To examine the possibility of a gender difference in symptom reporting, a chi-square analysis was conducted in the claimant sample. Five of 37 items had to be deleted from the analysis due to insufficient cell size. Only four of the thirty-seven items had sufficient cell values. Given the lack of gender effects for the claimant population, gender was no longer considered in the analysis. The percentages of claimant and control patients reporting each complaint are depicted in Table 1.
Symptoms are rank ordered by frequency of reporting in the claimant patient population.
Additionally, results from chi-square analysis and significance level for each item are included. Note that for the majority of items, there is a significant difference in symptom reporting. All significant differences indicate the claimant group was more likely to endorse the symptom than was the control group. When claimants were asked if they knew the cause of these complaints, they attributed the overwhelming majority of these complaints to the events which led them to file their claim. This is a difficult assumption in litigation due to a host of extraneous forces which complicate forensic neuropsychological evaluations.
