Using the Trail Making test to screen for cognitive impairment in a drug abuse treatment sample.
The Trail Making test (TMT) is a brief paper and pencil neuropsychological test often used for screening for cognitive impairment. The value of the TMT is examined in a sample of 5619 males and 2902 females was drawn from electronic files of data from the Drug Abuse Treatment outcome Study (DATOS), a naturalistic, prospective cohort study that collected data from 1991-1993 in 96 programs in 11 cities in the United States. Data were analyzed to determine the effects of specific drugs of abuse on parts A and B of the TMT in this large sample of patients in drug abuse treatment programs. Most subjects, regardless of type of drug abused, on TMT parts A and B appeared to fall within normal limits relative to commonly accepted cutoff scores. These results suggest that the TMT parts A and B would have great value as screening measures for cognitive impairment in a drug abuse treatment population.
