The equivalence of an Internet administration of personality tests with two other administration formats was assessed using Item Response Theory (IRT) and various other statistical methods. The analyses were conducted on measures of Neuroticism, Extroversion, Agreeableness, and Conscientiousness. A total of 728 participants took part in the study. Participants were randomly assigned to one of three administrative conditions: paper-and-pencil, proctored computer lab, and unproctored Internet. Analyses with IRT, factor analysis, criterion-related validity, and mean differences supported the equivalence of Internet and traditional paper-and-pencil administrations of personality tests.
