Protocol Name from Source:
Block Design Test subtest of the Wechsler Adult Intelligence Scale®, Fourth Edition (WAIS®-IV)
Personnel and Training Required
Personnel should be trained to administer the test by a licensed neuropsychologist or other trained medical professional experienced with the Block Design test. Additionally, investigators are encouraged to have quality control procedures (such as videotaping sessions, etc.) in place to maintain consistency across examiners.
The interviewer will need a copy of the test that includes the images, blocks for the respondent to recreate the designs, and a copy of the scoring instructions.
|Specialized requirements for biospecimen collection||Yes|
|Average time of greater than 15 minutes in an unaffected individual||No|
Mode of Administration
Adolescent, Adult, Senior
Adolescents and adults, ages 16 and older
Block Design is a proprietary subtest of the Wechsler Adult Intelligence Scale®, Fourth Edition (WAIS®-IV). Each WAIS-IV subtest is a part of a complete WAIS-IV assessment and is not sold separately. To administer a subtest requires a licensing agreement from Pearson. Researchers should complete and return an application to firstname.lastname@example.org.
Block Design was selected because it is a widely used, validated protocol that requires less time to administer than similar instruments.
Process and Review
Expert Review Panel 4 (ERP 4) reviewed the measures in the Neurology, Psychiatric, and Psychosocial domains.
Guidance from ERP 4 included the following:

A performance-based task to assess spatial judgment and visualization skills.
This measure tests a respondent’s total range of function with respect to spatial reasoning. It is therefore more specific and sensitive than a measure of global mental status and can be used to assess major problems in spatial reasoning (e.g., due to head trauma or Alzheimer’s disease) as well as minor variations that may be a consequence of normal development and aging.
