Some Psychometric Properties of the Spanish Version of the Clarity of Auditory Imagery Scale

Abstract

Few tests have been designed to measure auditory imagery. This study assessed the factor structure and internal consistency of the Spanish version of the Clarity of Auditory Imagery Scale (CAIS). Participants were 234 undergraduate students ( M age = 19.6 yr.). Internal consistency reliability estimated by Cronbach's alpha was .82. In a principal components analysis followed by varimax orthogonal rotation, five factors were identified. Scores correlated moderately and positively with ratings on the Vividness of Visual Imagery Questionnaire–2 and negatively on the auditory scale of Betts' Questionnaire Upon Mental Imagery, but weakly and negatively with scores on the Measure of the Ability to Form Spatial Mental Imagery.
