RESUMEN
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.

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.

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.
RESUMEN
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.

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.
RESUMEN
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.

PURPOSE: Cognitive behavioural therapy (CBT) has been found to be an effective treatment for OCD, but there remains a significant proportion of individuals who fail to show a treatment response. Aerobic exercise has previously been associated with decreases in anxiety and depression, as well as improvements in OCD symptoms in small-scale studies. The purpose of the present research was to use a randomized control trial design to examine the effects of exercise alone and in combination with CBT, on OCD symptoms and secondary symptoms. METHOD: 125 participants were randomly assigned to one of four treatment groups: waitlist control, exercise, CBT, and CBT with exercise. OCD symptom severity was measured at four points over the course of treatment, secondary outcome measures were gathered at three points over treatment. RESULTS: CBT alone and combined with exercise was associated with significantly greater OCD symptom reduction than exercise alone or the control groups. Total exercise frequency predicted OCD symptom reduction in the groups in which exercise was measured. Group membership did not significantly predict reductions in secondary outcome measures. CONCLUSION: Exercise frequency, rather than the presence or absence of exercise, appears to predict OCD symptom reduction, as did participation in CBT.

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.

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.

OBJECTIVES: The current study examined whether cannabis use frequency and cannabis-related problem severity (as per the Cannabis Use Disorder Identification Test-Revised) predicted outcomes of cognitive behavioural therapy (CBT) for anxiety and related disorders. It was predicted that greater frequency of cannabis use and greater cannabis-related problem severity would be associated with dampened treatment outcomes compared to less severe cannabis use presentations. METHODS: Participants were 253 adults seeking treatment for anxiety and related disorders. Cannabis use was categorized as non-use (n = 135), infrequent use (using monthly to 4 times per month; n = 45), and frequent use (using 2 or more times per week; n = 73). Individuals who reported using cannabis completed cannabis use and cannabis-related problem measures before starting a CBT group. Participants also completed a weekly symptom-specific measure of anxiety symptoms throughout CBT. RESULTS: As hypothesized, frequent cannabis use was associated with poorer outcomes in CBT for anxiety and related disorders compared to non-use. Despite this, individuals who used cannabis frequently still experienced a statistically significant decrease in their anxiety symptoms from pre-to post-CBT, with a large effect size (d = -0.87). Cannabis-related problems was not a significant predictor of CBT outcomes. CONCLUSIONS: Cannabis use frequency was associated with poorer CBT outcomes for anxiety and related disorders, however these individuals still made notable treatment gains. The mechanism driving this relationship remains unclear. Future studies should attempt to replicate the current findings and examine possible mechanisms.

OBJECTIVE: Few studies have examined cannabis motives in adults and, although associations between cannabis use and psychiatric conditions are well documented, there has been limited investigation of the intersection of cannabis use, cannabis motives, and psychopathology. In a sample of community adults, the present study examined cannabis motives in relation to cannabis misuse, and investigated whether motives linked cannabis misuse with concurrent psychiatric symptoms. METHOD: Participants (N = 395; M age = 34.8; %F = 47.6; % White = 81.3%) completed assessments related to cannabis misuse, cannabis use motives, and symptoms of depression, anxiety, PTSD, and somatic experiences. Bivariate correlations, hierarchical regressions, and indirect effect analyses were performed to examine associations between motives and cannabis misuse and to investigate mechanistic relationships between psychiatric symptoms and cannabis misuse. RESULTS: Regressions revealed significant associations between cannabis misuse and social (ß = .13, P < .02), enhancement (ß = .12, P < .02), and coping motives (ß = .48, P < .001). Indirect effects were present such that coping motives consistently linked psychiatric and somatic symptoms with cannabis misuse (anxiety: unstandardized effect = 0.26,and 95% CI = 0.17-0.37; depression: unstandardized effect = 0.12, CI = 0.11-0.25; PTSD: unstandardized effect = 0.07, CI = 0.04-0.10; somatic symptoms: unstandardized effect = 0.20, CI = 0.11-0.30). In addition, enhancement motives exhibited an indirect effect (unstandardized effect = 0.02, CI = 0.002-0.04) between depressive symptoms and cannabis misuse. CONCLUSION: These results support a negative reinforcement motivational profile as the predominant pattern in adult cannabis users, albeit with links to enhancement and social motives. This motivational profile is especially pronounced with regard to comorbid psychopathology and cannabis misuse. These results support the importance of treatment strategies targeting maladaptive coping to address cannabis misuse and co-occurring psychopathology.
RESUMEN
Background: The close others (e.g., family members, romantic partners) of people with anxiety and related disorders are typically involved in their treatment decisions. However, we know little about close others' attitudes towards and concerns about their loved one starting cognitive-behavioural therapy (CBT). Methods: Study one surveyed close others of those with anxiety and related disorders (n = 33) about their concerns about their loved one starting CBT. Thematic coding was completed, and items were developed to reflect these themes, comprising a measure of treatment concerns in close others. Study two involved the administration of the novel measure to a larger sample (n = 287) to evaluate its structure, reliability, and validity. Results: Close others endorsed having treatment concerns of moderate intensity. The final 17-item measure, the Treatment Concerns Questionnaire-Close Others (TCQ-C), has a robust four-factor structure, with internally consistent subscales including "Adverse Reactions", "Personal/Family Consequences", "Lack of Commitment", and "Ineffectiveness". The measure shows moderate correlations with treatment expectations (convergent validity) and small correlations with respondent distress (discriminant validity). Conclusions: The value of this measure for clinicians and future directions for research are discussed.

RESUMEN
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.

This article describes the initial validation of the Diagnostic Assessment Research Tool (DART), a modular semistructured interview to facilitate diagnosis of various disorders among adults corresponding with the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5). In this study, the construct, convergent, and discriminant validity of DART modules for anxiety disorders, depressive disorders, obsessive-compulsive disorder, posttraumatic stress disorder, and substance-related and addictive disorders was assessed among a sample of 610 participants in a clinical outpatient setting. The data indicated excellent construct validity among DART modules assessed. Individuals with and without DSM-5 diagnoses identified via the DART had significant between-group differences on self-report measures corresponding to these diagnoses. Follow-up logistic regressions supported convergent validity for all diagnostic categories assessed. Discriminant validity was established for the majority of diagnostic categories assessed. High rates of interrater agreement in a small subsample (n = 15) were observed for the various diagnostic categories of the DART (88% average agreement). The results of the present study provide initial support for the DART as a useful tool to aid in the assessment of several major diagnostic categories corresponding with DSM-5 disorders.

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.

Executive functions (EF) deficits are hypothesized to be a core contributor to hoarding symptoms. EF have been studied in adult hoarding populations, but studies in youth are lacking. The current study compared multiple EF subdomains between youth with obsessive-compulsive disorder (OCD) and youth with OCD and hoarding symptoms. Forty youth (8-18 years old) with a primary diagnosis of OCD were recruited. Participants were divided by hoarding severity on the Child Saving Inventory (CSI) into either the "hoarding group" (upper 33.3%) or the "low-hoarding group" (lower 66.7%). Groups were compared on EF tasks of cognitive flexibility, decision-making, and inhibitory control. Youth in the hoarding group exhibited significantly higher cognitive flexibility and lowered perseveration than the low-hoarding group. Hoarding and low-hoarding groups did not differ in any other EF subdomain. Hoarding symptoms in youth with OCD were not associated with deficits in EF subdomains; instead, youth who hoard exhibited higher cognitive flexibility compared to youth with low hoarding symptoms.

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.
