Factors Associated With Sleep Disturbance Amongst Youth With Bipolar Disorder.

Background: While sleep disturbances and their impact on functioning are well-established in adults with bipolar disorder (BD), little is known about this topic in youth.

Objective: This study investigates the prevalence and correlates of sleep disturbance among youth with BD.

Methods: The study included 103 youth (72 BD, 31 healthy controls [HC]), ages 14-20 years.

Prevalence and correlates of childhood-onset bipolar disorder among adolescents.

Aim: Early-onset bipolar disorder (BD) is associated with a more severe illness as well as a number of clinical factors among adults. Early-onset can be categorized as childhood- (age < 13) or adolescent- (age ≥ 13) onset, with the two displaying different clinical profiles. We set out to examine differences in clinical, and familial characteristics among adolescents with childhood- versus adolescent-onset BD.

Comorbid Eating Disorders in a Sample of Youth With Bipolar Disorder: Elevated Burden of Dimensional and Categorical Psychopathology.

There is growing recognition of the importance of comorbid eating disorders (ED) among individuals with bipolar disorder (BD). However, most studies on this topic have focused on adult samples, and little is known regarding comorbid ED among youth with BD. The sample included 197 youth with BD (BD-I, BD-II, or BD-NOS [not otherwise specified]), aged 13-20 years and recruited from a subspecialized clinic within a tertiary academic health sciences center from 2009 to 2017.

Prevalence and correlates of police contact amongst youth with bipolar disorder.

Objectives: While multiple studies have examined prevalence and correlates of police contact in adults with bipolar disorder (BD), literature on this topic in youth is sparse. We therefore examined the prevalence and correlates of police contact amongst youth with BD.

Methods: The study included 197 youth with BD and 127 healthy controls, ages 14-20 years.

Clinical correlates of socioeconomic status in adolescent bipolar disorder.

Background: Lower socioeconomic status (SES) is associated with symptomatic severity, comorbidity, and functional impairment in adults with bipolar disorder (BD). Little is known about clinical correlates of SES in adolescents with BD.

Methods: Participants included 195 adolescents, 13-20 years old, with BD type I, II or not otherwise specified (NOS).

Similarities and Differences Across Bipolar Disorder Subtypes Among Adolescents.

To compare demographic, clinical, and familial characteristics across bipolar disorder (BD) subtypes in adolescents. A total of 168 participants, 13 to 19 years of age, with BD-I ( = 41), BD-II ( = 68), or operationalized BD-not otherwise specified (NOS) ( = 59) were recruited from a tertiary subspecialty clinic at an academic health sciences center. Diagnoses were determined using the semistructured K-SADS-PL (Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version) interview.

Dimensional and Categorical Correlates of Substance Use Disorders among Canadian Adolescents with Bipolar Disorder.

Objectives: Despite increasing evidence of excessive substance use disorder (SUD) prevalence among adolescents with bipolar disorder (BP), little is known about this topic among Canadian adolescents with BP. We therefore sought to examine the clinical characteristics and dimensional measures of psychopathology associated with comorbid SUD among Canadian BP adolescents.

Method: Participants were 100 adolescents, ages 13-19 years, with BP I, II, or not otherwise specified (NOS).

Binge eating and emotional eating behaviors among adolescents and young adults with bipolar disorder.

Background: This study investigates nutritional behavior among adolescents and young adults with bipolar disorder (BP) in comparison to those without history of major psychiatric disorder.

Methods: 131 participants (82 BP, 49 controls) with a mean age of 16.11 ± 1.

Prevalence and Correlates of Disruptive Mood Dysregulation Disorder Among Adolescents with Bipolar Disorder.

Objective: The purpose of this study was to examine the prevalence and correlates of disruptive mood dysregulation disorder phenotype (DMDDP) in a clinical population of adolescents with bipolar disorder (BD).

Methods: DMDD criteria were modified and applied to a sample of 116 adolescents with BD-I (n = 30), BD-II (n = 46) or BD-not otherwise specified (NOS) (n = 40) from a tertiary teaching hospital. Diagnoses were determined via the Kiddie Schedule for Affective Disorders and Schizophrenia for School-Aged Children, Present and Lifetime version (KSADS-PL).

Correlates of Adolescent-reported and Parent-reported Family Conflict Among Canadian Adolescents With Bipolar Disorder.

Background: Family conflict exacerbates the course of bipolar disorder (BP) among adults. However, few studies have examined family conflict among adolescents with BP, and fewer have looked at adolescent-reported and parent-reported family conflict separately.

Methods: Subjects were 89 adolescents, aged 13 to 19 years, with a diagnosis of BP on the basis of the Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version (KSADS-PL).

Controlled Study of Obesity Among Adolescents with Bipolar Disorder.

Objective: Despite numerous studies regarding obesity (OB) in adult bipolar disorder (BP), there are few studies on this topic among adolescents. The current study attempts to extend the literature on prevalence and correlates of OB in adolescent BP by including control participants, and determining OB by direct measurement.

Methods: Participants were 75 treatment-seeking adolescents, ages 13-19 years, with BP-I, -II, or -not otherwise specified, and 47 adolescents without major psychiatric illness.

Significance of borderline personality-spectrum symptoms among adolescents with bipolar disorder.

Background: Little is known regarding correlates of borderline personality-spectrum symptoms (BPSS) among adolescents with bipolar disorder (BP).

Methods: Participants were 90 adolescents, 13-19 years of age, who fulfilled DSM-IV-TR criteria for BP using semi-structured diagnostic interviews. BPSS status was ascertained using the Life Problems Inventory which assessed identity confusion, interpersonal problems, impulsivity, and emotional lability.

Correlates of psychiatric hospitalization in a clinical sample of Canadian adolescents with bipolar disorder.

Objective: To identify factors associated with psychiatric hospitalization among adolescents with bipolar disorder (BD).

Methods: Participants were 100 adolescents, ages 13-19, who fulfilled DSM-IV criteria for bipolar I disorder [(BD-I), n=26], bipolar II disorder [(BD-II), n=40], or operationalized criteria for BD not otherwise specified [(BD-NOS), n=34], via the Schedule for Affective Disorders and Schizophrenia, Present and Lifetime version (KSADS-PL). Demographic, clinical, and family history variables were measured via clinical interview with the participant and a parent or guardian.

Clinical characteristics associated with lithium use among adolescents with bipolar disorder.

Objective: Little is known regarding demographic and/or clinical characteristics associated with the use of lithium among adolescents with bipolar disorder (BP) in naturalistic clinical settings. We therefore examined factors associated with lithium among adolescents with BP presenting to a tertiary outpatient clinic.

Methods: Participants were 100 adolescents 13-19 years of age, with BP-I, BP-II, or BP not otherwise specified (BP-NOS).
