Treatment Fidelity in Brief Versus Standard-Length School-Based Interventions for Youth with Anxiety

To examine treatment fidelity in a randomized controlled trial of indicated school-based cognitive-behavioral therapy (CBT) delivered in groups to youth with anxiety. We investigated whether adherence and competence (a) differed across brief and standard-length CBT, and (b) if adherence and competence predicted change in anxiety symptoms and impairment. Method: Sessions were observationally coded with the Competence and Adherence Scale for CBT for Anxiety Disorders in Youth. Coders (N = 7) rated 104 sessions from 52 groups delivered by 32 facilitators (M age = 43.2 years, SD = 8.1) to 295 youth (M age = 14.0 years, SD = 0.8). Outcomes were youth- and parent-reported anxiety symptoms and impairment at post-intervention and 1-year follow-up. Linear mixed effect models were used to analyze whether fidelity predicted clinical outcomes. Results: Levels of adherence and competence were adequate in both programs, but higher in brief compared to standard-length CBT p < .001 and p = .010, respectively). Neither adherence nor competence predicted clinical outcomes at any timepoints. Conclusion: Higher levels of adherence and competence in brief CBT suggest that it may be easier for novice CBT providers to achieve fidelity in simplified and less flexible interventions. Contrary to expectation, adherence and competence did not predict clinical outcomes.

A Randomized Controlled Trial of a Cognitive Behavior Therapy Program for Children with Clinical Anxiety Symptoms

High anxiety and anxiety disorders are among the most prevalent mental health problems in children and lead to significant interference with children’s daily functioning. Most empirical evaluations of treatment come from English-language countries. The aim of the present study was to evaluate and replicate the effectiveness of a cognitive-behavioral intervention program to manage anxiety in children among children from Greece. Forty-one children–parent(s) dyads participated in the study. Children were 9–12 years old, with clinically elevated symptoms of anxiety, and they were assigned to either the standard group treatment (cognitive behavior therapy (CBT)) or to a waitlist group (WL). Both children and their parents in the CBT group reported statistically significant reductions in children’s anxiety symptoms at post-intervention and at the 6-month follow-up. A significant reduction was also found in life interference due to anxiety according to both child and parent reports. In contrast, no significant changes in anxiety symptoms or life interference were reported among the WL. The current results support the effectiveness of a CBT program for anxious children from a non-clinic, non-school setting in Greece.
