Hadley, Erin (12/08) The impacts of defensive functioning and anxiety on risk taking behaviors (Howard McGuire, Ph.D.; Gary Kose, Ph.D.; Joan Duncan, Ph.D.)
The present study addressed the relationships between defensive functioning, anxiety, and risk taking in 79 undergraduate students. This study avoided several methodological limitations of previous research by measuring multiple types of risk taking and using updated assessments to quantify both anxiety and defensive functioning. Principle measures were well-normed psychometric tests with established reliability and validity (e.g., the State-Trait Anxiety Inventory). Interrelationships among measures of state and trait anxiety, defensive functioning styles, and three types of risk taking were examined.

As predicted, increased levels of specific defense styles were associated with higher levels of hypothetical life-or-death risk taking, self-oriented risk taking, and experimental risk taking on a betting task. However, a hypothesized inverse relationship between anxiety and risk taking was not confirmed. The study also supported previous research that identified risk taking as a domain-specific construct. This finding indicates that risk taking behaviors do not occur consistently across situational variables but are situation-dependent.
