Abstract
This study’s primary purpose was to examine the overall quality of the factorial structure of the Dream Intensity Inventory (DII). It was hypothesized that dream intensity was a multifaceted construct that could be accounted for by 3 latent factors, namely Dream Quantity, Dream Vividness, and Altered Dream Episodes. The 1st-order oblique, 1st-order orthogonal, and 2nd-order models, which represented 3 possible versions of the structural relations among the 3 latent factors, were subjected to the confirmatory statistical procedures. The goodness-of-fit indices indicated that the 2nd-order model and the 1st-order model hypothesizing 3 oblique factors were superior to that hypothesizing 3 orthogonal factors. The factorial characteristics of the two well-fitting DII models were shown to be equivalent across 2 samples. These results suggest that the theoretical construct of dream intensity can be pertinently described by the 3-factor measurement model. (PsycINFO Database Record (c) 2016 APA, all rights reserved)
