Two alternate forms of the ASP (Part 1) were developed, each consisting of SO items
in multiple choice format with two to five response options. The items sampled construcIs
representing delinquency, ‘academic achievement, career and work orientation, athletic
involvement, and social adaptation. Item option scoring weights were developed utilizing
Guion’s (1965) “horizontal percent” method in a randomly assigned scale construction sample
(N = 26,857, Army, Navy, Air Force, and Marine Corps combined samples). This resulted
in a three-point item scale and a single total summed score. In a national sample of military
applicants (N = 120,175), the mean item reliability (item to rota1 score correlation) was .2 1
and the estimates of internal consistency were .76 and .74 (coefficient alpha for the two
forms). The predictive validity of the ASP was compared to the folIowing measures: Armed
Forces Qualification Test (AFQT); education credentials (2 years college, high school diploma,
high school equivalency certificate/GED, and no secondary credential); employed at time of
application; 17 years of age at time of service entry; and eligibility waiver status as a result
of preservice misdemeanor or felony arrests.
The criterion is a dichotomous measure of attrition. Personnel who were voluntarily
or involuntafily dishaged from serbice prior to the completion of their service contracts were
coded ” 1”. Those personnel with medical disability, officer school discharges, service breach
of contract, and the dead were excluded from analysis. All other personnel were coded as “0”.
