Substance use outcomes from the Child/Adolescent Anxiety Multimodal Extended Long-term Study (CAMELS)

BACKGROUND

Substance use problems and anxiety disorders are both highly prevalent and frequently cooccur in youth. The present study examined the benefits of successful anxiety treatment at 3-12 years after treatment completion on substance use outcomes (i.e. diagnoses and lifetime expected use).

METHODS

The sample was from the Child/Adolescent Anxiety Multimodal Extended Long-term Study (CAMELS), a naturalistic follow-up study to the Child/Adolescent Anxiety Multimodal Study (CAMS) which randomized youth to cognitive behavioral therapy (CBT; Coping cat), medication (sertraline), their combination, or pill placebo. The first CAMELS visit occurred an average of 6.5 years following CAMS randomization. Participants were 319 youth (65.4% of the CAMS sample), aged 7-17 years at CAMS baseline assessment with a mean age of 17.6 years (range: 11-26 years) at the time of the first CAMELS follow-up. Substance use outcomes included diagnoses as well as lifetime substance use (i.e. alcohol and tobacco use).

RESULTS

Eleven of 319 (3.4%) CAMELS participants were diagnosed with a substance use disorder at the initial follow-up visit. When compared to the population lifetime rate of 11.4%, the rate of diagnoses in the posttreated sample was significantly lower. Additionally, rates of lifetime alcohol use were lower than population rates at the initial and final follow-up visits. Rates of lifetime tobacco use were similarly lower than lifetime population rates at the initial visit (driven by significantly lower rates in the CBT treatment condition), but higher by the final visit. Furthermore, treatment remission (but not treatment response) was associated with a lower rate of substance use diagnoses at the initial follow-up visit, although rates of lifetime alcohol and tobacco use did not differ by treatment outcome.

CONCLUSIONS

Anxiety treatments confer a beneficial impact on problematic substance use (i.e. diagnoses) as well as on expected substance use (i.e. alcohol and tobacco use) for on average, a period of 6.5 years.

Consultation as an Implementation Strategy to Increase Fidelity of Measurement-Based Care Delivery in Community Mental Health Settings: An Observational Study

Regularly administering outcome measures to clients to inform clinical decision making, referred to as measurement-based care (MBC), has the potential to improve mental health treatment due to its applicability across disorders and treatment settings. Given the utility of MBC, understanding predictors of high-fidelity MBC implementation is important. Training and consultation are widely used implementation strategies to increase the fidelity of evidence-based practice delivery but have rarely been studied with MBC. The current study will examine the relationship between time clinicians spent discussing a case in consultation ("dosage") and MBC fidelity. Thirty clinicians and 56 youth were in the MBC condition of a randomized controlled trial and completed baseline questionnaires. Consultation dosage was extracted from call notes. MBC fidelity was measured using the implementation index, which combines rates of administering and viewing questionnaires, using objective data from the online MBC system. Multi-level modeling was used. Greater consultation dosage significantly predicted a higher implementation index (ß = 0.27, SE = 0.06, p < .001). For every 30 min spent discussing a case in consultation, the case's MBC fidelity increased by 8.1%. Greater consultation dosage significantly predicted higher rates of administration (ß = 0.07, SE = 0.03, p = 0.033) and feedback report viewing (ß = 0.24, SE = 0.06, p < .001). More consultation at the case level predicts greater MBC fidelity using objective measures. The greatest impact was increasing the clinician feedback report viewing rate. The results of this study can help inform future efforts to increase the fidelity with which MBC is delivered and to make consultation as efficient and effective as possible.

External and Internal Validity Considerations in Youth Effectiveness Trials: Lessons Learned from the COMET Study

OBJECTIVE

Effectiveness trials aim to increase the generalizability and public health impact of interventions. However, challenges associated with this design present threats to external and internal validity. This paper illustrates these challenges using data from a two-site randomized effectiveness trial, the Community Study of Outcome Monitoring for Emotional Disorders in Teens (COMET) and presents recommendations for future research.

METHOD

COMET was a randomized effectiveness trial conducted in 19 community mental health clinics in two states comparing three interventions: treatment as usual (TAU), TAU with measurement-based care (TAU+), and the Unified Protocol forTransdiagnostic Treatment of Emotional Disorders in Adolescents with MBC (UPA). Participants included 176 clinicians (mean age = 35.5; 85.8% cisgender female; 53.0% racially and/or ethnically minorized) and 196 adolescents (mean age = 14.7; 65.3% cisgender female; 69.4% racially and/or ethnically minorized). Analyses outlined participant flow from recruitment to study completion, described participant characteristics, and examined site differences.

RESULTS

Analysis of participant flow suggested that recruitment and retention of clinicians and adolescents was challenging, raising questions about whether participants were representative of participating clinics. Both the clinician and adolescent samples were racially and ethnically diverse and adolescents were low income and clinically complex. Significant site differences were observed in clinician and adolescent characteristics.

CONCLUSIONS

While this study was successful in recruiting a diverse and historically under-represented sample, difficulties in recruitment and retention raise questions about external validity and site differences present challenges to internal validity of study findings. Suggestions for future effectiveness studies, drawing from implementation science approaches, are discussed.

Treatment Engagement in Adolescents: The Associations of Sociodemographic Characteristics, Caregiver Perceived Barriers, and Clinical Impairment

OBJECTIVE

To examine the associations between sociodemographic characteristics, perceived barriers to treatment, clinical impairment, and youth treatment engagement.

METHOD

Participants included 196 families (youth: ages 12 to 18; 64.3% cis-gender female; 23.5% Black, 60.7% White, and 12.2% Mixed/Other race; 41.3% Hispanic or Latinx ethnicity) recruited as part of a comparative effectiveness trial for adolescent anxiety and depression. Self-report measures of sociodemographic characteristics and caregiver perceived barriers were completed at intake. Youth clinical impairment was assessed at baseline via clinical interview. Measures of engagement were collected throughout treatment, including initiation status, session attendance, and termination status. Relationships were examined using analyses of variances and hierarchal linear and logistic modeling.

RESULTS

Perceived barriers did not differ by sociodemographic characteristics. Greater perceived stressors and obstacles predicted fewer sessions attended and a lower likelihood of successful termination. Youth of caregivers with an advanced degree and those with caregivers who were employed part time attended more sessions and were more likely to initiate and terminate treatment successfully compared to youth with caregivers of a lower education level or student or unemployed status. At higher levels of youth clinical impairment, greater perceived treatment demands and issues predicted reduced likelihood of treatment initiation.

CONCLUSIONS

Perceived barriers, sociodemographic characteristics, and clinical impairment were all associated with levels of engagement in the treatment process. Baseline and continued assessment of perceived and experienced barriers to treatment may promote individualized strategies for families identified as at-risk for reduced engagement.

Youth stress generation: an examination of the role of anxiety, anxiety symptoms and cognitive distortions

INTRODUCTION

Stress generation suggests a reciprocal relationship between depression and prospective stressful life events. However, the applicability of stress generation to anxiety disorders has been understudied, particularly among youth. We address this gap by examining stress generation in youth at high-risk of developing anxiety disorders.

METHODS

Participants were one-hundred thirty-six at-risk youth (M age = 8.69, 84.6% Caucasian; 55.9% female), each of whom had a parent with an anxiety disorder. We examined the role of an anxiety disorder diagnosis, anxiety symptoms, and cognitive distortions in youth's prospective one and six-year stressful life events (i.e., stress generation).

RESULTS

Anxiety symptoms and cognitive distortions were significant predictors of one-year total dependent stress. Anxiety diagnosis and anxiety symptoms were significant predictors of one-year dependent interpersonal stress. Anxiety diagnosis and anxiety symptoms were significant predictors of six-year independent stress.

CONCLUSION

Support for the stress generation model was found in high-risk youth, but only over a one-year period. This suggests important effects of anxiety and cognitive distortions on stress generation, though their implications might be time-capped.

Anxiety symptom trajectories from treatment to 5- to 12-year follow-up across childhood and adolescence

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. Using growth mixture modeling, the study identified distinct trajectories of anxiety across acute treatment (Weeks 0-12), posttreatment (Weeks 12-36), and the 4-year-long follow-up, and identified baseline predictors of these trajectories.

RESULTS

Three nonlinear anxiety trajectories emerged: "short-term responders" who showed rapid treatment response but had higher levels of anxiety during the extended follow-up; "durable responders" who sustained treatment gains; and "delayed remitters" who did not show an initial response to treatment, but showed low levels of anxiety during the maintenance and extended follow-up periods. Worse anxiety severity and better family functioning at baseline predicted membership in the delayed remitters group. Caregiver strain differentiated short-term responders from durable responders.

CONCLUSIONS

Findings suggest that initial response to treatment does not guarantee sustained treatment gains over time for some youth. Future follow-up studies that track treated youth across key developmental transitions and in the context of changing social environments are needed to inform best practices for the long-term management of anxiety.

Do youth anxiety measures assess the same construct consistently throughout treatment? Results are...complicated

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. We examined LMI in measures of anxiety severity/symptoms [i.e., Pediatric Anxiety Rating Scale (PARS), Multidimensional Anxiety Scale for Children (MASC), Screen for Child Anxiety and Related Disorders (SCARED)] in anxious youth at baseline and posttreatment. Initial fit was inadequate for 27 of 38 baseline and posttreatment models, but model modifications resulted in acceptable fit. Tests of LMI supported scalar invariance for the PARS and many, but not all, MASC and SCARED subscales. Findings suggest that the PARS, and many MASC and SCARED subscales can accurately be used to measure change over time, however, others may reflect changes in measurement properties.

Client-rated facilitators and barriers to long-term youth anxiety disorder recovery

OBJECTIVE

This study examined client ratings of 26 facilitators and barriers to anxiety improvement approximately 6 years after randomization to treatment for anxiety.

METHOD

319 youth (average 17.12 years old; 82.1% Caucasian; 58.6% female) participated in the longitudinal follow-up study to child and adolescent anxiety multimodal study (CAMS), a randomized controlled trial of medication, cognitive-behavioral therapy (CBT), combination, and placebo.

RESULTS

Correcting for multiple comparisons, CBT components (i.e., problem solving, changing unhelpful thoughts, relaxation skills) were rated significantly more helpful among youth without, versus with, an anxiety disorder at follow-up. Barriers that differentiated youth with and without an anxiety disorder included being bullied and difficulty applying therapy content to new situations. Comparisons between youth with different anxiety disorder trajectories (e.g., stable remission, relapsed, or chronically ill) also revealed several differences.

CONCLUSION

Findings suggest that client-rated facilitators and barriers covary with anxiety disorder recovery and may serve as useful tools when evaluating long-term treatment efficacy.

Characterizing measurement-based care implementation using therapist report

The effectiveness of measurement-based care (MBC), an evidence-based practice that uses regularly collected assessment data to guide clinical decision-making, is impacted by whether and how therapists use information from MBC tools in treatment. Improved characterization of how therapists use MBC in treatment sessions with youth is needed to guide implementation and understand variability in MBC effectiveness. To meet this need, this study examined therapists' sharing and discussion of MBC in treatment sessions. Thirty therapists were randomly assigned to the MBC condition as part of a comparative effectiveness trail of treatments for adolescent anxiety and depression. A qualitative content analysis was conducted on therapists' written explanations of changes made to the session based on the MBC data. Therapists reported sharing data with youth and caregivers in an average of 34.6% and 27.4% of sessions, respectively. Therapists reported incorporating MBC data in an average of 21.1% of sessions. When data were used, therapists predominately focused changes on short-term (e.g., current symptoms, treatment skill) rather than long-term (e.g., symptom progress, treatment goals) decision-making. Therapists inconsistently used MBC data, highlighting the need for improved training in and monitoring of how therapists use MBC in session to guide collaborative treatment decision-making with youth and caregivers.

Cost-Effectiveness Analysis of School-Based Treatments for Anxiety Disorders

BACKGROUND

School-based treatments for anxiety disorders are needed to address barriers to accessing community-based services. A key question for school administers are the costs related to these treatments.

AIMS OF THE STUDY

This study examined the cost-effectiveness of a school-based modular cognitive behavioral therapy (M-CBT) for pediatric anxiety disorders compared to school-based treatment as usual (TAU).

METHODS

Sixty-two school-based clinicians in Maryland and Connecticut were randomized (37 in CBT; 25 in TAU), trained, and enrolled at least one anxious student (148 students in CBT; 68 in TAU). Students (N = 216) were ages 6-18 (mean age 10.9); 63.9% were non-Hispanic White race-ethnicity; and 48.6% were female. Independent evaluators (IEs) assessed outcomes at post treatment and at a one-year follow up. Anxiety related costs included mental health care expenses and the opportunity costs of added caregiver time and missed school days.

RESULTS

The overall M-CBT ICER value of $6917/QALY reflected both lower costs for days absent from school (mean difference: $--117 per youth; p = 0.045) but also lower QALY ratings (mean difference: -0.024; p = 0.900) compared with usual school counseling. Among youth with more severe anxiety at baseline, M-CBT had a more favorable ICER ($-22,846/QALY). Other mental health care costs were similar between groups (mean difference: $-90 per youth; p = 0.328).

DISCUSSION

Although training school clinicians in M-CBT resulted in lower costs for school absences, evidence for the cost effectiveness of a modular CBT relative to existing school treatment for pediatric anxiety disorders was not robustly supported. Findings suggest school-based M-CBT is most cost effective for youth with the highest levels of anxiety severity and that M-CBT could help reduce the costs of missed school. Interpretations are limited due to use of retrospective recall, lack of data on medication use, and small sample size.

IMPLICATIONS FOR HEALTH CARE PROVISION AND USE

Schools may benefit from providing specialized school-based services such as M-CBT for students with the highest levels of anxiety.

IMPLICATIONS FOR HEALTH POLICIES

Investment decisions by schools should take into account lower costs (related to school absences), the costs of training clinicians, and student access to CBT in the community.

IMPLICATIONS FOR FURTHER RESEARCH

Replication with a larger sample, service use diaries, and objective school and medical records over a longer period of time is warranted.

WHO Participates in Effectiveness Research? A Comparison of Effectiveness Trial Clinicians to National Survey Samples

Findings from research participants in effectiveness treatment trials (i.e., randomized control trials conducted in community rather than research settings) are considered more generalizable than those from participants in efficacy trials. This is especially true for clinician participants, whose characteristics like attitudes towards evidence-based practices (EBPs) may impact treatment implementation and the generalizability of research findings from effectiveness studies. This study compared background characteristics, attitudes toward EBPs, and attitudes towards measurement-based care (MBC) among clinicians participating in a National Institute of Mental-Health (NIMH) funded effectiveness trial, the Community Study of Outcome Monitoring for Emotional Disorders in Teens (COMET), to clinician data from nationally representative U.S. survey samples. Results indicated COMET clinicians were significantly younger, less clinically experienced, and were more likely to have a training background in psychology versus other disciplines compared to national survey samples. After controlling for demographics and professional characteristics, COMET clinicians held more positive attitudes towards EBPs and MBC compared to national survey samples. Implications for implementation efforts are discussed.

Cost-benefit Analysis of the Coping and Promoting Strength Program

This study sought to estimate the net benefits and return on investment (ROI, %) of the Coping and Promoting Strength (CAPS) program to families and insurers, respectively, using data from a multi-year follow up of 136 US families who had participated in a randomized efficacy trial of CAPS. CAPS is a brief parent-focused psychosocial intervention that was compared to information monitoring in the trial. Of the 136 original participants, 113 (83%) completed follow-up interviews 7.1 years, on average, after the CAPS study baseline (mean follow-up age: 15.8 years; range: 13.1 to 20.8 years). Parent-reported willingness-to-pay values and estimates of behavioral healthcare cost savings from delayed onset of anxiety were used to simulate the average net benefits of CAPS to families and insurance plans, respectively, assuming patients pay 20% coinsurance. Psychologists in private offices were expected to charge an average of approximately $195 per CAPS session or $1417 in total in 2020 dollars. The estimated family share of the total CAPS session cost was $283 per youth, while the insurer share was $1134 per youth. Given these costs, the CAPS intervention was estimated to result in average overall net benefits of $1033 per youth (95% CI: -$546 to $2611). Families gained $344 (95% CI: $232 to $455 per family) for an ROI of 121%. Insurance plans on average gained a net savings of $689 per youth (95% CI: -$778 to $2156 per youth) for an average ROI of 61%. In this multiyear follow-up of offspring of anxious parents, exposure to the CAPS pediatric anxiety prevention program was found to be more economically efficient than was waiting for an anxiety disorder to be diagnosed. ClinicalTrials.gov Identifier: NCT00847561.

Preventing the Onset of Anxiety Disorders in Offspring of Anxious Parents: A Six-Year Follow-up

This study examined the effects of a family-based intervention Coping and Promoting Strength (CAPS) relative to a control condition, information-monitoring (IM), to prevent the onset of anxiety disorders in offspring of anxious parents six years after their initial assessment. One hundred thirty six families participated in the original randomized trial; 113 (83%) completed the one time follow-up assessment. Presence of anxiety disorders and severity of symptoms in offspring were assessed by masked evaluators using the Anxiety Disorders Interview Schedule; parents and offspring also completed questionnaires assessing offspring anxiety. Using the intention to treat sample from the original trial, Cox regression models showed significant intervention main effects in the rate of onset of anxiety disorders from baseline to follow-up (anxiety disorder: hazard ratio (HR) = 2.55, 95% CI: 1.54, 4.21) but growth curves suggest effects occurred within the first year after program completion. No group differences were found in the cumulative incidence of anxiety disorders at the six-year follow-up. Additional intervention appears needed to maintain the initial positive effects long-term to reduce the risk for downstream disability.Clinical Trials Registration: NCT00847561.

Harnessing Home-School Partnerships and School Consultation to Support Youth With Anxiety

Youth with anxiety often experience significant impairment in the school setting. Despite the relevance and promise of addressing anxiety in schools, traditional treatment approaches to school-based anxiety often do not adequately address generalization to the school setting, or they require removing the student from the classroom to deliver time- and staff-intensive programs. Such programs often leave teachers and caregivers feeling ill-equipped to support the student with anxiety throughout the natural course of the school day. Given the heavy demands placed on teachers and documented burnout among school professionals, providing effective school supports requires collaborative partnerships among outpatient therapists/specialists, school personnel, and caregivers. Drawing from literature on collaborative models for externalizing problems, we offer recommendations for outpatient therapists and specialists working to implement evidence-based supports in school settings and promote home-school partnerships to benefit youth with anxiety in the school setting. Our recommendations touch upon several components of such school consultation, including (a) identification of key parties involved, (b) conducting a needs assessment, (c) collaborative goal setting and development of a fear hierarchy, (d) plan development and implementation (e.g., facilitating a school-based exposure mindset, promoting home-school communication, enhancing school relationships), and (e) progress monitoring and ongoing support. We conclude with a case example to bring these recommendations to life.

Impact of treatment improvement on long-term anxiety: Results from CAMS and CAMELS

OBJECTIVE

This article examined associations between change in youth and family characteristics during youth anxiety treatment and long-term anxiety severity and overall functioning.

METHOD

Participants (N = 488; age 7-17 years; 45% male; 82% white) were randomized to 12 weeks of cognitive behavioral therapy (Coping Cat), medication (sertraline), their combination, or pill placebo in the Child/Adolescent Anxiety Multimodal Study (CAMS). A subset participated in the naturalistic follow-up Child/Adolescent Anxiety Multimodal Extended Long-term Study (CAMELS; n = 319; 3.70-11.83 years post-treatment). The current secondary analyses examined how change in anxiety severity (Child Global Impression-Severity), overall functioning (Children's Global Assessment Scale), caregiver psychopathology (Brief Symptom Inventory), caregiver strain (Family Burden Assessment Scale), and family dysfunction (Brief Family Assessment Measure) during CAMS was associated with anxiety severity and overall functioning years later (M = 7.72 years). CAMS procedures were registered on clinialtrials.gov.

RESULTS

Improvements in factors related to functioning (i.e., overall functioning, family dysfunction, caregiver strain) were associated with improvements in anxiety severity in CAMELS (|βys| ≥ .04, ps ≤ .04). Improvements in factors related to psychopathology (i.e., anxiety severity, caregiver psychopathology) were associated with improvements in overall functioning in CAMELS (|βys| ≥ .23, ps ≤ .04). It was changes in each of the variables examined (rather than baseline values) that predicted anxiety severity and overall functioning.

CONCLUSIONS

Both youth and family factors play a significant role in long-term treatment outcomes. Therapists would be wise to monitor how these factors change throughout treatment. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Antidepressant Use in a 3- to 12-Year Follow-up of Anxious Youth: Results from the CAMELS Trial

The current study explored whether patient characteristics predicted patterns of antidepressant use (i.e., never used, single episode of use, or two or more episodes) in a naturalistic follow-up. Participants in the child/adolescent multimodal (CAMS) extended long-term study. (n = 318) indicated medication use over the course of eight follow-up visits, 3-12 years after receiving treatment in CAMS. 40.6% of participants reported never using an antidepressant during follow-up, 41.4% reported a single episode of antidepressant use, and 18.0% reported multiple episodes of antidepressant use. Greater baseline anxiety severity marginally predicted a single episode of antidepressant use; baseline depression severity predicted multiple episodes of use. Reasons for discontinuing antidepressants included perceived ineffectiveness (31.8%), side effects (25.5%), and improvement in symptoms (18.5%). Exploratory analyses examined predictors of medication use. Findings suggest that antidepressant use is common among anxious youth, as is discontinuation of antidepressant use. Clinical implications and future directions are discussed.

Negative Life Events as Predictors of Anxiety Outcomes: An Examination of Event Type

Long-term follow-up studies of anxiety treatment have found that greater exposure to negative life events (NLEs) predicts poorer anxiety outcomes, but none have examined whether specific types of NLEs are differentially associated with child outcomes. This study examined the frequency of NLEs and whether specific types of NLEs were associated with increased risk of having an anxiety disorder 6.5 years post randomization. Participants were 319 adolescents and adults, ages 11 to 26 (M = 17), enrolled in Child/Adolescent Anxiety Multimodal Extended Long-term Study. At their first follow-up visit, participants completed a diagnostic interview and a 40-item Life Events Scale that reflected whether specific events occurred since their last post treatment assessment. Life events were categorized into domains (i.e., family, academic, health, and social) via researcher consensus. Participants reported having experienced an average of four NLEs. Participants with an anxiety disorder at follow-up were significantly more likely to have failed a grade in school (OR = 5.9) and experienced a negative change in acceptance by peers (OR = 4.9; ps < 0.001). After controlling for gender, age, race, and SES, a greater number of NLEs in the academic domain increased the odds of having an anxiety disorder at follow-up (OR = 2.4, p < 0.001). No other domains were predictive of disorder status at follow-up. Findings highlight the value of examining specific NLEs in relation to the long-term child anxiety outcomes.

Intervention Adherence and Self-Efficacy as Predictors of Child Outcomes in School Nurse-Delivered Interventions for Anxiety

This study examined the association between two implementation factors, nurse-reported intervention adherence and self-efficacy, and children's outcomes in school nurse-delivered anxiety interventions. Data were collected in a pilot randomized controlled effectiveness trial with 54 children and 21 school nurses. Nurses implemented either a cognitive behavioral or relaxation-skills-only intervention. Nurse questionnaires assessed implementation factors. Independent evaluators assessed changes in children's anxiety symptoms at postintervention and at 3-month follow-up using clinical improvement and global functioning scales. Regression analyses indicated that greater intervention adherence was associated with greater anxiety symptom improvement at follow-up. Nurse self-efficacy interacted with intervention group, such that nurses with higher self-efficacy who implemented the cognitive behavioral intervention tended to have children show improvement and higher postintervention functioning. The impact of implementation factors on children's outcomes may differ depending on intervention type. Self-efficacy may be important for nurses using relatively complex interventions. Intervention adherence should be supported through training and consultation.

School-Based Treatment for Anxiety Research Study (STARS): a Randomized Controlled Effectiveness Trial

The current study compared the effectiveness of a school-clinician administered cognitive behavioral treatment (CBT) to treatment as usual (TAU) at post-treatment (i.e., after 12 weeks) and at a 1 year follow-up. Sixty-two school-based clinicians (37 in CBT; 25 in TAU) and 216 students (148 students in CBT; 68 in TAU) participated. Students were ages 6-18 (mean age 10.87; 64% Caucasian & 29% African American; 48.6% female) and all met DSM-IV diagnostic criteria for a primary anxiety disorder. Independent evaluators (IEs) assessed clinical improvement, global functioning, and loss of anxiety diagnoses; children and parents completed measures of anxiety symptoms. At post-treatment, no significant treatment main effects emerged on the primary outcome; 42% and 37% of youth were classified as treatment responders in CBT and TAU respectively. However, parent-report of child anxiety showed greater improvements in CBT relative to TAU (d = .29). Moderation analyses at post-treatment indicated that older youth, those with social phobia and more severe anxiety at baseline were more likely to be treatment responders in CBT compared to TAU. At the 1 year follow-up, treatment gains were maintained but no treatment group differences or moderators emerged. CBT and TAU for pediatric anxiety disorders, when delivered by school clinicians were generally similar in effectiveness for lowering anxiety and improving functioning at both post-treatment (on all but the parent measure and for specific subgroups) and 1 year follow-up. Implications for disseminating CBT in the school setting are discussed.

Mediators of youth anxiety outcomes 3 to 12 years after treatment

OBJECTIVE

Test changes in perceived coping efficacy, negative self-statements, and interpretive biases to threat during treatment as potential mediators of the relationship between randomly assigned treatment conditions and long-term anxiety follow-ups. Age at randomization was also tested as a moderator of mediational relationships.

METHOD

Participants included 319 youth (ages 7-17) from the Child/Adolescent Multimodal Study (CAMS) who participated in a naturalistic follow-up beginning an average of 6.5 years after the end of the CAMS intervention. The intervention conditions included cognitive behavioral therapy (CBT; Coping Cat), pharmacotherapy (sertraline), combined CBT and sertraline, and pill placebo. Putative mediators were measured four times during the intervention phase. Follow-up consisted of four annual assessments of current anxiety.

RESULTS

Reductions on a measure of interpretive bias to threat over the course of the combined condition intervention, as compared to the placebo condition, mediated anxiety outcomes at the first follow-up visit. This mediated effect was not significant for the CBT-only or sertraline-only conditions when compared to the placebo condition. No other significant mediated effects were found for putative mediators. Age did not significantly moderate any mediated effects.

CONCLUSION

Changes in youth-reported interpretive biases to threat over the course of combined youth anxiety interventions, as compared to a placebo intervention, may be associated with lower anxiety an average of 6.5 years following treatment.

Longitudinal Study of Sleep and Internalizing Problems in Youth Treated for Pediatric Anxiety Disorders

The current study examined prospective bidirectional links between dysregulated sleep, and anxiety and depression severity across 4 years, among youth with a history of anxiety disorder. Participants were 319 youth (age 11-26 years), who previously participated in a large multisite randomized controlled trial for the treatment of pediatric anxiety disorders, Child/Adolescent Anxiety Multimodal Study (CAMS), and subsequently enrolled in a naturalistic follow-up, Child/Adolescent Anxiety Multimodal Extended Long-term Study (CAMELS), an average of 6.5 years later. They participated in four annual visits that included self-report items of dysregulated sleep and semi-structured multi-informant interviews of anxiety and depression. Dysregulated sleep was bidirectionally associated with clinician-rated anxiety and depression symptom severity across adolescence and young adulthood. However, these bidirectional relationships were attributable to youth mean levels of dysregulated sleep, and anxiety and depression severity over the 4 years. Elevations in dysregulated sleep at each visit, relative to mean levels, did not predict worse anxiety or depression severity 1 year later. Likewise visit-specific elevations in anxiety and depression severity, as opposed to average levels, did not predict higher levels of dysregulated sleep at the next visit. Having higher levels of dysregulated sleep or more severe internalizing problems across the four-year period, as opposed to reporting a relative increase in symptom severity at a particular visit, posed greater risk for poor mental health. Interventions should continue to assess and treat persistent sleep problems alongside anxiety and depression.

Teacher Anxiety Program for Elementary Students (TAPES): intervention development and proposed randomized controlled trial

Background

Excessive student anxiety is a common problem that severely impairs short- and long-term academic functioning and increases teacher burden. Reducing student anxiety has been associated with improvement in educational functioning. Because anxiety manifests daily in the classroom, teachers are in an ideal position to identify and help students manage their anxiety. Unfortunately, teachers lack the knowledge and skills to support the learning of students with excessive anxiety. The Teacher Anxiety Program for Elementary Students (TAPES), a novel teacher-administered school-home collaborative intervention, was designed to address this gap.

Methods

This manuscript describes the protocol for developing and evaluating TAPES. Specifically, we present a description of: (1) the intervention and theoretical model; and (2) methods for the proposed randomized controlled trial comparing TAPES to a standard professional development seminar focused on reducing student anxiety.

Discussion

Primary aims examine the impact of the TAPES training on teacher knowledge and skill. Secondary aims examine the impact of TAPES on student outcomes. Exploratory aims will examine mediators based on our proposed theory of change. If effective, TAPES has the potential to directly benefit teachers (improving skills) and students (reducing anxiety and improving functioning).

The Effects of Youth Anxiety Treatment on School Impairment: Differential Outcomes Across CBT, Sertraline, and their Combination

Youth anxiety disorders are highly prevalent and are associated with considerable school impairment. Despite the identification of well-supported strategies for treating youth anxiety, research has yet to evaluate the differential effects of these treatments on anxiety-related school impairment. The present study leveraged data from the Child/Adolescent Anxiety Multimodal Study to examine differential treatment effects of CBT, sertraline, and their combination (COMB), relative to placebo (PBO), on anxiety-related school impairment among youth (N = 488). Latent growth modeling revealed that all three active treatments demonstrated superiority over PBO in reducing anxiety-related school impairment over time, with COMB showing the most robust effects. According to parent report, medication strategies may have stronger effects on anxiety-related school impairment among males than among females. Results were discrepant across parents and youth. Findings are discussed in terms of clinical implications for anxious youth and the need for continued research to examine treatment effects on anxiety-related school impairment.

170Lipoprotein subclasses associated with high-risk coronary atherosclerotic plaque: insights from the PROMISE clinical trial

Background

Greater than half of major adverse cardiovascular events (MACE) occur in individuals with non-obstructive coronary artery disease (CAD) and may be related to the presence of high-risk coronary atherosclerotic plaque (HRP). HRP can be detected by coronary computed tomographic angiography (CTA) and is associated with increased MACE risk. Biomarkers associated with HRP may therefore aid in risk stratification in individuals with chest pain and provide insight into the biology of HRP.

Purpose

To determine whether nuclear magnetic resonance (NMR)-measured lipoprotein particles are associated with HRP independent of risk factors.

Methods

This study included 1755 stable symptomatic outpatients enrolled in the PROMISE trial who had coronary CTA performed. Thirty-seven lipoprotein particle parameters were measured in plasma using NMR. Principal components analysis was used to reduce the number of correlated lipoproteins into a smaller number of uncorrelated factors. HRP cases (N=277) were defined as presence of HRP features (positive remodeling, low CT attenuation or napkin-ring sign) with or without obstructive CAD; controls had no HRP and no obstructive CAD (N=1478). Multivariable logistic regression models adjusting for age, sex, diabetes, hypertension, BMI, smoking status and statin use were used to test for association of lipoprotein factors with HRP case/control status; lipoproteins loaded within significant factors (p<0.05) were tested individually. Finally, because event rates in PROMISE were too low, we used a separate study (CATHGEN, a study of individuals undergoing coronary angiography; N=8707) to test for association of lipoproteins with MACE using multivariable Cox proportional hazard models.

Results

HRP cases were less likely to be female than controls (36.8% vs. 56.6%) and were more likely to have diabetes (23.5% vs 19.6%), but were of similar age (60.1 vs 60.4 years [SD±8]) and with similar statin use (45.2% vs 44.4%). In multivariable models, two lipoprotein factors were associated with HRP: an HDL factor (OR 1.29 [95% CI, 1.10–1.52], p=0.002) and a triglyceride (TG) factor (OR 1.19 [1.03–1.36], p=0.01). Within these two factors, H6P (a large HDL subclass; OR 0.67 [0.54–0.82], p<0.001), HDL size (OR 0.78 [0.66–0.92], p=0.003) and small TG-rich lipoproteins (OR 1.22 [1.07–1.39], p=0.002) were associated with HRP. H6P (HR 1.1 [1.07–1.13], p<0.0001) and HDL size (HR 1.28 [1.24–1.32], p<0.0001) were also associated with time to death or MI in CATHGEN, but in the opposite direction.

Conclusions

In a cohort of low-risk patients from the PROMISE trial, large HDL and small TG particles were associated with CTA-defined HRP independent of risk factors. Large HDL particles were also associated with incident MACE in a separate high-risk cohort. The discordant direction of association of HDL subclasses with HRP and MACE is likely due to underlying HDL biology and requires further study.

Mood and suicidality outcomes 3-11 years following pediatric anxiety disorder treatment

BACKGROUND

Youth anxiety interventions have potential to reduce risk for depression and suicidality.

METHODS

This naturalistic follow-up of the multi-site, comparative treatment trial, inking and behavior, and depressive symptoms 3-11 years (mean 6.25 years) following 12-week evidence-based youth anxiety treatment. Participants (N = 319; 10-26 years, mean 17 years) completed semiannual questionnaires and annual diagnostic interviews for 4 years.

RESULTS

One-fifth (20.4%) of the sample met DSM-IV criteria for a mood disorder, 32.1% endorsed suicidal ideation, and 8.2% reported suicidal behavior. Latent class growth analysis yielded two linear trajectories of depressive symptoms, and 85% of the sample demonstrated a persistent low-symptom course over seven assessments. Child/Adolescent Anxiety Multimodal Study (CAMS) 12-week treatment outcome (positive response, remission) and treatment condition (cognitive behavior therapy [CBT], medication, CBT + medication, pill placebo) were not associated with subsequent mood disorder or suicidal thinking. CAMS remission predicted absence of suicidal behavior, and treatment response and remission predicted low depressive symptom trajectory. Greater baseline self-reported depressive symptoms predicted all long-term mood outcomes, and more negative life events predicted subsequent mood disorder, depressive symptom trajectory, and suicidal ideation.

CONCLUSIONS

Effective early treatment of youth anxiety, including CBT, medication, or CBT + medication, reduces risk for subsequent chronic depressive symptoms and suicidal behavior. Attention to (sub)clinical depressive symptoms and management of negative life events may reduce odds of developing a mood disorder, chronic depressive symptoms, and suicidality. Findings contribute to evidence that early intervention for a primary disorder can serve as secondary prevention.
