Background: Childhood trauma has negative immediate and long-term impacts on depression. Questions remain, however, regarding the cognitive factors influencing this relationship. This study aimed to investigate the role of three cognitive factors - cognitive overgeneralisation, rumination and social problem-solving - as mediating factors in the relationship between childhood trauma and symptoms of depression. Methods: We conducted a cross-sectional study in Iran from March to July 2023. Participants ( N  = 227; Mean age 32...

In the summer of 2023, ingestion of Astylus atromaculatus (pollen beetle) was linked to spontaneous fatal disease in grazing cattle and sheep in Argentina and Uruguay. While the disease was experimentally reproduced in sheep and guinea pigs in the 1970's, no experimental reproductions have been attempted in cattle, and controversy exists as to whether this insect is indeed noxious to cattle and at which dose. Here, we demonstrate that A. atromaculatus causes acute fatal disease in Hereford calves at single oral dosages of 2...

Body talk among adolescent females has been associated with negative outcomes, including depressed mood, disordered eating, and body dissatisfaction. Yet, little work has investigated the manifestation of body talk in actual conversations between adolescent females or explored pathways through which body talk is spread (e.g., co-rumination). The present study examined body talk among adolescent female dyads ( N = 23 dyads) ages 13 to 17 ( M age = 15.12) using an observational design. Reciprocally nominated dyads were recruited from a high school in the southeastern United States...

BACKGROUND: Previous studies have suggested that response-style strategies (rumination, problem-solving, and distraction) can be risk or protective factors for the development of abnormal eating behaviors/attitudes (AEB) during adolescence. However, due to limited empirical data regarding the prospective effects of these strategies on AEB, further research is needed to clarify their role in developing AEB in adolescence. METHODS: This study investigated the one-year lagged effects of response-style strategies on AEB in 24,883 fourth- to eighth-grade students in Japan between 2015 and 2019 using a cross-lagged panel model...

INTRODUCTION: Non-suicidal self-injury (NSSI) is a highly prevalent maladaptive behavior, often used to cope with intense negative affect. Rumination is an emotion regulation strategy that leads to fixation on and exacerbation of (typically) negative affective states. However, studies examining the relationship between rumination and NSSI have yielded mixed results, showing high degrees of heterogeneity. METHODS: The present study conducted meta-analyses (k = 50) of the association between overall rumination and NSSI, and independent meta-analyses for each of four subtypes of rumination (general, depressive, brooding, reflection rumination)...

Sub-acute ruminal acidosis (SARA) is characterized by chronic low ruminal pH, occurs for feedlot cattle fed high-concentrate diets. Forages slow digestion and reduce acid production. We aimed to assess how motivated finishing cattle are to access forage (Sudan grass hay, SG) via their willingness to interact with an electrified barrier. Reticulorumen pH was measured to relate the results with digestive health. Twenty-eight animals fed a high-concentrate ration ad-libitum had access to 4 L of one of two treatments (n=14/treatment) fed 1x/d behind a barrier: 1) SG, or 2) an additional offering of the normal ration (TMR)...

BACKGROUND: Both ruminative thought processes and adverse childhood experiences (ACEs) are well-established risk factors for the emergence and maintenance of depression. However, the neurobiological mechanisms underlying these associations remain poorly understood. METHODS: We examined resting-state functional magnetic resonance imaging data (3 T Tim Trio MR scanner; Siemens, Erlangen) of 44 individuals diagnosed with an acute depressive episode. Specifically, we focused on investigating functional brain activity and connectivity within and between three large-scale neural networks associated with processes affected in depression: the default mode network (DMN), the salience network (SN), and the central executive network (CEN)...

BACKGROUND: Major Depressive Disorder (MDD) is one of the most prevalent psychiatric disorders, and involves high relapse rates in which persistent negative thinking and rumination (i.e., perseverative cognition [PC]) play an important role. Positive fantasizing and mindfulness are common evidence-based psychological interventions that have been shown to effectively reduce PC and subsequent depressive relapse. How the interventions cause changes in PC over time, is unknown, but likely differ between the two...

PURPOSE: The prevalence rate of non-suicidal self-injury (NSSI) in the clinical population is higher than that in the community sample, necessitating the need to investigate the predicting factors of NSSI in this group. The present study aimed to develop a prediction model of NSSI among psychiatric patients in Korea. MATERIALS AND METHODS: Decision tree analysis was conducted on a sample of 224 psychiatric patients. Emotion regulation strategies (rumination, cognitive reappraisal, and expressive suppression), impulsivity, problematic alcohol use, working memory, depressive mood, and gender were included in the model as predictors of NSSI...

Repetitive negative thinking (RNT) is a transdiagnostic symptom observed across mood and anxiety disorders and is characterized by frequent, distressing thoughts that are perceived as uncontrollable. Specific forms of RNT have been linked to increased suicide risk. However, most work examining links between RNT and suicide has been conducted within specific disorders and subtypes of RNT (e.g., rumination in individuals with depression). The present study aimed to investigate associations between transdiagnostic RNT and suicidal ideation...

INTRODUCTION: Rumination, defined as intrusive and repetitive thoughts in response to negative emotions, uncertainty, and inconsistency between goal and current situation, is a significant risk factor for depressive disorders. The rumination literature presents diverse findings on functional connectivity and shows heterogeneity in research methods. This systematic review seeks to integrate these findings and provide readers diverse perspectives. METHOD: For this purpose, the literature on functional connectivity in rumination was reviewed according to the PRISMA guidelines...

Anhedonia is a core aspect of major depressive disorder. Traditionally viewed as a blunted emotional state in which individuals are unable to experience joy, anhedonia also diminishes the drive to seek rewards and the ability to value and learn about them 1-4.The neural underpinnings of anhedonia and how this emotional state drives related behavioral changes remain unclear. Here, we investigated these questions by taking advantage of the fact that when mice are exposed to traumatic social stress, susceptible animals become socially withdrawn and anhedonic, where they cease to seek high-value rewards, while others remain resilient...

OBJECTIVE/BACKGROUND: Experimental studies suggest that sleep loss affects psychological outcomes. However, most studies focus on acute severe in-laboratory sleep restriction, with limited ecological validity. This study examines the impact of sustained mild sleep restriction (SR) on stress and distress among healthy adults in a naturalistic home environment. PATIENTS/METHODS: We analyzed data from two randomized crossover studies. Individuals who regularly slept 7-9 h/night completed two 6-wk intervention phases separated by a 6-wk washout: habitual sleep (HS: maintenance of habitual bed and wake times) and SR (delayed bedtime by 1...

Decreased levels of positive affect (PA) are a hallmark of depression. Current models propose as potential main mechanisms a dysfunctional use of emotion regulation (ER) strategies (i.e. dampening, positive rumination), and a maladaptive activation of pro-hedonic goals. However, the role of these mechanisms in PA in daily life remains understudied. We used a 10-day ESM design to assess how these mechanisms influence each other and contribute to depressive symptomatology-related low momentary PA in 139 individuals...
