The Dreamland: Validation of a Structured Dream Diary.
Frontiers in Psychology January 1, 2020 Brigitte Holzinger, Lucille Mayer, Isabel Barros et al.
The Dreamland Questionnaire (DL-Q), a new instrument for analyzing dream content, was validated against the established Hall and van de Castle Coding System (HVDC). Twenty-two participants provided written dream reports and completed the DL-Q, yielding 30 dreams for comparison. Correlations between the two measures were high for dominant characters, pleasantness of dream content, and body-related experiences. Some DL-Q items showed low correlations, and others could not be directly compared because the HVDC lacked equivalent items. The DL-Q demonstrates satisfactory validity and reliability for assessing dream criteria and may serve as a useful tool for clinical and research purposes, though further validation is needed for certain items.
