Psychological determinants of health and performance: the tangled web of desirable and undesirable characteristics.

Correlations were determined for male (n = 225) and female (n = 242) college students between sets of undesirable personality traits (anxiety, stress reactivity, anger, and alienation) and desirable personality traits (instrumentality, achievement strivings, and optimism measured by the Scheier-Carver [1987] Life Orientation Test), and a series of outcome variables related to health (self-reported health complaints and health maintenance behaviors and beliefs) and academic performance (academic expectations and actual grade point average). Significant correlations were found between many of the personality variables and the outcome variables. However, partial correlations revealed different relationships for the various criteria. With other variables held constant, health complaints were related to several undesirable characteristics, whereas health maintenance behaviors and beliefs were related to several desirable attributes. Only achievement strivings made an independent contribution in both sexes to the 2 measures of academic performance. The theoretical and methodological wisdom of using measures of multiple personality constructs and outcome variables is discussed.
