Development of the Japanese Version of the Vividness of Odor Imagery Questionnaire

Abstract

We developed the Japanese version of the Vividness of Odor Imagery Questionnaire (VOIQ). Responding to a survey, 556 participants completed the VOIQ and the Japanese version of the Vividness of Visual Imagery Questionnaire (VVIQ). Factor analysis verified the one-factor structure and demonstrated it to be sufficiently reliable (Cronbach's α=.80). The validity of the questionnaire was also confirmed by middle correlations of the total score between VVIQ and VOIQ. The results indicated the validity and reliability of the questionnaire.
