Positive mental health, positive affect and suicide ideation

International Journal of Clinical and Health Psychology, 2019
Positive mental health (PMH) has been shown to confer resilience against suicide ideation. However, the mechanisms underlying the positive effect of PMH on suicide ideation/behavior are largely unknown. The current study aimed to determine whether positive affect mediates the association between PMH and suicide ideation.A total of 150 adult outpatients

Positive affect and sleep: A systematic review [PDF]

Sleep Medicine Reviews, 2017
A sizeable literature has implicated sleep in the phenomenological experience of various mood disorders, vulnerability to psychopathology, and overall poor psychological functioning. By contrast, positive affective states (e.g., joy, happiness, vigor, positive mood) that may contribute to sleep have been understudied.

Positive affect treatment targets reward sensitivity: A randomized controlled trial.

Journal of Consulting and Clinical Psychology, 2023
OBJECTIVE Determine whether a novel psychosocial treatment for positive affect improves clinical status and reward sensitivity more than a form of cognitive behavioral therapy that targets negative affect and whether improvements in reward sensitivity ...

Positive leadership and employee engagement: The roles of state positive affect and individualism-collectivism

Current Psychology, 2021
Drawing upon broaden-and-build theory, this study examined the influence of positive leadership on employee engagement through the mediating role of employees’ state positive affect and the moderating effect of individualism-collectivism orientation in a

Association between real-world experiential diversity and positive affect relates to hippocampal-striatal functional connectivity

Nature Neuroscience, 2020
Experiential diversity promotes well-being in animal models. Here, using geolocation tracking, experience sampling and neuroimaging, we found that daily variability in physical location was associated with increased positive affect in humans. This effect

Reduced positive affect on days with stress exposure predicts depression, anxiety disorders, and low trait positive affect 7 years later.

Journal of Abnormal Psychology, 2020
Positive emotions serve important functions for mental health. Susceptibility to reduced positive emotions in the context of stress may increase risk for poor mental health outcomes, including anxiety and depressive disorders and low overall levels of ...

Positive Affect and Health: What Do We Know and Where Next Should We Go?

Annual Review of Psychology, 2019
Positive affect (PA) is associated with better health across a wide range of physical health outcomes. This review reflects on why the study of PA is an essential component of our understanding of physical health and expands on pathways that connect ...

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada

Population Ecology, EarlyView.
We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

Network topology drives population temporal variability in experimental habitat networks

Population Ecology, EarlyView.
Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

occumb: An R package for site occupancy modeling of eDNA metabarcoding data

Population Ecology, EarlyView.
This study introduces a new R package, occumb, for the convenient application of site occupancy modeling using environmental DNA (eDNA) metabarcoding data. We outline a data analysis workflow, including data setup, model fitting, model assessment, and comparison of potential study settings based on model predictions, all of which can be performed using
