Adherence, Competence, and Alliance as Predictors of Long-term Outcomes of Cognitive Behavioral Therapy for Youth Anxiety Disorders
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.publishedVersio
Development and feasibility testing of a physical activity intervention for youth with anxiety and depression : a study protocol
Background: Anxiety and depressive disorders in children and adolescents are highly prevalent and account for more than half of all youth psychiatric disorders. Left untreated, anxiety, and depression lead to numerous detrimental outcomes, including reduced quality of life, psychiatric, and somatic comorbidity and even reduced lifespan. This puts a large strain on child and adolescent mental healthcare services (CAMHS) to provide effective treatments. However, even when provided the best evidence-based treatment, between 40–50% of patients continue to report significant symptom burdens. Thus, there is an immediate need for supplemental and/or new treatment approaches. Physical activity as a supplementary treatment may be such an approach. However, research investigating this approach within this population is scant. This protocol paper describes the development and feasibility trial of a physical activity-based intervention targeting anxiety and depressive symptoms in youth treated in CAMHS. Methods/design: The study is based on the UK Medical Council Research Framework (MRC) for developing and evaluating complex interventions. Feasibility and acceptability of the physical activity intervention (confident, active, and happy youth) will be evaluated in an uncontrolled open-label trial using qualitative and quantitative data. Twenty youths with anxiety and/or depressive symptoms will be recruited. Acceptability of assessment procedures, the intervention, and perceived benefits and barriers to participation will be assessed, and qualitative interviews with participants, caregivers, and referring specialists will explore contextual and practical factors associated with intervention delivery. Physical activity will be measured using the Actigraph GT3X+ monitor at baseline, and post-intervention and change in anxiety and depression will be assessed. Discussion: This study will contribute to the development of supplementary physical treatment interventions for youth with anxiety and depression in contact with CAMHS. The goal is to examine new avenues of treatment that ultimately may improve upon current treatment outcomes of anxiety and depression. This work will be in preparation for a future definitive randomized controlled trial (RCT) of this approach, in line with the MRC Framework. Trial registration: ClnicalTrials.gov, NCT05049759.

Feasibility of a physical activity intervention for children and adolescents with anxiety and depression
Background Physical activity is identified as a key modifiable factor towards good short- and long-term mental health and has shown positive effects on anxiety and depression in children and adolescents. However, physical activity-based interventions are not a part of standard mental health care and evidence on the effect of such interventions is still lacking. A transdiagnostic, physical activity-based intervention was developed as a supplement to routine clinical care for youth in specialized child and adolescent mental health services. Methods /design. The feasibility of the physical activity intervention (Confident, Active, and Happy Youth) was evaluated in an open-label study by assessing the recruitment process, acceptability, intervention suitability, contentment, and preliminary intervention effects in the form of youth and parent-rated anxiety and depressive symptoms. Physical activity levels were objectively measured using Actigraphâ„¢ physical activity sensors, and progression to a definitive study was evaluated in accordance with a priori criteria. Results In total 21 of 25 eligible youth consented to participate, two dropped out of the intervention and 19 completed (76% of eligible participants). The retention rate among consenting participants was 89% and mean attendance to sessions was 83%. The suitability of the intervention was rated as good by the youth and their parents, and intervention contentment was rated high. Changes in youth and parent-rated symptom measures following the intervention were negligible, except for parent-rated anxiety symptoms assessed at 10-month follow-up. Accelerometer data indicated lower levels of moderate to vigorous activity during sessions than intended. No adverse effects were noted. Conclusion This feasibility study met the pre-determined progression criteria to a definitive study. Thus, a larger trial with longer follow-up should be conducted to explore the effect of the intervention. Trial registration ClnicalTrials.gov, NCT05049759. Retrospectively registered, 20.09.2021
Long-term effectiveness of cognitive behavior therapy for youth with anxiety disorders: Outcome, predictors and social anxiety
Cognitive behavioral therapy (CBT) has demonstrated favorable long-term outcomes in youth with anxiety disorders in efficacy trials. However, long-term outcomes of CBT delivered in a community setting are uncertain. The aim of study presented in this thesis was to examine the long-term effectiveness of CBT for youth with mixed anxiety disorders treated in community mental health clinics. In addition, potential predictors of long-term outcomes were assessed, and subtypes of social anxiety disorder were investigated. The thesis consists of three papers presenting findings of this study. Data stem from a randomized controlled trial examining the effectiveness of CBT for youth with anxiety disorders treated in seven participating community mental health clinics in Western Norway. A total of 139 youth (mean age at assessment 15.5 years, range 11– 21 years) with a principal diagnosis of separation anxiety disorder (SAD), social anxiety disorder (SOP), and/or generalized anxiety disorder (GAD) were evaluated, on average, 3.9 years post-treatment (range 2.2–5.9 years). Long-term outcome was defined as loss of all inclusion anxiety disorders, loss of the principal inclusion anxiety diagnosis, and changes in youth- and parent-rated youth anxiety and depressive symptoms. Paper I examined the long-term outcomes of individual (ICBT) and group CBT (GCBT) using multilevel modeling and equivalence testing. Paper II assessed predictors of long-term outcomes using multilevel modeling. Paper III investigated pre-treatment subtypes of SOP in youth with the disorder drawn from the original sample, using exploratory factor analyses. In Paper I, results demonstrated loss of all inclusion anxiety disorders in 53% of participants, loss of the principal anxiety diagnosis in 63%, as well as significant reductions in all youth- and parent-rated youth anxiety and depression symptom measures at long-term follow-up. No significant differences in outcome were identified between ICBT and GCBT, and equivalency was partially established. Significant symptom reductions were found between pre-treatment and long-term follow-up, although participants with a principal diagnosis of SOP had lower odds for recovery, compared to those with a principal diagnosis of SAD or GAD. In Paper II, the study identified low family social class as the most stable predictor of poorer outcomes. High treatment motivation was associated with better outcomes, whereas a diagnosis of SOP was associated with worse outcomes, including when analyses were controlled for other predictors. Recovery from the principal anxiety disorder at post-treatment was associated with better outcomes at long-term follow-up. In Paper III, the study identified three distinct subtypes of SOP, labelled performance, observation, and interaction. Exploratory factor analyses of avoidance responses showed these were best represented by one avoidance factor. Few youth qualified exclusively for any of the fear subtypes, thus calling into question the clinical utility of these subtypes. Nevertheless, the findings indicate distinct contributions of fear and avoidance in SOP presentation. In conclusion, the findings support the long-term effectiveness of ICBT and GCBT for youth with mixed anxiety disorders treated in community clinics. Few pretreatment predictors were associated with long-term outcomes, although low family social class and a diagnosis of SOP were associated with poorer outcomes. High treatment motivation was associated with better outcomes. Subtypes of SOP were identifiable and differed from avoidance-based subtypes. The clinical implications of the findings are that CBT treatment for youth anxiety can be disseminated to community clinics and delivered in both individual and group formats, providing improvement rates almost on par with those in efficacy studies. Careful assessment at pre-treatment may help to identify youth who need augmented or more specific treatment, i.e., youth with SOP. It is questionable if subtypes of SOP are of clinical utility, although targeting of specific fear domains may enhance treatment
Subtyping social anxiety in youth
Few empirical studies have examined subtypes of social anxiety disorder (SAD) in youth, and limited consensus resides on the nature of potential subtypes. Identifying subtypes, based on both fear and avoidance patterns, can help improve assessment and treatment of SAD. Subtypes of fear and avoidance were examined in a sample comprising 131 youth (age 8–15 years) diagnosed with SAD using the Anxiety Disorders Interview Schedule for children and parents (ADIS-C/P). Exploratory factor analysis of fear responses revealed three factors, defining fear subtypes linked to: (1) performance, (2) observation, and (3) interaction situations, respectively. Exploratory factor analysis of avoidance responses showed these were best represented by one avoidance factor. Few youth qualified exclusively for either of the fear subtypes, thus calling into question the clinical utility of these subtypes. Nevertheless, the findings indicate distinct contributions of fear and avoidance in SAD presentation. This finding might help clinicians target and improve treatment of the disorder

Treatment motivation in child anxiety treatment – Factor structure and associations with outcomes
Motivation is associated with cognitive behavioral treatment (CBT) outcomes. We examined the factor structure of a motivation measure, and if motivation factors were differentially associated with CBT outcomes for children with anxiety. The sample comprised 179 children aged 8–15 years (M age = 11.5 years, SD = 2.1; 53.0% girls) with anxiety disorders who received CBT in a randomized controlled community clinic trial. Participants completed the Nijmegen Motivation List – child version (NML-C) at treatment onset. Outcomes were diagnostic recovery, anxiety/depression symptom and clinical severity change from pre-treatment to post-treatment, one-, and 3.9-years follow-up, and treatment dropout. Principal component analysis showed that the NML-C comprised two factors, preparedness (beliefs that CBT is useful and willingness to engage in treatment; 36.4% explained variance) and distress (discomfort from symptoms and perceived urgency to be helped; 12.7% explained variance). Higher preparedness predicted larger clinical severity reduction at post-treatment, alongside pre-treatment clinical severity. Higher distress predicted larger depression reduction at one-year follow-up, alongside pre-treatment depression. Higher preparedness predicted lower dropout. In conclusion, the NML-C comprises two factors that are differentially associated with CBT outcomes, but not above the effects of pre-treatment symptoms. Clinicians' focus on children's distress and preparedness could enhance CBT outcomes and reduce dropout
