Data Type Notes:
DESCRIPTIVE HISTORY:
The Army Alpha Examination (forms A and B) is a combination of the five
forms of Alpha used in the United States Army during World War I. The questions best for
general use were selected by order-of-merit method. Items addressed
specifically to male recruits were excluded and military terms were modified.
Form A of this paper-and-pencil examination, consisting of eight subtests, was
administered to all subjects beginning in 1960. Form B was administered on
visit five (six to eight years later), and Form A repeated on visit nine; the two forms were
given alternatively on all subsequent visits. When subjects reached age 70
and was tested every year, the form of the test given on the last previous visit was
repeated. A speed score was obtained for each subtest by stopping the subject
after the time specified, while a power score was obtained by permitting the
subject to spend as much time as he or she wanted in completing each test.
DATA COLLECTION INSTRUMENT, METHOD, OR MEDIUM:
The test was administered and scored using the standard published instructions.
