Short videos have become popular online content. This study experimentally examined the feasibility of presenting items of an online psychological questionnaire as short videos (VQ) and compared this method to a traditional text-based administration (TQ) using a convenient online sample of N = 321. VQ was administered either by a male (VQM) or a female (VQF) interviewer. Strict measurement invariance was established across both methods for both inventories used. No significant differences emerged in the methods' break-off rate, reliability, or criterion validity. Respondents' self-reported ability to focus did not differ between VQ and TQ. Similarly, no differences between the methods were found in an attempt to measure respondent's focus objectively. It seems that neither the social desirability nor the interviewer effect had any notable negative influence on VQ. The completion time was faster in VQM but not VQF compared to TQ, suggesting that video administration is not necessarily slower. Respondents rated VQ as the more enjoyable method. There was also a visible improvement in model fit indices in the VQ over TQ for both employed inventories. The results of this exploratory study imply that videos could be an advantageous form of psychological questionnaire administration, although replication is necessary.
