VOLUNTEER BIAS AND THE 5-FACTOR MODEL

We correlated consent granting for release of standardized test scores and willingness to be followed up in longitudinal research with measures of the five-factor model of personality in introductory psychology students. As predicted, agreeableness and openness to experience predicted volunteering in both situations. Extraversion also predicted willingness to be followed up in a longitudinal study. The results are consistent with the Rosenthal-Rosnow (1975) review of the literature on volunteer effects and extend that literature by relating it to the five-factor model of personality.
