Stanford-Binet: Fourth Edition short forms with underachieving and learning disabled students

Area of Science:

• Educational Psychology
• Developmental Psychology
• Psychometrics

Background:

• Academic underachievement and learning disabilities present significant challenges for students.
• Accurate screening tools are crucial for timely intervention and support.
• The Stanford-Binet Intelligence Scale is a widely used measure of cognitive abilities.

Purpose of the Study:

• To evaluate the validity of partial composites derived from the Stanford-Binet Intelligence Scale: Fourth Edition.
• To determine the suitability of these partial composites for screening academic underachievement and learning disabilities.
• To compare correlation coefficients with existing literature.

Main Methods:

• Administered the Stanford-Binet Intelligence Scale: Fourth Edition to 55 students referred for academic underachievement or suspected learning disabilities.
• Calculated Pearson product-moment correlation coefficients between the full Test Composite and 6-, 4-, and 2-test Partial Composites.
• Compared obtained coefficients with those reported for other populations.

Main Results:

• High Pearson correlation coefficients were obtained: .98 (6-test Partial Composite), .95 (4-test Partial Composite), and .90 (2-test Partial Composite).
• These strong correlations indicate good agreement between the full composite and the derived partial composites.
• The results suggest the reliability of shorter test versions for specific diagnostic purposes.

Conclusions:

• Partial composites of the Stanford-Binet Intelligence Scale: Fourth Edition demonstrate high reliability.
• These partial composites are suitable for screening academic underachievement and learning disabilities.
• The findings support the use of abbreviated test batteries when appropriate, enhancing efficiency in assessment.
