing stressful or traumatic events can lead to a range of responses, from mild disruptions to severe and persistent mental health issues. Understanding the various trajectories of response to adversity is crucial for developing effective interventions and support systems. Researchers have identified four commonly observed response trajectories to adversity, from which the resilient is the most common one.

A Network Approach to Compliance: A Complexity Science Understanding of How Rules Shape Behavior.

Unlabelled: To understand how compliance develops both in everyday and corporate environments, it is crucial to understand how different mechanisms work together to shape individuals' (non)compliant behavior. Existing compliance studies typically focus on a subset of theories (i.e.

Reporting standards for psychological network analyses in cross-sectional data.

Statistical network models describing multivariate dependency structures in psychological data have gained increasing popularity. Such comparably novel statistical techniques require specific guidelines to make them accessible to the research community. So far, researchers have provided tutorials guiding the of networks and their accuracy.

Intervening on psychopathology networks: Evaluating intervention targets through simulations.

Identifying the different influences of symptoms in dynamic psychopathology models may hold promise for increasing treatment efficacy in clinical applications. Dynamic psychopathology models study the behavioral patterns of symptom networks, where symptoms mutually enforce each other. Interventions could be tailored to specific symptoms that are most effective at lowering symptom activity or that hinder the further development of psychopathology.

The Mental Health Ecosystem: Extending Symptom Networks With Risk and Protective Factors.

Inspired by modeling approaches from the ecosystems literature, in this paper, we expand the network approach to psychopathology with risk and protective factors to arrive at an integrated analysis of resilience. We take a complexity approach to investigate the multifactorial nature of resilience and present a system in which a network of interacting psychiatric symptoms is targeted by risk and protective factors. These risk and protective factors influence symptom development patterns and thereby increase or decrease the probability that the symptom network is pulled toward a healthy or disorder state.

Argentinian Mental Health During the COVID-19 Pandemic: A Screening Study of the General Population During Two Periods of Quarantine.

Background: Due to the COVID-19 pandemic, Argentina has been under mandatory quarantine. We have aimed to investigate the state of mental health of the Argentine population and the behaviours adopted to cope with mental distress during quarantine.

Method: An online survey was conducted using a probabilistic sampling technique and stratified according to the geographic regions of the country.

Deconstructing and Reconstructing Resilience: A Dynamic Network Approach.

Resilience is still often viewed as a unitary personality construct that, as a kind of antinosological entity, protects individuals against stress-related mental problems. However, increasing evidence indicates that maintaining mental health in the face of adversity results from complex and dynamic processes of adaptation to stressors that involve the activation of several separable protective factors. Such resilience factors can reside at biological, psychological, and social levels and may include stable predispositions (such as genotype or personality traits) and malleable properties, skills, capacities, or external circumstances (such as gene-expression patterns, emotion-regulation abilities, appraisal styles, or social support).
