Acute Psychosocial Stress

BackgroundExposure to stress and trait impulsivity are independent predictors of relapse in recovering alcoholics, but potential mechanisms that link these two risk-factors in terms of their putative additive or interactive contributions to relapse are not known. The aim of this study was to use a model of stress-induced relapse to test the hypothesis that acute psychosocial stress increases craving for alcohol in social drinkers. We also tested the hypothesis that change in craving could be explained by variability in impulsivity and risk-taking.MethodsParticipants completed questionnaires to assess drinking behaviour (Alcohol Dependence Questionnaire [ADQ]; and an Alcohol Use Disorders Identification Test [AUDIT]), craving (Desires for Alcohol Questionnaire [DAQ] and impulsivity (Barrett Impulsiveness Scale [BIS]). Participants also completed two computer tasks to assess risk-taking and impulsivity, the Balloon Analogue Risk Test (BART) and a continuous performance task (CPT). Participants then underwent the Trier Social Stress Test (TSST), and completed a final DAQ to assess post-stress craving.ResultsParticipants showed an increase in craving following exposure to the TSST. In addition, risk-taking was positively correlated with change in craving.ConclusionsOur data suggests that acute psychosocial stress increases subjective craving in social drinkers, but that the effects may be trait-dependent, with stress-induced increases in craving correlated with risk-taking.

Acute Psychosocial Stress

Abstract Context The renin-angiotensin-aldosterone system (RAAS) plays an important role in cardiovascular homeostasis and its dysfunction relates to negative health consequences. Acute psychosocial stress seems to activate the RAAS in humans, but stress kinetics and interrelations of RAAS parameters compared with a nonstress control group remain inconclusive. Objective We systematically investigated in a randomized placebo-controlled design stress kinetics and interrelations of the reactivity of RAAS parameters measured in plasma and saliva to standardized acute psychosocial stress induction. Methods 58 healthy young men were assigned to either a stress or a placebo control group. The stress group underwent the Trier Social Stress Test (TSST), while the control group underwent the placebo TSST. We repeatedly assessed plasma renin, and plasma and salivary aldosterone before and up to 3 hours after stress/placebo. We simultaneously assessed salivary cortisol to validate successful stress induction and to test for interrelations. Results Acute psychosocial stress induced significant increases in all endocrine measures compared with placebo-stress (all P ≤ .041). Highest renin levels were observed 1 minute after stress, and highest aldosterone and cortisol levels 10 and 20 minutes after stress, with salivary aldosterone starting earlier at 1 minute after stress. Renin completed recovery at 10 minutes, cortisol at 60 minutes, salivary aldosterone at 90 minutes, and plasma aldosterone at 180 minutes after stress. Stress increase scores of all endocrine measures related to each other, as did renin and cortisol areas under the curve with respect to increase (AUCi) and salivary and plasma aldosterone AUCi (all P ≤ .047). Conclusions Our findings suggest that in humans acute psychosocial stress induces a differential and interrelated RAAS parameter activation pattern. Potential implications for stress-related cardiovascular risk remain to be elucidated.

Cognitive reappraisal (CR) is regarded as an effective emotion regulation strategy. Acute stress, however, is believed to impair the functioning of prefrontal-based neural systems, which could result in lessened effectiveness of CR under stress. This study tested the behavioral and neurobiological impact of acute stress on CR. While undergoing fMRI, adult participants ( n = 54) passively viewed or used CR to regulate their response to negative and neutral pictures and provided ratings of their negative affect in response to each picture. Half of the participants experienced an fMRI-adapted acute psychosocial stress manipulation similar to the Trier Social Stress Test, and a control group received parallel manipulations without the stressful components. Relative to the control group, the stress group exhibited heightened stress as indexed by self-report, heart rate, and salivary cortisol throughout the scan. Contrary to our hypothesis, we found that reappraisal success was equivalent in the control and stress groups, as was electrodermal response to the pictures. Heart rate deceleration, a physiological response typically evoked by aversive pictures, was blunted in response to negative pictures and heightened in response to neutral pictures in the stress group. In the brain, we found weak evidence of stress-induced increases of reappraisal-related activity in parts of the PFC and left amygdala, but these relationships were statistically fragile. Together, these findings suggest that both the self-reported and neural effects of CR may be robust to at least moderate levels of stress, informing theoretical models of stress effects on cognition and emotion.

Psychostimulant drugs alter the salience of stimuli in both laboratory animals and humans. In animals, stimulants increase rates of responding to conditioned incentive stimuli, and in humans, amphetamine increases positive ratings of emotional images. However, the effects of stimulants on real-life emotional events have not been studied in humans. In this study, we examined the effect of d-amphetamine on responses to acute psychosocial stress using a public speaking task. Healthy volunteers ( N=56) participated in two experimental sessions, one with a psychosocial stressor (the Trier Social Stress Test) and one with a non-stressful control task. They were randomly assigned to receive d-amphetamine (5 mg n=18, 10 mg n=20) or placebo ( n=18) on both sessions under double blind conditions. Salivary cortisol, subjective mood, and vital signs were measured at regular intervals during the session. Subjects also provided cognitive appraisals of the tasks before and after their performances. Amphetamine produced its expected mood and physiological effects, and the Trier Social Stress Test produced its expected effects on cortisol and mood. Although neither dose of amphetamine altered cardiovascular or hormonal responses to stress, amphetamine (10 mg) increased participants’ pre-task appraisals of how challenging the task would be, and it increased post-task ratings of self-efficacy. Paradoxically, it also increased ratings of how stressful the task was, and prolonged aversive emotional responses. These findings suggest that amphetamine differentially affects stress response components: it may increase participants’ appraisals of self-efficacy without dampening the direct emotional or physiological responses to the stress.

IntroductionResponse inhibition (RI) is a basic component of human behaviour responsible for suppressing actions or thoughts which are inappropriate in a certain context. This cognitive function is well-studied in laboratory conditions, but there is limited data how it is influenced by emotional context and psychosocial stress.ObjectivesThe effect of emotional factors on RI can be investigated with an emotional go/nogo task, while psychosocial stress can be induced with the Trier Social Stress Test (TSST). Electroencephalography (EEG) is an excellent method for studying the neural correlates of RI: the two major event-related potentials (ERPs) implicated in the process are the frontal N2 and P3 components.AimsIn this respect, our aim was to investigate how psychosocial stress and emotional context modulate these ERPs.MethodsSeven healthy adult volunteers performed emotional go/no go tasks while brain responses were recorded by EEG. The task was carried out on two different occasions: at baseline condition and after moderate psychosocial stress induced by the TSST.ResultsWe successfully replicated the robust go vs. nogo effect on the frontal N2 and P3 amplitudes. However, ERPs were not affected by positive or negative emotional context in the baseline condition. In contrast, after TSST a significantly enhanced valence effect was observed on the go-related N2 amplitude and a greater go vs. nogo N2 latency difference was detected.ConclusionsThese findings highlight the importance of the stress-regulating system on emotionally modulated RI and render this paradigm a promising tool for investigating RI in anxiety and mood disorders.

Abstract. Psychosocial stress has been shown to alter social perception and behavior. In the present study, we investigated whether a standardized psychosocial stressor modulates the perceptual sensitivity for positive and negative facial emotions and the tendency to allocate attention to facial expressions. Fifty-four male participants underwent the Trier Social Stress Test for Groups (TSST-G) or a nonstressful control condition before they performed a facial emotions detection task and a facial dot-probe task to assess attention for positive and negative facial expressions. Saliva samples were collected over the course of the experiment to measure free cortisol and alpha amylase. In response to the TSST-G, participants showed marked increases in subjective stress, salivary cortisol, and alpha amylase compared to the control condition. In the control condition, detection performance was higher for angry compared to happy facial expressions, while in the stressful condition this difference was reversed. Here, participants were more sensitive to happy compared to angry facial expressions. Attention was unaffected by psychosocial stress. The results suggest that psychosocial stress shifts social perception in terms of detection sensitivity for facial expressions toward positive social cues, a pattern that is consistent with the tendency to seek social support for coping with stress.

Perforin ( PRF1) is essential for immune surveillance and studies report decreased perforin in chronic fatigue syndrome (CFS), an illness potentially associated with stress and/or infection. We hypothesize that stress can influence regulation of PRF1 expression, and that this regulation will differ between CFS and non-fatigued (NF) controls. We used the Trier Social Stress Test (TSST) as a standardized acute psychosocial stress, and evaluated its effect on PRF1 expression and methylation in CFS (n = 34) compared with NF (n = 47) participants. During the TSST, natural killer (NK) cells increased significantly in both CFS ( P = <0.0001) and NF subjects ( P = <0.0001). Unlike previous reports, there was no significant difference in PRF1 expression at baseline or during TSST between CFS and NF. However, whole blood PRF1 expression increased 1.6 fold during the TSST in both CFS ( P = 0.0003) and NF ( P = <0.0001). Further, the peak response immediately following the TSST was lower in CFS compared with NF ( P = 0.04). In addition, at 1.5 hours post TSST, PRF1 expression was elevated in CFS compared with NF (whole blood, P = 0.06; PBMC, P = 0.02). Methylation of seven CpG sites in the methylation sensitive region of the PRF1 promoter ranged from 38%-79% with no significant differences between CFS and NF. Although, the average baseline methylation of all seven CpG sites did not differ between CFS and NF groups, it showed a significant negative correlation with PRF1 expression at all TSST time points in both CFS (r = –0.56, P = <0.0001) and NF (r = –0.38, P = <0.0001). Among participants with high average methylation (≥65%), PRF1 expression was significantly lower in CFS than NF subjects immediately following TSST. These findings suggest methylation could be an important epigenetic determinant of inter-individual differences in PRF1 expression and that the differences in PRF1 expression and methylation between CFS and NF in the acute stress response require further investigation.

Acute Psychosocial Stress

Dynamically adjusting the right amount of goal shielding to varying situational demands is associated with the flexibility of cognitive control, typically linked with pFC functioning. Although stress hormones are found to also bind to prefrontal receptors, the link between stress and cognitive control remains elusive. Based on that, we aimed at investigating effects of acute psychosocial stress on dynamic control adjustments. Forty-eight healthy volunteers were exposed to either a well-established stress induction protocol (the Trier Social Stress Test, TSST) or a standardized control situation before a selective attention (Simon) task involving response conflicts. The individual physiological stress response was monitored by analyzing levels of free cortisol and α-amylase activity in saliva samples showing that the TSST reliably induced an increase of endogenous stress hormone levels. Acute stress did not inevitably impair cognitive functioning, however, as stressed participants showed tonically increased goal shielding (to reduce interference) at the expense of decreased cognitive flexibility. Importantly, as a novel finding in humans, stress effects on cognitive functions were not present immediately after the stress experience but developed gradually over time and, therefore, paralleled the time course of the hypothalamus–pituitary–adrenal (HPA) stress response. In addition, the total increase of individual cortisol levels reflecting HPA activity, but not the total changes in α-amylase activity associated with sympathetic activity, was reversely related to the amount of cognitive flexibility in the final block of testing. Our study provides evidence for a stress-induced time-dependent decrease of cognitive flexibility that might be related to changes in cortisol levels.

BackgroundThe serotonin transporter gene-linked polymorphic region (5-HTTLPR) has previously been associated with hypothalamus–pituitary–adrenal axis function. Moreover, it has been suggested that this association is moderated by an interaction with stressful life experiences.AimsTo investigate the moderation of cortisol response to psychosocial stress by 5-HTTLPR genotype, either directly or through an interaction with early life stress.MethodA total of 151 women, 85 of which had personality psychopathology, performed the Trier Social Stress Test while cortisol responsivity was assessed.ResultsThe results demonstrate a main effect of genotype on cortisol responsivity. Women carrying two copies of the long version of 5-HTTLPR exhibited stronger cortisol responses to psychosocial stress than women with at least one copy of the short allele (P = 0.03). However, the proportion of the variance of stress-induced cortisol responsivity explained by 5-HTTLPR genotype was not further strengthened by including early life adversity as a moderating factor (P = 0.52).ConclusionsOur results highlight the need to clarify gender-specific biological factors influencing the serotonergic system. Furthermore, our results suggest that childhood maltreatment, specifically during the first 15 years of life, is unlikely to exert a moderating influence of large effect on the relationship between the 5-HTTLPR genotype and cortisol responsivity to psychosocial stress.Declaration of interestNone.

Abstract. Tasks such as the Trier Social Stress Test, narrative recall, and some cognitive challenges require participants to speak in order to measure acute physiological responses to induced stress. Typically, the physiological measures during the stressed state are compared to a silent baseline period. This does not differentiate between stress that is induced by emotion and stress due to the physical act of vocalization. We modified a psychosocial stress task for 41 participants to add a period of neutral speaking. We hypothesized that there would be significant differences in physiological measures between the silent baseline and neutral speaking periods, and that these differences would explain a substantial proportion of the stress response traditionally attributed to emotion. Blood pressure, skin conductance level, respiration rate, salivary alpha-amylase, and high frequency heart rate variability showed significant changes during the neutral speaking period compared to a silent baseline, demonstrating the need for this control. Of the magnitude of physiological response which would have typically been attributed to emotion, 36–77% was due to vocalization alone. In stress-inducing tasks that require speaking, care should be taken in study design to account for the physiological impact of speech.
