Reporting of demographic variables in neuropsychological research: trends in the current literature

Demographic variables have long been known to exert effects on psychological testing. Variables such as age, education, and gender have been thoroughly researched, and their effects are well documented. Other demographic variables such as race, ethnicity, socioeconomic status, native language, and acculturation are less well researched within the field of neuropsychology. Research that has been produced to date has demonstrated that each of these variables does indeed wield some effect on neuropsychological test performance. Therefore, it is important that these variables be reported in the literature so that neuropsychologists are able to generalize research findings to their everyday practice with patients from diverse backgrounds. With this in mind, the current study was undertaken in order to determine the frequency with which a range of demographic variables are being reported in current neuropsychological research journals. Publications from 1995 to 2000 in five of the most frequently utilized neuropsychology journals were reviewed. Results showed that while age, education, and gender are frequently reported, information on race, ethnicity, native language, and acculturation are rarely, if ever, reported. These results show that even though great strides have been taken in the burgeoning field of cross-cultural neuropsychology, current trends need to be changed in order for progress to continue.
