Normative data for equivalent, parallel forms of the judgment of line orientation test

The Judgment of Line Orientation Test (JLO; Benton, Hamsher, Varney, & Spre en, 1983) permits assessment of visuospatial processing without making dema nds on motor skills. However, its administration can be time-intensive and frustrating for patients, particularly when used in a geriatric population. We present a single set of normative data to be used for both the odd-item and even-item forms derived from Form V of the no based on responses from a healthy geriatric sample. Mean scores and distributions of odd-item and e ven-item forms were nearly identical, and both forms showed significant cor relations with the Developmental Test of Visual-Motor Integration. Cross-va lidation using the odd form of the JLO on an independent sample from a diff erent geographic location suggested good generalizability of the normative data. We conclude that these JLO short-form normative data may be used in c linical screening situations or when serial assessments are needed.
