Sleep patterns among preschool offspring of parents with and without psychopathology: Association with the development of psychopathology in childhood

BACKGROUND

Disturbed sleep during early childhood predicts social-emotional problems. However, it is not known how various early childhood sleep phenotypes are associated with the development of childhood psychopathology, nor whether these relationships vary as a function of parental psychopathology. We identified sleep phenotypes among preschool youth; examined whether these phenotypes were associated with child and parent factors; and determined if early sleep phenotypes predicted later childhood psychopathology.

METHODS

Using data from the Pittsburgh Bipolar Offspring study, parents with bipolar disorder (BD), non-BD psychopathology, and healthy controls reported about themselves and their offspring (n = 218) when their children were ages 2-5. Offspring and parents were interviewed directly approximately every 2 years from ages 6-18. Latent class analysis (LCA) identified latent sleep classes; we compared these classes on offspring demographics, parental sleep variables, and parental diagnoses. Kaplan-Meier survival models estimated hazard of developing any new-onset Axis-I disorders, as well as BD specifically, for each class.

RESULTS

The optimal LCA solution featured four sleep classes, which we characterized as (1) good sleep, (2) wake after sleep onset problems, (3) bedtime problems (e.g., trouble falling asleep, resists going to bed), and (4) poor sleep generally. Good sleepers tended to have significantly less parental psychopathology than the other three classes. Risk of developing new-onset Axis-I disorders was highest among the poor sleep class and lowest among the good sleep class.

CONCLUSIONS

Preschool sleep phenotypes are an important predictor of the development of psychopathology. Future work is needed to understand the biopsychosocial processes underlying these trajectories.

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.

Dialectical Behavior Therapy for Adolescents With Bipolar Disorder: A Randomized Clinical Trial

Importance

Early-onset bipolar disorder conveys substantial risk for suicide. No psychosocial intervention for this population expressly targets suicidal behavior.

Objective

To determine whether dialectical behavior therapy (DBT) for adolescents with bipolar spectrum disorder is more effective than standard of care (SOC) psychotherapy in decreasing suicide attempts over 1 year.

Design, Settings, and Participants

Adolescents aged 12 to 18 years diagnosed with bipolar spectrum disorder were recruited from a specialty outpatient psychiatric clinic between November 2014 and September 2019. Independent evaluators conducted quarterly assessments over 1 year with participants and parents. Data were analyzed from March 2021 to November 2022.

Interventions

Participants were randomly assigned to 1 year of DBT (36 sessions; n = 47) or SOC psychotherapy (schedule clinically determined; n = 53). All youth received medication management via a flexible algorithm.

Main Outcomes and Measures

Primary outcomes included suicide attempts over 1 year and mood symptoms and states (depression and hypomania/mania). Secondary analyses included moderation of DBT effects by history of suicide attempt and mediation through emotion dysregulation.

Results

Of 100 included participants, 85 (85%) were female, and the mean (SD) age was 16.1 (1.6) years. Participants were followed up over a mean (SD) of 47 (14) weeks. Both treatment groups demonstrated significant and similar improvement in mood symptoms and episodes over 1 year (standardized depression rating scale slope, -0.17; 95% CI, -0.31 to -0.03; standardized mania rating scale slope, -0.24; 95% CI, -0.34 to -0.14). DBT and SOC participants reported similar suicide attempt rates at intake as measured on the Adolescent Longitudinal Follow-Up Evaluation (ALIFE; mean [SD] attempts, 2.0 [4.5] vs 1.8 [3.9], respectively; P = .80). DBT participants reported slightly more suicide attempts at intake as measured on the Columbia-Suicide Severity Rating Scale Pediatric Version (C-SSRS; mean [SD] attempts, 1.4 [3.6] vs 0.6 [0.9]; P = .02). DBT participants reported significantly fewer suicide attempts over follow-up compared with SOC participants via the ALIFE (mean [SD] attempts per follow-up period, 0.2 [0.4] vs 1.1 [4.3], controlling for baseline attempts: P = .03) and the C-SSRS (mean [SD] attempts per follow-up period, 0.04 [0.2] vs 0.10 [0.3], controlling for baseline attempts; P = .03). DBT was significantly more effective than SOC psychotherapy at decreasing suicide attempts over 1 year (ALIFE: incidence rate ratio [IRR], 0.32; 95% CI, 0.11-0.96; C-SSRS: IRR, 0.13; 95% CI, 0.02-0.78). Decreased rate of suicide attempts in DBT was moderated by presence of lifetime history of suicide attempt and time (IRR, 0.23; 95% CI, 0.13-0.44) and mediated by improvement in emotion dysregulation (IRR, 0.61; 95% CI, 0.42-0.89), particularly for those with high baseline emotion dysregulation (standardized β, -0.59; 95% CI, -0.92 to -0.26).

Conclusions and Relevance

In this randomized clinical trial, DBT demonstrated efficacy in decreasing suicide attempts among the high-risk population of adolescents with bipolar spectrum disorder.

Early indicators of bipolar risk in preschool offspring of parents with bipolar disorder

BACKGROUND

Offspring of parents with bipolar disorder (BD-I/II) are at increased risk to develop the disorder. Previous work indicates that bipolar spectrum disorder (BPSD) is often preceded by mood/anxiety symptoms. In school-age offspring of parents with BD, we previously built a risk calculator to predict BPSD onset, which generates person-level risk scores. Here, we test whether preschool symptoms predict school-age BPSD risk.

METHODS

We assessed 113 offspring of parents with BD 1-3 times during preschool years (2-5 years old) and then approximately every 2 years for a mean of 10.6 years. We used penalized (lasso) regression with linear mixed models to assess relationships between preschool mood, anxiety, and behavioral symptoms (parent-reported) and school-age predictors of BPSD onset (i.e., risk score, subthreshold manic symptoms, and mood lability), adjusting for demographics and parental symptomatology. Finally, we conducted survival analyses to assess associations between preschool symptoms and school-age onset of BPSD and mood disorder.

RESULTS

Of 113 preschool offspring, 33 developed new-onset mood disorder, including 19 with new-onset BPSD. Preschool irritability, sleep problems, and parental factors were lasso-selected predictors of school-age risk scores. After accounting for demographic and parental factors, preschool symptoms were no longer significant. Lasso regressions to predict mood lability and subthreshold manic symptoms yielded similar predictors (irritability, sleep problems, and parental affective lability), but preschool symptoms remained predictive even after adjusting for parental factors (ps < .005). Exploratory analyses indicated that preschool irritability univariately predicted new-onset BPSD (p = .02) and mood disorder (p = .02).

CONCLUSIONS

These results provide initial prospective evidence that, as early as preschool, youth who will develop elevated risk scores, mood lability, and subthreshold manic symptoms are already showing symptomatology; these preschool symptoms also predict new-onset BPSD. While replication of findings in larger samples is warranted, results point to the need for earlier assessment of risk and development of early interventions.

Risk for Suicidal Behavior After Psychiatric Hospitalization Among Sexual and Gender Minority Patients

Importance

The months following inpatient psychiatric hospitalization are a period of high risk for suicidal behavior. Sexual and gender minority (SGM) individuals have elevated risk for suicidal behavior, but no prior research has examined whether SGM inpatients have disproportionate risk for suicidal behavior following discharge from psychiatric hospitalization.

Objectives

To evaluate whether SGM patients have elevated risk for suicidal behavior following discharge from psychiatric hospitalization compared with heterosexual and cisgender patients and to examine whether differences in risk across groups were accounted for by demographic characteristics and clinical factors known to be associated with suicidal behavior.

Design, Setting, and Participants

This prospective cohort study was conducted from August 2017 to July 2021 among inpatients aged 18 to 30 years who were voluntarily enrolled during psychiatric hospitalization. The study was conducted at an inpatient psychiatric hospital, with prospective data collected via follow-up visits and electronic health records.

Main Outcomes and Measures

Onset and/or recurrence of suicidal behavior following discharge from psychiatric hospitalization, assessed at follow-up visits and through electronic health records.

Results

A total of 160 patients were included, with 56 sexual minority (SM) and 15 gender minority (GM) patients. The median (IQR) age of the patients was 23.5 (20.4-27.6) years, 77 (48%) reported male sex assigned at birth, and 114 (71%) identified their race as White. During the follow-up period, 33 suicidal behavior events occurred (among 21% of patients). SM (hazard ratio [HR], 2.02; 95% CI, CI, 1.02-4.00; log-rank P = .04) and GM (HR, 4.27; 95% CI, 1.75-10.40; log-rank P < .001) patients had significantly higher risk for suicidal behavior compared with their heterosexual and cisgender counterparts, respectively, in bivariable analyses. Risk between SM and heterosexual patients was not different after controlling for demographic characteristics and clinical factors associated with suicidal behavior. GM patients exhibited elevated risk during the 100 days following discharge even after controlling for demographic and clinical characteristics (HR, 3.80; 95% CI, 1.18-11.19; P = .03).

Conclusions and Relevance

Within this cohort study of psychiatric patients, SGM patients had higher risk for suicidal behavior than non-SGM patients following discharge. While SM patients' risk was accounted for by clinical characteristics, GM patients' risk for suicidal behavior was not accounted for by their acute psychiatric state on admission. Future studies with larger subsamples of GM individuals are needed, and inpatient clinicians must attend to the unique needs of SGM individuals to ensure they receive affirming services.

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.

An intensive outpatient program for suicidal college students

Objective: College counseling centers (CCCs) have limited capacity to accommodate high-risk students who need more intensive care than traditional outpatient treatment. We describe an Intensive Outpatient Program (IOP) to meet the specialized needs of suicidal undergraduates. Participants: Suicidal undergraduates aged 18-24. Methods: Fact-gathering meetings with local universities confirmed high need for prompt access to IOP care for students presenting in crisis at CCCs and emergency rooms, and post-inpatient discharge. We thus iteratively designed and implemented the College Option Services for Teens at Risk (COSTAR) IOP. Results: The 6-week program includes initial diagnostic evaluation and risk assessment followed by weekly skills groups, individual therapy, and medication management. Between September 2017 and January 2020, 148 students (M age = 19.7) attended an average of 5.7 COSTAR group sessions (SD = 4.7). Conclusions: A specialty IOP for suicidal college students holds promise in a stepped care approach for at-risk college students.

Opioid use as a proximal risk factor for suicidal behavior in young adults

INTRODUCTION

There is a concomitant rise in suicide rates with the prevalence of opioids involved in overdose deaths, especially among adolescents and young adults. However, there are limited studies on whether opioid use prospectively predicts suicidal behavior in youth.

METHODS

Our sample included 183 psychiatric patients (18-30 years) admitted for a suicide attempt (SA), have current suicidal ideation (SI), and psychiatric controls without ideation or attempt (PC). Suicidal behavior was assessed using the Columbia Suicide Severity Rating Scale. We also recruited a healthy control group (HC; n = 40). Patients and controls were followed over a year. ANOVA, regression, and cox regression were used.

RESULTS

Suicide attempt (β = 0.87, CI [0.1-1.6], p = 0.02) and SI [(β = 0.75, CI [0.03-1.5], p = 0.04) were significantly more likely than HCs to have used opioids in the past year at baseline. Opioid use was associated with increased anxiety symptoms (β = 0.75, CI [0.001-1.5], p = 0.05), PTSD symptoms (β = 3.90, CI [1.1-6.7], p = 0.01), and aggression (β = 0.02, CI [0.01-0.04], p = 0.02). Opioid use in the month prior to hospitalization predicted SA at 6 months (OR = 1.87, CI [1.06-3.31], p = 0.032).

CONCLUSIONS

Opioid use is a proximal predictor for SA. These findings may help clinicians better identify patients at risk for suicidal behavior, allowing for more personalized treatment approaches.

Role of Polygenic Risk Score in the Familial Transmission of Bipolar Disorder in Youth

IMPORTANCE

Establishing genetic contributions to the transmission of bipolar disorder (BD) from parents to offspring may inform the risk of developing this disorder and further serve to validate BD in youth.

OBJECTIVE

To evaluate the specific association of BD polygenic risk scores (PRSs) on the familial transmission and validity of pediatric BD.

DESIGN, SETTING, AND PARTICIPANTS

This community-based case-control longitudinal study (Pittsburgh Biological Offspring Study) included parents with BD I/II and their offspring and parents without BD (healthy or non-BD psychopathology) and their offspring. Participants were recruited between March 2001 and May 2007, and analysis took place from December 2020 to September 2021.

EXPOSURES

PRSs for BD, major depressive disorder, schizophrenia, and attention-deficit/hyperactivity disorder.

MAIN OUTCOMES AND MEASURES

Participants were prospectively evaluated using standardized interviews blind to parental diagnosis. DNA was extracted from saliva and genotyped. PRSs were constructed based on independent large-scale genome-wide association studies.

RESULTS

A total of 156 parents with BD I/II and 180 parents without BD (mean [SD] age, 39.6 [7.9] years; 241 female [72%]) as well as 251 offspring of parents with BD and 158 offspring of parents without BD (mean [SD] age, 10.4 [4.7] years; 213 female [52%]) of European ancestry were analyzed. Participants were assessed a mean of 6.7 times during a mean (SD) of 13 (3.4) years of follow-up (84% retention). More offspring of parents with BD developed BD (58 [23.1%] vs 8 [5.1%]; P < .001) and depression (126 [50.2%] vs 52 [32.9%]; P < .001) compared with offspring of parents without BD. BD PRS was higher in both parents and offspring with BD than parents and offspring without BD (parents: odds ratio, 1.50; 95% CI, 1.19-1.89; P < .001; explained 4.8% of the phenotypic variance vs offspring: hazard ratio, 1.34; 95% CI, 1.03-1.7; P = .02; explained 5.0% of the phenotypic variance). BD PRS did not differ across BD subtypes. In a model combining parental and offspring BD PRS, the parental BD PRS association with offspring BD was fully mediated by offspring BD PRS (hazard ratio, 1.40; 95% CI, 1.05-1.86; P = .02). Parental BD had a stronger direct association than parental or offspring BD PRS with offspring BD risk (hazard ratio, 5.21; 95% CI, 1.86-14.62; P = .002), explaining 30% of the variance. Parental and offspring BD PRS explained 6% of the BD onset variance beyond parental diagnosis. There were no significant between-group differences in PRSs for major depressive disorder, schizophrenia, and attention-deficit/hyperactivity disorder in parents or offspring and they were not significantly associated with BD onset.

CONCLUSIONS AND RELEVANCE

The findings of this study add to the extant clinical validation of BD in youth. Parental BD and offspring BD PRS independently associated with the risk of BD in offspring. Although this is promising, the association of BD PRS was relatively small and cannot be used alone to determine BD risk until further developments occur.

Social media use and prospective suicidal thoughts and behaviors among adolescents at high risk for suicide

OBJECTIVE

To examine the relationship between social media use and suicidal thoughts and behaviors among adolescents in the first 30 days of an intensive outpatient program (IOP) for depression and suicidality.

METHOD

Participants included 100 adolescents who enrolled in an IOP for depression and suicidality and completed baseline measures of social media and weekly measures of depression and suicidal thoughts and behaviors at clinical visits over the next month.

RESULTS

Lower levels of social media use (overall and messaging) were associated with a greater likelihood of having suicidal ideation with plan over the next 30 days. There was no effect on suicidal behavior. Multilevel modeling indicated no main effects of social media use on depression or average days of suicidal thoughts. However, individuals with lower levels of social media use maintained more depression symptoms and days with passive death wish across the first month of treatment.

CONCLUSIONS

Among adolescents at high risk for suicide, less engagement in social media may reflect social anhedonia or withdrawal, which may heighten risk for more severe suicidal ideation or impede initial treatment. Findings highlight the importance of considering social media as an additional context when assessing social dysfunction in treatment for depression and suicidality.

A Longitudinal Study of Psychiatric Disorders in Offspring of Parents With Bipolar Disorder From Preschool to Adolescence

OBJECTIVE

To compare the prevalence of psychopathology, particularly bipolar disorder (BD), between preschool offspring of parents with BD and community controls.

METHOD

A total of 116 offspring of BD-I/II parents and 98 controls (53 parents with non-BD psychopathology and 45 healthy parents) were recruited at ages 2 to 5 years and followed on average 9.6 years (on average: 2-5: 1.6 times; after age 5: 4 times) (average ages at intake/last follow-up: 3.8/13.4, retention: 98%). Participants were evaluated with standardized instruments blinded to parental diagnoses.

RESULTS

After adjusting for confounders, offspring of BD parents only showed more attention-deficit/hyperactivity disorder (ADHD) during ages 2 to 5 years than the other 2 groups. After age 5, offspring of BD parents did not differ from offspring of parents with non-BD psychopathology, but they had more anxiety, ADHD, and behavior problems than offspring of healthy parents. Only offspring of BD parents developed BD-I/II: 3.4% (n = 4) and BD-not-otherwise-specified (BD-NOS): 11.2% (n = 13), with mean onset ages 11.4 and 7.4, respectively. About 70% of offspring with BD had non-BD disorders before BD. Only ADHD, diagnosed before age 6 years, and early-onset parental BD were significantly associated with BD risk.

CONCLUSION

Most offspring of BD parents did not develop BD, but they were at specific high risk for developing BD, particularly those with preschool ADHD and early-onset parental BD. BD symptoms were scarce during the preschool years and increased throughout the school age, mainly in the form of BD-NOS, a disorder that conveys poor prognosis and high risk to develop BD-I/II. Developing early interventions to delay or, ideally, to prevent its onset are warranted.

The p Factor Consistently Predicts Long-Term Psychiatric and Functional Outcomes in Anxiety-Disordered Youth

OBJECTIVE

Pediatric anxiety disorders can have a chronic course and are considered gateway disorders to adult psychopathology, but no consistent predictors of long-term outcome have been identified. A single latent symptom dimension that reflects features shared by all mental health disorders, the p factor, is thought to reflect mechanisms that cut across mental disorders. Whether p predicts outcome in youth with psychiatric disorders has not been examined. We tested whether the p factor predicted long-term psychiatric and functional outcomes in a large, naturalistically followed-up cohort of anxiety-disordered youth.

METHOD

Children and adolescents enrolled in a randomized controlled treatment trial of pediatric anxiety were followed-up on average 6 years posttreatment and then annually for 4 years. Structural equation modeling was used to estimate p at baseline. Both p and previously established predictors were modeled as predictors of long-term outcome.

RESULTS

Higher levels of p at baseline were related to more mental health disorders, poorer functioning, and greater impairment across all measures at all follow-up time points. p Predicted outcome above and beyond previously identified predictors, including diagnostic comorbidity at baseline. Post hoc analyses showed that p predicted long-term anxiety outcome, but not acute treatment outcome, suggesting that p may be uniquely associated with long-term outcome.

CONCLUSION

Children and adolescents with anxiety disorders who present with a liability toward broad mental health problems may be at a higher risk for poor long-term outcome across mental health and functional domains. Efforts to assess and to address this broad liability may enhance long-term outcome.

Long-term Service Use Among Youths Previously Treated for Anxiety Disorder

OBJECTIVE

(1) To describe rates of long-term service use among subjects previously enrolled in a landmark study of youth anxiety disorder treatment and followed into early adulthood; (2) to examine predictors of long-term service use; and (3) to examine the relationship between anxiety diagnosis and service use over time.

METHOD

The Child/Adolescent Anxiety Multimodal Extended Long-term Study prospectively assessed youths treated through the Child/Adolescent Anxiety Multimodal Study at ages 7-17 years into early adulthood. A total of 319 youths (mean age 17.7, 55.2% female) previously randomized to cognitive-behavioral therapy, sertraline, combination, or placebo for the treatment of anxiety participated; 318 had service use data. Four annual clinic assessments were conducted along with telephone check-ins every 6 months.

RESULTS

Overall, 65.1% of participants endorsed receiving some form of anxiety treatment over the course of the follow-up period, with more subjects reporting medication use than psychotherapy; 35.2% reported consistent use of services over the course of the study. Overall, service use declined over time in subjects with less severe anxiety but remained more steady in those with recurrent/chronic symptoms. Levels of life stress and depressive symptoms were associated with amount of service use over time whereas treatment-related variables (type of initial intervention, acute response, remission) were not. A subset of youths remained chronically anxious despite consistent service use.

CONCLUSION

These findings point to the need to develop models of care that approach anxiety disorders as chronic health conditions in need of active long-term management.

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).

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.

An Emulation of Randomized Trials of Administrating Antipsychotics in PTSD Patients for Outcomes of Suicide-Related Events

Post-traumatic stress disorder (PTSD) is a prevalent mental disorder marked by psychological and behavioral changes. Currently, there is no consensus of preferred antipsychotics to be used for the treatment of PTSD. We aim to discover whether certain antipsychotics have decreased suicide risk in the PTSD population, as these patients may be at higher risk. A total of 38,807 patients were identified with a diagnosis of PTSD through the ICD9 or ICD10 codes from January 2004 to October 2019. An emulation of randomized clinical trials was conducted to compare the outcomes of suicide-related events (SREs) among PTSD patients who ever used one of eight individual antipsychotics after the diagnosis of PTSD. Exclusion criteria included patients with a history of SREs and a previous history of antipsychotic use within one year before enrollment. Eligible individuals were assigned to a treatment group according to the antipsychotic initiated and followed until stopping current treatment, switching to another same class of drugs, death, or loss to follow up. The primary outcome was to identify the frequency of SREs associated with each antipsychotic. SREs were defined as ideation, attempts, and death by suicide. Pooled logistic regression methods with the Firth option were conducted to compare two drugs for their outcomes using SAS version 9.4 (SAS Institute, Cary, NC, USA). The results were adjusted for baseline characteristics and post-baseline, time-varying confounders. A total of 5294 patients were eligible for enrollment with an average follow up of 7.86 months. A total of 157 SREs were recorded throughout this study. Lurasidone showed a statistically significant decrease in SREs when compared head to head to almost all the other antipsychotics: aripiprazole, haloperidol, olanzapine, quetiapine, risperidone, and ziprasidone (p < 0.0001 and false discovery rate-adjusted p value < 0.0004). In addition, olanzapine was associated with higher SREs than quetiapine and risperidone, and ziprasidone was associated with higher SREs than risperidone. The results of this study suggest that certain antipsychotics may put individuals within the PTSD population at an increased risk of SREs, and that careful consideration may need to be taken when prescribed.

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.

Effects of Collaborative Care for Comorbid Attention Deficit Hyperactivity Disorder Among Children With Behavior Problems in Pediatric Primary Care

This study evaluates the impact of a 6-month care management intervention for 206 children diagnosed with comorbid attention deficit hyperactivity disorder (ADHD) from a sample of 321 five- to 12-year-old children recruited for treatment of behavior problems in 8 pediatric primary care offices. Practices were cluster-randomized to Doctor Office Collaboration Care (DOCC) or Enhanced Usual Care (EUC). Chart reviews documented higher rates of service delivery, prescription of medication for ADHD, and titration in DOCC (vs EUC). Based on complex conditional models, DOCC showed greater acute improvement in individualized ADHD treatment goals and follow-up improvements in quality of life and ADHD and oppositional defiant disorder goals. Medication use had a significant effect on acute and follow-up ADHD symptom reduction and quality of life. Medication continuity was associated with some long-term gains. A collaborative care intervention for behavior problems that incorporated treatment guidelines for ADHD in primary care was more effective than psychoeducation and facilitated referral to community treatment.

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.

A Longitudinal Study of Family Functioning in Offspring of Parents Diagnosed With Bipolar Disorder

OBJECTIVE

To compare the longitudinal course of family functioning in offspring of parents with bipolar disorder (BD), offspring of parents with non-BD psychopathology, and offspring of healthy control (HC) parents.

METHOD

Offspring of parents with BD (256 parents and 481 offspring), parents without BD (82 parents and 162 offspring), and HC parents (88 parents and 175 offspring) 7 to 18 years of age at intake, from the Bipolar Offspring Study (BIOS), were followed for an average of 4.3 years. Family functioning was evaluated using the child- and parent-reported Family Adaptability and Cohesion Scale-II and the Conflict Behavior Questionnaire. The data were analyzed using multivariate multilevel regression, generalized linear estimating equation models, and path analysis.

RESULTS

Families of parents with BD and parents with non-BD psychopathology showed lower cohesion and adaptability and higher conflict compared with HC families. There were no significant differences in cohesion and adaptability between families of parents with psychopathology. The effect of parental psychopathology on family functioning was mediated by parental psychosocial functioning and, to a lesser extent, offspring disorders. In all 3 groups, parent-reported family conflict was significantly higher than child-reported conflict. Across groups, family cohesion decreased over follow-up, whereas conflict increased.

CONCLUSION

Any parental psychopathology predicted family impairment. These results were influenced by the offspring's age and were mediated by parental psychosocial functioning and, to a lesser degree, by offspring psychopathology. These findings emphasize the need to routinely assess family functioning in addition to psychopathology and provide appropriate interventions to parents and offspring.

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.

White matter - emotion processing activity relationships in youth offspring of bipolar parents

BACKGROUND

Early detection of Bipolar Disorder (BD) is critical for targeting interventions to delay or prevent illness onset. Yet, the absence of objective BD biomarkers makes accurately identifying at-risk youth difficult. In this study, we examined how relationships between white matter tract (WMT) structure and activity in emotion processing neural circuitry differentiate youth at risk for BD from youth at risk for other psychiatric disorders.

METHODS

Offspring (ages 8-17) of parents with BD (OBP, n = 32), offspring of comparison parents with non-BD psychopathology (OCP, n = 30), and offspring of healthy parents (OHP, n = 24) underwent diffusion tensor and functional magnetic resonance imaging while performing an emotional face processing task. Penalized and multiple regression analyses included GROUP(OBP,OCP)xWMT interactions as main independent variables, and emotion processing activity as dependent variables, to determine significant group differences in WMT-activity relationships.

RESULTS

8 GROUPxWMT interaction variables contributed to 16.5% of the variance in amygdala and prefrontal cortical activity to happy faces. Of these, significant group differences in slopes (inverse for OBP, positive for OCP) existed for the relationship between forceps minor radial diffusivity and rostral anterior cingulate activity (p = 0.014). Slopes remained significantly different in unmedicated youth without psychiatric disorders (p = 0.017) and were moderated by affective lability symptoms (F(1,29) = 5.566, p = 0.036).

LIMITATIONS

Relatively small sample sizes were included.

CONCLUSIONS

Forceps minor radial diffusivity-rostral anterior cingulate activity relationships may reflect underlying neuropathological processes that contribute to affectively labile youth at risk for BD and may help differentiate them from youth at risk for other psychiatric disorders.

Pharmacotherapy Adherence for Pediatric Anxiety Disorders: Predictors and Relation to Child Outcomes

Background

Pharmacotherapy is considered an evidenced-based treatment for anxious youth. There is a need to better understand the relation between medication adherence and child outcomes.

Objective

This study prospectively examined:1) baseline predictors of adherence and 2) the relation between medication adherence and clinical outcomes in children and adolescents with anxiety disorders.

Methods

Participants were 349 youth randomized to sertraline, pill placebo, or sertraline plus cognitive behavioral therapy in the Child/Adolescent Anxiety Multimodal Study (CAMS) and followed over 12 weeks. The measure of pharmacotherapy adherence used was pharmacotherapist (PT) ratings of adherence at each session. Four domains of baseline predictors were examined (demographics, child clinical variables, family/parent variables, and treatment variables).

Results

Multiple regression analyses revealed few significant predictors of adherence. The most robust predictors of greater adherence were living with two parents and parents' positive expectations that medication would lead to better outcomes. Pharmacotherapists' ratings of higher adherence predicted higher global functioning at post treatment and treatment responder status.

Conclusions

In order to increase adherence, improving expectations and instilling hope for positive outcomes and problem solving ways to overcome pragmatic barriers associated with single parent families is recommended.

Association of Neuroimaging Measures of Emotion Processing and Regulation Neural Circuitries With Symptoms of Bipolar Disorder in Offspring at Risk for Bipolar Disorder

IMPORTANCE

Bipolar disorder (BD) is difficult to distinguish from other psychiatric disorders. Neuroimaging studies can identify objective markers of BD risk.

OBJECTIVE

To identify neuroimaging measures in emotion processing and regulation neural circuitries and their associations with symptoms specific to youth at risk for BD.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional (August 1, 2011, to July 31, 2017) and longitudinal (February 1, 2013, to November 30, 2017) neuroimaging study performed at the University of Pittsburgh Medical Center compared a sample of 31 offspring of parents with BD (OBP) with 28 offspring of comparison parents with non-BD psychopathologies (OCP) and 21 offspring of healthy parents (OHP); OBP, OCP, and OHP were recruited from the Bipolar Offspring Study and the Longitudinal Assessment of Manic Symptoms Study.

MAIN OUTCOMES AND MEASURES

Group differences in activity and functional connectivity during emotional face processing and n-back task performance in amygdala, dorsolateral and ventrolateral prefrontal cortices (PFC), caudal anterior cingulate cortices (cACC), and rostral anterior cingulate cortices (rACC) neuroimaging measures showing between-group differences and symptom severity (anxiety, affective lability, depression, mania). We hypothesized that elevated amygdala activity and/or lower PFC activity and abnormal amygdala to PFC functional connectivity would distinguish OBP from OCP and OHP, and magnitudes of these abnormalities would positively correlate with elevated symptom severity. We explored associations between changes in neuroimaging and symptom measures over follow-up (mean [SD], 2.9 [1.4] years) in a subset of participants (n = 30).

RESULTS

Eighty participants were included (mean [SD] age, 14.2 (2.1) years; 35 female). Twelve neuroimaging measures explained 51% of the variance in the results of neuroimaging measures overall. Of the 12, 9 showed significant main associations of the group; however, after post hoc analyses and Bonferroni corrections, only 7 showed statistically significant associations between groups (corrected P < .05 for all). Of the 7, 2 showed significant relationships with symptoms. Offspring of parents with BD had greater right rACC activity when regulating attention to happy faces vs OCP (mean [SD] difference, 0.744 [0.249]; 95% CI, 0.134-1.354; P = .01), which positively correlated with affective lability severity (ρ = 0.304; uncorrected P = .006). Offspring of parents with BD had greater amygdala to left cACC functional connectivity when regulating attention to fearful faces vs OCP (mean [SD] difference, 0.493 [0.169]; 95% CI, 0.079-0.908; P = .01). Increases in this measure positively correlated with increases in affective lability over follow-up (r = 0.541; P = .003).

CONCLUSIONS AND RELEVANCE

Greater anterior cingulate cortex activity and functional connectivity during emotion regulation tasks may be specific markers of BD risk. These findings highlight potential neural targets to aid earlier identification of and guide new treatment developments for BD.

Results from the Child/Adolescent Anxiety Multimodal Longitudinal Study (CAMELS): Functional outcomes

OBJECTIVE

To report functional outcomes from the multisite Child/Adolescent Anxiety Multimodal Extended Long-term Study (CAMELS), which examined the impact of youth anxiety treatment (cognitive-behavioral therapy [CBT], coping cat; Sertraline, SRT; COMB [CBT + SRT]; pill placebo) on (a) global and (b) domain-specific functioning assessed an average of 3.1 times, 3- to 12-years postrandomization (first assessment = mean 6.5 years postrandomization).

METHOD

Three-hundred and 19 of 488 families from the Child/Adolescent Anxiety Multimodal Study (CAMS; Walkup et al., 2008) participated. Growth curve modeling examined the impact of treatment condition and acute treatment outcomes (i.e., response, remission) on global functioning, global and domain-specific impairment, and life satisfaction across follow-up visits. Logistic regressions explored the impact of treatment remission and condition on low frequency events (arrests/convictions) and education.

RESULTS

Treatment responders and remitters demonstrated better global functioning, decreased overall impairment, and increased life satisfaction at follow-up. Treatment remission, but not response, predicted decreased domain-specific impairment (social relationships, self-care/independence, academic functioning), and maintenance of increased life satisfaction across follow-ups. Participants in the CBT condition, compared with pill placebo, demonstrated improved trajectories pertaining to life satisfaction, overall impairment, and impairment in academic functioning. Randomization to CBT or COMB treatment was associated with increasing employment rates. Trajectories for participants randomized to SRT was not significantly different from placebo. Treatment outcome and condition did not predict legal outcomes, school/work variables, or family life.

CONCLUSION

Positive early intervention outcomes are associated with improved overall functioning, life satisfaction, and functioning within specific domains 6.5 years posttreatment. Treatment type differentially predicted trajectories of functioning. Findings support the positive impact of pediatric anxiety treatment into adolescence and early adulthood.

Results From the Child/Adolescent Anxiety Multimodal Extended Long-Term Study (CAMELS): Primary Anxiety Outcomes

OBJECTIVE

To report anxiety outcomes from the multisite Child/Adolescent Anxiety Multimodal Extended Long-term Study (CAMELS). Rates of stable anxiety remission (defined rigorously as the absence of all DSM-IV TR anxiety disorders across all follow-up years) and predictors of anxiety remission across a 4-year period, beginning 4 to 12 years after randomization to 12 weeks of medication, cognitive-behavioral therapy (CBT), their combination, or pill placebo were examined. Examined predictors of remission included acute treatment response, treatment assignment, baseline child and family variables, and interim negative life events.

METHOD

Data were from 319 youths (age range 10.9-25.2 years; mean age 17.12 years) originally diagnosed with separation, social, and/or generalized anxiety disorders and enrolled in the multi-site Child/Adolescent Anxiety Multimodal Study (CAMS). Participants were assessed annually by independent evaluators using the age-appropriate version of the Anxiety Disorders Interview Schedule and completed questionnaires (eg, about family functioning, life events, and mental health service use).

RESULTS

Almost 22% of youth were in stable remission, 30% were chronically ill, and 48% were relapsers. Acute treatment responders were less likely to be in the chronically ill group (odds ratio = 2.73; confidence interval = 1.14-6.54; p < .02); treatment type was not associated with remission status across the follow-up. Several variables (eg, male gender) predicted stable remission from anxiety disorders.

CONCLUSION

Findings suggest that acute positive response to anxiety treatment may reduce risk for chronic anxiety disability; identified predictors can help tailor treatments to youth at greatest risk for chronic illness.

Mediators of Treatment Outcomes for Anxious Children and Adolescents: The Role of Somatic Symptoms

Cognitive behavioral therapy (CBT) and selective serotonin reuptake inhibitors are effective treatments for pediatric anxiety disorders. However, the mechanisms of these treatments are unknown. Previous research indicated that somatic symptoms are reduced following treatment, but it is unclear if their reductions are merely a consequence of treatment gains. This study examined reductions in somatic symptoms as a potential mediator of the relationship between treatment and anxiety outcomes. Participants were 488 anxious youth ages 7-17 (M = 10.7), 50.4% male, 78.9% Caucasian, enrolled in Child/Adolescent Anxiety Multimodal Study, a large randomized control trial comparing 12-week treatments of CBT, sertraline, a combination of CBT and sertraline, and a pill placebo. Causal mediation models were tested in R using data from baseline, 8-, and 12-week evaluations. Somatic symptoms were assessed using the Panic/Somatic subscale from the Screen for Child Anxiety Related Emotional Disorders. Youth outcomes were assessed using the Pediatric Anxiety Rating Scale and Children's Global Assessment Scale. Reductions in somatic symptoms mediated improvement in anxiety symptoms and global functioning for those in the sertraline-only condition based on parent report. Conditions involving CBT and data based on child reported somatic symptoms did not show a mediation effect. Findings indicate that reductions in somatic symptoms may be a mediator of improvements for treatments including pharmacotherapy and not CBT. Although the overall efficacy of sertraline and CBT for anxiety may be similar, the treatments appear to function via different mechanisms.

Placebo Response in Pediatric Anxiety Disorders: Results from the Child/Adolescent Anxiety Multimodal Study

OBJECTIVES

The aim of this study is to identify predictors of pill placebo response and to characterize the temporal course of pill placebo response in anxious youth.

METHODS

Data from placebo-treated patients (N = 76) in the Child/Adolescent Anxiety Multimodal Study (CAMS), a multisite, randomized controlled trial that examined the efficacy of cognitive-behavioral therapy, sertraline, their combination, and placebo for the treatment of separation, generalized, and social anxiety disorders, were evaluated. Multiple linear regression models identified features associated with placebo response and models were confirmed with leave-one-out cross-validation. The likelihood of improvement in patients receiving pill placebo-over time-relative to improvement associated with active treatment was determined using probabilistic Bayesian analyses.

RESULTS

Based on a categorical definition of response (Clinical Global Impressions-Improvement Scale score ≤2), nonresponders (n = 48), and pill placebo responders (n = 18) did not differ in age (p = 0.217), sex (p = 0.980), race (p = 0.743), or primary diagnosis (all ps > 0.659). In terms of change in anxiety symptoms, separation anxiety disorder and treatment expectation were associated with the degree of pill placebo response. Greater probability of placebo-related anxiety symptom improvement was observed early in the course of treatment (baseline to week 4, p < 0.0001). No significant change in the probability of placebo-related improvement was observed after week 4 (weeks 4-8, p = 0.07; weeks 8-12, p = 0.85), whereas the probability of improvement, in general, significantly increased week over week with active treatment.

CONCLUSIONS

Pill placebo-related improvement occurs early in the course of treatment and both clinical factors and expectation predict this improvement. Additionally, probabilistic approaches may refine our understanding and prediction of pill placebo response.

Assessment of a Person-Level Risk Calculator to Predict New-Onset Bipolar Spectrum Disorder in Youth at Familial Risk

IMPORTANCE

Early identification of individuals at high risk for the onset of bipolar spectrum disorder (BPSD) is key from both a clinical and research perspective. While previous work has identified the presence of a bipolar prodrome, the predictive implications for the individual have not been assessed, to date.

OBJECTIVE

To build a risk calculator to predict the 5-year onset of BPSD in youth at familial risk for BPSD.

DESIGN, SETTING, AND PARTICIPANTS

The Pittsburgh Bipolar Offspring Study is an ongoing community-based longitudinal cohort investigation of offspring of parents with bipolar I or II (and community controls), recruited between November 2001 and July 2007, with a median follow-up period of more than 9 years. Recruitment has ended, but follow-up is ongoing. The present analysis included offspring of parents with bipolar I or II (aged 6-17 years) who had not yet developed BPSD at baseline.

MAIN OUTCOMES AND MEASURES

This study tested the degree to which a time-to-event model, including measures of mood and anxiety, general psychosocial functioning, age at mood disorder onset in the bipolar parent, and age at each visit, predicted new-onset BPSD. To fully use longitudinal data, the study assessed each visit separately, clustering within individuals. Discrimination was measured using the time-dependent area under the curve (AUC), predicting 5-year risk; internal validation was performed using 1000 bootstrapped resamples. Calibration was assessed by comparing observed vs predicted probability of new-onset BPSD.

RESULTS

There were 412 at-risk offspring (202 [49.0%] female), with a mean (SD) visit age of 12.0 (3.5) years and a mean (SD) age at new-onset BPSD of 14.2 (4.5) years. Among them, 54 (13.1%) developed BPSD during follow-up (18 with BD I or II); these participants contributed a total of 1058 visits, 67 (6.3%) of which preceded new-onset BPSD within the next 5 years. Using internal validation to account for overfitting, the model provided good discrimination between converting vs nonconverting visits (AUC, 0.76; bootstrapped 95% CI, 0.71-0.82). Important univariate predictors of outcome (AUC range, 0.66-0.70) were dimensional measures of mania, depression, anxiety, and mood lability; psychosocial functioning; and parental age at mood disorder.

CONCLUSIONS AND RELEVANCE

This risk calculator provides a practical tool for assessing the probability that a youth at familial risk for BPSD will develop new-onset BPSD within the next 5 years. Such a tool may be used by clinicians to inform frequency of monitoring and treatment options and for research studies to better identify potential participants at ultra high risk of conversion.

Characteristics of depression among offspring at high and low familial risk of bipolar disorder

OBJECTIVES

Having a parent with bipolar disorder (BP) is a very strong risk factor for developing BP. Similarly, depression among youth is a clinical risk factor for subsequent BP. We evaluated whether mood symptomatology in depressed youth is different between those at high and low familial risk to develop BP.

METHODS

The most severe major depressive episode in BP offspring (N=61) and community control offspring (N=20) was evaluated using expanded depression and mania rating scales derived from the Schedule for Affective Disorders and Schizophrenia for Children Present Version. The results were adjusted for any between-group significant demographic differences and for multiple comparisons.

RESULTS

The severity of depressive symptoms and the percentage of offspring with severe depressive symptoms, especially atypical depressive features, were significantly higher in the depressed offspring of BP parents compared to the depressed controls (P_s <.05). The depressive symptoms were helpful to identify a high-risk group (e.g., odds ratio [OR] for hypersomnia: 22.4, 95% confidence interval [CI]: 1.3-404, P=.04). In addition, there were significantly more depressed offspring of BP parents with subsyndromal manic symptoms than controls (52.5% vs 20%, OR: 4.2, 95% CI: 1.2-14.7, P<.01).

CONCLUSIONS

Depressed BP offspring had more severe depression including atypical depressive symptoms, and were more likely to have subsyndromal mixed manic symptoms than depressed control offspring. Prospective studies to evaluate whether these youth are at high risk to develop BP are warranted. If replicated, the results of this study have important clinical (e.g., treatment of depression in depressed offspring of BP parents) and research implications.

Psychometrics of the screen for adult anxiety related disorders (SCAARED)- A new scale for the assessment of DSM-5 anxiety disorders

OBJECTIVE

To examine the psychometrics of the Screen for Adult Anxiety Related Disorders (SCAARED).

METHODS

The SCAARED was adapted from the Screen for Child Anxiety Related Emotional Disorders. Participants (N=336) ages 18-27 years old were evaluated using the Structured Clinical Interview for DSM-IV Disorders (SCID). The SCAARED was completed at or within two-weeks before the SCID. The psychometrics of the SCAARED were analyzed using standard statistical analyses including principal components, and Receiver Operant Curve analyses. A replication was performed in an age/sex matched independent sample (N=158).

RESULTS

The SCAARED showed four factors: somatic/panic/agoraphobia, generalized anxiety, separation anxiety, and social anxiety. The total and each factor scores demonstrated good internal consistency (α=0.86-0.97) and good discriminant validity between anxiety and other disorders and within anxiety disorders for generalized and social anxiety. Area Under the Curve for the total and each of the factor scores ranged between 0.72 and 0.84 (p<0.0001). These results were replicated in the independent sample.

CONCLUSIONS

The SCAARED showed excellent psychometric properties supporting its use to screen adults for anxiety disorders, longitudinal studies following youth into adulthood and studies comparing child and adult populations. Further replication studies in larger community and clinical samples are indicated.

Longitudinal sleep phenotypes among offspring of bipolar parents and community controls

BACKGROUND

Sleep disturbances are a prominent feature of bipolar disorder (BP). However, it remains unclear how sleep phenotypes may evolve among at-risk youth, and their relevance to BP onset.

METHODS

Pittsburgh Bipolar Offspring Study (BIOS) offspring (ages 10-18) and their parents completed assessments approximately every two years pertaining to current psychopathology and offspring sleep habits. A latent transition analysis (LTA) identified latent sleep groups within offspring based on their ratings of six sleep domains using the School Sleep Habits Survey. Demographic and clinical characteristics were compared between sleep groups. Logistic regression tested links between sleep group and BP onset at the subsequent assessment.

RESULTS

The LTA model identified latent groups of good, poor, and variable sleepers. We observed an overall trend of good sleep becoming variable, and then poor, as youth age. Offspring in the poor sleep group were more likely to have psychopathology. Adjusting for age and depression, poor sleepers had nearly twice the odds of developing BP relative to good (OR=1.99, CI=0.45-8.91) or variable (OR=2.03, CI=0.72-5.72) sleepers.

LIMITATIONS

Limitations include the use of proximal sleep phenotypes to predict BP onset, and a self-report measure of sleep CONCLUSIONS: We found three non-overlapping sleep phenotype groups in a large sample of offspring of bipolar probands and offspring of demographically-matched community control parents. Clinicians should consider that youth will likely experience variable and/or poor sleep as they age, and that at-risk youth with poor sleep may be at increased risk of developing MDD and BP at their next assessment.

Child and Adolescent Adherence With Cognitive Behavioral Therapy for Anxiety: Predictors and Associations With Outcomes

Cognitive behavioral therapy (CBT) for anxiety disorders is effective, but nonadherence with treatment may reduce the benefits of CBT. This study examined (a) four baseline domains (i.e., demographic, youth clinical characteristics, therapy related, family/parent factors) as predictors of youth adherence with treatment and (b) the associations between youth adherence and treatment outcomes. Data were from 279 youth (7-17 years of age, 51.6% female; 79.6% White, 9% African American), with Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.) diagnoses of separation anxiety disorder, generalized anxiety disorder, and/or social phobia, who participated in CBT in the Child/Adolescent Anxiety Multimodal Study. Adherence was defined in three ways (session attendance, therapist-rated compliance, and homework completion). Multiple regressions revealed several significant predictors of youth adherence with CBT, but predictors varied according to the definition of adherence. The most robust predictors of greater adherence were living with both parents and fewer youth comorbid externalizing disorders. With respect to outcomes, therapist ratings of higher youth compliance with CBT predicted several indices of favorable outcome: lower anxiety severity, higher global functioning, and treatment responder status after 12 weeks of CBT. Number of sessions attended and homework completion did not predict treatment outcomes. Findings provide information about risks for youth nonadherence, which can inform treatment and highlight the importance of youth compliance with participating in therapy activities, rather than just attending sessions or completing homework assignments.

Toward the Definition of a Bipolar Prodrome: Dimensional Predictors of Bipolar Spectrum Disorders in At-Risk Youths

OBJECTIVE

The authors sought to assess dimensional symptomatic predictors of new-onset bipolar spectrum disorders in youths at familial risk of bipolar disorder ("at-risk" youths).

METHOD

Offspring 6-18 years old of parents with bipolar I or II disorder (N=359) and community comparison offspring (N=220) were recruited. At baseline, 8.4% of the offspring of bipolar parents had a bipolar spectrum disorder. Over 8 years, 14.7% of offspring for whom follow-up data were available (44/299) developed a new-onset bipolar spectrum disorder (15 with bipolar I or II disorder). Measures collected at baseline and follow-up were reduced using factor analyses, and factors (both at baseline and at the visit prior to conversion or last contact) were assessed as predictors of new-onset bipolar spectrum disorders.

RESULTS

Relative to comparison offspring, at-risk and bipolar offspring had higher baseline levels of anxiety/depression, inattention/disinhibition, externalizing, subsyndromal manic, and affective lability symptoms. The strongest predictors of new-onset bipolar spectrum disorders were baseline anxiety/depression, baseline and proximal affective lability, and proximal subsyndromal manic symptoms (p<0.05). While affective lability and anxiety/depression were elevated throughout follow-up in those who later developed a bipolar spectrum disorder, manic symptoms increased up to the point of conversion. A path analysis supported the hypothesis that affective lability at baseline predicts a new-onset bipolar spectrum disorder in part through increased manic symptoms at the visit prior to conversion; earlier parental age at mood disorder onset was also significantly associated with an increased risk of conversion. While youths without anxiety/depression, affective lability, and mania (and with a parent with older age at mood disorder onset) had a 2% predicted chance of conversion to a bipolar spectrum disorder, those with all risk factors had a 49% predicted chance of conversion.

CONCLUSIONS

Dimensional measures of anxiety/depression, affective lability, and mania are important predictors of new-onset bipolar spectrum disorders in at-risk youths. These symptoms emerged from among numerous other candidates, underscoring the potential clinical and research utility of these findings.

Differences in sleep disturbances among offspring of parents with and without bipolar disorder: association with conversion to bipolar disorder

OBJECTIVES

Disruptions in sleep and dysregulation in circadian functioning may represent core abnormalities in the pathophysiology of bipolar disorder (BP). However, it is not clear whether these dysfunctions are state or trait markers of BP. This report compared sleep and circadian phenotypes among three groups: offspring of parents with BP diagnosed with BP at intake (BP/OB; n = 47), offspring of parents with BP without BP at intake (non-BP/OB; n = 386), and offspring of matched control parents who did not have BP (controls; n = 301). We also examined the association of baseline sleep parameters with subsequent development of BP among the non-BP/OB group.

METHODS

Pittsburgh Bipolar Offspring Study youth (ages 6-18 years) and their parents completed assessments every two years pertaining to the child's sleep and circadian phenotypes and current psychopathology. Mixed-effects models examined differences in baseline sleep and circadian variables among the three groups.

RESULTS

BP/OB offspring who were in a mood episode differed significantly on sleep parameters from the non-BP/OB and the offspring of controls, such as having inadequate sleep. Mixed logistic regression procedures showed that baseline sleep and circadian variables, such as frequent waking during the night, significantly predicted the development of BP among non-BP/OB over longitudinal follow-up.

CONCLUSIONS

While lifetime diagnostic status accounted for differences among the groups in sleep and circadian disturbances, psychopathology explained the differences even further. Additionally, sleep disturbance may be a prognostic indicator of the development of BP in high-risk youth. Future studies are required to further disentangle whether sleep and circadian disruption are state or trait features of BP.

Sleep-Related Problems and the Effects of Anxiety Treatment in Children and Adolescents

This study examined (a) demographic and clinical characteristics associated with sleep-related problems (SRPs) among youth with anxiety disorders, and (b) the impact of anxiety treatment: cognitive-behavioral therapy (CBT; Coping Cat), medication (sertraline), their combination, and pill placebo on SRPs. Youth (N = 488, ages 7-17, 50% female, 79% White) with a principal diagnosis of generalized anxiety disorder, separation anxiety disorder, or social phobia participated. SRPs were reported by parents and youth. Findings differed by informant and by type of SRP, with evidence that SRPs are associated with age, anxiety severity, externalizing problems, functional impairment, and family burden at pretreatment. Anxiety treatment reduced SRPs; effect sizes were small to medium. Reductions in parent-reported separation-related sleep difficulties were significantly greater in active treatment than in the placebo condition, with the greatest reductions reported by parents of youth whose active treatment was multimodal or included sertraline. Youth whose anxiety treatment involved CBT reported significantly greater decreases in dysregulated sleep (e.g., sleeplessness). Both CBT for anxiety and sertraline appear to be somewhat effective in reducing SRPs, and multimodal treatment may be preferable depending on the symptom presentation. To inform practice, future research should examine a broad range of SRPs, incorporate objective measures of sleep, and evaluate the impact of behavioral strategies that directly target SRPs in youth with anxiety disorders.

Diagnostic Precursors to Bipolar Disorder in Offspring of Parents With Bipolar Disorder: A Longitudinal Study

OBJECTIVE

The authors sought to identify diagnostic risk factors of manic, mixed, or hypomanic episodes in the offspring of parents with bipolar disorder ("high-risk offspring").

METHOD

High-risk offspring 6-18 years old (N=391) and demographically matched offspring (N=248) of community parents without bipolar disorder were assessed longitudinally with standardized diagnostic instruments by staff blind to parental diagnoses. Follow-up assessments were completed in 91% of the offspring (mean follow-up interval, 2.5 years; mean follow-up duration, 6.8 years).

RESULTS

Compared with community offspring, high-risk offspring had significantly higher rates of subthreshold mania or hypomania (13.3% compared with 1.2%), manic, mixed, or hypomanic episodes (9.2% compared with 0.8%), and major depressive episodes (32.0% compared with 14.9%). They also had higher rates of attention deficit hyperactivity disorder (30.7% compared with 18.1%), disruptive behavior disorders (27.4% compared with 15.3%), anxiety disorders (39.9% compared with 21.8%), and substance use disorders (19.9% compared with 10.1%), but not unipolar major depressive disorder (major depression with no bipolarity; 18.9% compared with 13.7%). Multivariate Cox regressions showed that in the high-risk offspring, subthreshold manic or hypomanic episodes (hazard ratio=2.29), major depressive episodes (hazard ratio=1.99), and disruptive behavior disorders (hazard ratio=2.12) were associated with subsequent manic, mixed, or hypomanic episodes. Only subthreshold manic or hypomanic episodes (hazard ratio=7.57) were associated when analyses were restricted to prospective data.

CONCLUSIONS

Subthreshold manic or hypomanic episodes were a diagnostic risk factor for the development of manic, mixed, or hypomanic episodes in the offspring of parents with bipolar disorder and should be a target for clinical assessment and treatment research. Major depressive episodes and disruptive behavior disorders are also indications for close clinical monitoring of emergent bipolarity in high-risk offspring.

The longitudinal course of sleep timing and circadian preferences in adults with bipolar disorder

OBJECTIVES

To study the longitudinal course of sleep timing and circadian preferences in individuals with bipolar disorder (BP) compared to individuals with non-BP psychopathology and healthy controls.

METHODS

Individuals with bipolar I and bipolar II disorder (n = 257), non-BP psychopathology (n = 105), and healthy controls (n = 55) (mean age 40.2 years, 21.3% male, 85.1% Caucasian) were followed on average every 27 months for a mean of four years. Sleep timing parameters and circadian preference were reported using the Sleep Timing Questionnaire and The Composite Scale for Morningness. Group comparisons were adjusted for multiple comparisons and between-group differences in demographic variables and psychopharmacological treatment.

RESULTS

Regardless of their current mood state, individuals with BP showed more sleep onset latency (SOL), wakening after sleep onset (WASO), and evening preference in comparison to both individuals with non-BP psychopathology and healthy controls. Individuals with BP also showed less stability of bed and awakening times in comparison to the other two groups, though these results were dependent on mood state. Non-BP individuals only showed more WASO and less stability in bed and awakening times before work/school days than healthy controls. Adjusting for comorbid disorders yielded similar results. Within-group analyses found little to no effect of time and BP subtype on sleep timing and circadian preference.

CONCLUSIONS

Disturbances of sleep timing are prominent in individuals with BP. These disturbances are worse during mood episodes, but still apparent during euthymic periods. Evening preference was not associated with polarity type, or mood state in BP, suggesting that this characteristic may be a trait marker.

Trajectories of change in youth anxiety during cognitive-behavior therapy

OBJECTIVE

To evaluate changes in the trajectory of youth anxiety following the introduction of specific cognitive-behavior therapy (CBT) components: relaxation training, cognitive restructuring, and exposure tasks.

METHOD

Four hundred eighty-eight youths ages 7-17 years (50% female; 74% ≤ 12 years) were randomly assigned to receive either CBT, sertraline (SRT), their combination (COMB), or pill placebo (PBO) as part of their participation in the Child/Adolescent Anxiety Multimodal Study (CAMS). Youths in the CBT conditions were evaluated weekly by therapists using the Clinical Global Impression Scale-Severity (CGI-S; Guy, 1976) and the Children's Global Assessment Scale (CGAS; Shaffer et al., 1983) and every 4 weeks by blind independent evaluators (IEs) using the Pediatric Anxiety Ratings Scale (PARS; RUPP Anxiety Study Group, 2002). Youths in SRT and PBO were included as controls.

RESULTS

Longitudinal discontinuity analyses indicated that the introduction of both cognitive restructuring (e.g., changing self-talk) and exposure tasks significantly accelerated the rate of progress on measures of symptom severity and global functioning moving forward in treatment; the introduction of relaxation training had limited impact. Counter to expectations, no strategy altered the rate of progress in the specific domain of anxiety that it was intended to target (i.e., somatic symptoms, anxious self-talk, avoidance behavior).

CONCLUSIONS

Findings support CBT theory and suggest that cognitive restructuring and exposure tasks each make substantial contributions to improvement in youth anxiety. Implications for future research are discussed. (PsycINFO Database Record

The effects of parental mood on reports of their children's psychopathology

OBJECTIVE

In this study, we aimed to assess whether current mood state (depressed or manic/hypomanic) among parents with a mood disorder would affect their reports of their offspring's psychopathology.

METHOD

Sixty-five parents with current depression, 42 parents with current mania/hypomania, 181 parents with mood disorder in remission, and their offspring (n = 479, aged 6-18 years) completed assessments of offspring psychopathology as part of the Pittsburgh Bipolar Offspring Study (BIOS). We compared rates of offspring psychopathology assessed using the following: a clinician-administered semi-structured interview with parent and child using the Schedule for Affective Disorders and Schizophrenia for School-Age Children (K-SADS); parent-reported Child Behavior Checklist (CBCL); offspring self-reported Youth Self Reports (YSR) for those 11 years and older (n = 250); and teachers' reports when available (n = 209).

RESULTS

There were no between-group differences in rates of psychopathology yielded from the K-SADS, except for more depressive disorders in offspring of parents with current mania/hypomania compared to offspring of parents in remission. Conversely, using the CBCL and comparing with parents who were in remission, parents with current depression reported significantly more externalizing psychopathology in offspring, whereas parents with current mania/hypomania reported more externalizing and internalizing psychopathology in their offspring. On the YSR, offspring of parents with current mania/hypomania had more internalizing psychopathology compared to offspring of parents in remission. Teacher's reports showed no between-group differences in rates of any psychopathology.

CONCLUSION

Parental active mood symptomatology, especially during a manic/hypomanic episode, significantly affects their reports of their offspring's psychopathology. Trained interviewers reduce potential report bias. Clinicians and studies assessing children's psychopathology should take into account parental current mood state.

Somatic complaints in anxious youth

This study examined (a) demographic and clinical characteristics associated with physical symptoms in anxiety-disordered youth and (b) the impact of cognitive-behavioral therapy (Coping Cat), medication (sertraline), their combination, and pill placebo on physical symptoms. Youth (N = 488, ages 7-17 years) with a principal diagnosis of generalized anxiety disorder, separation anxiety disorder, or social phobia participated as part of a multi-site, randomized controlled trial and received treatment delivered over 12 weeks. Diagnostic status, symptom severity, and impairment were assessed at baseline and week 12. The total number and severity of physical symptoms was associated with age, principal diagnosis, anxiety severity, impairment, and the presence of comorbid internalizing disorders. Common somatic complaints were headaches, stomachaches, head cold or sniffles, sleeplessness, and feeling drowsy or too sleepy. Physical symptoms decreased over the course of treatment, and were unrelated to treatment condition. Clinical implications and directions for future research are discussed (ClinicalTrials.gov number, NCT00052078).

Predicting Anxiety Diagnoses and Severity with the CBCL-A: Improvement Relative to Other CBCL Scales?

The Child Behavior Checklist (CBCL) is a widely used parent-report of child and adolescent behavior. We examined the ability of the CBCL-A scale, a previously published subset of CBCL items, to predict the presence of generalized anxiety disorder (GAD), separation anxiety disorder (SAD), and social phobia (SoP), as well as anxiety severity, among 488 youth randomized in the Child Anxiety Multimodal Study (CAMS). We predicted that the CBCL-A's unique inclusion of items related to somatic symptoms would better identify anxiety disorder and severity than other CBCL scales, given that somatic complaints are often key features of anxiety among youth. Results support the use of the anxiety-based CBCL subscales as first-line screeners for generally elevated symptoms of anxiety, rather than tools to identify specific anxiety disorders. Although somatic symptoms are often reported and included in diagnostic criteria for certain anxiety disorders (e.g., SAD, GAD), the unique combination of somatic and non-somatic symptoms for the CBCL-A subscale did not increase its ability to consistently predict the presence of specific anxiety disorders.

Collaborative care outcomes for pediatric behavioral health problems: a cluster randomized trial

OBJECTIVE

To assess the efficacy of collaborative care for behavior problems, attention-deficit/hyperactivity disorder (ADHD), and anxiety in pediatric primary care (Doctor Office Collaborative Care; DOCC).

METHODS

Children and their caregivers participated from 8 pediatric practices that were cluster randomized to DOCC (n = 160) or enhanced usual care (EUC; n = 161). In DOCC, a care manager delivered a personalized, evidence-based intervention. EUC patients received psychoeducation and a facilitated specialty care referral. Care processes measures were collected after the 6-month intervention period. Family outcome measures included the Vanderbilt ADHD Diagnostic Parent Rating Scale, Parenting Stress Index-Short Form, Individualized Goal Attainment Ratings, and Clinical Global Impression-Improvement Scale. Most measures were collected at baseline, and 6-, 12-, and 18-month assessments. Provider outcome measures examined perceived treatment change, efficacy, and obstacles, and practice climate.

RESULTS

DOCC (versus EUC) was associated with higher rates of treatment initiation (99.4% vs 54.2%; P < .001) and completion (76.6% vs 11.6%, P < .001), improvement in behavior problems, hyperactivity, and internalizing problems (P < .05 to .01), and parental stress (P < .05-.001), remission in behavior and internalizing problems (P < .01, .05), goal improvement (P < .05 to .001), treatment response (P < .05), and consumer satisfaction (P < .05). DOCC pediatricians reported greater perceived practice change, efficacy, and skill use to treat ADHD (P < .05 to .01).

CONCLUSIONS

Implementing a collaborative care intervention for behavior problems in community pediatric practices is feasible and broadly effective, supporting the utility of integrated behavioral health care services.

Disruptive mood dysregulation disorder and chronic irritability in youth at familial risk for bipolar disorder

OBJECTIVE

Disruptive mood dysregulation disorder (DMDD) is a new diagnosis in the DSM-5. Youth with a family history of bipolar disorder (BD) are at increased risk for BD and non-bipolar psychopathology. No studies to date have examined rates of DMDD among offspring of parents with BD. This study examines the risk for DMDD in offspring of parents with BD compared to community controls and considers rates of chronic irritability (independent of a DMDD diagnosis) across diagnoses in youth with parents with BD.

METHOD

Modified DMDD criteria were applied post hoc to 375 offspring of parents with BD and 241 offspring, aged 6 to 17 years, of community control parents. We calculated odds ratios using generalized linear mixed models. In addition, we explored associations with a severe chronic irritability phenotype and various diagnoses in the high-risk cohort.

RESULTS

Offspring of parents with BD were more likely to meet criteria for DMDD than were the offspring of community control parents (Odds ratio [OR] = 8.3, 6.7% vs. 0.8%), even when controlling for demographic variables and comorbid parental diagnoses (OR = 5.4). They also had higher rates of chronic irritability compared to community controls (12.5% vs. 2.5%, χ(2) = 18.8, p < .005). Within the offspring of parents with BD, the chronic irritability phenotype was frequently present in offspring with diagnoses of BD, depression, attention-deficit/hyperactivity disorder, and disruptive behavior disorders.

CONCLUSIONS

Like other non-BD diagnoses, family history of BD increases the risk for DMDD. Severe chronic irritability and temper tantrums are the core features of DMDD, and are associated with mood and behavioral disorders in youth at risk for BD.

Naturalistic follow-up of youths treated for pediatric anxiety disorders

IMPORTANCE

Pediatric anxiety disorders are highly prevalent and impairing and are considered gateway disorders in that they predict adult psychiatric problems. Although they can be effectively treated in the short term, data are limited on the long-term outcomes in treated children and adolescents, particularly those treated with medication.

OBJECTIVE

To determine whether acute clinical improvement and treatment type (i.e., cognitive behavioral therapy, medication, or their combination) predicted remission of anxiety and improvement in global functioning at a mean of 6 years after randomization and to examine predictors of outcomes at follow-up.

DESIGN, SETTING, AND PARTICIPANTS

This naturalistic follow-up study, as part of the Child/Adolescent Anxiety Multimodal Extended Long-term Study (CAMELS), was conducted at 6 academic sites in the United States and included 288 youths (age range, 11-26 years; mean age, 17 years). Youths were randomized to 1 of 4 interventions (cognitive behavioral therapy, medication, combination, or pill placebo) in the Child/Adolescent Anxiety Multimodal Study (CAMS) and were evaluated a mean of 6 years after randomization. Participants in this study constituted 59.0% of the original CAMS sample.

EXPOSURES

Participants were assessed by independent evaluators using a semistructured diagnostic interview to determine the presence of anxiety disorders, the severity of anxiety, and global functioning. Participants and their parents completed questionnaires about mental health symptoms, family functioning, life events, and mental health service use.

MAIN OUTCOMES AND MEASURES

Remission, defined as the absence of all study entry anxiety disorders. RESULTS Almost half of the sample (46.5%) were in remission a mean of 6 years after randomization. Responders to acute treatment were significantly more likely to be in remission (odds ratio, 1.83; 95% CI, 1.08-3.09) and had less severe anxiety symptoms and higher functioning; the assigned treatment arm was unrelated to outcomes. Several predictors of remission and functioning were identified.

CONCLUSIONS AND RELEVANCE

Youths rated as responders during the acute treatment phase of CAMS were more likely to be in remission a mean of 6 years after randomization, although the effect size was small. Relapse occurred in almost half (48%) of acute responders, suggesting the need for more intensive or continued treatment for a sizable proportion of youths with anxiety disorders.

24- and 36-week outcomes for the Child/Adolescent Anxiety Multimodal Study (CAMS)

OBJECTIVE

We report active treatment group differences on response and remission rates and changes in anxiety severity at weeks 24 and 36 for the Child/Adolescent Anxiety Multimodal Study (CAMS).

METHOD

CAMS youth (N = 488; 74% ≤ 12 years of age) with DSM-IV separation, generalized, or social anxiety disorder were randomized to 12 weeks of cognitive-behavioral therapy (CBT), sertraline (SRT), CBT+SRT (COMB), or medication management/pill placebo (PBO). Responders attended 6 monthly booster sessions in their assigned treatment arm; youth in COMB and SRT continued on their medication throughout this period. Efficacy of COMB, SRT, and CBT (n = 412) was assessed at 24 and 36 weeks postrandomization. Youth randomized to PBO (n = 76) were offered active CAMS treatment if nonresponsive at week 12 or over follow-up and were not included here. Independent evaluators blind to study condition assessed anxiety severity, functioning, and treatment response. Concomitant treatments were allowed but monitored over follow-up.

RESULTS

The majority (>80%) of acute responders maintained positive response at both weeks 24 and 36. Consistent with acute outcomes, COMB maintained advantage over CBT and SRT, which did not differ, on dimensional outcomes; the 3 treatments did not differ on most categorical outcomes over follow-up. Compared to COMB and CBT, youth in SRT obtained more concomitant psychosocial treatments, whereas those in SRT and CBT obtained more concomitant combined (medication plus psychosocial) treatment.

CONCLUSIONS

COMB maintained advantage over CBT and SRT on some measures over follow-up, whereas the 2 monotherapies remained indistinguishable. The observed convergence of COMB and monotherapy may be related to greater use of concomitant treatment during follow-up among youth receiving the monotherapies, although other explanations are possible. Although outcomes were variable, most CAMS-treated youth experienced sustained treatment benefit.

Dimensional psychopathology in preschool offspring of parents with bipolar disorder

BACKGROUND

The purpose of this study is to compare the dimensional psychopathology, as ascertained by parental report, in preschool offspring of parents with bipolar disorder (BP) and offspring of community control parents.

METHODS

122 preschool offspring (mean age 3.3 years) of 84 parents with BP, with 102 offspring of 65 control parents (36 healthy, 29 with non-BP psychopathology), were evaluated using the Child Behavior Checklist (CBCL), the CBCL-Dysregulation Profile (CBCL-DP), the Early Childhood Inventory (ECI-4), and the Emotionality Activity Sociability (EAS) survey. Teachers' Report Forms (TRF) were available for 51 preschoolers.

RESULTS

After adjusting for confounders, offspring of parents with BP showed higher scores in the CBCL total, externalizing, somatic, sleep, aggressive, and CBCL-DP subscales; the ECI-4 sleep problem scale; and the EAS total and emotionality scale. The proportion of offspring with CBCL T-scores ≥ 2 SD above the norm was significantly higher on most CBCL subscales and the CBCL-DP in offspring of parents with BP compared to offspring of controls even after excluding offspring with attention deficit hyperactivity disorder and/or oppositional defiant disorder. Compared to offspring of parents with BP-I, offspring of parents with BP-II showed significantly higher scores in total and most CBCL subscales, the ECI-4 anxiety and sleep scales and the EAS emotionality scale. For both groups of parents, there were significant correlations between CBCL and TRF scores (r = .32-.38, p-values ≤.02).

CONCLUSIONS

Independent of categorical axis-I psychopathology and other demographic or clinical factors in both biological parents, preschool offspring of parents with BP have significantly greater aggression, mood dysregulation, sleep disturbances, and somatic complaints compared to offspring of control parents. Interventions to target these symptoms are warranted.
