Abstract. A short five-factor personality inventory developed from the International Personality Item Pool (IPIP) was imple-mented as an online questionnaire and completed by 2,448 participants. Following factor analyses, a revised version was created with acceptable reliability and factor univocal scales. As preliminary evidence of construct validity, support was found for 25 hypothesized links with self-reports of relevant behaviors and demographic variables. In a replication using a different recruiting strategy to test for differences due to motivational factors, similar results were obtained. This set of scales appears to provide acceptable measures of the Five-Factor Model for use in internet-mediated research
