RESUMO
BACKGROUND: Anxiety disorders are the most common psychiatric problems among Canadian youth and typically have an onset in childhood or adolescence. They are characterized by high rates of relapse and chronicity, often resulting in substantial impairment across the lifespan. Genetic factors play an important role in the vulnerability toward anxiety disorders. However, genetic contribution to anxiety in youth is not well understood and can change across developmental stages. Large-scale genetic studies of youth are needed with detailed assessments of symptoms of anxiety disorders and their major comorbidities to inform early intervention or preventative strategies and suggest novel targets for therapeutics and personalization of care. METHODS: The Genetic Architecture of Youth Anxiety (GAYA) study is a Pan-Canadian effort of clinical and genetic experts with specific recruitment sites in Calgary, Halifax, Hamilton, Toronto, and Vancouver. Youth aged 10-19 (n = 13,000) will be recruited from both clinical and community settings and will provide saliva samples, complete online questionnaires on demographics, symptoms of mental health concerns, and behavioural inhibition, and complete neurocognitive tasks. A subset of youth will be offered access to a self-managed Internet-based cognitive behavioral therapy resource. Analyses will focus on the identification of novel genetic risk loci for anxiety disorders in youth and assess how much of the genetic risk for anxiety disorders is unique or shared across the life span. DISCUSSION: Results will substantially inform early intervention or preventative strategies and suggest novel targets for therapeutics and personalization of care. Given that the GAYA study will be the biggest genomic study of anxiety disorders in youth in Canada, this project will further foster collaborations nationally and across the world.

OBJECTIVE: Although the coronavirus disease 2019 (COVID-19) pandemic has had widespread negative impacts on the mental health of healthcare workers (HCWs), there has been little research on psychological interventions during the pandemic for this population. The current study examines whether a brief coping-focused treatment intervention delivered in a virtual individual format would be associated with positive changes in Canadian HCWs' mental health during the pandemic. METHOD: Three hundred and thirty-three HCWs receiving the intervention at 3 large specialty tertiary care hospitals in Ontario, Canada, completed measures of anxiety, depression, perceived stress, work/social impairment, insomnia and fear of COVID-19. After completing treatment, HCWs rated their satisfaction with the treatment. RESULTS: The intervention was associated with large effect size improvements in anxiety, depression, perceived stress, insomnia and fear of COVID-19, and moderate effect size improvements in work/social impairment. At treatment session 1, prior mental health diagnosis and treatment were both significantly correlated with depression, anxiety, and work/social impairment scores. Secondary analyses of data from one of the sites revealed that treatment-related changes in anxiety, depression, perceived stress and work/social impairment were independent of age, gender, occupational setting, profession and the presence of a previous mental health diagnosis or treatment, with the exception that nurses improved at a slightly greater rate than other professions in terms of work/social impairment. HCWs were highly satisfied with the treatment. CONCLUSIONS: A large number of HCWs experiencing significant distress at baseline self-referred for assistance. Timely and flexible access to a brief virtual coping-focused intervention was associated with improvements in symptoms and impairment, and treatment response was largely unrelated to demographic or professional characteristics. Short-term psychological interventions for HCWs during a pandemic may have a highly positive impact given their association with improvement in various aspects of HCWs' mental health improvement.

OBJECTIVES: Those close to people with mental health difficulties (e.g., family members, romantic partners and close friends) are often involved in their care decisions. Research shows that criticism by close others and accommodation of symptoms are associated with symptom severity and treatment response. Recent research has found that those close to someone with an anxiety disorder report a range of concerns about their loved one starting cognitive-behaviour therapy (e.g., that treatment will cause the person to change in undesirable ways). The purpose of this study was to examine the relationship between close others' criticism and symptom accommodation and their treatment concerns, hypothesizing that these relationships would be significant. DESIGN: Close others to those with notable anxiety (N = 287) completed self-report measures online. Multiple regression was used to test our hypothesis. METHODS: Respondents who identified as being close to someone with notable anxiety completed measures of their accommodation of anxiety symptoms, feelings of criticism/hostility towards them, concerns about them starting treatment, perceived impairment due to anxiety, and their own and their loved ones' treatment history. RESULTS: Greater criticism and accommodation significantly predicted greater treatment concerns, with a medium effect size, controlling for degree of impairment due to anxiety and treatment history. CONCLUSIONS: Criticism and accommodation may reflect appraisal of the person with anxiety as weak or fragile, which may evoke concerns about treatment success. Implications for clinicians and anxiety treatment are discussed.

BACKGROUND: Many people with anxiety do not seek therapy due to negative views of treatment. Although close others (e.g. romantic partners, family members, close friends) are highly involved in treatment decisions, the role of specific relational behaviours in treatment ambivalence has yet to be studied. AIMS: This study examines the relationship between social predictors (perceived criticism and accommodation of anxiety symptoms by close others) and treatment ambivalence. METHOD: Community members who met diagnostic criteria for an anxiety-related disorder (N = 65) and students who showed high levels of anxiety (N = 307) completed an online study. They were asked to imagine they were considering starting cognitive behavioural therapy (CBT) for their anxiety and complete a measure of treatment ambivalence accordingly. They then completed measures of perceived criticism and accommodation by close others. Linear regression was used to examine the predictive value of these variables while controlling for sample type (clinical/analogue) and therapy experience. RESULTS: Greater reactivity to criticism from close others and greater accommodation of anxiety symptoms by close others were associated with greater treatment ambivalence in those with anxiety. These predictors remained significant even when controlling for therapy history and sample type. CONCLUSIONS: When it comes to treatment attitudes, relational context matters. Clients demonstrating ambivalence about starting therapy may benefit from discussion about the impact of their social environment on ambivalence.

BACKGROUND: Safety behaviours are hypothesized to play a vital role in maintaining social anxiety disorder (SAD), in part by orienting socially anxious individuals to adopt an avoidance-based mindset focused on self-protection and self-concealment. Evidence suggests an association between safety behaviour use and negative social outcomes for individuals with SAD. However, research has largely focused on the broad group of safety behaviours, whereas specific subtypes have received less attention. AIM: The present study aimed to further our understanding of the negative interpersonal consequences of specific types of safety behaviours for individuals with SAD by examining whether active, inhibiting/restricting, or physical symptom management safety behaviour use affects perceived likeability and authenticity during a conversation with a stranger. METHOD: Individuals with SAD (n = 29; mean age 35.5 years) and healthy control (non-SAD) participants (n = 40; mean age 18.6 years) engaged in a semi-structured social interaction with trained confederates. RESULTS: Participants with SAD were perceived as significantly less likeable and authentic by the confederates, and rated themselves as significantly less authentic compared with those without SAD. The association between group status and likeability was mediated by the use of inhibiting/restricting safety behaviours and the association between group status and participant-rated authenticity was mediated by the use of both inhibiting/restricting and active safety behaviours, but not physical symptom management strategies. CONCLUSIONS: These results contribute to a growing literature suggesting that some, but not all, safety behaviours may play an important role in creating the negative social outcomes that individuals with SAD experience.

Cognitive behavioural therapy (CBT) including exposure and response prevention is the first-line psychological treatment for obsessive compulsive disorder (OCD). Given changes in the clinical landscape, there are increasing efforts to evaluate its effectiveness in online contexts. Mirroring the traditional in-person delivery, few studies have assessed the role of therapist-guided, manual-based CBT for OCD delivered in real-time via videoconferencing methods. The present study sought to fill this gap by comparing in-person and online delivery of group-based CBT for the treatment of OCD. A convenience sample of participants with moderate to severe OCD (n = 144) were recruited from a naturalistic database from two large OCD specialty assessment and treatment centres. Patients received group-based CBT that was provided in-person (pre-COVID-19 pandemic; March 2018 to March 2020) or online via videoconferencing (during the COVID-19 pandemic; March 2020 to April 2021). In both delivery methods, treatment consisted of 2-h weekly sessions led by trained clinicians. Analyses revealed that, regardless of treatment modality, both in-person and online groups demonstrated significant, reliable, and statistically equivalent improvements in OCD symptoms post-treatment. Videoconferenced, clinician-led CBT may be a promising alternative to in-person delivery for those with moderate to severe OCD symptoms.
RESUMO
OBJECTIVE: Telehealth is being increasingly incorporated into the delivery of mental health care and has received widespread attention during the COVID-19 pandemic for its ability to facilitate care during physical distancing restrictions. Videoconferencing is a common telehealth modality for delivering psychotherapy and has demonstrated similar outcomes to those of face-to-face therapy. Cognitive behavioural therapy (CBT) is the most common psychotherapy evaluated across various telehealth modalities; however, studies on CBT delivered via videoconference, particularly in a group therapy format, are lacking. Further, little research exists on videoconference group CBT for anxiety disorders. Accordingly, the present study compared the outcomes of group CBT for anxiety and related disorders delivered via videoconference versus face-to-face. METHOD: Using a non-randomized design, data on attendance, dropout, clinical outcomes, and functional impairment were collected from 413 adult outpatients of a tertiary care anxiety disorders clinic who attended a CBT group for panic disorder/agoraphobia, social anxiety disorder, generalized anxiety disorder (GAD), or obsessive-compulsive disorder delivered either face-to-face (pre-COVID-19 pandemic) or via videoconference (since the onset of COVID-19 pandemic). Outcomes were assessed using well-validated self-report measures. Data were collected pre-treatment, across 12 weekly sessions, and post-treatment. Intent-to-treat analyses were applied to symptom outcome measures. RESULTS: Face-to-face CBT conferred only a slight benefit over videoconference CBT for symptom outcomes across all groups, but when assessed individually, only the GAD group showed greater symptom improvement in the face-to-face format. Effect sizes for significant differences between the delivery formats were small. Participants in videoconference groups tended to have slightly higher attendance rates in some instances, whereas functional improvement and treatment dropout were comparable across the delivery formats. CONCLUSIONS: Results provide preliminary evidence that videoconference group CBT for anxiety and related disorders may be a promising and effective alternative to face-to-face CBT. Additional research is needed to establish equivalence between these delivery formats.

The Posttraumatic Stress Disorder (PTSD) Checklist for DSM-5 (PCL-5) is a widely used, self-report measure that is employed to assess PTSD symptom severity and determine the presence of probable PTSD in various trauma-exposed populations. The PCL-5 is often administered in clinical settings as a screening tool for PTSD, with a suggested cutoff score of 33 indicating a probable PTSD diagnosis. Recent research indicates that a higher cutoff may be required in psychiatric samples. In the present study, we aimed to determine the sensitivity and specificity of the PCL-5 in a Canadian outpatient psychiatric sample and establish an optimal cutoff score for detecting probable PTSD in this sample. Participants were 673 individuals who reported a history of trauma exposure and were assessed using a semistructured interview and self-report measures. Individuals diagnosed with PTSD (N = 193) reported a mean PCL-5 score of 56.57, whereas individuals without PTSD (N = 480) reported a mean score of 33.56. A score of 45 was determined to be the optimal cutoff score in this sample, balancing sensitivity and specificity while detecting a probable diagnosis of PTSD. Consistent with findings in other psychiatric samples, these findings indicate that in an outpatient psychiatric sample with a history of exposure to a variety of trauma types, a higher cutoff score is required to determine probable PTSD. In addition, given the estimated rate of false positives even with a higher cutoff, follow-up diagnostic assessments are recommended.

BACKGROUND: Individuals with hoarding report stressful and traumatic life events at an elevated rate compared with those with obsessive-compulsive disorder and healthy controls, but have not been compared with other clinical groups. This study compared rates of traumatic life events between those with clinically significant hoarding, anxiety disorders, or posttraumatic stress disorder (PTSD), hypothesizing that rates would be higher in the hoarding and PTSD groups than the anxiety group. METHODS: Rates of traumatic and stressful events were compared across groups. RESULTS: All comparisons across groups on types of events were significant (partial-eta squared 0.051-0.162). The hoarding group endorsed significantly more crime-related events but similar rates of other events as compared to the PTSD and anxiety disorder groups. CONCLUSION: These findings suggest that many stressful and traumatic life events are not uniquely elevated in hoarding when compared with other clinical populations.

OBJECTIVE: The literature on transdiagnostic psychotherapy among youths is limited. Group transdiagnostic behavior therapy (TBT) has been shown to be effective for adults with affective disorders and may contain beneficial features for youths (e.g., behavioral focus, group format, ease of dissemination, and diversity of targeted diagnoses). This study aimed to investigate group TBT among youths in Canada to determine its feasibility and efficacy. METHODS: Twenty participants (ages 16-19) diagnosed as having a principal anxiety disorder completed 12 sessions of group TBT. Symptoms of anxiety, depression, and transdiagnostic impairment were assessed pre- and posttreatment. RESULTS: Participants demonstrated significant improvements on measures of anxiety (general, cognitive, and somatic) and stress, with moderate effect sizes. Findings for symptoms of depression and transdiagnostic impairment were unreliable, with small effect sizes. CONCLUSIONS: These findings provide preliminary support for the use of group TBT among youths with anxiety disorders. Future research should incorporate comparison groups and larger samples.

BACKGROUND: Transdiagnostic psychotherapies are designed to apply the same underlying treatment principles across a set of psychiatric disorders, without significant tailoring to specific diagnoses. Several transdiagnostic psychotherapy protocols have been developed recently, each of which has its own strengths and weaknesses. One promising treatment is Transdiagnostic Behaviour Therapy (TBT), in that it is one of the few transdiagnostic treatments to date shown to be effective in patients with depressive and anxiety disorders. However, TBT has only been investigated via individual psychotherapy. AIMS: The present study investigated the effectiveness of a group protocol for TBT, compared with disorder-specific group psychotherapies, in a naturalistic setting. METHOD: 109 participants with various diagnoses of affective disorders completed either group TBT (n = 37) or a disorder-specific group psychotherapy (n = 72). Measures included assessments of psychiatric symptomatology and transdiagnostic impairment at baseline and post-treatment. RESULTS: Overall, participants in the TBT group demonstrated significant improvements across all measures. When compared with disorder-specific groups, no statistical differences were observed between groups across symptoms; however, participants in the TBT group demonstrated roughly twice the treatment effect sizes in transdiagnostic impairment compared with participants in the disorder-specific groups. In addition, when participants from the most well-represented diagnosis and disorder-specific treatment (social anxiety disorder) were investigated separately, participants in the TBT group demonstrated significantly larger improvements in comorbid depressive symptoms than participants in the disorder-specific treatment. CONCLUSIONS: Pending replication and additional comparison studies, group TBT may provide an effective group treatment option for patients with affective disorders.

The Children's Saving Inventory (CSI) was introduced in 2011 and is the first parent-rated questionnaire specifically designed to measure the severity of hoarding symptoms in youth. To date, however, no replication studies of the CSI have been published. Additionally, the total CSI score includes several items measuring acquisition, a behavioural dimension that has since been excluded from DSM-5's hoarding disorder criteria. Given these limitations, the primary goal of the present study was to test a modified, DSM-5-consistent, total score of the CSI. Because a confirmatory factor analysis did not support the 2011 four-factor model of the CSI, we reviewed the original CSI and excluded all acquisition items. An exploratory factor analysis yielded a strong three-factor solution (difficulty discarding, Clutter, and distress/impairment) with good reliability and validity for a 15-item version of the CSI. Overall, our results support the use of the 15-item CSI in youth with OCD.

A significant number of obsessive-compulsive disorder (OCD) patients continue to experience symptoms that interfere with their functioning following cognitive behavioural therapy (CBT). Providing an additional augmentation treatment following CBT could help reduce these residual symptoms. Mindfulness interventions that facilitate less reactivity to thoughts and feelings may be helpful for patients suffering from residual OCD symptoms. The purpose of the current randomized waitlist control trial was to evaluate the feasibility and impact of providing an 8-week mindfulness-based cognitive therapy (MBCT) intervention following completion of a CBT intervention to OCD patients who continued to suffer from significant symptoms. Results indicated that compared to the waitlist control group, MBCT participants reported decreases in OCD symptoms (d = 1.38), depression symptoms (d = 1.25), anxiety symptoms (d = 1.02), and obsessive beliefs (d = 1.20) along with increases in self-compassion (d = 0.77) and mindfulness skills (d = 0.77). Additionally, participants reported high levels of satisfaction with the MBCT intervention. The results suggest that the use of MBCT for OCD as an augmentation therapy is acceptable to patients who continue to suffer from OCD symptoms after completing CBT and provides some additional relief from residual symptoms. KEY PRACTITIONER MESSAGE: Mindfulness interventions teach skills that facilitate disengaging from cognitive routines and accepting internal experience, and these skills may be valuable in treating obsessive-compulsive disorder (OCD), as individuals describe getting "stuck" in repetitive thoughts and consequent rituals. The results of this study suggest that teaching mindfulness skills using an 8-week mindfulness-based cognitive therapy (MBCT) intervention provides an added benefit (decreases in OCD, depression, and anxiety symptoms) for patients with OCD who have completed a cognitive behavioural therapy intervention and continued to suffer from significant symptoms. Participation in MBCT was also associated with increases in mindfulness skills including increased ability to be nonjudgmental and nonreactive. By fostering a nonjudgmental stance towards intrusive thoughts, mindfulness may discourage suppression and avoidance of thoughts and this could lead to increased habituation and a decreased reliance on compulsions. The use of MBCT as an augmentation treatment should be further explored to elucidate whether this treatment is beneficial for preventing relapse of OCD and could be compared against further cognitive behavioural therapy to see if offering participants a different and theoretically compelling intervention, such as MBCT, would outperform "more of the same" for individuals with OCD.

BACKGROUND: Post-event processing (PEP) occurs when individuals engage in cognitive rumination following an event or interaction. Although the relation between PEP and social anxiety has been clearly demonstrated, it remains unclear whether PEP is limited to individuals with elevated social anxiety, or if it is also problematic among people with other anxiety presentations. AIMS: The present study assessed PEP after the first session of group cognitive behavioural therapy (CBT) in individuals with a variety of anxiety presentations. METHOD: Participants with a principal diagnosis of SAD (N = 25), those diagnosed with a principal other anxiety disorder with comorbid SAD (N = 18), and those with principal other anxiety diagnoses with no SAD (N = 43) completed baseline measures of social anxiety severity and state anxiety at their first session of CBT and measures of PEP one week later. RESULTS: Participants with a principal diagnosis of SAD experienced the most PEP in the week following the first CBT session, while those with no comorbid SAD experienced the least. Those with comorbid SAD experienced intermediate levels of PEP. The strongest predictor of PEP was state anxiety during the first session. CONCLUSIONS: Results suggest that PEP is more problematic for clients with SAD as part of their clinical presentation. Clinical and theoretical implications are discussed.

OBJECTIVES: There are a number of effective psychological interventions for anxiety disorders. Anecdotal and empirical evidence indicates that clients are often highly apprehensive about commencing therapy. However, to date, there have been no empirical studies of the content of individuals' fears about beginning a psychological treatment for anxiety problems. Here we describe the development and initial validation of the Treatment Ambivalence Questionnaire (TAQ), a 30-item self-report measure of concerns about commencing psychological treatment for anxiety. METHODS: Participants were a large group of individuals with a principal diagnosis of an anxiety disorder who were referred to a specialty anxiety disorders clinic. Participants completed the TAQ as well as several general self-report instruments before commencing treatment. RESULTS: The TAQ exhibited good internal consistency and, based on exploratory factor analyses, the items yielded three subscales: (a) fears of the personal consequences of engaging in treatment (e.g., personality change), (b) fears of negative or adverse reactions to treatment (e.g., not getting better), and (c) concerns about the inconvenience of engaging in treatment (e.g., treatment will be time-consuming). Confirmatory factor analysis supported this factor structure. Scores on the TAQ did not simply represent general symptom severity or distress. Preliminary data on the relation of TAQ scores to treatment outcome suggested either no relationship or a small relationship. CONCLUSION: The TAQ may be a useful means of normalizing treatment fears, identifying and addressing specific fears, and identifying people who may benefit from treatment readiness interventions.

BACKGROUND: Post event processing (PEP) in social anxiety disorder involves rumination about social events after the fact, and is thought to be a crucial feature of the maintenance of the disorder. AIMS: The current experiment aimed to manipulate the use of PEP in individuals with social anxiety disorder. METHOD: Forty-one individuals with social anxiety disorder completed a videotaped speech. Anxiety ratings and degree of PEP were measured after the task as well as the day following the experiment. RESULTS: Individuals in the distract group reported a greater decrease in anxiety from baseline to post-experimental task than those asked to focus. Individuals in the distract group also reported higher PEP about the task than those instructed to complete a focus task, which appeared to be partially accounted for by baseline differences in symptom severity and state anxiety. Degree of PEP was positively correlated with anxiety ratings, both after the experimental task as well as 24 hours later. CONCLUSIONS: These findings suggest that naturalistic PEP is problematic for individuals with social anxiety disorder, especially for those with more severe symptoms. A distraction task, even with breakthrough PEP, appears to have useful short-term effects on anxiety reduction as compared to focus instructions.

Adults with clinical anxiety have significant symptom overlap and above average rates of attention-deficit/hyperactivity disorder (ADHD). Despite this, ADHD remains a vastly under-detected disorder among this population, indicating the need for a screener with well-understood symptom dimensions and good discriminant validity. The current study compared competing models of ADHD as well as discriminant properties of self-reported ADHD symptoms as measured by the Adult ADHD Self-Report Scale (ASRS-v1.1) in 618 adults with clinical anxiety. A three-factor correlated model of Inattention, Impulsivity, and Hyperactivity, with the movement of one item, talks excessively, to a factor of Impulsivity from Hyperactivity fit better than the one-factor, two-factor, and traditional three-factor models of ADHD. Discriminant properties of the screener were fair to good against measures of clinical anxiety and distress; however, some items within the Hyperactivity factor (e.g., difficulty relaxing; feeling driven by a motor) loaded more strongly onto factors of clinical anxiety than ADHD when measures were pooled together. These results suggest that clinicians making differential diagnoses between adult ADHD and anxiety or related disorders should look for evidence of ADHD beyond the overlapping symptoms, particularly for those within the Hyperactivity factor.
RESUMO
BACKGROUND: Obsessive-compulsive disorder (OCD) has been associated with neurocognitive impairments. The present study examined the effect of treatment on neurocognitive performance in OCD and the relationship between neurocognitive change and symptom change. The present study also examined polymorphisms influencing brain derived neurotrophic factor (BDNF) as predictors of neurocognitive change. METHOD: Treatment-seeking participants with OCD (N = 125) were assigned to cognitive behavioural therapy (CBT) alone, CBT combined with regular physical exercise, exercise alone, or a waitlist control group. Measures of OCD symptom severity and a neuropsychological battery were completed pre- and post-treatment. Blood or saliva samples were used to genotype the BDNF Val66Met polymorphism. RESULTS: OCD symptom severity was not cross-sectionally associated with neurocognitive performance. Several neurocognitive measures improved over treatment. The BDNF Val66Met polymorphism was significantly associated with worse performance on the Stroop test but did not significantly predict change in neurocognitive performance over time. LIMITATIONS: Limitations include lack of a healthy control group. CONCLUSION: Improvement in neurocognitive performance corresponded to symptomatic improvement and was independent of the BDNF Val66Met genotype.

Although much is known about how intrusive thoughts become obsessions, the factors that determine which particular thoughts do so is not. The degree to which intrusions are personally significant may be such a determinant. Obsessive-compulsive disorder (OCD) is heterogeneous; thus, it is possible that contradictions of personal values may play a varying role in the development of obsessions depending on which OCD symptoms manifest and may change differentially following treatment. Archival data were examined. Patients with a diagnosis of OCD (N = 62) reported their most upsetting obsession and the degree to which it violated values both pre- and postparticipation in group cognitive-behavioral therapy for OCD. At pretreatment, contradiction ratings differed across symptom domains, such that participants with primary symptoms of obsessions/checking exhibited contradiction ratings that were significantly greater than did participants with other primary symptoms. Contradiction ratings did not change posttreatment. Implications for the conceptualization of OCD are discussed.

Post-Event Processing (PEP) is prevalent and problematic in Social Anxiety Disorder (SAD) but is typically not a direct target in evidence-based treatments such as cognitive behavioural therapy (CBT) for SAD. The primary aim of the current study was to examine the impact of several theoretically and empirically derived interventions for PEP in SAD, including concrete thinking, abstract thinking, and distraction in comparison to a control (i.e., do nothing) condition. Based on prior research, we hypothesized that the concrete and distract conditions would be associated with positive benefits, including reductions in PEP and improvements in self-perception, whereas the abstract and control conditions would not. The second aim of the study was to identify baseline variables that predict the trajectory of change in PEP over time. Participants (N=92) with a principal diagnosis of SAD completed a social stress task and were randomly assigned to one of four conditions. Participants completed measures at baseline, post-intervention/control, and at 1-week, and 1-month follow-up. Contrary to hypotheses, all three active conditions were similarly effective at reducing PEP and improving self-perceptions relative to the control condition. In the absence of an intervention, engagement in PEP remained high up to a month following the social stress task. Higher levels of baseline state anxiety, intolerance of uncertainty, and use of safety behaviours predicted greater PEP, even in the presence of an intervention. These results highlight the benefits of relatively brief interventions that disrupt the course of PEP for people with SAD. Such interventions can be easily incorporated into CBT protocols for SAD to enhance their effects.
