Four-Year Longitudinal Course of Children and Adolescents With Bipolar Spectrum Disorders: The Course and Outcome of Bipolar Youth (COBY) Study

OBJECTIVE The authors sought to assess the longitudinal course of youths with bipolar spectrum disorders over a 4-year period. METHOD At total of 413 youths (ages 7-17 years) with bipolar I disorder (N=244), bipolar II disorder (N=28), and bipolar disorder not otherwise specified (N=141) were enrolled in the study. Symptoms were ascertained retrospectively on average every 9.4 months for 4 years using the Longitudinal Interval Follow-Up Evaluation. Rates and time to recovery and recurrence and week-by-week symptomatic status were analyzed. RESULTS Approximately 2.5 years after onset of their index episode, 81.5% of the participants had fully recovered, but 1.5 years later 62.5% had a syndromal recurrence, particularly depression. One-third of the participants had one syndromal recurrence, and 30% had two or more. The polarity of the index episode predicted that of subsequent episodes. Participants were symptomatic during 60% of the follow-up period, particularly with subsyndromal symptoms of depression and mixed polarity, with numerous changes in mood polarity. Manic symptomatology, especially syndromal, was less frequent, and bipolar II was mainly manifested by depressive symptoms. Overall, 40% of the participants had syndromal or subsyndromal symptoms during 75% of the follow-up period, and 16% of the participants experienced psychotic symptoms during 17% the follow-up period. Twenty-five percent of youths with bipolar II converted to bipolar I, and 38% of those with bipolar disorder not otherwise specified converted to bipolar I or II. Early onset, diagnosis of bipolar disorder not otherwise specified, long illness duration, low socioeconomic status, and family history of mood disorders were associated with poorer outcomes. CONCLUSIONS Bipolar spectrum disorders in youths are characterized by episodic illness with subsyndromal and, less frequently, syndromal episodes with mainly depressive and mixed symptoms and rapid mood changes.

Sleep disturbance preceding completed suicide in adolescents.

We examined sleep difficulties preceding death in a sample of adolescent suicide completers as compared with a matched sample of community control adolescents. Sleep disturbances were assessed in 140 adolescent suicide victims with a psychological autopsy protocol and in 131 controls with a similar semistructured psychiatric interview. Rates of sleep disturbances were compared between groups. Findings indicate suicide completers had higher rates of overall sleep disturbance, insomnia, and hypersomnia as compared with controls within both the last week and the current affective episode. Group differences in overall sleep disturbance (both within the last week and present episode), insomnia (last week), and hypersomnia (last week) remained significant after controlling for the differential rate of affective disorder between groups. Similarly, overall sleep disturbance (last week and present episode) and insomnia (last week) distinguished completers in analyses accounting for severity of depressive symptoms. Only a small percentage of the sample exhibited changes in sleep symptom severity in the week preceding completed suicide, but of these, a higher proportion were completers. These findings support a significant and temporal relationship between sleep problems and completed suicide in adolescents. Sleep difficulties should therefore be carefully considered in prevention and intervention efforts for adolescents at risk for suicide.

Cognitive-behavioral therapy for suicide prevention (CBT-SP): treatment model, feasibility, and acceptability.

OBJECTIVE To describe the elements of a manual-based cognitive-behavioral therapy for suicide prevention (CBT-SP) and to report its feasibility in preventing the recurrence of suicidal behavior in adolescents who have recently attempted suicide. METHOD The CBT-SP was developed using a risk reduction and relapse prevention approach and theoretically grounded in principles of cognitive-behavioral therapy, dialectical behavioral therapy, and targeted therapies for suicidal youths with depression. The CBT-SP consists of acute and continuation phases, each lasting about 12 sessions, and includes a chain analysis of the suicidal event, safety plan development, skill building, psychoeducation, family intervention, and relapse prevention. RESULTS The CBT-SP was administered to 110 recent suicide attempters with depression aged 13 to 19 years (mean 15.8 years, SD 1.6) across five academic sites. Twelve or more sessions were completed by 72.4% of the sample. CONCLUSIONS A specific intervention for adolescents at high risk for repeated suicide attempts has been developed and manual based, and further testing of its efficacy seems feasible.

The Treatment of Adolescent Suicide Attempters Study (TASA): Predictors of Suicidal Events in an Open Treatment Trial

OBJECTIVE To identify the predictors of suicidal events and attempts in adolescent suicide attempters with depression treated in an open treatment trial. METHOD Adolescents who had made a recent suicide attempt and had unipolar depression (n =124) were either randomized (n = 22) or given a choice (n = 102) among three conditions. Two participants withdrew before treatment assignment. The remaining 124 youths received a specialized psychotherapy for suicide attempting adolescents (n = 17), a medication algorithm (n = 14), or the combination (n = 93). The participants were followed up 6 months after intake with respect to rate, timing, and predictors of a suicidal event (attempt or acute suicidal ideation necessitating emergency referral). RESULTS The morbid risks of suicidal events and attempts on 6-month follow-up were 0.19 and 0.12, respectively, with a median time to event of 44 days. Higher self-rated depression, suicidal ideation, family income, greater number of previous suicide attempts, lower maximum lethality of previous attempt, history of sexual abuse, and lower family cohesion predicted the occurrence, and earlier time to event, with similar findings for the outcome of attempts. A slower decline in suicidal ideation was associated with the occurrence of a suicidal event. CONCLUSIONS In this open trial, the 6-month morbid risks for suicidal events and for reattempts were lower than those in other comparable samples, suggesting that this intervention should be studied further. Important treatment targets include suicidal ideation, family cohesion, and sequelae of previous abuse. Because 40% of events occurred with 4 weeks of intake, an emphasis on safety planning and increased therapeutic contact early in treatment may be warranted.

Course of subthreshold bipolar disorder in youth: diagnostic progression from bipolar disorder not otherwise specified.

OBJECTIVE To determine the rate of diagnostic conversion from an operationalized diagnosis of bipolar disorder not otherwise specified (BP-NOS) to bipolar I disorder (BP-I) or bipolar II disorder (BP-II) in youth over prospective follow-up and to identify factors associated with conversion. METHOD Subjects were 140 children and adolescents recruited from clinical referrals or advertisement who met operationalized criteria for BP-NOS at intake and participated in at least one follow-up evaluation (91% of initial cohort). Diagnoses were assessed at follow-up interviews using the Longitudinal Interval Follow-Up Evaluation. The mean duration of follow-up was 5 years and the mean interval between assessments was 8.2 months. RESULTS Diagnostic conversion to BP-I or BP-II occurred in 63 subjects (45%): 32 (23%) to BP-I (nine of whom had initially converted to BP-II) and 31 to only BP-II (22%). Median time from intake to conversion was 58 weeks. First- or second-degree family history of mania or hypomania was the strongest baseline predictor of diagnostic conversion (p = .006). Over follow-up, conversion was associated with greater intensity of hypomanic symptoms and with greater exposure to specialized, intensive outpatient psychosocial treatments. There was no association between conversion and exposure to treatment with particular medication classes. CONCLUSIONS Children and adolescents referred with mood symptoms that meet operationalized criteria for BP-NOS, particularly those with a family history of BP, frequently progress to BP-I or BP-II. Efforts to identify these youth and effectively intervene may have the potential to curtail the progression of mood disorders in this high-risk population.

Psychosocial Functioning Among Bipolar Youth

BACKGROUND Evidence indicates that children and adolescents with bipolar disorder (BP) experience significant functional impairment. However, little is known about the association between psychosocial functioning and episodes of illness, demographic, and clinical variables in this population. METHODS Subjects included 446 patients aged 7 to 17 diagnosed with DSM-IV bipolar disorder via the K-SADS for the Course and Outcome of Bipolar Youth (COBY) study. The Psychosocial Functioning Schedule of the Adolescent Longitudinal Interval Follow-Up Assessment (A-LIFE) was administered at study intake. RESULTS Mild to moderate levels of psychosocial impairment were evident in work (includes academics), interpersonal, and overall domains of functioning among BP youth. Multivariate analyses indicated that the strongest predictors of psychosocial impairment were adolescence (regardless of age of onset), current mood episode, current affective symptom severity, current psychotic symptoms, and current comorbid conduct disorder. Bipolar youth in-episode were significantly more impaired than those in partial remission/recovery in every functional domain examined and were less satisfied with their functioning. Yet, BP youth in partial remission/recovery reported significant psychosocial impairment. LIMITATIONS Limitations include the reliance on patient and parent retrospective report of psychosocial functioning. Additionally, we did not account for the impact of psychosocial and pharmacological interventions on functioning. CONCLUSIONS Findings suggest pediatric BP is associated with significant impairment in psychosocial functioning during and between episodes, with greater impairment during mood episodes than during partial remission/recovery. Additionally, functional impairment in BP appears to increase during adolescence regardless of age of onset. Clinicians should carefully assess and address psychosocial impairment during and between mood episodes, with particular attention to the functioning of BP adolescents.

Substance Use Disorders among Adolescents with Bipolar Spectrum Disorders

OBJECTIVE We set out to examine the prevalence and correlates of substance use disorders (SUD) in a large sample of adolescents with bipolar disorder (BP). METHODS Subjects were 249 adolescents ages 12 to 17 years old who fulfilled DSM-IV criteria for bipolar I disorder [(BPI), n = 154], or bipolar II disorder [(BPII), n = 25], or operationalized criteria for BP not otherwise specified [(BP NOS), n = 70], via the Schedule for Affective Disorders and Schizophrenia for School-Aged Children (K-SADS). As part of the multi-site Course and Outcome of Bipolar Youth study, demographic, clinical, and family history variables were measured via intake clinical interview with the subject and a parent/guardian. RESULTS The lifetime prevalence of SUD among adolescents with BP was 16% (40/249). Results from univariate analyses indicated that subjects with, as compared to without, SUD were significantly less likely to be living with both biological parents, and that there was significantly greater lifetime prevalence of physical abuse, sexual abuse, suicide attempts, conduct disorder, and posttraumatic stress disorder among subjects with SUD. Subjects with SUD reported significantly greater 12-month prevalence of trouble with police, and females with SUD reported significantly greater 12-month prevalence of pregnancy and abortion. Significant predictors of SUD in a logistic regression model included living with both biological parents (lower prevalence), conduct disorder and suicide attempts (increased prevalence). In logistic regression analyses controlling for demographic differences and conduct disorder, SUD remained significantly associated with trouble with police, whereas the association of SUD with pregnancy and abortion was reduced to a statistical trend. The prevalence of SUD was not significantly different among child- versus adolescent-onset BP subjects. CONCLUSIONS SUD among adolescents with BP is associated with profound hazards including suicide attempts, trouble with police, and teenage pregnancy and abortion.

International Society for Bipolar Disorders Task Force on Suicide: meta-analyses and meta-regression of correlates of suicide attempts and suicide deaths in bipolar disorder.

Bipolar disorder is associated with a high risk of suicide attempts and suicide death. The main objective of the present study was to identify and quantify the demographic and clinical correlates of attempted and completed suicide in people with bipolar disorder.

The Child Behavior Checklist (CBCL) and the CBCL-Bipolar Phenotype Are Not Useful in Diagnosing Pediatric Bipolar Disorder

OBJECTIVES Previous studies have suggested that the sum of Attention, Aggression, and Anxious/Depressed subscales of Child Behavior Checklist (CBCL-PBD; pediatric bipolar disorder phenotype) may be specific to pediatric bipolar disorder (BP). The purpose of this study was to evaluate the usefulness of the CBCL and CBCL-PBD to identify BP in children <12 years old. METHODS A sample of children with BP I, II, and not otherwise specified (NOS) (n = 157) ascertained through the Course and Outcome for Bipolar Disorder in Youth (COBY) study were compared with a group of children with major depressive/anxiety disorders (MDD/ANX; n = 101), disruptive behavior disorder (DBD) (n = 127), and healthy control (HC) (n = 128). The CBCL T-scores and area under the curve (AUC) scores were calculated and compared among the above-noted groups. RESULTS Forty one percent of BP children did not have significantly elevated CBCL-PBD scores (>or=2 standard deviations [SD]). The sensitivity and specificity of CBCL-PBD >or= 2 SD for diagnosis of BP was 57% and 70-77%, respectively, and the accuracy of CBCL-PBD for identifying a BP diagnosis was moderate (AUC = 0.72-0.78). CONCLUSION The CBCL and the CBCL-PBD showed that BP children have more severe psychopathology than HC and children with other psychopathology, but they were not useful as a proxy for Diagnostic and Statistical Manual of Mental Disorders, 4(th) edition (DSM-IV) diagnosis of BP.

Prevalence and correlates of physical and sexual abuse in children and adolescents with bipolar disorder

OBJECTIVE Adult bipolar disorder (BP) has been associated with lifetime history of physical and sexual abuse. However, there are no reports of the prevalence of abuse in BP youth. The objective of this study was to examine the prevalence and correlates of physical and/or sexual abuse among youth with BP spectrum disorders. METHODS Four hundred forty-six youths, ages 7 to 17 years (12.7+/-3.2), meeting DSM-IV criteria for BP-I (n=260), BP-II (n=32) or operationalized definition of BP-NOS (n=154) were assessed using the Schedule for Affective Disorders and Schizophrenia for School Age Children-Present and Lifetime version (K-SADS-PL). Abuse was ascertained using the K-SADS. RESULTS Twenty percent of the sample experienced physical and/or sexual abuse. The most robust correlates of any abuse history were living with a non-intact family (OR=2.6), lifetime history of posttraumatic stress disorder (PTSD) (OR=8.8), psychosis (OR=2.1), conduct disorder (CD) (OR=2.3), and first-degree family history of mood disorder (OR=2.2). After adjusting for confounding demographic factors, physical abuse was associated with longer duration of BP illness, non-intact family, PTSD, psychosis, and first-degree family history of mood disorder. Sexual abuse was associated with PTSD. Subjects with both types of abuse were older, with longer illness duration, non-intact family, and greater prevalence of PTSD and CD as compared with the non-abused group. LIMITATIONS Retrospective data. Also, since this is a cross-sectional study, no inferences regarding causality can be made. CONCLUSION Sexual and/or physical abuse is common in youth with BP particularly in subjects with comorbid PTSD, psychosis, or CD. Prompt identification and treatment of these youth is warranted.
