Dream Intensity Scale: Factors in the phenomenological analysis of dreams.

Abstract

The present study aimed to develop a comprehensive assessment tool for measuring subjective dream intensity by revising the original probes and response scales of the Dream Intensity Inventory and incorporating new variables. The factor analyses suggested that 18 items of the new instrument, Dream Intensity Scale, could form four scales and six subscales. The revision of the probes and response scales did not have major effects on the clustering of the indicator variables, which was highly consistent with the original three-factor measurement model. The alpha coefficients, interitem correlations, and item-scale correlations indicated a good internal consistency for the Dream Intensity Scale. Moreover, the convergent and discriminant concurrent validity of the Dream Intensity Scale and the clinical utility of its scale and subscale scores were substantiated by their selective correlations with neuroticism and extraversion.
