ADI

Question 1

ADI
What does the measure assess? (can think about why it was developed)

Answer 1

Caregiver sem-structured interview
Help diagnose ASD through
** current behaviour and developmental
history**

Important basis for diagnosis

Question 2

ADI
Target population (age, special populations, etc.

Who administers?

Answer 2

Target Population: Non-verbal mental age of at least 2 years old

Administered by bachelors +training or master’s

Question 3

ADI
What scales are included?

Answer 3

3 domains of functioning

1. Language and Communication
2. Reciprocal Social Interactions
3. Restrictive, repetitive & stereotyped behaviours and interests

Question 4

ADI
What is involved in the assessment (e.g. materials, administration details, general scoring guidelines)

Parts of assessment
Interviewing
Scoring - algorithms and steps to score

Answer 4

Administration:
1. Background
2. Introduction
3. Early Development
4. LC
5. Social development and play
6. Interests and Behaviours
7. General Behaviours

Interviewing:
- Detailed descriptions, discrepancies, cues, open ended, non-leading, behaviour comparison to other kids

Scoring
Diagnostic algorithm:
- Dev history - researched and validated
Current Behaviour algorithm:
- Last 3 months behaviour, estimates functioning for treatment planning
Options: Current, Ever, Most Abonormal, specific age
AGE: Both algorithms difffer based on age - which to use

1. select algorithm
2. convert raw scores using conversion
3. Add scores from each section
4. Interpret scores
   - Consistent Disconfirming - maybe no but need ADOS, if ADOS yes caregiver unreliable
   - Confirming - yes and need ADOS
   - Mixed Results - clinician discretion, might be another disorder

Question 5

ADI
Is it reliable / valid? Limitations/benefits of
standardization?

Answer 5

R/V:
-high test retest
-discriminate btw LD and ASD
- Converges with ADOS & DSM
- predictive of stable diagnosis

Standardization:
- Flexibility in probing
- Trained person
- Aligns with DSM and ICD10

Question 6

ADI
Under what situation might you choose to administer the assessment? Consider the benefits & limitations?

Answer 6

-Use to diagnose ASD
-Use when caregiver is involved
-Assess social interaction & communication

Question 7

ADI
what are some benefits & limitations of the assessment?

Answer 7

Benefits
-Focuses on developmental history vs. ADOS present behavior
-Provides info about behaviour across settings.
- Differentiates ASD from other dev disorders.

Limitations
- Time consuming 1.5-2.5
- Dependent on informant report
- Cultural/linguistic bias
- Cost and training

Question 8

ADI
How is the assessment similar / different from others discussed in the course?

Answer 8

Differences
1. Interview vs ados observational
2. administered to caregiver vs. ados individual
3. focus on dev history vs. focus on standardized tasks/activities

Both ADI and ADOS used to:
- Assess ASD
- trained clinicians
- Comprehensive assessment
- Assess social interaction/communication
