The Impact Of Psychological Strengths On Veteran Populations' Mental Health Trajectories During The Covid-19 Pandemic, Amanda Mccleery, Jonathan K Wynn, Derek M Novacek, Eric A Reavis, Damla Senturk, Catherine A Sugar, Jack Tsai, Michael F Green

Faculty, Staff and Student Publications

Purpose: Mental health trajectories during the COVID-19 pandemic have been examined in Veterans with tenuous social connections, i.e., those with recent homelessness (RHV) or a psychotic disorder (PSY), and in control Veterans (CTL). We test potential moderating effects on these trajectories by psychological factors that may help individuals weather the socio-emotional challenges associated with the pandemic (i.e., 'psychological strengths').

Methods: We assessed 81 PSY, 76 RHV, and 74 CTL over 5 periods between 05/2020 and 07/2021. Mental health outcomes (i.e., symptoms of depression, anxiety, contamination concerns, loneliness) were assessed at each period, and psychological strengths (i.e., a composite score based …

Predicting Suicidality In Late-Life Depression By 3d Convolutional Neural Network And Cross-Sample Entropy Analysis Of Resting-State Fmri, Chemin Lin, Chih-Mao Huang, Wei Chang, You-Xun Chang, Ho-Ling Liu, Shu-Hang Ng, Huang-Li Lin, Tatia Mei-Chun Lee, Shwu-Hua Lee, Shun-Chi Wu

Faculty, Staff and Student Publications

Background: Predicting suicide is a pressing issue among older adults; however, predicting its risk is difficult. Capitalizing on the recent development of machine learning, considerable progress has been made in predicting complex behavior such as suicide. As depression remained the strongest risk for suicide, we aimed to apply deep learning algorithms to identify suicidality in a group with late-life depression (LLD).

Methods: We enrolled 83 patients with LLD, 35 of which were non-suicidal and 48 were suicidal, including 26 with only suicidal ideation and 22 with past suicide attempts, for resting-state functional magnetic resonance imaging (MRI). Cross-sample entropy (CSE) analysis …

Daily Smartphone Use Predicts Parent Depressive Symptoms, But Parents' Perceptions Of Responsiveness To Their Child Moderate This Effect., Brandon T. Mcdaniel Phd, Sabrina Uva, Jessica Pater, Victor P. Cornet Ms, Michelle Drouin Phd, Jenny Radesky

Health Services and Informatics Research

INTRODUCTION: Smartphone use during caregiving has become increasingly common, especially around infants and very young children, and this use around young children has been linked with lower quality and quantity of parent-child interaction, with potential implications for child behavior, and parent-child attachment. To understand drivers and consequences of parent phone use, we were interested in the daily associations between parent phone use and depressed mood, as well as the potential for parent perceptions of their responsiveness toward their infant to alter the association between parent phone use and mood.

METHODS: In the present study, we explored associations between day-to-day changes …

Heavy Users, Mobile Gamers, And Social Networkers: Patterns Of Objective Smartphone Use In Parents Of Infants And Associations With Parent Depression, Sleep, Parenting, And Problematic Phone Use., Brandon T. Mcdaniel Phd, Jenny Radesky, Jessica Pater, Adam M Galovan, Annalise Harrison, Victor P. Cornet Ms, Lauren Reining, Alexandria Schaller, Michelle Drouin

Health Services and Informatics Research

Smartphone use during parenting is common, which may lead to distraction (also known as technoference). However, it is likely that some phone activities are less disruptive to parents and children. In this study, we explored smartphone use (via passive sensing across 8 days) within 264 parents of infants, measuring parents' application use on their phone (e.g., messaging, social media, mobile gaming, video chat) and phone use across contexts (e.g., during feeding and at bedtime). We utilized latent profile analysis to identify profiles of users, revealing five user types:

The Why, When, Where, How, And So What Of So-Called Rapidly Acting Antidepressants, Alan F Schatzberg, Sanjay J Mathew

Staff and Researcher Publications

Developing antidepressants that are not only more effective but are rapidly acting is the Holy Grail for psychiatry. We review multiple issues that arise in determining rapid responses in antidepressant trials. The current status of purportedly rapid acting agents is first reviewed. Then, a number of key questions/issues are addressed: Is there a unifying definition for rapid response across studies? Should rapid response criteria be based on required measurable effects on overall improvement? On specific symptoms such as psychomotor retardation, depressed mood, or anhedonia? In associated symptoms such as anxiety or insomnia? When should onset be considered rapid-by Day 3? …

Fitness Consequences Of Depressive Symptoms Vary Between Generations: Evidence From A Large Cohort Of Women Across The 20th Century, Christopher I Gurguis, Renée A Duckworth, Nicole M Bucaro, Consuelo Walss-Bass

Faculty, Staff and Student Publications

Depression has strong negative impacts on how individuals function, leading to the assumption that there is strong negative selection on this trait that should deplete genetic variation and decrease its prevalence in human populations. Yet, depressive symptoms remain common. While there has been a large body of work trying to resolve this paradox by mapping genetic variation of this complex trait, there have been few direct empirical tests of the core assumption that there is consistent negative selection on depression in human populations. Here, we use a unique long-term dataset from the National Health and Nutrition Examination Survey that spans …

Masculine Ideals And Health In Older Men: Findings From The Wisconsin Longitudinal Study, Shane D. Burns, Patricia Drentea

APC Fund

How do older men’s masculine ideals affect their health? Are masculine activities involved in this relationship? Masculine identity upholds beliefs about masculine enactment. These beliefs can be detrimental to men and can lead to behaviors that can put undue stress on them. We examine how masculine ideals are associated with health and depressive symptomatology in older men. We used 2011 data from the Wisconsin Longitudinal Study (n = 2,594) to investigate how masculine ideals inform older men’s health and how participation in masculine activities might shape these outcomes. Findings from this study illustrate that traditional masculine ideals are associated …

Childhood Unpredictability Is Associated With Increased Risk For Long- And Short-Term Depression And Anhedonia Symptoms Following Combat Deployment, Christopher Hunt, Meghan Vinograd, Laura M. Glynn, Elysia Poggi Davis, Tallie Z. Baram, Hal S. Stern, Caroline M. Nievergelt, Bruna Cuccurazzu, Cindy Napan, Dylan Delmar, Dewleen G. Baker, Victoria B. Risbrough

Psychology Faculty Articles and Research

High unpredictability has emerged as a dimension of early-life adversity that may contribute to a host of deleterious consequences later in life. Early-life unpredictability affects development of limbic and reward circuits in both rodents and humans, with a potential to increase sensitivity to stressors and mood symptoms later in life. Here, we examined the extent to which unpredictability during childhood was associated with changes in mood symptoms (anhedonia and general depression) after two adult life stressors, combat deployment and civilian reintegration, which were assessed ten years apart. We also examined how perceived stress and social support mediated and /or moderated …

Comparing The Effectiveness Of Mother-Focused Interventions To That Of Mother-Child Focused Interventions In Improving Maternal Postpartum Depression Outcomes: A Systematic Review, Divya Kumar, Waqas Hameed, Bilal Iqbal Avan

Community Health Sciences

Background: Most empirically researched interventions for postpartum depression (PPD) tend to target mothers' depression alone. Harmful effects of PPD on physical and mental health of both mother and child has led researchers to investigate the impact of interventions on PPD and child outcomes together. So far, the evidence is limited regarding how these interventions compare with those focusing only on mothers' depression. This review compares the effectiveness of PPD-improving interventions focusing only on mothers with those focusing on mother and child together.
Methods: Nine electronic databases were searched. Thirty-seven studies evaluating mother-focused (n = 30) and mother-child focused interventions (n …

Depression Screening Tool For Hysterectomy Patients, Dede C. Mihedji

Doctor of Nursing Practice (DNP) Projects

Abstract

Background: The prevalence of hysterectomies in the United States ranges from

5.1 to 5.8 per 1000 women (Harnod et al., 2018). A standardized screening tool for assessing

depression preoperatively could mitigate the worsening of postoperative depressive symptoms in patients scheduled for a hysterectomy.

Local Problem: Currently, there is no standard of practice to routinely screen for depression in preoperative patients scheduled for hysterectomy surgeries. However, as with any surgical intervention, there are risks of long-term complications. Studies have identified that a hysterectomy may increase the risk of cardiovascular events, menopause, depression, and other outcomes (Madueke-Laveaux et al., 2022). …

Cognitive Decline In Thrombotic Thrombocytopenic Purpura Survivors: The Role Of White Matter Health As Assessed By Mri., F Hannan, J Hamilton, C J Patriquin, K Pavenski, M T Jurkiewicz, L Tristao, A M Owen, P K Kosalka, S C L Deoni, J Théberge, J Mandzia, S H S Huang, J D Thiessen

Department of Medicine Publications

Immune-mediated thrombotic thrombocytopenic purpura (iTTP) is a rare condition caused by severe ADAMTS13 deficiency, leading to platelet aggregation and thrombosis. Despite treatment, patients are prone to cognitive impairment and depression. We investigated brain changes in iTTP patients during remission using advanced magnetic resonance imaging (MRI) techniques, correlating these changes with mood and neurocognitive tests. Twenty iTTP patients in remission (30 days post-haematological remission) were compared with six healthy controls. MRI scans, including standard and specialized sequences, were conducted to assess white matter health. Increased T1 relaxation times were found in the cingulate cortex (p < 0.05), and elevated T2 relaxation times were observed in the cingulate cortex, frontal, parietal and temporal lobes (p < 0.05). Pathological changes in these areas are correlated with impaired cognitive and depressive scores in concentration, short-term memory and verbal memory. This study highlights persistent white matter damage in iTTP patients, potentially contributing to depression and cognitive impairment. Key regions affected include the frontal lobe and cingulate cortex. These findings have significant implications for the acute and long-term management of iTTP, suggesting a need for re-evaluation of treatment approaches during both active phases and remission. Further research is warranted to enhance our understanding of these complexities.

Self-Reflections Through A Screen: Self-Identity, Social Media, And Psychological Well-Being, Jeremy J. Serio

Undergraduate Honors Thesis Collection

Social media use among emerging adults is assumed to be related to a variety of negative psychological outcomes and has, in recent years, become a widely studied phenomenon (Kim, 2017, Pew Research Center, 2018). Despite the widespread assumption, the results from empirical studies of the effects of social media use on mental health in this population have been inconsistent and inconclusive (Keles et al., 2020, Yang et al., 2021). Several meta-analyses (e.g., Keles et al., 2020) demonstrate these inconsistent results across studies and point to the need to consider individual difference factors when researching this issue. Different self-identity styles have …

A Sound Mind In A Sound Body: A Novel Concept Unravelling Heterogeneity Of Depression, Gabor Hullam, Zsofia Gal, Xenia Gonda, Tamas Nagy, Andras Gezsi, Isaac Cano, Sandra Van Der Auwera, Mikko Kuokkanen, Peter Antal, Gabriella Juhasz

School of Medicine Publications

Depression is a highly prevalent and debilitating condition, yet we still lack both in-depth knowledge concerning its etiopathology and sufficiently efficacious treatment options. With approximately one third of patients resistant to currently available antidepressants there is a pressing need for a better understanding of depression, identifying subgroups within the highly heterogeneous illness category and to understand the divergent underlying biology of such subtypes, to help develop and personalise treatments. The TRAJECTOME project aims to address such challenges by (1) identifying depression-related multimorbidity subgroups and shared molecular pathways based on temporal disease profiles from healthcare systems and biobank data using machine …

Evaluating The Effects Of Ketamine On Cognitive Flexibility In Rats Using A Probabilistic Reversal Learning Task, Anthony N. Nist

All Graduate Theses and Dissertations, Fall 2023 to Present

Depression is one of the most debilitating and widespread mental health conditions in the world today. Drugs that are traditionally prescribed to combat depression are flawed in several ways, and because of this, new treatments are needed. One drug that seems capable of overcoming the limitations of traditional antidepressants is ketamine. In clinical research, a single dose of ketamine can significantly reduce symptoms of depression quickly, its effects may last for weeks to months, and its side effects appear to be limited and relatively harmless. However, clinical research is ongoing, and more research is needed to fully understand ketamine's beneficial …
