Internal consistency and concurrent validity of two short forms of the Visual Form Discrimination Test.

The purpose of this study was to evaluate the reliability and concurrent validity of 2 short forms of the Visual Form Discrimination Test, referred to as first half (FH) and front-back (FB). Participants were a mixed sample of 225 patients seen for neuropsychological evaluations. The mean difference score between both short forms and the full form was less than 1 point. The short-total correlations were .85 and .86 for the FH and FB forms, respectively. A binary clinical decision rule, used to classify patients as normal or impaired, resulted in a 93.3% correct and a 94.7% correct classification rate for the FH and FB forms, respectively. It is concluded that the short form of the test, used in conjunction with a clinical decision rule, results in a very minor loss of accuracy.

Intercorrelations and internal consistency of limb muscle-action strengths of patients with renal disease.

This study involved the retrospective analysis of instrumented measurements of strength from six muscle actions of 15 patients with renal disease. Most measurements were correlated significantly (Cronbach alpha > .92). These findings extend those obtained in studies of healthy individuals and patients with stroke and suggest the presence of a common underlying construct, limb muscle strength.
