Stress Reactivity and Cognitive Vulnerability for Depression in Adolescence
… supported risk factors for depression: stress reactivity and cognitive vulnerabilities (CV). To varying degrees, these factors have been examined throughout development; yet, these bodies of literature have been surprisingly separate, which may contribute to the disappointing performance …

Stress reactivity, stress appraisal and coping responses in schizophrenia
… the etiology of schizophrenia. According to the stress-vulnerability model, the experience of stress is critical to the onset and/or maintenance of schizophrenia. Although there is no conclusive evidence to suggest that people with schizophrenia experience more stressful events than the general …

The Effect Of Abstinence From Smoking On Stress Reactivity
Subjective stress is a well-documented predictor of early smoking relapse, yet our understanding of stress and tobacco use is limited by the reliability of current available measures of stress. Functional magnetic reasoning imaging (fMRI) could provide a much-needed objective measure of stress …

Personality resources and stress reactivity : potential mechanisms in stress-related psychopathology
… "adaptiveness" of the individual is reflected in stress-related patterns of mood change, cardiac activity, and selective attention. Cognitive adaptiveness to stress was defined by a profile of five personality traits: locus of control, self-efficacy, self-esteem, optimism, and anxiety. The sample …

Early Adversity and Cardiovascular Stress Response: Stress Reactivity Or Biological Sensitivity to Context
The stress reactivity hypothesis (SRH) posits highly stressful early environments contribute to exaggerated cardiovascular (CV) reactivity and/or slower CV recovery, which in turn contributes to CV disease. These associations are well-supported in the literature; however, a growing number of …

Individual differences in stress reactivity: implications for adolescent athletes’ performance and well-being.
… by adolescent athletes, in what is a highly stressful period of their development. Stress reactivity is a stable individual difference underlying the broad variability in responses to stress, which has received very little attention within sporting contexts. Therefore, this PhD aims to …

Stress Reactivity Patterns in Breast Cancer Survivors and the Implications of Various Psychosocial Factors
The stress system comprises the hypothalamic-pituitary-adrenal (HPA) and the sympathetic-adrenal-medullary (SAM) axes. The two operate synergistically to regulate metabolic and biological processes, maintain homeostasis, and manage physiological responses towards various environmental challenges, …

Translational Regulation in Excitatory Neurons Controls Stress Reactivity and the Antidepressant Response to Ketamine
… one-third remaining treatment-resistant. Chronic stress is a major risk factor for MDD, whereas acute stress is adaptive and mediated by hypothalamic-pituitary-adrenal axis activation. Ketamine produces rapid antidepressant effects, partly through mammalian target of rapamycin complex 1 (mTORC1) …

An Exploration of Stress Reactivity and Mindfulness Meditation in Individuals with Migraine Utilizing Heart Rate Variability
… in those with headache disorders after cognitive stress induction. These studies have found there were significant increases in HRV after stress induction in those that practiced MM. The current study examined HRV changes in migraineurs. Participants (N=26) were randomly assigned to a 10-minute …

Mitigating Risk for Anxiety Among Preschool-Age Children Living in Poverty: Evaluating the Impact of Adult-Provided Social Support on Autonomic Stress Reactivity
<p>Poverty increases children's exposure to stress, elevating their risk for developing patterns of heightened sympathetic and parasympathetic stress reactivity. Repeated patterns of high sympathetic activation and parasympathetic withdrawal place children at risk for anxiety disorders. This study …

The Moderating Role of Mindfulness on the Relationship between Parental Stress and Response to Child
Increased stress levels due to parenting have been shown to correlate to harsher parenting responses towards children (Belsky, 1984). Mindfulness, however, suggests the ability to focus on the present moment in a nonjudgmental and nonreactive manner. Similarly, parents with increased mindfulness …

Neurofunctional Characterization of the At-Risk Mental State for Psychosis
… glutamatergic dysfunction, and dysfunctional stress-reactivity. Prior to the onset of schizophrenia there is a prodromal period when individuals begin to experience sub-clinical symptoms and decreased functioning. This period is important to study not only to help elucidate biologic mechanisms …

Differentiation between the Effects of Physical and Psychosocial Stress on a Feedback-based Learning Task
… This learning process is influenced by acute stress. However, different laboratory stressors elicit different physiological response patterns, which may influence feedback processing differently. Moreover, individual differences in stress reactivity may be associated with reward sensitivity. …
