Given that emotion regulation difficulties confer risk for poor responses to stress, they may predict who is at risk for adverse psychological reactions to major, chronic stressors such as the COVID-19 pandemic. Specific adverse reactions to the pandemic may include more severe traumatic stress, anxiety, and excessive safety behavior use (i.e., hand washing). While emotion regulation difficulties may be a diathesis for adverse reactions to chronic stressors, the context(s) by which they may confer elevated risk is unclear. Accordingly, the present longitudinal study examined the interaction between pre-pandemic emotion regulation difficulties and early pandemic perceived stress in predicting subsequent COVID-related traumatic stress, anxiety, and safety behavior use over 32 weeks of the pandemic. Community adults (N = 145) who completed a measure of emotion regulation in 2016 as part of a larger study were recontacted at the start of the pandemic (March 2020) and assessed every two weeks for 32 weeks. Consistent with a diathesis-stress model, the interaction between difficulties in emotion regulation and perceived stress was significant in predicting COVID-19 anxiety (p = 0.003, d = 0.52) such that at high, but not low, levels of perceived stress, difficulties in emotion regulation in 2016 significantly predicted higher COVID-19 anxiety in 2020. The interaction between difficulties in emotion regulation in 2016 and perceived stress early in 2020 approached significance in predicting COVID-19 traumatic stress (p = 0.073, d = 0.31) and safety behavior use (p = 0.069, d = 0.31). These findings highlight that current perceived stress is an important context that potentiates the effects of preexisting emotion regulation difficulties on the emergence of anxiety-related symptoms during COVID-19, which has important implications for diathesis-stress models of adverse reactions to chronic stressors.

Emotion dysregulation (ED) is a vulnerability factor for affective disorders that may originate from deficits in cognitive control (CC). Although measures of ED are often designed to assess trait-like tendencies, the extent to which such measures capture a time-varying (TV) or state-like construct versus a time-invariant (TI) or trait-like personality characteristic is unclear. The link between the TV and TI components of ED and CC is also unclear. In a 6-wave, 5-month longitudinal study, community participants (n = 1281) completed the Difficulties in Emotion Regulation Scale (DERS-16), a commonly used measure of ED and measures of CC. A latent variable (trait-state-occasion) model showed that the proportion of TI factor variance (.80) was greater than the TV factor variance (.19). Although TV factor stability was significant, the coefficients were small in magnitude. Furthermore, regression weights for the ED TI factor (average ß = -.62) were significant and larger than those for the TV factor (average ß = -.10) in predicting latent CC at each of the six-time points. These findings suggest that ED, as assessed by the DERS-16, is largely TI and this TI component is more strongly linked to CC than the TV component.

Disgust can be acquired via evaluative conditioning; a process by which a neutral stimulus (conditioned stimulus; CS) comes to be evaluated as disgusting due to its pairing with an inherently disgusting stimulus (unconditioned stimulus; US). Research has shown that conditioned disgust responses are resistant to extinction which may have implications for disorders (i.e., contamination-based obsessive-compulsive disorder, specific phobias, and post-traumatic stress disorder) in which heightened disgust has been implicated. Importantly, extinction is the primary mechanism by which exposure therapies are thought to achieve symptom reduction for these disorders. Exposure therapies were originally modeled on fear extinction, whereas disgust extinction was largely overlooked until recently. Accordingly, differences in the degree to which learned disgust and fear can be attenuated via extinction learning remains unclear. The present investigation was a meta-analysis directly comparing the degree of extinction of conditioned disgust (n = 14) and conditioned fear (n = 14) in laboratory paradigms. Extinction was operationalized as the standardized mean difference (SMD) in evaluative ratings between the CS+ (the CS paired with the US) and CS- (the unpaired CS) after extinction training. Results of a subgroup analysis indicated that disgust (SMD = 0.52) was significantly more resistant to extinction than fear (SMD = 0.37). Additionally, a series of meta-regression analyses indicated that extinction was not influenced by important study characteristics (e.g., sex, age, number of conditioning and extinction trials). The findings suggest that extinction-based approaches may be less effective at attenuating learned disgust and research is needed to better optimize treatments for disgust-related disorders.

The COVID-19 pandemic precipitated an uptick in poor mental health outcomes, including coronavirus-related anxiety and distress. Preliminary research has shown that intolerance of uncertainty (IU) and worry proneness, two transdiagnostic risk factors for anxiety and related disorders, are associated cross-sectionally with pandemic-related fear and distress. However, the extent to which IU and worry proneness prospectively predict coronavirus-related anxiety and distress is unclear. Whether IU and worry may also interact in prospectively predicting coronavirus-related anxiety and distress is also unknown. To address this knowledge gap, the present study examined IU and trait worry as prospective predictors of the level and trajectory of coronavirus anxiety and COVID stress syndrome over time, as well as the extent to which worry moderated the relation between IU and pandemic-related outcomes. Participants (n = 310) who completed self-report measures of IU and trait worry in 2016 were contacted following the onset of COVID-19 in 2020 and completed biweekly measures of coronavirus anxiety and COVID stress syndrome for 30 weeks. Multilevel models revealed that IU assessed in 2016 significantly predicted the severity of both coronavirus anxiety and COVID stress syndrome throughout the study period in 2020. Worry also moderated the link between IU and coronavirus anxiety, such that individuals with high levels of trait worry and high IU in 2016 experienced the most coronavirus anxiety in 2020. Results suggest that IU and worry functioned as independent and interactive vulnerability factors for subsequent adverse psychological reactions to COVID-19. Clinical implications and future directions are discussed.

BACKGROUND: Worry is a transdiagnostic risk factor for stress-related mental health complaints such as anxiety, depression, and insomnia. Although worry may function as a form of avoidance of unwanted emotions and accordingly interfere with adaptive emotion regulation, the specific domains of emotion regulation that are perturbed by excessive worry to confer risk for stress-related symptoms are unclear. Further, it is unknown if cognitive control mechanisms that underlie successful emotion regulation influence the effect of worry on stress. The present study addressed these gaps in the literature by examining specific emotion regulation difficulties as mediators of the relationship between worry and subsequent stress, as well as executive function as a moderator of the mediated effects. METHOD: 656 community adults were assessed for trait worry, emotion dysregulation, stress, and executive dysfunction once per month for three months (time 1 - time 3). RESULTS: The effect of worry (time 1) on subsequent stress (time 3) was partially mediated by difficulties with emotional clarity and difficulty engaging in goal-directed behavior when upset (time 2) after controlling for age, gender, and baseline stress. Moderated mediation models revealed that the indirect effect of worry on stress via difficulty with goal-directed behavior was significantly moderated by executive dysfunction, such that fewer executive function difficulties acted as a buffer against the harmful effects of worry. LIMITATIONS: Limitations include reliance on self-report measures, lack of experimental manipulation, and a nonclinical sample. CONCLUSIONS: Findings point to specific domains of emotion regulation as treatment targets for individuals with high worry proneness.

This commentary addresses the thought-provoking article by Lorenzo-Luaces (in press). We review areas of both agreement and disagreement with the author's points, noting that readers should not infer that research into active ingredients and mechanisms is pointless. We conclude with a call for more research into the mechanisms of therapeutic change and the active ingredients of therapeutic interventions, with the aim of disseminating treatments that are both effective and efficient.

Despite growing interest in ecological momentary assessment (EMA) in psychopathology and clinical observation of day-to-day fluctuations in obsessive-compulsive disorder (OCD) symptoms, there is not a standardized EMA measure of such symptoms that can guide systematic research. In the absence of such a measure, prior EMA research in OCD has utilized heterogeneous approaches to sampling momentary and daily OCD symptoms, which limits the ability to compare results between studies. The present study sought to examine the psychometric properties of a daily OCD symptom (d-OCS) measure that assesses common OCD symptom themes (e.g., contamination, checking, intrusive thoughts) in a sample of adults with OCD (n = 20), psychiatric controls (n = 27), and healthy controls (n = 27). Participants completed the d-OCS 3 times per day for 1 week. The d-OCS distinguished those with OCD from psychiatric controls and healthy controls. The d-OCS demonstrated good internal consistency, adequate test-retest reliability, and good convergent validity. These findings offer initial psychometric support for the use of the d-OCS in EMA research examining day-to-day fluctuations in symptoms of OCD. Additional investigation is needed to examine the discriminant validity of the d-OCS and generalize these findings to more diverse samples.

Although conditioning approaches have highlighted potential characteristics of disgust in anxiety disorders, obsessive-compulsive disorder (OCD), and posttraumatic stress disorder (PTSD), these findings have yet to be translated into evidence-based treatments. Examination of the literature suggests various indicators of disgust that predict treatment outcome in these disorders. However, mechanisms remain unclear because studies examining disgust during the course of treatment are limited. Increasingly, the field has moved toward experimental investigation of strategies that reduce disgust. While cognitive reappraisal and imagery techniques appear promising, such techniques have yet to be examined as anxiety disorder treatments in large-scale randomized clinical trials. The literature also points to novel approaches to treating disgust, ranging from an inhibitory-informed approach to exposure therapy to transcranial direct current stimulation. However, the development of novel treatment approaches will require more rigorous experimental psychopathology approaches that can further elucidate processes that contribute to the etiology and/or maintenance of disorders of disgust.

Prior work implicates sleep disturbance in the development and maintenance of posttraumatic stress disorder (PTSD). However, the majority of this literature has focused on combat veteran men, and limited work has examined links between sleep disturbance and PTSD symptoms in sexual assault survivors. This is a notable gap in the literature, as sexual trauma is disproportionately likely to result in PTSD and is more common in women. We sought to examine the relations between subjective sleep disturbance, sexual assault severity, and PTSD symptoms in a sample of sexual assault survivors with PTSD (PTSD+), without PTSD (PTSD-), and healthy controls. The sample (N = 60) completed the Insomnia Severity Index and prospectively monitored their sleep for 1 week using the Consensus Sleep Diary. The sexual assault survivors also completed the Sexual Experiences Survey and PTSD Checklist-5. Results of group comparisons found that the PTSD+ group reported significantly higher insomnia symptoms, longer sleep onset latency, more nocturnal awakenings, and lower sleep quality compared to the healthy control group and higher insomnia symptoms compared to the PTSD- group. Results of regression analyses in the sexual assault survivors found that insomnia symptoms and number of nocturnal awakenings were significantly associated with higher PTSD symptoms, and sexual assault severity was significantly associated with higher insomnia symptoms, longer sleep onset latency, and lower sleep quality. These findings highlight specific features of sleep disturbance that are linked to trauma and PTSD symptom severity among sexual assault survivors.

Sleep disturbance is highly debilitating, and an abundance of research suggests that repetitive negative thinking (i.e., rumination, worry) may contribute to the development and maintenance of maladaptive sleep patterns, such as insomnia symptoms. Although repetitive negative thinking is often conceptualized as a 'trait' risk factor for anxiety-related disorders, it is unclear if it consists of time-varying (TV) or state-like features versus time-invariant (TI) or trait-like characteristics. Furthermore, it is unclear if it is the TV or TI components of repetitive negative thinking that contribute to insomnia symptoms that is commonly observed in anxiety-related disorders. In a 6-wave, 5-month longitudinal study, community participants (N = 1219) completed measures of rumination, worry, transdiagnostic repetitive negative thinking, and insomnia symptoms. A latent variable (trait-state-occasion) model was applied to the measures of repetitive negative thinking. The results showed that although estimates of TI factor variance and TV factor variance were both significant for latent repetitive negative thinking, worry, and rumination, the proportion of TI factor variance (0.82-0.89) was greater than the amount of TV factor variance (0.11-0.19). Although TV factor stability was statistically significant for latent repetitive negative thinking, rumination, and worry, the magnitude of the coefficients was small. Furthermore, regression weights for the latent repetitive negative thinking, rumination, and worry TI factor were significant and larger than those for the TV factor in predicting insomnia symptoms at each of the six time points. These findings suggest that repetitive negative thinking is largely TI, and it is this TI component that contributes to insomnia symptoms. Implications for conceptualizations of repetitive negative thinking as a predisposing and perpetuating factor in insomnia for anxiety and related disorders are discussed.

Although attentional bias for threat has been implicated in anxiety disorders, traditional attentional bias measures have been criticized for lack of reliability and validity, and eye tracking technologies can be cost-prohibitive. MouseView.js was recently developed to mimic eye tracking online by using the computer cursor as a proxy for gaze, and although it is equally reliable, MouseView.js' utility for capturing attentional bias for threat in anxiety-related disorders remains unclear. To fill this knowledge gap, snake phobic and non-phobic participants (N = 62) completed a behavioral avoidance task (BAT) and the MouseView.js task which consisted of 10-second exposures to blurred, side-by-side images of either pleasant-neutral or threat-neutral pairings and were instructed to freely move the mouse to reveal the images. Results demonstrated that snake phobic participants had significantly shorter average mouse dwell time on threat images than non-phobic individuals and showed a significant reduction in average dwell time on threat images following the first presentation of the threat-neutral pairing. Additionally, dwell time on threat images significantly mediated the group differences in steps completed on the BAT. Results highlight the utility of MouseView.js in capturing avoidant patterns of attentional bias for threat that may also partially drive avoidance in snake phobia. Implications for capturing attentional bias for threat in anxiety disorders more broadly are discussed.

OBJECTIVE: Although self-disgust has been implicated in sexual assault-related posttraumatic stress disorder (PTSD), empirical evidence of this association is limited. METHOD: Participants with sexual assault-related PTSD (n = 19), sexual assault without PTSD (n = 20), and healthy controls (n = 21) completed "trait" measures of disgust proneness, self-disgust, and negative affect (NA; i.e., anxiety and depression). An ecological momentary assessment approach was also employed, where participants reported "state" levels of PTSD symptoms, self-disgust, and NA in the morning, afternoon, and evening for 1 week. RESULTS: Those with PTSD reported more trait disgust proneness, self-disgust, and NA than those who experienced sexual assault without PTSD and controls. However, those experiencing sexual assault without PTSD and controls did not differ from each other. Participants with a history of sexual assault also experienced higher self-disgust and NA during the week than controls. Those with higher PTSD symptoms during the week also experienced more self-disgust and NA. Similarly, changes in PTSD symptoms were associated with changes in self-disgust and NA during the week. Although a temporal association was found where NA predicted subsequent PTSD symptoms (and vice versa) during the week, a temporal link between self-disgust and PTSD symptoms (or vice versa) was not found. CONCLUSIONS: These findings suggest that the link between self-disgust and sexual assault-related PTSD is more correlational than causal. The implications of these findings for understanding how trait and state self-disgust fits within the broader emotional network of sexual assault-related PTSD are discussed.

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.

Consistent with the inhibitory retrieval approach, one proposed modification to improve the effectiveness of exposure-based interventions is to maximize variability by not proceeding linearly up an exposure hierarchy. Accordingly, the present study compares hierarchical and variable exposure interventions for contamination-fearful individuals and examines the role of uncertainty to predict intervention outcomes. Participants (N=73) were randomly assigned to complete a single-session exposure intervention using a standard hierarchy or a variable exposure intervention in which hierarchy items were randomly presented. Participants completed a behavioral approach task (BAT) at baseline and two follow-up visits over a two-week period. Both interventions resulted in a significant decrease in anxiety and disgust as well as more BAT steps completed but did not differ from one another. However, individuals in the variable exposure condition reported less variability in uncertainty during exposure compared to those in the standard condition, d=.78. Furthermore, lower levels of variability in uncertainty predicted greater reductions in anxiety and disgust post-intervention. Consistent with previous studies, variable exposure did not convey additional benefit over standard, hierarchical exposure. The experience of uncertainty during exposure is an important yet understudied process that warrants additional investigation.

Research has shown threat overestimation is significantly associated with intolerance of uncertainty (IU), and both processes predict higher anxiety and safety behavior usage. However, the extent to which threat overestimation predicts subsequent COVID-19-related distress may vary as a function of IU. The present study examined IU as a moderator of the relationship between COVID-19 threat estimation and subsequent COVID-19 fear and safety behavior use. Between February 27 and March 26, 2020, participants (N = 57) completed a self-report measure of IU and estimated the number of people they believed had died from COVID-19. Four weeks later, participants completed measures of COVID-19 fear and safety behavior use. Results revealed IU significantly predicted subsequent COVID-19 fear and safety behavior use. IU also moderated the effect of threat estimation on COVID-19 fear such that those who underestimated threat and experienced low to moderate levels of IU reported experiencing lower levels of COVID-19 fear 1 month later.

PURPOSE OF REVIEW: This review integrates recent systematic reviews and meta-analyses on the efficacy of cognitive behavioral therapy (CBT) for the treatment of anxiety disorders in children and adolescents. To inform personalized approaches to intervention, we also review recent research on moderators and predictors of outcomes. RECENT FINDINGS: Meta-analyses provide strong support for the efficacy of CBT for youth anxiety disorders, including with preschool-aged children using appropriate modifications. Furthermore, there is evidence that CBT is an effective adjunct treatment to psychopharmacological interventions, and the combination of treatments may be most effective for some youth. There is limited evidence of consistent demographic and clinical moderators of outcomes. Recent work in neuroscience has highlighted novel predictors of treatment outcomes that, with replication, may aid in more personalized approaches to youth anxiety treatment. CBT is efficacious for treating anxiety disorders in youth and lowering recurrence rates. CBT can also be an efficacious adjunct treatment for psychopharmacological interventions. Neuroimaging and psychophysiological measures of threat and motivational processing have shown initial promise in predicting symptom change with CBT, with potential implications for precision medicine.

Although heightened anxiety and health behavior use (i.e., masking, hand washing) may be viewed as an adaptive response to the coronavirus (COVID-19) pandemic, it is unclear how the politicization of the pandemic has influenced the trajectory of such responses. Accordingly, the present study examined differences between those that identify as more conservative or liberal in the trajectory of anxiety and health behaviors during the pandemic. This study also examines shifts in this trajectory before and after the presidential election. As part of a larger study, participants (N = 374) completed a symptom survey starting on May 27, 2020 every 2 weeks for a total of 15 timepoints over 30 weeks. The findings showed that more conservative participants reported lower levels of COVID-19 anxiety and less health behavior use compared to more liberal participants. In fact, anxiety levels increased slightly for more liberal participants and decreased slightly for more conservative participants during the pre-election time frame. Health behavior use also decreased more rapidly for conservative participants than for liberal participants during the pre-election time frame. However, COVID-19 anxiety and health behavior use rose sharply and similarly for both liberal and conservative individuals after the election. Importantly, these patterns were independent of state level variability in COVID-19 positivity and death rates. Subsequent analysis also revealed significant relations between COVID-19 anxiety and health behavior use that was slightly stronger among conservatives. Implications of these findings for navigating the influence of political ideology on anxiety-related responses during a public health emergency like the COVID-19 pandemic are discussed.

BACKGROUND: Accumulating evidence implicates sleep and circadian rhythm disturbance in obsessive-compulsive disorder (OCD). However, a multimethod characterization of sleep and circadian rhythms in OCD, their association with symptom severity, and the functional relationship between these variables is lacking. METHODS: The present study measured multiple indicators of sleep and circadian rhythms in a sample of adults with OCD, adults without OCD, and healthy controls (n = 74). Participants completed measures of morningness-eveningness, delayed sleep-wake phase disorder (DSWPD), insomnia symptoms, and OCD symptoms, as well as one week of sleep monitoring via a sleep diary and actigraphy. RESULTS: Delayed circadian rhythms (higher eveningness, later mid-sleep timing, and higher rates of DSWPD) and higher insomnia symptoms were observed in those with OCD compared to healthy controls, as well as associations between delayed circadian rhythms and insomnia symptoms and OCD symptom severity across the full sample. Further, insomnia symptoms mediated the relationship between delayed circadian rhythms and OCD symptoms. In contrast, there were no links between total sleep time or sleep quality and OCD. LIMITATIONS: Data collection during COVID-19 pandemic, correlational data, no physiological measure of circadian rhythms. CONCLUSIONS: These findings highlight a robust association between delayed circadian rhythms and OCD and suggest insomnia symptoms may be one mechanism in this relationship. Sleep and circadian rhythm disturbance may be novel targets for OCD treatment.

Obsessive-compulsive disorder (OCD) and illness anxiety disorder (IAD) often co-occur. Cognitive-behavioral models of both disorders overlap and include maladaptive attentional processes, misinterpretation of thoughts and physical sensations, and engagement in repetitive behaviors in an attempt to reduce associated distress. Given commonalities in their presentation and their common co-occurrence, it is important to understand how illness anxiety affects the presentation and treatment of OCD. In this article, theoretical conceptualizations of OCD and IAD and their comorbid presentation are outlined, and assessment and differential diagnosis of these conditions are discussed. Despite shared cognitive vulnerabilities and behavioral patterns, well-validated symptom measures, along with careful functional analysis, can be used to distinguish between OCD, IAD, and comorbid presentations. Best practices for the cognitive-behavioral treatment of these co-occurring conditions are also presented, with suggestions based on both the empirical literature and detailed case studies. Finally, recommendations for future research on co-occurring OCD and IAD and their treatment are explored.

Intolerance of uncertainty (IU) is the tendency to respond negatively toward uncertain situations. IU consists of a Prospective factor (desire for predictability) and an Inhibitory factor (uncertainty paralysis) and is central to theoretical approaches to obsessive-compulsive disorder (OCD). However, time-invariant (TI) and time-varying (TV) components of IU and their association with OCD symptoms are not yet understood. The present study examined the association between TI and TV components of IU and OCD symptoms in community adults (N = 1,280) over a 5-month period. Latent variable models were fit to the data to examine the relative impact of TI and TV components of IU on OCD symptoms. As a test of specificity, models examining the association between TI and TV components of IU and depressive symptoms were also examined. The results showed that IU consists of significant TI and TV components, although the TI component accounted for most of the variance (76-84%) and was more strongly associated with OCD and depressive symptoms than the TV component. Furthermore, the TI component of IU was strongly associated with OCD symptoms when controlling for depressive symptoms, and the TI component of IU was strongly associated with depressive symptoms when controlling for OCD symptoms. A consistent pattern was observed for both Prospective and Inhibitory IU factors, with stable TI components demonstrating stronger relations with OCD and depressive symptoms than TV components. These findings have implications for conceptualizing the TI component of IU as a risk for OCD and other emotional disorders.
