説明
Inclusion Criteria:
- Sickle cell disease that is confirmed by hemoglobin analysis
- Has a brain magnetic resonance imaging (MRI) document reading by a neuroradiologist

- Must be a student who will remain in school for at least 2 years
- Must provide informed consent with assent in accordance with the institutional policies (institutional review board approval)
Exclusion Criteria:
- Known developmental delays (these participants are ineligible because their learning potential may be biased from a prior insult)

メジャーの説明 |
時間枠 |
---|---|---|
Full Scale IQ (FSIQ) (WASI)
時間枠:After >/= 50 hours of tutoring
|
The WASI is a brief, reliable measure of intelligence.
Participants engage in 4 subtests: Block Design, Vocabulary, Similarities, and Matrix Reasoning.
Participants receive a raw score on each of these 4 subtests.
This raw score is converted to a T score using a score chart in the WASI manual.
The T scores from all 4 subtests are summed together to obtain a Full Scale Sum of T Scores.
This Full Scale Sum of T Scores is converted to a Full Scale IQ-4 Composite Score using a score chart published in the WASI manual.
Higher scores indicate better intelligence.
FSIQ-4 Range: 40-160.
Average FSIQ-4 =100, standard deviation is +/- 15.
|
After >/= 50 hours of tutoring
|
Verbal IQ (PIQ) (WASI)
時間枠:After >/= 50 hours of tutoring
|
The VIQ score is comprised from the Vocabulary and Similarities subtests of the WASI-4.
The raw scores from these subtests are converted to T scores using score charts in the manual.
The T scores are summed together for a Verbal Sum of T Scores.
This score is converted to a Composite VIQ score using a score chart in the manual.
Higher scores = better Verbal IQ.
Range = 45-160.
Average = 100; standard deviation +/- 15.
|
After >/= 50 hours of tutoring
|
Performance IQ (PIQ) (WASI)
時間枠:After >/= 50 hours of tutoring
|
The PIQ score is comprised from the Matrix Reasoning and Block Design subtests of the WASI-4.
The raw scores from these subtests are converted to T scores using score charts in the manual.
The T scores are summed together for a Performance Sum of T Scores.
This score is converted to a Composite PIQ score using a score chart in the manual.
Higher scores = better Performance IQ.
Range = 45-160.
Average = 100; standard deviation +/- 15.
