State and Trait Mindfulness as Predictors of Skin Conductance Response to Stress.

Mindfulness is typically understood as non-judgmental, focused attention on the present moment, although it may be conceptualized as a state, a trait, and an outcome of intervention. There is a limited understanding of the physiological effects of state and trait mindfulness, and it has been a challenge to the research community to measure these effects. This study examined whether state and trait mindfulness are associated with reduced stress response activation in healthy young adults.

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).

Increased cerebral blood flow among adolescents with bipolar disorder at rest is reduced following acute aerobic exercise.

Objective: Cerebral blood flow (CBF) is altered in mood disorders but has not been examined among adolescents with bipolar disorder (BD). Similarly, little is known about the acute neurophysiologic effects of aerobic exercise in BD. We therefore compared CBF between adolescents with and without BD at rest and acutely following a single exercise session.

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.

Characterizing exercise-induced feelings after one bout of exercise among adolescents with and without bipolar disorder.

Background: Exercise may be a practical, non-pharmacological strategy for symptom and health management for adolescents with bipolar disorder (BD). The purpose of this study was to determine if adolescents with BD experience changes in exercise-induced feelings from one bout of exercise similar to their otherwise healthy peers.

Methods: Thirty-two adolescents with BD (Age (SD)=16.

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).
