Applicability of the 15-item versions of the Judgement of Line Orientation Test for individuals with traumatic brain injury.
OBJECTIVE
To determine if short forms (i.e. 15 item) of the Judgment of Line Orientation (JOLO) test are equivalent to the full JOLO (i.e. 30 item).


METHODS
Retrospective analysis of JOLO test performance.


METHODS
Seventy-two persons with TBI evaluated at a Midwestern University neuropsychology laboratory were administered the JOLO test, Form V, as part of a larger battery of neuropsychological tests. Short forms (i.e. odd and even number short forms) were correlated with the 30 item to determine equivalency of forms. The Statistical Package for the Social Sciences (version 10) was used for the data analyses (SPSS).


RESULTS
Pearson's correlations indicate that the JOLO odd and even short forms are significantly correlated with the full JOLO score (r = 0.90 and 0.93, respectively), and that 100% of the participants' estimated JOLO full score fell within 2 points of the actual full JOLO score.


CONCLUSIONS
The results confirm the validity of the short forms of the JOLO for persons with TBI and that gender effects were not significant.
