Cognitive content specificity in anxiety and depressive disorder symptoms: a twin study of cross-sectional associations with anxiety sensitivity dimensions across development

Associations between disordered eating, internalizing symptoms, and behavioral and neural correlates of response inhibition in preadolescence

Response inhibition difficulties are reported in individuals with eating disorders (EDs), anxiety, and depression. Although ED symptoms and internalizing symptoms co-occur in preadolescence, there is limited research examining associations between these symptoms and response inhibition in this age group. This study is the first to investigate the associations between behavioral and neural markers of response inhibition, disordered eating (DE), and internalizing symptoms in a community sample of preadolescents. Forty-eight children (M age = 10.95 years, 56.3% male) completed a Go/NoGo task, whereas electroencephalography was recorded. Self-report measures of DE and internalizing symptoms were collected. Higher levels of anxiety and depression were associated with neural markers of suboptimal response inhibition (attenuated P3NoGo amplitudes) in preadolescence. In contrast, higher levels of depression were associated with greater response inhibition at a behavioral level. These findings suggest internalizing symptoms in preadolescence are associated with P3-indexed difficulties in evaluation and monitoring, but these are not sufficient to disrupt behavioral performance on a response inhibition task. This pattern may reflect engagement of compensatory processes to support task performance. DE was not significantly associated with response inhibition, suggesting that difficulties in response inhibition may only be reliably observed in more chronic and severe DE and ED presentations.

Evidence for distinct genetic and environmental influences on fear acquisition and extinction

BACKGROUND

Anxiety disorders are highly prevalent with an early age of onset. Understanding the aetiology of disorder emergence and recovery is important for establishing preventative measures and optimising treatment. Experimental approaches can serve as a useful model for disorder and recovery relevant processes. One such model is fear conditioning. We conducted a remote fear conditioning paradigm in monozygotic and dizygotic twins to determine the degree and extent of overlap between genetic and environmental influences on fear acquisition and extinction.

METHODS

In total, 1937 twins aged 22-25 years, including 538 complete pairs from the Twins Early Development Study took part in a fear conditioning experiment delivered remotely via the Fear Learning and Anxiety Response (FLARe) smartphone app. In the fear acquisition phase, participants were exposed to two neutral shape stimuli, one of which was repeatedly paired with a loud aversive noise, while the other was never paired with anything aversive. In the extinction phase, the shapes were repeatedly presented again, this time without the aversive noise. Outcomes were participant ratings of how much they expected the aversive noise to occur when they saw either shape, throughout each phase.

RESULTS

Twin analyses indicated a significant contribution of genetic effects to the initial acquisition and consolidation of fear, and the extinction of fear (15, 30 and 15%, respectively) with the remainder of variance due to the non-shared environment. Multivariate analyses revealed that the development of fear and fear extinction show moderate genetic overlap (genetic correlations 0.4-0.5).

CONCLUSIONS

Fear acquisition and extinction are heritable, and share some, but not all of the same genetic influences.

Relations between anxiety sensitivity's cognitive concerns and anxiety severity: brooding and reflection as serial multiple mediators

The outbreak of COVID-19 has caused a major impact on productivity and life functioning, and also led to adverse emotional reactions. In the face of this public health event, increased anxiety is one of the most common emotional reactions. Previous studies have shown that anxiety sensitivity, rumination and anxiety are closely related. Various dimensions of anxiety sensitivity have different effects on anxiety. Also, rumination can be divided into brooding and reflection. To explore the relationships among anxiety sensitivity's cognitive concerns, anxiety and different types of rumination, we conducted an online survey during the outbreak of coronavirus (February 17-25, 2020), using the Anxiety Sensitivity Scale-3 (ASI-3), Ruminative Responses Scale (RSS), and Depression Anxiety Stress Scale-21 (DASS-21). The results showed significant positive correlations among anxiety sensitivity's cognitive concerns, anxiety, brooding and reflection. Furthermore, brooding and reflection had a chain mediation effect between cognitive concerns and anxiety, and the mediation effect of reflection was even stronger. Results suggest that anxiety sensitivity's cognitive concerns may not only affect anxiety directly, but also affect anxiety through rumination, especially reflection.

Disordered eating and internalizing symptoms in preadolescence

OBJECTIVES

Research has demonstrated links between disordered eating, anxiety, and depression in adults and adolescents but there is limited research investigating these associations in preadolescence. The current study examined the associations between disordered eating, anxiety, and depression during preadolescence, as well as the role of gender in moderating these associations.

METHOD

Two hundred and thirteen children (M = 10.3 years; 51.2% male) reported levels of disordered eating (ChEAT) and anxiety and depression symptoms (RCADS-25).

RESULTS

Regression analyses support an association between disordered eating and both anxiety and depression in preadolescence. Overall, there were no significant differences between boys and girls when the main effect was examined, which differs from research in adolescents.

DISCUSSION

These findings highlight the importance of early detection for disordered eating behaviors and attitudes, as well as anxiety and depression in both boys and girls during preadolescence. Longitudinal research examining these associations is vital to help understand the trajectories of these problems, but also the gender differences in disordered eating that emerge during adolescence. Transdiagnostic interventions targeting several co-occurring problems, such as disordered eating, anxiety, and depression might be effective for preventing the development of eating disorders in the long term.

Anxiety sensitivity and bodily kinematics

Anxiety sensitivity (AS) is an individual difference factor reflecting the fear of anxiety-related sensations and is one of the best researched risk factors for psychopathology. Decades of research have focused on exploring the relations between AS and clinical symptoms and disorders, although most of the research has employed self-report or interview-based methodologies to index primary dependent measures. No past research has sought to characterize the explanatory relevance of AS from a body kinematics perspective. The present study explored AS in relation to body kinematics to AS-specific images using a dual-task attentional control paradigm (i.e., approach versus avoidance) that employs AS-specific stimuli and motion-tracking technology. Participants included 108 young adults (58.3% female, M age = 25.3) who took part in a ball catching game to index their measures of behavioral engagement with the AS-specific and neutral stimuli presented at either side of the game environment. After adjusting for age, gender, race, handedness, physical functioning, and negative affectivity, self-reported AS was significantly associated with biokinematically-driven behavioral engagement with the AS-specific stimuli. The present study provides novel empirical evidence that AS is related to anxiety-related bodily kinematics. Future work is needed to extend the current results to clinical samples.

A pilot study of attachment relationships, psychological problems and negative automatic thoughts among college students in Pakistan

Objectives The present pilot study examined the associations between attachment relationships, psychological problems, and negative automatic thoughts among late adolescents in Rawalpindi, Pakistan. Subjects A total of 98 participants (male = 49, female = 49) were recruited from government colleges in Rawalpindi, Pakistan. Methods The measures used to assess the research variables of this cross sectional study were the Inventory of Parent-Peer Attachment (IPPA-Urdu), Depression, Anxiety, and Stress Scale (DASS-Urdu), and the Automatic Thought Questionnaire (ATQ-Urdu). Results All of these measures had good reliabilities. Findings of the correlation analyses demonstrated that maternal, paternal and peer attachment relationships were negatively related to symptoms of depression and anxiety as well as to negative automatic thoughts. On the other hand, depressive and anxiety symptoms were positively associated with negative automatic thoughts. Additionally, findings suggested that future studies must investigate adolescents from two-parent households and exclude those with only one living parent. Conclusion The results underscored the need for further investigations of the linkages between attachment relationships, negative automatic thoughts and psychological problems on larger samples.

Mindfulness and associations with symptoms of insomnia, anxiety and depression in early adulthood: A twin and sibling study

This study investigated associations between mindfulness and symptoms of insomnia, depression and anxiety. Mindfulness was disaggregated into five subscales: 'nonreactivity to inner experience', 'observing', 'acting with awareness', 'describing' and 'nonjudging of inner experience'. Twin models were used to examine genetic and environmental influences on mindfulness, symptoms of insomnia, depression and anxiety and on their associations. Data came from a longitudinal twin/sibling study (G1219) comprising 862 individuals (age range 22-32 years, 66% females). Less mindfulness was associated with greater symptoms of insomnia, depression and anxiety (r = .22-.48). Of the mindfulness subscales, 'nonjudging of inner experience' was most strongly associated with the other traits. Overall mindfulness was largely influenced by non-shared environmental factors (E = .72) although familial influences played a role for overall mindfulness, as well as for the 'acting with awareness' and 'describing' subscales. The genetic correlations between overall mindfulness and symptoms of insomnia, depression and anxiety ranged from .32 to .75 (but were non-significant), while the shared environmental correlations ranged from -.78 to .79 (also non-significant). The non-shared environmental influences between these three variables were moderately, significantly correlated (rE = .21-.55).

Cognitive factors associated with depression and anxiety in adolescents: A two-year longitudinal study

Background/Objective: To examine the roles of anxiety sensitivity and attentional bias in the development of anxiety and depression symptoms among adolescents. Method: 214 grade 7 to grade 10 Hong Kong Chinese students completed a package of psychometric inventories to measure levels of anxiety sensitivity, selective attentional processing, and anxiety and depressive symptoms in 2016 and then again in 2017. Results: Girls, when compared with boys, exhibited more anxiety symptoms and anxiety sensitivity in 2016. They also reported a significant increase in mean depression level from 2016 to 2017. Regression analyses revealed that the physical-concerns dimension of anxiety sensitivity, positive attentional bias, and to a lesser extent negative attentional bias were related to the development of both anxiety and depression symptoms one year later. Fear of mental incapacity could predict depression one year later but not anxiety symptoms. Conclusions: Intervention through anxiety sensitivity training to reduce somatic concerns and attentional bias modification to increase habitual attention to positive stimuli and to disengage from negative stimuli can reduce anxiety and depression symptoms among high school students.

The Contribution of Anxiety Sensitivity to Obsessive-Compulsive and Anxiety Symptoms in a Naturalistic Treatment Setting

Anxiety sensitivity, a fear of arousal-related sensations, is prevalent in a number of disorders. We examined the relationship between internalizing symptoms and the anxiety sensitivity components of physical, social, and cognitive concerns in a sample of 165 patients seeking treatment in a clinic specializing in CBT for anxiety-related disorders. Social anxiety symptoms were associated with greater social concerns. Cognitive concerns were characteristic of both depression and generalized anxiety symptoms, suggesting these two classes of symptoms may share AS symptomatology. Physical concerns were specifically related to panic symptoms. Although obsessive-compulsive symptoms were related to cognitive concerns using univariate regression, these symptoms were not strongly related to any of the anxiety sensitivity components when the correlation between disorders was taken into account. Thus, within the internalizing symptoms studied here, the anxiety sensitivity domains were most relevant to panic, social anxiety, generalized anxiety, and depressive symptoms and less related to obsessive-compulsive symptoms.

The effect of positive and negative memory bias on anxiety and depression symptoms among adolescents

OBJECTIVE

To examine the interaction effect of anxiety and depression on the intentional forgetting of positive and negative valence words.

METHODS

One hundred fifty-five grade 7 to grade 10 students participated in the study. The item-method directed forgetting paradigm was used to examine the intentional forgetting of positive-valence, negative-valence, and neutral-valence words.

RESULTS

Negative-valence words were recognized better than either positive-valence or neutral-valence words. The results revealed an anxiety main effect (p = .01, LLCI = -.09, and ULCI = -.01) and a depression main effect (p = .04, LLCI = .00, and ULCI = .24). The anxiety score was negative, whereas the depression score was positively related to the directed forgetting of negative-valence words. Regression-based moderation analysis revealed a significant anxiety × depression interaction effect on the directed forgetting of positive-valence words (p = .02, LLCI = .00, and ULCI = .01). Greater anxiety was associated with more directed forgetting of positive-valance words only among participants with high depression scores. With negative-valence words, the anxiety × depression interaction effect was not significant (p = .15, LLCI = - .00, and ULCI = .01).

CONCLUSION

Therapeutic strategies to increase positive memory bias may reduce anxiety symptoms only among those with high depression scores. Interventions to reduce negative memory bias may reduce anxiety symptoms irrespective of levels of depression.

A longitudinal twin and sibling study of the hopelessness theory of depression in adolescence and young adulthood

BACKGROUND

Maladaptive cognitive biases such as negative attributional style and hopelessness have been implicated in the development and maintenance of depression. According to the hopelessness theory of depression, hopelessness mediates the association between attributional style and depression. The aetiological processes underpinning this influential theory remain unknown. The current study investigated genetic and environmental influences on hopelessness and its concurrent and longitudinal associations with attributional style and depression across adolescence and emerging adulthood. Furthermore, given high co-morbidity between depression and anxiety, the study investigated whether these maladaptive cognitions constitute transdiagnostic cognitive content common to both internalizing symptoms.

METHOD

A total of 2619 twins/siblings reported attributional style (mean age 15 and 17 years), hopelessness (mean age 17 years), and depression and anxiety symptoms (mean age 17 and 20 years).

RESULTS

Partial correlations revealed that attributional style and hopelessness were uniquely associated with depression but not anxiety symptoms. Hopelessness partially mediated the relationship between attributional style and depression. Hopelessness was moderately heritable (A = 0.37, 95% confidence interval 0.28-0.47), with remaining variance accounted for by non-shared environmental influences. Independent pathway models indicated that a set of common genetic influences largely accounted for the association between attributional style, hopelessness and depression symptoms, both concurrently and across development.

CONCLUSIONS

The results provide novel evidence that associations between attributional style, hopelessness and depression symptoms are largely due to shared genetic liability, suggesting developmentally stable biological pathways underpinning the hopelessness theory of depression. Both attributional style and hopelessness constituted unique cognitive content in depression. The results inform molecular genetics research and cognitive treatment approaches.

Risk factors for comorbid psychopathology in youth with psychogenic nonepileptic seizures

PURPOSE

To examine the risk factors for internalizing (anxiety, depression) and posttraumatic stress (PTSD) disorders, somatization, and anxiety sensitivity (AS) in youth with psychogenic non-epileptic seizures (PNES).

METHODS

55 probands with PNES and 35 siblings, aged 8-18 years, underwent a psychiatric interview, cognitive and language testing, and completed somatization and AS questionnaires. Parents provided the subjects' medical, psychiatric, family, and adversity history information.

RESULTS

The risk factors for the probands' internalizing disorders (girls, older age of PNES onset), somatization (older age, epilepsy), and anxiety sensitivity (girls, adversities) differed from their siblings. The risk factors in the siblings, however, were similar to the general pediatric population. Proband depression was unrelated to the study's risk variables while PTSD was significantly associated with female gender and lower Full Scale IQ.

CONCLUSIONS

Knowledge about the specificity of the risk factors for comorbid psychopathology in youth with PNES might facilitate their early identification and treatment.

Assessing Negative Automatic Thoughts: Psychometric Properties of the Turkish Version of the Cognition Checklist

Background:

Beck’s theory of emotional disorder suggests that negative automatic thoughts (NATs) and the underlying schemata affect one’s way of interpreting situations and result in maladaptive coping strategies. Depending on their content and meaning, NATs are associated with specific emotions, and since they are usually quite brief, patients are often more aware of the emotion they feel. This relationship between cognition and emotion, therefore, is thought to form the background of the cognitive content specificity hypothesis. Researchers focusing on this hypothesis have suggested that instruments like the cognition checklist (CCL) might be an alternative to make a diagnostic distinction between depression and anxiety.

Objectives:

The aim of the present study was to assess the psychometric properties of the Turkish version of the CCL in a psychiatric outpatient sample.

Patients and Methods:

A total of 425 psychiatric outpatients 18 years of age and older were recruited. After a structured diagnostic interview, the participants completed the hospital anxiety depression scale (HADS), the automatic thoughts questionnaire (ATQ), and the CCL. An exploratory factor analysis was performed, followed by an oblique rotation. The internal consistency, test-retest reliability, and concurrent and discriminant validity analyses were undertaken.

Results:

The internal consistency of the CCL was excellent (Cronbach’s α = 0.95). The test-retest correlation coefficients were satisfactory (r = 0.80, P < 0.001 for CCL-D, and r = 0.79, P < 0.001 for CCL-A). The exploratory factor analysis revealed that a two-factor solution best fit the data. This bidimensional factor structure explained 51.27 % of the variance of the scale. The first factor consisted of items related to anxious cognitions, and the second factor of depressive cognitions. The CCL subscales significantly correlated with the ATQ (rs 0.44 for the CCL-D, and 0.32 for the CCL-A) as well as the other measures of mood severity (all Ps < 0.01). To a great extent, all items of the CCL were able to distinguish the clinical and non-clinical groups, suggesting the scale has high discriminating validity.

Conclusions:

The current study has provided evidence that the Turkish version of the CCL is a reliable and valid instrument to assess NATs in a clinical outpatient sample.

Changes in Cognitive Errors Over the Course of Cognitive Therapy for Depression

Cognitive therapy (CT) aims to treat major depression symptomatology by restructuring the patients' cognitive distortions to more adaptive thinking patterns. This study examined changes in cognitive errors (CEs) as patients undergo CT for depression. Forty-five participants were assessed at early and late therapy for CEs using the Cognitive Errors Rating System (Drapeau, Perry, & Dunkley, 2008) and for depression using the Beck Depression Inventory (A. T. Beck, Rush, Shaw, & Emery, 1979). Although the total number of CEs did not change from early to late therapy, negative CEs significantly decreased, and positive CEs increased. Recovered participants had fewer total CEs, negative CEs, and negative overgeneralization than nonrecovered participants. Depressive symptoms were inversely related to late therapy positive CEs among the nonrecovered participants. Research and clinical implications are discussed.

A multivariate twin study of trait mindfulness, depressive symptoms, and anxiety sensitivity

BACKGROUND

Mindfulness-based therapies have been shown to be effective in treating depression and reducing cognitive biases. Anxiety sensitivity is one cognitive bias that may play a role in the association between mindfulness and depressive symptoms. It refers to an enhanced sensitivity toward symptoms of anxiety, with a belief that these are harmful. Currently, little is known about the mechanisms underpinning the association between mindfulness, depression, and anxiety sensitivity. The aim of this study was to examine the role of genetic and environmental factors in trait mindfulness, and its genetic and environmental overlap with depressive symptoms and anxiety sensitivity.

METHODS

Over 2,100 16-year-old twins from a population-based study rated their mindfulness, depressive symptoms, and anxiety sensitivity.

RESULTS

Twin modeling analyses revealed that mindfulness is 32% heritable and 66% due to nonshared environmental factors, with no significant influence of shared environment. Genetic influences explained over half of the moderate phenotypic associations between low mindfulness, depressive symptoms, and anxiety sensitivity. About two-thirds of genetic influences and almost all nonshared environmental influences on mindfulness were independent of depression and anxiety sensitivity.

CONCLUSIONS

This is the first study to show that both genes and environment play an important role in the etiology of mindfulness in adolescence. Future research should identify the specific environmental factors that influence trait mindfulness during development to inform targeted treatment and resilience interventions. Shared genetic liability underpinning the co-occurrence of low mindfulness, depression, and anxiety sensitivity suggests that the biological pathways shared between these traits should also be examined.

Cognitive Vulnerabilities for Depression and Anxiety in Childhood: Specificity of Anxiety Sensitivity and Rumination

Background: Childhood anxiety and depression frequently co-occur. Exploring specificity in cognitive processes for anxiety and depression in childhood can provide insight into cognitive vulnerabilities contributing to the development of anxiety and depressive disorders and inform targeted psychological interventions. Anxiety sensitivity and rumination are robust cognitive vulnerabilities for anxiety and depression, respectively. However, despite conceptual similarities, they are rarely considered together within a single study. Aims: The current study explored specific and shared associations between anxiety sensitivity subscales and rumination and anxiety and depressive symptoms in unselected children. Method: Multiple regression analyses explored to what extent specific self-reported anxiety sensitivity subscales (physical, social and mental concerns) and rumination predicted anxiety and depressive symptoms in 147 unselected children, aged 7–11 years. Results: Physical and social concern subscales of anxiety sensitivity were specifically associated with anxiety, whilst rumination was specifically associated with depressive symptoms. The mental concerns subscale of anxiety sensitivity was independently associated with both anxiety and depressive symptoms. These associations were only partially mediated by rumination. Conclusions: Anxiety and depression in young people are characterized by specific and shared cognitions. Evidence for shared and specific associations between the cognitive vulnerabilities of anxiety sensitivity and rumination, and anxiety and depression highlight the utility of transdiagnostic research and confirm that cognitive therapies may benefit from targeting cognitive concerns relating specifically to the patient's presenting symptoms.
