- The aim of the present study was to evaluate the psychometric properties of the Competence and Adherence Scale for Cognitive Behavioral Therapy (CAS-CBT). The CAS-CBT is an 11-item scale developed to measure adherence and competence in cognitive-behavioral therapy (CBT) for anxiety disorders in youth. A total of 181 videotapes from the treatment sessions in a randomized controlled effectiveness trial (Wergeland et al., 2014) comprising youth (N = 182, M age = 11.5 years, SD = 2.1, range 8-15 years, 53% girls, 90.7% Caucasian) with mixed anxiety disorders were assessed with the CAS-CBT to investigate interitem correlations, internal consistency, and factor structure. Internal consistency was good (Cronbach's alpha = .87). Factor analysis suggested a 2-factor solution with Factor 1 representing CBT structure and session goals (explaining 46.9% of the variance) and Factor 2 representing process and relational skills (explaining 19.7% of the variance). The sum-score for adherence and competence was strongly intercorrelated, r = .79, p < .001. Novice raters (graduate psychology students) obtained satisfactory accuracy (ICC > .40, n = 10 videotapes) and also good to excellent interrater reliability when compared to expert raters (ICC = .83 for adherence and .64 for competence, n = 26 videotapes). High rater stability was also found (n = 15 videotapes). The findings suggest that the CAS-CBT is a reliable measure of adherence and competence in manualized CBT for anxiety disorders in youth. Further research is needed to investigate the validity of the scale and psychometric properties when used with other treatment programs, disorders and treatment formats.

- The present study investigated therapist adherence, therapist competence, and patient-therapist alliance as predictors of long-term outcomes of cognitive behavioral therapy (CBT) for anxiety disorders in youth. Potential differential effects for group versus individual CBT, for therapists with or without formal CBT training, and based on youth symptom severity were examined. Videotapes (n = 181) from treatment sessions in a randomized controlled effectiveness trial comprising youth (N = 170, M age = 11.6 years, SD = 2.1) with anxiety disorders were assessed for therapist adherence and competence. Alliance was rated by therapists and youth. Participants completed a diagnostic interview and an anxiety symptom measure at pre-treatment, post-treatment, one-year follow-up, and long-term follow-up (M = 3.9 years post-treatment, SD = 0.8, range = 2.2–5.9 years). The change in anxiety symptoms or diagnostic status from pre-treatment to long-term follow-up was not significantly related to any predictor variables. However, several interaction effects were found. For loss of principal diagnosis, therapist competence predicted positive outcome when therapist adherence also was high. Adherence was found to predict positive outcome if CBT was provided individually. Therapist-rated alliance was related to both loss of principal diagnosis and loss of all diagnoses when CBT was provided in groups. Interaction effects suggested that therapists displaying both high adherence and high competence produced better long-term outcomes. Further, the alliance may be particularly important for outcomes in group CBT, whereas adherence may be particularly important for outcomes in individual CBT.

- Objective The aim was to investigate whether clinical experience, formal cognitive behavioural therapy (CBT) training, adherence, and competence predict outcome in CBT for anxiety disorders in youth. Method Videotapes (N = 181) from the sessions in a randomized controlled effectiveness trial (Wergeland et al., 2014, Behaviour Research and Therapy, 57, 1-12) comprising youth (N = 182, M age = 11.5 years) with mixed anxiety disorders were assessed for treatment adherence and competence using the Competence and Adherence Scale for CBT for anxiety disorders in youth (Bjaastad et al., 2016, Psychological Assessment, 28, 908-916). Therapists' (N = 17) clinical experience and educational background were assessed. Participants completed a diagnostic interview (Anxiety Disorders Interview Schedule, child and parent versions) and an anxiety symptom measure (Spence Children's Anxiety Scale, child and parent versions) at pretreatment, posttreatment, and 1-year follow-up. Results Higher therapist adherence was related to better treatment outcomes, whereas number of years of clinical experience and competence was related to worse outcomes. However, these findings were not consistent across informants and the time points for the assessments. Interaction effects suggested that competence among therapists with formal CBT training was related to better patient outcomes. Conclusions Therapist adherence, competence, and clinical experience are associated with outcomes of manualized CBT for youth anxiety disorders, but mixed findings indicate the need for more research in this area.

- Objective: Conducted a randomized controlled trial to investigate the effectiveness of cognitive behavioral therapy (CBT), and compared the relative effectiveness of individual (ICBT) and group (GCBT) treatment approaches for anxiety disorders in children and adolescents.Methods: Referred youth (N = 182, M age = 11.5 years, range 8-15 years, 53% girls) with separation anxiety, social phobia, or generalized anxiety disorder were randomly assigned to ICBT, GCBT or a waitlist control (WLC) in community clinics. Pre-, post-, and one year follow-up assessments included youth and parent completed diagnostic interview and symptom measures. After comparing CBT (ICBT and GCBT combined) to WLC, ICBT and GCBT were compared along diagnostic recovery rates, clinically significant improvement, and symptom measures scores using traditional hypothesis tests, as well as statistical equivalence tests.Results: Significantly more youth lost all anxiety disorders after CBT compared to WLC. Full diagnostic recovery rate was 25.3% for ICBT and 20.5% in GCBT, which was not significantly different. There was continued lack of significant differences between ICBT and GCBT at one year follow-up. However, equivalence between GCBT and ICBT could only be demonstrated for clinical severity rating of the principal anxiety disorder and child reported anxiety symptoms post-treatment.Conclusion: Findings support the effectiveness of CBT compared to no intervention for youth with anxiety disorders, with no significant differences between ICBT and GCBT. However, the relatively low recovery rates highlight the need for further improvement of CBT programs and their transportability from university to community settings.

- A substantial number of children with anxiety disorders do not improve following cognitive behavioral therapy (CBT). Recent effectiveness studies have found poorer outcome for CBT programs than what is typically found in efficacy studies. The present study examined predictors of treatment outcome among 181 children (aged 8–15 years), with separation anxiety, social phobia, or generalized anxiety disorder, who participated in a randomized, controlled effectiveness trial of a 10-session CBT program in community clinics. Potential predictors included baseline demographic, child, and parent factors. Outcomes were as follows: a) remission from all inclusion anxiety disorders; b) remission from the primary anxiety disorder; and c) child- and parent-rated reduction of anxiety symptoms at post-treatment and at 1-year follow-up. The most consistent findings across outcome measures and informants were that child-rated anxiety symptoms, functional impairment, a primary diagnosis of social phobia or separation anxiety disorder, and parent internalizing symptoms predicted poorer outcome at post-treatment. Child-rated anxiety symptoms, lower family social class, lower pretreatment child motivation, and parent internalizing symptoms predicted poorer outcome at 1-year follow-up. These results suggest that anxious children with more severe problems, and children of parents with elevated internalizing symptom levels, may be in need of modified, additional, or alternative interventions to achieve a positive treatment outcome.
