Children’s Mental HealthChildren’s Mental Health5,000,000 (the number of children and adolescents in the U.S.

suffer from a serious mental disorder resulting in significant functional impairments at home, at school, and with peers.)

80% (America’s youth with mental health needs who fail to be identified and to receive treatment and services.)

6-8 years – from onset to treatment for mood disorders

CONSEQUENCES (of untreated mental disorders include suicide, addictions, school failure, and criminal involvement).

Information obtained from National Alliance on Mental Illness web site Aug. 2007

Society benefits when Mental Health is addressed early

DIAGNOSIS DU JOUR?DIAGNOSIS DU JOUR?1980’S ADHD

1990’S DEPRESSION

2000’S EOBPD

Page 4: Early Onset Bipolar Disorder and the  Pediatric Behavior Rating Scale ™  (PBRS ™ )

RATES OF DIAGNOSISRATES OF DIAGNOSIS4,000% increase in rate of EOBPD

diagnoses in the past 10 years (Frontline, 2008)

At present, over 1 million American children have an EOBPD diagnosis, and the number is steadily increasing (Frontline, 2008)

PROBLEMS IDENTIFYING PROBLEMS IDENTIFYING BPD IN CHILDRENBPD IN CHILDREN

EOBPD is not in DSM IV.

EOPBD looks like other disorders.

EOBPD has high rates of comorbidity.

EOBPD vs. Adult BPDEOBPD vs. Adult BPD

(Birmaher et al, 2008; Danielyan et al, 2007; Kowatch et al, 2005)

EOBPD Adult BPDMixed Mood Episodes are typical

Discrete Mood Episodes are typical

Ultra-Rapid Cycling is common

Longer cycles

Symptomatic most of the time

Periods of no symptoms between cycles

PROBLEM 1: EOBPD PROBLEM 1: EOBPD isn’t in DSM IVisn’t in DSM IV

Bipolar Disorder-Not Otherwise Specified◦Rapid alternation between manic and

depressive symptoms that do not meet the duration criteria for manic, hypomanic, or major depression

◦Hypomanic without depression◦Infrequent episodes

Disruptive Behavior DisordersADHD60-93% meet diagnostic criteria for ADHD (Biederman,

et. al, 2003)Mania versus hyperactivityMore anger, irritability, aggressive temper tantrumsPresence of elation, grandiosity, racing

thoughts/flight of ideas, decreased need for sleep, hypersexuality

PROBLEM 2: EOBPD mimics PROBLEM 2: EOBPD mimics other disordersother disorders

ODD77-88% have ODD (Wozniak et. al, 1995)

More intense irritability and severe emotional meltdowns

CD42-69% have CD (Biederman, et. al, 2003)

Violent and aggressive behavior lacks intent, planning, and premeditation

PsychosisPsychosisTillman et al (2008), 257 EOBPD participants, ages

6-16, funded by NIMHPsychosis was present in 76.3% of subjects

◦38.9% with delusions Grandiose was most common

◦5.1% with pathological hallucinations Visual hallucinations were most common

◦32.3% with both

Page 15: Early Onset Bipolar Disorder and the  Pediatric Behavior Rating Scale ™  (PBRS ™ )

DEVIANCEDEVIANCEVOLUNTARY - we have a tendency

to attribute misbehavior—especially noncompliance and disobedience--to willful disobedience.

INVOLUNTARY - we tend to minimize this even when it explains the child’s behavior.

Page 16: Early Onset Bipolar Disorder and the  Pediatric Behavior Rating Scale ™  (PBRS ™ )

EOBPD and AROUSAL EOBPD and AROUSAL

Children with EOBPD are less able to modulate arousal live in fear are “on alert” for danger are primed for “fight/flight” response

And when aroused, aggression is more likely.

TWO WAYS TO ACHIEVE TWO WAYS TO ACHIEVE THESE GOALSTHESE GOALS

Medications (to make the child “available”)

Psychotherapies (coping & managing)

Page 22: Early Onset Bipolar Disorder and the  Pediatric Behavior Rating Scale ™  (PBRS ™ )

General Rule for InterventionsGeneral Rule for InterventionsBehavioral approaches tend to focus on

consequences.

There are two problems with this…

Page 23: Early Onset Bipolar Disorder and the  Pediatric Behavior Rating Scale ™  (PBRS ™ )

TWO PROBLEMSTWO PROBLEMS

1. By definition, children and adolescents with deficits in impulse control and self- regulation do not consider consequences before they act.

2. Behavioral consequences (especially if they are aversive) introduce provocation, confrontation…and escalation.

WHY A NEW RATING SCALE?WHY A NEW RATING SCALE?

• Existing scales came out normal

• Item analysis told us why

• The need for differential diagnosis

Page 40: Early Onset Bipolar Disorder and the  Pediatric Behavior Rating Scale ™  (PBRS ™ )

OTHER SCALESOTHER SCALES• Young Mania Rating Scale–Parent Version (P-YMRS; 11 items)

• General Behavior Inventory (GBI; 73 items; age 11; self-report accuracy)

• Child Mania Rating Scale (CMRS; mania only)

• Conners’ Abbreviated Symptom Questionnaire (ASQ; 10 mania items from the Conners’ Parent Rating Scales [CPRS])

• Omnibus rating scales (e.g., Clinical Assessment of Behavior [CAB], Achenbach System of Empirically Based Assessment [ASEBA], Behavior Assessment System for Children [BASC])

Page 41: Early Onset Bipolar Disorder and the  Pediatric Behavior Rating Scale ™  (PBRS ™ )

PURPOSEPURPOSE• For children and adolescents ages 3-18 years

• Primary function: To assist in the identification of emotional dysregulation and related disorders, specifically early onset bipolar disorder (EOBPD)

• Secondary function: To aid in differential diagnosis, leading to differential interventions

Page 42: Early Onset Bipolar Disorder and the  Pediatric Behavior Rating Scale ™  (PBRS ™ )

FEATURESFEATURES• Sufficient items to identify core features of EOBPD, such as:

Mood swingsIrritabilityGrandiosityEasily provokedExplosive outbursts

• Syndromal differentiation (e.g., ADHD vs. EOBPD)• Identifies areas of concern rather than providing diagnoses

TOTAL BIPOLAR INDEXTOTAL BIPOLAR INDEX• TBI is a composite of the 8 scales

• The most robust PBRS score (like g on IQ tests)

• T scores >70 are a significant concern for disorders of emotional dysregulation; T scores >80 suggest EOBPD

• The most effective way to differentiate EOBPD from other diagnoses (especially ADHD)
