Mental imagery during daily life: Psychometric evaluation of theSpontaneous Use of Imagery Scale (SUIS)

摘要

The Spontaneous Use of Imagery Scale (SUIS) is used to measure the tendency touse visual mental imagery in daily life. Its psychometric properties wereevaluated in three independent samples (total N = 1297). Weevaluated the internal consistency and test-retest reliability of thequestionnaire. We also examined the structure of the items using exploratory andconfirmatory factor analysis. Moreover, correlations with other imageryquestionnaires provided evidence about convergent validity. The SUIS hadacceptable reliability and convergent validity. Exploratory and confirmatoryfactor analysis revealed that a unidimensional structure fit the data,suggesting that the SUIS indeed measures a general use of mental imagery indaily life. Future research can further investigate and improve the psychometricproperties of the SUIS. Moreover, the SUIS could be useful to determine howimagery relates to e.g. psychopathology.
