Traditions of

Formulation

Psychodynamic: Freud (1907)

Psychobiology: Meyer (1948)

DSM 1-5 (1952-- )

Community Psychiatry

Bio-psycho-social: Engel (1977); Grinker

(1954?)

The Perspectives: McHugh and Slavney, 1983.

The Perspectives

“... seeks to systematically apply the best work of behaviorists, psychotherapists, social scientists and other specialists long viewed as at odds with each other.”

The Perspectives

• Disease perspective

• Dimensional perspective

• Behavioral perspective

• Life Story perspective

The Disease Perspective

• A disease is a mechanistic syndrome

• What a person has

• A disease requires cure or amelioration

The Disease Perspective

• Parkinson’s

• Schizophrenia

• Autism spectrum disorder (ASD)?

• Bipolar Disorder

• Depression

• Obsessive compulsive disorder

• Tourette’s

• ADHD

• Etc.

The Dimensional Perspective

• Intelligence

• Learning Disorders

• Communication issues

• Personality

• ASD?

The Dimensional Perspective

• A dimension has relative value

• Who a person is

• Dimensional extremes require guidance

Temperament Example:

• “Difficult”?

• “Defiant”?

• Unstable?

• Extroverted?

• Too open?

• Disagreeable?

• Not concientious?

The 5 Factor Model (FFM)

• Stable ---------- Unstable

• Extroverted ---------- Introverted

• Open to new ---------- Closed to new

• Agreeable ---------- Disagreeable

• Conscientious ---------- Not conscientious

The Behavioral Perspective

• Motivated vs. Maladaptive behaviors

• What a person does

• Stop “bad” behavior

Motivated Behaviors

• Disorders of eating

• Disorders of sleep

• Disorders of sexual expression

• Substance misuse

Maladaptive Behaviors

• Oppositional

• Self-centered

• Contextual

• Often learned

Life Story Perspective

• The narrative of a person’s life

• What a person (or others) understands about a person’s experiences

• Reframe negative life story concepts

Preferences and Bias

• Disease

• Dimension

• Behavior

• Lif Story

Contrasting Dx Approaches

• Clinical diagnosis

• Standardized testing

• Setting specific

Framing Bias:

Everyone is an Expert

Diagnosis Stakeholders

• Children and parents

• Teachers, administrators, school personnel

• Social workers and other therapists

• Psychologists and other evaluators

• Psychiatrists, pediatricians, neurologists

• Academia

• Pharmaceutica

• Insurance companies

• Pundits and politics

Pharmaceutical Controversy:

Stakeholders

• Federal Government

• Academic Community

• Treatment Community

Assessment Errors

• Cliché errors

• Desperation

• Insufficient data

• Lack of comprehension

• Misattribution errors

• Misinformation

• Oversimplification

• Relationship errors

• Reformulation to avoid labels/medications

“Expert” Errors

• Relationship errors

• Primary attribution error

• Misattribution errors

• Cliché errors

• Reformulated symptoms to avoid stimulants

Primary Attribution Error

• Your behavior is suspect, based on your flaws

• My behavior is a rational response to a situation

(including your flaws)

ADHD: Cliché Errors

• “S/He can concentrate when it’s something that s/he wants to do..”

• “S/He can sit still if s/he wants to…”

• “Too much ____ (e.g. TV, video, computer, cell phone, facebook, etc.) is all… ”

• “S/He started faking it this year, when school got hard…”

More Cliché Errors

• “In our day we didn’t have ADHD…”

• “If ADHD exists, it’s not so bad…”

• “I had ADHD and I turned out fine…”

• “ADHD is over-diagnosed…”

• “ADHD is over-treated…”

Still More Cliché Errors

• “The real problem is the drug companies…

• … the doctors…

• … the teachers…

• … the times we live in…

• … those darn kids/parents... short cuts”

ADHD: Misattribution Errors

• Bad seed

• Boys will be boys

• Poor parenting

• Normal response to stress

What is ADHD, Really?

• Attention deficit: cannot ignore competing stimuli

• Hyperactive/Impulsive: equivalent

• Disorder of executive function (EF)

• EF frames the ADHD symptoms

What is Executive Fx, Really?

• “Whatever the frontal lobes do”- Denkla

• “Conscious direction … efficient processing of info.” -Stuss and Benson

• “Maintenance of behavior on a goal ... calibration... to context” - Pennington

• “Self regulation across time for the attainment of one’s goal... - Barkley

Self-Regulatory Mini-Modules

(Barkley 2012)

• Inhibition

• Self-directed sensory-motor actions

• Self-directed attention

• Working memory

• Planning and problem solving

• Self-motivation

• Emotional self-regulation

Impairment of Executive

Activation

• Attention

DSM Evolution

I (1952) : Atheoretical, standardized definitions

II (1968): “Legitimacy”, patient education

III (1980): More ICD, more reliability; Axis I-V

III-R (1987): Same trends

IV (1994)/IV-TR (2000): Same trends, behind quickly

DSM-5

“Transcend limitations... beyond current ways of thinking”- but field not ready for a paradigm shift

Empirical evidence grounds

Continuity

“Living, evolving document”

Aspirations: etiological, objective, dimensional

DSM-5 Field Trial

Design

11 centers,Test-retest reliability or agreement:

Cohen’s Kappa: inter-rater reliability

DSM-5: 0.61 “very good”, cutoff-- 0.4-0.6

“good”

0.20.4 “questionable”-- <0.2 “unacceptable”

DSM-III: cutoff-- 0.71 “good-very good”

DSM-5 Controversy

NIMH distancing from DSM-5

Strength in reliability, weakness in validity

Will no longer fund research projects that rely exclusively on DSM criteria

Research Domain Criteria (RDoC): NIMH

Research Domain Criteria

(RDoC): Assumptions

Dx approach based on biology and symptoms

(not constrained by DSM-5)

Biological disorders/brain circuits implicate specific domains of cognition, emotion, or behavior

Each level of analysis... across a dimension of function

Mapping cognitive, circuitry, and genetic aspects will yield new/better targets for treatment

RDoC

Negative Valence Systems

Positive Valence Systems

Cognitive Systems

Social Processing Systems

Arousal/Modulatory Systems

Overview of Changes

Categorical to dimensional; early detect/prevent

Dimensional measures included, e.g. “crosscutting symptom measure”, “WHODAS”, and

“severity scale for schizophrenia”

Axis I-V dismantled

NOS replaced: Other specified disorder,

Unspecified disorder

New disorders, “renamed” disorders

DSM-5: Axis I-V

Replaced

Non-axial documentation

Important psychosocial /contextual factors (V and Z codes)

Disability (may be replaced with the

“WHODAS”)

GAF is eliminated (see above)

DSM-5

Metastructure

Changes

Regrouping of disorders

Putative underlying factors

Underlying vulnerabilities

Groups juxtaposed by relationship

Within groups, ordered by age of onset

Pediatric Modifications

Shortened duration: cyclothymia- 1 year vs. 2 year

Alternative symptom expression: MDD- irritable mood...

Lowered symptom threshold: GAD1 from “C” in children

Suspended criterion: OCD- behavior not aimed at alleviating anxiety

Special criteria: PTSD age <6- only 1 symptom required- avoidance plus negative cognition/mood

Life Cycle: ADHD

Symptoms

Preschool: more hyperkinesis

School age: inattention appears

Adolescence: inner restlessness

Adulthood: inattentive complaints, but impulsivity reigns

Elements of a

DSM-5 Diagnosis

Dx criteria

Dx subtypes and specifiers

Severity qualifiers are gone

Principal Dx

Provisional Dx “strong presumption full criteria will be met”

Co-morbid vs. Diff. Dx?

• Common disorders co-exist w ADHD

• Common disorders also masquerade as

ADHD

• Co-morbidity amplifies symptoms

School Referral, “ADHD”, age 7

Psychiatric Diagnosis

• Medical model psychiatric history/MSE

• Corroborative data

• Rating Scales

• Neuropsych/Cognitive-Eductaional testing

• Ruling in/ruling out other syndromes

Rating Scales

Rating scales are screening and measuring tools

Rating scales are not diagnostic scales

ADHD/behavior: Connors, ADHD IV, Vanderbilt,
