Article
For individuals with obsessive-compulsive disorder (OCD), family accommodation of symptoms, such as over-reassurance, participation in rituals, or facilitation of avoidance, is one of the key factors associated with symptom severity, maintenance, and related impairment. Most studies have assessed accommodation behaviors based on reports from family...
Article
Mental healthcare professionals often have limited awareness of different obsessive-compulsive disorder (OCD) symptom presentations, which may contribute to years between OCD symptom onset and treatment initiation. While research has identified high rates of OCD misdiagnosis among clinicians from the United States and Canada, research on OCD sympto...
Article
Childhood adversity and anxiety have been associated with increased risk for internalizing disorders later in life and with a range of brain structural abnormalities. However, few studies have examined the link between harsh parenting practices and brain anatomy, outside of severe maltreatment or psychopathology. Moreover, to our knowledge, there h...

This study examined (1) adolescent mental health literacy (MHL) and stigma for depression, anxiety and obsessive-compulsive and related disorders (OCRDs), and (2) demographic moderators. Participants were 383 high school students (50.9% boys) aged 11–18 years (M = 14.12, SD = 1.91) in El Salvador. Participants read vignettes of adolescents with men...
Article
Background : Cognitive-behavioral therapy (CBT) is the gold-standard psychotherapeutic treatment for pediatric negative valence disorders. However, some youths do not respond optimally to treatment, which may be due to variations in neural functioning. Methods : We systematically reviewed functional magnetic resonance imaging studies in youths wit...
Article
Deep transcranial magnetic stimulation (dTMS) has emerged as a treatment option for adults with obsessive-compulsive disorder (OCD) who continue to exhibit impairing symptoms following an adequate response to first line interventions. Currently, little is known about the predictors or moderators of dTMS outcome for OCD. This paper examined if sever...
Article
Body-focused repetitive behaviors (BFRBs) are recurrent behaviors targeting one or more body regions that may associate with negative outcomes. Little is known on their prevalence and correlates in psychiatric populations. This study examined the preliminary prevalence and correlates of BFRBs in 67 youth aged 9–17 years with primary anxiety-related...

The impact of externalizing comorbidity on treatment outcome was examined in 104 youth ages 7–16 (M = 11.09 years) with autism spectrum disorder and primary anxiety/obsessive compulsive disorder who completed modular cognitive behavioral therapy (CBT) for anxiety/OCD. Three comorbidity profiles were utilized for group comparisons: participants with...
Article
Chronic pain in adolescents can be highly impairing. Parental reactions to their child’s pain are important factors influencing pain perception and pain-related impairment in children and adolescents. The present study aimed to examine parental accommodation of pain symptoms using the Inventory of Parent Accommodations of Children’s Symptoms (IPACS...
Article

Previous studies have reported altered fear circuitry function during fear conditioning in highly anxious individuals and in adults with a history of severe childhood adversity; less is known regarding younger populations and more common forms of adversity. We investigated fear circuitry functioning in healthy youths with histories of high (HH) or...
Article
Little is known about the predictors of outcome from intensive residential treatment of OCD. This study aimed to examine age, gender, and baseline OCD severity, as well as measures of comorbid anxiety and depressive, internalizing/externalizing, and inattention symptoms, as predictors of treatment outcome in adolescents receiving intensive resident...
Article
Patient behaviors that may interfere with the process and outcome of therapy have been examined in the context of dialectical behavior therapy, but no measures exist to systematically characterize patient (or caregiver) treatment interfering behaviors (TIBs) in cognitive behavioral therapy (CBT) for anxiety disorders and obsessive-compulsive disord...

Public access full text: http://rdcu.be/wx2O. This study aimed to determine the effect of a multimodal residential treatment program for severe adolescent anxiety, and examine whether treatment outcome was associated with pre-treatment anxiety, comorbid disorders, or participant age or gender. Participants were 70 adolescents (61.4% female, mean ag...
Article
A significant proportion of the U.S. population report increased stress attributed to the political climate following the controversial 2016 United States (U.S.) Presidential election. The political stressors paired with the growth in news consumption and social media-use could be a potential trigger for obsessive-compulsive-like symptoms specific...
Article
Background: Body-Focused Repetitive Behaviors (BFRBs), including skin-picking, hair-pulling, and nail-biting, commonly occur in youth, even at elevated/problematic levels, and are associated with a number of other psychiatric symptoms. The present study examined the internal consistency of a brief screening tool for BFRBs as well as the prevalence...
Article
Background: Family accommodation is associated with a range of clinical features including symptom severity, functional impairment, and treatment response. However, most previous studies in children and adolescents investigated family accommodation in samples of youth with obsessive-compulsive disorder (OCD) or anxiety disorders receiving non-inte...

Article
Anxiety can either impair or enhance performance depending on the context. Increased sensitivity to threat seems to be an important feature of sensory processing in anxiety since anxious individuals tend to be more attentive to threatening visual stimuli. Evidence of anxiety effects in olfaction is rare; though alterations of olfactory performance...
Article
Although significant progress has been made over the last decades, the chemical senses remain less well explored than vision or audition. One method to assess participants' ability to identify or localize odors consists in the application of dichotomous stimuli (e.g. left and right sided stimulation). In this study we aimed to explore localization...
Article
Cross-modal interactions between vision, audition and touch have been extensively studied in the last decade. However, our understanding of how the chemical senses interact with other sensory modalities remains relatively scarce. We performed a cued auditory localization paradigm in healthy young adults by measuring reaction times to monaural audit...
Article
Odor stimuli presented to one nostril can only be localised if they additionally activate the trigeminal nerve's chemosensitive fibers. In this study we aimed to investigate characteristics in the localisation of unilateral trigeminal, olfactory and somatosensory nasal stimuli. We compared the ability of healthy young subjects to localise monorhina...
Article
Previous studies have shown that blind subjects may outperform the sighted on certain tactile discrimination tasks. We recently showed that blind subjects outperformed the sighted in a haptic 2D-angle discrimination task. The purpose of this study was to compare the performance of the same blind (n=16) and sighted (n=17, G1) subjects in three tacti...
