Factor Analysis and Validation of the Disturbing Dream and Nightmare Severity Index in an Inpatient Sample

CONCLUSIONS: The DDNSI was found to be a valid measure of nightmare frequency and distress, as it was significantly correlated with the items related to disturbing dreams, and the DDNSI was able to differentiate between nightmares and psychopathology symptoms. Though this research comes nearly two decades after the initial creation and use of the DDNSI, it provides a foundation for the scientific rigor of previous and future studies on nightmares using the DDNSI.PMID:38402579 | DOI:10.1080/15402002.2024.2319835
