Purpose: Anxiety sensitivity (AS) and experiential avoidance (EA) are associated with anxiety in both adults and youths. This study examined the separate contributions of AS and EA in predicting (a) anxiety (symptom severity) and (b) differential treatment outcomes in anxious youth receiving cognitive behavioral therapy (CBT).

Methods: Participants ( = 89; age 10-17 years; 37% male; 78% white) met diagnostic criteria for an anxiety disorder and received CBT ().

Background: Efforts to identify risk and resilience factors for anxiety severity and course during the COVID-19 pandemic have focused primarily on demographic rather than psychological variables. Intolerance of uncertainty (IU), a transdiagnostic risk factor for anxiety, may be a particularly relevant vulnerability factor.

Method: N = 641 adults with pre-pandemic anxiety data reported their anxiety, IU, and other pandemic and mental health-related variables at least once and up to four times during the COVID-19 pandemic, with assessments beginning in May 2020 through March 2021.

Objective: At the onset of the COVID-19 pandemic, telehealth service use increased. However, little research has compared the efficacy of individual cognitive behavioral therapy (CBT) for youth with anxiety administered via (a) telehealth and (b) in-person. The present study used non-inferiority analyses to examine outcomes for youth with anxiety disorders (diagnosed by an Independent Evaluator; IE) treated via telehealth during the COVID-19 pandemic and youth treated via in-person therapy prior to the COVID-19 pandemic.

Objective: This study (a) examined anxious youth with and without asthma on measures of negative self-talk, parental psychopathology, worry content, physical symptoms, panic symptoms, generalized symptoms, and separation anxiety symptoms, and (b) tested if outpatient CBT or medication were differentially effective in reducing anxiety for youth with asthma and anxiety.

Methods: This secondary analysis separated youth with an anxiety disorder into asthma and non-asthma groups. Youth were also compared on response to treatments (i.

Considerable work has advanced understanding of the nature, causes, management, and prevention of anxiety disorders in children and adolescents over the past 30 years. Prior to this time the primary focus was on school refusal and specific phobias. It is now recognised that children and adolescents experience the full gamut of anxiety disorders in very similar ways to adults and that anxiety disorders in the paediatric years can predict a lifelong mental-health struggle.

Background: Anxiety disorders are highly prevalent and debilitating conditions that show high comorbidity rates in adolescence. The present article illustrates how Unified Protocol for Transdiagnostic Treatment of Emotional Disorders in Adolescents (UP-A) was adapted for Iranian adolescents with anxiety disorders.

Methods: A total of 54 adolescents with comorbid anxiety disorders participated in a randomized, waitlist-controlled trial of group weekly sessions of either UP-A or waitlist control (WLC).

Background: To bring evidence-based interventions (EBIs) to individuals with behavioral health needs, psychosocial interventions must be delivered at scale. Despite an increasing effort to implement effective treatments in communities, most individuals with mental health and behavioral problems do not receive EBIs. We posit that organizations that commercialize EBIs play an important role in disseminating EBIs, particularly in the USA.

Cognitive behavioral therapy (CBT) is an efficacious therapy for youth anxiety disorders. Caregivers are key stakeholders in youth therapy, and their feedback on treatment can help to inform intervention personalization. This mixed-methods study applied a systematic inductive thematic analysis to identify themes among most- and least-liked CBT features reported by caregivers using open-ended responses on the Client Satisfaction Questionnaire (CSQ-8).

Objective: The current study examined trajectories of anxiety during (a) acute treatment and (b) extended follow-up to better characterize the long-term symptom trajectories of youth who received evidence-based intervention for anxiety disorders using a person-centered approach.

Method: Participants were 319 youth (age 7-17 years at enrollment), who participated in a multicenter randomized controlled trial for the treatment of pediatric anxiety disorders, Child/Adolescent Anxiety Multimodal Study, and a 4-year naturalistic follow-up, Child/Adolescent Anxiety Multimodal Extended Long-term Study, an average of 6.5 years later.

Anxiety disorders are common in youth, associated with impairments in daily functioning, and often persist into adulthood when untreated. Cognitive behavioral therapy (CBT) for youth anxiety is a well-established intervention and has been modified to fit several treatment settings. Despite decades of results supporting the efficacy of CBT, there is a large gap in access to this treatment and a need to consider how it can best be administered flexibly to increase uptake and personalization.

Interventionists interpret changes in symptoms as reflecting response to treatment. However, changes in symptom functioning and the measurement of the underlying constructs may be reflected in reported change. Longitudinal measurement invariance (LMI) is a statistical approach that assesses the degree to which measures consistently capture the same construct over time.

Purpose: Using data from a randomized clinical trial evaluating cognitive behavioral therapy (CBT) for children with autism and co-occurring anxiety, this study examined the relationship between autism features and anxiety symptoms throughout CBT.

Methods: Two multilevel mediation analyses were run which examined the mediating role of changes in anxiety for changes in two core features of autism, (a) repetitive and restrictive behaviors (RRBs) and (b) social communication/interaction impairments, between pre- and post-treatment.

Results: Indirect effects between time and autism characteristics were significant for both models, indicating that as anxiety changes, so do RRBs and social communication/interaction as the outcomes respectively.

Background: Despite evidence for its efficacy, exposure therapy for anxiety is rarely used in routine care settings. Efforts to address one major barrier to its use - therapists' negative beliefs about exposure - have included therapist-level implementation strategies, such as training and consultation. Experiential training, in which therapists themselves undergo exposures, has recently demonstrated feasibility, acceptability and preliminary effectiveness for increasing exposure use.

Anger outbursts (AO) are associated with severe symptoms, impairment and poorer treatment outcomes for anxious children, though limited research has examined AO in youth with co-occurring autism and anxiety disorders. This study examined AO in children with autism and anxiety by evaluating clinical characteristics, family accommodation, and changes in AO following anxiety-focused treatment. The sample comprised 167 youth with autism and anxiety enrolled in a multi-site randomized clinical trial comparing standard care CBT for anxiety, CBT adapted for youth with autism, and usual care.

Purpose Of Review: We review (1) the empirical literature for cognitive behavioral therapy (CBT) for youth anxiety delivered in community settings, (2) the use of online delivery methods in this process, and (3) identified barriers and facilitators to implementation of CBT for youth anxiety in community mental health clinics (CMHCs). We provide suggestions for future work.

Recent Findings: Meta-analytic reviews of effectiveness studies suggest that outcomes comparable to those of efficacy studies can be achieved in community settings, particularly when in-session exposures occur.

Objective: To evaluate improvement during the (a) cognitive and (b) exposure therapy phases of cognitive-behavioral therapy (CBT) for autistic youth with anxiety disorders.

Method: Participants were 148 autistic youth (aged 7-13; 77% male; 64% White) with clinically significant anxiety who were randomized to standard or adapted CBT. Clinician-rated anxiety severity was recorded at each appointment.

Article Synopsis
  • The study focuses on creating and assessing the Modular Evidence-Based Practices for Youth with Autism Fidelity Scale (MEYA-FS) to improve the evaluation of treatment fidelity in cognitive-behavioral therapy for young people with autism.
  • Recorded sessions from 77 youths undergoing different therapy programs were analyzed, revealing that while adherence items showed good reliability, competence items had some inconsistencies.
  • Findings indicated that higher adherence and competence in treatment were linked to better clinical outcomes, supporting the scale's validity and usefulness in research related to autism interventions.
