설명

Inclusion Criteria:

  • Sickle cell disease that is confirmed by hemoglobin analysis
  • Has a brain magnetic resonance imaging (MRI) document reading by a neuroradiologist
  • Cognitive deficits, which are defined by one standard deviation lower than the normal ranges of an age-based standard score in cognitive tests that are evaluated by a psychologist
  • 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)
  • Intelligent quotient is less than 50 (may have impaired learning potential)
  • Aphasic (i.e., unable to produce intelligible speech)

결과 측정
측정값 설명
기간
Full Scale IQ (FSIQ) (WASI)
기간: 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)
기간: 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)
기간: 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.
After >/= 50 hours of tutoring
Letter Word Identification T Score (WJ-III)
기간: After >/= 50 hours of tutoring
This sub-test measures a student's word identification skills. A participant's raw score (# of items answered correctly) is converted to a T score using a program (Compuscore for the WJ III, Version 2.1). Higher T scores = better performance. Range: 0-100. Average T score = 50; standard deviation =/- 10.
After >/= 50 hours of tutoring
Reading Fluency T Score (WJ-III)
기간: After >/= 50 hours of tutoring
This sub-test measures a student's ability to read simple sentences quickly. A participant's raw score (# of items answered correctly) is converted to a T score using a program (Compuscore for the WJ III, Version 2.1). Higher T scores = better performance. Range: 0-100. Average T score = 50; standard deviation =/- 10.
After >/= 50 hours of tutoring
Calculations T Score (WJ-III)
기간: After >/= 50 hours of tutoring
This sub-test measures a student's ability to perform paper and pencil math computations.A participant's raw score (# of items answered correctly) is converted to a T score using a program (Compuscore for the WJ III, Version 2.1). Higher T scores = better performance. Range: 0-100. Average T score = 50; standard deviation =/- 10.
After >/= 50 hours of tutoring
Math Fluency T Score (WJ-III)
기간: After >/= 50 hours of tutoring
This sub-test measures a student's ability to solve simple addition, subtraction and multiplication facts quickly. A participant's raw score (# of items answered correctly) is converted to a T score using a program (Compuscore for the WJ III, Version 2.1). Higher T scores = better performance. Range: 0-100. Average T score = 50; standard deviation =/- 10.
After >/= 50 hours of tutoring
Spelling T Score (WJ-III)
기간: After >/= 50 hours of tutoring

California Verbal Learning Test-Children's Version (CVLT-C) List A Trials 1-5 Immediate Recall T Score
기간: After >/= 50 hours of tutoring
The CVLT®-C measures multi-trial learning and long-term recall abilities for verbal information. The Raw scores from all trials (1-5) are summed to calculate a Total Raw Score for Trials 1-5. This Raw score is converted to a T score using the CVLT-II Comprehensive Scoring System (computer system). A higher T score indicates better performance. Range = 0-100. Average =50 with a standard deviation of =/- 10 points.
