The study collected Eysenck Personality Inventory scores from 1,421 undergraduate students and recorded their stated willingness to participate in future research. Results showed that scores matched Eysenck’s American college norms, females and extraverts were more inclined to volunteer, and a logistic regression revealed an interaction between Neuroticism–Stability and Extraversion–Introversion affecting volunteering probability, highlighting potential bias in volunteer-based research.
Scores on the scales and subscales of the Eysenck Personality Inventory were obtained from a sample of 1421 undergraduate students. The students were also asked to indicate their willingness, in principle, to participate in further research. The scale scores obtained do not depart greatly from those norms given by Eysenck for American college students. Females are somewhat more likely to volunteer than males, and, generally, extraverts are more likely to volunteer than introverts. However, a logistic regression analysis showed that Neuroticism‐Stability interacts with Extraversion‐Introversion to increase or decrease the probability of volunteering. The results may have important implications for research findings based on data collected from volunteer subjects.
