OBJECTIVE: The researcher examined the relationship between clinical scale scores on the MMPI-2 and the total amount of driving errors made on a driving simulator in male and female adults.
METHOD: The sample consisted of 155 (male: n = 61 and female: n = 94) adults (mean age = 29.94, SD = 13.26; mean education = 15.44, SD = 2.09; 64.5% Caucasian; 14.8% Hispanic/Latino; 14.8% African-American). The data were derived from an ongoing de-identified database of clinical patients and student volunteers. All of the Clinical scales on the MMPI-2 and the total amount of driving errors were examined.
RESULTS: A regression analysis was conducted between the MMPI-2 Clinical scales scores and the total driving errors that occurred on the driving simulator.
RESULTS of this analysis were considered significant at the p < 0.01 level. The association was positive suggesting that subjects with elevated scores on scale 4 are associated with increases of driving errors on the driving simulator, β =.360, SE =.116, p =.002. The remaining Clinical scales were not significant predictors.
CONCLUSION(S): Clinical scale 4, which measures anti-authority and abuse tendencies was a significant predictor of total driving errors made on the simulator. This result could be due to the fact that those who have an elevated scale 4 score tend to dislike authority and make decisions/rules for themselves, because they believe they are more qualified to do so than others. It is possible that those who carry this personality trait tend to get into risky driving situations. Although some of these results were significant, further research is still needed.
