Short forms of the Benton Judgment of Line Orientation Test: development and psychometric properties.
The Benton Judgment of Line Orientation Test (BJLOT) is a widely used neuropsychological test measuring visuospatial judgment. The present study developed two 15-item short forms using data from 100 neurologic patients. The new short forms are equivalent in test construction and retain the stimulus properties of the original test. Correlational analyses revealed that each short form score related significantly to the original BJLOT (p <.001). The short forms were found to be internally consistent, with alpha reliability coefficients exceeding .82. Although kappa coefficient analyses found the short forms to lack sufficient accuracy in categorizing the cases via the BJLOT diagnostic classifications, the short forms were accurate in detecting the presence of impairment. These results suggest that the two short forms can be utilized as screening instruments for detecting the presence or absence of visuospatial impairment.
