Using versions of the trail making test as alternate forms.

Alternate forms of neuropsychological instruments are often made parallel by developing tests with similar numbers of items, formats, and psychometric properties. The present study offers an alternative approach by examining three different trail-making tests that could potentially be used as alternate forms. Over a 3-week period, the Trail Making Test of the Delis-Kaplan Executive Functioning System (DK-TMT), Comprehensive Trail Making Test (CTMT), and Connections Task (CT) were individually administered to 154 undergraduate psychology students in each of six possible orders.
