The Resilient Youth Program: a promising skills-based online program for resiliency and stress management.

BACKGROUND: Prevention programs that target resilience may help youth address mental health difficulties and promote well-being during public health crises. AIMS: To examine the preliminary efficacy of the Resilient Youth Program (RYP). METHOD: The RYP was delivered remotely from a US academic medical centre to youth in the community via a naturalistic pilot study. Data from 66 youth (ages 6-18, Mage = 11.65, SD = 3.02) and their parents were collected via quality assurance procedures (May 2020 to March 2021). Pre/post-intervention child/parent-reported psychological and stress symptoms as well as well-being measures were compared via Wilcoxon signed rank tests. Child/parent-reported skills use data were collected. RESULTS: Among child-reported outcomes, there were significant decreases in physical stress (p = .03), anxiety (p = .004), depressive symptoms (p < .001) and anger (p = .002), as well as increased life satisfaction (p = .02). There were no significant differences in child-reported psychological stress (p = .06) or positive affect (p = .09). Among parent-reported child outcomes, there were significant decreases in psychological (p < .001) and physical stress (p = .03), anxiety (p < .001), depressive symptoms (p < .001), and anger (p < .002) as well as increased positive affect (p < .001) and life satisfaction (p < .001). Effect sizes ranged from small to medium; 77% of youth (73% of parents) reported using RYP skills. Age and gender were not associated with outcome change. CONCLUSIONS: The RYP may help reduce psychological/stress symptoms and increase well-being among youth; further research is needed.

Early risk factors for psychopathology in offspring of parents with bipolar disorder: the role of obstetric complications and maternal comorbid anxiety.

OBJECTIVE: Offspring of parents with bipolar disorder (BD) are at increased risk for developing a range of psychiatric disorders. Although genetic factors clearly confer risk to offspring, environmental factors also play a role in increasing vulnerability. Such environmental factors may occur at the initial stages of development in the form of obstetric complications (OCs). The current investigation examined the relationship between OCs and the development of psychopathology in offspring at risk for BD and the influence of parental psychopathology in this relationship. METHODS: This cross-sectional study included 206 offspring of 119 parents with BD. Probit regression analyses examined associations between: (1) OC history and offspring psychopathology; and (2) maternal lifetime comorbid anxiety diagnoses and OCs in pregnancy/delivery with their offspring. Path analyses then tested whether OCs mediate the relationship between maternal comorbid anxiety disorders and offspring lifetime psychopathology. RESULTS: Results indicated a specific association between OCs, particularly delivery complications, and increased risk for offspring anxiety disorders. Data also showed a significant relationship between maternal anxiety disorder comorbidity and OCs. Finally, path analyses suggested that delivery complications act as a mediator in the relationship between comorbid maternal anxiety disorder and offspring anxiety disorder. CONCLUSIONS: Our findings lend support to the importance of identifying and reducing anxiety in pregnant woman with BD. The identification of OCs as early vulnerability factors for psychopathology in offspring at familial risk may also lead to earlier detection and intervention in these offspring.

Anxiety and Disruptive Behavior Symptoms and Disorders in Preschool-Age Offspring of Parents With and Without Bipolar Disorder: Associations With Parental Comorbidity.

OBJECTIVE: We examined the relative contribution of parental bipolar disorder (BPD) and psychiatric comorbidities (disruptive behavior disorders [DBD] and anxiety disorders) in predicting psychiatric symptoms and disorders in 2-5-year-old offspring. METHODS: Participants were 60 families with a parent with BPD and 78 offspring and 70 comparison families in which neither parent had a mood disorder and 91 offspring. Parent and offspring diagnoses and symptoms were assessed using standardized diagnostic interviews and measures, with offspring assessors masked to parental diagnoses. RESULTS: Offspring of parents with BPD had significant elevations in behavioral, mood and anxiety disorders and symptoms. Both parental BPD and DBD contributed to elevations in child disruptive behavioral symptoms, whereas child anxiety symptoms were more strongly predicted by comorbid parental anxiety. Parental BPD was a stronger predictor than comorbid DBD of child DBDs. CONCLUSION: Some of the elevated risk for disorders in preschoolers is accounted for by parental comorbidity.

Examining the association between stimulant treatment and cognitive outcomes across the life cycle of adults with attention-deficit/hyperactivity disorder: a controlled cross-sectional study.

Few studies have evaluated the effects of stimulants on cognition in adults with attention-deficit/hyperactivity disorder (ADHD). We evaluated the impact of stimulant treatment on neurocognition in a cross-sectional sample of adults with ADHD. Comparisons were made between adults with ADHD who received (n = 105) and who had never received pharmacotherapy (n = 116) and 146 controls. The subjects were assessed cross-sectionally using a structured diagnostic interview and a neurocognitive battery. We modeled cognitive measures as a function of age and group status using linear regression. Treated ADHD subjects had statistically significantly better scores on measures of IQ than did untreated ones. The treated group also had better (not statistically significant) scores on neuropsychological measures. The direction of the effects of stimulant on neurocognition suggests that either good cognitive functioning may be a determinant of seeking treatment or that stimulant treatment may improve cognition in adults with ADHD. However, this does not indicate a clear causal relationship.

Reward-Related Neural Circuitry in Depressed and Anxious Adolescents: A Human Connectome Project.

OBJECTIVE: Although depression and anxiety often have distinct etiologies, they frequently co-occur in adolescence. Recent initiatives have underscored the importance of developing new ways of classifying mental illness based on underlying neural dimensions that cut across traditional diagnostic boundaries. Accordingly, the aim of the study was to clarify reward-related neural circuitry that may characterize depressed-anxious youth. METHOD: The Boston Adolescent Neuroimaging of Depression and Anxiety Human Connectome Project tested group differences regarding subcortical volume and nucleus accumbens activation during an incentive processing task among 14- to 17-year-old adolescents presenting with a primary depressive and/or anxiety disorder (n = 129) or no lifetime history of mental disorders (n = 64). In addition, multimodal modeling examined predictors of depression and anxiety symptom change over a 6-month follow-up period. RESULTS: Our findings highlighted considerable convergence. Relative to healthy youth, depressed-anxious adolescents exhibited reduced nucleus accumbens volume and activation following reward receipt. These findings remained when removing all medicated participants (∼59% of depressed-anxious youth). Subgroup analyses comparing anxious-only, depressed-anxious, and healthy youth also were largely consistent. Multimodal modeling showed that only structural alterations predicted depressive symptoms over time. CONCLUSION: Multimodal findings highlight alterations within nucleus accumbens structure and function that characterize depressed-anxious adolescents. In the current hypothesis-driven analyses, however, only reduced nucleus accumbens volume predicted depressive symptoms over time. An important next step will be to clarify why structural alterations have an impact on reward-related processes and associated symptoms.

Impact of executive function deficits in youth with bipolar I disorder: a controlled study.

Although psychometrically-defined executive function deficits (EFDs) and ecologically valid functional outcomes have been documented among youth with bipolar I (BP-I) disorder, little is known about their association. We hypothesized that EFDs would be associated with significant ecologically valid impairments beyond those predicted by having BP-I disorder. Youth with BP-I disorder were ascertained from psychiatric clinics and community sources. We defined EFDs as having at least two out of eight EF measures impaired from a battery of six tests. Significantly more youth with BP-I disorder had EFDs than controls (45% versus 17%). Comparisons were made between controls without EFDs (N=81), controls with EFDs (N=17), BP-I youth without EFDs (N=76), and BP-I youth with EFDs (N=62). EFDs were associated with an increased risk for placement in a special class and a decrease in academic achievement (WRAT-3 reading and arithmetic). EFDs in BP-I subjects were associated with an increased risk for speech/language disorder (as assessed in the K-SADS-E) relative to BP-I subjects without EFDs. Youth with BP-I disorder and EFDs are at high risk for significant impairments in academic functioning.

Discriminant and concurrent validity of a simplified DSM-based structured diagnostic instrument for the assessment of autism spectrum disorders in youth and young adults.

BACKGROUND: To evaluate the concurrent and discriminant validity of a brief DSM-based structured diagnostic interview for referred individuals with autism spectrum disorders (ASDs). METHODS: To test concurrent validity, we assessed the structured interview's agreement in 123 youth with the expert clinician assessment and the Social Responsiveness Scale (SRS). Discriminant validity was examined using 1563 clinic-referred youth. RESULTS: The structured diagnostic interview and SRS were highly sensitive indicators of the expert clinician assessment. Equally strong was the agreement between the structured interview and SRS. We found evidence for high specificity for the structured interview. CONCLUSIONS: A simplified DSM-based ASD structured diagnostic interview could serve as a useful diagnostic aid in the assessment of subjects with ASDs in clinical and research settings.

Further Evidence that Subsyndromal Manifestations of Depression in Childhood Predict the Subsequent Development of Major Depression: A Replication Study in a 10 Year Longitudinally Assessed Sample.

BACKGROUND: We have previously shown that subsyndromal scores on the Child Behavior Checklist (CBCL)-Anxiety/Depression (Anx/Dep) scale at baseline predicted the subsequent development of Major Depressive Disorder (MDD) in youth with ADHD. The present study aimed to replicate these findings in a separate, long-term, longitudinal sample of children at high- and low- risk for depression. METHODS: 219 children of parents with and without depression and/or anxiety, ages 2-25, were stratified into 3 groups: 1) children with familial risk for depression (by presence of parental MDD) plus subsyndromal scores on the CBCL-Anx/Dep scale, 2) children with familial risk for depression without subsyndromal scores, and 3) children with neither familial risk for depression nor subsyndromal scores. Subjects were reassessed at both 5 and 10 year follow-ups. RESULTS: Children with both subsyndromal scores on the CBCL-Anx/Dep plus a familial risk for depression were at greater risk for developing MDD at the 10 year follow-up when compared with all other groups. Those with familial risk but no subsyndromal scores had an intermediate risk that was greater than the controls, who had the lowest risk. LIMITATIONS: The recruitment of the study included families with parental panic disorder, so the sample likely included more families with anxiety disorders than the general population. CONCLUSIONS: Our results showed that subsyndromal scores of the CBCL-Anx/Dep scale increased the risk for the subsequent development of MDD, particularly in children at high risk for depression. These results confirm the CBCL-Anx/Dep scale's utility in identifying children at high risk for developing MDD.

Image acquisition and quality assurance in the Boston Adolescent Neuroimaging of Depression and Anxiety study.

The Connectomes Related to Human Diseases (CRHD) initiative was developed with the Human Connectome Project (HCP) to provide high-resolution, open-access, multi-modal MRI data to better understand the neural correlates of human disease. Here, we present an introduction to a CRHD project, the Boston Adolescent Neuroimaging of Depression and Anxiety (BANDA) study, which is collecting multimodal neuroimaging, clinical, and neuropsychological data from 225 adolescents (ages 14-17), 150 of whom are expected to have a diagnosis of depression and/or anxiety. Our transdiagnostic recruitment approach samples the full spectrum of depressed/anxious symptoms and their comorbidity, consistent with NIMH Research Domain Criteria (RDoC). We focused on an age range that is critical for brain development and for the onset of mental illness. This project sought to harmonize imaging sequences, hardware, and functional tasks with other HCP studies, although some changes were made to canonical HCP methods to accommodate our study population and questions. We present a thorough overview of our imaging sequences, hardware, and scanning protocol. We detail similarities and differences between this study and other HCP studies. We evaluate structural-, diffusion-, and functional-image-quality measures that may be influenced by clinical factors (e.g., disorder, symptomatology). Signal-to-noise and motion estimates from the first 140 adolescents suggest minimal influence of clinical factors on image quality. We anticipate enrollment of an additional 85 participants, most of whom are expected to have a diagnosis of anxiety and/or depression. Clinical and neuropsychological data from the first 140 participants are currently freely available through the National Institute of Mental Health Data Archive (NDA).

Examination of concordance between maternal and youth reports in the diagnosis of pediatric bipolar disorder.

OBJECTIVE: While concordance between mother and child report continues to be the gold standard in the assessment of pediatric bipolar disorder, uncertainty develops when a mother's report is not endorsed by the youth. To this end we compared discordant (mother positive and youth negative) and concordant (mother and youth positive) cases. METHODS: Subjects were 98 adolescents (12-19 years of age) derived from family studies of bipolar disorder in youth who had both self-reported and mother-reported assessments. Comparisons were made between discordant (n = 35) and concordant (n = 59) cases on a wide range of clinical correlates. RESULTS: Mothers in both groups reported similar rates of symptoms of mania and depression. Within the concordant group, mothers and youth reported similar rates of symptoms of mania. There were no differences between the concordant and discordant groups in onset, duration, or impairment of mania, rates of psychiatric hospitalization, cognitive variables, or rates of disorders in family members. CONCLUSIONS: The similarities between discordant and concordant reports in symptomatology of mania and depression, rates of comorbidities, treatment needs, and other clinical correlates suggest that a mother-based diagnosis of mania should not be discounted in discrepant cases in which the youth fails to endorse the diagnosis.

Executive functioning in offspring at risk for depression and anxiety.

BACKGROUND: Executive functioning deficits (EFDs) have been found in adults with major depression and some anxiety disorders, yet it is unknown whether these deficits predate onset of disorder, or whether they reflect acute symptoms. Studies of at-risk offspring can shed light on this question by examining whether EFDs characterize children at high risk for depression and anxiety who are not yet symptomatic. METHODS: This study examined neuropsychological functioning in a sample of 147 children, ages 6-17 years (M age=9.16, SD=1.82), of parents with major depression (MDD) and/or panic disorder (PD) and of controls with neither disorder. Children were assessed via structured diagnostic interviews and neuropsychological measures. RESULTS: Although parental MDD and PD were not associated with neuropsychological impairments, presence of current offspring MDD was associated with poorer performance on several executive functioning and processing speed measures. Children with current generalized anxiety showed poorer verbal memory, whereas children with social phobia had more omissions on a continuous performance task. CONCLUSIONS: Findings suggest that EFDs do not serve as trait markers for developing anxiety or depression but appear to be symptomatic of current disorder.

Very early family-based intervention for anxiety: two case studies with toddlers.

Anxiety disorders represent the most common category of psychiatric disorder in children and adolescents and contribute to distress, impairment and dysfunction. Anxiety disorders or their temperamental precursors are often evident in early childhood, and anxiety can impair functioning, even during preschool age and in toddlerhood. A growing number of investigators have shown that anxiety in preschoolers can be treated efficaciously using cognitive-behavioural therapy (CBT) administered either by training the parents to apply CBT strategies with their children or through direct intervention with parents and children. To date, most investigators have drawn the line at offering direct CBT to children under the age of 4. However, since toddlers can also present with impairing symptoms, and since behaviour strategies can be applied in older preschoolers with poor language ability successfully, it ought to be possible to apply CBT for anxiety to younger children as well. We therefore present two cases of very young children with impairing anxiety (ages 26 and 35 months) and illustrate the combination of parent-only and parent-child CBT sessions that comprised their treatment. The treatment was well tolerated by parents and children and showed promise for reducing anxiety symptoms and improving coping skills.

High risk studies and developmental antecedents of anxiety disorders.

The past two decades have witnessed significant growth in our understanding of the developmental antecedents of anxiety disorders. In this article, we review studies of offspring at risk for anxiety disorders, longitudinal studies of the course of anxiety disorders in clinical, epidemiologic, and at-risk samples, studies of hypothesized temperamental risk factors for anxiety, and give a brief overview of the literature on environmental risk factors. Clear developmental antecedents to anxiety disorders identified include (1) childhood anxiety disorders [in particular, separation anxiety and overanxious disorder/general anxiety disorder (GAD)], (2) behavioral inhibition which predicts later social phobia, (3) anxiety sensitivity which predicts later panic disorder, and (4) negative affectivity, which predicts a spectrum of psychopathology including anxiety disorders. Further prospective studies are needed to examine the roles of environmental factors such as parenting practices, peer influences, stressful life events, and perinatal stressors. Future studies could benefit from (1) beginning earlier in development and following individuals into adulthood, (2) assessing the overlap between multiple temperamental constructs, (3) greater use of observational measures of temperament and of parent-child and peer interactions, (4) greater attention to parental psychopathology which may confound associations noted, (5) exploration of other features of anxiety disorders (neurofunctional correlates, cognitive features, other aspects of emotional regulation) as potential precursors, and (6) intervention studies exploring whether modifying developmental antecedents can alter the course of anxiety disorders.

Further evidence of an association between adolescent bipolar disorder with smoking and substance use disorders: a controlled study.

Although previous work suggests that juvenile onset bipolar disorder increases risk for substance use disorders and cigarette smoking, the literature on the subject is limited. We evaluated the association of risk for substance use disorders and cigarette smoking with bipolar disorder in adolescents in a case-control study of adolescents with bipolar disorder (n=105, age 13.6+/-2.5 years [mean]; 70% male) and without bipolar disorder ("controls"; n=98, age 13.7+/-2.1 years; 60% male). Rates of substance use and other disorders were assessed with structured interviews (KSADS-E for subjects younger than 18, SCID for 18-year-old subjects). Bipolar disorder was associated with a significant age-adjusted risk for any substance use disorder (hazard ratio[95% confidence interval]=8.68[3.02 25.0], chi(2)=16.06, p<0.001, df=1), alcohol abuse (7.66 [2.20 26.7], chi(2)=10.2, p=0.001, df=1), drug abuse (18.5 [2.46 139.10], chi(2)=8.03, p=0.005, df=1) and dependence (12.1 [1.54 95.50], chi(2)=5.61, p=0.02, df=1), and cigarette smoking (12.3 [2.83 53.69], chi(2)=11.2, p<0.001, df=1), independently of attention deficit/hyperactivity disorder, multiple anxiety, and conduct disorder (CD). The primary predictor of substance use disorders in bipolar youth was older age (BPD-SUD versus BPD+SUD, logistic regression: chi(2)=89.37, p<0.001). Adolescent bipolar disorder is a significant risk factor for substance use disorders and cigarette smoking, independent of psychiatric comorbidity. Clinicians should carefully screen adolescents with bipolar disorder for substance and cigarette use.

Disruptive behavior disorders in offspring of parents with major depression: associations with parental behavior disorders.

OBJECTIVE: Although the offspring of parents with major depressive disorder (MDD) are at increased risk to develop disruptive behavior disorders (DBD) in addition to MDD, it remains unclear whether this heightened risk is due to MDD or to comorbid DBD in the parents. METHOD: In a secondary analysis of longitudinal data from offspring at risk for MDD and panic disorder and comparison children, we stratified 169 children of parents who had been treated for MDD based upon presence (n=50) or absence (n=119) of parental history of DBD (ADHD, oppositional disorder, and conduct disorder) and contrasted them with children of parents with DBD but without MDD (n=19) and children whose parents had neither MDD nor DBD (n=106). The children had been assessed in middle childhood using structured diagnostic interviews. RESULTS: Offspring of parents with MDD + DBD had significantly higher rates of MDD, DBD in general, and ADHD in particular, compared with offspring of parents with MDD alone. Offspring of parents with MDD + DBD also had higher rates of mania than controls. Both parental MDD and DBD conferred independent risk for MDD and DBD in the offspring. However, only parental DBD conferred independent risk for conduct disorder and ADHD and only parental MDD conferred independent risk for oppositional defiant disorder. CONCLUSION: Elevated rates of DBD in the offspring of parents with MDD appear to be due in part to the presence of DBD in the parents. Further studies of samples not selected on the basis of parental panic disorder are needed to confirm these results.

The child behavior checklist broad-band scales predict subsequent psychopathology: A 5-year follow-up.

OBJECTIVE: To evaluate the utility of the Child Behavior Check list (CBCL) for identifying children of parents with panic disorder or major depression at high-risk for future psychopathology. METHODS: Baseline Internalizing and Externalizing CBCL T-scores were used to predict subsequent depressive, anxiety, and disruptive behavior disorders at a 5-year follow-up in children of parents with panic disorder, major depression, or neither disorder. RESULTS: The Internalizing scale predicted subsequent agoraphobia, generalized anxiety disorder, separation anxiety disorder, and social phobia. In contrast, the Externalizing scale predicted subsequent disruptive behavior disorders and major depression. CONCLUSIONS: The convergence of these results with previous findings based on structured diagnostic interviews suggests that the CBCL broad-band scales can inexpensively and efficiently help identify children at high risk for future psychopathology within a population of children already at risk by virtue of parental psychopathology.

Association of bipolar and substance use disorders in parents of adolescents with bipolar disorder.

BACKGROUND: We have previously shown that juvenile bipolar disorder (BPD) is a risk for substance use disorders (SUD). Here we examine the expression of both disorders in families of youth with BPD to evaluate the familial risk mechanism. METHODS: We studied 108 adolescent BPD probands with 187 parents (34 with SUD and 58 parents) and 96 control probands with 177 parents with structured interviews. We compared the prevalence of BPD and SUD with Cox proportional hazards models with time to onset of BPD or SUD as the dependent variable and proband diagnosis (Control, BPD, or BPD+SUD) as the independent variable. RESULTS: The parents of the proband youth with BPD (without SUD) and BPD+SUD were more likely to develop BPD than the parents of control subjects [omnibus test chi2=10.18, p=.006]; we found no differences between the two bipolar groups. Parents of proband youth with BPD and with BPD+SUD were more likely than relatives of control subjects to develop SUD [omnibus test chi2=14.69, p<.001]; however, we found no differences between the parents of the two proband bipolar groups. Within the parents of proband youth with BPD+SUD, we found higher risk of SUD in parents with BPD than in those without BPD [chi2=8.39, p=.004], although the frequency of BPD was low in this group of parents. CONCLUSIONS: Bipolar disorder and SUD are prevalent in the first-degree relatives of adolescents with BPD. Adults with BPD were more likely to manifest SUD with preliminary evidence of BPD and SUD cosegregation.

Clinical outcomes of laboratory-observed preschool behavioral disinhibition at five-year follow-up.

BACKGROUND: Behavioral disinhibition refers to a temperamental tendency to exhibit boldness, approach, and spontaneity in unfamiliar situations. We previously found it to be associated with childhood disruptive behavior and mood disorders, as well as with parental bipolar disorder. In the present study, our objective was to examine the diagnostic outcome in middle childhood of behavioral disinhibition assessed at preschool age among offspring at risk for anxiety and mood disorders. METHODS: The sample consisted of 284 children, including offspring of parents with panic disorder or major depression and comparison offspring of parents without these disorders, who had been assessed with laboratory observations of temperament at ages 21 months to 6 years. We reassessed 215 of the children (77%) at 5-year follow-up (mean age 9.6 years) with structured diagnostic interviews. RESULTS: Compared with noninhibited, nondisinhibited control subjects, behaviorally disinhibited children had higher lifetime rates of comorbid mood plus disruptive behavior disorders and higher current rates of any disruptive behavior disorder and of oppositional defiant disorder. CONCLUSIONS: Behavioral disinhibition appears to be a temperamental antecedent of disruptive behavior disorders and their comorbidity with mood disorders in middle childhood, which may be targeted for preventive intervention.

Can bipolar disorder-specific neuropsychological impairments in children be identified?

This study examined neuropsychological deficits among children with bipolar disorder while attending to its comorbidity with attention-deficit/hyperactivity disorder (ADHD). Seventy-three unmedicated children (ages 6-17 years) with Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994) bipolar disorder plus ADHD (BPD + ADHD) were compared with 102 unmedicated children with ADHD without bipolar disorder, and 120 children without bipolar disorder or ADHD. Ninety-four percent of participants were Caucasian, 58% were male, and 42% were female. On average participants were of middle to upper socioeconomic status. Participants were assessed with a comprehensive neuropsychological battery and measures of academic achievement, school failure, and special education placement. Participants with BPD + ADHD and with ADHD were impaired in interference control, verbal learning, and arithmetic achievement and had higher rates of special school services. Across all of the measures of neuropsychological functioning, the only difference observed between youths with BPD + ADHD and youths with ADHD was that youths with BPD + ADHD performed more poorly on one measure of processing speed. Thus, comorbidity with ADHD may account for many of the neuropsychological deficits observed in children with bipolar disorder.

Childhood antecedent disorders to bipolar disorder in adults: a controlled study.

OBJECTIVE: The aim of the study was to examine antecedent childhood psychiatric disorders in adult patients with bipolar disorder. METHOD: Using structured diagnostic interviews, childhood psychiatric diagnoses of 83 referred patients with diagnosed DSM-IV bipolar disorder were compared to those of 308 adults without mood disorders. RESULTS: Patients with bipolar disorder had significantly higher rates of childhood disruptive behavior disorders (ADHD, oppositional-defiant disorder, and conduct disorder), childhood anxiety disorders (separation anxiety and overanxious disorder), and enuresis, compared to patients without mood disorders. The presence of these childhood disorders was associated with an earlier age of onset of bipolar illness. LIMITATIONS: The retrospective nature of the study may have affected both the rates of disorders recalled, as well as the ages of onset of disorders. Different referral sources for bipolar and comparison participants may have also impacted findings. CONCLUSIONS: Bipolar disorder in adults is frequently preceded by childhood disruptive behavior and anxiety disorders. These childhood disorders may be important markers of risk for adult bipolar disorder.
