Historical Perspective of Attention Deficit

• Originally referred to as “minimal brain dysfunction” • 1980

DSM-III

identified attention deficit with hyperactivity (ADHD) and attention deficit without hyperactivity (ADD) and based diagnosis on the three core symptoms of

- Sustained attention - Impulsivity - Motor activity

• ADHD youth tend to be more disruptive and aggressive than ADD youth • ADHD youth have more comorbid psychiatric and educational disorders (e.g., conduct problems, LD, poor peer relations) • More recent developments have focused on separating ADHD from other psychiatric conditions (e.g., bipolar disorder, anxiety, under socialized youth) • ADHD has 8% to 10% prevalence rate (APA, 2000); more males than females

Historical Perspective of Attention Deficit

(continued)

ADHD as a lifelong condition - Early conceptualizations were that adults outgrew ADHD

Follow-up studies revealed - 30% to 80% of children with ADHD continued symptom manifestation into adulthood - Lower adult educational and occupational success - Lower socioeconomic status - More difficulty with co-workers and employers - Higher incidence of psychopathology - Increased likelihood of substance abuse

ADHD Residual Type (DSM-III-R) - Continuation of ADHD symptoms into adulthood

Historical Perspective of Attention Deficit

(continued)

American Academy of Pediatrics (AAP)

To confirm a diagnosis of ADHD, related behaviors must:

Occur in more than one setting, such as home, school, and/or social situations.

Be more severe than in other children of the same age.

Begin before the child reaches 7 years of age.

Make it difficult for the person to function at school, home, and/or in social situations.

DSM-IV ADHD Criteria

Six or more symptoms of inattention present for at least 6 months to a point that is disruptive and inappropriate for developmental level: Inattention

Inattention to details; makes careless mistakes in school, and/or other activities.

• • •

Has difficulty attending to tasks or play activities. Does not seem to listen when spoken to. Does not follow instructions and fails to finish schoolwork, and/or chores.

• •

Often has difficulty organizing activities. Often avoids, dislikes, or does not want to sustain mental effort for a long period of time.

• • •

Loses things needed for tasks and activities.

Easily distracted. Forgetful in daily activities.

DSM-IV ADHD Criteria

(continued)

Six or more of the following symptoms of hyperactivity-impulsivity present for at least 6 months to an extent that is disruptive and inappropriate for developmental level: Hyperactivity

Fidgets with hands or feet or squirms in seat.

Gets up from seat when remaining in seat is expected.

Runs about or climbs when and where it is not appropriate (adolescents may feel very restless).

Has difficulty playing or enjoying leisure activities quietly.

Is often “on the go” or often acts as if “driven by a motor.”

Talks excessively.

DSM-IV ADHD Criteria

(continued)

Six or more of the following symptoms of hyperactivity-impulsivity present for at least 6 months to an extent that is disruptive and inappropriate for developmental level: Impulsivity

Blurts out answer before question has been completed.

• • • •

Has difficulty waiting one's turn. Interrupts or intrudes on others (e.g., butts into conversations). Some symptoms present before age 7 years. Some impairment from the symptoms is present in two or more settings (e.g., at school, at home).

Clear evidence of significant impairment in social and/or school functioning.

Symptoms do not happen only during the course of a pervasive developmental disorder, schizophrenia, or other psychotic disorder. Symptoms are not better accounted for by another mental disorder (e.g. mood disorder, anxiety disorder).

DSM-IV ADHD Criteria

(continued)

Based on these criteria, three types of ADHD are identified:

ADHD, Combined Type are documented .

: if criteria from inattention, hyperactivity, and impulsivity

ADHD, Predominantly Inattentive Type and hyperactivity are not .

: if inattention is documented, but impulsivity

ADHD, Predominantly Hyperactive-Impulsive Type : if hyperactivity and impulsivity are documented, but inattention is not.

Clinical Assessment of Attention Deficit

Ages - 8 to 18 years

Three forms - Self-Report - Parent Report - Teacher Report

Features

Features

(continued)

Employs a four-point item response format

-

Strongly Agree Agree Disagree Strongly Disagree

Is accompanied with optional CAT Software Portfolio (CAT-SP) that scores, profiles, reports data, and facilitates interpretation

-

Standard scores (T scores)

-

Percentile ranks Confidence intervals Qualitative classifications Graphical profile display

Features

(continued)

Assesses behaviors that correspond to DSM-IV/AAP

-

Clinical symptoms: inattention, hyperactivity, impulsivity

-

Multiple contexts: school/work, social, personal Differentiates sensations (internal) from actions (external) Normed to address issue of developmentally inappropriate levels

Software scoring program scores, profiles, reports, and stores examinees’ data

Multiple applications

Constructing the CAT-C

A Multidimensional, Multi-Step, Multi-Year Process

Content Identification and Item Development

1.

Approached the CAT from Bracken’s (1992) context-dependent model of adjustment 2. Reviewed and evaluated existing attention deficit scales 3. Identified relevant content

• • • •

Literature on attention deficit Item content on existing instruments Current diagnostic criteria from DSM-IV Suggestions from colleagues 4. CAT-C developed after CAT-A (adult form) to match item content on the CAT-A

Item Tryout, Norming, and Finalization

5.

42-item child form (CAT-C) - CAT-C Self-Report - CAT-C Parent Report - CAT-C Teacher Report 6.

CAT-C forms were piloted and validated (N = 50), resulting in 83% to 88% correct classification of ADHD and control students 7.

CAT-C scales were normed, validated, finalized, and published

Veracity Scales

Negative Impression − degree to which an individual consistently responds in a negative manner.

Infrequency − extent to which an individual endorses items in an extreme manner that the normative sample did not endorse in an extreme manner.

Positive Impression − extent to which an individual responds in an unusually positive manner.

Validity

Types of validity investigated

Content validity (DSM, literature)

Concurrent validity (i.e., convergent/discriminant) - Connors Rating Scales - Attention-Deficit/Hyperactivity Disorder Test - Clinical Assessment of Behavior - Clinical Assessment of Depression

Construct validity - Intercorrelations - Exploratory factor analyses

Contrasted groups (i.e., ADHD, LD)
