Measurement of anxious traits: a contemporary review and synthesis

Reconceptualizing the relationship between anxiety, mindfulness, and cognitive control

Prior research has provided initial support for the claim that cognitive control mediates the relationship between anxiety and mindfulness; however, findings are often inconsistent. In this review, we argue that the inconsistency may be due to a lack of both conceptual and methodological precision in terms of how anxiety, cognitive control, and mindfulness are operationalized and assessed, and that this imprecision may be a critical source of study confounds and ambiguous outcomes. We unpack this argument by first decomposing anxiety, cognitive control, mindfulness, and relevant experimental paradigms into key dimensions in order to develop a non-unitary, multi-dimensional taxonomy of these constructs. Subsequently, we review and reinterpret the prior experimental literature, focusing on studies that examine the relationship between anxiety and cognitive control, mindfulness and cognitive control, and the three-way relationship between anxiety, mindfulness, and cognitive control. Across the reviewed studies, there was great variation in the dimensions being examined and the behavioral and/or neural measures employed; therefore, results were often mixed. Based on this review of literature, we propose a conceptually and methodologically precise framework from which to study the effects of mindfulness on cognitive control in anxiety. The framework theoretically aligns anxiety dimensions with specific mindfulness states and interventions, further suggesting how these will impact specific cognitive control dimensions (proactive, reactive). These can be assessed with experimental paradigms and associated behavioral and neural metrics to index the relevant dimensions with high precision. Novel experimental studies and tractable research designs are also proposed to rigorously test this theoretical framework.

Creative Cognitive Reappraisal Promotes Estimation Strategy Execution in Individuals with Trait Anxiety

Objectives: This study aimed to investigate the impact of the creative cognitive reappraisal on the estimation strategies execution in college students with trait anxiety. Methods: Using the Trait Anxiety Scale, 47 participants with high (HTA) and low trait anxiety (LTA) were selected from a total of 803 college students. These participants then completed a two-digit multiplication estimation task after using cognitive reappraisal to regulate negative emotions. Results: The results showed that for individuals with low trait anxiety, both standard cognitive reappraisal and creative cognitive reappraisal effectively improved their negative emotional experiences, with creative cognitive reappraisal demonstrating a superior regulatory effect. For individuals with high trait anxiety, creative cognitive reappraisal was effective in regulating negative emotions, whereas the effect of standard cognitive reappraisal on emotion regulation was not significant. Conclusions: Both standard cognitive reappraisal and creative cognitive reappraisal can enhance the speed of estimation strategy execution in college students with trait anxiety after regulating negative emotions, with creative cognitive reappraisal showing a more pronounced facilitative effect.

Non-pharmacological Interventions for Preoperative Anxiety in Children: A Systematic Review and Network Meta-Analysis

AIMS

This study aimed to compare the efficacy of non-pharmacological interventions in children with preoperative anxiety.

BACKGROUND

It is estimated that preoperative anxiety affects up to 60% of children which is associated with both immediate and long-term adverse outcomes. Several non-pharmacological interventions have been demonstrated to be effective, but further research is necessary to determine which is the most effective.

DESIGN

This study was conducted and reported in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) 2020 checklist.

METHODS

We searched randomised controlled trials in twelve databases from which inception to March 31, 2024. The primary outcome was the severity of preoperative anxiety change from the baseline to the endpoint which is usually before the anaesthesia induction. Within the frequentist framework, a random-effects network meta-analysis (NMA) was used to compare the primary outcomes. The surface under the cumulative ranking curve (SUCRA) was used to rank each intervention separately. Subgroup and sensitivity analyses were carried out for the primary outcomes.

RESULTS

A total of 36 randomised controlled trials (RCTs) with 3182 paediatric patients were included. Based on the results, psychological + digital health intervention was significantly more effective than control groups and ranked highest. Combined parental presence during induction anaesthesia and video games (PPIA + VG) had significant benefits compared to almost all other interventions with the highest rank.

CONCLUSION

Psychological + digital health interventions, especially PPIA + VG, may be the most effective non-pharmacological interventions for reducing preoperative anxiety in children. It is necessary to conduct more RCTs to evaluate the efficacy of different non-pharmacological interventions.

RELEVANCE TO CLINICAL PRACTICE

Non-pharmacological interventions can effectively improve preoperative anxiety in children.

Examination of perception of threat from emotion as mechanisms underlying the relationship between obsessive compulsive symptom dimensions and anxiety symptoms

BACKGROUND

The present study examined the mediating role of perceived threats from anxiety in the relationships among trait anxiety, state anxiety, and the obsessive-compulsive symptom dimension in obsessive-compulsive disorder (OCD).

METHODS

Patients with OCD (N = 170) completed scales assessing trait and state anxiety, OCD dimensions symptom severity, and perceived threat from anxiety with mediation analyses.

RESULTS

Perceived threat from anxiety appears to be a significant mediator between trait anxiety and harm and unacceptable thoughts symptom dimensions; perceived threat from anxiety had minimal power as a mediator in the relationship between trait anxiety and in the contamination or symmetry dimensions. However, there were no significant relationships between state anxiety and harm and mistakes, unacceptable thoughts or symmetry dimensions except for the contamination dimension.

CONCLUSIONS

The findings from our study indicate the significance of perceived threats of anxiety as a mediator function between trait anxiety and OCD symptom dimensions, which may be a maintenance factor. Enhancing the recognition of the role of cognitive mechanisms in the association between trait anxiety rather than state anxiety and different obsessive-compulsive symptom dimensions could contribute to the development of dimension-specific interventions.

Implementation of a CBT-based dental anxiety management pathway for patients with learning disabilities

Dental anxiety is a common phenomenon in the general population and may be more prevalent in people with learning disabilities. There is growing interest in the use of cognitive behaviour therapy (CBT) approaches, including within dental anxiety management. However, relatively little is known regarding the application of CBT approaches in dental anxiety management for patients with learning disabilities. This paper outlines details of the implementation of a CBT-based dental anxiety pathway for patients with learning disabilities treated in a special care dental service in England. The pathway is modelled on the utilisation of skills from the dental team (dental nurses and dentists) to deliver a combination of talking sessions, desensitisation and positive affirmation in five distinct stages. Early feedback from service users following implementation of this pathway indicates successful acceptance of dental care with a decreased use of sedative adjuncts.

Global-brain functional connectivity related with trait anxiety and its association with neurotransmitters and gene expression profiles

BACKGROUND

Numerous studies have explored the neural correlates of trait anxiety, a predisposing factor for several stress-related disorders. However, the findings from previous studies are inconsistent, which might be due to the limited regions of interest (ROI). A recent approach, named global-brain functional connectivity (GBC), has been demonstrated to address the shortcomings of ROI-based analysis. Furthermore, research on the transcriptome-connectome association has provided an approach to link the microlevel transcriptome profile with the macroscale brain network. In this paper, we aim to explore the neurobiology of trait anxiety with an imaging transcriptomic approach using GBC, biological neurotransmitters, and transcriptome profiles.

METHODS

Using a sample of resting-state fMRI data, we investigated trait anxiety-related alteration in GBC. We further used behavioral analysis, spatial correlation analysis, and postmortem gene expression to separately assess the cognitive functions, neurotransmitters, and transcriptional profiles related to alteration in GBC in individuals with trait anxiety.

RESULTS

GBC values in the ventromedial prefrontal cortex and the precuneus were negatively correlated with levels of trait anxiety. This alteration was correlated with behavioral terms including social cognition, emotion, and memory. A strong association was revealed between trait anxiety-related alteration in GBC and neurotransmitters, including dopaminergic, serotonergic, GABAergic, and glutamatergic systems in the ventromedial prefrontal cortex and the precuneus. The transcriptional profiles explained the functional connectivity, with correlated genes enriched in transmembrane signaling.

LIMITATIONS

Several limitations should be taken into account in this research. For example, future research should consider using some different approaches based on dynamic or task-based functional connectivity analysis, include more neurotransmitter receptors, additional gene expression data from different samples or more genes related to other stress-related disorders. Meanwhile, it is of great significance to include a larger sample size of individuals with a diagnosis of major depression disorder or other disorders for analysis and comparison and apply stricter multiple-comparison correction and threshold settings in future research.

CONCLUSIONS

Our research employed multimodal data to investigate GBC in the context of trait anxiety and to establish its associations with neurotransmitters and transcriptome profiles. This approach may improve understanding of the neural mechanism, together with the biological and molecular genetic foundations of GBC in trait anxiety.

Perinatal N(G)-Nitro-L-arginine methyl ester administration decreases anxiety- and depression-like behaviors in adult mice

OBJECTIVE

We hypothesized that perinatal manipulations of the nitrergic system would affect adult animal behaviors.

METHODS

We tested this hypothesis by perinatally administering N(G)-Nitro-L-arginine methyl ester (L-NAME), a non-specific antagonist of nitric oxide synthase for 15 days and assessed anxiety- and depression-like behaviors in adult mice. At 70 days of age, the mice were subjected to a battery of tests consisting of the open-field, light/dark box, forced swim, and tail-flick tests. The tests were performed at two-day intervals, and the order of the tests within the battery was determined according to the progressive invasiveness degree.

RESULTS

L-NAME-treated animals exhibited decreased anxiety-like behavior in the light/dark box and open field tests, with no change in locomotor activity. Additionally, they demonstrated decreased depression-like behavior in the forced swim test and no change in pain perception in the tail-flick test.

CONCLUSION

The nitrergic system is possibly involved in neural circuitry development that regulates behaviors since blocking perinatal nitric oxide production decreases anxiety- and depression-like behaviors in adult mice.

Sex differences in the effects of trait anxiety and age on resting-state functional connectivities of the amygdala

Background

Numerous studies characterized how resting-state functional connectivities (rsFCs) of the amygdala were disrupted in emotional disorders and varied with emotional traits, including anxiety. With trait anxiety known to diminish with age, a critical issue concerns disambiguating the effects of age and anxiety on amygdala rsFCs in studying the neural bases of individual differences in anxiety.

Methods

Two-hundred adults (83 women) 19-85 years of age underwent fMRI and assessment for trait anxiety. Amygdala rsFC correlates were identified using multiple regression with age and anxiety in the same model for all and separately in men and women. The rsFC correlates were examined for age-anxiety interaction.

Results

Anxiety was negatively correlated with amygdala-temporooccipital gyri rsFC in all and in men alone. In women, amgydala rsFC with the thalamus/pallidum, angular/supramarginal gyri, inferior temporal gyrus, and posterior insula correlated positively and rsFC with calcarine cortex and caudate correlated negatively with anxiety. We also observed sex differences in age correlation of amgydala-posterior cingulate cortex/precuneus and -insula/temporoparietal rsFCs, with stronger associations in women. In women alone, anxiety and age interacted to determine amygdala rsFC with the thalamus/pallidum, calcarine cortex, and caudate, with older age associated with stronger correlation between anxiety and the rsFCs.

Limitations

The findings need to be validated in an independent sample and further explored using task-based data.

Conclusion

Highlighting anxiety- and age- specific as well as interacting correlates of amygdala rsFCs and sex differences in the correlates, the findings may shed light on the neural markers of anxiety.

Towards the effects of translators' emotional intelligence and anxiety on their translation quality

For years, the impact of translators and their emotional characteristics on translation quality have been the main concern of scholars. That is, few studies have evaluated the role of translators' qualities on their professional performance. It is because most translation studies have focused on the linguistic and sociolinguistic determinants of translation quality. To highlight the consequences of translators' emotional characteristics on their professional performance, this study sought to review the role of translators' emotional intelligence and anxiety on their translation quality. As evidenced by previous investigations, both emotional intelligence and anxiety can enormously affect the quality of translations. This review offers some takeaways for educators in translation studies as well as the translation educational system to make them cognizant of the role of emotional intelligence in translation quality. It also recommends some solutions to avoid the adverse effects of anxiety on translation quality.

Appropriateness of the anxiety subscale of the Hospital Anxiety and Depression Scale for Koreans to measure preoperative anxiety and the effect of preoperative anxiety on postoperative quality of recovery

BACKGROUND

The reliability and validity of the anxiety subscale of the Hospital Anxiety and Depression Scale for Koreans (K-HADS-A) has not been studied in Korean surgical patients. This study aimed to validate the usefulness of K-HADS-A for measuring preoperative anxiety in Korean surgical patients. Additionally, the effect of preoperative anxiety on postoperative quality of recovery was evaluated.

METHODS

Preoperative anxiety in 126 inpatients with planned elective surgery was measured using the K-HADS-A. The postoperative quality of recovery was measured using the Korean version of the Quality of Recovery-15. The validity and reliability of the K-HADS-A were evaluated. The differences in quality of recovery on the first and seventh day postoperatively were then compared between the anxious and non-anxious groups.

RESULTS

There was a statistical correlation between the K-HADS-A and Anxiety Likert Scale. The goodness-of-fit indices of the structural equation model showed how well the data from the K-HADS-A match their concept. The Kaiser-Meyer-Olkin value was 0.848, and the P value of Bartlett's test of sphericity was < 0.001. Cronbach's alpha was high at 0.872. The K-HADS-A had an acceptable level of validity and reliability. Postoperative quality of recovery was significantly lower in the anxious group (postoperative day 1: t = 2.058, P = 0.042; postoperative day 7: t = 3.430, P = 0.002).

CONCLUSIONS

The K-HADS-A is an acceptable tool for appropriately assessing preoperative anxiety in Korean surgical patients. Assessing preoperative anxiety is valuable, because preoperative anxiety affects the postoperative quality of mental and physical recovery.

Cognitive Symptoms Link Anxiety and Depression Within a Validation of the German State-Trait Inventory for Cognitive and Somatic Anxiety (STICSA)

Background

In the present study we aimed to develop a German version of the State-Trait Inventory for Cognitive and Somatic Anxiety (STICSA) and evaluate the psychometric properties. Associations of cognitive and somatic anxiety with other measures of anxiety, depression, and stress, elucidating possible underlying functional connections, were also examined, as symptoms of anxiety, depression and stress often overlap.

Method

Two samples (n1 = 301; n2 = 303) were collected online and in the lab, respectively. Dynamic connections between somatic and cognitive anxiety, other measures of anxiety, depression, and stress, were analyzed using a network approach. Psychometric analyses were conducted using exploratory and confirmatory factor analyses.

Results

We replicated and validated the two-factorial structure of the STICSA with the German translation. Network analyses revealed cognitive trait anxiety as the most central node, bridging anxiety and depression. Somatic trait anxiety exhibited the highest discriminant validity for distinguishing anxiety from depression.

Conclusion

The central role of cognitive symptoms in these dynamic interactions suggests an overlap of these symptoms between anxiety and depression and that differential diagnostics should focus more on anxious somatic symptoms than on cognitive symptoms. The STICSA could therefore be useful in delineating differences between anxiety and depression and for differential assessment of mood and anxiety symptoms. Additional understanding of both cognitive and somatic aspects of anxiety might prove useful for therapeutic interventions.

Anxiety in Brief: Assessment of the Five-Item Trait Scale of the State-Trait Anxiety Inventory in South Africa

The current study examined the psychometric properties of a short form of the trait scale of the Spielberger State-Trait Anxiety Inventory. Participants consisted of a convenience sample of students (n = 322) who completed the five-item version of the trait scale of the State-Trait Anxiety Inventory, the Perceived Stress Scale, the nine-item version of the Beck Hopelessness Scale, the 10-item version of the Center for Epidemiological Studies Depression Scale, and the Post-Traumatic Stress Disorder Checklist. We used classical test theory and item response theory (Rasch and Mokken analyses) to examine the psychometric properties of a previously proposed five-item version of this scale. These approaches confirmed that the five-item measure of anxiety had satisfactory reliability and validity, and also confirmed that the five items comprised a unidimensional scale.

Serum BDNF levels are involved in the diagnosis and treatment response in patients with PD

BACKGROUND

The study aimed to explore whether brain-derived neurotrophic factor (BDNF) could be predictive for the diagnosis of panic disorder (PD) and to explore the association between serum BDNF levels and the treatment response to escitalopram in PD patients.

METHODS

Ninety PD patients and 99 healthy controls (HCs) were finally recruited. PD patients were treated only by escitalopram for 8 weeks. All patients were administered the Short-Form Health Survey-36 (SF-36), Hamilton Anxiety Rating Scale (HAMA-14), and State-Trait Anxiety Inventory (STAI) to assess life quality, anxiety symptoms and trait, respectively. Neuropsychological tests were assessed at baseline in all participants. Besides, peripheral venous blood was drawn from all participants for BDNF serum levels detection both at baseline and after 8 weeks of treatment.

RESULTS

In PD patients, the baseline serum BDNF levels were lower than HCs. The area under the ROC curve (AUC) of baseline serum BDNF levels predicting PD from HCs was 0.947 (94.9 % for sensitivity, 77.8 % for specificity). The baseline serum BDNF levels (beta = 0.276, p = 0.007), the current duration (beta = -0.301, p = 0.004), and trait anxiety (TAI) (beta = 0.201, p = 0.045) were predictors for reduction rates of HAMA-14 after 8 weeks' escitalopram treatment.

LIMITATIONS

A long-term observation and high homogeneity of sample may make the results more convincing.

CONCLUSION

This preliminary finding highlighted the value of serum BDNF levels for the diagnosis of PD. In addition, the higher baseline serum BDNF levels may predict the better escitalopram treatment response in PD patients.

The elevated metabolic cost of walking at preferred speeds of healthy elderly on treadmills compared to overground is not related to increased self-reported anxiety

PURPOSE

To investigate whether the elevation in metabolic cost of walking on treadmills compared to overground for healthy elderly is related to self-reported anxiety and if changes in self-reported anxiety are related to changes in heart rate.

METHODS

We measured overground preferred walking speed, oxygen consumption rate and heart rates during rest and walking, and self-reported anxiety in 10 elderly (mean age 69.5 ± 3.1 years, 8 males and 2 females). At their preferred speed, the participants first walked overground, then on a high treadmill, and then on a low treadmill. Gross and Net metabolic costs of walking were calculated from the rates of oxygen consumption.

RESULTS

Gross and net metabolic cost of walking were higher (p < 0.05) on high treadmill (net cost: 2.64 J kg^-1 m^-1) and low treadmill (net cost: 2.68 J kg^-1 m^-1) compared to overground (net cost: 2.44 J kg^-1 m^-1), and the same was true for heart rate. There were no significant differences (p > 0.05) in metabolic costs and heart rates between the two treadmill conditions. Self-reported anxiety was higher on the high treadmill compared to overground (p = 0.004) and compared to low treadmill (p = 0.02). We found no significant difference (p > 0.05) for self-reported anxiety between overground and the low treadmill.

CONCLUSION

These results show that treadmill walking cannot be adequately generalized to overground walking. The differences found in metabolic cost on treadmills compared to overground were not related to differences in self-reported anxiety. Furthermore, the changes in heart rate are not related to changes in self-reported anxiety.

Pavlovian Disgust Conditioning and Generalization: Specificity and Associations With Individual Differences

Although studies have identified differences between fear and disgust conditioning, much less is known about the generalization of conditioned disgust. This is an important gap in the literature given that overgeneralization of conditioned disgust to neutral stimuli may have clinical implications. To address this knowledge gap, female participants (n = 80) completed a Pavlovian conditioning procedure in which one neutral food item (conditioned stimulus; CS+) was followed by disgusting videos of individuals vomiting (unconditioned stimulus; US) and another neutral food item (CS-) was not reinforced with the disgusting video. Following this acquisition phase, there was an extinction phase in which both CSs were presented unreinforced. Importantly, participants also evaluated generalization stimuli (GS+, GS-) that resembled, but were distinct from, the CS after each conditioning phase. As predicted, the CS+ was rated as significantly more disgusting and fear inducing than the CS- after acquisition and this pattern persisted after extinction. However, disgust ratings of the CS+ after acquisition were significantly larger than fear ratings. Participants also rated the GS+ as significantly more disgusting, but not fear inducing, than the GS- after acquisition. However, this effect was not observed after extinction. Disgust proneness did predict a greater increase in disgust and fear ratings of the CS+ relative to the CS- after acquisition and extinction. In contrast, trait anxiety predicted only higher fear ratings to the CS+ relative to the CS- after acquisition and extinction. Disgust proneness nor trait anxiety predicted the greater increase in disgust to the GS+ relative to the GS- after acquisition. These findings suggest that while conditioned disgust can generalize, individual difference variables that predict generalization remain unclear. The implications of these findings for disorders of disgust are discussed.

Anxiety in the Classroom: Only Girls' Anxiety Is Related to Same-Sex Peers' Anxiety

Many teens report experiencing anxiety in school, which can negatively impact their well-being. Considering that adolescents tend to adopt the same behaviors as their classmates with whom they spend, on average, 923 h every year, the current exploratory study (1) assessed whether an association exists between a student’s state anxiety score and his/her classmates’ average trait anxiety scores and (2) examined whether this association differed between boys and girls, as well as between elementary school and high school students. During two consecutive school years, 1044 Canadian students (59% girls) from six elementary schools (aged 10−12) and seven high schools (aged 15−17) completed the State-Trait Anxiety Inventory for Children. Multilevel analyses revealed a same-sex peer effect of classmates’ anxiety in girls only (β = 0.40, p < 0.001). This effect was similar for elementary and high school girls (β = 0.07, p = 0.27). Interestingly, no association was found for boys, same-sex peers (β = 0.11, p = 0.25), or opposite-sex peers (β = −0.01, p = 1.00). Our results suggest that factors related to sex may reinforce anxiety in school settings. Future studies should confirm these results and explore the mechanisms involved in this sex-specific difference.

Effects of maternal deprivation and environmental enrichment on anxiety-like and depression-like behaviors correlate with oxytocin system and CRH level in the medial-lateral habenula

The medial-lateral habenula (LHbM)'s role in anxiety and depression behaviors in female mice remains unclear. Here, we used neonatal maternal deprivation (MD) and post-weaning environmental enrichment (EE) to treat female BALB/c offspring and checked anxiety-like and depression-like behaviors as well as the corticotropin-releasing hormone (CRH), oxytocin receptor (OTR), estrogen receptor-beta (ERβ) levels in their LHbM at adulthood. We found that MD enhanced state anxiety-like behaviors in the elevated plus-maze test, and EE caused trait anxiety-like behaviors in the open field test and depression-like behaviors in the tail suspension test. The immunochemistry showed that MD reduced OT immunoreactive neuron numbers in the hypothalamic paraventricular nucleus but increased OTR levels in the LHbM; EE increased CRH levels in the LHbM but decreased OTR levels in the LHbM. The additive effects of EE and MD maintained the behavioral parameters, OT-ir neuronal numbers, CRH levels, and OTR levels similar to the additive of non-MD and non-EE. The correlation analysis showed that CRH levels correlated with synaptic connection levels, OTR levels correlated with nucleus densities, and ERβ levels correlated with Nissl body levels and body weights in female mice. Neither MD nor EE affected ERβ levels in the LHbM. Together, the study revealed the relationships between behaviors and neuroendocrine and neuronal alterations in female LHbM and the effects of experiences including MD and EE on them.

The role of English as a foreign language learners’ grit and foreign language anxiety in their willingness to communicate: Theoretical perspectives

Learners’ willingness to communicate in a foreign language is regarded as a critical issue in educational contexts, so the role of emotional factors in learners’ willingness to communicate has drawn the attention of investigators. This review investigated the studies on the relationship between English as a Foreign Language (EFL) learners’ grit, foreign language anxiety, and willingness to communicate. This review showed a significant relationship between learners’ grit and willingness to communicate. The earlier studies showed that gritty learners with incessant inspiring efforts are more likely to communicate in a foreign language. This review also indicated that lower anxious learners tend to have more willingness to communicate. Earlier studies also indicated that the theories, such as broaden-and-build, positive psychology, dynamic system, affective filter, and attentional control can justify the relationships between these constructs. Moreover, the study has some pedagogical implications and suggestions for teachers, learners, syllabus designers, material developers, teacher educators, policy-makers, and advisors. The ideas can improve their awareness of teachers’ willingness to communicate, grit, and foreign language anxiety in educational environments.

The Influence of Emotion Regulation on Estimation Strategy Execution in Individuals with Trait Anxiety

Previous studies have shown that some negative emotions hinder estimation strategy execution. However, these studies rarely investigate the influence of negative emotions on the estimation strategy execution in individuals with trait anxiety. The present study examines the relationship between negative emotions and trait anxiety in individuals’ estimation strategy execution. Moreover, it looks into the influence of different emotion regulation strategies on their estimation strategy execution. In October 2010, 803 college students were evaluated using the Trait Anxiety Scale. From these participants, individuals with high and low trait anxiety were selected to complete the double-digit multiplication estimation task. The results showed that the estimation strategy’s execution speed in individuals with high trait anxiety was slower than those with low trait anxiety under negative emotions (t (113) = −2.269, p = 0.025, d = 0.427). Both expression inhibition and cognitive reappraisal could significantly improve the execution speed of the estimation strategy in low trait anxiety (p < 0.001). For individuals with high trait anxiety, cognitive reappraisal regulating negative emotions can promote the estimation strategy’s execution speed (p = 0.031). However, the use of expression inhibition has no significant effect on estimation strategy execution (p = 0.101). In summary, the present study revealed that different emotion regulation strategies moderated the arithmetic strategy execution of individuals with trait anxiety, and cognitive reappraisal had a better effect in individuals with high trait anxiety.

Associations between general trait anxiety, trait social anxiety and cardiovascular responses to social and non-social stressors

OBJECTIVE

The present study sought to examine whether anxiety propensity dimensions (general trait anxiety vs. trait social anxiety) interact with stressor types (tasks with social vs. non-social challenges) to determine cardiovascular stress responses.

METHODS

A 2 × 3 mixed-factorial experimental design was employed. The State-Trait Anxiety Inventory, the Social Performance and Social Interaction Anxiety Scales were administered to 233 participants, who engaged in a stress task with either social or non-social challenges during which their cardiovascular data were continuously collected.

RESULTS

General trait anxiety negatively predicted heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP) reactivity (β = -0.16, p = 0.001; β = -0.17, p = 0.001; β = -0.18, p < 0.001), and positively predicted HR, SBP, DBP recovery (β = 0.16, p = 0.012; β = 0.15, p = 0.014; β = 0.15, p = 0.011), regardless of stress types. Social performance anxiety (β = -0.23, p = 0.002; β = -0.25, p = 0.001; β = -0.24, p = 0.001) and social interaction anxiety (β = -0.22, p < 0.001; β = -0.25, p < 0.001; β = -0.22, p < 0.001) only negatively predicted HR, SBP, DBP reactivity to the stress task with social challenges. No associations were observed between trait social anxiety and cardiovascular recovery from the stress task with social or non-social challenges.

CONCLUSIONS

These findings suggest that different trait anxiety dimensions interact with stressor types in affecting cardiovascular stress responses, which have different health implications.

Neonatal D-fenfluramine treatment promotes long-term behavioral changes in adult mice

Serotonin exerts a significant role in the mammalian central nervous system embryogenesis and brain ontogeny. Therefore, we investigate the effect of neonatal treatment of d-fenfluramine (d-FEN), a serotonin (5-HT) releaser, on the behavioral expression of adult male Swiss mice. For this purpose, we divided pregnant female Swiss mice into two groups (n = 6 each and ~35 g). Their offspring were treated with d-FEN (3 mg/kg, s.c.) from postnatal days (PND) 5 to 20. At PND 21, one male puppy of each litter was euthanized; the midbrain and the hippocampus were dissected for RNA analysis. At PND 70, the male offspring underwent a behavioral assessment in the open field, elevated plus-maze, light-dark box, tail suspension, and rotarod test. The programmed animals had a decrease in 5HT1a, serotonin transporter (SERT), and brain-derived neurotrophic factor (BDNF) expression in the mesencephalic raphe region. Alternatively, there was a reduction only in the tryptophan hydroxylase (TPH2) and BDNF expression in the hippocampus. In the light-dark box test, offspring of the treated group had higher latency to light and less time on the light side than the control. Also, it was observed less time of immobility in the tail suspension test. We also observed low motor skill learning in the rotarod test. These findings suggest that programming with d-FEN during the neonatal period alters a mesencephalic and hippocampal serotonergic system, promoting anxiety, antidepressant behavior, low coordination, and motor learning in adults.

Pandemic-activated psychological growth: significance of extraversion, self-consciousness and COVID-19 related anxiety

BACKGROUND

The sense of threat to health and life in the face of a pandemic, accompanied by difficulties imposed by lockdown, may trigger a serious crisis. Among possible consequences of such a crisis may paradoxically be the phenomenon of psychological growth. The aim of this article is to identify predictors of pandemic-activated psychological growth (PPG). The relationships between extraversion, reflective and ruminative self-consciousness and PPG were the subject of our inquiry. Additionally, a question was posed about the indirect effect of self-consciousness on PPG through anxiety.

PARTICIPANTS AND PROCEDURE

The study involved 1206 participants aged 18 to 26 years, who declared that the pandemic situation significantly threatened their important life goals. Procedure: cross-sectional design. Four online short questionnaire-measures were used: the Ten-Item Personality Inventory (TIPI), the Rumination-Reflection Questionnaire (RRQ), the Current Self-disposition Scale (CSS), and the Post-traumatic Growth Inventory (PTGI).

RESULTS

Extraversion and reflective self-consciousness were direct predictors of higher PPG, whereas ruminative self-consciousness was directly related to a lower PPG. There was an indirect effect of ruminative self-consciousness on PPG through COVID-19 related anxiety.

CONCLUSIONS

Although the results do not confirm the permanence of a growth effect, finding PPG predictors considered as beneficial resources for coping with difficult pandemic circumstances appears to be valuable in the current state of affairs.

Computational modeling of threat learning reveals links with anxiety and neuroanatomy in humans

Influential theories implicate variations in the mechanisms supporting threat learning in the severity of anxiety symptoms. We use computational models of associative learning in conjunction with structural imaging to explicate links among the mechanisms underlying threat learning, their neuroanatomical substrates, and anxiety severity in humans. We recorded skin-conductance data during a threat-learning task from individuals with and without anxiety disorders (N=251; 8-50 years; 116 females). Reinforcement-learning model variants quantified processes hypothesized to relate to anxiety: threat conditioning, threat generalization, safety learning, and threat extinction. We identified the best-fitting models for these processes and tested associations among latent learning parameters, whole-brain anatomy, and anxiety severity. Results indicate that greater anxiety severity related specifically to slower safety learning and slower extinction of response to safe stimuli. Nucleus accumbens gray-matter volume moderated learning-anxiety associations. Using a modeling approach, we identify computational mechanisms linking threat learning and anxiety severity and their neuroanatomical substrates.

When the approaching threat is uncertain: Dynamics of defensive motivation and attention in trait anxiety

Uncertainty of threat has been linked to anxiety, but little is known about how neurophysiological responses change as uncertain threats approach and whether trait anxiety modulates these changes. The current study was designed to explore aspects of the dynamics of defensive motivation (startle reflex elicited by acoustic startle probes), attention (probe N100 component of event-related potentials elicited by acoustic startle probes), and autonomic nervous system activity (heart rate) when the approaching threat was certain or uncertain in a variant of the threat probability task. Behavioral results showed that high-trait anxious individuals reported higher levels of anxiety than low-trait anxious individuals only under the uncertain threat condition. Electromyographic data showed that high-trait anxious individuals tended to produce a more pronounced startle reflex, especially when the uncertain threat was proximal. This pattern was not observed in low-trait anxious individuals. By examining early attention engagement through probe N100, we observed a similar pattern in relation to defensive motivation. Moreover, under the uncertain threat condition, high-trait anxious individuals yielded a greater deceleration of heart rate than low-trait anxious individuals. These results indicate a distinct modulation effect of trait anxiety in the dynamics of defensive motivation, attention, and the autonomic nervous system during the anticipation of uncertain threats.

An evaluation of anxiety disorder and emotion regulation difficulty in children and adolescents with alopecia areata

Context:

The relationship between alopecia areata (AA) and emotion regulation difficulty has not yet been fully explained.

Aims:

The aim of the study was to investigate the levels of anxiety and emotion regulation difficulty in children diagnosed with AA.

Settings and Design:

This case-control study was done in the university setting.

Methods:

Behavioral tests measuring anxiety and emotion regulation difficulties, and the measures assessing AA severity were applied to 32 AA patients consulted at Dermatology Clinic of Yozgat Bozok University. A control group was formed of 36 healthy children.

Statistical Analysis Used:

Kolmogorov-Smirnov normality test, Mann-Whitney U test and Pearson's and Fisher's Chi-square tests and Spearman's correlation test.

Results:

Evaluation was made of a total of 68 subjects (32 patients, 36 healthy subjects). The Difficulties in Emotion Regulation Scale (DERS)-total score and the DERS-clarity subscore were statistically significantly higher in the control group than in the patient group (P = 0.021, P = 0.003, respectively). No significant difference was determined between the two groups in respect of anxiety levels. No correlation was determined between disease severity and the scales. It was determined that as disease duration increased, so the DERS-non-acceptance subscale score increased, and with an increase in age, the SAI score of the AA patients increased. The DERS-impulse subscale score was seen to be statistically significantly higher in the boys with AA than in girls (P = 0.030).

Conclusions:

The results of this study showed that a visible, chronic, recurrent disease such as AA is not always seen with high psychiatric comorbidity and that together with the presence of the disease, patient age and disease duration are also important. It can be considered that AA may have been affected by the location, time and conditions of the study.

The risk and protective factors of heightened prenatal anxiety and depression during the COVID-19 lockdown

While pregnant women are already at-risk for developing symptoms of anxiety and depression, this is heightened during the COVID-19 pandemic. We compared anxiety and depression symptoms, as indicators of psychological distress, before and during COVID-19, and investigated the role of partner, social network and healthcare support on COVID-19-related worries and consequently on psychological distress. A national survey, conducted during the first lockdown in The Netherlands, assessed COVID-19 experiences and psychological distress (N = 1421), whereas a comparison sample (N = 1439) was screened for psychological distress in 2017-2018. During COVID-19, the percentage of mothers scoring above the questionnaires' clinical cut-offs doubled for depression (6% and 12%) and anxiety (24% and 52%). Women reported increased partner support during COVID-19, compared to pre-pandemic, but decreased social and healthcare support. Higher support resulted in lower COVID-19-related worries, which in turn contributed to less psychological distress. Results suggest that a global pandemic exerts a heavy toll on pregnant women's mental health. Psychological distress was substantially higher during the pandemic than the pre-pandemic years. We identified a protective role of partner, social, and healthcare support, with important implications for the current and future crisis management. Whether increased psychological distress is transient or persistent, and whether and how it affects the future generation remains to be determined.

Anomalous static and dynamic functional connectivity of amygdala subregions in individuals with high trait anxiety

BACKGROUND

Trait anxiety is considered a susceptible factor for stress-related disorders, and is characterized by abnormal brain activity and connectivity in the regions related to emotional processing (e.g., the amygdala). However, only a few studies have examined the static and dynamic changes of functional connectivity in trait anxiety.

METHOD

We compared the resting-state static and dynamic functional connectivity (sFC/dFC) in individuals with high trait anxiety (HTA, n = 257) and low trait anxiety (LTA, n = 264) using bilateral amygdala subregions as the seeds, that is, the centromedial amygdala (CMA), basolateral amygdala (BLA), and superficial amygdala (SFA).

RESULTS

The CMA, BLA, and SFA all showed reduced sFC with the executive control network (ECN) and anomalous dFC with the default mode network (DMN) in individuals with HTA. The CMA only showed reduced sFC with the ECN and reduced dFC with the DMN in individuals with HTA. The BLA showed reduced sFC with the salience network (mainly in the anterior and median cingulate), and increased dFC between the BLA and the DMN in individuals with HTA compared to those with LTA. Notably, HTA showed widespread anomalous functional connectivity in the SFA, including the visual network, mainly in the calcarine fissure, limbic system (olfactory cortex), and basal ganglia (putamen).

CONCLUSION

The anomalous sFC and dFC in individuals with HTA may reflect altered mechanisms in prefrontal control, salient stimuli processing, and amygdaloidal responsivity to potential threats, leading to alterations in associative, attentional, interpretative, and regulating processes that sustain a threat-related processing bias in HTA individuals.

Measures of emotion regulation: Convergence and psychometric properties of the difficulties in emotion regulation scale and emotion regulation questionnaire

OBJECTIVE

Investigating unique and shared aspects of measures of emotion regulation (ER) advances our understanding of ER as a multidimensional construct. This study aimed to investigate psychometric properties of three ER-measures: Difficulties in Emotion Regulation Scale (DERS-36), the abbreviated version DERS-16, and Emotion Regulation Questionnaire (ERQ).

METHODS

In a community sample (N = 843; 56% females) we investigated their internal consistency, factor structure, convergence, and association with symptoms of depression, anxiety, stress and substance abuse.

RESULTS

The proposed factor structures of the DERS-16 and the ERQ demonstrated an adequate fit. There were moderate correlations between the two DERS versions (36 and 16) and ERQ subscales Reappraisal and Suppression. Total scores of DERS-36 and DERS-16 demonstrated preferential associations with depression and anxiety. Corresponding associations between ERQ subscales and psychiatric symptoms were weak.

CONCLUSION

The results indicate that DERS-16 could be useful as an alternative, easily administered measure of ER difficulties.

Emotion and Emotion Preferences in Daily Life: The Role of Anxiety

People vary in their emotion preferences (i.e., desired emotional states). No study, however, has examined the nature of emotion preferences in anxiety. The current study utilized a 14-day ecological momentary assessment (EMA) paradigm to investigate the daily dynamics of emotion preferences and state emotion as they relate to individual differences in trait anxiety and anxiety symptom severity. Individuals with higher levels of trait anxiety and with more severe anxiety symptoms report greater preferences for state anxiety compared to their low anxiety counterparts. Relations between anxiety preferences and subsequent anxiety vary as a function of trait anxiety and symptom severity, and different associations are observed between the two measures of anxiety. The current findings suggest that aberrant emotion preferences may contribute to emotion dysfunction in anxiety, and highlight emotion preferences as a novel treatment target for interventions that aim to improve emotion functioning among people with elevated levels of anxiety.

The emotional heart: prospective associations of anger, depression, and anxiety as risk factors for myocardial infarction in a 22-year follow-up of a working cohort of middle-aged men

Aim

The study aim was to further clarify the relationship between psychological factors and myocardial infarction (MI) by simultaneously examining anger, depression, and anxiety as risk factors for incident MI in a healthy working sample.

Subject and method

Baseline measurements of psychological variables were assessed through a self-reported questionnaire in a healthy cohort of 968 middle-aged men working at the Volvo Corporation. Single-item questions assessed depression and anxiety. Anger was assessed by the Trait Anger subscale of the Spielberger State-Trait Anger Expression Inventory. The endpoint was incident MI verified by national registers or medical records with follow up after 22 years. The main outcome was computed through logistic regression, reported as odds ratios. Additional correlation analyses were performed between psychological variables and coronary risk factors.

Results

None of the psychological variables was significantly associated with the outcome; thus, the results failed to show an association between anger, depression, or anxiety and incident MI in this sample. There were some significant, but weak, correlations between psychological factors and negative health behaviors. Other components of traditional risk scoring instruments did not correlate with the psychological factors.

Conclusion

A cohort restricted to middle-age healthy men limits applicability. However, our failure to replicate earlier results of population samples suggests a need for further research on associations between psychological factors and MI in healthy samples.

Effect of media distraction (audio-visual and music) for pain and anxiety control in patients undergoing shock-wave lithotripsy: A systematic review and meta-analysis

Audio-visual (AV) or music distraction may be used to reduce pain during several healthcare procedures. The present manuscript is a systematic review and meta-analysis to assess the effectiveness of media distraction in reducing pain and anxiety in extracorporeal shock wave lithotripsy (ESWL) patients. The PubMed, Embase, Scopus, BioMed Central, Ovoid and CENTRAL (Cochrane Central Register of Controlled Trials) databases were screened for studies assessing the role of media distraction (music/AV media) in reducing pain and anxiety of ESWL patients. Data were summarized using the mean difference (MD) with 95% confidence intervals (CI). A total of 11 randomized controlled trials were included. Pooled analysis indicated a statistically significant difference in pain outcomes with media distraction [mean difference (MD): -1.18; 95% CI: -2.35, -0.01; I²=96.8%)]. Subgroup analysis indicated that both AV media (MD: -2.94; 95% CI: -4.70, -1.17; I²=79.2%) and music (MD: -0.86; 95% CI: -1.37, -0.35; I²=62.5%), led to significant reduction in pain outcomes. Pooled analysis indicated a statistically significant reduction of anxiety scores with the use of media distraction (MD: -3.91; 95% CI: -6.44, -1.38; I²=77.7%). To conclude, the present review suggests that media distraction in the form of AV media or music may be beneficial in reducing the pain and anxiety of patients undergoing ESWL. Evidence is, however, weak considering the small effect size, confidence intervals being close to zero, and instability of the results on sensitivity analysis. In clinical practice, media distraction may be used during ESWL as a nursing intervention, but a clinically important reduction of pain and anxiety may not be expected.

The Role of Cognitive Complaints in the Relationship Between Trait Anxiety, Depressive Symptoms, and Subjective Well-Being and Ill-Being in Adult Community Volunteers

PURPOSE

Trait anxiety, depressive symptoms, and cognitive complaints affect mental health. The mediating role of cognitive complaints has been reported recently. However, the mediating effects of cognitive complaints in the relationships between trait anxiety, depressive symptoms, and subjective well-being (SWB) and ill-being (SIB) remain unknown. Therefore, we used path analyses to investigate these mediating effects.

MATERIALS AND METHODS

A total of 554 adult community volunteers in Japan were studied using the State-Trait Anxiety Inventory (Form Y), Patient Health Questionnaire-9, Cognitive Complaints in Bipolar Disorder Rating Assessment, and Subjective Well-Being Inventory. These assessment tools evaluated trait anxiety, depressive symptoms, cognitive complaints, SWB, and SIB. Path analyses were performed in this study.

RESULTS

Path analyses revealed that there were significant indirect effects, via cognitive complaints, of trait anxiety and depressive symptoms on SIB. However, there were no significant indirect effects of trait anxiety and depressive symptoms on SWB. There were significant indirect effects, via depressive symptoms, of trait anxiety on cognitive complaints, SWB, and SIB.

CONCLUSION

The role of cognitive complaints may be different between SWB and SIB associated with trait anxiety and depressive symptoms. Evaluating the mediating effect of cognitive complaints may be more useful on SIB than SWB associated with trait anxiety and depressive symptoms. These findings may be useful when considering intervention targets in mental health.

Specificity of trait anxiety in anxiety and depression: Meta-analysis of the State-Trait Anxiety Inventory

The State-Trait Anxiety Inventory - Trait version (STAI-T) was developed to measure an individual's tendency to experience anxiety, but it may lack discriminant evidence of validity based on strong observed relationships with measures of depression. The present series of meta-analyses compares STAI-T scores among individuals with depressive disorders, anxiety disorders, and nonclinical comparison groups, as well as correlations with measures of anxiety and depressive symptom severity, in order to further examine discriminant and convergent validity. A total of 388 published studies (N = 31,021) were included in the analyses. Individuals with an anxiety disorder and those with a depressive disorder displayed significantly elevated scores on the STAI-T compared to nonclinical comparison groups. Furthermore, anxiety and depressive symptom severity were similarly strongly correlated with the STAI-T (mean r = .59 - .61). However, individuals with a depressive disorder had significantly higher STAI-T scores than individuals with an anxiety disorder (Hedges's g = 0.27). Given these findings, along with previous factor analyses that have observed a depression factor on the STAI-T, describing the scale as a measure of 'trait anxiety' may be a misnomer. It is proposed that the STAI-T be considered a non-specific measure of negative affectivity rather than trait anxiety per se.

Dimensionality of the State-Trait Inventory of Cognitive and Somatic Anxiety

The State-Trait Inventory of Cognitive and Somatic Anxiety (STICSA) is a commonly administered self-report instrument of state-trait cognitive and somatic anxiety. Extant research has consistently supported the intended oblique two-factor scoring structure for the STICSA. However, this model assumes that population-level data have (or approximate) a simple structure and that item-level variance is unidimensional. These assumptions may not be tenable and have unintended consequences for STICSA subscore interpretation. Consequently, we tested these assumptions by fitting confirmatory and exploratory structural equation models to STICSA scores for a diverse sample of college students enrolled at a large Southwestern university in the United States (n = 635). Results indicated that cognitive and somatic factors are not equally robust and that STICSA items appear to measure a nonnegligible mixture of both latent cognitive and somatic anxiety. It is recommended that future research use exploratory structural equation model in tandem with CFA to directly model data complexity.

Mexican pregnant women show higher depression and anxiety with rising age and in the case of being single

Background

Pregnancy is an important predisposition period to develop anxiety and depression, with a direct impact on the woman's offspring. The aim of this study was to report the correlation between depression and anxiety in pregnant women and its association with the marital status and age.

Materials

A  descriptive, retrospective and cross-sectional study was conducted in the outpatient care of the Psychology Service at the "Mónica Pretelini Sáenz" Maternal Perinatal Hospital (HMPMPS), Toluca, Mexico, from June 2012 to March 2019. As routine, the  Beck Depression Inventory (BDI-II) and the  Beck Anxiety Inventory-Trait (BAIT), were applied to all women seeking attention at the  HMPMPS. Only pregnant patients were selected for this study, with the women referred for the first time to the external Psychology Clinic as inclusion criteria. Pearson's correlation coefficient and the frequency of cases for age, BDI-II, and BAIT were obtained using the IBM SPSS Statistics ^® v.23 software.

Results

The  study included 2947 pregnant patients with a mean age of 28.6 ± 6.9 years. Of these, 2616 (88.8%) presented with mild anxiety, 269 (9.1%) with moderate, and 62 (2.1%) with severe anxiety. On the other hand, 2149 (72.9%) patients presented with minimal depression, 341 (11.6%) mild depression, 268 (9.1%) moderate depression, and 189 (6.4%) had severe depression. The correlations between age and BDI-II was -0.026 (P = 0.152), between age and BAI was -0.038 (P = 0.037), and between BAIT and BDI-II 0.650 (P ≤ 0.001).

Conclusions

The age group with the highest frequency of depression and anxiety was from 20 to 29 years. The absence of a stable partner represented an important risk factor for anxiety and depression during pregnancy.

Reference values of conditioned pain modulation

Background and aims Endogenous pain modulation can be studied in humans by conditioned pain modulation (CPM): pain induced by a test stimulus is attenuated by a distantly applied noxious conditioning stimulus. The detection of impaired CPM in individual patients is of potential importance to understand the pathophysiology and predict outcomes. However, it requires the availability of reference values. Methods We determined reference values of CPM in 146 pain-free subjects. Pressure and electrical stimulation were the test stimuli. For electrical stimuli, we recorded both pain threshold and threshold for the nociceptive withdrawal reflex. Cold pressor test was the conditioning stimulus. The 5th, 10th and 25th percentiles for the three tests were computed by quantile regression analyses. Results The average thresholds increased after the conditioning stimulus for all three tests. However, a subset of subjects displayed a decrease in thresholds during the conditioning stimulus. This produced negative values for most of the computed percentiles. Conclusions This study determined percentile reference values of CPM that can be used to better phenotype patients for clinical and research purposes. The negative value of percentiles suggests that a slightly negative CPM effect can be observed in pain-free volunteers. Implications Pain facilitation rather than inhibition during the conditioning stimulus occurs in some pain-free volunteers and may not necessarily represent an abnormal finding.

Do State and Trait Measures Measure States and Traits? The Case of Community-Dwelling Caregivers of Older Adults

Spielberger’s state and trait anxiety and anger scales are widely used and documented, but there is little or no direct evidence that they actually measure their respective state and trait aspects as was intended. We conducted latent state-trait analyses on data collected from 310 community-dwelling caregivers of older adult care recipients and found that (a) both state and trait scales reflected a mixture of state and trait aspects of their latent constructs, (b) state scales reflected more state-like variance than did corresponding trait scales, but (c) both state and trait scales were dominated by stable trait-like variance. Follow-up bivariate latent state-trait analyses indicated that correlations between trait components of anger and anxiety correlated more strongly with trait components of caregiver–care recipient mutually communal behavior and care recipient problem behavior than did state–state component correlations. Implications for the measurement of state and trait components of psychological constructs are discussed.

Effectiveness of music therapy for alleviating pain during haemodialysis access cannulation for patients undergoing haemodialysis: a multi-facility, single-blind, randomised controlled trial

Background

Repeated pain during haemodialysis access cannulations is a serious problem for haemodialysis patients even when prescribed oral or topical analgesics. Although some studies have observed the efficacy of music therapy for improving pain and anxiety, its effectiveness during haemodialysis access cannulations during dialysis is uncertain. The purpose of this study is to investigate the effects of music therapy for pain when cannulating haemodialysis access for haemodialysis patients.

Methods

A prospective, multi-facility, single-blind, crossover, randomised controlled trial will be implemented. The intervention includes listening to Mozart, along with a white noise control condition. One hundred twenty haemodialysis patients will be enrolled across five facilities. Patients will be randomly allocated to either an Early-sequence group or a Later-sequence group. The Early-sequence group will receive cannulation while listening to Mozart’s Sonata for two pianos in D major (K.448) during the second week (Music period) and white noise during the fourth week (White noise period). The Later-sequence group will receive cannulation along with white noise first, followed by Mozart. All patients will also undergo cannulation during a no-sound period (wearing only headphones) during the first and third week (No-sound period). The music or no-music protocol will begin 8 min prior to the cannulating procedure, and participants will finish listening after starting haemodialysis during each period. The primary outcomes that will be assessed include the Visual Analogue Scale (VAS) score for pain during cannulation, and secondary outcomes are blood pressure, heart rate, VAS anxiety score, State-Trait Anxiety Inventory score, and salivary amylase activity. The operators who are in charge of haemodialysis access cannulation will be blind to the listening condition and VAS report.

Discussion

The proposed study has several methodological benefits. First, using white noise is a suitable control condition for addressing the role of sound in pain management. Additionally, using a crossover design with repeated measurements can help control individual differences between participants, which should better distinguish between- and within-participant variability. Overall, music therapy is a safe and inexpensive intervention that does not have the problematic side effects typically associated with pharmacological treatment. If effective, music therapy can be easily implemented for reducing pain and anxiety during cannulation.

Trial registration

This trial was prospectively registered to UMIN Clinical Trials Registry on 1 July 2018 (UMIN 000032850).

The Edinburgh Postpartum Depression Scale: Stable structure but subscale of limited value to detect anxiety

PURPOSE

The Edinburgh Postnatal Depression Scale (EPDS) aims at detecting postpartum depression. It has been hypothesized that a subscale (items 3, 4, 5) may detect anxiety. The aim of this study is to assess whether this EPDS anxiety subscale is present in a community-based dataset, and if so, to assess its validity and stability during the first six months postpartum.

METHODS

We obtained EPDS data of a community sample of 1612 women at 1 month, with follow-up at 3 and 6 months, postpartum (Post-Up study). We performed an exploratory factor analysis on the EPDS forcing two- and three-factor solutions. We assessed the correlations of the extracted factor subscales and the total EPDS with the short-form of the STAI (STAI-6). We examined the stability of the identified factors by means of a confirmatory factor analysis (CFA), using the EPDS data collected at 3 and 6 months postpartum.

RESULTS

Both the two- and three-factor solutions contained a hypothesized anxiety subscale of items 3,4,5,10, and fitted well with the 3- and 6-months EPDS data, with CFI and TLI values >.99 and RMSEA and SRMR values < .035 and < .45. The subscale's Pearson correlations with the STAI-6 were moderate: .516, compared to .643 for the total EPDS.

CONCLUSIONS

The factor structure of the EPDS is stable across the first six months postpartum, and includes the subscale assumed to represent anxiety. However, this subscale as well as the total EPDS correlate only moderately with anxiety criteria. Using the EPDS thus does not imply adequate screening for anxiety.

Brain structure changes induced by attention bias modification training

Attention bias modification (ABM) therapy aims to reduce anxiety by changing threat-related attention patterns using computerized training tasks. We examined changes in brain microstructure following ABM training. Thirty-two participants were randomly assigned to one of two training conditions: active ABM training shifting attention away from threat or attention control training involving no attention modification. Participants completed six lab visits, including five training sessions and three diffusion tensor imaging scans: immediately before and after the first training session, and at the end of the training series. Indices of local and global changes in microstructure and connectivity were measured. Significant longitudinal differences in fractional anisotropy (FA) between the active and control training regimens occurred in inferior temporal cortex. Changes in FA occurred across groups within ventromedial prefrontal cortex and middle occipital gyrus. These results indicate specific effects of active ABM on brain structure. Such changes could relate to clinical effects of ABM.

Bridging eating disorder symptoms and trait anxiety in patients with eating disorders: A network approach

OBJECTIVE

Anxiety is thought to influence the development and maintenance of eating disorders (EDs). However, little is known about how, specifically, anxiety influences ED symptoms and vice versa. Network analysis identifies how symptoms within and across disorders are interconnected. In a network, central nodes (i.e., symptoms) have the strongest relations to other nodes and are thought to maintain psychopathology. Bridge nodes are symptoms in one diagnostic cluster that are strongly connected to symptoms in another diagnostic cluster and are thought to explain comorbidity. We identified central and bridge nodes in a network of ED symptoms and trait anxiety features.

METHOD

We estimated a regularized partial correlation network in patients with mixed EDs (N = 296). ED symptoms were assessed with the Eating Disorder Examination-Questionnaire. Trait anxiety was assessed with the Trait subscale of the State-Trait Anxiety Inventory. Items to include in the network were selected with a statistical algorithm to ensure that all nodes represented unique constructs. Central and bridge nodes were identified with empirical calculations.

RESULTS

Central ED nodes were dietary restraint, as well as overvaluation of and dissatisfaction with shape and weight. The central trait anxiety node was low feelings of satisfaction. The strongest ED bridge node was avoidance of social eating. The strongest trait anxiety bridge node was low self-confidence.

DISCUSSION

Avoidance of social eating and low self-esteem may be routes through which EDs and trait anxiety are linked.

Longitudinal Postoperative Course of Pain and Dysfunction Following Total Knee Arthroplasty

OBJECTIVES

Although the majority of patients undergoing total knee arthroplasty (TKA) report substantial improvement in pain and function, a significant subset experience persistent postsurgical pain and dysfunction. Better understanding of the longitudinal postoperative course is needed, including the association between patient status following physical rehabilitation at 6-weeks post-TKA, to 6-months outcomes. This study aims to described the postoperative course of TKA and examine variables associated with change in pain and functioning between 6-weeks and 6-months post-TKA.

METHODS

In this longitudinal study of 223 participants, assessments of analgesic intake, depression, anxiety, pain catastrophizing, dysfunction, resting and range of motion pain, and pain sensitivity were completed at 6-weeks post-TKA. Analgesic intake, pain ratings, and dysfunction data were also collected at 6-months post-TKA. Pain and dysfunction ratings were divided into none-mild and moderate-severe categories.

RESULTS

Between 6-weeks and 6-months post-TKA, 75% of the sample stayed in the same pain category, 20% improved, and 5% worsened. In terms of functional changes between 6 weeks and 6 months, 65% of the sample stayed in the same functional category, whereas 31% improved and 5% worsened.

DISCUSSION

These findings demonstrate that the majority of patients' pain and functioning remains stable between 6 weeks and 6 months post-TKA. However, a notable subset continues to improve or worsen in pain and functioning and the current study identifies variables associated with these changes.

Implicitly and explicitly assessed anxiety: No relationships with recognition of and brain response to facial emotions

Trait anxiety, the disposition to experience anxiety, is known to facilitate perception of threats. Trait anxious individuals seem to identify threatening stimuli such as fearful facial expressions more accurately, especially when presented under temporal constraints. In past studies on anxiety and emotion face recognition, only self-report or explicit measures of anxiety have been administered. Implicit measures represent indirect tests allowing to circumvent problems associated with self-report. In our study, we made use of implicit in addition to explicit measures to investigate the relationships of trait anxiety with recognition of and brain response to emotional faces. 75 healthy young volunteers had to identify briefly presented (67 ms) fearful, angry, happy, and neutral facial expressions masked by neutral faces while undergoing functional magnetic resonance imaging. The Implicit Association Test, the State-Trait Anxiety Inventory and the Beck Anxiety Inventory were applied as implicit and explicit measures of trait anxiety. After corrections for multiple testing, neither implicitly nor explicitly measured anxiety correlated with recognition of emotional facial expressions. Moreover, implicitly and explicitly assessed anxiety was not linked to brain response to emotional faces. Our data suggest links between discrimination accuracy and brain response to facial emotions. Activation of the caudate nucleus seems be of particular importance for recognizing fear and happiness from facial expressions. Processes of somatosensory resonance appear to be involved in identifying fear from facial expressions. The present data indicate that, regardless of assessment method, trait anxiety does not affect the recognition of fear or other emotions as has been proposed previously.

Behavioral problems of preschool children with new-onset epilepsy and one-year follow-up - A prospective study

OBJECTIVES

Childhood emotional/behavioral problems in children with epilepsy have been reported to be higher compared with those with typical development or with other nonneurologic health conditions. Increasing interest towards understanding these behavioral comorbidities is reflected in literature. However, longitudinal investigations regarding the course of behavioral problems in children with newly diagnosed epilepsy and normal development are rare, and majority of them involve school-aged children. We aimed to study the behavioral comorbidities of preschool children with newly diagnosed epilepsy and to explore the changes of behavioral problems after one year from the diagnosis in comparison with the healthy group and subsequently, to elucidate the potential developmental, neurologic, and social risk factors associated with these difficulties.

METHODS

Participants were 83 patients, aged between 18 and 59 months, 43 of them were children with new-onset epilepsy, and 40 of them were healthy children as the comparison group. The Child Behavior Check List-1 1/2-5 (CBCL) was used to evaluate emotional/behavioral problems of the children. Maternal anxiety was analyzed by The State-Trait Anxiety Inventory (STAI). The general development of children was evaluated by the Denver-II-Developmental Screening Test (D-II-DST). Sociodemographic characteristics were also collected for all participants. Each evaluation was repeated after one year from the diagnosis.

RESULTS

Internalizing, externalizing, and total problem scores were higher in children with epilepsy than the control group at baseline, and despite some reduction in several scales, the differences continued across groups after one year. The analysis for the course revealed that behavior problem scores reduced in children with new-onset epilepsy over a year, but it did not change in healthy children. Among the possible factors related to behavior problem scores, in correlation analysis, the duration of screen viewing, socioeconomic status, and maternal education were associated with behavior problem scores. There was no significant association between epilepsy-related variables and the behavior problem scores and the course. Among all possible risk factors in the regression analyses, maternal trait anxiety level was found to be significantly related to the total problems, internalizing, and externalizing scores in the group with epilepsy.

CONCLUSION

Behavioral comorbidities of epilepsy are present very early and can be seen at the time of the diagnosis, however, they do not worsen over time in preschool children. Maternal anxiety should be considered as a risk factor for behavioral problems in preschool children with epilepsy. Assisting children and parents and ensuring necessary guidance and support should be a crucial part of epilepsy treatment initiated as soon as the time of diagnosis.

Default mode network alterations in individuals with high-trait-anxiety: An EEG functional connectivity study

BACKGROUND

Although several researches investigated Default Mode Network (DMN) alterations in individuals with anxiety disorders, up to now no studies have investigated DMN functional connectivity in non-clinical individuals with high-trait-anxiety using quantitative electroencephalography (EEG). Here, the main aim was to extend previous findings investigating the association between trait anxiety and DMN EEG functional connectivity.

METHODS

Twenty-three individuals with high-trait-anxiety and twenty-four controls were enrolled. EEG was recorded during 5 min of resting state (RS). EEG analyses were conducted by means of the exact Low-Resolution Electromagnetic Tomography software (eLORETA).

RESULTS

Compared to controls, individuals with high-trait-anxiety showed a decrease of theta connectivity between right medial prefrontal cortex (mPFC) and right posterior cingulate/retrosplenial cortex. A decrease of beta connectivity was also observed between right mPFC and right anterior cingulate cortex. Furthermore, DMN functional connectivity strength was negatively related with STAI-T total score (i.e., lower connectivity was associated with higher trait anxiety), even when controlling for potential confounding variables (i.e., sex, age, and general psychopathology).

LIMITATIONS

Small sample size makes it difficult to draw definitive conclusions. Furthermore, we did not assess state variation of anxiety, which make our interpretation specific to trait anxiety.

CONCLUSIONS

Taken together, our results suggest that high-trait-anxiety individuals fail to synchronize DMN during RS, reflecting a possible top-down cognitive control deficit. These results may help in the understanding of the individual differences in functional brain networks associated with trait anxiety, a crucial aim in the prevention and in the early etiology understanding of clinical anxiety and related sequelae.

Dimensions of Anxiety, Age, and Gender: Assessing Dimensionality and Measurement Invariance of the State-Trait for Cognitive and Somatic Anxiety (STICSA) in an Italian Sample

The State-Trait Inventory for Cognitive and Somatic Anxiety (STICSA) is a widely used measure of state and trait anxiety that permits a specific assessment of cognitive and somatic anxiety. Previous research provided inconsistent findings about its factor structure in non-clinical samples (e.g., hierarchical or bi-factor structure). To date, no psychometric validation of the Italian version of the STICSA has been conducted. Our study aimed to determine the psychometric functioning of the Italian version of the STICSA, including its dimensionality, gender and age measurement equivalence, and convergent/divergent validity in a large sample of community-dwelling participants (N = 2,938; 55.9% female). Through confirmatory factor analysis, the multidimensional structure of both State and Trait STICSA scales, with each including Cognitive and Somatic dimensions, was supported. Factor structure invariance was tested and established at configural, metric, and scalar levels for males and females. Additionally, full factorial measurement invariance was supported for the State scale across young, middle age, and old adult groups whereas the Trait scale was partially invariant across age groups. The STICSA also showed good convergent validity with concurrent anxiety measures (State-Trait Anxiety Inventory and Beck Anxiety Inventory), and satisfactory internal discriminant validity with two depression measures (Teate Depression Inventory and Beck Depression Inventory-II). Results provided support for the multidimensionality of the STICSA, as well as the generalizability of the State and Trait scales as independent measures of Cognitive and Somatic symptomatology across gender in the general population. Implications for research and personality and clinical assessment are discussed.

Characteristics Associated With Physical Function Trajectories in Older Adults With Cancer During Chemotherapy

CONTEXT

Studies on physical function trajectories in older adults during chemotherapy remain limited.

OBJECTIVES

The objective of this study was to determine demographic, clinical, and symptom characteristics associated with initial levels as well as trajectories of physical function over two cycles of chemotherapy in adults aged ≥65 years with breast, gastrointestinal, gynecological, or lung cancer.

METHODS

Older adults with cancer (n = 363) who had received chemotherapy within the preceding four weeks were assessed six times over two cycles of chemotherapy using the Short Form-12 Physical Component Summary (PCS) score. Hierarchical linear modeling was used to evaluate for interindividual variability in initial levels and trajectories of PCS scores.

RESULTS

Mean age was 71.4 years (SD 5.5). Mean PCS score at enrollment was 40.5 (SD .45). On average, PCS scores decreased slightly (i.e., 0.21 points) at each subsequent assessment. Lower PCS scores at enrollment were associated with older age, greater comorbidity, being unemployed, lack of regular exercise, higher morning fatigue, lower evening energy, occurrence of pain, lower trait anxiety, and lower attentional function. Only higher morning fatigue and lower enrollment PCS scores were associated with decrements in physical function over time.

CONCLUSION

While several symptoms were associated with decrements in PCS scores at enrollment in older adults with cancer receiving chemotherapy, morning fatigue was the only symptom associated with decreases in physical function over time. Regular assessments of symptoms and implementation of evidence-based interventions should be considered to maintain physical function in older adults during chemotherapy.
