#1
Christopher C Sova, John E Roberts
BACKGROUND AND OBJECTIVES: The cognitive catalyst model posits that rumination and negative cognitive content, such as negative schema, interact to predict depressive affect. Past research has found support for this model using explicit measures of negative cognitive content such as self-report measures of trait self-esteem and dysfunctional attitudes. The present study tested whether these findings would extend to implicit measures of negative cognitive content such as implicit self-esteem, and whether effects would depend on initial mood state and history of depression...

Paola Lucena-Santos, José Pinto-Gouveia, Sérgio A Carvalho, Margareth da Silva Oliveira
OBJECTIVES: Although the Ruminative Responses Scale is one of the most widely used measures of rumination, its two-factor structure remains controversial. Taking this into account, we aimed to test the RRS-10 two-factor invariance (Brazilian version) between different samples of women and to study its internal consistency and convergent validity. METHODS: A sample of 321 women (general population, n = 106; college students, n = 115; and medical population of patients with overweight and obesity, n = 100) participated in the study...

Michael Proeve, Rebekah Anton, Maura Kenny
OBJECTIVES: The tendency to experience shame or guilt is associated differentially with anxiety and depression, with shame being associated with greater psychopathology. Correlational studies have shown self-compassion to be related to lower shame and rumination, and mindfulness-based interventions increase self-compassion. Therefore, mindfulness-based interventions may decrease shame. This pilot study aimed to assess the association of shame, rumination, self-compassion, and psychological distress and the effects of a mindfulness-based intervention on these measures in a clinical sample...

Serotonin 1A (5-HT1A ) receptors play a direct role in neuronal development, cell proliferation, and dendritic branching. We hypothesized that variability in 5-HT1A binding can affect cortical thickness, and may account for a subtype of major depressive disorder (MDD) in which both are altered. To evaluate this, we measured cortical thickness from structural magnetic resonance imaging (MRI) and 5-HT1A binding by positron emission tomography (PET) in an exploratory study. To examine a range of 5-HT1A binding and cortical thickness values, we recruited 25 healthy controls and 19 patients with MDD...

OBJECTIVE: Chronic embitterment has received considerable attention in terms of its presentation and epidemiology, but there has been relatively little focus on its psychology. The present study aimed to test the hypothesis that embitterment is positively correlated with rumination, and that this effect is influenced by positive beliefs about rumination. METHOD: A convenience sample (N = 79) of staff of a health care facility attending its occupational health service completed questionnaires assessing chronic embitterment, work-related rumination (distinguishing affective rumination and problem solving pondering), positive beliefs about rumination, and depression...

Corticotropin-releasing factor signaling through CRF receptor type 1 (CRF1) has been shown to contribute to learning and memory function. A haplotype of alleles T-A-T in a set of common polymorphisms in the gene encoding for CRF1 (CRHR1) has been associated with both depression vulnerability and alterations in cognitive functioning. The present study investigated the relations between the TAT haplotype and specific symptoms of depression, self-reported ruminative behaviors, and neuropsychological performance on a learning and memory task...

BACKGROUND: Even though there is an increasing number of studies on the efficacy of Internet-based interventions (IBI) for depression, experimental trials on the benefits of added guidance by clinicians are scarce and inconsistent. This study compared the efficacy of semistandardized feedback provided by psychologists with fully standardized feedback in IBI. METHODS: Participants with mild-to-moderate depression (n = 1,089, 66% female) from the client pool of a health insurance company participated in a cognitive-behavioral IBI targeting depression over 6 weeks...

Suicide-specific rumination, defined as a mental fixation on one's suicidal thoughts, intentions, and plans, may be an important predictor of suicidal behavior. To date, suicide-specific rumination has demonstrated convergence with, yet distinction from, a variety of suicide risk factors, and differentiated suicide attempters from ideators. However, no research has examined whether suicide-specific rumination is associated with lifetime suicide attempts above and beyond the presence of a host of other relevant suicide risk factors...

OBJECTIVES: The objective was to assess the impact of cognitive factors on post-partum depression (PPD) symptoms. Because most of the literature data concern the immediate post-partum period or the first year post-partum, we notably sought to assess the longer term impact of cognitive factors on the symptoms of PPD. METHODS: Two studies were performed. In a pilot study, 1-month post-partum, 63 women filled out a sociodemographic information sheet and completed the abbreviated, revised Eysenck Personality Questionnaire, the Ruminative Responses Scale, the Maternal Self-Report Inventory, and the Edinburgh Post-Natal Depression Scale...

AIM: Multiple sclerosis (MS) is a chronic demyelinating disease that poses significant life challenges. Depression and anxiety often occur in people with MS (PwMS). An information processing model of psychopathology, the Self-Regulatory Executive Function (S-REF) model specifies that maladaptive metacognitive beliefs play a fundamental role in the development and maintenance of distress. The model also asserts that a style of thinking known as the cognitive attentional syndrome (CAS), which consists of worry and rumination, focusing on sources of threat, and unhelpful coping responses, is common across all psychological conditions...

This study aimed to examine the temporal (hourly within a day and daily over the long term) effects of monensin on CH4 emissions, ruminal fermentation, and in situ alfalfa degradation in dairy goats during dietary monensin supplementation by controlling the confounding effects of feed intake and ambient temperature. Six ruminally cannulated dairy goats were used, and they were housed in environmental chambers and fed a restricted amount of ration throughout the experiment. The experiment included a baseline period of 20 d followed by a treatment period of 55 d with 32 mg of monensin/d...

In major depressive disorder (MDD), the anterior cingulate cortex (ACC) has been associated with clinical outcome as well as with antidepressant treatment response. Nonetheless, the association between individual differences in ACC structure and function and the response to cognitive behavioral therapy (CBT) is still unexplored. For this aim, twenty-five unmedicated patients with MDD were scanned with structural and resting state functional magnetic resonance imaging before the beginning of CBT treatment. ACC morphometry was correlated with clinical changes following psychotherapy...

Feeding trials were conducted with lactating cows and growing lambs to quantify effects of replacing dietary alfalfa silage (AS) with red clover silage (RCS) on nutrient utilization. The lactation trial had a 2 × 4 arrangement of treatments: AS or RCS fed with no supplement, rumen-protected Met (RPM), rumen-protected Lys (RPL), or RPM plus RPL. Grass silage was fed at 13% of dry matter (DM) with AS to equalize dietary neutral detergent fiber (NDF) and crude protein contents. All diets contained (DM basis) 5% corn silage and 16% crude protein...

The Ruminative Thought Scale (RTS) was developed to measure the ruminative thinking style, presumably common to various psychopathological disorders. However, prior factor-analytic research was inconclusive regarding unidimensionality versus multidimensionality of the RTS. The present study was conducted on a large, heterogeneous Serbian sample ( N = 838). A subsample was retested 6 months later providing information about symptoms of depression and various anxiety symptoms. Results showed that a bifactor model of the RTS (representing one general and four group factors) had a better fit than the second-order and one-factor models...

OBJECTIVE: Mild traumatic brain injuries (mTBIs) have frequently been associated with the emergence and persistence of depressive symptoms. However, the factors which contribute to the increased risk for depression after these head injuries remain unclear. Accordingly, we examined the relationship between frequency of self-reported mTBIs and current symptoms of depression and the mediating role of rumination and cognitive flexibility. We also examined whether these relations were moderated by sex differences and the presence of the Val66Met polymorphism in a gene coding for brain-derived neurotrophic factor (BDNF)...

Our objective was to determine the effects of dry matter intake (DMI), body weight (BW), and diet characteristics on total tract digestibilities of dry matter, neutral detergent fiber, and starch (DMD, NDFD, and StarchD, respectively) in high-producing dairy cows. Our database was composed of 1,942 observations from 662 cows in 54 studies from Michigan, Ohio, and Georgia. On average, cows ate 23 ± 4.5 kg of dry matter/d, weighed 669 ± 79 kg, and produced 38 ± 10 kg of milk/d. Diets were 31 ± 5% neutral detergent fiber, 27 ± 6% starch, 2...

The objective of this study was to apply digital imaging to improve quantification of rumen protozoal biomass and distinguish treatment differences in cell motility and volume among ruminal protozoa. Observations of protozoa in rumen fluid treated with essential oils (CinnaGar, CIN; Provimi North America, Brookville, OH) or an ionophore (monensin, MON) indicated possible cell shrinkage. We hypothesized that MON would decrease protozoal motility and interact with CIN on cell volume. In addition, we hypothesized that analysis of still frames from video of swimming protozoa would improve volume prediction accuracy...
