Attention Deficit Hyperactivity Disorder Rachel J. Valleley, Ph.D. Assistant Professor, Pediatrics Munroe-Meyer Institute, UNMC
Current Conceptualization Attention-Deficit Hyperactivity Disorder (ADHD) DSM-IV, 1994 Three subtypes: • Predominantly Inattentive • Predominantly Hyperactive/Impulsive • Combined
Adolescent and Adult Outcomes • Chronic disorder lasting into adulthood • 1/3: Tolerable outcome mild problems - adapt to difficulties • 1/3: Moderately poor outcome variety of problems such as school, vocational, adjustment difficulties, interpersonal problems, underachievement, problems with alcohol • 1/3: Poor outcome severe dysfunction including repeated criminal activity, alcoholism and drug use. Pittsburgh ADHD Longitudinal Study, Molina and Pelham
Cause of ADHD No one cause identified. Not caused by • Diet (i.e. food additives, sugar) • Poor parenting
Prevalence of ADHD Standard estimate: 3%-5% More recently: 12% (Fabiano & Pelham, 2001)
Attention-Deficit Hyperactivity Disorder Diagnosis: Who has ADHD?
Formal Diagnostic CriteriaDSM-IV, 1994 Criterion A: Six or more symptoms from one or both of these lists: • Inattentive Type • Hyperactive/Impulsive Type …have been present for at least 6 months.
Inattentive Type fails to attend to details, makes careless mistakes difficulty sustaining attention in play or work does not listen when spoken to does not follow through difficulty organizing tasks avoids task requiring sustained mental effort loses things needed distracted by extraneous stimuli often forgetful Hyper/Impulsive Type often fidgets hands/feet or squirms often leaves seat when sitting is expected runs about or climbs excessively difficulty playing or engaging in leisure activities quietly often “on the go”/ “driven by motor” talks excessively blurts out answers before questions completed difficulty awaiting turn interrupts or intrudes on others Symptom Lists
Formal Diagnostic CriteriaDSM-IV, 1994 Criterion B: Some of the symptoms were present before the age of seven years.
Formal Diagnostic CriteriaDSM-IV, 1994 Criterion C: Some impairment from the symptoms is present in two or more settings (e.g., home, and school or work).
Formal Diagnostic CriteriaDSM-IV, 1994 Criterion D: There is evidence of clinically significant impairment in social, academic, or occupational functioning.
Formal Diagnostic CriteriaDSM-IV, 1994 Criterion E: The identified symptoms are not better accounted for by another mental disorder.
Other Common Causes of Attention & Hyperactivity Symptoms • Oppositional Behavior • Learning difficulties • Depression/anxiety • Drug/alcohol use • Physical illness • Adjustment
Associated Problems • Oppositional Defiant Disorder: 35 - 65% • Learning Disability: 25 - 30% and variable academic quality • Poor social skills, peer relationships • Often overlooked! • Difficulties in family functioning
Attention-Deficit Hyperactivity Disorder Assessment: All that wiggles is not ADHD
Comprehensive Diagnosis for ADHD There is no single test or laboratory measure which can reliably detect ADHD.
Comprehensive Diagnosis for ADHD Information gained by qualified clinician: • From family • standardized, norm-referenced ratings • detailed history • From school • standardized, norm-referenced ratings • academic history • in-class observations • From clinician • observations
Parent Behavior Rating Scales • Conner’s: quick and dirty screening for ADHD and ODD • CBCL/BASC: screen for a variety of problems • Eyberg: screen for most common behaviors that drive parent crazy • ADHD-IV: screens for hyperactivity/impulsivity and inattention symptoms • Disruptive Behavior Disorder: screens for ODD & CD • Narrative summary to assess for impairment
Teacher Behavior Rating Scales • Conner’s: quick and dirty screening for ADHD and ODD • CBCL/BASC: screen for a variety of problems • ADHD-IV: screens for hyperactivity/impulsivity and inattention symptoms • Disruptive Behavior Disorder: screens for ODD & CD • Narrative summary to assess for impairment
Youth Behavior Rating Forms • If appropriate: • CBCL to screen for a variety of problems • Reynold’s Adolescent Depression Scale • Reynold’s Child Manifest Anxiety Scale • Childhood Depression Inventory
When to refer? • Screening measure indicates elevation in Hyperactivity/Impulsivity and/or Inattention symptoms • Unclear if other explanation for symptoms • Don’t have time for comprehensive evaluation
What to expect if referred to me • Meet for initial appointment to determine if evaluation is warranted (screening measure already completed is helpful) • Conduct comprehensive evaluation • Present treatment options based upon diagnosis • Send back to physician if want medication and/or need verification of diagnosis for school
What we know works: • Drug Therapy • Behavior Therapy • Combined Behavioral/Drug Treatments APA Task Force on Evidence-Based Treatments, JCCAP, Pelham, Wheeler, & Chronis, 1998
What we know DOESN’T work: • Play therapy • Individual or family counseling (without altering the environment) • Social skills/self-monitoring/organizational planning. • Dietary management • Megavitamin therapy • Sensory integration therapy/chiropractics • Biofeedback
Medications for ADHD Ritalin Adderall Cylert Dexedrin Strattera Concerta
What Medications Can Do Manage symptoms • Decrease activity level • Decrease impulsivity • Increase attention or “focus”
What Medications Can Do Improve associated features • Decrease “defiance” • Decrease aggression • Suppress negative social skills
What Medications Can’t Do • Teach new, appropriate behaviors Compliance/rule-following Self-management • Teach content previously missed Academic work Social skills • “Cure” ADHD
Stimulant Medications: Considerations • Effective for 70-75% • Higher doses associated with more side effects • Positive effects are lost when drug discontinued
Stimulant Medications:Contraindications • Under six years of age • High anxiety level • Thought disorder • History of tics or Tourette’s Syndrome • Risk of drug abuse • Unacceptably high levels of negative side effects
Limitations to Medication Treatment • Rarely sufficient to bring a child into normal range of functioning. • Works only as long as taken. • Not effective for all children. • Doesn’t affect several variables (e.g., academic skills, family problems). • Poor compliance with long-term use. • Parents not satisfied with medication alone. • Removes incentives to work on other treatments. • Lack of long-term evidence for effects. • Potentially problematic side-effects.
Behavior Therapy for ADHD Components • Highly Structured • Immediate Feedback reinforcer or reward for appropriate behavior punishment for inappropriate behavior • Salient/Meaningful Feedback
Common Behavior Interventions • Daily Behavior Report Card • Token Economy • Parent Training
Daily Behavior Report Cards • Daily note is sent between home & school regarding child’s behavior • Target behaviors monitored throughout the day • Performance on note determines consequences at home and/or school
Academic Behaviors Working on assignments Completing homework Handing in assignments All work up to date On time for class Social Behaviors Remained in seat Talked in turn Respectful behavior Got along with peers Following instructions Hands to self Daily Behavior Report Cards
Daily Behavior Report Card • Benefits • Keeps communication open between child’s environment • Helps monitor whether behavior is changing • Can monitor impact of medication • Takes very minimal adult time • Helps child get lots of positive feedback throughout the day
Token Economies • Arbitrary token (e.g., poker chip) given for demonstrating appropriate behavior • Tokens lost for inappropriate behavior • Tokens exchanged for reinforcers • This type of intervention becomes highly individualized based upon behaviors targeted, what is reinforcing to the child, and in what settings it is used
Parent Training • Increase positive interactions for appropriate behavior • Child-Directed Interaction • Role of Attention • Access to Tangibles • Decrease negative behaviors • Time-out (up around 8 years) • Job card grounding (around 8 and older)
Limitations of Behavioral Interventions • Often not sufficient to bring a child into the normal range of functioning. • Must be broad in scope to affect important familial variables. • Lack of evidence for long-term effects. • Difficult to get parents and teachers to do over a long period of time. • Costly compared to medications.
Which to employ? • The NIMH Multimodal Treatment Study • Largest NIMH-funded study of child mental health concern • 579 children at multiple sites • Group comparisons including: • Community Treatment • Psychosocial Treatment Only • Medication Only • Combination of BT and Meds
Which to employ? • Summary of Findings • All four groups improved with time. • Combined > Behavior on all measures. • Combined > Medicine on most measures of impairment but not symptoms. • Combined and sometimes Medicine > CC. • Combined produced more normalization at lower doses than Medicine; was more preferred by parents.
Which to employ? Change in Presenting Problem
Which to employ? Satisfaction with Child’s Progress
Which to employ? Overall Satisfaction with Treatment
