learned helplessness

BACKGROUND: Climate change is the greatest threat to human health. Medical students, as future health-care workers, are important in promoting sustainable behaviours, which are strongly associated with individuals' emotional responses to climate change. At Würzburg University Hospital (Würzburg, Germany), a one-term optional course (40 learning units) about planetary health and two lectures within the curricular course Environmental Medicine were introduced in 2021. We aimed to examine the effects of these courses on the emotions and motivations of students in acting against climate change...

OBJECTIVE: : Environmental deprivation, a type of childhood maltreatment, has been reported to constrain the cognitive developmental processes such as associative learning and implicit learning, which may lead to functional and morphological changes in the ventral pallidum (VP) and pessimism, a well-known cognitive feature of major depression. We examined whether neonatal isolation (NI) could influence the incidence of learned helplessness (LH) in a rat model mimicking the pessimism, and the number of vesicular glutamate transporter 2 (VGLUT2)-expressing VP cells and Penk-expressing VP cells...

Just like an army of ants caught in an ant mill, individuals, groups and even whole societies are sometimes caught up in a Death Spiral, a vicious cycle of self-reinforcing dysfunctional behavior characterized by continuous flawed decision making, myopic single-minded focus on one (set of) solution(s), denial, distrust, micromanagement, dogmatic thinking and learned helplessness. We propose the term Death Spiral Effect to describe this difficult-to-break downward spiral of societal decline. Specifically, in the current theory-building review we aim to: (a) more clearly define and describe the Death Spiral Effect; (b) model the downward spiral of societal decline as well as an upward spiral; (c) describe how and why individuals, groups and even society at large might be caught up in a Death Spiral; and (d) offer a positive way forward in terms of evidence-based solutions to escape the Death Spiral Effect...

Fear overgeneralization is a maladaptive response to traumatic stress that is associated with the inability to discriminate between threat and safety contexts, a hallmark feature of post-traumatic stress disorder (PTSD). However, the neural mechanisms underlying this deficit remain unclear. Here, we show that traumatic stress exposure impairs contextual discrimination between threat and safety contexts in the learned helplessness (LH) model. Mossy cells (MCs) in the dorsal hippocampus are suppressed in response to traumatic stress...

AIMS AND METHOD: We aimed to explore experiences of workplace violence in a New Zealand sample of psychiatric trainees and to identify barriers to achieving safe practice and ways of enhancing workplace safety. In a qualitative study, we used interpretive description to inform and design in-depth exploration of participants' experiences. We interviewed 12 psychiatric trainees. Data were analysed using reflexive thematic analysis. RESULTS: There were three main themes: (a) violence as 'part of the job', leading to a culture of silence; (b) empowering trainees to address a sense of learned helplessness; and (c) conflict embedded within the unique nature of psychiatry...

PURPOSE: Learned helplessness (LH) is the psychological state in which an individual experiences multiple failures and setbacks and experiences a sense of loss when facing the current situation. It is a significant burden for lung cancer patients that can impair quality of life and lead to physical, social, and psychological difficulties. Thus, this study aimed to determine the level of LH among patients with lung cancer and identify factors associated with LH. PATIENTS AND METHODS: From August 2022 to March 2023, 237 patients with lung cancer from Chongqing University Cancer Hospital were selected for this study...

Osteoarthritis (OA) persistently activates nociceptors, leading to chronic pain, which is often accompanied by the comorbid development of emotional impairments (anxiety and depression), an effect associated with microgliosis. Baccharis dracunculifolia DC (Asteraceae), a Brazilian edible plant, is an important source of active compounds with anti-inflammatory abilities. Thus, we evaluated its ability to reverse OA-induced nociceptive and emotional-like impairments in osteoarthritic ovariectomized female rats using the kaolin/carrageenan (K/C) model...

INTRODUCTION: To explore the predictive effect of effort-reward imbalance on students' learning engagement and to elucidate the underlying mechanism, 796 students were selected for a survey. METHODS: The participants were required to complete four scales: the Effort-reward Imbalance Scale, the Learning Engagement Scale, the Learned Helplessness Questionnaire, and the Perceived Social Support Scale. RESULTS: (1) Students' effort-reward imbalance significantly and negatively predicts their learning engagement; (2) Learned helplessness serves as a mediator in the relationship between students' effort-reward imbalance and learning engagement; (3) Social support plays a moderating role in the association between effort-reward imbalance and learned helplessness...

BACKGROUND: The COVID-19 pandemic presents a significant challenge to professional responders in healthcare settings. This is reflected in the language used to describe the pandemic in the professional literature of the respective professions. The aim of this multidisciplinary study was to analyze the linguistic imagery in the relevant professional literature and to determine the identification of different professional groups with it and its emotional effects. METHOD: A list of 14 typical, widespread and differing imageries for COVID-19 in form of single sentences (e...

UNLABELLED: In our continuous effort to develop novel antiepileptic drug, a new series of nipecotic acid derivatives having1,3,4-thiadiazole nucleus were designed and synthesized. This study aims to improve the lipophilicity of nipecotic acid by attaching some lipophilic anchors like thiadiazole and substituted aryl acid derivatives. In our previous study, we noticed that the N-substituted oxadiazole derivative of nipecotic acid exhibited significant antiepileptic activity in the rodent model...

BACKGROUND: Acceptance of pain is one of the most significant topics in the field of chronic pain due to its influence on the adaptation and response of people. Also, chronic pain and pain caused by the progress of cancer have a high prevalence in all stages and types of cancer. AIMS: The present study aimed to predict the acceptance of chronic pain in patients with cancer based on anxiety sensitivity and emotional suppression with the mediating role of learned helplessness...

Chronic stress is deemed a significant clinical contributor to depression. The use of animal models of chronic stress can fully reveal the complex pathological mechanisms and their changing trends in the pathogenesis of depression, which is crucial for both disease prevention and therapy. It is also unknown how various forms of stress differ in their impact on animal physiology and behavior. The nucleus accumbens (NAc), an essential brain area for the pathophysiology of depression, and its underlying neural mechanisms remain unclear...

BACKGROUND: People living with dementia should be at the center of decision-making regarding their plans and goals for daily living and meaningful activities that help promote health and mental well-being. The human-computer interaction community has recently begun to recognize the need to design technologies where the person living with dementia is an active rather than a passive user of technology in the management of their care. METHODS: Data collection comprised semi-structured interviews and focus groups held with dyads of people with early-stage dementia (n = 5) and their informal carers (n = 4), as well as health professionals (n = 5)...

PURPOSE: This study investigates the impact of a Virtual Reality (VR)-based Mental Health Nursing Practice Simulation (MHNPS) on nursing students' competency in caring for individuals with mental disorders. Nursing students often face fear, anxiety, and helplessness during mental health (MH) rotations, impeding the attainment of learning objectives in the MH nursing practicum. Therefore, innovative strategies offering practice opportunities are crucial for their competence development...

A metasynthesis was performed on 15 qualitative studies to document the experience of revictimization by an intimate partner among women, based on survivors' perspectives on their sustained childhood sexual abuse and intimate partner violence victimization. Results identified two main conceptual categories: (a) Barriers to action: A belief system reflecting learned helplessness that hinders women's abilities to protect themselves and prevent further abuses, and (b) Broken internal compass: Cognitive elements blurring women's risk evaluation capacities and reference points limiting their ability to break the cycle of revictimization...

When Covid-19 was declared a pandemic, most people felt helpless, fearful, and demoralized while health care workers put their own lives at risk to support and heal others. The uncertainties expressed by experts and the ambiguous and protracted nature of the pandemic compounded the sense of frustration caused by the scarcity of protective equipment and effective medications. This combination of factors led to exhaustion, burnout, and moral injury. As a result, mental health practitioners worldwide realized that health care staff needed to stay motivated and resilient...

BACKGROUND: Although findings from both animal and clinical research indicate that the blood-brain barrier (BBB) contributes to the pathogenesis of various psychiatric disorders (including depression), the underlying mechanisms are unknown. We investigated the levels of the tight-junction proteins claudin-5 and aquaporin-4 (AQP-4) in astrocytes of learned helplessness (LH) rats (an animal model of depression) and non-LH rats (a model of resilience). METHODS: We administered inescapable mild electric shock to rats and then identified the LH and non-LH rats by a post-shock test...

INTRODUCTION: Many socially significant diseases are associated with prenatal developmental disorders. Previously, we showed the pathological role of hypoxia-inducible factor HIF1 in post-hypoxic reoxygenation. This study aimed to investigate the effect of prenatal severe hypoxia (PSH) on HIF1α protein expression as well as on HIF1-dependent activity of the pentose phosphate pathway (PPP) and anaerobic glycolysis in the hippocampus (HPC) of offspring that reached adulthood. METHODS: PSH was induced during the critical period of fetal hippocampal formation on gestation days 14-16 in a hypobaric chamber (180 Torr, 5% oxygen, 3 hours)...

Making arrangements by learning how intensive care patients feel due to a disease called as fatal worldwide can make it easier for patients to cope with the disease. For this reason, it is important for healthcare professionals to understand the patients who have been infected and discharged during the COVID-19 pandemic. The experiences of the patients may affect the perspective of the disease and cause different changes in the perception of it. This study, which was conducted based on this idea, aimed to examine the intensive care experiences of patients discharged from the COVID-19 intensive care unit...
