Autonomic arousal in anxious and typically developing youth during a stressor involving error feedback

Resting State Psychophysiology in Youth with OCD and Their Caregivers: Preliminary Evidence for Trend Synchrony and Links to Family Functioning

The burden of OCD in children and adolescents extends to their caregivers. Prior work in other disorders and unaffected youth has found synchrony in psychophysiological arousal for youth-caregiver dyads. This preliminary study explored whether psychophysiological trend synchrony in youth-caregiver dyads (N = 48) occurred and was moderated by youth OCD diagnosis. We also explored whether psychophysiological indices (i.e., electrodermal activity, heart rate, respiratory sinus arrhythmia) were correlated with reported family functioning in the OCD subsample (n = 25). Youth with OCD had higher resting heart rate than unaffected peers; this was not replicated in caregivers. Trend synchrony was found across the full sample of dyads for electrodermal activity and heart rate, with no moderation by diagnostic group. In the OCD group, youth heart rate was correlated with family conflict and caregiver heart rate with expressiveness. Findings provide preliminary support for further examination of heart rate and family factors in OCD-affected youth and their caregivers.

Heart rate variability and psychological health: The key role of trait emotional awareness

Studies have shown that Trait Emotional Awareness (TEA) - the ability to recognize one's emotions - and Heart Rate Variability (HRV) are both negatively associated with psychological disorders. Although these studies imply that TEA is related to HRV and may explain the association between HRV and psychological disorders, there is limited research investigating this implication. Such investigation is essential to illuminate the psychophysiological processes linked to psychological disorders. The present study aims to investigate a) the association between TEA and HRV, b) the association between HRV and psychological disorders, and c) whether TEA explains the association between HRV and psychological disorders. A sample of 41 German students completed self-report questionnaires as indicators of psychological disorders, including the Hospital Anxiety and Depression Scale (HADS; Snaith & Zigmond, 1983) for anxiousness and depressiveness, as well as the somatization scale of the Hopkins Symptom Checklist (HSCL; Derogatis et al., 1976) for physical complaints. HRV was measured at baseline (resting HRV) and during exposure to a fear-provoking movie clip (reactive HRV). As hypothesized, a) TEA showed a positive association with reactive HRV, b) HRV showed negative associations with anxiousness and physical complaints, and c) TEA explained the relationships between reactive HRV and anxiousness, as well as physical complaints. Contrary to our hypothesis, we did not find any association between HRV and depressiveness. We discussed the contribution of TEA to psychophysiological health, limited generalizability of the current study, and direct future research to explore the underlying mechanisms linking TEA to health.

Multidimensional components of (state) mathematics anxiety: Behavioral, cognitive, emotional, and psychophysiological consequences

The present study aimed to analyze the different components of state mathematics anxiety that students experienced while solving calculation problems by manipulating their stress levels. A computerized mathematical task was administered to 165 fifth-graders randomly assigned to three different groups: positive, negative, and control conditions, in which positive, negative, or no feedback during the task was given, respectively. Behavioral (task performance), emotional (negative feelings), cognitive (worrisome thoughts and perceived competence), and psychophysiological responses (skin conductance and vagal withdrawal) were analyzed. Behavioral responses did not differ in the positive and negative conditions, while the latter was associated with children's reportedly negative emotional states, worries, and perceived lack of competence. The stress induced in the negative condition led to an increase in skin conductance and cardiac vagal withdrawal in children. Our data suggest the importance of considering students' interpretation of mathematics-related experiences, which might affect their emotional, cognitive, and psychophysiological responses.

Autonomic Dysregulation in Child Social Anxiety Disorder: An Experimental Design Using CBT Treatment

Models of social anxiety disorder (SAD) stress the relevance of physiological arousal. So far, limited research has been conducted in children with SAD in experimental stress designs. Thus, examining autonomic arousal, children with and without SAD completed a standardized social stressor (Trier Social Stress Test for Children-C; TSST-C). Pre-existing differences to healthy controls (HC) were expected to decrease after receiving cognitive behavior therapy (CBT). Children with SAD (n = 64) and HC children (n = 55) completed a TSST-C. Children with SAD participated in a second TSST-C after either cognitive-behavioral treatment or a waitlist-control period (WLC). As expected, children with SAD showed blunted heart rate reactivity compared to HC children. Further, children with SAD had elevated levels of tonic sympathetic arousal as indexed by skin conductance level compared to HC. Children with SAD showed lower parasympathetic arousal during the baseline compared to HC. Children receiving treatment did not differ from children in the WLC condition in a repeated social stress test. Psychophysiological differences between children with SAD and HC children could be confirmed as indicated by previous research. The lack of physiological effects of the intervention as an experimental manipulation might be related to slower changes in physiology compared to e.g. cognition.

Cardiovascular reactivity as a measure of irritability in a transdiagnostic sample of youth: Preliminary associations

OBJECTIVES

Irritability is a transdiagnostic symptom in developmental psychopathology, conceptualized as a low threshold for frustration and increased proneness to anger. While central to emotion regulation, there is a vital need for empirical studies to explore the relationship between irritability and underlying physiological mechanisms of cardiovascular arousal.

METHODS

We examined the relationship between irritability and cardiovascular arousal (i.e., heart rate [HR] and heart rate variability [HRV]) in a transdiagnostic sample of 51 youth (M = 12.63 years, SD = 2.25; 62.7% male). Data was collected using the Empatica E4 during a laboratory stop-signal task. In addition, the impact of motion activity, age, medication, and sleep on cardiovascular responses was explored.

RESULTS

Main findings showed that irritability was associated with increased HR and decreased HRV during task performance.

CONCLUSIONS

Findings support the role of peripheral physiological dysregulation in youth with emotion regulation problems and suggest the potential use of available wearable consumer electronics as an objective measure of irritability and physiological arousal in a transdiagnostic sample of youth.

Psychophysiological assessment of stress reactivity and recovery in anxiety disorders

The present study aimed to examine changes in psychophysiological arousal from baseline to a stressor phase (reactivity) and from the stressor phase to a second resting phase (recovery) in patients with anxiety disorders. Fifty adult patients with DSM-5 anxiety disorders (panic disorder, generalized anxiety disorder, or social anxiety disorder) and 28 healthy control (HC) participants underwent psychophysiological monitoring including electrocardiogram, respiration rate, electrodermal activity, gastrocnemius electromyograph, and end-tidal CO₂ for a 3-min resting phase, a 6-min mild stressor phase, and a 3-min recovery phase. Anxious patients then went on to receive naturalistic cognitive-behavioral therapy (CBT) in a specialty outpatient clinic. Results for the reactivity phase indicated that compared to HCs, patients with social anxiety disorder exhibited heightened psychophysiological reactivity while patients with panic disorder and generalized anxiety disorder exhibited attenuated reactivity. Results for physiological recovery (return to baseline after the stressor was withdrawn) were mixed, but provided some support for slower autonomic recovery in patients with generalized anxiety disorder and panic disorder compared to HCs. Participants with all anxiety disorders exhibited diminished change in high frequency heart rate variability compared to HCs. Generally, psychophysiological reactivity and recovery were not associated with CBT outcome, though exploratory analyses indicated that greater respiration rate reactivity and stronger respiration rate recovery were associated with better CBT outcomes in patients with panic disorder.

Anxiety and verbal learning in typically developing primary school children: Less efficient but equally effective

BACKGROUND

Despite evidence that high levels of anxiety can impair Working Memory (WM) functioning, little is known about how anxiety is associated with classroom learning activities, which make high demands on verbal WM.

AIMS

To investigate the association between anxiety and learning on a task which makes high demands on verbal WM.

SAMPLE

Participants were 119 typically developing, Australian elementary school children (M age = 9.25 years; SD = 7.6 months).

METHOD

In individual testing sessions, measures of trait anxiety (Spence Childhood Anxiety Scales) and state anxiety (Visual Analogue scale) were made. The Rey Auditory Verbal Learning Test, which makes similar demands on WM to many classroom activities, was administered.

RESULTS

Neither trait nor state anxiety alone was associated with mean recall across trials, however their interaction showed a significant effect. In children high on both measures of anxiety, learning followed a different trajectory. They learned more slowly on the first three trials than less anxious peers, then caught up on the remaining trials. While their mean recall scores across trials were significantly lower than those of less anxious peers, they retained as many words on the delayed learning trial.

CONCLUSION

In a group of typically developing children, learning on the early, more demanding learning trials of a verbal learning task was vulnerable to heightened anxiety. However, the extra opportunities to learn on later trials enabled more anxious children to learn as much as their less anxious peers. While they learnt less efficiently, they learnt equally effectively.

Neuro-physiological correlates of sluggish cognitive tempo (SCT) symptoms in school-aged children

This study was the first to examine the relationship between neurophysiological abnormalities and symptoms of sluggish cognitive tempo (SCT) in children. Thirty children aged 6-12 years were recruited. Their heart rate variability (HRV) was measured under resting and warning signal conditions. At rest, the children's SCT symptoms were found to be positively associated with their HRV (indicated by the standard deviation of the Poincaré plot along the line of identity in normalized units, SD2 nu). SCT symptoms were also positively associated with a change in SD2 nu between the resting and warning signal conditions. When controlling for symptoms of attention deficit hyperactivity disorder, the children's SCT symptoms were significantly predicted by their resting SD2 nu and by changes in SD2 nu and the percentage of successive RR intervals that differ by more than 50 ms (pNN50) between the resting and warning signal conditions. These findings suggest that the readiness and regulation of the autonomic nervous system may contribute to symptoms of SCT. Specifically, disturbances in the internal neurophysiological system may explain the difficulties experienced by children when exposed to environmental stimulation. These initial data support the hypothesis that SCT results from deficiencies in arousal.

Underlying Psychophysiology of Dysregulation: Resting Heart Rate and Heart Rate Reactivity in Relation to Childhood Dysregulation

OBJECTIVE

High co-occurrence of externalizing and internalizing problems could underlie inconsistent findings regarding the relation between heart rate (HR) and psychopathology. In this study, HR measures were examined in relation to a general dysregulation profile studied from variable- and person-centered approaches.

METHOD

The sample (N = 182) consisted of 8- to 12-year-old children referred for externalizing behaviors and typically developing children (mean age 9.70, SD 1.26; 75.8% boys). Resting HR (HR_rest) was assessed during a 3-minute resting period. HR reactivity (HR_reactivity) was assessed during an emotionally evoking go/no-go task.

RESULTS

From a variable-centered approach, a bifactor model was fitted with a general factor of dysregulation underlying symptoms of anxiety/depression, aggression, and attention problems. HR_rest was positively associated with dysregulation and specific aggression. From a person-centered approach, a latent profile analysis was used to identify different psychopathology classes: normative (n = 92), predominantly aggressive (n = 69), and dysregulated (n = 14). The latter was characterized by co-occurring increased levels of anxiety/depression, aggression, and attention problems. HR_rest was increased in the predominantly aggressive class and HR_reactivity was increased in the dysregulated class.

CONCLUSION

High HR_rest, or (trait-like) over-arousal, seems to be associated with dysregulation rather than uniquely associated with low externalizing or high internalizing symptomatology. In addition, HR_rest predicted greater aggression and HR_rest was increased in the predominantly aggressive class. High HR_reactivity, or enhanced emotional reactivity, might be characteristic for a clinically relevant dysregulated subgroup. Assessment of HR could provide additional knowledge on individual differences that can help refine diagnostics and intervention efforts.

Children's sustained attention to emotional facial expressions and their autonomic nervous system reactivity during parent-child interactions

The way individuals process socio-affective information is thought to impact their responses to social interactions, but research testing the relation between these processes is scarce, particularly among children. This study examined if children's attention to socio-affective stimuli was associated with their autonomic nervous system (ANS) reactivity during parent-child interactions. Children's sustained attention to facial expressions of emotion (afraid, happy, sad) was indexed using the late positive potential (LPP) event-related potential (ERP) component during a computer-based task. To measure ANS reactivity, children's respiratory sinus arrhythmia (RSA) was assessed at baseline and during positive and negative parent-child discussions. Enhanced LPP amplitudes in response to all emotional facial expressions, reflecting greater sustained attention to socio-affective stimuli, were associated with increased RSA reactivity during parent-child discussions. These results show correspondence between two psychophysiological substrates of emotion processing in healthy children and highlight how these systems may be synergistic forces contributing to emotion reactivity.

Stress reactivity in healthy child offspring of parents with anxiety disorders

Several studies suggest that anxiety disorders (AD) involve dysregulation of the autonomic nervous system (ANS) and hypothalamic-pituitary (HPA) axis. However, it is unknown if alterations in these biological systems are premorbid markers of AD risk or a state-dependent feature of anxiety. This study examined ANS and HPA-axis response to a laboratory stressor in healthy child offspring of parents with (n = 55) and without (n = 98) a history of AD. High frequency heart rate variability (HF-HRV) was assessed during sitting and standing baseline conditions and during a speech task where participants remained standing. Salivary cortisol was measured at baseline and at 15, 30, 45 and 60 min post-speech. Subjective anxiety was assessed with a visual analogue scale. Children of parents with AD displayed reduced HRV and a blunted cortisol response to the speech task compared to children of non-anxious parents. No risk group effect was found for anxiety ratings. These preliminary data suggest that healthy children of anxious parents exhibit altered stress reactivity to an acute laboratory stressor. Further research is needed to confirm findings and identify mechanisms that may account for altered self-regulation processes to a stressor in children at familial risk for AD.

Peculiarities of situational and personal anxiety degree in the schoolchildren with ENT chronic diseases

Background

A number of the QL researches in case of different pathologies are being increased during the last decade. The existing traditional research methods provide mostly arbitrary data on the disease and its treatment, which are not sufficient for the schoolchildren overall psychological and social adaptation and wellness evaluation.

Methods

The research object became schoolchildren of 3 randomly selected schools in Yerevan. 443 monitoring units formed the selection population. The degree of situational and personal anxiety was evaluated with the help of Spielberger’s and Gerbachevski’s tests.

Results

According to our research data the anxiety degree was 29,2 ± 2,3 points among the girls and 12,5 ± 1,6 points among the boys, respectively. The individual anxiety level was especially high: it made up 44,5 ± 0,8 points, and that of the situational anxiety made up 37,2 ± 0,5 points (p < 0,05).

According to Gerbachovski’s test in the group of schoolchildren with ENT pathology those with a high level of demands made up 53,5 ± 3,2%, with a medium level of demands - 32,4 ± 3,0% and with a low level of demands −14,1 ± 2,2%. A number of the practically healthy schoolchildren with a low level of demands made up 50,3%, and with a high level – 30,7%.

Conclusion

According to the investigation data those children who suffer from the ENT chronic diseases usually avoided communication, were sluggish and shy. According to the results of the research, the socio-psychological and adaptation abilities of children with the ENT chronic diseases were lower than those of the practically healthy (without ENT pathologies) coevals. This fact urges to improve the prophylactic measures provision in the mentioned pathologies aspect.
