Machiavellianism and medical career choices

Students' moral reasoning, Machiavellianism and socially desirable responding: implications for teaching ethics and research integrity

OBJECTIVE

To investigate the relationship between psychological constructs related to professional and research integrity and moral reasoning among medical students.

METHODS

Medical students, 2nd-year (n = 208, 85.6% of 243 enrolled students), answered the moral reasoning test-defining issues test 2 (DIT2) and the Machiavellianism and Paulhus socially desirable responding (SDR) scales.

RESULTS

Students had the highest score on the post-conventional schema of moral reasoning (mean +/- standard deviation, 35.2 +/- 11.6 of a possible 95) compared with personal interest (27.2 +/- 12.3) and maintaining norms schemae (29.2 +/- 11.5; P < 0.001, repeated-measures anova). Female students scored higher than their male collegues on post-conventional moral reasoning (37.6 +/- 11.0 versus 31.2 +/- 22.4, P < 0.001, independent-sample t-test). Of all 4 Machiavellianism subscales students scored highest on deceiving, where female students scored higher than their male colleagues (24.5 +/- 4.2 versus 22.9 +/- 5.1 of a possible 30; P = 0.037, independent-sample t-test). Female students also scored higher on the impression management subscale, whereas their male colleagues scored higher on the self-deception subscale of the Paulhus SDR scale. Moral reasoning scores were associated with cynicism, deceiving and flattering Machiavellianism scores, but not with Paulhus SDR scores. Multiple regression analysis showed the Machiavellianism amorality score as a significant negative predictor (beta = -0.183, P = 0.017) and female sex as a positive predictor (beta = 0.291, P < 0.001) for the post-conventional schema score on the DIT2. The Machiavellianism flattering score was a significant negative predictor for the personal interest schema score (beta = -0.215, P = 0.006).

CONCLUSIONS

Although moral reasoning is generally seen as independent of variables related to personality, our study indicated that Machiavellianism, especially its amorality and flattering subscales, were associated with moral reasoning. These results have important implications for teaching ethics and the responsible conduct of research in different cultural and socio-economic settings.

Machiavellianism: dimensionality of the Mach IV and its relation to self-monitoring in a Spanish sample

The aim of this study was to assess the measurement model of a Spanish version of the Mach IV Scale (Christie, 1970b), used to measure Machiavellianism, and its relation with the Self-Monitoring Scale (Snyder & Gangestad, 1986). 346 undergraduate students (70 males and 276 females) filled in both scales. The results of confirmatory factor analyses showed a four-factor structure to be the most adequate model for the Mach IV, with the following factors: Positive Interpersonal Tactics, Negative Tactics, Positive View of Human Nature, and Cynical View of Human Nature. These results are not in accordance with the original factor structure but are consistent with other authors' findings. A structural model between Machiavellianism and self-monitoring was tested, showing statistically significant paths between interpersonal tactics and one self-monitoring subscale.

Psychiatric residents' scores on Machiavellianism

For self-reports by 21 psychiatric residents on measures of Machiavellianism and Uncertainty no significant difference was noted by year in residency program, education, age, or gender.
